6 FAQs about [The corresponding line colors of p1p2p3 on the photovoltaic inverter]

How can a photovoltaic inverter influence background harmonic characteristics?

Taking the typical grid symmetrical harmonic −5th, +7th, −11th and + 13th order harmonic as an example, the impedance network and the definition of harmonic amplification coefficient can be used to analyze the influence of photovoltaic inverter on the corresponding background harmonic characteristics.

How a PV Grid connected inverter generates output harmonics?

The output harmonics of the PV grid-connected inverter are generated under the action of grid voltage harmonics, resulting in corresponding harmonics of its output current. The fundamental reason is that the output harmonics of the inverter are generated by the excitation of harmonic voltage source.

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.

Why does PV inverter output voltage contain high order harmonics?

According to the previous analysis, the increase of the PV inverter output power may cause PV output voltage to contain high order harmonics under the weak grid, which are mainly distributed near the resonance peak of output filter LCL of PV inverter.

Does a photovoltaic inverter have a harmonic absorption ability?

This indicates that the photovoltaic inverter itself has no harmonic voltage absorption ability and will output the corresponding harmonic current under the action of the harmonic voltage source of the power grid. Fig. 14. Amplification coefficient of PCC under background harmonic.
