SPECIFICATION FOR GRID CONNECT SOLAR GENERATING SYSTEM OF
CAPACITY 10 KWp TO 500 KWp
1.0
FOREWORD:
Government of India is laying great emphasis on reducing the country’s
carbon footprint. In this pursuance, the Hon’ble Prime Minister of India
has on 30th June, 2008 released the National Action Plan for Climate
Change (NAPCC). One of the NAPCC missions is the National Solar
Mission and it aims to increase the share of solar energy in India’s
overall energy mix. Accordingly, Indian Railways accords high priority to
harnessing of solar energy.
The energy generated by grid connect solar photovoltaic system will be
utilized to feed railways’ electrical loads during daytime. As a result,
during daytime, the purchase of electricity from the electricity authority
will get reduced.
2.0
SCOPE:
This specification provides the generic requirement for grid connect
solar photovoltaic (SPV) system capacities in the range 10 KWp to 500
KWp. The user will specify the SPV system’s KWp capacity, after duly
considering the MNRE norms for subsidy, electrical load and availability
of space for installation of SPV modules. In instances where none of the
standard available Power conditioning unit (PCU) KVA ratingsare
commensurate with the purchaser specified KWp of SPV system, in
such case the purchaser can consider accepting the PCU of next higher
standard rating.
The specification covers general and technical requirements for design,
manufacturing, testing, supply, installation and commissioning of Grid
connect solar generating system to be provided at railway premises for
meeting the railway requirements of lighting, ventilation and other
electrical services. The solar photovoltaic generating system’s inverter
will operate in parallel with the general electric supply system on
railway premises.

Spec. no. RDSO/PE/SPEC/PS/0092-2008 (Rev.‘0’),Amdt.-5
4.3
DC distribution board/ combiner shall be provided in between solar
array and PCU. It shall have DC Disconnector/MCCB of suitable rating
for connection and disconnection of array section. Type II Surge
Arrestor should be incorporated for surge protection. It shall have
meters for measuring the array voltage and array current. Appropriate
IP protection shall be provided. In case of string inverters, if the
requirements served by DC distribution board are fully taken care of by
string inverter(s), then firms’ proposal (if any) for elimination of DC
distribution board from the system design, can be considered.
4.4
AC distribution board shall be provided in between PCU and loads. It
shall have an integrated energy meter, voltmeter and ammeter. As for
energy, generally the parameter of interest shall be the aggregate energy
output of inverter(s) fed into the individual AC distribution board(s).
Though not mandatory, firms are however encouraged to also offer the
facility for recording the energy output data of each inverter (wherever
multiple inverters are feeding into an AC distribution board). Class I + II
(as per IEC 62305) 100 kA Surge Arrestor should be incorporated for
protection against surges.
4.5
No electrical storage batteries shall be required and accordingly, these
are not included in the scope of work.
4.6
The system shall comply IEC 60364-7-712 and 62446.
5.0
GENERAL REQUIREMENTS:
5.1
Solar generating system shall supply part/ full load of railway service
buildings/ areas. Thereby, the PV system shall reduce the electric
energy units drawn by railway from the grid and reduce IR’s CO2
emissions.
5.2
Solar panels and array junction boxes shall be installed on shade free
roof while the transformer based PCU and distribution boards, etc. shall
be housed inside the room provided by Railways. In case of string
inverters, railways should carefully weigh the option of indoor vs.
outdoor installation. The installation of SPV modules on roof-tops must
not impact the waterproofing of the existing terrace structure. The
contractor shall be responsible for restoring the waterproofing to its
original condition and for provision of additional waterproofing in the
areas where RCC blocks are secured on to the terrace. Even though
roof-top mounting of solar panels shall be the preferred option, if
necessary, railways can at their option specify a ground mounted solar
system for part or full system KWp capacity. In the event that railways
decide on a ground mounted solar system, they must specifically
mention this in their tender and also specify the fencing requirements
as will be appropriate to the site (ref. item 6 of Annexure - C). For
ground mounted solar systems, railways may need to: carry out site
preparation works (e.g. site levelling, removal of obstructions, etc.); plan
Page 6 of 29
Effective from August 2013
Spec. no. RDSO/PE/SPEC/PS/0092-2008 (Rev.‘0’),Amdt.-5
suitable arrangements for preventing theft, vandalism, etc.; ensure the
availability of adequate railway base load; identify a reliable railway grid
power supply line and be responsible for carrying out any
supplementary works required for feeding the renewable energy into the
identified railway grid power supply line.
