SID-40B RESERVE SUPPLY AUTO-TRANSFER DEVICE
1. General
1.1 Application
An uninterruptible power supply is the important assurance for national economy normally operating, the
power system development and technical advance is toward the goal. The assurance of uninterruptible power
supply relays on every stage of power generation and transmission. But the traditional design of reserve supply
auto-transfer devices can not fulfill modern customer’s diversified requirements, especially in some industry
enterprise where it is forbidden because it have been harm to large motor loads. SID-40B reserve supply
auto-transfer device improved many old problems on the study traditional device and requirements on power
supply reliability, especially industry enterprise. A new name “Reserve supply auto-transfer device’ is given to
distinguish from traditional devices.
The important precondition for improving reliability of power supply are more than two supply sources
acquirable and the swiftly successful reserve supply auto-transfer with no harm to the supply and consumption
device when normal electrical source is cut by protection operation which keeps the uninterruptible power supply
to electrical consumer and the most even all loads online and quickly re-supplied. This control system is not only
transfer but also protects production from interruption, which should be the ultimate aim of reserve supply
auto-transfer. The physical characters follow the voltage loss varies according to the different load property. For
resistive load, the bus voltages descend to zero immediately. But for inductive or capacitive load, the bus voltages
decreases gradually. The decaying speed of bus with motor loads depends on motor quantity, capacity, and
mechanical characteristic. After loss of power, motors become asynchronous generators as mechanical inertia and
rotor residual magnetism remains, generating decreasing voltage and frequency on the bus. It is easy to see that
different transfer mode shall be applied according to load property to haste reloading.
There are three starting conditions in traditional reserve supply auto-transfer device, ① the normal supply
disconnected ( use “no current” as criterion); ② the reserve supply in normal (use “voltage enabled” as criterion);
③ the bus voltage equal to zero (use “no voltage” as criterion). Obviously, the condition ①and condition ② are
correct, but the condition ③ is unilateral and localized. If the bus voltage drops to zero, all loads have been shed
and the motors stop running, the production is interrupted. By the time, even if the reserve supply put in can not
avoid havoc to the technique flow, not to say the wicked condition when a number of motors self-start. The
traditional reserve supply auto-transfer device designer worrying about that put the reserve supply in when bus
voltage very high will make the electric equipment especially motor, mangled. Since the voltage that a motor can

endure for a long time is 1.1~1.2 times rated voltage as given by the manufactories, their original intention, the
worry, however, actually, is redundant, and here, we call the voltage that the motor can withstand for a long time
withstand voltage. We get the conclusion that it is safe to devote the reserve supply so long as the voltage imposed
on motor does not exceed this value. So the modification that amend the condition ③ as load withstanding
voltage lower than withstand voltage which enable no load loss in reserve supply transfer is much reasonable.
Based on different load property reserve supply transfer condition is different, we have design in SID-40B
reserve supply auto-transfer device: fast transfer criteria, capture motor-group withstand voltage rule; capture first
point in phase; capture residual voltage criteria. Users can choose criteria according to load property on the spot
and complete the reserve supply transfer quickly and reliably. Remark that on some complicated spot, for example
there is private generator or cold backup transformer on the bus, a control system with powerful function can be
built up by SID-40B reserve supply auto-transfer device as the center and assist with SID-3YL inrush current
suppressor, synchronizer, low frequency-low voltage load shedding device and other intelligent control device
developed by our company to realize transfer continuously with no disturb in varied application.

2.1 Fast transfer function illumination
The fast transfer function refers that SID-40B can complete switch between working supply and reserve supply
fast. Include: fault switch, accident switch and manual switch. There are different modes and different switch rules
for each kind of switch. You can choose them according to the actual situation.
2.1.1 Switch reason explanation

Fault switch
The fault switch is drove by protection contact or analog value. The protection input can be connected to
differential protection, generator and transformer protection output. The analog value includes frequency
difference actuate, frequency difference no-current actuate, reverse-power actuate, reverse-power frequency
difference actuate and frequency-voltage quality actuate. When protection actuate, service supply trip first then
backup supply connected upon preset condition (Or adjustable delay). Mode can be serial or simultaneity.

Accident switch
The accident switch is implemented automatically, including two situations:
Bus voltage loss start: when the three phase voltages (special parameter select phase voltage) or three line
voltages (special parameter select line voltage) of bus are lower than set point and last longer than the delay
time, as well as the working breaker is closed, and the incomer voltage is lower than Normal-volt. Set, or the
working breaker in the sub-bit. the device will implement simultaneous switch or series switch according to the
mode chosen.
The working breaker mis-trip: when some reasons (including manual mis-operation) cause the working breaker
mis-trip, the device can implement series switch.


