Abstract | Real-time simulation of a modular multilevel converter (MMC) plays an important role on the area of large-scale power electronics research. The authors propose a real-time MMC simulation system in a heterogeneous computing platform containing the central processing unit (CPU) and field programmable gate array (FPGA). This system decouples the MMC circuits from the grid based on the alternative circuit equivalent model of the MMC bridge arm. Furthermore, the parallel calculation of the equivalent circuits is achieved when the peripheral circuit is realised on the CPU and the MMC arms are realised on FPGA. In addition, a timing optimisation strategy is discussed to reach the timing target requirement. To validate the MMC simulation system, a case study of a grid with 12 MMC bridges and 640 sub-modules per bridge at 2 μs time step on Xilinx Virtex-7 XC7VX690T FPGA is simulated in real time. The real-time simulation results demonstrate high accuracy of the simulation system in comparison to the offline simulation of the original system in the electromagnetic transient program and our design is competitive to recent published works. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
