摘要:为了实现电机启动中能耗的再利用,分析了电机机械特性和转矩与转差率关系,推导出电机保持最大恒转矩起动时转子上电流变化规律。采用不可控整流电路与可控电流源相结合,取代电机启动时转子上串接的电阻,避免了大量电能以热能形式在电阻上损耗掉。可控电流源通过Boost电路实现;在启动过程中,可以将Boost电路吸收的能量通过逆变输出至电网或其他交流负载,从而达到节能的目的。仿真结果表明,电机具有最优的起动效果。

Abstract: Aiming at realizing the reutilization of energy in the motor starting, the mechanical properties and electrical torque with slip were analyzed, the current variation was derived when the motor starting with constant torque and keeping the maximum. Using noncontrolled rectifier circuit combined with the controlled current source to replace the resistance on rotor when the motor starting, a lot of energy loss on resistance with the form of heat was avoided. Controllable current source can be realized with Boost circuit. During the startup, the energy that Boost circuit absorbed can be sent to the power grid through the inverter, the energy saving was achieved. The simulation results indicate that the motor starting has the best effect.
Key words: constant torque; slip; controlled current source; energysaving; Boost
