Embodiment Construction

[0078] figure 1 A schematic diagram of a wind energy installation 100 according to one embodiment is shown.

[0079] For this purpose, the wind energy installation 100 has a tower 102 and a nacelle 104 . An aerodynamic rotor 106 with three rotor blades 108 and a spinner 110 is arranged on the pod 104 . In operation, the rotor 106 is brought into rotational motion by the wind to drive a generator in the nacelle 104 .

[0080] The generator is connected by means of a converter to a power grid, for example a wind farm grid or a power grid, in order to feed in three-phase alternating current.

[0081] For this purpose, the wind energy installation includes the control unit described above or described below.

Abstract

The present disclosure relates to a method for operating a converter on a three-phase electrical power supply grid, the method comprising the following steps: operating the converter in a first operating mode by means of a control unit for generating an output current, wherein the converter in the first operating mode operates in such a way as to apply a voltage to the electrical power supply grid; detecting a grid fault on the electrical power supply grid by means of a detection means during the first operating mode; limiting the output current of the converter by means of current limitation when a grid fault on the electrical power supply grid has been detected during the first operating mode, in particular in such a way that the output current of the converter falls below a predetermined maximum current or substantially corresponds thereto.

Description

technical field [0001] The invention relates to a method for operating a converter, in particular a wind power plant, and a wind power plant comprising such a converter. Background technique [0002] As regenerative, converter-based generators increasingly crowd out traditional power plants operated with synchronous generators, classic synchronous generators are increasingly losing their influence in the supply grid. [0003] Due to this retrogression of the synchronous generator, the quality of conventional flywheels stabilizing the power supply network is also reduced. [0004] Since the effect of such changes in the supply network has hardly been studied, there is the idea of ​​operating the converter of the regenerative generator in such a way that the regenerative generator operates with an applied voltage at the supply network and / or Or act like a traditional synchronous machine. [0005] In other words, the converter should act on the supply network like a conventio...
