| Abstract | In the extra-high voltage long transmission line, the non-allowed increasing of power voltage and the corresponding transient oscillation over-voltage are often occurred. The continued burning of the secondary arc usually keeps quite a long time for the high voltage level, long line and large capacity. There must lead to the failure of the re-closing if the secondary arc is not extinguished promptly, which will affect the security and stability of the system. In this paper, the dynamic induced over-voltage model as well as the dynamic secondary arc model in single-phase asymmetric breaking is established based on the distribution parameters of EHV long-line. A novel kind of high-controlled shunt reactor with a small reactor in the neutral is adopted to suppress the transient oscillation over-voltage and the secondary arc. Since the neutral point small reactor is constrained by the positive-sequence and zero-sequence capacitance of the line and the shunt reactor as well. The coordinate control of the neutral controllable small reactor achieves the dynamic change in accordance with the high-controlled shunt reactor which can realize the compensation of the phase capacitor so as to suppress the induced over-voltage and the secondary arc effectively. |

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.
