Method and windfarm control stage for controlling a windfarm

A windfarm control stage for controlling a windfarm having a plurality of wind power installations and feeding into an electrical supply network at a network connection point, the windfarm control stage comprising:

• a control error input configured to receive at least one control error,
• a manipulated variable output configured to output at least one manipulated variable for transmission to the plurality of wind power installations,
• at least one controller configured to generate the at least one manipulated variable based on the at least one control error,
• a state input for recording, as a form state, a state of at least one of:
• the windfarm, the plurality of wind power installations of the windfarm or an ambient condition, and
• a controller setting device for altering or predefining at least one property of the at least one controller based on the recorded form state.

A windfarm control device configured to control a windfarm having a plurality of wind power installations and feed into an electrical supply network at a network connection point, the windfarm control device comprising:

• a measurement input for recording at least one measurement signal,
• a setpoint value device for setting at least one setpoint value,
• a windfarm control stage for generating at least one manipulated value for the wind power installations,
• a state input for recording, as form state, a state of at least one of the windfarm, the plurality of wind power installations of the windfarm or an ambient condition, and
• a controller setting device for altering or predefining at least one property of the windfarm control stage based on the recorded form state.

A wind power installation, comprising:

• a generator,
• an aerodynamic rotor coupled to the generator, the generator configured to generate electrical power from wind,
• an inverter configured to generate electric current for feeding into an electrical supply network,
• a connection configured to electrically connect the inverter to an internal form network of a windfarm to feed the generated electric current into the electrical supply network at a network connection point, and
• a communication device configured to communicate with a windfarm control stage or a windfarm control device to receive and implement manipulated variables from the windfarm control stage or the windfarm control device,
• wherein the wind power installation is configured to transmit states of the wind power installation via the communication device to the windfarm control stage or the windfarm control device to enable the windfarm control stage or the windfarm control device to alter at least one property of a controller of the windfarm control module or of the windfarm control device based on the transmitted states.
