| Abstract | Although a classic diesel genset may reach 35% efficiency at nominal load, it has very poor efficiency at low load conditions. Still, these conditions often occur in real world applications when combining gensets with variable autonomous loads. Previously, the authors built a hybrid genset prototype achieving fuel consumption reductions of over 30%. As an alternative to this hybrid genset, this paper reports on a variable speed genset prototype. To demonstrate a higher fuel efficiency, a prototype 50 kVA variable speed genset has been built using readily available industrial products. A diesel internal combustion engine supplies power to a PM synchronous generator to produce variable voltage, variable frequency AC. Using a four-quadrant variable-frequency drive and transformer this electrical energy is converted to produce an autonomous 4-wire 50 Hz 3×400 V grid. Operation principle, prototype implementation, first load tests (speed response and power quality) and possible improvements are discussed 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.
