Before the UPQC device put into operation, carry out the RTDS test is a very important step, can make the device fully validated MMC structure based on UPQC module as the number of many triggered IGBT, RTDS in order to make rational use of valuable resources, when carrying out the RTDS experiment, we must optimize the design of resource allocation among them, the pulse input scheme is one of the important links. This paper based on describing the topology structure of MMC-UPQC on the first physical controller of RTDS and UPQC structure and demand were sorted and analyzed, and then gives the pulse input scheme two and analyzed, finally, in the RTDS simulation to verify the feasibility of the given.
