Abstract: The accurate positioning of the discharge resource is the key to ensure the stable operation of the transformer and to prolong the service life. The proposed simulated annealing hybrid particle swarm algorithm was tested by two-standard test functions. It was found that the stability and precision of the result were higher than that of the general particle swarm optimization (PSO). The positioning model of particle discharge (PD) with this algorithm could accurately locate the PD points in the transformer. Compared with the adaptive and conventional particle swarm optimization algorithm, the accuracy of the results was improved, which provides references for site location tests.
Key words: transformer; partial discharge; hybrid particle swarm; ultrahigh frequency; location
