THE OPTIMAL DESIGN OF A 3-PHASE 5-LIMB TRANSFORMER CORE BASED ON THE SIMULATED ANNEALING ALGORITHM METHOD

Be based on the analysis of the distribution of the electromagnetic field of a transformer core, the simulated annealing algorithm method is used in the optimal designs of the side yoke of a 5 limb core. With the numerical calculation results of the distributions of the loss and the electromagnetic field, the optimal design objective function is established, and the optimal size of the side yoke of 5 limb core is obtained with the simulated annealing algorithm. The steps of the optimal design and an example are given detailedly.
