Abstract
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 shutdown procedure such that a sufficient emergency shutdown reserve is maintained in the electrical energy storage means to start a first wind power installation without consuming energy from a network.
Claims20
A wind power installation, comprising:
- 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 a controlled shutdown of the wind power installation;
- and
- a control system to control energy consumed during the controlled shutdown such that a sufficient shutdown reserve is maintained in the electrical energy storage means for starting up the wind power installation, said control system to control azimuth orientation of the wind power installation during the controlled shutdown.
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;
- rotating the wind power installation into a determined azimuth orientation during a controlled shutdown procedure;
- and
- controlling 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.
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;
- and
- a 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 to control azimuth orientation of the wind power installation to be stopped during the controlled shutdown.
