Abstract
Provided is a control circuit of a converter, in particular a power converter of a wind power installation, configured to control the converter in such a way that the converter emulates a behavior of a synchronous machine. The control circuit includes a power module for calculating a power change depending on a detected power and a correction module for setting a power set point, in particular for the converter, depending on the calculated power change.
Claims20
A control circuit of a converter configured to control the converter to cause the converter to emulate a synchronous machine, comprising:
- a power circuit configured to determine a power change depending on a detected power;
- and
- a correction circuit configured to set a power set point for the converter depending on the power change.
The converter as claimed in claim 13, comprising:
- the controller configured to control the converter.
A method for controlling a power converter of a wind power installation to emulate a synchronous machine, comprising:
- detecting a power at an output of the power converter;
- calculating a power change depending on the detected power;
- and
- setting a power set point for the power converter depending on the calculated power change.
