基于无线通讯的变电站分布式核相结构实现及测试

Realization and test of distributed nuclear phase structure of substation based on wireless communication

为了提高变电站现场调试时核相工作不易实施的困难,提出了一种基于WIFI无线通讯的变电站分布式核相结构设计。通过无线通讯来为核相主机以及各个采样终端之间建立数据通信渠道,最终实现整站核相工作实现效率快速提升。相结构选择WPA2AES加密条件下的安全传输模式,并利用点对多点的MAC锁定模式构建局域网传输策略,确保实现无线数据传输的可靠性。进行室内测试的过程,将采样终端和核相主机置于不同的房间内,相互距离为40m,墙壁位于无线传输路径之间。开展室外测试时,采样终端跟核相主机的距离等于160m左右,没有障碍物影响无线传输路径。

In order to improve the difficulty of nuclear phase implementation in substation field debugging,a distributed nuclear phase structure design of substation based on WIFI wireless transmission network is proposed.Through wireless transmission network,data communication channels are established between the nuclear phase host and various sampling terminals,and finally the nuclear phase work of the whole station is rapidly improved.The phase structure selects the secure transmission mode under WPA2 AES encryption,and constructs the LAN transmission strategy by using the point-to-multipoint MAC locking mode to ensure the reliability of wireless data transmission.During the process of indoor testing,the sampling terminal and the nuclear phase host were placed in different rooms with a distance of 40 m from each other,and the walls were located between the wireless transmission paths.When conducting outdoor tests,the distance between the sampling terminal and the nuclear phase host is equal to about 160 m,and no obstacles affect the wireless transmission path.
