摘 要
晶閘管控制電抗器(TCR)型靜止無功補償裝置(SVC)由于其對快速波動負荷補償的良好效果，成為近年來無功補償的熱點。
本設計對SVC的各種裝置進行了比較，分析了FC-TCR型SVC的原理以及控制方法，并在此基礎上設計了以AT89S54單片機為核心的動態無功補償裝置的控制器�？刂齐娐分饕�由交流采樣單元、外部擴展單元、顯示單元以及控制單元等組成，硬件緊湊，控制簡單。裝置能對電網參數進行實時監測，對系統無功實行跟蹤補償。

關鍵詞:晶閘管控制電抗器，AT89S54單片機，無功補償

Abstract
Static Var Compensator(SVC) based on Thyristor Controlled Reactor(TCR)has good compensation-perofrmance for rapid changing load, so it has become a hotspot in recent years.
In this paper、all equipments of the SVS family is introduced, the working principle and control on FC-TCR is searched,Based on this theory , a dynamic Var compensator controller is designed with AT89S54 microcomputer.Control circuit mainly include the exchange of sampling unit, the external expansion unit, display units, the control unit and other components, compact hardware, Programming easy, simple control. The device to real-time detection of network parameters, the system implemented tracking reactive compensation.
