Method for controlling a wind energy turbine of a wind park comprising multiple wind energy turbines

Abstract

The method for controlling a first wind energy turbine of a wind park comprising multiple wind energy turbines connected to the grid, in situations where the first energy turbine operates substantially at zero energy output level, comprises the steps of determining whether at least one of the other wind energy turbines of the wind park is operated above a predetermined energy output level, and if at least one of the other wind energy turbines of the wind park is operated above the predetermined energy output level, maintaining connection of the first wind energy turbine to the grid.

Description

technical field [0001] The invention relates to a method of controlling a wind turbine in a wind park with several wind turbines, in particular a method of optimized wind park management with automatic wind turbine control. Background technique [0002] Controlling wind turbines operating in calm wind conditions can keep the wind turbines in grid-connected rotation (electric mode), but this requires frequent switching operations of the wind turbines or consumes more energy. The purpose of this is to allow the turbine system to extract as much energy as possible from the wind. The grid tie switch which connects and disconnects the generator of the wind turbine to the grid has a limited service life due to mechanical wear and tear. Under the condition of calm wind, the more frequent the action of the grid-connected switch, the more energy will be consumed. According to the variation of wind speed characteristics, turbulence, controller structure and parameter setting, the nu...
