| Abstract | As the ability of DC circuit breaker is limited, transmission line protection has to identify the fault and inform the DC circuit breaker to cut off fault current as quickly as possible after a fault occurs on the transmission line of modular multilevel converter-based high-voltage direct current (MMC-HVDC) grid, in order to prevent the fault current from exceeding the ability of the DC circuit breaker. MMC-HVDC grid requires the speed of transmission line protection to be extremely fast. Travelling wave protection utilises the fault-induced travelling waves to construct protection criteria. As fault information firstly propagates in the form of travelling waves in the grid after a fault, travelling wave protection can achieve the fastest operation speed in theory, so it is an ideal choice for MMC-HVDC grid. This study analyses the characteristics of fault-induced travelling waves in the MMC-HVDC grid and the results can be the foundation of travelling wave protection of transmission line in MMC-HVDC grid. |

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.
