Analysis for Influences of Series Capacitor Compensation on Transverse Differential Protection of Double-Circuit Lines on Same Tower

文章简单论述了横差保护应用于长距离输电线路的意义,简要说明了横差保护的原理,通过分析带串补电容的同塔双回线横差保护的动作行为,并提出串补电容对横差保护的影响,最后指出横差保护应用于带串补电容的同塔双回线路时需要注意的问题。

The article briefly discusses significances of transverse differential protection applying for long-distance transmission line and explains principle of transverse differential protection. It proposes that series capacitor has influence on transverse differential protection by means of analyzing transverse differential protection action of double,circuit lines on same tower with series capacitor. Finally, it points out attentions on transverse differential protection applying for double-circuit lines on same tower with series capacitor.
