An dynamic Var Compensation Filter Based on DSP and Thyristor in Low Voltage Power System

晶闸管具有导通速度快的特点,采用晶闸管投切电容器、电抗器组成的单调谐滤波器,可以相当快的速度无冲击投切,用来补偿无功变化大、变化频繁的场合。由于DSP技术的发展,计算的速度和精度不断提高,实时跟踪计算电网的无功功率已不成问题。本文介绍了一种基于DSP和晶闸管投切的低压动态无功补偿装置的实现方法。

Thyristor can conduct in several microseconds,so the filter constructed with thyristor,capacity and inductance can be switched in real time.With the development of the DSP technology,DSP processing ability is enough for tracing the reactive power of the power system.This article introduces a method of dynamic Var compensate in low voltage power system using DSP and thyristor.
