A Simulation and Control Method for Ring Network Cabinet of Distribution Network Based on Wireless Network Communication

针对环网柜改造中加装DTU调试的困难,提出一种基于无线网络通讯的环网柜离线仿真模拟与控制方法。以单片机控制为主体,采用继电器及其触点模拟环网柜的开关实现电气"五防",利用无线网络通讯建立上位机与单片机的多信道通讯,不仅可以就地查看、操作、显示,还可以通过单片机控制的串口无线通信实现远程遥控、遥信,同时模拟环网柜电气量的测量,并且上位机可以对操作记录进行显示、存储、打印输出。最后,对单片机接口进行了标准化定义,并预留了扩展接口以备后期完善"三遥"功能。该模拟器的仿真与控制方法为为环网柜的DTU上线实施提供重要的参考依据。

Aiming at the application problem of the DTU during the ring net cabinet reforming,a simulation and control method for Ring Network Cabinet of Distribution Network based on Wireless Network Communication is put forward in this paper.The simulation and control system is dominated by single chip microcomputer.The switches and the five-defense of the ring net cabinet are presented with the relay as well as its auxiliary contacts.With the wireless multichannel Communication between single chip microcomputer and host computer,not only the local measurement and records can be checked,but also the remote control and telesignalling are accomplished.Meanwhile,the operation records,information storage and printing can be showed and controlled on host computer.The single chip microcomputer interfaces are defined and some reserved ports are used for future expand in order to accomplish the telemetering.The simulation and control method presented in this paper could be used as the reference for the application of ATU on ring net cabinet in power system.
