Arrangement for generating a control signal for controlling a power output of a power generation system

摘要

An arrangement for generating a control signal for controlling a power output of a power generation system, such as a wind turbine, is provided. The power output is supplied to a utility grid. The arrangement includes a first input terminal for receiving a first input signal indicative of an actual grid frequency of the utility grid, a control circuit for generating the control signal, and an output terminal to which the control signal is supplied. The control circuit includes a bang-bang controller for generating a first power signal being indicative of a predefined amount of power to be added to the power output of the power generation system. The bang-bang controller is adapted to be activated when the first input signal falls below a first predefined threshold. The control signal depends on the first power signal.

1. An arrangement for generating a control signal for controlling a power output of a power generation system, wherein the power output is supplied to a utility grid, the arrangement comprising:
a first input terminal for receiving a first input signal indicative of an actual grid frequency of the utility grid; a control circuit for generating the control signal; and an output terminal to which the control signal is supplied; wherein the control circuit comprises a bang-bang controller for generating a first power signal being indicative of a predefined amount of power to be added to the power output of the power generation system, wherein the bang-bang controller is adapted to be activated, when the first input signal falls below a first predefined threshold, and wherein the control signal depends on the first power signal; further comprising a load determination unit for determining a load of the power generation system, based on the control signal and/or based on both a power output and a nominal power output of the power generation system; wherein the load determination unit comprises a counter for counting a number of times the control signal caused an increase of the power output of the power generation system.
