| 10. | The contributions done are as follows : according to the mathematical model of doubly fed motor and the theory of vector control , a unit power factor of rotor control scheme is proposed . in the doubly fed adjustment system , in order to control magnetic torque of motor this scheme is designed by controlling the reverse direction between rotor voltage and current to keep the vertical direction between rotor current and flux . it is known from theoretical analysis that for partly decoupling this scheme is only effective under sub - synchronization speed , but not control the system and obtain steady state since speed adjustment system ca n ' t adjust the magnitude of rotor flux under sup - synchronization
而传统的无速度传感器双馈调速矢量控制系统，由于采用磁链定向方法，在同步速附近存在较大的工作死区，针对上述问题，本文做了如下的研究工作：本文从双馈电机的数学模型出发，根据矢量控制的基本原理，提出了一种转子侧功率因数为1的双馈电机矢量控制方案的设想，即在双馈调速时采用转子电流定向的方法，并控制外加转子电压与转子电流始终反相，以保持了转子电流与转子磁链矢量垂直，通过控制转子电流的大小来达到控制电机电磁转矩的要求。 |
