| Abstract | This paper presents a study of wide area agents based on communication for primary and backup coordinated protection. Agents are used to give each protection component control capacity as well as the ability to communicate with other agents. We feel that this method naturally points towards a new philosophy for primary and backup protection. Simulations are used to illustrate concepts, using a simulation engine named EPOCHS that combines the EMTDC/PSCAD power simulator with the NS2 network communications simulator. Results illustrate the improved performance of our protection scheme. In this new protection system, agents were embedded in each of the conventional protection components to construct an IED relay (intelligent electronic device). The agent searches for relevant information by communicating with other agents. Agent communications can take place at the same substation or at remote substations. This information can be used to detect primary and remote faults, relay misoperation, breaker failures, and to compensate such problems with much better performance than that can be done in traditional schemes. Preliminary results give us hope that the proposed protection scheme may be able to contribute towards the mitigation of wide-area disturbances and the power blackouts that frequently follow them. |

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.
