Remote transmission method of intelligent power concentrator data collection based on Beidou satellite communication

Abstract As an external auxiliary device, the automation level of each simulation subsystem of the intelligent power concentrator varies greatly, and there are problems with communication capacity and packet loss in custom data collection. Therefore, this article proposes a remote transmission method for intelligent power concentrator data collection based on BeiDou satellite communication. By utilizing the BeiDou front-end gateway and BeiDou collection terminal to work together, both the frequency of instructions issued by the main station and the efficiency of data reception have been improved. In the design of remote data transmission, measures such as correcting collected data, removing redundant information, and reasonably unpacking and supplementing packages are taken to ensure the accuracy, efficiency, and stability of data transmission. At the same time, the system protocol should be customized according to the communication protocol, and the communication capacity and packet loss problems should be solved through packet sending and packet loss retransmission mechanisms. The experimental results show that compared with other methods, when the information size is 1200 bits, the transmission delay of our method is 2.5 seconds, and the packet loss rate is about 6.4%. It has excellent indicators such as data transmission integrity, stability, and resource utilization. This method has significant advantages in data collection efficiency and can effectively support the safe, stable, and efficient operation of power systems, providing strong support for the field of smart grid data processing.
