| Abstract | Summary form only given. Although digital control centers have become more sophisticated since their revolutionary introduction in the 60s, their application and use have varied according to the individual tastes rather than a coordinated agreement on the functionality to ensure reliable operation. This was dramatically illustrated during the minutes before the August 14, 2003 blackout when the operators at the first energy control center were blissfully ignorant that not only were their own system in jeopardy but was about to shut out the lights for 50 million people. Moreover, after the blackout the post-mortem was made particularly difficult when it became clear that the data preserved at the many control centers within the blackout area could not be easily matched to determine what happened. In fact, even the task of aligning the data in time sequence was manual and arduous (and not very accurate). Much has been said about making reliability standards mandatory, and, by and large, reliability standards already exist for planning and operating the power grid. Unfortunately, these standards do not cover monitoring and control in any detail (with the notable exception of frequency control), perhaps because of the mistaken assumption that only redundancies in transmission and generation provides reliability. However, closer monitoring and better control of the grid also provides reliability because it enables the operation of the grid even closer to its limits. |

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.
