摘要
针对目前微机保护不正确动作的原因 ,提出了采用保护分散布置技术 ,提高抗干扰能力 ;应用计算机数字通信技术 ,增强微机保护装置及外联回路的故障诊断功能及减少接点和端子接触不良引起的保护不正确动作因素 ;建立电网保护管理远程网络 ,实现“状态维修”。
For current misoperation causeof microcomputer relay protection,the paper introduces the technology of scattered arrangement protection to improve anti inteferance ability,the usage of computer digital communication technology to enhance fault diagnostic function ofmicro computer protection device and outside circuit and decrease bad contact ofcontactor and terminal which may cause ralay misoperation,establishment of electrical protection remote management network to realize maintenance under condition.