Manual switch
Manual switch is started by manual operation, and then complete automatically. When local manual switch
signal is detected or remote signal of switch is receive, the switch between working line and spare line starts. The
switch mode include series, simultaneous, auto-parallel, semi-automatic parallel, paralleling failed turn to series
and paralleling failed turn to simultaneous.
2.1.2 Switch mode explanation

Series switch
Trip working breaker first, when the working breaker is confirmed opening, the position contact and current are
correct, then close the backup breaker.

Simultaneous switch
Trip working breaker and at the process of tripping send out command of closing backup breaker, assure
working breaker open first and backup breaker close followed through setting closing delay-time. When working
breaker fails to trip off, there will appears looped network with the working source and reserve source supply at
one time. If the looped network running is not allowed in the system, you can set decoupling function and
decoupling time in the system parameter setting. Once the looped network running condition appears, and lasts for
decoupling time, trip the breaker that just closed in order to dissolve the looped network condition, completing the
decoupling function.

Auto-parallel switch
First close backup breaker based on parallel switch rule, when the backup breaker is confirmed at closed state,
trip the working breaker automatically. This mode is also supports decoupling function. The parallel switch rule
actually is strict double sides’ power supply synchronization switch rule. SID-40B supports different frequency
synchronization as well as same frequency synchronization. Note that this mode is used for normal manual switch
only.

Semi-automatic parallel switch
First close backup breaker based on parallel switch rule, when the backup breaker is at closed state, the working
breaker is tripped off by manual operation. Note that this mode is also used for normal manual switch only.

Paralleling failed turn to series switch
If the condition fits parallel switch rule, switch according to auto-parallel switch rule, otherwise switch
according to series mode. Note that this mode is also used for normal manual switch only.

Paralleling failed turn to simultaneous switch
If the condition fits parallel switch rule, switch according to auto-parallel switch rule, otherwise switch

according to simultaneous mode. Note that this mode is also used for normal manual switch only.
2.2 Reserve supply auto put in function explanation
The device possesses auto-transfer reserve supply function, can realize varied operating mode of one bus
breaker and four incomer breaker. In appendix 3, some common used running modes such as bus breaker or
bridge breaker switch, two incomers switch are illuminated in detail. The users can set the scheme according to
their needs by setting parameters. Furthermore, we can customize the scheme according to your demands.
The charging:
When incomer and bus voltage and every breaker state are at normal condition, the charging begins. The “Auto
switch “lamp on the panel begins to wink, and after ten seconds the lamp constant bright, it indicates that the
Reserve auto-transfer enter operation and monitor state.
The operation process:
Under monitoring state, if accident condition (bus voltage loss/ working breaker mis-trip) occurs or fault signal
(protection start signal of working supply breaker) is gathered, and the setting transfer condition is satisfied,
working breaker will transfer with backup breaker automatically. After transfer, no matter success or fail, the
device enters the state of affirm reset. It may not enter charging state to ready for next transfer until delay 10s and
remote or local reset operation is received.
Manual switch operation process:
When the breaker state is satisfied for manual switch condition, the “manual switch” lamp normal bright, and
the Reserve auto-transfer device enter the manual switch operation and monitor state. Under this state, if local or
remote manual switch signal is gathered, working breaker will transfer with backup breaker automatically. If the
operation fails, the device enter waiting affirm reset state. It may not enter charging state to ready for next transfer
until delay 10s and remote or local reset operation is received. If the operation succeeded, the device reset
automatically after 200ms.
2.3 Linkage open and linkage close function
Linkage open function is referred that the control strategy took between “Trip the work supply” and “Close the
reserve supply” of SID-40B.
Linkage close function refers to the following control function when supply transfer has been finished.
The linkage open and linkage close function can be map out according to the locale situation. They are mainly
used to remove or put in some specifically power supplies or load branches; and also used to control the flow and
rule of the switch.
There are soft switches for Linkage open and linkage close, which can be set in system set-point independently.

