Construction of automatic monitoring terminal platform for abnormal voltage state of electric power metering device

针对常规电力计量装置电压异常监测终端平台抗干扰能力较差的问题,构建电力计量装置电压异常状态自动监测终端平台。介绍了平台的硬件结构和组成,设计了DSP模块,对自动监测终端平台的电力计量装置接入方式——直接接入方式和间接接入方式进行了分析;利用C语言编写软件,实现了电力计量装置电压异常状态自动监测终端平台自动抄表、监控、故障记录、参数设定与查询、异常检测等功能。对该平台与传统平台进行了试验对比,结果表明,该平台抗干扰能力强,能准确地监测到电网电压的异常情况。

According to the poor anti-interference ability of the terminal platform for voltage anomaly monitoring of conventional power metering device,it constructs an automatic monitoring terminal platform for abnormal voltage state of power metering device.It introduces the hardware structure and composition of the platform,designs the DSP module and analyzes the access modes of the power metering device of the automatic monitoring terminal platform——direct access mode and indirect access mode.The software written in C language realizes the functions of automatic meter reading,monitoring,fault recording,parameter setting and query,abnormal detection and other functions for the automatic detection of the voltage abnormal state of the power metering device.It compares this platform and the traditional platform by the experiment,the results show that the platform has strong anti-interference ability and can accurately monitor the abnormal situation of grid voltage.
