Abstract

This paper proposes a fast voltage regulation control method based on direct power calculation. To suppress the issues of long bus voltage recovery time and large voltage fluctuation in dual three-phase permanent magnet generator, firstly, in the voltage outer loop, the fast adjusting component of the inner loop power reference is derived through a direct power calculation method. This approach enhances the dynamic response of the bus voltage. Secondly, to mitigate control errors induced by system losses, a capacitor power compensation method is introduced to generate an error compensation component for the power reference, thereby improving the voltage control accuracy. Finally, the feasibility and effectiveness of the proposed control strategy are validated through both software simulations and experimental tests. In comparison with conventional methods, the proposed strategy provides stronger disturbance rejection and a faster dynamic response, enabling high-performance DC bus voltage control for dual three-phase permanent magnet generator systems.
