US 11,108,238 B2 · Method for operating a wind farm

Abstract

Provided is a method for operating a wind power installation or a wind farm with a number of wind power installations for exchanging electrical power between the wind farm and an electrical supply grid. Each wind power installation has one or more feeding-in devices. The wind power installation or the wind farm is connected to the electrical supply grid by a grid connection point. The power is exchanged by way of the grid connection point. One or more of the feeding-in devices operate as voltage-influencing units and one or more of the feeding-in devices operate as current-influencing units. The voltage-influencing units and the current-influencing units also operate in a voltage-influencing and current-influencing manner during undisturbed operation of the electrical supply grid.
