Research on Automatic Planning Technology of Communication Path of Substation Relay Protection Network
In modern power system,relay protection network undertakes the important task of fast and reliable detection and location of power equipment faults.However,the traditional communication path planning method of relay protection network has some problems,such as long planning time,low efficiency and difficult to guarantee the path quality.In order to solve these problems,this paper proposes a relay protection network communication path planning technology based on automatic planning algorithm.Firstly,the related characteristics and problems of substation relay protection network are deeply analyzed.Secondly,the communication path planning model of relay protection is constructed,including objective function,constraint conditions and multi-objective normalization function;Thirdly,an automatic communication path planning method of substation relay protection network based on cuckoo search is proposed.Finally,the feasibility of the automatic planning algorithm proposed in this paper is verified by collecting and analyzing the data of substation relay protection network.The experimental results show that the algorithm has good performance in planning path,and can meet the needs of practical projects.