TV disconnection alarm function; 2 segments low voltage unloading
protection. The value, delayed time and
soft switch of each protection can be set independently in protection set-point.
2.4.1 The two segments low voltage unloading function
Low voltage unloading function segment 1 and segment 2 are set in the device. When switch finished, the
low-voltage unloading function open ten seconds. During this period, if bus voltage is detected lower than
low-voltage set-point and lasts for time setting, trip off some unimportant or hypo-unimportant load to ensure bus
voltage restore. Whether to remove the unimportant and hypo-unimportant load can be determined by the setting
of low voltage and time set-point of low voltage unloading segment 1 and segment 2. There is a switch soft strap
for this function, and it can be set in system set-point independently.
2.4.2 Bus linkage over-current protection segment 1
When bus linkage over-current protection segment 1 function is put in, bus linkage current is larger than
segment 1 set-point, bus breaker tripped after time set-point delayed
2.4.3 Bus linkage over-current protection segment 2
When the bus linkage over-current protection segment 2 function is put in, and the bus linkage current larger
than segment 2 set-point, bus breaker will tripped after time set-point delayed.
2.4.4 Bus linkage haste protection
When bus breaker changes from open to closed, the device opens haste protection for 5 seconds. During the
period if haste protection function is put in, bus linkage current is larger than current set point, the bus breaker
tripped after set time delayed.
2.4.5 Incomer over-current protection
The device provides incomer 1, incomer 2, and incomer 3 over-current protection. You can operate this function
according to the actual running of main bus connection. Over-current protection logics of the three incomers are
same. The soft strap is devoted, if incomer current larger than over current set value, then trip off each incomer
breaker by protection action. When the device is in the backup transfer monitor state or normal transfer condition
detecting, if over-current protection acted of either phase and the current direction is into the bus, then fast transfer
function will locked when protecting tripping, otherwise, the device will abnormally transfer of mis-trip startup
after tripping.

2.4.6 Incomer over-current instantaneous trip protection
The device provides incomer 1, incomer 2, and incomer 3 over-current instantaneous protection. Over-current
protection logics of the three Incomers are same. When incomer breaker changes from open to closed, the device
opens instantaneous trip protection for 5 seconds. During the period if instantaneous trip protection is put in and
incomer current is larger than current set value, trip off each breaker by protection action after delayed time.
2.4.7 Voltage loss alarm protection
When voltage loss alarm protection of every incomer and bus is put in and the voltage is lower than each
voltage loss alarm voltage set-point, the general alarm signal is port-out after voltage loss alarm set time delayed.
2.4.8 Incomer TV disconnection alarm
Each incomer TV secondary disconnection protection soft switch put in and incomer voltage lower than 70%
Un, after ten seconds delayed, alarm signal send by protection and device TV disconnection alarm signal is sent
out.
2.4.9 Bus TV disconnection alarm
Bus TV disconnection protection soft switch put in, the incomer breaker is closed, and the incomer voltage is
normal or incomer has current, single phase or three-phase voltages lower than 70% Un, after ten seconds delayed,
alarm signal sent by protection and device TV disconnection alarm signal is sent out.
2.5 Startup Post-reclose function
Startup Post-reclose function means send Post-reclose signal pulse to protection system after switched or
operated solely, Time of pulse can be set in set-point.
2.6 Automatic fault lock function
"Automatic fault lock function " is that the device determines whether the fault is happened the protect area (the
area fault including bus fault, bus load, power branch fault) through the test of bus voltage, incomer current, etc; if
the fault is happened in the protect area, the device will lock switch, to avoid inputting the standby power to the
fault point. Here is the principle of the fault:

Figure 1 Power consumption direction
(1) Power direction lock: When detected three-phase current of the power feed lines is any phase into the bus,
and the phase current amplitude is greater than "the maximum load current value" (please refer to the principle of
installing a protection device at work switch and relay protecting over-current 3 segment set-point), while at least
one bus line voltage lower than the "low voltage latch value" (recommended set 60 ~ 70% of rated voltage), the
device immediately closed all the switch startup criteria (including the protection of signal start, analog start) and
start the fault lock timer; if the fault current disappears or changes direction before " automatic fault identification
time set-point" , the device immediately open all the criteria, otherwise, the device automatically exit the monitor
status until the system back to normal condition (bus voltage back to normal few seconds). This criterion also
applies to the condition that bus voltage decline suddenly when starting a number of large motor. The set of
"automatic fault identification time set-point" can divide into two cases to consider:
First, bus protection was not installed in local. The value should be big enough under the premise of ensuring
that it’s less than the far backup protection time of work power. This is because that when the bus fails, it must
rely on far backup protect action of the incomer to remove the fault point if their has no bus protection in local,
and the majority of bus failure consider as a permanent failure, so the device must be exit the monitor status
before far backup protect action, to ensure that the backup power will not put on the fault bus when the low
voltage switch starting (the fault current disappears after the far backup protect action,). For the fault occurs in the
load branch, the device should immediately open all the criteria after the corresponding protect action, to avoid
missing operation when fault happens. Therefore, in this kind of local conditions, the longer far backup protect
action time of the incomer, the better selectivity of criterion on the bus fault and load branch fault. It’s reasonable
to set the backup protect action time a little longer on two and three segments about the power supply incomer
which equipped with full line quick-acting differential protection.
Second, bus protection installed in local or there basically has no risk of bus failure, so the value should be
－－－－－－－－－－－－－－－－－－－－－－－－－－9－－－－－－－－－－－－－－－－－－－－－－－－－

