Title: METHOD FOR THE COMPENSATION OF CURRENTS TO BE FED IN FROM A WIND PARK
Abstract:
The invention relates to a wind park for feeding a total electric current into an electric supply network at a network connection point, wherein the wind park has at least one wind energy plant which is constructed as a compensation wind energy plant, and has an active compensation unit in order to generate a compensatory partial current having a modulated-on compensation component, wherein the compensation component is modulated on by the active compensation unit, and has at least one further wind energy plant which, as a compensation-free wind energy plant, is configured to generate a non-compensated partial current without modulated-on compensation component, wherein the compensatory partial current or the compensatory partial currents and the non-compensatory partial current or the non-compensatory partial currents are superimposed onto the total electric current to be fed in in a park network that connects the wind energy plants, and the compensatory partial current or the compensatory partial currents are generated in such a way that the total currents to be fed in at a reference point in the park network, in a section between park network and network connection point or in the electric supply network, influences a reference current that occurs or a reference voltage that occurs, in order to achieve a predefined current form for this reference current or a predefined voltage form for this reference voltage.
