摘要
本文基于瞬时无功功率理论,并在对矢量控制及直接转矩控制两种思想进行研究的基础上,提出了一种三相鼠笼式异步电动机的瞬时功率控制方案,分析了其瞬时功率;通过Matlab/Simulink平台,建立了异步电动机瞬时功率控制方案模型,实现了电机有效控制,仿真实验验证了控制方案的有效性。
This paper proposes an instantaneous power control scheme of three-phase squirrel-cage asynchronous motor, and its instantaneous power is analyzed, based on the theory of instantaneous reactive power, and based on the research of vector control and direct torque control, The instantaneous power control scheme model of induction motor is established by Matlab/Simulink platform, and the effective control of the motor is realized. The simulation experiment verifies the effectiveness of the control scheme.
