虚拟同步机参考文献
- 随着环境污染问题和能源危机的加剧,越来越多的分布式电源接入电网,而大量的分布式电源接入传统电网会使电网输入和输出功率不匹配,从而造成频率和电压幅值波动严重,威胁了电网电压的稳定。 问题:电流源并网孤岛运行和电压支撑能力差,短时过载能力弱,转动惯量小。(电压支撑能力、故障恢复能力、频率稳定性) 为维持电网输入输出功率平衡及频率稳定,一些学者提出了虚拟同步电机(Virtual Synchronous Generator,VSG)的概念,以增大系统惯性,增强系统的电压频率和幅值的支撑能力。(Wit

- 有源电力滤波器(APF:Active power filter)是一种用于动态抑制谐波、补偿无功的新型电力电子装置,它能够对不同大小和频率的谐波进行快速跟踪补偿,之所以称为有源,是相对于无源LC滤波器,只能被动吸收固定频率与大小的谐波而言,APF可以通过采样负载电流并进行各次谐波和无功的分离,控制并主动输出电流的大小、频率和相位,并且快速响应,抵消负载中相应电流,实现了动态跟踪补偿,而且可以既补谐波又补无功和不平衡。(APF:Active power filter))
