Title: INSTALLATION FOR TRANSMITTING ELECTRICAL POWER COMPRISING A FILTER UNIT
Abstract:
The invention relates to an installation (1) for transmitting electrical power comprising a unidirectional rectifier (2) which can be connected at the AC voltage end to a first AC voltage supply system (3), a self-controlled converter (6) which can be connected at the AC voltage end to a second AC voltage supply system (9), and also comprising a DC voltage connection (5) which connects the rectifier and the converter to one another at the DC voltage end. The invention is distinguished by a filter unit (14) which is connected at the DC voltage end to the converter and which forms a current path to a neutral point (15, 34) of the second AC voltage supply system, wherein the current path has a high impedance for a direct current and a low impedance for an alternating current at the fundamental frequency of the second AC voltage supply system. The invention further relates to a modular multistage converter (6) comprising the filter unit (14).
