臺北捷運因應松山線通車電力轉供探討

摘要

捷運松山線通車前原供給松山線用電之松湖超高壓變電所未能如期完工，當時松山線松
捷主變電站面臨台電供電與不供電的疑問中。本文將說明因應台電供電松捷主變電站不確定
下，透過交流負載潮流分析，總共考量3種供電應對方式，1.原契約供電規劃模式下台電松
湖變電所順利興建完成供電，2.松湖變電所未興建完成松捷未送電模式，3.松湖變電所未興
建完成，但由其他台電變電所供給松捷用電模式。供電模式的變更主要先確保在供電系統正
常（Normal）及非正常（Abnormal）之運轉狀態下，可正常營運，這需經由交流負載潮流
分析確認供電系統各匯流排之電壓降，各變壓器及電纜饋線之額定容量，與最大電力負載需
求。最後，在準備各種方案下經與台電多次協調，終於獲得台電核可松山線用電，使松山線
順利通車。

Discussion on the Power Transfer Mode for Service on Songshan Line

Wen-Lin Shih 1

Abstract

The Songhu ultra-high voltage substation was originally designed to supply the electricity
to the Songshan line before the operation of Songshan line, but in the end it failed to provide the
service as its construction was not completed on schedule. At that time, we faced the question of
whether the Taiwan Power Company (Taipower) would agree to supply the electricity for the bulk
substation of the Songshan line. In order to cope with the uncertainty of power supply for the bulk
substation of Songshan line, three power supply operation modes through AC load flow analysis
are taken into consideration 1. After the Taipower Songhu substation is built successfully and it will
carry out the power supply to the Songshan line using the original power supply planning mode;
2. Songhu substation has not been built to carry out the power supply to the bulk substation of the
Songshan line; 3. Songhu substation cannot be built, but the other substations of Taipower will take
its place in supplying the electricity to the bulk substation of the Songshan line. The change of the
power supply mode is required to ensure that the power supply system can be operated normally
under normal and abnormal conditions. By means of the AC load flow analysis, our power supply
system can meet all of the criteria including the voltage drop of the bus bar, the rated capacity
of each transformer and cable feeder, and the maximum power load demand. In preparation for
various proposals, we have obtained approval for the supply of electricity for the Songshan line
after a number of negotiations with Taipower so that the Songshan line can be put into operation as
scheduled.
