Test setup: The PGU is connected on the DC-side to a PV-simulator and on the AC-side to an AC-grid simulator.The AC-grid simulator is operated with nominal conditions of voltage of 800 V (phase-to-phase) and 50 Hz unless stated otherwise by the applied test requirement.
The setup is shown in Figure 2. The specific test and measurement devices are stated in Annex 4.
Note:
simulator is operated with nominal conditions of voltage of 800 V (phase-to-phase) and 50 Hz unless stated otherwise by the applied test requirement. The setup is shown in Figure 2. The specific test and measurement devices are stated in Annex 4.
Note: Depending on AC connection terminals provided by the inverter type and the earthing system selected, the neutral conductor of the AC source was not connected for the testing.
Figure 2 – Test setup scheme Measurement method: The requirements, as stated by the applicable standard, for the power quality of the connected grid used for the measurements are fulfilled. A number of measurements is conducted as stated by the applicable standard’s test procedure. The sample rates and aliasing filters are chosen as required by the applicable standard and according to generally recognised knowledge. The results are calculated and averaged as stated by the applicable standard. The measurement uncertainty can be found in Annex 4. Primary power sources (DC): Primary power is provided by a PV simulator. Available power is modified by adapting the short circuit current (Isc) value. Following example shows a PV-curve (Isc = 212,1 A, Uoc = 1382,8 V) simulated according to EN50530.

General product information Description of the power circuit (Figure 4): The input and output are protected by SPDs to Earth. The unit is providing EMI filtering at the PV input and output toward mains. The unit does not provide galvanic separation from input to output (transformerless). The output is switched off redundant by the high power switching bridge and a two relays. This assures that the opening of the output circuit can operate in case of one error. The internal control is redundant built. It consists of Microcontroller master ARM (U101) and slave ARM (U100). The master ARM (U101) which can control the relays by switching signals; measures the voltage, frequency, AC current, DC-injection current, insulation resistance and residual current. In addition it tests the array isolation impedance and the RCMU circuit before each start up. The slave ARM (U100) is user for detecting grid voltage, grid frequency and residual current, also can open the relay, and communicate with Main ARM (U101) each other. The unit provides two relays in series on each phase. When single-fault applied to one relay, an error code will appear on display panel, another redundant relay provides basic insulation maintained between the PV array and the mains. All the relays are tested before start up. Both ARM can open the relays.

Notes on calculations General remarks: RMS-Calculations are performed with a moving window, averaging with full sampling rate, losing one full window at the beginning of the time-series, due to the empty filter. The filter is applied twice to all symmetric components with a window length corresponding to one full respectively a half cycle of the measured mean grid frequency. The average grid frequency over the measured interval is calculated from zero-crossings of the sine function.

The reactive current has reciprocal sign compared to reactive power. This originates from the calculation of reactive power based on multiplication of the complex voltage with the conjugated complex of the current as opposed to the reactive current being calculated by the projection of the complex current phasor to the imaginary axis. Phase angles for active and reactive decomposition The difference of the angles of the complex first order fourier coefficients based on nominal grid frequency (50 Hz) calculated from single phase voltage and current and also from positive, negative and zero sequence values constitutes the phase angles. - Average active power gradient The positive sequence active power is
The difference of the angles of the complex first order fourier coefficients based on nominal grid frequency (50 Hz) calculated from single phase voltage and current and also from positive, negative and zero sequence values constitutes the phase angles. - Average active power gradient The positive sequence active power is integrated from the fault end at t2 until t2 + 5 s. The gradient is started from t2 at zero output power until Pref is reached at tc. So the area made up by the artificial triangle (part of the gradient) and rectangle (part of constant value Pref from tc through t2 + 5 s) is equal to the integrated measured active power. -Page 13 of 238 Report No.: 20TH0456_CEA_2019_0

Central Electricity Authority (Technical Standards for Connectivity to the Grid) Regulations Clause/§ Requirement Remark Verdict B2 (3) The generating station connected to the grid, shall remain connected to the grid when voltage at the interconnection point on any or all phases dips up to the level depicted by the thick lines in the following curve, namely: —
VT : Actual Voltage; Vn: Nominal Voltage—
Provided that during the voltage dip, the supply of reactive power has first priority, while the supply of active power has second priority and the active power preferably be maintained during voltage drops, provided, a reduction in active power within the plant’s design specifications is acceptable and active power be restored to at least 90% of the pre-fault level within 1 sec of restoration of voltage. Full LVRT testing was performed on the SUN2000-215KTL-H0 (800 V) based on IEC 62910, testing for 3-phase, 2-phase and single pahse voltage faults. Tests have been performed on all 3 phase configurations and showed identical behavior. Thus this report only depicts the configuration for asymmetric dips on L2-L3 (for 2-phase voltage faults) or L1 (for single pahse voltage faults).
Note: • The grid fault was simulated at the medium voltage side of the Dy-medium-voltage transformer, the measurement at the low voltage side of the transformer was evaluated. • During a symmetrical grid fault the unit provids reactive current according to Tranmission Code 2007 using a proportional factor (k-factor)
the Dy-medium-voltage transformer, the measurement at the low voltage side of the transformer was evaluated. • During a symmetrical grid fault the unit provids reactive current according to Tranmission Code 2007 using a proportional factor (k-factor) of 2 (ΔIreactive = k·Δu·In), the active current will be limited if needed. In case of asymmetrical faults the control strategy of the acitve and reactive current is the same as in case of symmetrical faults, additionally the reactive current injection is limited to max. 40%In. If the active current / power should be maintained at a certain level during a grid fault, this can be achieved by setting a suitable k-factor (setting range: 0~10) to limit the additional reactive current injection. • The activation threshold of the reactive current injection (grid support) was set to 80%Un as default, paramater is adjustable. • Max. measured settling time of active power after fault clearance (≥ 90% of prefault active power): 1,617 s Note: The tests results show the LVRT capability of the unit, using see also remarkPage 16 of 238 Report No.: 20TH0456_CEA_2019_0