bigger than load branch protect action time, and at the same time use the busbar protect action signal as the
protection locking signal of 40A and 40B. The device exits the monitor status only when the load branch protects
missing operation.
Figure 2 Power consumption direction lock logic
(2) Voltage unbalance lock: since bus three phases almost balance when work power off as fault point out of the
protect area. Process as follow: confirm work breaker tripped, check whether voltage balance, if asymmetry rate
over 20%Un (eliminate normal load unbalance), lock three fast transfer criterions (‘fast switch’, ‘capturing
motor-group withstand voltage criteria’, ‘synchronization chaptering rule’) immediately until three phases balance;
but ‘Residual Voltage Switch’ and ‘Long Delay Switch’ are not locked, because they can fit the protection device
on the load branch by adjust action time, then implement reserve supply recolse when fault branch removed.
The two lock criterions above can choose open or close at will.
2.7 Event record function
The device possesses record function of remote signal event, protection event, wave record event, operation
event, self check event. Users can inquire record information like action time, event name through “event record”
on LCD screen.
2.8 Wave record function
The device begins to record wave once transfer is started. The wave recorded includes 25 cycles before start
and 50 cycles after start-up. Each transfer total wave recording time is 1.5 seconds and total twice. The device
storage is up to 12 groups of record data. The contents include bus voltage, bus current, incomer voltage, incomer
current and all digital input information e.g.. The wave recording event index can be looked over in “wave
recording event”, the waveform, record data can be displayed locally as well as transmitted to background
computer for analyzing.

3. Control principle
Figure 3 Main bus connections
Figure 3 is a typical supply system with double incomer and bus coupler collocated.
Mode 1: the two incomers supply to bus simultaneously, bus coupler is open, bus1 and bus2 reserve for each
other.
Mode 2: bus coupler is closed or system with only one bus but without bus coupler, one incomer is supplying
and the other is as reserve supply.
When working incomer fails, fast transfer is the optimal mode in order to make interruption time least. If the
state of system does not allow this switch mode, choose other mode whose speed is slower a little.
3.1 Fast switch
At the moment fast switch starting up, if the angle difference and frequency difference between bus and reserve
incomer are within the setting scope and bus voltage is not lower than fast switch low-voltage lock value, the “fast
switch” can start up, and close output immediately. According to local test data, decaying time and speed of bus
voltage magnitude and frequency is mainly related to the load that bus houses. More the load is on, slower voltage
magnitude and frequency decay and the decaying much faster as time flowing. It is the best choice to close
quickly for in the first 0.3s, the decaying of voltage magnitude and frequency is slower, and when angle difference
is within 60° it is a safe scope for electrical equipments. When frequency difference is average to 1Hz, the angle
difference between bus and reserve incomer increases 36° calculated according to the inherent switching time
100ms, so it is suitable to adopt fast switch to switch to ensure the success of fast switch, besides, when the device
gives out closing signal, the angle difference should smaller than 20°, namely the fast transfer angle difference
set-point is set to 20°.

Figure 6 Wiring diagram and equivalent circuit
If reserve supply is put in at a certain ΔU, we can view from figure 3.4 that one part of ΔU is imposing on reserve
line or transformer reactance XB , the other part imposes on equivalent impedance (XM) of bus load(mainly motor).
Generally, voltage that
motor can long-term withstanding is 1.1~1.2 times rated voltage, so motor is safe as long
as the voltage imposed on motor is not larger than this withstand voltage when put in reserve supply. People may
worry that if angle difference Φ too big when reserve supply put in may bring torsion impulse to shaft system of
motor, however the theory and practice prove that although the motor group is at asynchronous generating state, it
is virtually a generator that with no power source and no excitation source but rely on inertia to generate,
consequently reserve supply can draw the motors in with not too big impulse. In the situation that quantity and
capability of motors is biggish, the varying speed of Φ is slow, and the operation and control speed of device is
quite fast, so normally Φ when reserve supply put in is not bigger than 60°.
Furthermore, when reserve supply put in, the superposition of reserve supply voltage and sub-transient as well
as transient potential of motor may bring in biggish impulse which will possibly cause the action of reserve supply
quick-break protection, and the auto-transfer fails. Theory and practice prove that this problem can be resolved by
correctly choose reserve supply relay protection set-point. We adopt capturing motor-group withstand voltage
criteria to complete fast and safe switch for reserve supply, and we call this criteria capture motor withstand
voltage criteria. The approach to complete this rule is real time monitor and measurement of angle difference Φ
and ΔU, and forecast the variety of ΔU according to the sampled data, give out close command and complete the put

