摘要

本論文之主要目的在探討利用虛虛功補償器：靜態乏補償器（Static Var Compensator，SVC）與靜態同步補償器（Synchronous Static Var Compensator，STATCOM）等補償裝置改善台電系統在第一、第二、第三輸電迴路重要匯流排的電壓動態特性。
因為在目前台電系統中，存在兩個主要問題：峨眉匯流排電壓過低之狀況與中寮南三相接地故障對重要匯流排在故障清除後劇烈的電壓振盪。
本研究中將探討利用虛虛功補償器改善峨眉匯流排電壓過低的狀況。為抑制中寮南三相接地故障過大的電壓振盪，本論文以PSS/E-29（Power System Simulator for Engineering）使用者手冊建議之方式調整後，選定虛虛功補償器控制器參數，並評估其對電力系統中的各匯流排電壓振盪的抑制能力。
研究結果顯示，靜態同步補償器改善穩態峨眉低電壓的效能較強，而靜態乏補償器則因加入輔助調變控制器（ Supplementary Modulation Controller，SMC ）在動態的電壓振盪抑制方面略勝一籌。

The main purpose of this thesis is to study the application of the compensation devices such as Static Var Compensator (SVC), and Static Synchronous Compensator (STATCOM) to improve the dynamic voltage characteristics of Taiwan power system.
In daily operation of Taiwan power system, two problems have been observed. One is the low bus voltage on Omei substation; and the other is the severe voltage oscillation on important substations after a three phase bus fault at the Chungliao South bus.
In this thesis, improvement of the low bus voltage on Omei substation with the two types of reactive power compensators will be discussed. Moreover, to suppress acute oscillation following a three phase fault at the Chungliao South bus, the damping ability of reactive power compensators will be investigated.
It is found that STATCOM has better performance on improvement of low bus voltage at Omei and SVC performs better in suppressing dynamic voltage oscillation.
