基于以太网电力网参数远程测试仪的实现

Test the realization of the instrument according to the ether net electric power net parameter long range

介绍了利用LabVIEW的VISA标准和内置的TCP节点,设计了由客户端通信程序和带有TCP/IP网络协议接口的电力网相电压、相电流及功率因素测控仪器组成的电力网参数远程测控系统。控制中心(远程客户)可以通过控制台上虚拟仪器面板的各种按键、旋钮以及滑动条等,实现对电力网相电压、相电流及功率因素等电参数的远程测控。

This paper introduces a design of remote measuremnt and control system of power net parameters by LabVIEW＇ VISA standard and built-in TCP nodes. This system is made up of the client-communication program and the measurement and control instrument of the power net＇s phase voltage, phase current and power factor, this power net is of TCP/IP net agreement interface. The control center （remote client） can measure and control remotely the power net＇s phase voltage, phase current and power factor by every buttons, knobs and slide of the virtual panel on the console.
