ABSTRACT:
Apparatus for providing reactive compensation and positive real power compensation in an ac electric power transmission system, utilizes a solid state inverter 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 is drawn from the transmission line by a rectifier shunt connected to the line.
