开放、高效的通信技术是实现智能配电网的关键,文章研究智能配电网主站与终端的通信。由于IEC 61850协议已成为了智能配电网最重要的标准,以IEC 61850的MMS通信为基础,重点研究MMS通信机制及其在智能配电网的实现,详细介绍了智能配电网主站与终端通信模块的具体实现。最后搭建“主站-交换机-终端”通信测试平台进行通信测试,以远程遥控为例,使用Wire Shark抓取分析网络中的MMS报文,证明该通信方式的有效性。
Open and efficient communication technology is the key to realize the smart distribution network. The article studies the communication between the master station and the terminal in the smart distribution network. Since IEC 61850 protocol has become the most important standard for smart distribution network, based on IEC 61850 MMS communication, it focuses on MMS communication mechanism and its realization in smart distribution network. It introduces in detail the relationship between intelligent distribution network master stations and The concrete realization of terminal communication module. Finally, set up “master-switch-terminal” communication test platform for communication test. Take remote control as an example, use Wire Shark to capture and analyze MMS messages in the network to prove the effectiveness of the communication method.
