Latest Patents
Healy's latest patents include innovative methods and apparatuses for controlling wind turbines. One of his notable inventions is the "Torque control for a variable speed wind turbine." This patent discloses a method for controlling the rotor tip speed of a wind turbine to maintain optimal performance. The invention ensures that the rotor tip speed remains below the limiting torque at a selected constant velocity ratio with respect to wind speed. Above the limiting torque, it allows for control of the rotor tip speed at higher speeds, thereby enhancing the turbine's efficiency.
Another significant patent is the "Variable speed wind turbine," which features a frequency converter that transforms variable frequency AC from a turbine-driven AC generator into fixed frequency AC for power grid delivery. This technology is crucial for controlling the power flow from the generator to the grid, optimizing the air gap torque between the generator's stator and rotor. The turbine's speed is adjusted to maximize efficiency by precisely managing the air gap torque based on a defined schedule of generator speed versus generated power.
