| Abstract | The high voltage (HV) and Extra High Voltage (EHV) lines could be reestablished by auto-reclosing operation of transmission switches automatically after a certain time from the first tripping during fault. Successful reclosing is carried out considering a dead time which is usually chosen based on the quenching time of possible secondary arc. However, this is not enough to guarantee the transient and dynamic stability of the system. The reclosing instant is the key factor in acceleration or deceleration of power oscillations, and should be determined carefully to ensure the stability of the system. Power oscillations can be mitigated by adaptive selection of the dead time. In this paper, a new method for dead time calculation is proposed in order to mitigate power oscillations effectively. The proposed method is also capable of utilizing in on-line identification because of low amount of calculation required. In this algorithm, single machine infinite bus equivalent (SIME) method is used for evaluation of power oscillations. |

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.
