基于互联网通信的多功能箱式变电站终端

Multi-Function Box Type Substation Terminal Based on Internet Communication

文章设计了一个基于互联网的多功能箱式变电站终端,以STM32微处理器为核心器件,通过三相电能计量芯片配合采样电路实现对箱式变电站各电气参数的精确测量;可以实时采集变压器各绕组温度、湿度,实现了湿度监测调控,高温报警等功能。此外,该变电站终端通过以太网与电网控制中心(上位机)进行信息交互,将箱式变电站运行的各项参数实时显示在上位机的界面上,方便工程人员进行远程监控,真正实现了电网的智能化需求。

An internet-based multi-functional box-type substation terminal is designed.Using STM32 microprocessor as the core device,the terminal can accurately measure the electrical parameters of the box-type substation is realized by using the three-phase power metering chip and the sampling circuit and collect the temperature and humidity of each winding of transformer to realize humidity monitoring and control,high temperature alarm and other functions.The substation terminal exchange information with the power grid control center(upper computer)by Ethernet and show the parameters of the box substation in real time on the interface of the upper computer.It is convenient for engineers to carry out remote monitoring and realize the intelligent demand of power grid.
