6 FAQs about [Normal parameter representation of photovoltaic inverter]
What are the reference values for a PV inverter?
The reference values of the active and reactive currents can be expressed as follows: PDC−VDC curves with r = 0 Ω and r = 0.042 Ω, respectively. In the failure mode, the PV inverter operates at point G1 (actual operating point) when r = 0.042 Ω, and the DC voltage rises by 111 V.
How does R affect the DC voltage of a PV inverter?
The PV inverter operates at G 2 when r = 0 Ω, and the DC voltage rises by 98 V. A noticeable difference of 11.7% exists between the two operating points. Therefore, the influence of r should be considered in the LVRT process to accurately model the dynamic behaviours of the DC voltage.
Can LVRT test identify the parameters of a PV inverter?
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.
What is the operating condition of a PV inverter?
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.
How does a PV inverter work in failure mode?
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. The PV inverter operates at G 2 when r = 0 Ω, and the DC voltage rises by 98 V. A noticeable difference of 11.7% exists between the two operating points.
