Abstract: A power station is provided with a power machine driving an AC generator for feeding an HVDC power transmission plant, comprising a rectifier station in the power station and an inverter station at the other end of an HVDC line connected to the rectifier station. The power machine is controlled from a machine regulator to provide a desired rotational speed, while the converter stations of the HVDC transmission plant are controlled from a converter regulator to maintain a desired transmission magnitude. The machine regulator and the converter regulator are mutually connected and coordinated so that, in the first place, a change in the state of control of the HVDC plant is fed to the input of the machine regulator and, in the next place, a deviation between the state of control of the power machine and the actual number of turns of this machine influences the converter regulator so that the state of control of the converters is temporarily adapted to that of the power machine.