in operation of reserve supply before the time that ΔU exceeds the allowable value reckoning in the switching time of
reserve supply breaker. This is greatly in favor of restoration for it ensures all motors re-electrify when rotate speed
not very low and bus residual voltage still high.
ΔU is distributed according to the ratio of stand-by transformer (or line) impedance XB and load impedance XM.
Because the working transformer (or line) impedance XG and XB is known, we can continuously measure UG and UM
when normal running and calculate the real-time equivalent impedance of all loads on bus.
XM 
UM
XG
U G  UM
Once working supply is removed when fault present, record the last XM calculated, then through the known XB
can calculate the maximal allowable ΔU, namely ΔUmax. The safety and fast restoration of the entire load are ensured
if only the reserve supply be put in before ΔUmax comes. In fact, in the deceleration of motor, XM keeps on
descending, the allowable value ΔUmax calculated according to the XM and the XG which is the value at the
cutting-out moment is bigger than the actual value when reserve supply is put in, i.e. the actual voltage magnitude
that distributed to motor is smaller than that calculated, therefore this arithmetic is adding safer assurance to motor.
Figure 7 Static voltage characteristic curve of motor
It is especially note that at present middle-high type induction motors widely used in Industry Corporation bear
static voltage characteristic curve as shown in figure 7. It describes the relationship between terminal voltage V and
active power P as well as reactive power Q that motor absorbs from power supply. It is not difficult to see that when
motor terminal voltage declines near 60% of rated voltage, motor will heavily absorb reactive power, and active
power (torque) sharply declines. Therefore if reserve supply is put in when working bus voltage is lower than the
critical voltage Uk, the self-start condition will be greatly deteriorated and even motors fail to self start and reserve
supply is re-cut out because of over-current and low-voltage. To ensure the continuity of production, the reserve
supply should be put in before critical voltage Uk comes, in this way the supply contactor of motor in industry
corporation will no longer “shake” or “trip” caused by reserve supply’s slow put in.

variety law of frequency, phase angle and magnitude, calculate the time that bus residual voltage and reserve
supply first time in phase, when the time come give out closing command ahead of tripping circuit total action
time, completing close at accurate zero namely first point in phase. This switch mode is not affected by load
variety, and it is favor to self-start of equipment. The disadvantage is parts of the load will be cut off because of
the attenuation of bus residual voltage, all load that using contactor will lose the opportunity to re-electrify due to
the low-voltage release of contactor, the original production flow will impossible to restore after reserve supply
put in.
First point in phase switch which is considered as stand-by switch of withstand voltage rule is usually used in
the following situation:

Incapable of completing capture withstand voltage switch because the initial power angle is obviously big
because of connection or operating mode of system.

When frequency of residual voltage drops fast but the breaker closing time too long, it is difficult to complete
capture withstand voltage switch.

The working supply and the reserve supply belong to two independent systems. There is not only phase angle
difference but also frequency difference in the two systems.

When on working bus there is high capacity source whose capacity can almost satisfy the need of loads,
synchronization matter will appear when reserve supply is put in, so the synchronization mode is the
reasonable switch mode at the time, namely “fast speed auto-parallel”, see 3.6 for detail.
3.4 Residual voltage switch
The residual voltage switch is the switch which is completed when three line voltages descend to the value that
lower than or equal to residual voltage switch set-point (20%~40% of rated voltage), and last longer than residual
voltage switch time set. It is regarded as the reserve function of first point in phase switch as stated in front. When
working supply is removed by protection, if the aforementioned switches are not implemented, then when the
voltage decline to a certain value, close the reserve branch breaker. It is no need to judge the angle difference and the
frequency difference and it is an asynchronous switch mode.
Although residual voltage switch enable to ensure the put in of reserve supply, many equipment is cut off
automatically or by low-voltage protection because the interrupting time is too long. The self-start condition of some
other appliance is deteriorated and the production flow is affected.
3.5 Long delayed time switch
If in the assigned time the switch can not complete by any of the aforementioned switches mode, long delayed
time switch can be executed. The long delayed time switch is only used as a stand-by mode, and it will not work at

