基于MODBUS协议和IEC 61850协议的变电站通信电源监控研究

Research on Substation Communication Power Supply Monitoring Based on MODBUS Protocol and IEC 61850 Protocol

现有的变电站电源大多互相独立,导致系统间的通信协议互不兼容,难以实现信息共享。为解决这些问题,实现对变电站电源的智能化监控,提出一种基于MODBUS协议和IEC 61850协议的变电站通信电源监控方法。该系统利用IEC 61850协议标准化变电站通信电源系统数据,并通过软件转换模块实现不同通信协议之间的转换,实时监控变电站的不同电源。测试结果显示,该变电站电源监控系统能实现充电机与电池管理系统、逆变器、IEC 61850通信,有效解决现有电源监控系统数据共享难、监控信息不完整的问题。

Because the existing substation power supplies are generally independent of each other,the communication protocols between systems are incompatible with each other,and it is difficult to share information.In order to solve the above problems and realize intelligent monitoring of substation power supply,a monitoring method of substation communication power supply based on MODBUS protocol and IEC 61850 protocol is proposed.The system uses IEC 61850 protocol to standardize the data of substation communication power supply system,and realizes the conversion between different communication protocols through software conversion module to monitor different power supplies of substation in real time.The test results show that the substation power monitoring system can realize the communication between charger and battery management system,inverter and IEC 61850,and effectively solve the problems of difficult data sharing and incomplete monitoring information in the existing power monitoring system.
