山东后村变电站中，大量工业负载引起谐波干扰，导致电能质量严重超标。为了有效解决此问题，通过PSCAD仿真软件等效模拟实际电网系统工况，设计“无源+有源”谐波治理方案，在变电站中压侧安装传统滤波装置及SVG （Static Var Generator---高压动态无功补偿发生装置，或静止同步补偿器）。对比分析治理方案实施前后系统电流的变化，结果表明，滤波补偿装置加装后对系统的各次谐波均有明显的抑制效果。
山東後村變電站中，大量工業負載引起諧波榦擾，導緻電能質量嚴重超標。為瞭有效解決此問題，通過PSCAD倣真軟件等效模擬實際電網繫統工況，設計“無源+有源”諧波治理方案，在變電站中壓側安裝傳統濾波裝置及SVG （Static Var Generator---高壓動態無功補償髮生裝置，或靜止同步補償器）。對比分析治理方案實施前後繫統電流的變化，結果錶明，濾波補償裝置加裝後對繫統的各次諧波均有明顯的抑製效果。

Harmonic disturbances caused by a large number of industrial loads have led to severely poor power quality at Houcun Substation in Shandong. To address this problem effectively,the working conditions of the actual power system is simulated with PSCAD simulation software,and the“passive and active”Harmonic Suppression scheme is designed and the traditional filtering device and SVG(Static Var Generator,high voltage dynamic reactive power compensation device,or Static synchronous compensator)are installed at the medium voltage side of the substation. Through analyzing the system current changes before and after implementation of the scheme,it is shown that filtering compensation devices have obvious inhibi-tory effect on harmonics of the power system.
