Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 94 === This thesis analyzes performance of a grid-connected wind induction generator with pitch controller design using pole-assignment technique. Both time-domain and frequency-domain approaches are employed to systematically examine the robustness of the proposed pitch controller under various wind speeds. The models for wind turbine, induction generator, and transmission line are combined to establish the complete state-space equations of the studied system under three phase balance loading conditions. Blade’s pitch angle, wind shear, wind direction, height of wind tower, length of blade, air density on steady-state characteristics of the studied system are also examined. Dynamic characteristics of the studied wind induction generator subject to disturbance and faulted conditions are explored. Finally, sensitivities and participation factors are both utilized to investigate the relations among system parameters, eigenvalues, and state variables of the studied system.
