PROBLEM TO BE SOLVED: To restrain slippage (in vainl) of a frictional plate of a clutch interposed in a power transmission system of a power generator of a wind power generation facility and to extend the life of the clutch to that extent.SOLUTION: In a control method for a power transmission system of a wind power generation facility which is provided with a clutch capable of adjusting slip torque by press force of a frictional plate, in the power transmission system from a blade of the wind power generation facility to a power generator, the power transmission system is provided with the clutch 10 capable of adjusting slip torque by press force of the frictional plate, and the control method includes a process (steps S12, S14) of pressing the frictional plate with the first pressurized fluid Pr1 capable of generating the first press force which can maintain the frictional plate of the clutch 10 in a connection state while axial torque input to the clutch 10 is less than predetermined allowable transmission torque, and a process (Yes in step S12) of detecting slippage of the frictional plate, and a process (step S20) of pressing the frictional plate with the larger second pressurized fluid Pr2 to increase the press force of the frictional plate larger than the first press force after slippage of the friction plate has been detected. |
