Abstract Three topological transformer models for low-frequency transient simulations are considered in increasing order of their topology. It is first shown that the well-known hybrid model is not a strictly topological one, but despite this, it can be used in many applications. The next is the simplified model, which is a strict electric equivalent of the popular magnetic model, and the last is a detailed electric model, which takes into account thicknesses of transformer windings. This model improvement allows one to reproduce experimentally observed behaviors of the magnetic fluxes in the legs and yokes under short circuit conditions.

混合和拓扑变压器模型的结构和特性

摘要 三种用于低频暂态仿真的拓扑变压器模型按其拓扑的递增顺序考虑。首先表明众所周知的混合模型不是严格的拓扑模型,但尽管如此,它仍可用于许多应用。下一个是简化模型,它是流行的磁模型的严格电气等效模型,最后一个是详细的电气模型,它考虑了变压器绕组的厚度。这种模型改进允许人们在短路条件下重现实验观察到的腿和轭中磁通量的行为。
