Abstract

A wind farm includes a plurality of wind energy installations which generate electrical energy to be output to a power supply system and a wind farm master for controlling the wind energy installations. Each wind energy installation includes a generator which is driven by a rotor, and the wind farm master includes a power control device having a plurality of loops. This plurality of loops includes a fast loop that includes a controller which acts on a first group of the wind energy installations and a slow loop that includes a controller which acts on a second group of the wind energy installations, the fast controller having a substantially higher dynamic than the slow controller.
