The safety of transmission line plays a important role in power system safety it is not only the requirement of ensure supply power reliability, but also the necessary precondition of enhance power system stabilization, to remove faulty line quickly and accurately, also keep non - faulty line continuous work when some transmission line faults current differential protection is a kind of simple, reliable and good - selective protection manner to any variety of transmission lines, power system development needs current differential protection apply to transmission lines, moreover the advancement of electric and communication technology enable current differential protection apply to transmission lines firstly, the paper discusses, analyses the research and application transmission line protection in detail, compare the principle and realistic presupposition of general line pilot protections secondly, because conventional current vector differential protection are influenced easily by load current and transitional resistance, in order to at the same time quicken protection act, the principle and criterion include work characteristic of differential protect based on fault component sampled values are studied, results shows that differential protect based on fault component sampled values excels general vector current differential protection in reliability, sensitivity and anti - saturation of current transformer in addition, synchronous current sampling methods at all terminals of line is analyzed and estimated lastly, the principle and criterion. also device design about current sampling values differential protection based on optical fiber communication, which apply to short transmission lines are concretely investigated,
基於基爾霍夫定律的電流差動保護無論對於何種形式的輸電線路都是一種簡單、可靠、選擇性強的保護形式，電力系統的發展使得電流差動保護應用於線路保護成為需要，而電子、通信技術的發展使得電流差動保護應用於輸電線路成為可能。首先，本文對目前線路保護的研究和實際應用情況進行了討論和分析，比較了常用線路縱聯保護的實現原理和實現條件及優缺點。其次，針對常規相量電流差動保護易受正常負荷電流和故障過渡電阻影響的缺點，同時為加快差動保護的動作速度，對基於故障分量瞬時采樣值電流差動保護的原理、判據、動作特性等作了討論和分析，結果表明基於故障分量瞬時采樣值電流差動保護在可靠性、靈敏度、抗電流互感器飽和方面明顯優于常規相量電流差動保護，對電流差動保護各端的同步采樣方法和數據通信也進行了分析和評價。Midway through the half came the game ' s first booking ? boulharouz cautioned for a foul on agbonlahor after the speedy villa youngster exposed his opponent with a sharp turn
