基于電容器跟蹤投切的無功補償裝置控制分析

摘要：隨著電力電子技術的迅速發展，電力系統中無功功率損耗問題日益突出。為保證系統或者電網的安全、優質運行，必須對電力系統的無功補償問題進行深入研究。本文主要討論了投切電容器的無功功率補償裝置的控制系統，重點分析了晶閘管投切電容器（TSC）的控制原理，最后結合實例論述了G(X)D1型電容器跟蹤投切柜（箱）及其控制器。 敘詞：無功補償 投切 控制器 電容器 Abstract：With the quick development of power electronics technique,the question of Var power loss in electricity system is more and more serious.It is essential to research the questions of Var power compensation to meet system’s safe and qualitative operationThis paper mainly discuss controlled system of Var power Compensator Whose capacitors are switched,and analyse control principle of Thyristor Switched Capacitor(TSC),and discuss G(X)D1Switched Capacitor Cabinet(Box) and control appliance connect with an example at last.
