| Abstract | Hybrid line commutation converter-voltage-source converter high-voltage direct current transmission (LCC-VSC-HVDC) power transmission has unique technical advantages, but its overvoltage study is not sufficient at present. In this study, the typical overvoltage phenomenon of hybrid LCC-VSC-HVDC power transmission is analysed and verified by power systems computer-aided design/electro-magnetic transient design and control simulation. On the one hand, overvoltage mechanism of modular multilevel converter module caused by single-phase grounding fault at the valve side of VSC transformer is analysed, and arresters are configured for the protection of the valve. On the other hand, the stress of the arresters at the LCC side is analysed. Installing current reversing protection on the VSC side is proposed. The research of this study provides the recommended arresters configuration in the converter station of hybrid LCC-VSC-HVDC power transmission system. |

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.
