蓄电池性能和质量的好坏对发电厂和变电站是否安全运行有着重大的影响,其性能好坏的监测已经成为电力系统稳定、安全、可靠运行的关键因素之一。本文为了更好地对蓄电池的运行性能进行监测,开发了一套基于通用分组无线业务(GPRS)的电力系统蓄电池在线监测系统。该系统可以通过远程监控终端监测蓄电池的电压、电流和温度等运行参数。蓄电池维护人员如果需要知道蓄电池的运行状况,可以向蓄电池现场监测单元发送短消息,系统由GPRS模块借助通信网络和Internet网络将参数发至手机或监控中心,从而实现对电力系统蓄电池的在线实时监测。本系统还可以设置蓄电池电压、电流和温度的报警范围,如果蓄电池出现异常,则系统自动将报警信息发送至系统监控中心或维护人员手机,从而可以使蓄电池的故障很快地得到解决。实际应用表明了本系统的优越性。
The performance and quality of batteries have a significant impact on the safe operation of power plants and substations. The monitoring of their performance has become one of the key factors in the stable, safe and reliable operation of power systems. In order to monitor the performance of the battery better, this paper developed a power system battery on-line monitoring system based on General Packet Radio Service (GPRS). The system can monitor the terminal through the remote monitoring of battery voltage, current and temperature and other operating parameters. If the battery maintenance personnel need to know the running status of the battery, they can send short messages to the battery on-site monitoring unit. The system sends the parameters to the mobile phone or monitoring center through the communication network and the Internet network by the GPRS module, so as to realize online real-time monitoring of the power system battery . The system can also set the battery voltage, current and temperature alarm range, if the battery anomalies, the system automatically sends an alarm message to the system monitoring center or maintenance staff mobile phone, which can make the battery fault quickly be resolved. The practical application shows the superiority of this system.
