摘要
介绍励磁涌流产生的原因及特点,以单相变压器为例,利用PSCAD软件建立具有饱和特性的变压器仿真模型,考虑合闸时间、剩磁等因素对变压器励磁涌流的影响并进行仿真.结合谐波分析将仿真结果与理论研究对比,表明采用的仿真分析简单有效,为变压器励磁涌流的识别与解决提供了基础.
The causes,characteristics and impact of inrush current were briefly introduced.By using powers system blockset of PSCAD,a simulation model was built to analyze the saturation characteristics of transformer.Taking the single-phase transformer for an example,a simulation model of the transformer with saturation characteristics was built by PSCAD software.The model simulated the varieties of inrush current and the influence in the different close time.Compared with simulation results and theoretical research results combined with harmonic analysis,the results showed that simulation analysis was simple and effective.This will provide the basis for the identification and settlement of inrush current of transformer.
