摘要 采用直流法、交流相量法与相变量仿真法解决了光伏水泵系统用永磁无刷直流电动机动静态特性的分析问题。着重分析了电压型逆变供电无刷直流电动机的调速与转矩特性以及用相变量仿真计算的动态特性。获得了逆变器触发角跟随整定及电流滞环控制等准则。 This paper presents the structure of the brushless DC motor with rare earth magnet excitation and indicates that the brushless DC motor has more advantags than the asynchronous motor in the photovoltaic pump system. Using DC circuit method and AC phasor method, the performance of the speed and the torque of the brushless DC motor with voltage inverter can be analysed. Using the mathematic model of phase variable, the simulation of dynamic performance of the motor is worked out. Hence, the principles of the optimal control for the photovoltaic pump system is obtained.
