Abstract
A method for the transmission of DC current via a DC network between at least one rectifier station and several inverter stations wherein reference inputs are formed on the basis of a fixed predetermined current-voltage characteristic and a fixed predetermined voltage-current characteristic matched to the aforesaid current-voltage characteristic for the voltage controller of the rectifier of the rectifier station and for the current controller of each inverter station, respectively. The formed reference input for each current controller is released to that current controller when the maximum value of the formed reference input exceeds a value determined for the reference input corresponding to the power demand associated with the inverter station which includes that current controller. When the maximum value of the formed reference input is less than the latter determined value, such value is released as the reference input to the current controller.
