Only authorised electricians who are approved by the supply grid operator may open, install and maintain the inverter. ›› Keep all doors and covers closed when the unit is in operation. ›› Do not touch the lines and terminals when switching the unit on and off! 5.6.1 Operating states The Inverter has seven operating states. The explanations about each state are below. Disconnected (default) Before operation has commenced the inverter is in the disconnected state. In this state, the inverter is totally isolated from the PV array and the utility grid. Connecting to the PV array When the inverter is in the “Disconnected” state, the ‘Inverter On’ button on the GUI is selected and the PV voltage is kept above 400V for 5 seconds, the system turns on the PV Array side contactor (PV_MC). Connecting to Grid When the inverter is in the “Connecting to PV Array” state and the PV voltage is kept above the value of “MPPT V Start” parameter during the time set by “MPPT T start” parameter, the contactor on the grid side is turned on. The inverter keeps this state for 8 seconds. Initializing MPP The inverter calculates the MPPT start voltage which is product of measurement of PV voltage and the parameter “MPP Factor”. After 5 seconds, the inverter system enters into the “MPP start” state. Table 3: Operating states Page 28 Operating Instructions Powador XP500/550-HV-TL Sto rag e/In st allat ion/St ar t -up MPP start In this state, the inverter controls the PV voltage. Reference of the PV voltage is determined by MPPT start voltage which is calculated at “Initializing MPP” state. MPPT If the PV voltage approximates the MPP start voltage (value of “MPPT V Start” parameter), the MPPT will start. The inverter follows the MPP target value automatically, which is varied by irradiance values. If the MPP target value is out of the allowable MPPT range ([MPP start voltage - MPP Range lower] ~ [MPP start voltage + MPP range upper]), the system will return to the “Initializing MPP” state and will recalculate the MPPT start voltage. System stop (Disconnected) When the “OFF” button in the GUI is selected, the PV Array side contactor and the Grid side contactor are turned off and the system stops. If the output power of inverter is kept below value of “MPPT P stop” parameter during time of “MPPT T stop” parameter, connection to the grid is terminated. Fault If a fault occurs during operation, the system stops. The system resets the fault and tries to remove the fault. In the case that system removes a fault successfully, system restarts all by itself. The system tries to remove the fault at intervals of “MPPT Start” parameter since the last try until trial count reaches to the number set in an “Auto Fault Reset Count” parameter. After the number reaches to the “Auto Fault Reset Count” parameter, the system will log an error and the system will not try to restart.

If the Anti-Islanding function is not activated, XP-HV and XP-TL cannot disconnect itself from the grid during grid failure, and generate power to load independently. For example, when inverter infuse 500kW power to gird with 500kW load connected to PCC (Point of Common Coupling), inverter can generate output voltage independently during grid failure, and operate itself with bearing 500kW load. 8.7.2 Power Derating Figure 56: Block Diagram of Power Derating Page 76 Operating Instructions Powador XP500/550-HV-TL Param eter s Figure 57: Decreasing rate Figure 58: State Machine Power derating is enabled or disabled by an output of state machine which is decided by 4 inputs. And while the output of state machine is 1, a decreasing rate affects an output power. A decreasing rate is calculated by multiplying factor K({Power Derating P Gain}) and a difference between reference temperature({Power Derating Reference Temperature}) and PEBB heatsink temperature}. An output of state machine depends on the state in which state machine is running. A transfer between states happens when defined conditions are satisfied. Basically, if {Power Derating Enable} is 0, the state is “Disable”. And If {Power Derating Enable} is 1, transfer is done according to PEBB heatsink temperature. Following examples show power derating by default parameter. Descriptions for sections of Example of Power Derating are: T1: Inverter produces energy and PEBB temperature rises. T2: When PEBB temperature is higher than 90°C, power derating is activated. And inverter controls output power according to expression, P(%) = 100 -(TPEBB -80)x2 until power derating is deactivated. T3: Output power decrease and PEBB temperature drops. When PEBB temperature is lower than 70°C, power derating is deactivated. And inverter doesn’t decrease output power.

