Abstract: A method of operating a wind power installation is disclosed. In the method, a network frequency of an electrical network is measured and an amount of power delivered to the electrical network is controlled by at least maintaining the amount of power delivered without changing the power when the network frequency is between a rated frequency for the electrical network and a deadband frequency. Further, the amount of power is increased by a first amount when the network frequency is between the deadband frequency and a control-band frequency, whereby the first amount is proportional to a difference between the network frequency and the deadband frequency. In addition, the amount of power delivered is increased by a second amount when the network frequency is less than the control-band frequency. The second amount is a preset amount of power that is determined based on a difference between the control-band and deadband frequencies.
