变电站的电气设备误操作会严重威胁电力系统的安全稳定运行,可能导致大面积停电、电力设备损坏、系统振荡瓦解,甚至发生人身伤亡事故.为有效防止电气设备误操作引发的事故,我国在1990年即提出了电气设备“五防”的要求,并以法规形式行文规定了电气防误的管理、运行、设计和使用原则.
随着电力系统的发展,五防闭锁技术也不断更新,国内先后出现了机械闭锁、机械程序闭锁、电气闭锁、微机五防、一体化五防、在线式五防等技术,这些防误闭锁方式各有特点,应用场合也有所不同.
迈过21世纪的第一个10年,计算机技术、电子技术、通信技术、信号处理技术得到长足发展,变电站自动化经历了从无到有、从初级阶段到高级阶段的发展过程.本文将结合广东电网公司变电站的实际运行情况,介绍各种五防技术在变电站的应用,着重介绍微机五防和在线式五防在变电站的应用.

Electrical equipment of substation misoperation would seriously threaten the safe and stable operation of power system, could lead to massive power outages, power equipment damage, swing and disintegrated, or even personal injury accident occurs. To effectively prevent the misoperation of electric equipment caused by accident, in 1990 presented electric equipment in China, "five-prevention" requirements, and drafting provisions in statute form the electrical misoperation-principles of the management, operation, design and use.
With the development of electric power system, five anti-blocking technology is constantly updated, domestic has appeared a mechanical locking locking locking, computer, electrical, mechanical program of five measures, five-, online-five-proof integration technologies such as these anti-misoperation have different characteristics, applications varies.
The first 10 years of the 21st century, computer technology, electronics technology, communications technology, signal processing technology has been considerable progress, substation automation experience from scratch, from an early stage to advanced stages of the development process. This combined the substations of Guangdong power grid operation, covering the various five-prevention technique and its application in the substation, focuses on five measures of microcomputer and online-five protection in substation applications.
