| Abstract | Offshore wind turbines are distributed in a wide area where the power is generated usually at low voltage levels of 380∼690 V. To reduce electrical power transmission losses, a low-frequency transformer is placed inside the nacelle of the offshore wind turbine to step-up the voltage up to the voltage levels of 11∼33 kV. The heave weight and large size of the step-up transformer significantly increase the weight and volume of the nacelle. These penalties are critical in offshore applications, where cost of installation and regular maintenance are extremely high. As an alternative approach to achieve a compact and light offshore wind turbine a medium-voltage converter using series connected H-bridge multilevel converter topology is proposed in this paper. The transformer-less approach thus leads to a compact and environmentally friendly design, which can save large amount of installation, running and maintenance costs of offshore wind turbines. This paper mainly focuses on design and simulation of 33 kV offshore wind turbine generating system. |

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.
