摘要

隨著電力系統結構的改變、負載成長等因素，電力公司必須例行性地執行電力系統穩定度分析，以及時掌握最新系統狀況、趁早發現問題並採取必要措施。
本論文以臺灣本島電力系統為研究對象，探討數種穩定度分析相關議題，包含系統模型及參數之合理性探討、電力系統偶發事故分析、防止大停電之特殊保護系統規劃與設計、全黑啟動加壓路徑動態模擬及電力系統穩定器分析等。
主要利用PTI (Power Technologies, Inc.)的PSS/E (Power System Simulator for Engineering)來執行系統模型及參數的檢查、穩態電力潮流模擬、暫態穩定度分析、特殊保護系統的模擬分析與全黑啟動加壓路徑動態模擬；以及EPRI(Electric Power Research Institute)的SSSP(Small Signal Stability Analysis Program)來執行電力系統穩定器頻域分析，並利用PSS/E的時域模擬來驗證頻域分析的結果。
本論文從執行系統模型及參數的檢查結果當中歸結出常見的問題與對策，從偶發事故分析當中提出大量模擬技術並發現系統弱點，從全黑啟動加壓路徑動態模擬當中能提出適合的加壓操作程序以避免電壓問題，從電力系統穩定器分析當中建立機組小信號電腦模型以供未來再度分析小信號穩定度時使用。最後，從特殊保護系統的模擬分析當中提出大台北地區特殊保護系統操作表，可當作防止大台北地區發生大停電之參考。

Due to the factors like change of power system structure, growth of load, etc., power companies have to regularly conduct power system stability analysis to timely know the system conditions, find problems and take necessary remedial actions.
This dissertation is intended to target at the power system of Taiwan island and research several power system stability related issues including system model and parameter examination, contingency analysis, SPS (Special Protection Systems) for prevention of blackouts, dynamic simulations for black-start energizing paths and PSS (power system stabilizer) analysis.
To study the issues, PSS/E (Power System Simulator for Engineering) of PTI (Power Technologies, Inc.) was used to perform the system model and parameter examinations, power-flow analysis, transient stability analysis, SPS simulations and dynamic simulations for black-start energizing paths. In addition, SSSP (Small Signal Stability Analysis Program) of EPRI (Electric Power Research Institute) was taken advantaged to do frequency domain simulations for PSS analysis and the frequency domain analysis results was then verified by time domain simulations of PSS/E.
For the results of system model and parameter examinations, some common problems have been found and correspondent solutions are also been presented. For contingency analysis, mass simulation techniques have been addressed and possible security problems are identified. For dynamic simulations of black-start energizing paths, feasible energizing operation procedures have been suggested to prevent voltage problems. For PSS analysis, small signal machine computer models have been built for the future use of small signal stability analysis. Finally, Taipei area SPS look-up tables have been completed for prevention of Taipei area blackouts.
