The development of an advanced series compensator based on a single voltage source inverter

This paper describes the progress of a project to develop a working laboratory prototype of an advanced transmission line series compensator, based on a single voltage source inverter. The paper describes the development of a control scheme suitable for practical implementation of the inverter based compensator idea and presents practical results to confirm the predicted capabilities of this unified power flow controller. Practical results from a working laboratory prototype demonstrate the ability of the compensator to provide a rapidly controllable magnitude of compensating reactance in the transmission line
