虚拟同步发电机频率偏差前馈阻尼控制策略的参数整定方法

open access: yesGaoya dianqi
虚拟同步发电机(virtual synchronous generator,VSG)也存在类似于传统同步发电机的功率振荡特性,频率偏差前馈阻尼方法实现简单,能够有效抑制有功功率指令值或电网频率跳变情况下VSG的有功功率振荡,同时不会影响VSG原有的惯量特性。然而,现有研究在建立频率偏差前馈阻尼方法的有功功率环闭环传递函数模型时未考虑功率低通滤波的影响,系统阶数由3阶变为2阶,若仍采用现有的参数整定方法可能导致前馈系数设计不正确。为此,文中在考虑低通滤波的基础上建立了VSG的传递函数模型 ...
