微机五防系统在运行中的异常现象及改进措施

Abnormal Phenomenon and Improvement Measures of Microcomputer Five Preventing System

防误闭锁是保证变电站安全运行的重要方式之一。针对浦口供电公司微机五防系统投运初期,运行人员操作过程中经常出现走空程序和手动置位的现象,为最大限度降低因防误装置缺陷引起的恶性误操作事故,结合现场工作经验,分析了异常原因并予以改进,有效降低了现场操作中微机五防系统人工干预的几率,提高了操作可靠性。

Anti-operation lockout is one of the important ways of ensuring safe operation in substations.In the initial operating stage of microcomputer five-preventing system in Pukou Power Supply Company,the phenomenon of empty procedures and manual setting actions in process of operation often appears.In order to reduce harmful accidents caused by anti-operation device,cause of abnormity is analyzed and improvement measures are proposed which are based on practical experience.And then the probabilities of manual intervention for microcomputer five-preventing system can be reduced,and the reliability of operation can be improved.
