Abstract
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.
Claims20
A method for supplying electric power to an electric supply network at a network connection point by a converter-controlled supply apparatus, comprising:
- permitting a selection between at least a current-impressing operating mode and a voltage-impressing operating mode for supplying the electric power;
- performing open-loop or closed-loop control to a desired current value in the current-impressing operating mode;
- performing the open-loop control or the closed-loop control to a desired voltage value in the voltage-impressing operating mode;
- changing an instantaneous operating mode between the current-impressing operating mode and the voltage-impressing operating mode in a plurality of steps or a seamless transition;
- and
- setting a mixed operating mode that combines a current-impressing property and a voltage-impressing property.
A supply apparatus for supplying electric power to an electric supply network at a network connection point, comprising:
- at least one converter or inverter configured to supply the electric power to the electric supply network resulting in operating the supply apparatus in a converter-controlled manner;
- and
- at least one changeover open-loop controller for changing between a current-impressing operating mode and a voltage-impressing operating mode, wherein
- open-loop or closed-loop control is performed to a desired current value in the current-impressing operating mode,
- the open-loop control or the closed-loop control is performed to a desired voltage value in the voltage-impressing operating mode, and
- a mixed operating mode that combines a current-impressing property and a voltage-impressing property is set.
