<p>Apparatus (9) for providing reactive compensation and positive real power compensation in an ac electric power transmission system (1), utilizes a solid state inverter (11) to inject a series compensation voltage into the transmission line at a controllable magnitude and a controllable phase angle between + or -90 electrical degrees relative to transmission line current. The positive real power needed by the inverter (11) is drawn from the transmission line (3) by a rectifier (19) shunt connected to the line (3).</p> |
