中文摘要

本文提出了一种带宽达10kHz的宽带串联谐波电压补偿器(WSHVC),旨在解决微电网中多个并网逆变器(GCI)引发的谐波问题。通过在公共连接点(PCC)注入补偿电压,实现GCI输出侧的高频阻抗虚拟归零,从而显著提升系统稳定性并实现状态监测。

English Abstract

A wideband series harmonic voltage compensator (WSHVC) with an operating bandwidth of 10 kHz for microgrids with a plurality of grid-connected inverters (GCIs) is proposed. It generates a voltage to compensate for high-frequency harmonic voltage at the point of common coupling (PCC), resulting in a virtually zero high-frequency impedance at the aggregate output of the GCIs and, thus improving syst...
