[Abstract]:Wireless monitoring of power transmission and transformation equipment can fully meet the requirements of comprehensive, real-time and accurate acquisition of information for transmission and transformation equipment. Combined with Internet of things technology, it can provide technical support for intelligent equipment and condition-based maintenance of power network equipment. Because the traditional monitoring system of transmission and transformer equipment has some problems in the aspects of information isolation, singleness, safety and so on, it is necessary to establish a unified model of equipment in constructing the monitoring system of transmission and transformer equipment based on Internet of things. Considering the requirement of real-time transmission of information in the monitoring system of transmission and transformation equipment, it is necessary to study the related performance of communication network, such as stability, security strategy, and so on, in order to improve the utilization rate of equipment and the security of power network operation. Based on the development of wireless monitoring technology for the Internet of things of power transmission and transformation equipment in China, the combination of transmission and transformation equipment and Internet of things technology is studied in this paper. Firstly, the key technologies related to the Internet of things are summarized and analyzed. Considering the characteristics of signal transmission of transmission and transformation equipment, Zig Bee technology is selected as the basis of Internet of things design. Secondly, the network model of power transmission and transformation equipment is modeled, and the network model is simulated by OPNET Modeler, thus the wireless monitoring function of transmission and transformation equipment based on Internet of things is realized. In addition, modern advanced technologies such as GSO (Group search Optimization algorithm) and WSN (Wireless Sensor Network) are used to optimize the network to obtain the optimal monitoring network, which provides technical support for the wireless monitoring technology of the Internet of things of power transmission and transformation equipment. Finally, taking the wireless temperature monitoring system of Weizhuang Station in Longyao County as an example, this paper validates the wireless monitoring technology of transmission and transformation based on Internet of things, and analyzes the benefit and feasibility of the application of this technology. The development direction and bright prospect of Internet of things wireless monitoring technology in power system are pointed out. It provides technical support and security guarantee for smart grid and state-of-the-art maintenance of power network equipment.
