Excitation Synchronous Wind Power Generators With Maximum Power Tracking Scheme

This paper presents a novel excitation synchronous wind power generator (ESWPG) with a maximum power tracking scheme. The excitation synchronous generator and servo motor rotor speed tracks the grid frequency and phase using the proposed coaxial configuration and phase tracking technologies. The generator output can thus be directly connected to the grid network without an additional power converter. The proposed maximum power tracking scheme governs the exciter current to achieve stable voltage, maximum power tracking, and diminishing servo motor power consumption. The system transient and static responses over a wide range of input wind power are examined using simulated software. Experimental results from a laboratory prototype ESWPG demonstrate the feasibility of the proposed system.
