A control device for rectifier stations in a high-voltage DC transmission system has a rectifier drive unit and an inverter drive unit for driving power rectifier stations that are working either as a rectifier or as an inverter. The trigger angles for the rectifier or for the inverter can be adjusted and regulated by way of the rectifier drive unit and the inverter drive unit respectively. A delay element is placed between the rectifier drive unit and the inverter drive unit with which the start time for regulating the trigger angle for the inverter relative to the start time for regulating the trigger angle for the rectifier can be delayed by a predetermined delay time. Because of less mutual interaction of the trigger angle control processes, a relatively faster transition from an initial operating state into a new stationary state results. |
