| Abstract | This paper proposes a LCL DC hub concept which plays the role of DC substation in a DC grid. The hub is capable of connecting multiple DC transmission lines with different DC voltages. Each DC transmission line can be added to or isolated from the hub without affecting the operation of the other DC transmission lines. The hub is based on multiple AC/DC IGBT-based converters and an internal passive LCL circuit without internal AC transformers. The LCL circuit is designed to interconnect multiple AC/DC bridges with different DC voltages and achieving minimal reactive power circulation at each converter bridge. Each AC/DC bridge controls its active power independently. The designed hub has the ability to ride through the DC faults by keeping the fault current within the order of its rated value. Detailed PSCAD/EMTDC simulations of a 7-port tests system are presented to validate the proposed topology. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
