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;
a frequency sensor circuit coupled to receive the frequency of the electrical network;
a control circuit coupled to the wind power installation and receiving an input from the frequency sensor circuit, the control circuit being configured such that 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 threshold amount.
