6 FAQs about [Photovoltaic power station inverter identification]

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.

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.

What is a line resistance R in a PV inverter?

The line resistance r is connected to the output end of the PV array to simulate the equivalent impedance of the actual array collection circuit. Table 4. Main parameters of the PV inverter In Fig. 8, a comparison of the test results and simulation results under the voltage dip conditions of 0 pu H, 0 pu L, 0.35 pu H, and 0.20 pu H were made.

How can LVRT test be used to identify a PV system?

To simplify the test items and steps needed for parameter identification, an appropriate identification and modelling method for a PV generation system is proposed on the basis of an LVRT test. This LVRT field test is conducted on a large PV system in North China. The three groups of parameters are identified with the test data.
