Research on communication technology of power monitoring system based on medium voltage power line carrier and low power wide area network

The Power Line Carrier (PLC) communication makes full use of the power line which has already been laid as the transmission medium, and does not require earthwork construction and communication line laying, which can achieve rapid construction. While, the wireless communication technology provides a good solution to solve the problems of high cost, poor flexibility and difficult installation and maintenance of wired communication technology. In this paper, based on the combination of medium voltage power line broadband carrier communication technology and Low-Power Wide Area Network(LP-WAN), proposes a communication technology of remote power monitoring system combined with wired and wireless, which can achieve real-time communication of power system with low cost and long distance.
