A wind power generator is provided which is configured to take a measure against a decrease in oil temperature which measure requires no new large-capacity power source. A wind power generator (1) including a hydraulic pump (12) configured to be stopped when a wind turbine is shut down further includes a bypass channel (25) branching off from an discharge side channel of the hydraulic pump (12) and connected to an oil tank (11), an electromagnetic valve (26) provided in the bypass channel (25) and opened when the hydraulic pump 12 is started, a temperature sensor (31) configured to detect the oil temperature of hydraulic operating oil, and a controller 30 configured to carry out pump inching after the hydraulic pump (12) has been started, to raise the temperature of the hydraulic operating oil to a predetermined value. |
