Abstract

A wind park and operating method thereof. The wind park includes at least two wind energy systems each comprising a generator and converter for generating electrical energy and a control system, a park master designed for active and idle power control that transmits a control signal for idle power via a communications network to the wind energy systems, and a connection network feeding generated electrical energy into a grid. The wind energy system can include an idle power regulator and a supplementary regulator, the control signals of each of which are linked together. Thus, a combination of idle power and voltage regulation is achieved that combines the advantages of each. Accordingly, the wind park can have high dynamic and stability notwithstanding erratic changes in the grid.
