浅析变电站五防系统可靠性设计

Reliability Design of the Five Protection system of A Substation

随着电力系统综合自动化技术的发展,微机五防在变电站防误系统应用越来越广泛。传统的电气五防的地位受到了挑战,那么要实现更加安全可靠的防误闭锁系统,该如何处理电气五防和微机五防的关系呢?针对这个问题,对两种闭锁技术的特点进行了详细的讨论,并结合变电站运行特点,提出了一种比较有效可靠的五防闭锁系统配置方案。

With the development of complex automation technology of the electric power system, the five protection of the microcomputer is more widely used in the preventive malfunction system, traditional electric five protection has heen challenged. Then to achieve safe and reliable incorrect block system, how to deal with the relationship between electric five protection and microtomputer five protection？ For this problem,the charactertstics of two block technologies are dis- cussed in detail. Combining with the operation eharacteristec of the substation, put forword a reliable configuration plan of five prevent block system.
