Abstract

In response to the shortcomings of traditional fiber optic and wireless public network communication methods in the context of distributed photovoltaic access, this study carries out the research and design of terminal equipment based on the 230 MHz power dedicated wireless frequency band. According to the technical specification for the power communication private network, the terminal software architecture and group cooperative control strategy are designed, and three modules—wireless communication, data acquisition, and control execution—are integrated to realize the real-time collection and remote centralized control of the status of distributed photovoltaic equipment. Through on-site pilot deployment and testing, the communication delay of the terminal meets the requirements, the signal coverage matches distributed photovoltaic scenarios, and the group regulation and control response is timely. The research results indicate that the wireless private network terminal can make up for the shortcomings of existing communication methods, meet the needs of distributed photovoltaic clustering and intelligent regulation, and has strong promotion value and engineering practical significance.
