摘要
为了提高独立电源系统的质量以满足日益增长的需求,提出了一种基于无刷双馈电机的独立电源系统。首先介绍了无刷双馈电机的结构并分析了其实现变速恒频发电的原理,通过引入坐标变换矩阵,结合静止ABC轴坐标系模型,推导了无刷双馈发电机转子机械速d-q轴的数学模型,最后根据无刷双馈电机在独立电源系统中的应用特点,建立了无刷双馈发电机独立运行时的数学模型。
In order to improve the quality of power supply to meet demands, a kind of stand-slone power supply system based on brushless doubly-fed machine was put forward. Structure of brushless doubly-fed machine is introduced in this paper and it analyzed the principle of the Variable Speed Constant Frequency. Through the coordinate transformation, the d--q model at rotor speed is derived from the static ABC model and according to the characteristics of stand-alone power supply system, the stand-alone mathematical model was established in this paper.
