Abstract :
The brushless doubly-fed machine is the most effective type of electrical machine suitable for driving windmills or water pumps to perform speed-adjusting, energy-saving operation, which make give it very good application prospects. In this paper, the practical mathematical model for a cascade brushless doubly-fed machine was derived in detail and the validity of the model was verified by numerical simulation as well, which provides the theoretical foundation for the study of control strategy and its implementation in further investigation
