| Abstract | Due to the high UHV AC/DC transmission line tower, the working voltage amplitude on the wire is large, causing lightning accidents. The paper first analyses the impact of lightning strike point on lightning overvoltage of 1000 kV UHV transformer substation and determines the research object of lightning intruding wave overvoltage. Second, the influence of the impact grounding resistance of transformer side lightning arrester and transmission line tower on invaded wave is analysed. Finally, the commutation failure of HVDC system was analysed, and the simulation tests were carried out by CIGER standard model in PSCAD and Simulink, valve voltage and valve current waveform can be used as a new basis for judgment. The conclusion shows that the analysis of UHV AC/DC hybrid system commutation failure should start from the DC system to study, and commutation failure directly related to the failure, operating conditions, and other factors. |

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.
