Innovations for Enhancing Power Efficiency From Wind Turbines

A wind turbine design that uses blade oscillation and periodic angle changes to maximize power output from fluid flows like wind and water. The turbine has a vertical blade connected to a counterweight that pivots perpendicular to the fluid flow. Control mechanisms vary the blade angle and rotation to optimize energy capture. The blade's oscillation and angle changes, along with flywheel momentum, extract more energy compared to fixed orientation turbines. The movements are coordinated to follow the fluid flow and avoid disruptive shocks smoothly. The design can be modular for ground, water, or rooftop installations.

Wind turbine system with power split transmission coupling that enables efficient power generation and regeneration. The power split transmission coupling is a variable torque coupling that can divert hydraulic fluid to limit power to the generator when the rotor speed exceeds the generator's rating. The diverted fluid is stored under pressure. When the rotor speed drops below the generator rating, the stored fluid is used to boost generator power via a hydraulic motor. This allows generating the maximum potential power without exceeding the generator rating. The system can capture more power from varying wind speeds by using stored energy during lulls.

The system uses multiple small air storage tanks and compressor-expander trains at each wind turbine rather than large consolidated underground storage. The tanks are connected by a thermal interchange network to share heating and cooling to improve efficiency. The distributed storage and thermal exchange overcome the limitations of centralized compressed air storage systems.
