  • Patent number: 10724502
    Abstract: A vertical axis wind turbine with improved safety, production efficiency and greater functional wind speed range. A vertical axis wind turbine comprises turbine blades having geometric characteristics of a “yin yang” symbol when viewed from the top down. The turbine blades are configured to form a scoop portion for catching wind. The surface area of the scoop portion may be dynamically configured to accommodate power production in higher wind speed ranges by dynamically furling the blades to reduce the surface area of the scoop portion as RPM begins to exceed a safe limit. First and second permanent magnet rotor arrays are dynamically positioned above and below an array of stator coils to maximize power generation.

  • Patent number: 10711765
    Abstract: A method is provided for controlling a wind turbine that has a generator that is controlled via a converter in a boost operation, in which an electrical power that is fed into an electrical transmission network is increased via a generative deceleration of the generator. The method comprises using a control to determining a set point value for a generator torque depending on an actual value of a rotational speed. The determined set point value for the generator torque is applied to a generator via a limiter with a predefinable upper and lower limit. Determining the set point value for the generator torque in boost operation that leads to an increased fed-in electrical power in response to a boost signal; and limiting a temporal change of the set point value for the generator torque in a recovery operation in response to a recovery signal.
