Research on Low Power Sensor Networking Technology of Transformer Equipment Based on Node Energy

Abstract

With the development of smart grid and Internet of Things technology, the level of substation intellectualization is getting higher and higher. In order to monitor the substation equipment in real time and obtain the information of equipment operation status, a large number of monitoring sensors are installed on the equipment. Because of the complex internal environment and many dangerous factors in the substation, monitoring nodes usually use wireless communication and rely on their own batteries for power supply. Because the replacement of batteries is not convenient, node power consumption is very important for its lifetime. Traditional monitoring devices install SIM card, but according to this way, the power consumption of the device is large, so it needs to be connected separately to supply power for the device. At present, the main method is to form a network in the station, and the nodes gather information uniformly in the station. Because of the different transmission distance, each node sends information directly, which leads to its own battery consumption too fast, and the generation time of nodes is relatively short. In order to prolong working time and improve energy efficiency, a low-power sensor network technology based on node energy for transformer equipment is proposed in this paper. The energy consumption of each node is balanced by considering the node energy in the process of information transmission, thus prolonging the node lifetime and monitoring the network lifetime.
