Switched reluctance machine has various desirable features, which comes from its simple construction. They are the wide speed range, high temperature operation and small moment of inertia, constant frequency irrespective of load or capacitance variations with good efficiency and improved voltage regulation. It is possible to use it as a wind driven alternator which may be connected to the common network. The steady-state analysis of the reluctance generator based on d-q axes transformation is carried out, with the saturation effect as an essential element. The required capacitance in the different operating conditions is determined to satisfy the main requirements of constant voltage for a loaded reluctance generator. This system proposed feasibility and validity are simulated on MATLAB/SIMULINK.
