| 摘 要： | 利用MATLAB软件中的电力系统模块库（PSB）,建立分析变压器仿真系统模型。利用这一模型,对磁滞的变压器在空载合闸瞬变过程中涌流和短路电流进行仿真分析。结果表明,变压器铁心的磁滞对涌流影响较大,特殊情况下,涌流可与短路电流相比拟,为变压器保护装置的正确选择提供参考依据.

| Abstract: | Using power system block set(PSB) of MATLAB,a simulation model applied to analyze the saturation characteristics of transformer is built.Utilizing this simulation model,saturation characteristics of transformer considering hysteresis are analyzed.It analyzes the varieties of inrush current and short-circuit current.The results show transformer core has greater impact on the inrush current,and in special circumstances,the inrush current and short circuit current can be compared.It can provide reference for t... |
