Coordinated control method and system for lubrication-by-cluster of wind turbine group

Abstract

The present invention belongs to the technical field of wind power generation, and provides a coordinated control method and system for lubrication-by-cluster of a wind turbine group, the method including: acquiring a time interval for a lubrication action on a wind turbine; calculating a duration between a current time point and a last lubrication action on the wind turbine, and determining whether the wind turbine has a lubrication action requirement based on the time interval and the duration; when the wind turbine has the lubrication action requirement, constructing a wind turbine lubrication queue; and in combination with a current operating state and generated power of the wind turbine group, controlling different wind turbines in the wind turbine group to execute the lubrication action requirement according to the constructed wind turbine lubrication queue, thereby completing coordinated control of the lubrication-by-cluster of the wind turbine group.
