Abstract
A wind power facility having a plurality of wind power installations, the wind power installations connected to a current voltage network into which the electrical current generated is fed or delivered that, independent of the currently prevailing amount of wind and the active power that is thus available from the wind power installation, a constant apparent power is always delivered into the network. A device for regulating the power to be delivered to a current voltage network is provided so that the regulation is so adjusted to have a constant apparent power always fed to the network.

-
configuring the at least one wind-powered generator to generate active power in response to wind;
rectifying the active power from the at least one wind-powered generator;
converting the rectified power;
supplying reactive power; and
regulating the active power and the reactive power to output a constant apparent power to the network. - View Dependent Claims (11, 12, 13)

14. A device for regulating power generated from a wind power installation for delivery to a network, the device comprising:
-
a rectifier coupled to the wind power installation to receive power generated in response to wind and to output dc voltage;
a frequency converter coupled to the rectifier and configured to receive the dc voltage from the rectifier and to convert the dc voltage into an ac voltage that is output to the network; and
a control device coupled to the output of the frequency converter and having an output coupled to a control input of the frequency converter, the control device configured to regulate the frequency converter to output constant apparent power to the network that comprises active power from the dc voltage at the rectifier output with reactive power from a reactive power supply in accordance with the following formula;
S={square root}{square root over (P2+Q2)} where S is the magnitude of the apparent power;
P is the magnitude of the active power, and Q is the magnitude of the reactive power. - View Dependent Claims (15, 16)
