CONSTRUCTION TIME SELECTION DEVICE AND CONSTRUCTION TIME SELECTION METHOD

摘要

An object is to select an appropriate timing for servicing a wind turbine generator (12). In a wind turbine generator system (10), a system managing device (20) determines a servicing timing for replacing or repairing a main component included in the wind turbine generator (12) due to a failure of the main component in accordance with a time point at which the main component may fail, which is predicted on the basis of a temporal change in a detection signal output from a status detector that detects the status of the main component. A servicing planning device (22) selects a servicing timing for the main component on the basis of a servicing suspension rate at which an average wind speed at a location where the wind turbine generator (12) is installed becomes higher than or equal to a predetermined threshold value at which servicing of the component is not possible, the timing being selected with reference to the determined timing.
