1. 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 ,
   基于基爾霍夫定律的電流差動(dòng)保護(hù)無(wú)論對(duì)于何種形式的輸電線路都是一種簡(jiǎn)單、可靠、選擇性強(qiáng)的保護(hù)形式，電力系統(tǒng)的發(fā)展使得電流差動(dòng)保護(hù)應(yīng)用于線路保護(hù)成為需要，而電子、通信技術(shù)的發(fā)展使得電流差動(dòng)保護(hù)應(yīng)用于輸電線路成為可能。首先，本文對(duì)目前線路保護(hù)的研究和實(shí)際應(yīng)用情況進(jìn)行了討論和分析，比較了常用線路縱聯(lián)保護(hù)的實(shí)現(xiàn)原理和實(shí)現(xiàn)條件及優(yōu)缺點(diǎn)。其次，針對(duì)常規(guī)相量電流差動(dòng)保護(hù)易受正常負(fù)荷電流和故障過(guò)渡電阻影響的缺點(diǎn)，同時(shí)為加快差動(dòng)保護(hù)的動(dòng)作速度，對(duì)基于故障分量瞬時(shí)采樣值電流差動(dòng)保護(hù)的原理、判據(jù)、動(dòng)作特性等作了討論和分析，結(jié)果表明基于故障分量瞬時(shí)采樣值電流差動(dòng)保護(hù)在可靠性、靈敏度、抗電流互感器飽和方面明顯優(yōu)于常規(guī)相量電流差動(dòng)保護(hù)，對(duì)電流差動(dòng)保護(hù)各端的同步采樣方法和數(shù)據(jù)通信也進(jìn)行了分析和評(píng)價(jià)。
