在電力系統的發電、輸電及供電過程中,電能計量是非常重要的一環,而一般高壓用電戶之計費電表組(Meter of Facility, MOF)內除了裝置有效電表及無效電表外,必須裝置高壓比流器(Current Transformer, CT)及高壓比壓器(Potential Transformer, PT),計量裝置的故障無論是內部元件故障或人為造成接線故障,都將導致不能準確的計算用電戶之電量,因此研究檢測故障的方法非常具有實用性。本研究依各種配線架構方式,模擬多種電表誤接之故障模型,並分析其電力特徵,再以圖控介面程式(Borland C++ Builder, BCB)設計一套診斷錯誤接線之檢驗系統,減少人為判斷錯誤之機率,研究結果顯示此系統可即時準確的判斷異常情況及監測,以供台電公司與用電戶參考之依據。
In the process of power generation, transmission and distribution, the energy measurement is a very important part in power system. The high voltage consumers have watt-hour meter, var-hour meter, high voltage current transformer(CT) and high voltage Potential Transformer(PT) in the Meter of Facility(MOF). The failure of Metering devices contains internal components that operate in wrong way and wiring connect of human’s mistake, That will not accurately calculate the energy of customers. Therefore, the research is practical on the method of fault detection. In this study, according to the wiring structure of Taipower. Simulate plenty of fault models of meter incorrect wiring connection, And analyze the relation of electrical parameters. Finally, utilizing Borland C++ Builder designs a fast and accurate way to detect incorrect wiring connection, and reduce the probability of mistake by human’s determining. The result of this study shows that system can determine incorrect wiring connections accurately and monitor immediately. Consequently, this paper provides reference for Taipower and customers.
