中文拼音 [fùxùdiànzǔ]
負序電阻
英文
negative sequence resistance-
The negative sequence current of impedance - matching balance transformer
阻抗匹配平衡變壓器的負序電流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電系統（ facts ）控制器之一，如果在常規條件下，用upfc實現輸電線路的電壓調節、移相、潮流控制、阻尼振蕩等功能，在發生單相永久性接地或單相斷路故障時，由傳統的三相跳閘改為單相跳閘，用upfc的並補來濾除兩端系統的零序和負序電流，用upfc的串補來提高輸電線的傳輸功率，以實現兩相長期運行，那麼輸電系統的穩定性、可靠性將大大提高。As a result, this paper gives a corresponding harmonic prevent me asure. finally, according to the asymmetrical characteristics of electrical traction loads, this paper studies the negative sequence currents under different loads and makes a piece of advice for reducing the negative sequence currents produced
最後，還根據電力牽引負荷三相不對稱的特點，分析了阻抗匹配平衡變壓器在不同負荷條件下的負序電流，對如何減小電力牽引負荷的負序電流提出了一點建議。Since it is immune to load change, immune to the value of grounded resistance change and its parameters can be easily measured, the fault location algorithm can be widely applied to the power distribution networks
基於此論文還編制了單相接地故障定位的計算機通用程序。該測距演算法不受負載參數變化的影響，不受接地過渡電阻值大小的影響。The top surface of the bearing bar are formed by a series of notches thus enhancing its nonslip characteritics. it is particularly suitable for use in slippery conditions such as oil refineries, tankers, stair ways etc
是由負載扁鋼和橫桿按一定間距經緯排列，在高壓電阻焊機上焊接而成原板，經切割切口開孔包邊等工序深加工而成客戶要求的成品。分享友人
