| Abstract | With the wide application of PMU in power system, the real time prediction and emergency control of power system transient instability using the wide-area measurements has brought wide attention. There are two sub-problems: the postfault rotor-angle trajectory prediction and the real time transient instability detection. There are three categories for the former sub-problem. They are the network reduction based rotor-angle trajectory super-real time simulation, the curve-fitting based trajectory extrapolation and the angle speed prediction and integration methods. The curve-fitting based trajectory extrapolation includes the polynomial function, the auto regression model and the trigonometric function model. There are three types of criteria for the transient instability detection. They are the threshold-type criteria, the differentiation-type criteria and the integration-type criteria. The threshold-type criteria include the rotor angle threshold and the angle speed threshold and the post-fault voltage trajectory based criteria. The differentiation-type criteria include the trajectory concave and convex characteristics based criterion and the instability criterion based on the variation rate of energy function. The integration-type criterion mainly is the EEAC theory based instability criterion. A comprehensive comparison, analysis and reviews of the fundamental properties of these methods are presented in this paper. |

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.
