Abstract:
A method of operating a rotor-blade pitch controlling drive of a wind turbine comprising supplying electrical energy to an electrical working load by a primary electrical energy supply, charging an electrical energy storage device by means of a charger, supplying electrical energy to the electrical working load by the electrical energy storage device if the primary electrical supply fails, and temporally disconnecting the electrical energy storage device from the charger in successive intervals, while applying an electric test load to the electrical energy storage device and observing the electrical discharge of the electrical energy storage device.
