| Abstract | Connections of distributed generations (DGs) powered by renewable energy resources on power systems start to show benefits but cause new concerns in system operations such as challenges in feeder protections. This paper proposes a new strategy for network-integrated adaptive protection and control of distribution feeders connected with DGs. The proposed strategy provides intelligent network-enabled protections for DG-connected feeders and overcomes DGs-imposed protection challenges such as increase of fault levels, change of prescribed fault flow paths, mis-coordinated tripping, unintentional islanding operations, non-interruptible fault currents, etc., and nonDG-caused problems such as undetected high-impedance ground faults. This paper presents a new architecture for monitoring/protecting network of multiple (over-hundred) feeder nodes. This architecture consists of four layers: backbone network, area domains, local domains, and cell units. The architecture is fault tolerant and has features from the classical star and ring architectures. The design, implementation, case studies, and field tests validation for the proposed network- integrated adaptive feeder protection are provided. |

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.
