配变监控系统的防窃电功能实现

介绍一种应用在低压配电网中具有反窃电功能的基于移动GPRS的配变监控系统。在硬件上是通过ADE 7758反窃电数据采集模块实现防窃电。配变远方终端软件采用C语言编程,主站采用VC 6.0进行编程。通过功率比较法和电量比较法,实现对实时数据的处理和防窃电。利用配变监控系统的实时特性,在配变监控系统中开发防窃电功能,相比采用防窃电电能表防窃电,具有快速侦察窃电、实时告警提示等优点。该系统已经在实际中使用,实践表明其投资少,效果良好。

Realization of electricity stealing prevention in distribution transformer monitoring system

A distribution transformer monitoring system based on GPRS with the function of electricity stealing prevention is introduced.The electricity stealing prevention is mainly realized in hardware by ADE 7758 data acquisition module.The software of distribution transformer terminal unit is written with C language and the software of main station is developed with Visual C 6.0.Both power comparison and electricity comparison are applied to process the real-time data and prevent electricity stealing.Compared with the electricity stealing preventive power meter,using the real-time characteristics of distribution transformer monitoring system to develop the function of electricity stealing prevention is better in detection speed and real-time alarming.The site practice shows its effectiveness and economy.
