A vortex generator for a wind turbine blade includes: a platform portion to be fixed to a surface of the wind turbine blade; and at least one fin erected on the platform portion. The platform portion includes marks disposed on a pair of opposite positions in an outer edge region of the platform portion and indicating orientation of the vortex generator.

Vortex generator for wind turbine blade, wind turbine blade, wind turbine power generating apparatus, and method of mounting vortex generator

A method of mounting a vortex generator to a wind turbine blade includes: a step of specifying positions of at least two reference points at different coordinates in a blade spanwise direction of the wind turbine blade on the wind turbine blade; and a step of adjusting a mounting direction of the vortex generator and mounting the vortex generator to the wind turbine blade, with reference to a line connecting the reference points. The step of specifying the positions of the reference points comprises specifying the position of each of the reference points on the basis of: a length along a surface of the wind turbine blade in a chordwise direction from a trailing edge of the wind turbine blade or from a blade spanwise directional line extending along the blade spanwise direction on the surface of the wind turbine blade; and a distance in the blade spanwise direction from a blade root or from a blade tip of the wind turbine blade.

It is an object to reduce influence on a utility grid by reducing a rapid change in active power, and to extend the life of a wind power plant while controlling active power output in response to a request from the utility grid. A monitoring and control apparatus applied to a wind power plant including a plurality of wind turbine generators includes an electric power control unit that controls the wind turbine generators so as to reduce output of the wind power plant in a stepwise manner, when an active power reduction request from a utility grid side is output.
