Abstract：MMC type back-to-back HVDC system has received wide attention in the world. Based on Nan'ao ±160kV, 200MW HVDC demonstration project, developed the high power, MMC type back-to-back HVDCprototype.First introduce the basic structure of MMC valve that using IEGT component, and then illustrates the system structure of the test prototype, the main system parameters, main role of transformer, valve reactor and charge resistance. The configurations of control and protection system are introduced. Simulation analysis the test prototype, study on the transient voltage and current waveform when HVDC occur fault, and the fault include monopole grounding fault at DC side, DC side bipolar short-circuit fault and transformer secondary side fault, to validate the correctness of theoretical analysis and digital simulation of HVDC system, laid the theoretical foundation for the engineering application..
