<p>Method and device for control of a series-compensated converter station comprising control equipment (CE2) which generates an ordered value (AOL) of a control angle ( alpha ) in dependence on a limiting signal (AMAXL), capable of being influenced. A calculating value (AMARG) of a control angle is calculated continuously according to a predetermined relationship (M0, M1, M2, M3) which at least approximately resembles a relationship according to which, at a commutating margin ( gamma m) equal to a preselected value ( gamma p), said control angle being a function (F0) of a current (Id2) and a voltage (Un2) in the converter station and the limiting signal being formed in dependence on the calculating value. <IMAGE></p> |
