摘要： 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.

摘要： A commutating circuit for an electronic power converter has a first switching device, by which the electronic power converter can be electrically bridged, and a circuit part for limiting the size of the time-related voltage change of a voltage present on the first switching device. The circuit part limits the time-related voltage variation.

摘要： A system transmits electrical power between a first and a second alternating voltage network. A self-commutated converter can be connected to the second alternating voltage network, the converter being connected to an unregulated rectifier via a direct voltage connection. The unregulated rectifier can be connected to the first alternating voltage network on an alternating voltage side. The system has a network generation device, which can be connected to the first alternating voltage network and is provided for generating an alternating voltage in the first alternating voltage network. The network generation device is configured to exchange reactive power and active power with the first alternating voltage network. Furthermore, a method is provided which stabilizes a network frequency of the first alternating voltage network, in which the network frequency in the first alternating voltage network is regulated by changing a voltage at the direct voltage terminal of the self-commutated converter.
