With a total of 15 patents to his name, Harner has made strides in developing innovative solutions that enhance the efficiency and effectiveness of wind turbines.
Latest Patents
Among his latest patents 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 utilizes an electronic cycloconverter or rectifier-inverter to manage power flow from the AC generator to the grid, thereby controlling the air gap torque between the generator stator and rotor. The turbine speed is optimized to improve efficiency by precisely regulating the air gap torque based on a defined schedule that correlates sensed generator speed with sensed generated power. Another significant patent is the "Blade Pitch Angle Control for Large Wind Turbines," which introduces an advanced control system that provides a minimum pitch angle reference signal for desired blade pitch at wind velocities below rated levels. This system incorporates signals indicative of generated power or torque and the rotational frequency of the wind turbine rotor, allowing for improved performance.
