Parametric Sensitivity Analysis of a hybrid excitation flux switching wind turbine generator

The hybrid excited flux switching synchronous machines (HE-FSM) have several properties used in variable speed applications for both high and low-speed systems. Defined by the number of stator slots and the number of rotor poles, the studied machine is an attractive candidate for wind turbine systems. There are various types of HE-FSMs; nevertheless, the presented machine's topology with a totally active stator and a passive rotor is advantageous in wind turbine applications thanks to the adjustment of the excitation field added to the robustness of the rotor. In this paper, a parametric sensitivity analysis of 24 slots/20 poles HE-FSM is developed for a wind energy conversion system in urban and rural application. The research target is to elaborate a parametric sensitivity study for this machine using finite element analysis method in order to explore its operational behavior and limitations which have to be in line with low-speed ranges. A particular emphasis was placed on some elementary design variables due to their direct impact on the target objectives. The design approach is used to treat several dependent design parameters to achieve the target performances: maximizing the generated power and minimizing the basic speed.
