WIND PARK WITH VOLTAGE REGULATION OF THE WIND ENERGY SYSTEMS AND OPERATING METHOD

摘要

The invention relates to a wind park and a method for operating a wind park having at least two wind energy systems (1), each comprising a generator (15) having a converter (17) for generating electrical energy and a control system (2), a park master (8) that is designed for active and idle power control and that transmits a control signal for idle power via a communications network (7) to the wind energy systems (1), and a connection network (3) that connects the wind energy systems (1) to one another, wherein the wind energy system (1) comprises an idle power regulator, at the input of which an idle power target value is stored. The invention proposes that, in addition to the idle power regulator, a supplementary regulator be disposed on the wind energy systems, at the input of which a signal for a target voltage is stored and that emits control signals for the converter (17) in order to change the generated idle power so as to regulate the voltage output by the wind energy systems (1).
