More and more wireless communication technologies are used in various power equipment monitoring systems. The power supply conditions and electromagnetic environment of various systems are not the same, the amount of communication data is different too, and there are many differences between the requirements of network. There is a lack of research on the design strategy of wireless network structure with certain generality. Firstly, the wireless communication technology and its network structure in the existing systems were analyzed. Secondly, the power consumption, communication distance, transmission security, transmission speed, construction and maintenance cost of communication technology are compared and analyzed. Then, the characteristics of all kinds of data in the monitoring system were summarized, and a design strategy of wireless communication network for an example system was given. This paper is a good guide for design strategy of wireless communication network in power equipment monitoring systems.
