带调节绕组的双馈电机电磁机理

Electromagnetism Theory of Doubly-fed Electrical Machine With Adjustment Winding

带调节绕组的双馈电机是近年来出现的一种新型绕线电机,主要应用于高电压,中、大容量风机水泵的电机节能调速,具有节省占地面积、成本低、效率高、接线简单等优点;当其应用于风力发电系统中可大大提高能源的利用率。就带调节绕组的双馈电机的电磁机理进行分析;采用d-q-o坐标变换法确立了电机的数学模型和稳态等值电路模型,并在Simulink环境下进行了仿真,验证了模型的正确性。

The doubly fed electrical machine with adjustment winding is a new wound field motor, main- ly applies in fan and pump speed control of high-capacity motor, especially in high-voltage. It still has the advantages of saving in floor space, low cost and high efficiency and simple wiring. It can greatly improve the utilization of energy in wind power generation. This paper built the mathematical model and steady-state equivalent circuit based on the theory of d-q-o conversion of coordinate. Simulation results confirm the correctness of the model.
