电能质量问题已经越来越受到人们的重视,电压和频率的稳定是电能质量2个主要的方面,而电网中的无功功率便是影响电压质量下降的诱因,不仅如此,无功还会对用户设备的利用率造成影响。基于此讨论了目前广泛使用的静止无功补偿器(SVC),并进一步详细分析了静止无功发生器(SVG)的工作原理,最后利用MATLAB/Simulink软件对由SVG构成的电网补偿系统进行了仿真验证,取得了良好的效果。 The problem of power quality has been paid more and more attention by people. The stability of voltage and frequency is the two main aspects of power quality. The reactive power in the power grid is the incentive to reduce the voltage quality. Not only that, but also reactive power User equipment utilization impact. Based on this, the currently widely used static var compensator (SVC) is discussed, and the working principle of the SVG is further analyzed in detail. Finally, the compensation system of the grid composed of SVG is implemented using MATLAB / Simulink software Simulation verification, and achieved good results.
