Abstract | Distributed generation systems are acquiring day by day bigger relevance regarding the conventional ones due to the energy requirements and to the use of sources of ecological and renewable energy. Regarding the energies, one of the most developed is the wind energy, which in many cases uses generating machines of the asynchronous type with multiple excitation feeding. The study was carried out on an induction generator multiply excited, associated to a machine-transformer, to which the system or network was out-of-phase reconnected. This situation is presented when a portion of the system remain working as an island, after a fault has taken place, being quickly reconnected the region. From the test series carried out, it can be concluded that in case of a full out-of-phase connection of an induction generator, the obtained current values are approximately two times the ones obtained in case of terminals direct short-circuit. The behavior of the current varies according to if the out-of-phase connection takes place lightly before the opposition or after it. In the first case the balance position is reached without oscillating, on the other hand in the second situation a complete oscillation cycle takes place. |

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.
