电力监控系统防越级跳闸方案的研究

Research of Scheme of Preventing Override Trip by Use of Power Monitoring System

针对单一防越级跳闸方案和地面供电系统防越级跳闸方案均不能有效解决煤矿井下越级跳闸故障的问题,提出了一种采用电力监控系统解决煤矿井下越级跳闸故障的方案;以河南平宝煤业有限公司供电网络为例,详细介绍了该方案的实现原理及具体实施情况。实际应用表明,该方案实现了上下级开关的配合,有效防止了越级跳闸故障。

In view of problem that scheme of single preventing override trip and scheme of preventing override trip of surface power system cannot solve underground override trip fault effectively,the paper proposed a scheme that using power monitoring system to solve underground override trip fault.Taking power network of Henan Pingbao Coal Industry Company as example,it introduced realizing principle and implementing situation in details.The actual application showed that the scheme can realize cooperation of upper and lower switches and prevent override trip fault effectively.
