摘要
根据多端线路电流差动保护的要求 ,提出了一种基于GPS新型数字式分相电流差动保护硬件方案 ,同时还提出了较为完善的抗干扰措施。通过引入GPS定时技术解决了远距离多端同步采样问题 ,从而使电流纵差保护具有更高的可靠性。
According to the requirements of differential current protection for multi branch lines,a kind of new type digital phase disengage ment current protection hardware scheme is put forward,meanwhile,the more perfect anti interference measure is put forward too.Through the introduction of GPS timing technique,the synchronous data acquisition problem is solved,thus the longitudinal differential current protection possesses higher reliability.
