Abstract | In the modular multilevel converter (MMC)-based multi-terminal high-voltage direct current (HVDC) system, the fault current rises rapidly due to sub-module capacitors discharging when a DC-side short-circuit fault occurs, which makes the MMC easily blocked for self-protection. To avoid the blocking of the converter station and lower the DC fault current, this study proposes a novel fault current limiter (FCL) for MMC-based multi-terminal DC grids. First, the fault current limiting circuit, which consists of resistance, capacitance and power electronic components is designed. Then, the operation principle of the FCL is analysed in detail. Afterwards, the startup criterion is constructed, and the selection method of the key parameters in the fault current limiting circuit is also introduced in order to prevent the converter station from blocking in the case of DC short-circuit fault. Finally, a simulation model was built using PSCAD/EMTDC software, and extensive simulation results verified the effectiveness of the proposed FCL. |

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.
