零阶方法在特高压变压器线圈电场优化中的应用

摘要

采用有限元分析软件ANSYS的参数化编程语言APDL(ANSYS Parametric Design Language)建立了特高压变压器底部线圈的参数化有限元模型.计算了底部线圈的电场分布,并提取出最大电场强度值.在此基础上,针对线圈结构的参数设计,采用零阶优化方法,对特高压变压器底部线圈的电场进行优化.优化结果表明,采用零阶优化方法优化后,最大电场强度强度值明显降低.%The parametric finite element model of the ultra-high voltage transformer coil is constructed based on the AN-SYS Parametric Design Language (APDL). The electrical field distribution of the transformer bottom coil is calculated and the maximum of electric field intensity is gained. In view of the parametric design of the coil structure, the zero-order optimization method is employed to optimize the electrical field of the ultra-high voltage transformer bottom coil. As a result, the maximum electrical field is greatly decreased by the zero-order optimization method.
