Abstract
A wind park comprising at least two wind turbines that produce electrical power by means of a wind rotor and a generator and delivers this to an accumulating network, and comprising a park master that is configured to control said wind turbines and has a power regulator whose input is supplied with a target power signal and, at whose output, power control signals are emitted for the wind turbines, said power regulator comprising a feed-forward control module that imposes a value for the target power onto the output of said power regulator by means of a multiplication element.
Claims18
A wind farm comprising at least two wind turbines configured to generate electric power using a wind rotor and a generator and output the electric power to a busbar grid, and a farm master configured to control the wind turbines, wherein the farm master includes a power regulator comprising an input for a setpoint power signal and an output for power control signals for the wind turbines, wherein the power regulator comprises a feed-forward control module configured to apply a measure of the setpoint power to the output of the power regulator via a multiplication element, wherein the feed-forward control module comprises a fast forward channel for directly outputting the measure of the setpoint power signal received at an input of the feed-forward control module.
A method for operating a wind farm that includes at least two wind turbines configured to generate electric power using a wind rotor and a generator and output the electric power to a busbar grid, and a farm master configured to control the wind turbines, wherein the farm master includes a power regulator comprising an input for a setpoint power signal and an output for power control signals for the wind turbines the method comprising:
- carrying out feed-forward control at the power regulator by:
- generating a measure of the setpoint power, multiplying the measure by a signal output at the output of the power regulator, and transmitting the result of the multiplication to the wind turbines.
