| Abstract | IEC61850 has now been accepted ‘almost unequivocally’ as a preferred standard for substation communications.The extent of utilisation of this standard in a majority of installations around the world is at the ‘station bus’ level. It is foreseen that numerous benefits can be availed if the process values are digitised as close to the source as possible and utilised in a comprehensive automation system. TransGrid carried out an extensive assessment of the substation secondary system design based on the implementation of IEC61850 at the station and process bus level which brought out the business case for full digitisation. The first substation to realise this technology is the Avon 330 kV switching station. At Avon, merging units are installed in outdoor cubicles; digitised signals are then transferred to the substation systems. There has been a special focus on standardisation and re-usable engineering – these are some of the crucial factors to achieve cost reduction. The study describes some of the design principles, estimated cost savings and lessons learnt. The authors envisage that the digital substation technology implemented can bring about substantial cost reduction in green-field as well as brown field builds and paves the way for the efficient integration of asset monitoring systems. |

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.
