Harmonic Extraction and Inverter Generation Technology of Distribution Network

Inhalt:
A new type of harmonic energy separation device using parallel capacitors in series with reactance is proposed. By utilizing the voltage clamping capability of the battery pack, the harmonic energy is transported to the auxiliary power system through the inverter. By reasonably designing the parameters of the harmonic coupling circuit, most of the harmonic current of the series reactor is shunted to the harmonic absorption device, thereby eliminating the harmonics flowing through the series reactor, effectively reducing the harm of harmonics in the distribution network, and converting to the fundamental frequency energy. This paper uses PSCAD software to establish a model for verification, the simulation result shows the validity of the devices.
