6 FAQs about [Photovoltaic inverter harmonic test report]

What are the harmonic distortion standards for PV system integration?

During the advancement of the PV system integration requirements into the grid, different harmonic distortion standards are imposed; however, they are similar, excluding EREC G83 and VDE-AR-N4105, which are notably strict in which imposed a THD for PV integration should be less than 3%.

What is LC LTER in PV inverters & PV power plants?

An LC lter is used to attenuate the PWM modulation frequency and its harmonics in the inverter system. Before We understand reasons for harmonics in PV inverters and PV power plants, let us start with some basics of Harmonics.

Why do photo voltaic power plants produce harmonics?

As discussed above, In the PV system, the harmonics can be produced due to the use of inverter, converter, and other power electronic devices. In this context, the Photo voltaic power plants contain several power-electronic devices that produce distortion.

What is the difference between a harmonic and an inverter?

Harmonics are any frequency that exists in the system except the fundamental frequency. In other words, harmonics appear as the distortion on the desirable sinusoidal waveform on power line. An inverter is an electronic device that can transform a direct current (DC) into alternating current (AC) at a given voltage and frequency.

How a harmonic current is produced by a PV or wind plant?

Harmonic currents produced by the PV or Wind plants depends on the type of inverter/converter technology used for DC/AC or AC/DC conversion and its control strategy. The output current is also linked to the harmonics of the voltage at the POC, which depends on the contribution of all the generations and loads connected to the network.

What is a PV inverter?

An inverter is an electronic device that can transform a direct current (DC) into alternating current (AC) at a given voltage and frequency. PV inverters use semiconductor devices to transform the DC power into controlled AC power by using Pulse Width Modulation (PWM) switching.
