| Abstract | Whole-line quick-action protection utilising single-end electrical parameters has been studied and verified in alternating current and direct current power systems. This study analyses the origin of fault generated high-frequency harmonics based on the properties of boundary elements and power source during the fault, creating the possibility for the distribution network to achieve single-ended protection. Based on the non-loss transmission line model, the differences of transient harmonic characteristics are explained by the comparison of the stabilisation process of the power system with boundary elements and the one without. It is revealed that the source generated specific high-frequency harmonics and energy storage elements generated high-frequency harmonics contribute to single-ended protection criterion during the fault. As the protection scheme only relying on the source generated specific harmonics is hard to take effect for all segments of the distribution network, the travelling wave generated harmonics ought to be utilised to distinguish between internal and external faults for each segment by adding a proper boundary element in the line. |

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.