5.3
For individual systems above 20KWp, availability of requisite space on a
single roof-top can at times become a constraint. In such case, the
system’s overall KWp capacity can be distributed across multiple rooftops and each of the rooftops shall then feed to the grid power supply
system. In works involving such distributed systems, the purchaser
must mention the KWp of individual constituent solar systems in the
tender (refer item 7 of Annexure - C). If the purchaser doesnot mention
anything against item 7 of Annexure - C, it will be deemed that
adequate space is available on a single rooftop for the entire KWp
capacity of the system.
5.4
If required, statutory approval of local authorities/state electricity
distribution company, etc. shall be obtained by the Railway Authority.
An export meter (for recording the number of units exported to the grid),
if required, shall be either installed by state electricity distribution
company or else the respective Railway Authority may include the same
in their scope of work. Export metering will be an optional item; it will
be specifically mentioned by purchaser, if the same is required to be
within the contractor’s scope of supply (see Annex C item 5). It is
emphasized here, that primary purpose of installing the SPV system
covered by this spec., is to meet railway’s own energy requirement,
rather than supplying renewable energy to the public grid.
5.5
Railway Authority shall provide a shadow free area @ 125 - 150 sq.
ft./KWp of solar array.
5.6
Array structure of PV yard and all electrical equipments such as PCU,
inverters, etc. shall be grounded properly. Towards this end, the
contractor will supply and install an adequate number and appropriate
size of IS:3043 – 1987 compliant earthing kits; at least one each for AC
circuit, DC circuit and lighting protection system.
5.7
Suitable marking shall be provided on the bus for easy identification.
5.8
PV modules may be connected in series up to the maximum allowed
operating voltage of the PV modules and the PV inverter, whichever is
lower.
5.9
The reverse current of blocking diodes (connected in series), if required/
provided, shall be rated for 2 X VOC STC of the PV string.
5.10 Proper sealing arrangements at the points of cables entering the
enclosures/ buildings should be incorporated. Although not mandatory,
Page 7 of 29
Effective from August 2013
Spec. no. RDSO/PE/SPEC/PS/0092-2008 (Rev.‘0’),Amdt.-5
manufacturers are however encouraged that the cables entering into
the enclosures be sealed with modular EPDM based cable sealing and
protection system based on multi-diameter technology.

INTEGRATED RENEWABLE ENERGY BASED POWER SUPPLY
ARRANGEMENT
1.0
FOREWORD:
The Wind and Sun are inexhaustible, reliable and non-polluting sources of
power. Keeping in view the rising concerns over climate change and depleting
reserves of petroleum and coal, it is important to integrate these renewable
energy systems into the existing electricity supply. For locations where the
availability and quality of grid electricity supply is poor, integration of solar or
wind-solar systems (with battery back-up) with the grid supply system can
help to ensure uninterrupted availability of electricity for electrical services at
railway stations, railway offices, etc. with minimal or nil dependence on DG
sets.
2.0
SCOPE:
This specification covers the general and technical requirements of integrated
renewable energy (solar/ wind-solar) based power supply for railway stations,
railway offices, etc. The system covered by this specification encompasses
Wind Turbine (WT), Solar Photovoltaic modules (SPV), Solar Charge
Controller (SCC), Wind Charge Controller (WCC), Grid-synchronizing Invertercum-Charger and Battery. At sites having annual average wind speed of 4.17
m/s or above (at 20m height), wind-solar hybrid systems can be considered.
But at sites which do not meet the aforesaid wind speed criterion, a SPV only
system should be specified by the purchaser (Refer Item 1.2 of Annexure-2).

6.0
TECHNICAL REQUIREMENTS:
6.1
System design, ratio of wind-solar energy and system sizing
6.1.1 System design
The system will be designed to preferentially utilize renewable energy for
supplying the essential general electrical loads and charging the battery. But
when the battery gets discharged beyond a point, it will be possible to charge
Page 6 of 35
Effective from October 2012
Spec No. RDSO/2009/EM/SPEC/0004 (Rev.‘1’) - 2012
the battery from grid electricity supply or else, in the event of grid supply
outage, the system should be able to automatically start the DG set through
potential free contact and utilizing AMF panel of DG set. The system will
include a grid-synchronizing Inverter which will receive DC input from SCC/
WCC with Battery floated across the DC bus and deliver AC output for feeding
the essential general electrical loads at railway stations, offices, etc. When the
battery is in a fully charged state, the SCC and WCC will feed entirely to the
Inverter and feed excess available power to the grid, if any; else, the SCC and
WCC will charge the battery and any remnant excess power will be fed to the
Inverter to supply other electrical loads/grid. The Inverter will be capable of bidirectional power flow so that it can also function as a charger. The Inverter
should be capable of operating in parallel with the local grid power supply
during excess energy grid feed mode. Thereby, under heavy load conditions,
any balance power requirement over and above that available from the
Inverter, can be fed by grid power supply. Also, during the time period when
the station or office load is low, it should be possible to set up/ program the
system to export any surplus renewable energy.
