摘　　要：利用MATLAB软件中的电力系统模块库(PSB),建立了分析变压器饱和特性的系统仿真模型。使用该模型,对考虑磁滞、剩磁影响时的变压器饱和特性及变压器在空载合闸瞬变过程中励磁涌流及其影响因素、谐波的变化等进行了仿真分析,为分析变压器的特性提供了简单有效的手段。By using power system block set （PSB） of MATLAB, a simulation model applied to analyze the saturation characteristics of transformer is built. By utilizing this simulation model, saturation characteristic of transformer considering hysteresis and remnant flux is analyzed. The paper analyzes the varieties of inrush current and its influence complication, harmonic in the instantaneous changes. This is a simple and effective way to analyze saturation characteristics.
