Development of Internet of Things Technology and Application in Power System
The definition of the Internet of Things and the main technical features of the perception, network and application layers were presented in this paper. According to monitor and operation requirement of power system, application system for the service of power system was built based on Internet of things technology. The actual needs and application prospects of power internet of things were studied. Introduction Internet of Things technology (IoT) is advanced information acquisition and processing technology which has been widely used in industrial, agricultural, commercial, defense and other fields, and is the important means to promote future economic development. Fruitful theoretical research and technical verification results have been achieved in IoT. But at the same time, it is exile in overall solutions and integrated innovation for industry applications in China, and is exile in promotion and application in any industry and production field. Therefore, it is impossible to form the complete industrial chain from technology research and development, device development, system application to network services. The power IoT is the application of IoT in the smart grid, which is the result of the development of information and communication technology. The power IoT effectively integrates communication infrastructure resources and power system infrastructure resources, improves the efficiency of existing infrastructure utilization of power systems, provides important technical support for the power generation, transmission, transformation, distribution, and power consumption of the power grid. Therefore, power and material technology is the development trend of the future power system, and it is also the most urgent and important task of the national grid at the current stage. The basic concepts, characteristics and architecture of the power IoT is present in this paper, the key technologies of the power IoT. Finally, it focuses on the actual needs and application prospects of the power IoT.
