KünyeKesler, M., Ozdemir, E., Kisacikoglu, M. C., & Tolbert, L. M. (2014). Power converter-based three-phase nonlinear load emulator for a hardware testbed system. IEEE Transactions on Power Electronics, 29(11), 5806-5812.
A three-phase nonlinear load emulator using a power electronic converter is presented in this study. The proposed nonlinear load emulator is intended to be used in an ultrawide-area grid transmission network emulator, also called hardware testbed (HTB). The emulator converter is controlled in rectifier mode to act as the real nonlinear three-phase diode rectifier load. This paper presents an accurate controller for the nonlinear load emulator based on a three-phase diode rectifier system to be used in the HTB. This study also demonstrates simulation and experimental results for verification of the proposed controller.
