　　The aim of this thesis is to develop a coordination control between controllable converter and switched excitation capacitors for autonomous wind self-excited induction generators because both output voltage and frequency of an autonomous wind induction generator would be inherently affected by random wind speed and connected loads.

　　In this thesis, the generated AC power source of the studied wind induction generator is converted to a weal regulated DC power source by means of switching power transistors using a digital signal processor (DSP). The controlled DC power source is employed to supply dc loads and inverter which is for producing fixed AC power source.

　　A laboratory 2.2 kW induction generator driven by a brushless DC motor and a TMS320F240 DSP are practically utilized. Three-phase induction- generator model, three-phase controllable converter model, switched excitation-capacitor model are integrated to form complete system dynamic equations for the purpose of obtaining detailed simulations. It can be concluded from the simulated and experimental results that the proposed wind energy conversion system can be practically applied to the studied wind induction generators under various operating conditions.
