Integrated Series Compensation Devices Implementation in a Power Converter Based Transmission Line Emulator

A power converter based transmission line emulator has been developed for the hardware test-bed (HTB) platform, which emulates power systems by mimicking the system components with universal three-phase voltage source converters. In power grids, transmission line series compensation devices are utilized to enhance the power delivery capability and controllability by regulating the equivalent impedance of a transmission line. This paper proposes a method of mimicking variable capacitors and inductors to combine the series compensation device emulation into the transmission line emulator so that various power system scenarios can be studied. Simulation and experiment results verify the effectiveness of the transmission line emulation with integrated series compensation devices.
