  1. Unified power flow controller ( upfc ) is one of the most powerful and most promising controllers of facts. if we use upfc to control the transmission parameters, terminal voltage, line impedance and phase angle in normal situation and use it to compensate zero sequence and negative sequence currents when one of transmission lines is cut off, we can implement two phases operating in high voltage transmission lines, which can improve stability and reliability for the transmission system

    統一潮流控制器( upfc )是功能最強、最具發展潛力的靈活交流輸系統( facts )控制器之一,如果在常規條件下,用upfc實現輸線路的壓調節、移、潮流控制、尼振蕩等功能,在發生單永久性接地或單斷路故障時,由傳統的三跳閘改為單跳閘,用upfc的並補來濾除兩端系統的和負流,用upfc的串補來提高輸線的傳輸功率,以實現兩長期運行,那麼輸系統的穩定性、可靠性將大大提高。
  2. Firstly, we analyze the transient and steady character of single phase high - impedance grounding fault. secondly, based on wavelet analysis on checking mutational signal and direction high frequency protection theory, utilizing zero sequence current and module current, this paper provides a new scheme including fault starting element, fault phase selection element, directional element and main criterion. this scheme can bear high impedance and is immune to system surge and frequency warp, which gets over the shortcoming of the lack of sensitivity

    由於現有的保護方案無法快速有效地切除此類故障,本文在詳細分析了單接地故障的穩態和暫態特性的基礎上,從小波分析原理出發,利用小波變換檢測突變信號的原理,以流、模流等為研究對象,結合方向高頻保護的原理,設計了一套包含啟動元件、選元件、方向元件、主保護的保護新方案。
