【摘要】 用电机状态方程的形式，研究了与抽水蓄能电机背靠背启动有关的机电变化规律．为使电机能在合理的状态下进行背靠背启动，对电机的励磁电流、摩擦转矩、门漏转矩和发电机的驱动转矩及电机的初始角等影响因素分别进行了仿真分析，并确定了其应选值范围．更多还原

【Abstract】 The electrical and mechanical rules of conversion are studied with the equations by the two unit states about back to back starting of pump storage unit. The effects of system parameters such as relative excitation on the two units, initial starting angle, motor friction torque, gate leakage torque and application of torque were analyzed with simulation, for pump storage unit normal starting.更多还原
