| Abstract | Two techniques based respectively on the transient energy injected by the disturbance into the grid and the tracking damping level of the resulting oscillatory responses are investigated for quickly assessing the post-event vulnerability status of a multi-area power system from a wide-area measurement systems (WAMS) record. The "transient energy" approach using the so-called wide area severity index (WASI) was originally developed to suit a highly reliable dynamic security assessment (DSA) system which is currently being tested in actual operations. The WASI concept is extended here to provide the necessary attributes for ranking the dynamic strength of the grid after an arbitrary contingency, giving the full 10 to 60-s record from an ensemble of strategically located PMUs. It is shown that wide area severity indices over short and long windows time-frame allow for a very effective clustering of dynamic events into various categories of phenomena with embedded type and level of grid vulnerabilities. For comprehensiveness, a tracking modal analysis using the ERA method is also implemented to provide additional insight into the grid signal responses, in terms of the evolving damping level throughout the observation window. The proposed approaches are illustrated on detailed simulations of the Hydro-Quebec grid and confirmed on actual measurements recorded with the existing WAMS |

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.
