摘要
FIELD: electricity.;SUBSTANCE: control unit (17) for a thyristor-controlled series capacitor connected to a electric power transmission line (12) comprises a control unit integrating a thyristor start control (18) and a generator of required voltage of the capacitor passing through zero depending on line current and voltage of the capacitor in response on a command signal, and a command control (19) which is used to generate the command signal for the thyristor start control, and accommodates a command damping control (24) comprising a damping unit at least on one discrete frequency.;EFFECT: reduced subsynchronous resonances which can cause a damage of mechanical or electrical equipment, in the offered device due to protection units, positive damping from an electric supply circuit does not depend on positive damping of a mechanical system.;9 cl, 5 dwg
