Abstract
Provided is a method for operating a wind power installation including starting a discharge operation of an electrical store of an uninterruptible power supply, in particular at a specific time; performing the discharge operation until the electrical store has a predetermined discharge voltage; detecting a discharge current of the electrical store during the discharge operation; and determining a capacity of the electrical store from the detected discharge current.
Claims20
A method for operating a wind power installation, comprising:
- starting a discharge operation of an electrical store of an uninterruptible power supply;
- performing the discharge operation until the electrical store has a predetermined discharge voltage;
- detecting a discharge current of the electrical store during the discharge operation;
