Patent ID: 7638893

Claim:
A method of operating a wind park comprising: a plurality of wind power installations, wherein the wind park is connected to an electrical power supply network into which the electrical power produced by the wind park is fed and at least one of the wind power installations of the wind park has a control input, by means of which the electrical power of the wind park installation can be set in a range of between 0 and 100% of the respective power to be made available, and that there is provided a data processing apparatus which is connected to the control input and by means of which the setting value is set in the range of between 0 and 100%, depending on how great is the power that the overall wind park provides at its output for feeding into the energy network and wherein the operator of the electrical supply network to which the wind park is connected can adjust the power delivered by the wind park by way of the control input, such that the delivered electrical power of the wind park is reduced when the network frequency in the electrical power supply network exceeds or falls below a given value and the electrical voltage in the electrical power supply network exceeds or falls below a given value and that the phase angle φ of the phase position of the current which is fed in is changed in dependence on the electrical network voltage.
