Problems solved by technology

Here, however, there is the problem that large power stations also lose their role in stabilizing the grid as they are cut off and "disconnected from the grid"
Furthermore, if only a limited possibility of reacting quickly to the prevailing wind conditions is provided, this hinders or makes it difficult to implement grid stabilizing effects

Embodiment Construction

[0042] figure 1 A wind energy installation 100 is shown with a tower 102 and a nacelle 104 . A rotor 106 with three rotor blades 108 and a spinner 110 are arranged on the nacelle 104 . In operation, the rotor 106 is brought into rotational motion by the wind to drive a generator in the nacelle 104 .

[0043] figure 2 A wind farm 112 is shown with three exemplary wind energy installations 100 , which can be identical or different. The three wind energy installations 100 thus basically represent any desired number of wind energy installations of wind park 112 . The wind energy installation 100 supplies its power, ie in particular the generated electric current, via the wind park grid 114 . In this case, the respectively generated currents or powers of the individual wind energy installations 100 are summed, and a transformer 116 is usually provided, which boosts the voltage in the field for subsequent feeding into the power supply network 120 at the grid connection point 11...

Abstract

The invention relates to a method for the operation of a wind energy installation (100) and / or a wind farm (112) for supplying electric power to an electrical supply system (120), wherein output power, particularly active and / or reactive power (Q, P), is regulated by means of at least one power regulation module (501) of a regulatory and / or control device (131), having the steps of: prescribing a power regulation input value, determining a power regulation output value from the power regulation input value, and outputting a power regulation output value. According to the invention, the power regulation module has a P controller and an I controller and has an I-component limiter, wherein a first operating value of the power regulation input value is processed in the P controller to form a P component, a second operating value of the power regulation input value is processed in the I controller to form an I component, and a third operating value of the power regulation input value is processed in the I component limiter to form a limited I component, and the power regulation output value (P-Output) is determined using the limited I component and the P component.

Description

technical field [0001] The invention relates to a method for operating a wind energy installation and / or a wind park and a regulating and / or control device for operating a wind energy installation and / or a wind park. Furthermore, the invention relates to a wind energy installation and a wind park. Background technique [0002] Generally speaking, a wind energy installation and / or a wind farm can be defined as a wind energy generator, ie an energy generating installation for generating energy from wind energy, which is designed in particular to feed electrical power into a power supply network. [0003] It is known to generate electrical power with the aid of wind energy installations and to feed it into a power supply network. Corresponding wind energy installations, i.e. individual wind energy generators are schematically located at figure 1 shown in . Increasingly, instead of individual installations, a plurality of wind energy installations are also installed in wind f...
