摘要
由于没有电刷和滑环,提高了运行的可靠性,降低了维护成本,因此无刷双馈电机(BDFM)在变速恒频发电领域有着广阔的应用前景。由于特殊的结构和工作原理,BDFM数学模型十分复杂。从BDFM多回路空间矢量数学模型出发,推导出了两个静止坐标系之间的坐标变换关系以及功率绕组静止坐标系数学模型和控制绕组静止坐标系数学模型,推导过程简洁明了。所得结果为BDFM理论分析和不同控制策略的研究提供了理论基础。MATLAB/Simulink环境下的仿真结果验证了数学模型及坐标变换关系的正确性。
The brushless doubly-fed motor(BDFM),without a brush gear,provided the benefits of low maintenance cost and high reliability,so it had broad application prospects in the field of variable-speed constant-frequency(VSCF)wind power generation.Because of its special structure and principle of operation,the mathematical models of BDFM were very complicated.Based on multi-loop space vector model of BDFM,a new method to derive static reference frame models of the power winding and the control winding was proposed,and the coordinate conversion between them was given.The derivation was simple and clear.The conclusions provided a theoretical basis for the theoretical analysis and control strategy of BDFM.The simulation results in MATLAB/Simulink showed that the static reference frame models and coordinate transformation were correct.
