Abstract

Recent work has illustrated benefits of the brushless doubly fed generator (BDFG) in wind power generation applications. Coupling capability between the stator main and auxiliary windings is the most significant factor which affects the power density and operation performance of the BDFG. In this paper, the calculation method for the winding inductance parameters are put forward based on winding function. The effect of different design parameters, such as pole numbers, pole- arc factor and winding pitch and so on, on coupling capability is investigated by inductances and their waveforms obtained from above method. It is found the design parameters should be selected appropriately in order to get the optimum coupling inductances and operation characteristics of the BDFG.