normal situation. Generally this mode is adopted only if fault happen many times in a short time.
3.6 Fast speed auto parallel
Aim at some high capacity power distribution systems, SID-40B made the concept "fast speed auto parallel" to
avoid "isolated network" operating state after excision of the working power; its meaning lies in rapid restore reliable
of electricity and improves power quality. Because there has all kinds of power supply inside the isolated network, to
avoid unnecessary disruption and disturbance, we must be implementing the synchronizing operation strictly to input
into the line of standby power. At this point use the bus voltage to reflect the voltage and frequency of isolated
network system, and form a synchronization point with the backup power voltage. In addition, the following is to
highlight:
（1）Conditions to start the device. Since it was very difficult to access the status of remote switch in most sites,
SID-40B made the frequency difference of bus and standby power as one of the conditions to start. Before
disconnection, so the frequency difference of bus and standby power is zero because they come from the same
system; after disconnecting, the standby power is essentially the same frequency, frequency change of bus is
determined by the power and load characteristic of the isolated network, which constitutes a certain frequency
difference. SID-40B has 300 ms internal start delay when using the frequency difference as the start condition,
mainly due to two things: First, escape the frequency measurement error caused by external fault; Second, to ensure
reliability of paralleling, the device need some time to accurately calculate the frequency change rate of the system.
As their exist different capacity of power supplies inside the isolated network, the frequency decreased much slower
than load alone, but it’s not suitable for paralleling when the frequency fell too fast (in this case SID-40B can put in
the standby supply after the bus voltage loss completely), so a few hundred milliseconds of delay has no effect on the
device to capture the first paralleling time. If the first paralleling time appears in the site that the system disconnects
more than a second, automatically paralleling has a high success rate.
(2) Lock conditions of paralleling, SID-40B follows four conditions on lock paralleling operation.
First, the backup power supply voltage is not normal and lower than the incomer voltage loss value;
Second, the frequency difference of bus and standby supply exceed the limit;
Third, the change rate of bus frequency exceed the limit;
Fourth, the bus voltage lower than the low voltage lock value;
(3) Frequency difference limits on paralleling of the isolated net system. The limit value depends on the one hand,
nature of the internal power supply (mainly synchronous generator) of the isolated networks, the larger capacity of a
single generator, the smaller of the limit value; on the other hand, as their has a large number of load within the
system, most of the active power exchange which generated by standby power input moment slip into the load

电源投切安全控制及相控技术专家
branch, so the limit value of frequency difference can larger than the value when the generator paralleling normally.
For the occasion that more than 10MW large-capacity generating units inside the isolated net, the proposed set is
3Hz; general situation can be set to 3 ~ 5Hz.
(4) Limits of the frequency change rate on paralleling of the isolated network system. After forming the isolated
status, the change rate of frequency is proportional to the difference of the active power about the system, as taking
into account the sudden increase and decrease when designing the synchronous generator, so it has a good tolerance
on the frequency change rate. Made it as a lock condition is to ensure the accuracy of paralleling operations and
improve disturbance rejection capabilities. SID-40B default value is 25Hz / S.
(5) Low-voltage lock value of bus voltage. General can be 50 to 60% rated voltage settings, as below this value,
the system disturbance is too large in the closing moments.
3.7 The setting of transfer set-point
Users can choose proper switch rule and parameters based on spot run equipment. The follow points are the
foundation of setting.
(1) When the load is mainly asynchronous motors, suggest select “Fast Transfer Logic” composing of fast transfer
rule and capture withstand voltage rule as primary transfer means and select residual voltage switch, long delayed
time switch to form “Slow Transfer Logic”, which can be applied as backup switch instrument. The scope of fast
switch rule set-point is: low voltage lock set-point 60~80% of Un, allowable frequency difference not larger than
1Hz, switch angle not larger than 30 º; capture withstand voltage rule set-point scope: low-voltage lock value 60~80%
Un, allowable frequency difference not larger than 4 Hz, withstand voltage not larger than 1.20 times of Un. The
setting area of Residual voltage rule is: residual voltage transfer set-point not lower than 30% of Un and time
set-point not longer than 1.00 Sec; the relative set-point of long delayed time switch can be set according to the
actual condition of the decay of system voltage.
(2) When there is big capacity synchronous motor in loads, suggest select “fast transfer logic” composing of fast
transfer rule and capture first point in phase rule as primary transfer means and select residual voltage switch, long
delayed time switch to form “slow transfer logic”, which can be used as backup switch instrument. The scope of fast
switch rule set-point is: low voltage lock set-point 60~80% of Un, allowable frequency difference not larger than
1Hz, switch angle not larger than 25 º; capture first point in phase rule set-point scope: low-voltage lock value 60~80%
Un, allowable frequency difference not larger than 5 Hz. If the transfer fails, cut off synchronous motor immediately
and carry out residual voltage switch. The setting scope of Residual voltage rule is: residual voltage transfer set-point
not lower than 30% of Un and time set-point not longer than 1.00 Sec; the relative set-point of long delayed time
switch can be set according to the actual condition of the decay of system voltage.

