    摘要： It is intended to provide a power generating apparatus of renewable energy type that has a fixation structure of the hydraulic pump that can transmit large torque and can be processed with ease and at low cost even when the main shaft has a large diameter, as well as a method of installing such hydraulic pump. In the power generating apparatus, a connecting member 20 is provided on the outer periphery of a main shaft 4 to engage with a cylindrical member 10 provided on the outer periphery of the main shaft 4. The connecting member 20 includes a fixing part 21, a first spline part 22 and first pins 23. The fixing part 21 is fixed to the outer periphery of the main shaft 4 by means of the first pins 23 disposed along a circumferential direction of the main shaft 4. The first spline part 22 extending at other end of the fixing part 21 on a rear-end side, has a clearance S between the outer periphery of the main shaft 4 and the first spline part 22 and first spline teeth 24 formed on an inner periphery facing the clearance S. The clearance S opens at the end of the fixing part 21 on the rear-end side.

    摘要： A method of operating a wind turbine generator which including a drivetrain (8) for transmitting rotation energy of a wind turbine rotor (4) to a generator (6), the drivetrain (8) including an oil using unit (10); a storage tank (12) for storing oil supplied to the oil using unit (10); and a circulation line (14) through which oil circulated between the storage tank (12) and the oil using unit (10) flows, includes an oil-leakage determination step of determining whether oil leakage from the oil using unit (10) has occurred, using the first oil-leakage determination condition including both of following conditions a) and b). In the oil-leakage determination step, it is determined that the oil leakage from the oil using unit (10) has occurred if any one of the following condition a) or b) is not satisfied. Condition a): a fluid level of the oil in the storage tank (12) is greater than a threshold value. Condition b): a pressure in the circulation line (14) is greater than a threshold value, or a pressure in the oil using unit (12) is greater than a threshold value.
