Title:
RENEWABLE ENERGY-TYPE ELECTRIC POWER GENERATION DEVICE AND ROTOR AFFIXATION METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2013/042279
Kind Code:
A1
Abstract:
A renewable energy-type electric power generation device (1) is provided with: a rotor (2) having rotating blades (2A), a hub (2B), and a main shaft (2C); a variable displacement hydraulic pump (20) driven by the rotation of the rotor (2); a hydraulic motor (22) driven by hydraulic oil having pressure increased by the hydraulic pump (20); and a generator (6) connected to the hydraulic motor (22). A rotor affixation method for the renewable energy-type electric power generation device (1) is provided with: a step which stops the rotor (2) by causing a braking force by at least the hydraulic pump (20) to act on the rotor (2); and a step which, after the step for stopping the rotor (2), affixes the rotor (2) so that the rotor (2) does not move in the rotational direction. In the step for stopping the rotor (2), the torque of the hydraulic pump (20) is changed to adjust the braking force applied to the rotor (2).
