由於台灣地區地狹人稠，各地輸變電設備興建不易，以致產生之電力系統問題相對複雜；在東部轄區的電力系統為一長條形系統，有電壓偏高及偏低問題，為解決東部轄區目前的問題，本論文擬應用在東部轄區裝設靜態同步補償器（STATCOM）來調整無效電力潮流，以能夠在345kV觀二、明潭∼鳳林兩回線或是161kV楓港∼大武兩回線發生事故時，維持東部轄區內之各變電所電壓維持在運轉範圍內，不會因電壓偏低而造成SPS動作卸載。並結合電力系統模擬程式 PSS/E 及利用Python語法撰寫最佳之STATCOM最佳裝設地點與容量之程式，來得到成本最低且成效較佳之結果。最後分析結果為若要降低事故造成之卸載及過電壓情況，則建議裝置地點與容量為台東200MVA與玉里100MVA或是鹿野200MVA與玉里100MVA。

The issue from power system is comparatively complicated due to limited area and dense population in Taiwan and the difficulties in building up power system installation. Power system in eastern area is designed longitudinally, while with overvoltage and undervoltage problem. In order to solve it, the present thesis is providing STATCOM (Static Synchronous Compensator) building in eastern area to adjust reactive power flow, to be able to keep operation voltage in all eastern area substation and SPS won’t load shedding due to undervoltage when 345kV Da-Guan II、Min-Tan∼Fon-lin 2 line or 161kV Fon-Gon∼Da-Wu 2 lines is tripped. Also with Power System Simulator (PSS/E) and program wrote by python language to learn the optimal area for substation installation and capacity for STATCOM, hence lowest cost and better outcome is achieved. The results of final analysis is in order to reduce load shedding and overvoltage , STATCOM install position is and capacity suggest to TaiDong 100MVA and Yuli 100MVA or Yuli 100MV and Luye 200MVA.
