摘　　要：从电机状态方程出发，提出用饱和电感及其变化率的方法处理同步电机起动时遇到的磁饱和现象，并组建了同步电机全频起动时的数学模型。对影响电机起动的几个重要因素（如线路阻抗、发电机和电动机的励磁电流、发电机的外加机械转矩、发电机的初始角、电动机的摩擦转矩和门漏转矩等）进行了详细仿真分析，并与试验结果进行了比较。As synchronous machine full frequency starting, it is considerable that magnetic field saturation, in this paper, saturated reactance and its rate of change were combined in the equation of electric machine state, the system mode for analyzing starting process was made by the equations of two electric machine state The effects of system parameters such as line resistance, relative excitation on the two machines, initial starting angle, motor friction torque, gate leakage torque and rate of application of torque were studied with simulation and experiment The method that was developed by authors is better to analyze the starting process, thought simulation results were compared with experiment results
