摘要
根据无刷双馈电机的特点 ,将功率绕组和控制绕组在各自的同步坐标系下分别进行磁场定向 ,获得了简化的数学模型和转子磁场定向控制策略 ,给出了基于这一方法的系统框图和基于 80 196KC的硬件结构图 ,并对系统进行了仿真和试验研究 。
The brushless doubly fed machine(BDFM) has gained renewed attention in variable speed drive applications in recent years for the features of simple structure,favorable characteristics and economical operation.In this paper,the implementation of field orientation control strategy of a BDFM for adjustable speed drives is presented.With the help of a double synchronous reference framed q model,a rotor flux orientation scheme is employed to achieve decoupled control of torque.A 30kW BDFM prototype system with 80196KC single ship based controller and a bi directional power converter is built to verify the theoretical analysis.Computer simulation and laboratory experimental results are shown in favorable agreement.
