Abstract
Described is a power generating apparatus and a rotor locking method for the apparatus, which is capable of locking the rotor without using a huge braking mechanism. The power generating apparatus of renewable energy type includes a blade, a rotor including a hub and a main shaft, a hydraulic pump of variable displacement type driven by rotation of the rotor, a hydraulic motor driven by operating oil pressurized by the hydraulic pump, and a generator coupled to the hydraulic motor. The rotor locking method for the power generating apparatus may include the steps of: decelerating the rotor by adjusting a pitch angle of the blade: after the decelerating step, stopping the rotor by applying a braking force by the hydraulic pump to the rotor; and locking the rotor so that the rotor is immovable in a rotation direction.
