To step up the output voltage of the inverter to such levels, a transformer is employed at its output. This facilitates further interconnections within the PV system before supplying power to the grid. The paper sets out various parameters associated with such transformers and the key performance indicators to be considered.
In the case that the PV inverter control strategy and parameters are not disclosed, a method is proposed to realise the identification of the three types of parameters through the LVRT test. The method can solve the difficulty in performing the tests of Groups 2 and 3 parameters in the field.
The operating condition of 0.35 pu H is regarded as an example to verify the necessity of the equivalent resistance r. Fig. 5 shows the PDC − VDC curves with r = 0 Ω and r = 0.042 Ω, respectively. In the failure mode, the PV inverter operates at point G 1 (actual operating point) when r = 0.042 Ω, and the DC voltage rises by 111 V.
