FIELD: electricity.
SUBSTANCE: control device for transformer substations (5, 6) in high-voltage installation (1) of DC transfer comprises a unit (12) of rectifier control and a unit (13) of inverter control to control transformer substations that operate accordingly as a rectifier (5) and an inverter (6). Firing angles of accordingly the rectifier (5) and the inverter (6) are set and adjusted with the help of the units (12, 13). Between the units (12, 13) there is a delay link (20), with the help of which the start-up torque for adjustment of the inverter (6) firing angle is delayed relative to the start-up torque for adjustment of the rectifier (5) firing angle for the specified delay time (Δt).
EFFECT: provision of relatively quick transition from initial operating condition into new established operating condition.
