6 Frequently Asked Questions about “Photovoltaic inverter series compensation coefficient”
How does a PV inverter affect harmonic amplification in PCC voltage?
With increasing the PV output power, the maximum harmonic amplification coefficient in the low frequency band also grows to 1.228. Meanwhile, with the output power grows, the PV inverter causes harmonic amplification in PCC voltage.
How to calculate harmonic amplification coefficient of photovoltaic inverter connected to PCC?
In order to get closer to the engineering practice, the harmonic amplification coefficient of photovoltaic inverter connected to PCC is calculated by using impedance network solution when the power grid contains background harmonics.
What is a passive impedance network of PV inverter grid-connected system?
Using the output impedance of PV inverters in the positive and negative sequence coordinate system, a passive impedance network of PV inverter grid-connected system is established, and the harmonic voltage amplification coefficient of PCC is enhanced.
How does a solar inverter compensate for irradiation intensity?
The inverter performs partial harmonic current compensation due to the solar irradiation intensity. The value of K under the partial harmonic compensation method is 0.86 (shown in Fig. 8 (a)). The grid current compensates for all harmonics according to a proportionality coefficient of 0.86; however, the THD remains high at 9.56 %.
Do inverter parameters influence harmonic characteristics of PCC in full frequency range?
The harmonic amplifying characteristic curve of PCC in full frequency range is established, and the influence of inverter parameters, reactive power compensation device and distributed transmission line model on harmonic characteristics is deeply analyzed.
How does a solar inverter perform harmonic current compensation?
In Scenario 1 (0.5 - 1.0 seconds), with low solar irradiation intensity, the inverter performs full harmonic current compensation, resulting in both K and K h values of 1. In Scenarios 2 (1.0 - 1.5 s) and 3 (1.5 - 2.0 s), as solar irradiation intensity increases, the inverter performs partial harmonic current compensation.
