Investigations of Grid-Connected Wind Power System – Low Voltage Ride Through and Power Quality Issues

Abstract: This thesis presents an investigation on system architecture, control and analysis of wind turbine generators to improve grid integration performance. First of all, the main grid connection requirements have been reviewed in terms of safety operation of transmission systems as well as the wind turbine configurations. Due to these requirements, there have been conscious efforts made by wind turbine manufacturers to design grid compatible wind turbines, which are able to improve turbine operating performance and eliminate negative impacts on the utility, with features such as strong fault ride- through capability, flexible voltage regulation and good power quality performance.
