Abstract

A wind park system is disclosed. Briefly described, one embodiment comprises at least one wind power installation having a generator for the delivery of electrical power to an electrical network, characterized in that the power delivered to the network by the wind park is regulated or adjusted in dependence on the network frequency of the electrical network.

Claims

1. A wind park, comprising:

at least one wind power installation having a generator to deliver electrical power to an electrical network, the wind power installation being adapted to vary the amount of the electrical power that is delivered to the electrical network in dependence on a network frequency of the electrical network, wherein the electrical power which is delivered by the wind park and fed into the electrical network is reduced when the network frequency of the electrical network deviates from a defined value by a first threshold amount and further, wherein the wind power installation does not deliver any electrical power to the electrical network if the network frequency exceeds or falls below the defined value by a second threshold amount.

2. The wind park according to claim 1 wherein the second threshold is 2%.
