大型电力变压器三维漏磁场与结构件损耗的时域分析
Time Domain Analysis of 3D Leakage Magnetic Fields and Structural Part Losses of Large Power Transformers
摘要
Abstract
A time domain analysis method combining analytical and numerical solutions for material homogenization was proposed to calculate 3D leakage magnetic fields and its structural part losses in the nonlinear and anisotropic laminated core with the sinusoidal excitation. The TEAM Problem 21C-Ml was used as the numerical example to verify this method with the comparison of the losses between the calculated and measured results. This method was applied to the numerical calculation of a DFP-380MVA/500kV single-phase power transformer; and the calculation error of the structural part losses was 6.166%. On the premise of engineering precision, this method can reduce the scale of calculation and make it possible to accurately calculate the structural part losses in large power transformers.关键词
