摘要
级联纵差保护系统基于基因图谱识别原理,采用光纤传输方式,解决信号通道的抗干扰问题,实现了短电缆线路的故障隔离,保证各级保护配合不存在死区,能有效预防越级跳闸事故的发生。
Cascade longitudinal differential protection system based on genome recognition principle,the use of optical fiber transmission,the signal path to solve the interference problem to achieve a short cable line fault isolation,to ensure the protection of all levels with the dead zone does not exist,can effectively prevent tripping accidents leapfrog occurs.
