The key technology of distributed perception of power transmission line based on intelligent algorithm
To solve the problem of distributed fault sensing accuracy of power transmission lines,a fault location algorithm based on travelling wave time difference and BAS-CPSO is proposed.Firstly,the Tianniu algorithm is introduced to improve the chaotic particle swarm optimization algorithm,so as to improve the optimization performance of chaotic particle swarm optimization algorithm.Then BAS-CPSO algorithm is used to locate the fault accurately according to the traveling wave time difference of transmission line fault.The test results show that compared with the mainstream search algorithms such as SPSO,CPSO and BASPSO,the chaotic par-ticle swarm optimization algorithm introduced by the Tianusu algorithm has better search performance,higher convergence accuracy and search speed in the test function,and better optimization effect.In the simulation experiment of power grid transmission system,the absolute error of fault location for all lines of the proposed algorithm based on traveling wave time difference relationship and BAS-CPSO is less than 100m,which is far less than 300m of actual transmission line fault location accuracy.Under the same simulation condition,the positioning error of the proposed positioning algorithm is reduced by 81.66％and 45.92％compared with the two-end positioning method and the traditional network positioning method,and the positioning accuracy is high,which is worthy of further re-search and popularization.