(3) When the load is mainly asynchronous motors and contain of synchronous motors at the same time, you can
operate following the process. Firstly cut off all synchronous motors by “Linkage open” when working supply is out.
And whereat put in reserve supply by capture withstand voltage rule. Moreover start up fast synchronization device
to merge synchronous motors into the system in synchronization mode by “Linkage close”. The “Linkage open” and
the “Linkage close” are the special control option of SID-40B, can be collocated according to different local demand.
(4) When the load system contains of capacitors, you can complete the operation by two modes: one is the
capacitors have compound with inrush current suppressor, and no discharge circuit. When the transfer system is
started, cut off capacitor immediately, put in reserve supply fast and start up SID-3YL inrush current suppressor to
merge the charged capacitor into system. The other is directly put in reserve supply according to fast transfer, capture
withstand voltage rules etc after the transfer device start up. If the AC voltage on bus is upper the capacitor may not
be removed, otherwise remove the capacitor and not put in automatically.
3.8 Soft logic of switch rule
If auto-parallel or semi-automatic parallel switch mode is selected in manual switch set-point, the switch will go
along according to beat frequency or same frequency synchronization rules strictly. The set-point in the
synchronization switch rule are parallel switch allowable voltage difference, parallel switch allowable frequency
difference, parallel switch allowable power angle difference.
If series switch or simultaneous switch is chosen in switch mode, the switch will go no by fast switch rule,
withstand voltage rule, synchronization chaptering rule, residual voltage rule or long delayed time rule. These five
switch rules can be chosen in manual switch set-point, fault switch set-point and accident switch set-point
independently through setting the on/off soft switch. Once the procedure enter the starting switch process, it will
calculate and judge each rule if is satisfied all the time in the longest switching time according to the on/off
situation of each rule. If any of the rules is satisfied and the sign of trip complete is supervised, give out the
command of close and close output. The soft logic is shown in picture 9.

Point Area” is the set point area which need to be monitored，press +/- to change Select Set Point Area
number. You can examine set point of ten areas. If the set point area selected is the same of the current one,
then you can check the set point of current area.
Note that: Set Point Monitor is only used for check set point, but not for modifying. If you want to modify
the set point, enter “Set Point” and input the right password.
Close time:
☆
This is used for monitor the breaker actual close time. It can save ten lately actual close time of breaker.
The time measuring is only for breakers that need “fast switch” and “synchronization” operation. The
principle is to measure the current that gets through beaker. The course of breaker status changes from open
to close is a course that current changes from zero to live. Because there is pre-breakdown transient in close
process of breaker and zero-excursion in measure circuit, and the detected object is AC value of protection
circuit, the actual arithmetic is not simply detected if there is current or not. In order to obtain ideal measure
value, the device adopts fuzzy theory to analyze the sampling value of current and furthest eliminate the
noise. In most occasions, the precision reaches within ±2 ms, and this is enough for “fast transfer” and
“synchronization”. Because some excursion exists in breaker close time, ten lately historical records are
provided to be the foundation of setting related set point for users.
6.5 Set Point instruction
Choose “Set Point” in main menu, press “Enter”, and input right password (the ex-factory password is 0000 and
you can set new password as you like) to enter “Set Point” page. There are three setting contents in the page,

Scheme 6：Double backup supplies switch control
Scheme is shown as in Figure 67:
Figure 67 Main connection
Control logic：
Characteristics:
If the status of the external input value mode 1 and mode 2 are different, the work supply is incomer 1, backup
supply is determined by mode selection status. When mode 1 closed, mode 2 tripped, incomer 2 is the backup
supply; When mode 2 closed, mode 1 tripped, incomer 3 is the backup supply.
If the status of the external input value mode 1 and mode 2 are same, the close sequence of backup supply is
determined by quality of the voltage, the priority level of the voltage from high to low is：incomer 1，incomer 2，
incomer 3，the principle of backup switch is as follows:

