ABSTRACT:
In a convertor station for connecting a high voltage DC line and an AC network, the station is composed of a plurality of static convertors parallel connected on the DC and AC sides and a regulator for setting a predetermined transmission magnitude between the DC and AC sides of the station. Each static convertor has a separate regulating circuit connected to the regulator for the station. Limiting circuits are provided in parallel with each other and each connected to one of the regulating circuits, the limiting circuits being connected to the output side of the regulator. The output sides of the limiting circuits are each connected to one of the regulating circuits, and are all of them connected to a common summation device which feeds back the summation signal from the limiting circuits to the input side of the regulator.
