工作停電為配電系統擴充或維修的常態性工作,而停電規劃之良莠攸關供電服務品質的好壞。工作停電規劃是針對各個工作區域安排適當之停電工作時程及工作團隊,其本質上屬於離散性之多目標問題。在工作停電規劃時務必使非工作區之負載能夠維持正常供電,因此,適宜之負載轉供策略必須配合工作停電規劃同時求出。本論文以進化演算法為基礎並結合啟示性規則來提高求解效率,而進化演算法則以實數編碼且採用「單點式突變」之交配方式進行求解。
本論文主要研究範圍包括計劃性之工作停電派工及其負載轉供之開關切換規劃,而停電派工則是考慮多區域、多工作隊並於限定日期內完工,其限制條件包括工作隊資源量、工作時間量;而開關切換之規劃則考慮在放射狀架構之下配電系統不會發生不必要的停電,負載切換時的電壓降限制條件則利用負載潮流程式予以驗證。

本論文以台電鳳山區處OMS資料庫的部分配電系統為對象來進行模擬驗証,由模擬結果可以得知所提出的方法有一定的效能,可以提供台電公司作為具高度參考價值之規劃方案。
The intelligent strategy proposed in this thesis for the outage scheduling of distribution systems is based on the evolutionary approach of genetic algorithm (GA). With integration of heuristic rules in the GA, the proposed approach performs effectively. Constraints considered in the work include limited resource of the crews, limited days to finish the works, and the engineering limits of distribution system such as radial structure of distribution feeders and feeder rating of current limits and limits of voltage drops. Inter-feeder load transfer is important during the outage scheduling due to avoiding unnecessary interruption in the optimal sequence of switching operation associated with the scheduling. Load flow is used to verify the voltage and current limits in this thesis.
Parts of the OMS database of the distribution system in FunSun District are selected for the computer simulation. From the results of the simulation, highly reliable scheduling can be obtained effectively. It is valuable to introduce the approach developed in this thesis to Taipower for their outage scheduling