6.1.2 Ratio of wind-solar energy and sizing of the system
In specifying the system, ratio of wind and solar energy should be decided in
a manner that is economically beneficial to railways; in this regard, the MNRE
norms for subsidy should also be taken into account. Sizing of SPV, WT,
SCC, WCC, Inverter-cum-Charger, Battery, etc. will depend on the system
load to be catered and the required autonomy. From economy considerations,
it is recommended that sizing of the system should take into account only the
most essential loads and two days (24-hrs) autonomy. In laying down the
aforesaid autonomy, it has been presumed that the railway station/ office is
equipped with grid electricity supply and a DG set. But if local conditions
require so, the purchaser can size the system for an autonomy higher than
24-hrs. The purchaser must mention his specific requirements as per
performa provided in Annexure-2 of this spec (Refer Item 5.2 in Annexure-2).
6.2
Wind Turbine (WT)
6.2.1 The WT must have undergone IEC 61400-12-1 type testing for power
performance measurement and IEC 61400-2 type testing for safety from an
accredited test house such as Govt of India’s Centre for Wind Energy
Technology (CWET), NREL, etc. Further, the offered WT should also have
regular empanelment from CWET (Refer Item 2.1 of Annexure-2).
6.2.2 All exposed/external parts of WT shall be suitably coated for prevention of
corrosion in harsh marine environment. Although it is being kept optional (at
the choice of purchaser) for now, manufacturers however are encouraged to
get the WT type tested for salt spray test as per ASTM B-117 for a minimum
period of 1,000 hours, if they have not already done so. In case of bulk
tenders, zonal railways can consider specifying that the contractor furnish this
type test certificate (Refer Item 2.2 of Annexure-2).
Page 7 of 35
Effective from October 2012
Spec No. RDSO/2009/EM/SPEC/0004 (Rev.‘1’) - 2012
6.2.3 The manufacturer will need to furnish evidence that the WT being supplied is
the same as the one type tested as per IEC 61400-12-1 and IEC 61400-2.
Although it is not being made mandatory for now, manufacturers however are
encouraged to create the necessary testing infrastructure for enabling the
purchaser to verify the IEC 61400-12-1 certified power (watts) vs. rotational
speed (RPM) in steps of 100 RPM, prior to dispatch.
6.2.4 Suitable protection such as furling mechanism, pitch control of blades or
electromagnetic braking shall be provided for protection of WT against high
velocity wind, storms and over-speeding.
6.2.5 The WT shall be able to withstand wind speeds of 55 m/sec or 198 kmph.
6.2.6 Mounting Towers shall be of 15 meter height and made of hot dip galvanized
mild steel. Galvanization thickness shall be of min. 85μm. If the systems are
installed in coastal/ corrosive areas, the minimum galvanization thickness
shall be 120μm. Unless the purchaser has specifically asked for 120 μm
thickness, normally 85 μm will be supplied. The turbine hub height shall be at
least 5 meter above any obstruction within 200 meter radius. If at certain
locations, tower height more than 15 m is required, then the same must be
especially mentioned in the tender schedule. The tower has to be designed to
withstand a minimum wind speed of 55 m/s or 198 kmph (Refer Items 1.3 &
2.3 of Annexure-2).
6.2.7 WT shall be grounded properly. Towards this end, the contractor will supply
and install an adequate number and size of IS: 3043-1987 compliant earthing
kits.
6.3
SPV Modules and related items
6.3.1 Solar panels and array junction boxes shall be installed on shade free roof
while the PCU and distribution boards, etc. shall be housed indoors in the
space to be provided by Railways.
6.3.2 The SPV panel shall have a provision for angular adjustment of the mounting
structure to get maximum utilization of incident sunlight. It shall be mounted
facing south and tilted to an angle equal to the latitude where being used, for
optimum performance.
6.3.3 Railway Authority shall provide a shadow free area @ 125 - 150 sq. ft./ KWp
of solar array.
6.3.4 Array structure of PV yard and all electrical equipments such as PCU,
inverters, etc. shall be grounded properly. Towards this end, the contractor will
supply and install an adequate number and appropriate size of IS: 3043-1987
compliant earthing kits; at least one each for AC circuit, DC circuit and
