摘要
以实例给出了企业供配电系统中微机保护装置、智能断路器与Modbus通信的硬件接线。阐述了供配电系统中Modbus通信协议的模式和功能代码的应用,并设计实现了该供电系统的组态监控界面。运行结果表明,以Modbus现场总线建立的企业智能供配电系统具有良好的开放性、灵活性,能够实现企业供配电系统的智能监测与自动控制。
Microcomputer protection device, intelligent circuit breaker and Modbus communication hardware connection in enterprise power supply and distribution system were presented as examples. Model of the Modbus communication protocol and the application of function code in power supply and distribution system were elaborated. Configuration monitoring interface of the power supply system was designed and implemented. The running results show that enterprise intelligent power supply system based on Modbus has a good openness, flexibility, can realize intelligent monitoring and automatic control.
