基于ZigBee技术和GPRS的高压电网设备远程在线监测系统

Remote on-line monitoring system of HV power grid equipment based on ZigBee and GPRS

为避免高压电网设备因发热、泄露电流造成的停电事故,笔者提出搭建一个基于ZigBee技术和GPRS的高压电网设备远程在线监测系统,即采用低功耗单片机MSP430实现多点温度和泄露电流的采集和处理,通过ZigBee模块实现高压开关柜的温度和泄露电流信号的采集和传输,由无线数据传输模块MC39I通过GPRS网络将监测的数据传输到远程监控中心;通过对监控中心软件和数据采集终端和现场控制端软件的合理设计,实现监测点温度及泄露电流的在线监测、显示、数据查询、打印和报警等功能。

To avoid HV power grid equipment outage caused by heat and leakage current,the author proposed to establish the remote on- line monitoring system of HV power grid equipment based on ZigBee and GPRS. It is a system by which acquisition and processing of multi- channel temperature and leakage current could be realized by MSP430 microcontroller with low power consumption,besides acquisition and transmission of HV switchgear temperature and leakage current signal could be realized by ZigBee. The data acquired by the monitoring system is transmitted to the remote monitoring and control center through GPRS network by wireless data transmission model MC39 I. Due to the reasonable design of monitoring and control center software,data acquisition terminal and onsite control terminal software,the functions,including online monitoring,displaying,data searching,printing and warning of monitoring point temperature and leakage current,could be realized.
