Improved Ant Colony Algorithm and Its Application in Parameter Identification for Dielectric Response Equivalent Circuit of Transformer
摘要
Abstract
Return voltage measurement is an effective non-destructive testing method for diagnosis of transformer in- sulation state. Establishing transformer dielectric response equivalent circuit model is an effective way to analyze the relationship between insulation aging and characteristic quantity. Therefore, on the basis of establishing equivalent circuit mathematical model, equivalent circuit parameters identification was transformed into the mathematical opti- mization, then the improved ant colony algorithm was adopted to identify model parameters. Four test functions proved that using both global optimal solution and each iteration optimal solution in global pheromone updating could improve convergence speed, expand search scopet and using the dynamic local pheromone updating could also strengthen the ability of jumping out of local optima! value. The contrast of polarization spectra between model cal- culation and practical measurement shows that the solved equivalent model can accurately reflect the medium re- sponse characteristics of oil-paper transformer insulation.关键词
