摘要
分析变压器零序涌流的产生机理及特点,推导出零序涌流高次谐波表达式及零序涌流谐波系数。通过仿真模拟不同因素,对零序涌流高次谐波及零序涌流谐波系数的影响进行定量分析。
The generation mechanism and characteristics of zero-sequence inrush current in transformer are analyzed, the high-order harmonic expression and harmonic coefficient of zero-sequence inrush current are derived. The influence of different factors on the high-order harmonics of zero-sequence inrush current and harmonic coefficient of zero-sequence inrush current is analyzed by simulation.
