Title:
WIND-POWERED POWER GENERATION FACILITY AND DEGREE-OF-DAMAGE DIAGNOSIS DEVICE FOR WIND-POWERED POWER GENERATION FACILITY
Document Type and Number:
WIPO Patent Application WO/2016/042652
Kind Code:
A1
Abstract:
Provided is a wind-powered power generation facility in which by estimating the wind speed at individual locations on a wind turbine on the basis of a wind speed meter and other sensor information, degree-of-damage diagnosis can be performed at each location without providing sensors any more than necessary. The wind-powered power generation facility includes a rotor comprising a hub and a plurality of blades, and receives wind with the rotor to thereby convert the wind to electrical energy, wherein the following are provided: a wind speed meter that is disposed at a prescribed location in the wind-powered power generation facility; a plurality of sensors that are disposed at a plurality of locations that constitute the wind-powered power generation facility, and that detect the operation state of the wind-powered power generation facility; and an individual-location wind speed calculation device that calculates the wind speed at each location that constitutes the wind-powered power generation facility on the basis of the wind speed values measured by the wind speed meter and detection data detected by the plurality of sensors. The wind-powered power generation facility is characterized in that the individual-location wind speed calculation device calculates the wind speed at individual locations of the wind-powered power generation facility by using a individual-location wind speed calculation table that includes operation state data of the wind-powered power generation facility and location data of the wind-powered power generation facility.
