电网配变监测计量终端在低压线路监测中的应用与探讨

Application and Discussion of the Measurement Terminal in the Monitoring of Low Voltage Line in Power Grid

摘要: 南方电网台区低压线路没有成熟有效的线路电能质量在线监测方法，目前所使用的技术无法监测台区低压侧线路的情况，安装的电压监测仪只能测安装点的电压，无相序标识。该课题研究的是一种基于台区低压配电载波通信在线监测新系统，通过台区配变监测计量终端所配的GPRS通信方式，由配电载波通信前端机接收到配电载波通信后端监测机的数据信息，再由配变监测计量终端传送到主站，实现低压线路远程在线监测。充分发挥了配变监测计量终端通信通道，实现了资源共享，方便推广普及。

Abstract: A southern power grid court of low pressure line has no mature and effective online monitoring method of line power quality. The technology in use today can’t monitor the situation of low voltage side lines; the installed voltage monitoring instrument can only measure the voltage of installation point, noncoherent identification. The subject study is a kind of new system based on the courts’ low voltage distribution carrier wave communication online monitoring, through the GPRS communication mode of the courts’ monitoring and measuring terminal, by the power carrier communication front-end machine receive the data information of distribution carrier communication back-end monitoring machine, then by monitoring and measuring terminal changeable again transfer it to the host, to realize low voltage line remote online monitoring, give full play to the with monitoring and measuring terminal changeable communication channel, realize the resource sharing, and is convenient to generalization and popularization.
