论文摘要
变压器的设计参数的优化是提高效率并降低材料成本的关键任务。这项研究提出了一种建模三相变压器并优化设计参数以最大程度减少体积和损失的方法。 ANSYS MAXWELL 2D用于对变压器进行建模并分析其不同的设计参数。多目标差分进化算法用于查找最小化音量和损耗的最佳设计参数。在本文中，我们介绍了具有特定输入和输出电压规范的1 KVA变压器的最佳设计参数。然后对具有这些最佳设计参数的变压器进行不同的加载条件和功率因数值测试。结果表明，具有统一功率因数的75％加载条件的最大效率。随着功率因数的降低，效率也会降低。
Optimization of design parameters of a transformer is a crucial task to increase efficiency and lower the material cost. This research presents an approach to model a three-phase transformer and optimize design parameters to minimize the volume and loss. ANSYS Maxwell 2D is used to model the transformer and analyze it for different design parameters. The multi-objective differential evolution algorithm is used to find optimum design parameters that minimize the volume and loss. In this paper, we present the optimum design parameters for a 1 kVA transformer with a particular input and output voltage specification. The transformer with these optimum design parameters is then tested for different loading conditions and power factor values. The results show that the maximum efficiency is obtained for 75% loading condition with unity power factor. As the power factor decreases, the efficiency decreases as well.
