Embodiment Construction

[0035] figure 1 A horizontal axis wind turbine is shown, as is basically known from the prior art. According to the present invention, figure 1 The horizontal axis of the wind energy plant is equipped with a method, namely the operation management method according to the invention.

[0036] figure 2 Two operating characteristic lines, ie two speed-power-characteristic lines, are shown schematically. In this diagram, the optimal operating characteristic line 1 is represented by a solid line and not the optimal operating characteristic line 2 by a dotted line. The two operating characteristic lines 1 and 2 represent only a schematic curve which may differ from the actual curve. In particular, the actual curve may differ from the simplified straight line description. This description should basically clarify the relationship between the optimal operating characteristic line 1 and the non-optimal operating characteristic line 2 . Besides this, this also applies to image 3...

Abstract

The present invention relates to a method for controlling a wind turbine generator system that is connected to an electrical power system and has a generator with an aerodynamic rotor of variable speed, in which the wind turbine generator system can be operated at an operating point with an optimal speed with respect to prevailing wind conditions, wherein the wind turbine generator system is operated for a transitional period of time or for a sustained period of time at a non-optimal operating point with a non-optimal speed, and the non-optimal speed is greater than the optimal speed.

Description

technical field [0001] The invention relates to a method for controlling a wind energy installation and a corresponding wind energy installation. Background technique [0002] Wind energy installations are generally known and are used to capture kinetic energy from the wind and convert it into electrical energy in order to feed this electrical energy into the grid. The task of wind energy installations today is also to support the grid into which the wind energy installations are fed. [0003] A frequency-dependent power regulation is thus described, for example, in German patent application DE 10022974A1 from 2000 (published on 22 November 2001). Accordingly, it is provided that, with increasing grid frequency, the power input of the wind energy installation into the grid is reduced as soon as the grid frequency has exceeded a limit value. [0004] Consider therefore the case of a grid in which there is an energy surplus, which due to the behavior of large power plants le...
