| Abstract | In the environment of active distribution network, more distributed control devices are deployed to enhance the system reliability and flexibility. The master station of the distribution automation system is required to transfer real-time topology information to numerous field devices for implementing the distributed operations. To reduce the computational burden of the master station and to make it more autonomous for the distributed agents to utilise the topology information, this study proposes a fully distributed solution to topology processing for the distributed applications. It reduces the grid topology to an undirected graph, divides it into subgraphs and executes a distributed adaptation of graph connectivity algorithm to solve the problem. The algorithm uses the Lagrange multiplier method to optimise the subtask allocation and neighbour-to-neighbour communications to compute the graph connectivity. The configuration technique and the usage are presented to illustrate the distributed approach. The algorithm is applied in a fault location, isolation and service restoration scheme to demonstrate its effectiveness. It is compared with the centralised method to highlight the improved performances. Test results show that the algorithm can recognise changes in real-time topology correctly and has significant advantages. |

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.
