剩余电流波动预警短信控制方法的探讨

A Research on Control Law of Alarm Short Message for Residual Current Fluctuation

基于智能总保的剩余电流保护器监测系统已广泛应用于农村公变配电设备的远程监控并已见成效,但存在预警短信频发难以研判真正故障等问题.基于此提出一种曲线控制预警短信的方法,实现剩余电流波动预警信息筛选与故障研判.应用效果表明,该方法具有较强的实用性和推广性.

The residual current protection device monitoring system based on intelligent total security has been widely applied in remote monitoring and controlling for rural public power transformation and distribution equipment,and the approach has started to show effects,but there are still some problems such as frequent alarm short message and fault diagnosis.This paper proposes a curve control law of alarm short message,consequently filtering alarm information for residual current fluctuation and fault diagnosis have been implemented under this method.And the application of this method shows it is practical and worth promoting.
