Abstract

An installation for transmitting electrical power between a first and a second alternating voltage network. A self-commutated converter can be connected to the second alternating voltage network, and is connected to a unidirectional rectifier by way of a direct voltage connection. The unidirectional rectifier can be connected to the first alternating voltage network on the alternating voltage side, and to a wind farm via said first alternating voltage network. The farm has at least one wind turbine feeding electrical power into the first alternating voltage network when wind speeds are greater than a switch-on wind speed. An energy-generating device can be connected to the first alternating voltage network and/or to the at least one wind turbine for providing electrical energy. The energy-generating device converts a renewable primary energy from its surroundings when wind speeds are lower than the switch-on wind speed for the wind turbine.
