Abstract
Abstract The invention concerns an electrical energy transmission installation for the transmission of electrical energy from a generator producing a first AC voltage by way of a transmission line into an electrical AC voltage network, comprising a circuit arrangement which converts the first AC voltage produced by the generator into a first DC voltage and feeds it into the transmission line, and a first inverter which is connected to the output of the transmission line and converts the first DC voltage into a second AC voltage and feeds it into the AC voltage network. The particularity of the invention is that the circuit arrangement has a current converter circuit which converts the first AC voltage produced by the generator into a third AC voltage, a first transformer which converts the third AC voltage into a fourth AC voltage, and a first rectifier which converts the fourth AC voltage into the first DC voltage.
