Abstract
To Reduce emission, much effort has been devoted to the development of green energy techniques. Among the various types of green energy generations, wind energy conversion is studied in thesis.
Squirrel-cage induction generators have been widely employed for wind energy conversion due to their low costs and high reliability. However, the squirrel-cage induction generators are not capable of providing voltage regulation due to the lack of rotor excitation.
To improve the reactive power support and voltage regulation of a squirrel-cage induction generator, a dynamic voltage regulator（DVR） is designed in this thesis. Through the generation or absorption of reactive power, the DVR is capable of stabilizing the generator terminal voltage and the load voltage when the system is subject to load changes or wind speed variations.
The effectiveness of the proposed DVR is demonstrated by computer simulations using MATLAB○R/Simulink/SimPowerSystems.
