Dynamic control of series connected wind turbine generating system

Dynamic control for a wind turbine generating system consisting of series connected five wind generators and a current source thyristor inverter is discussed. It is shown that tip speed ratios of the individual turbine can be controlled almost constant at an optimum condition with the proposed method, making an effective operation of the system possible. Experimental investigations are also discussed for a system with two wind turbines to verify the usefulness of the proposed generating system.
