影響中部科學園區電壓驟降事故範圍研究
The Range of Faults that Leads Voltage Sag in the Central Taiwan Science Park
摘要
科學園區為台灣高品質的高科技產業重鎮，民國100年新竹、中部及南部三大科學園區營業額為1.9兆元，因高科技產業製程其生產線每個環節都要非常準確、高度自動化及管制嚴格的製程控制參數，使得製程設備對電壓驟降非常敏感。 台灣地區因電力系統高密度地相互連結一起，故任何事故皆足以擾動系統，雖然單一電壓驟降事件所造成的損害並不會比停電事故嚴重，但當電壓驟降發生的次數遠多於停電事故時，所造成的整體損失就被突顯出來；依據電力公司紀錄，科學園區歷年來共發生315次電壓驟降，也說明對於防範電壓驟降仍有改善空間。 本論文主要是由電力系統架構方面模擬分析鄰近變電所匯流排及輸電線路發生事故時，造成主要供電中部科學園區用電之中科超高壓變電所電壓驟降嚴重程度及其受影響範圍；並且各別模擬討論變電所內分隔匯流排運轉及將輸電線路改為經常備用線路運轉時，事故時所造成之電壓驟降程度，經分析比較後發現將輸電線路設為經常備用線路時，其所受臨近事故造成之電壓驟降幅度最輕微，受影響之事故範圍最小，也降低其受事故影響之機率，並標訂出各種供電架構下，事故造成電壓驟降至標稱電壓50%、70%及80%之事故範圍，供電力公司加強管理維護及用戶加裝電壓驟降補償設備參考。

Science Parks are high-tech industry base. The three major science parks have a turnover of 1.9 trillion in 2011. Due to the high-tech industrial process need to be very accurate, the process equipment is very easy to be effected by voltage sag. Because of the power system interconnection is high-density in Taiwan, any faults is easy to perturb the system. Although the damage caused by a single event of voltage sag less than interruption, the overall loss is highlighted when the voltage sag event far more than interruption. According to the records of Taiwan Power Company, voltage sag event occurred 315 times in science parks over the years and that should be improved. In this thesis, main sections to simulate and analyze the level of damage and affected range by voltage sag in Chun-Gke Extra Substation which mainly power supply to Central Taiwan Science Park, when faults occurred in substation bus and transmission line that near by Chun-Gke Extra Substation. Also discuss voltage sag by faults when simulate to section substation bus and change the transmission line to spare line. The analysis shows that when transmission line changes to spare line, the damage caused by voltage sag has the smallest range and level, also reduces the probability of affected by the faults. And under the varied power supply system topology, set down the demarcation of nominal voltage 50%, 70% and 80% which voltage sag caused by faults. These data could be used as reference to improve the management, maintenance and user installation of compensation device for Taiwan Power Company.
