| 摘 要： | 目前,滁州供电公司220 kV线路主保护通道主要为高频通道和光纤通道。由于高频保护原理是闭锁式保护,每天都要进行交换试验;因此在现场实际运行中,高频通道维护量较大。随着集控站不断建设,各变电站改为相继无人值守,现场的高频通道试验方法已不能满足无人值守的要求;为此,研究建立了远程通道交换试验系统,对传统高频通道交换试验系统进行改造,取得了良好效果。

| Abstract: | At present,220kV line protection channel are mainly for high-frequency channel and fibre channel in Chuzhou power company.The exchange tests are proceeded everyday caused by high-frequency protection principle is blocking protection. Therefore,the maintenance of high-frequency channel is very large in actual operation on the spot.With the continued construction of centralized control station,the substation to have unattended.On-site test methods for high-frequency channels can not meet the requirements unat... |
