ABSTRACT:
In a convertor plant for connection between a DC network and an AC network which includes at least one convertor group formed of two convertors with AC terminals for connection to the AC network and DC terminals for connection to the DC network, a reactor is connected on the DC side of one of the convertors and switches are provided for alternatively connecting the DC terminals of the convertor to the DC network in parallel with the other convertor or for connecting the reactor between the DC terminals of the convertor. Preferably the plant includes two or more convertor groups, each of which is provided with a transformer for connection to the AC network, and the transformers have different circuit angles for increasing the resulting pulse number of the plant.
