随着现代电力电子设备等非线性负荷大量接入电网,使电网供电质量受到一定影响,其中各种电力电子开关器件的大量应用和负载的频繁波动是最主要的干扰源,导致了一系列不良影响。目前解决这一问题普遍使用的方法是在干扰负荷接入点同时接入静止型动态无功补偿装置,即Static Var Compensator(SVC),用以消除无功冲击,滤除高次谐波, With the modern power electronics and other non-linear load a large number of access to the power grid, the power supply quality is subject to a certain extent, in which a variety of power electronic switching devices and frequent load fluctuations is the main source of interference, leading to a series of bad influences. At present, the commonly used method to solve this problem is to simultaneously access the stationary dynamic reactive power compensation device (Static Var Compensator (SVC)) at the interference load access point, to eliminate reactive impact, filter out higher harmonics,