2DL closed, 1DL and 3DL tripped, bus energized by supply 2 through 2DL, supply 1 and 3 is used for backup
(supply 1 is primary backup, 3 is secondary back up, 1 take precedence over 3, only valid if bi-direction transfer
be selected); bus energized by supply 2 through 2DL, supply 3 is used for backup (Only valid if single direction
transfer be selected).
When mode 1 closed, mode 2 tripped:
1DL closed, 2DL and 3DL tripped, bus energized by supply 1 through 1DL, supply 2 is used for backup;
2DL closed, 1DL and 3DL tripped, bus energized by supply 2 through 2DL, supply 1 is used for backup (Only
valid if bi-direction transfer be selected).
When mode 2 closed, mode 1 tripped:
1DL closed, 2DL and 3DL tripped, bus energized by supply 1 through 1DL, supply 3 is used for backup;
3DL closed, 1DL and 2DL tripped, bus energized by supply 3 through 3DL, supply 1 is used for backup (Only
valid if bi-direction transfer be selected).
Device energized, if the voltage of bus and any backup supplies are qualified, the device begin to charge 10 s,
then system enter fault monitor state.
Manual transfer logic (e.g. series transfer mode):
When mode 1 and mode 2 are both closed or tripped:
① When 1DL closed, 2DL and 3DL tripped, device is ready for a manual switch. If manual switch signal
presence, trip 1DL, close backup supply according to backup close principle;
② When 2DL closed, 1DL and 3DL tripped, device is ready for a manual switch. If manual switch signal
presence, trip 2DL, and close backup supply according to backup close principle;
③ When 3DL closed, 1DL and 2DL tripped, device is ready for a manual switch. If manual switch signal
presence, trip 3DL, and close backup supply according to backup close principle.
When mode 1 closed, mode 2 tripped:
① When 1DL closed, 2DL and 3DL tripped, the voltage of incomer 2 is qualified, device is ready for a manual
switch. If manual switch signal presence, trip 1DL and close 2DL;
② When 2DL closed, 1DL and 3DL tripped, the voltage of incomer 1 is qualified, device is ready for a manual
switch. If manual switch signal presence, trip 2DL and close 1DL.
When mode 2 closed, mode 1 tripped:
① When 1DL closed, 2DL and 3DL tripped, the voltage of incomer 3 is qualified, device is ready for a manual
switch. If manual switch signal presence, trip 1DL and close 3DL;

② When 3DL closed, 1DL and 2DL tripped, the voltage of incomer 1 is qualified, device is ready for a manual
switch. If manual switch signal presence, trip 3DL and close 1DL.
After manual switch, device will return to normal operating mode.
Accident switch (e.g. series switch mode):
When bus voltage loss or breaker mis-trip, device is ready for an accident switch, the logic as follow:
When mode 1 and mode 2 are both closed or tripped:
① 1DL closed, 2DL and 3DL tripped, when bus is voltage loss or 1DL mis-tripped, trip 1DL, close backup
supply according to backup close principle;
② 2DL closed, 1DL and 3DL tripped, when bus is voltage loss or 2DL mis-tripped, trip 2DL. If bi-direction
transfer is effective, close backup supply according to backup close principle. If single direction transfer is
effective, close backup supply according to backup close principle.
When mode 1 closed, mode 2 tripped:
① 1DL closed, 2DL and 3DL tripped, when bus is voltage loss or 1DL mis-tripped, if the voltage of incomer 2
is qualified, trip 1DL and close 2DL;
② 2DL closed, 1DL and 3DL tripped, when bus is voltage loss or 2DL mis-tripped, if the voltage of incomer 1
is qualified, trip 2DL and close 1DL. (Only valid if bi-direction transfer be selected)
When mode 2 closed, mode 1 tripped:
① 1DL closed, 2DL and 3DL tripped, when bus is voltage loss or 1DL mis-tripped, if the voltage of incomer 3
is qualified, trip 1DL and close 1DL;
② 3DL closed, 1DL and 2DL tripped, when bus is voltage loss or 3DL mis-tripped, if the voltage of incomer 1
is qualified, trip 3DL and close 1DL. (Only valid if bi-direction transfer be selected)
Fault switch (e.g. series switch mode):
After the device charged, if incomer faults presence, the fault incomer will execute fault switch. The logic as
follow:
When mode 1 and mode 2 are both closed or tripped:
① 1DL closed, 2DL and 3DL tripped, if incomer 1 faults, trip 1DL, close backup supply according to backup
close principle;
② 2DL closed, 1DL and 3DL tripped, if incomer 2 faults, trip 2 DL, if bi-direction transfer is effective, close
backup supply according to backup close principle. If single direction transfer is effective, close backup supply
according to backup close principle.
When mode 1 closed, mode 2 tripped:
