Abstract
The invention relates to a wind power plant () which consists of a nacelle () arranged on a tower (), a rotor (), a generator (), a power converter () on the generator side, a power converter () on the network side and a transformer (), the two power converters () being electrically connected to each other on the DC voltage side, and the power converter () on the network side being connected on the AC voltage side to a feeding point () of a destination network () by means of the transformer (). Every phase module () of the power converter () on the network side has an upper and lower valve branch (T, T, T; T, T, T) having at least two bipolar subsystems () that are connected in series and the power converter () on the generator side and the power converter () on the network side are interconnected on the DC side by means of a DC cable (). A corresponding wind farm () consists of a plurality of wind power stations () and has a flexible design as compared to known DC concepts, the nacelles () of every wind power station () having a low dead weight.
