台灣民營電廠電力系統穩定器參數調整研究

台電系統在第三迴路345KV輸電線及民營電廠陸續加入營運後，台灣電力系統之特性已大異於以往之系統，且鑒於電力系統有其特定、固有的自然頻率，並依循該等頻率所屬之振盪模式組合，以決定系統受到任何形式干擾後之響應行為，本論文就民營電廠之發電機組裝設之系統穩定器參數進行檢討，並經由調整前述參數，以改善民營電廠發電機機組動態特性。本論文目標首先考慮台灣電力系統96-98年之尖峰及離峰負載系統，檢視民營電廠既有機組穩定器參數適宜性、檢討既設之民營電廠電力系統穩定器適用參數值。並運用頻域及時域分析程式，進行在各運轉狀態下電力系統小信號穩定度特性分析，提供強化台電系統穩定度之可行方案，並且針對補償角度在欠補償及過補償狀況下，作一探討與分析。

After the third loop of 345KV transmission line and Independent power plant (IPP) generation plants are joint operation of Tai wan power system, the characteristics of Taiwan power system will become very different from those of the previous system. At different operation point, the power system has its inherent natural frequency and eigenvalue, which determining the response behavior after the system is suffered any form of perturbation. This thesis will examine the power system stabilizer (PSS) parameter values on the generators which already installed PSS of IPP generation plants, and via adjusting the above parameter values, in order to improve dynamic characteristic of the generators. Therefore, the objective of this project is first to conduct peak-load and off-peak load power system analysis for the year of 2007 and 2009, examine the PSS parameter values on generators which belong to IPP companys, and to study the suitable PSS parameter values. This thesis will use the frequency domain and time domain analysis program to analysis the small signal stability of the Taiwan power system under each different operation condition, and propose the suitable PSS parameter values to enhance the Taiwan power system stability. Final this thesis will analysis the situation of over compensation and under compensation.
