Power Distribution Automation Communication Network Design And Optimization Of District Level

With the deepening of the construction of ubiquitous power Internet of things,the explosive growth of distribution automation,power metering and other distribution network terminal equipment,massive business access puts forward higher requirements for the real-time and security of distribution communication access network.Wireless private network has the characteristics of high reliability,high bandwidth and easy expansion.It can transmit power control services.It is an important means to meet the explosive growth of services,solve the "last kilometer" terminal service access problem of distribution network,and improve the safe and stable operation of distribution communication network.This paper takes the construction of electric power wireless special network in Xuzhou as the research object.Firstly,it introduces the relationship and development of power grid and electric power communication network,analyzes the characteristics and shortcomings of the construction of distribution network and distribution communication network in Xuzhou,compares the advantages and disadvantages of various access network communication technologies,and determines the direction of building wireless special network as the operation level of distribution communication network.Under the guidance of coverage,capacity,security,quality and cost,this paper designs the system architecture of wireless private network,and analyzes the influence of base station coverage and base station capacity on network design.Finally,this paper innovatively uses Monte Carlo method to solve the base station coverage and calculate the fitness function,and constructs the genetic algorithm and particle swarm optimization model of base station coverage optimization respectively,and uses MATLAB simulation calculation.The results show that the coverage,redundancy and adaptability of genetic algorithm are better than that of particle swarm optimization.The optimized scheme is applied to the project construction,and the practice shows that the power business in the construction area of the scheme has achieved full coverage,and the business operation index has been significantly improved,ensuring the security and reliability of the distribution communication network.There are 41 figures,23 tables and 55 references in this paper.
