摘要
本論文的主要目的是在於研究民國92、95年台電輸電系統第六輸變電計畫執行時,因路權取得困難而大量使用地下電纜其所造成的電壓上升問題,利用最佳並聯電抗器規劃方法控制離峰時的系統電壓於合理範圍。首先針對未來可能採用的地下電纜型式,分析無載與輕載所造成電壓上升現象,計算系統離峰時所產生的總無效功率,並利用程式模擬找出最佳並聯電抗器安裝匯流排的電壓等級,以符合系統電壓控制與其經濟效益。本論文提出利用線性規劃法以達到最佳並聯電抗器位置規劃,取得最佳的電抗器總量後,參酌電抗器現有市場規格與變電所裝置空間大小,經計算後取得各匯流排電壓等級的最佳單組容量。最後比較基因法則和線性規劃法並聯電抗器最佳值,並驗證基因法則可達到整體並聯電抗器的最佳解。在本論文中也予以研究彈性交流輸電系統中的靜態乏補償器與靜態同步調相器,藉由計算推導改善系統的電壓控制問題,最後以靜態同步調相器安裝於嘉民匯流排,以改善系統事故後穩態電壓控制與機電振盪模式阻尼。
ABSTRACT
The purpose of this dissertation is to study the Taipower transmission and substation project on 2003 and 2006, Due to build site difficulty to obtain of overhead line, and use a large number underground cable to cause overvoltage of load part. We use optimal shunt compensator for control system of offpeak to reasonable voltage range. First we will analysis voltage characteristic for kinds of underground cable on no-load and offpeak load condition, compute all of the charger reactive power of system offpeak, and use programming simulation to find the voltage rank for install the optimal shunt reactor, and to fit in with voltage control and economic effect. This paper to bring up use linear programming and genetic algorithm to achieve the optimal reactive power planning, Thus, after programming simulation to coordination spot price and install space of taipower station substation, and to obtain unity shunt reactor capacity for kinds of voltage rank. Finally to use genetic algorithm to compare, and to demonstrate genetic algorithm can search the solution for globe optimal. The paper also present static var compensator and static synchronous compensator two equipments of flexible AC transmission systems, by means of demonstrate to keep voltage control, and install STATCOM in Chiamin bus to improve lost double circuit contingencies steady state voltage and to supply dynamic damping.
