Abstract In this short communication, we intend to introduce an off-line coupled simulation method (OCM) framework for the DC biased power transformer performance assessing. The OCM combined with the electromagnetic transient (EMT) and finite element method (FEM) simulation, which can benefit from fast calculating excitng current and deail representing the transformer’s internal performance. It can be concluded from the numerical results of single-phase and three-phase transformers that it’s feasible to estimate the transformer performance under DC bias condition with the proposed OCM framework, and it’s quite promising in engineering application.

直流偏置条件下变压器性能评估的离线耦合仿真方法

摘要 在这篇简短的交流中,我们打算介绍一种用于直流偏置电力变压器性能评估的离线耦合仿真方法 (OCM) 框架。OCM 结合电磁瞬态 (EMT) 和有限元法 (FEM) 模拟,可以从快速计算励磁电流和代表变压器内部性能的细节中受益。从单相和三相变压器的数值结果可以得出结论,用所提出的OCM框架估计直流偏置条件下的变压器性能是可行的,在工程应用中很有前景。
