摘　　要：针对双三相永磁发电机整流系统施加突变负载时,采用传统电压功率双闭环控制时存在的系统母线电压恢复时间长、电压波动大等问题,提出了一种采用直接功率计算的双三相永磁发电机快速稳压控制方法。首先,在电压外环上,采用直接功率计算的方法得到系统内环功率参考值的快速调节分量,提高母线电压的动态性能。其次,考虑到由系统损耗引起的控制误差,采用电容功率补偿得到功率参考值的误差补偿分量,提升母线电压的控制精度。最后,通过软件仿真和试验,证明了所提控制策略的可行性和有效性。和传统控制方法相比,所提方法具备更强的抗负载扰动能力和更快的动态响应速度,有助于实现双三相永磁发电机系统直流母线电压的高性能控制。To solve the problems of long bus voltage recovery time and large voltage fluctuation in the traditional voltage and power double closed loop control when the mutational load is applied to the rectifier system of dual three-phase permanent magnet generator,a fast voltage regulation control method of dual three-phase permanent magnet generator with direct power calculation is proposed.Firstly,on the voltage outer loop,the method of direct power calculation is used to obtain the fast adjustment component of the system inner loop power reference value to improve the dynamic performance of the bus voltage.Secondly,due to the control error caused by the system loss,the capacitor power compensation is used to obtain the error compensation component of the power reference value to improve the control accuracy of the bus voltage.Finally,the feasibility and effectiveness of the control strategy proposed are proved by software simulation and experiment.Compared with the traditional control method,the proposed method has stronger anti-load disturbance ability and faster dynamic response,which is helpful to realize the high performance control of the DC bus voltage of the dual three-phase permanent magnet generator system.
