基于改进GA算法的电力变压器优化设计

Modified GA Algorithm-based Optimal Design of Power Transformers

针对中小型电力变压器优化设计问题,同时响应国家节能减排的号召,对GA算法进行改进并分别应用到电力变压器优化设计中的有效材料成本单目标和总损耗的单目标中。将改进GA算法优化所得数据和使用原GA算法以及人工设计进行对比分析,结果表明改进GA算法优化效果较好,运行时间较快,能有效减少电力变压器所需的材料成本或损耗。

Aiming at the optimization design of small and medium-sized power transformers,and responding to the initiative of national energy saving and emission reduction,a modification was made on GA algorithm,and the modified algorithm was applied separately to the single objective of effective material cost and the single objective of total loss in the optimal design of power transformer.Comparative analysis with original GA algorithm and manual design showed that the modified GA algorithm proposed by this work has better optimization effect,faster running time and can effectively reduce cost or loss of materials required for manufacturing transformers.
