介绍了几种常见无功补偿技术,并对各种补偿种技术的相关特性进行了分析。针对目前广泛应用的静止无功补偿技术(SVC),设计了一种基于DSP的晶闸管投切电容器(TSC)无功补偿装置。应用Matlab/SPS仿真软件,对TSC装置的建模并且对电网在进行功补偿前后的电压、电流和无功的变化情况进行了仿真。仿真结果表明,该装置系统控制策略的正确性并能明显改善电网电能质量。

This paper introduces several common reactive compensation technologies, and analyzes the relevant features of the various compensation techniques. As for the static Var compensation （SVC） technique that is widely used, a SVC device for thyristor switched capacitor （TSC） is designed based on DSP. The Matlah/SPS simulation software is used to set up a model for the TSC device, and simulate the change of voltage, current and reactive power before and after the reactive power compensation of the grid. The simulation results show the correctness of the system control strategy, as well as TSC can significantly improve power quality of the grid.
