Wind turbine or wind park for supplying electric power

摘要

Provided is a method for supplying electric power to an electric supply network at a network connection point using a converter-controlled supply apparatus. The converter-controlled supply apparatus may be a wind farm or a wind turbine. A selection is permitted at least between a current-impressing operating mode and a voltage-impressing operating mode for the purpose of supplying the electric power. Open-loop or closed-loop control to a desired current value is substantially or predominantly performed in the current-impressing operating mode, and open-loop or closed-loop control to a desired voltage value is substantially or predominantly performed in the voltage-impressing operating mode.
