Hybrid-Driven Wind Power Generation
Conventional turbines rely on a single electrical or mechanical drivetrain and struggle to balance efficiency with reliability across wide wind-speed ranges. This research proposes a hybrid-drive scheme that integrates electric actuation with hydraulic/mechanical transmission paths in one drivetrain, using intelligent mode switching and power-split control to maintain high capture efficiency at low-to-medium speeds while safeguarding the drivetrain at high speeds.
Key Research Topics
Establishes a dual-channel electric-hydraulic topology and studies optimal power distribution and switching boundaries across wind-speed bands.
Builds electromechanical-hydraulic coupled models and designs bumpless mode-switching and torque-coordination strategies to avoid power shocks during transitions.
Quantifies annual energy production gains and load reductions versus single-mode drivetrains over the full wind spectrum, validated on prototypes.
