1. A method of operating a wind park having at least one wind power installation comprising an electrical generator driven by a rotor of the wind power installation and operable to deliver electrical power to an electrical power supply network, and a control device for controlling the voltage and/or the current of the electrical power delivered to the electrical network, comprising:

  • setting the electrical power delivered by the wind park to be in a range of between 0% and 100% of the electrical power capability by a control input to the control device;

    adjusting the delivered electrical power by an operator of the electrical power supply network to which the wind park is connected via the control input;

    measuring a value of a network voltage at least at one location in the electrical power supply network;

    feeding the value of the measured network voltage to the control device;

    reducing the delivered electrical power of the wind park when the measured voltage exceeds a given voltage; and

    changing a phase angle φ

    in dependence on the value of the measured network voltage, wherein the phase angle φ

    determines the phase position between the current and the voltage which is delivered to the electrical power supply network.
