Abstract

A converter station for the transmission of electrical power includes a converter with a DC connection terminal and an AC connection terminal, and at least one transformer connected to the AC connection terminal. In order to render the converter station as cost-effective as possible, the station is distributed over at least two independent supporting structures.

First claim

1 - 18 . (canceled)

19 . A converter station for transmitting electrical power, the converter station comprising:
a converter having a DC-voltage connection and an AC-voltage connection; at least one transformer connected to said AC-voltage connection of said converter; and at least two support structures erected independently of one another and supporting the converter station distributed over said at least two support structures.

20 . The converter station according to claim 19 , wherein said converter and at least one said transformer are disposed on mutually different support structures.

21 . The converter station according to claim 19 , wherein said support structures are disposed to project from a body of water and at least one of said support structures is a wind-turbine support structure configured and dimensioned to hold a wind turbine.

22 . The converter station according to claim 19 , wherein said converter has a plurality of DC-voltage side series-connected or parallel-connected partial converters, and wherein said partial converters are held at least partially on mutually different said support structures.

23 . The converter station according to claim 22 , wherein said at least one transformer comprises a plurality of partial transformers and each said partial converter is connected on an AC-voltage side to a respective partial transformer.

24 . The converter station according to claim 23 , which comprises a partial encapsulation housing commonly housing said partial converter and said partial transformer.

25 . The converter station according to claim 22 , wherein each partial converter has two DC-voltage terminals and a bypass switch is disposed to bridge said two DC-voltage terminals and to bypass said partial converter.

26 . The converter station according to claim 22 , wherein each said partial converter forms a six-pulse bridge.

27 . The converter station according to claim 22 , wherein each said partial converter forms a twelve-pulse bridge.

28 . The converter station according to claim 19 , which comprises a filter unit connected on an AC-voltage side of said converter.

29 . The converter station according to claim 22 , which comprises a partial smoothing converter connected to a DC-voltage side of each said partial converter.

30 . The converter station according to claim 22 , wherein said partial converters are at least partially partial diode rectifiers with current valves formed by a series circuit composed of diodes or thyristor partial converters with current valves formed by a series circuit composed of thyristors.

31 . The converter station according to claim 19 , wherein said converter is a diode rectifier.

32 . The converter station according to claim 31 , which comprises a partial smoothing inductor connected on a DC-voltage side to said diode rectifier.

33 . The converter station according to claim 19 , which comprises a power supply device for supplying an AC-voltage grid connected to the converter station with electrical power.

34 . The converter station according to claim 33 , wherein said power supply device comprises a partial converter connected in series with said partial diode rectifiers on the DC-voltage side.

35 . The converter station according to claim 19 , wherein each of said at least one transformer is connected to a switchgear assembly.

36 . The converter station according to claim 35 , wherein said switchgear assembly is connectable via an AC-voltage line to a coupling-in component that is connected to a power supply grid on land or an AC-voltage grid at sea.
