摘要

本論文提出一策略，使電力系統全黑時，選擇最佳之電力傳輸（加壓）路徑，來使配置全黑啟動電源之電廠於系統全黑時，供應慣常火力發電機組之輔機啟動電源，同時避免加壓路徑上之輸電線電壓過高與電力供需不匹配之現象，以期提高系統復電效能並縮短全黑時間。
為規劃全黑啟動最佳加壓路徑，本論文應用蟻拓演算法(Ant Colony System, ACS)隨機多點搜尋及快速收斂之特性，尋求出全黑啟動之加壓路徑後，利用電力潮流分析軟體PSS/E來模擬檢討及驗證所搜尋出之加壓路徑，以避免路徑上輸電線電壓過高並確保功率平衡等攸關復電順利之要件。
本論文以IEEE 118-bus系統與台電輸電系統作為實驗對象，經由測試及驗證結果顯示，本論文提出之方法所規劃出的加壓路徑確實可降低復電操作上之風險，提高復電初期全黑啟動之效能，期望能提供電力公司於全黑啟動調度規劃上之參考。

This thesis aims to propose a approach to plan the optimal energizing path for black-start and let the plant with black-start units could supply power to auxiliary equipment of conventional fossil-fueled generating units during black-start period. Besides, the energizing path could avoid the over-voltage status on transmission lines and the power dismatch. The approach is expected to restore the system as soon as possible and shorten the time of blackout.
In order to plan the optimal energizing path between black-start units and power plants, This thesis applies Ant Colony System (ACS) which has merits of random searching and conduct fine-tunning to find the optimal energizing path on power system transmission network during black-start period. Once the energizing path is selected, then it will be simulated by power flow analyzing software PSS/E to review and verify the energizing path to avoid over-voltage on transmission line and ensure power balance.
This thesis simulates the proposed approach on an IEEE 118-bus system and an actual Taipower transmission system network. According to the simulation result, it indicates that the method in searching for the optimal energizing path by applying ACS could exactly reduce the risk of power system restoration operation and improve the efficiency of black-start in the early stage of power system restoration. Further more, this method could be expected to provide for electric power company as reference in planning of black-start dispatching.
