Research On Quality Evaluation Algorithm Of Heterogeneous Communication Network In Distribution Network

The power system is highly dependent on the communication network,so that the reliability research of the distribution network is put in a very important position.Therefore,it is necessary to study the reliability of distribution network.In this paper,it analyzes the heterogeneous distribution communication network and its framework,and at the same time,expounds the heterogeneous distribution communication environment and business classification,and studies the reliability index.On this basis,the network construction of the economy,reliability,site voltage rating and business distribution and other factors are taken into account,and the method of optical cable line planning for distribution communication optical transmission network is presented.Firstly,the model of the optical transmission network is abstracted based on the structure of the graph,and the weights of the nodes in the graph are used to distinguish the voltage levels of different sites to simulate the real network environment.And then,the network cost function is introduced,and the network reliability function is established based on the site formation rate.In the process of optimization,the genetic algorithm theory of bionics is introduced,and the genetic algorithm is optimized by artificial immune and pigeon group optimization algorithm,which makes it more suitable.Finally,the proposed method is applied to practical problems,and the effectiveness of the proposed method is verified.
