摘　　要：为了研究不同脉宽调制策略对采用矢量控制的船用大功率永磁电机变频调速性能的影响,通过对大功率永磁电机稳态运行空间矢量图的分析,结合4 088 kW永磁电机的电气性能参数,计算电机定子电阻、电感等关键数值。依据电机参数,建立三种基于正弦脉宽调制、电流滞环跟踪控制和空间矢量脉宽调制策略的仿真模型。仿真结果表明,采用空间矢量调制策略时,电机动态转矩和转速的响应时间最短,电流滞环跟踪策略次之,正弦脉宽调制最差。船用大功率永磁电机矢量控制变频调速系统可综合考虑选择电流滞环跟踪控制和空间矢量脉宽调制策略。To research the performance behavior of the speed regulating system used the different pulse width modulation（PWM） strategy in the vector control system for marine larger power permanent magnet synchronous motors（PMSM）,it calculated the value of stator resistance and inductance by analyzing the space vector graph in the steady state operation and the electrical performance parameters of a 4 088 kW PMSM.Based on the parameters of the motor,it established the vector control simulation model system used modulation strategy of current hystersis PWM,sinusoidal PWM and space vector PWM.The simulation results show that in the response time of the dynamic torque and speed,the space vector PWM is the fastest,the current hystersis PWM takes second place and sinusoidal PWM is the slowest;The methods of using current hystersis PWM and space vector PWM are suitable for the marine larger power PMSM variable frequency speed regulation system.