Here are the communication methods between each component. 1. 2. 3. 4. 5. User activates COSPHI Control by Prolog. Prolog sends a COSPHI Control massage at two-minute intervals. MMI interprets the COSPHI Control message from Prolog to modify parameters of XCU. XCU operates according to the modified parameter by MMI. COSPHI (limited to Fixed COSPHI and Fixed Q) has two overlapping parameters for RPC and Internal modes, and MMI modifies the parameter for RPC mode only. If the relative RPC mode parameter is not modified longer than five minutes, XCU will operate according to the parameter for internal mode. Page 80 Operating Instructions Powador XP500/550-HV-TL Param eter s Figure 62: The communication Sequence between COSPHI Components Operating Instructions Powador XP500/550-HV-TL Page 81 Parameters 8.7.8 Operation Mode COSPHI Control operates in RPC (Remote Power Control) and internal modes according to communication status to control power with Fixed COSPHI and Fixed Q. Figure 63: Transition of RPC mode and Internal Mode 1. RPC mode While MMI is modifying XCU’s {Remote Power Control}, {COSPHI RPC Reactive Power} and {COSPHI RPC Power Factor} parameters with two-minute interval, COSPHI Control operates in RPC mode. In RPC mode, it operates according to {Remote Power Control}, {COSPHI RPC Reactive Power}, and {COSPHI RPC Power Factor} modes. 2. Internal mode If RPC mode parameter such as {Remote Power Control}, {COSPHI RPC Reactive Power}, and {COSPHI RPC Power Factor} is not be modified within five minutes, XCU will operate in Internal mode. In Internal mode, COSPHI control operates according to internal mode parameters such as {COSPHI Internal Reactive Power} and {COSPHI Internal Power Factor}, {Remote Power Control} parameter does not influence on the active power. Figure 64: PQ Diagram of XP500-HV-TL Page 82 Operating Instructions Powador XP500/550-HV-TL Param eter s Output power limit is based on apparent power which is 111% of the rated power. In other words, where the apparent power is over the rated power, active/reactive power is reduced at same rate respectively so that the final output power does not exceed 111% of the rated power. PQ diagram above shows that the reactive power is from 0 to 242kVAR according to the power factor which is from 1 to 0.9, the active power is up to 500kW and active/reactive power is not limited because the final output apparent power is not over 555kVA(111% of the rated power). And because the apparent power is over 555kVA where power factor is less than 0.9 the active/reactive power is reduced. Figure 65: PQ Diagram of XP550-HV-TL Output power limit is based on apparent power which is 101% of the rated power. In other words, where the apparent power is over the rated power caused by reducing power factor, active/reactive power is reduced at same rate respectively so that the final output power does not exceed 101% of the rated power. When changing the power factor from 1 to 0.9, the active power is down to 500kW and the reactive power will be up from 0 to 242kVAR since the final output apparent power should be remained at 555kVA (101% of rated power). In case of power factor is 1.0, the output power is 550kW (550kVA). Operating Instructions Powador XP500/550-HV-TL Page 83 Parameters 8.7.9 The Relationship of Reactive Power and Active Power While active and reactive power is set to exceed maximum complex power (1.11PRated) by parameter setting, COSPHI Control reduces active power, and control reactive power by parameter setting. 8.7.10 Cosφ (P/Pn) The Cosφ (P/Pn) function allows inverter to send changeable PF (power factor) according to the active power to grid. The maximum setup point of both PF and active power is 10 points and the maximum required value of PF for Cosφ (P/Pn) is 0.9 in German market. XP-HV and XP-TL series can also operate with maximum PF, which is 0.9, and its transient time is 10sec.

Operating Instructions Powador XP500/550-HV-TL Page 85 Parameters Section 1 • If Grid Voltage drops below standard FRT value (0.9P.U) set by parameter, inverter will convert its mode to FRT. • The occurrence of Over Current is decided by the slope and depth, and if when over current occurs, inverter will stop PWM Modulation for one cycle. • Inverter will infuse the reactive power to grid according to parameter setting. • Since the reactive power value is proportional to the parameter setting value, you can infuse reactive power to grid as much as possible. Section 2 • Infuse active power and reactive power to grid according to parameter setting. Section 3 • The occurrence of Over Current is decided by the slope and depth, and if when over current occurs, inverter will stop PWM Modulation for one cycle. • Infuse active power and reactive power to grid according to parameter setting. Section 4 • If Grid voltage rises above standard FRT value (0.9P.U) set by parameter, inverter will convert its mode to normal and stop reactive current infusion. The operation for FRT (Fault Ride Through) control is possible to set by parameter as follows. • Grid Under Voltage Levels - Grid Under Voltage Level 1 – Transfer to FRT mode. - Grid Under Voltage Level 2 – Inverter stops its operation with ‘Grid Under Voltage Level 2 Fault’ when the grid voltage below ‘Grid Under Voltage Level 2’ sustains over “Grid Under Voltage Trip Time 2”. - Grid Under Voltage Trip Time 1 – Permissible grid voltage under ‘Grid under Voltage Level 1’ time. - Grid Under Voltage Trip Time 2 – Permissible grid voltage under ‘Grid Under Voltage Level 2’ time. Figure 70: FRT Parameters Page 86 Operating Instructions Powador XP500/550-HV-TL Param eter s 8.7.12 Q(V) Control Figure 71: Grid Voltage Control during Q(V) Control Enable As you can see in the above picture, this Q(V) Control function is for the reactive power infusion even if grid is in normal range (90 ~ 110%). Dead band rage is UTarget±1%. Here, you can calculate slope K Factor for Q(U) Control using an equation ΔQ/ΔU=K Factor, and the variables which are ΔQ=cos(Phi)=0.95, Phi=18.2° and sin(Phi)=0.31. ΔU is the voltage difference between the measured voltage and the specified parameter target voltage as a p.u. Therefore, you can decide slope k factor. For example, if you want to infuse ΔQ at UTarget±5% range and UTarget=UN, the K value would be calculated as 0.31/0.05=6.2. The rage of ΔU is calculated from the end of the dead band.
