Data Communication Performance Analysis Of Smart Distribution Power Grid Based On Wireless Sensor Networks

Wireless sensor networks has a broad application prospects in the smartdistribution grids with its unique low-power, rapid self-organization andsuperior interoperability, The difficulty of Using wireless sensor networks insmart grid communication is to meet the electric power industry with the griddata communication specification of real-time communication and reliabilityrequirements in limited network resources. This paper researched overallcomposition of architecture, QoS-MAC algorithm and routing mechanism of thesmart grid wireless sensor network data communication system in order toimprove the real-time and reliability requirements of intelligent distributionnetwork data communication system.This paper has the following main content:1.The terminal equipment and wireless sensor network node structure ofsmart grid was analyzed; the whole and the local topology model of smart gridwireless sensor networks were proposed based on wireless sensor networkarchitecture features.2.A QoS-MAC protocol algorithm of wireless sensor networks in smart gridwas proposed; an unfair competition mechanism of real-time and non-real-timedata transmission channel was proposed; a mathematical model of node bufferqueue status, channel access mechanism mathematical models and performanceanalysis based on Markov chain was established and simulated. Experimentsshowed that the method can improve the data transfer performance of wirelesssensor network in smart distribution grid.3.A data transmission path selection model of wireless sensor network insmart distribution grid was established, wireless sensor networks, real-time andreliability as the goal, the model gives a specific assignment, and use ofbreadth-first search to solve the above optimal path. The article examplevalidates the feasibility of the method, and verify that the routing pathreconstruction transport mechanism in single node failure conditions. This paper selected the distribution network data communication systemimplemented in Huangshan Power Supply Company as simulation example, andthen calculated the network QoS-MAC protocol and routing algorithm of theexample to propose the actual data. Results show that this method is suitable forthe structural characteristics of smart grid wireless sensor and to meet therequirements of real-time reliability.
