The present invention concerns a method of operating a wind park having a plurality of wind power installations. A wind power installation includes an electrical energy storage means associated with the wind power installation to store electrical energy which is consumed for starting up the wind power installation after stoppage and consumed for emergency shutdown of the wind power installation. In some embodiments, the wind power installation includes a control system to control taking of energy from the electrical energy storage means for an emergency ...

1. A wind power installation, comprising: an electrical energy storage means associated with the wind power installation storing electrical energy which is consumed for starting up the wind power installation after stoppage and consumed for a controlled shutdown of the wind power installation and controlled shutdown of a second wind power installation; anda control system to control energy consumed during controlled shutdown of the wind power installation such that a sufficient shutdown reserve is maintained in the electrical energy storage means for starting up the wind power installation, said control system rotating the wind power installation into a first azimuth orientation different from a second azimuth orientation of the second wind power installation during controlled shutdown. 2. A wind power installation according to claim 1 wherein the electrical energy storage means is a battery, accumulator, or capacitor. 3. A wind power installation according to claim 1 wherein control of the first azimuth orientation includes rotation of the wind power installation into a predetermined direction based on a prediction of future wind direction when a calm period comes to a conclusion. 4. A wind power installation according to claim 3 wherein the prediction of future wind direction is based on a location of the wind power installation within a wind park relative to other wind power installations within the wind park. 5. A wind power installation according to claim 4 wherein the prediction of future wind direction based on the location of the wind power installation within the wind park is associated with a main compass point (North, East, South, or West) or a pair of compass points. 6. A method to control a wind power installation, comprising: storing electrical energy in an electrical energy storage means associated with the wind power installation;consuming electrical energy from the electrical energy storage means to start up the wind power installation after stoppage;providing electrical energy produced by the wind power installation to rotate a second wind power installation that is not producing electrical energy, the rotation placing the second wind power installation into a second determined azimuth orientation;rotating the wind power installation into a determined azimuth orientation during a controlled shutdown procedure, wherein the azimuth orientation of the wind power installation during the controlled shutdown procedure is opposite to the second determined azimuth orientation; andcontrolling consumption of the electrical energy from the electrical energy storage means during the controlled shutdown procedure such that a sufficient electrical energy reserve is maintained in the electrical energy storage means to start up the wind power installation after stoppage. 7. A method to control a wind power installation according to claim 6 wherein storing the electrical energy in the electrical energy storage means includes storing electrical energy in a battery, an accumulator, or a capacitor. 8. A method to control a wind power installation according to claim 6 wherein rotating the wind power installation into the determined azimuth orientation includes rotating the wind power installation based on a prediction of future wind direction when a calm period comes to a conclusion. 9. A method to control a wind power installation according to claim 8 wherein the prediction of future wind direction is based on a location of the wind power installation within a wind park relative to at least one other wind power installation located within the wind park. 10. A method to control a wind power installation according to claim 8 wherein the azimuth orientation of the wind power installation and the second determined azimuth orientation are based on a determined main wind direction. 11. A control system for a wind park having a plurality of wind power installations, comprising: an electrical energy storage means associated with the wind park to store electrical energy which is consumed for starting up a stopped wind power installation and consumed for a controlled shutdown of a wind power installation to be stopped; anda control system to control energy consumed during the controlled shutdown of the wind power installation to be stopped such that a sufficient electrical energy reserve is maintained in the electrical energy storage means to start up the stopped wind power installation, said control system controlling a first azimuth orientation of the wind power installation to be stopped during the controlled shutdown, wherein a first azimuth orientation of a first wind installation of the wind park is different from to a second azimuth orientation of a second wind installation of the wind park during the controlled shutdown. 12. A control system for a wind park having a plurality of wind power installations according to claim 11 wherein a first azimuth orientation of a first wind installation of the wind park is same as a third azimuth orientation of a third wind installation of the wind park during the controlled shutdown. 13. A control system for a wind park having a plurality of wind power installations according to claim 11 wherein the azimuth orientation of the wind power installation to be stopped during the controlled shutdown is based on a prediction of future wind direction when a calm period comes to a conclusion. 14. A control system for a wind park having a plurality of wind power installations according to claim 11 wherein the azimuth orientation of the wind power installation to be stopped during the controlled shutdown is based on a wind direction that occurred after a past calm period came to a conclusion. 15. A control system for a wind park having a plurality of wind power installations according to claim 11 wherein the azimuth orientation of each wind power installation to be stopped is determined based on a location of the wind power installation within the wind park relative to other wind power installations within the wind park.
