Research On The Communication Technology Of Internet Of Things In Power Systems

Power internet of things is the application of internet of things in the smart grid. It is the results of information and communication technology develop to a certain stage and it will effectively integrate communication and power systems infrastructure resources. In order to improve the information level of power system and improve the utilization efficiency of the existing power system infrastructure and provide important technical support for grid generation, transmission, transformation, distribution, electricity and other sectors, it needs to involve wireline, wireless, satellite different communication technologies..Paper’s main work is as follows:(1) Analysis the demand of power network of things for communication technologies. Firstly, this paper introduces the basic meaning of the power internet of things, and studies the key technology of this. Then, the power internet of things in the ICT requirements were studied. At the same time communication mechanism were analyzed.(2)Study the infrastructure of the power network of things. Networking was the demand for electricity for communications technology, set up the power of things overall communications infrastructure, and the power of the main things communication technology were analyzed. Meanwhile, the power of things in the problems of communication technology research, pointed out that the channel noise power is the main factor was the impact of networked communications.(3) It focuses on the power of things for power line carrier channel. Firstly, the power IOT PLC transmission characteristics and the channel environment. Then, the main power line carrier channel noise is analyzed, and a mathematical model of a different noise.(4) Using Simulink tools Power Line Communications presence of various noise simulation and analysis. According to the mathematical model of the power line channel noise, the use Simulink to simulate the generation mechanism of various noises, communication and how to weaken the influence of noise on the power of things are analyzed.
