| Abstract | This paper proposes a novel configuration for wind energy applications by using a cascaded brushless doubly fed induction generator (CBDFIG) controlled by direct torque control (DTC), which eliminates the slip rings and brushes associated with the conventional DFIG and features quick response. Due to the increased complexity of CBDFIG model, prior vector control for CBDFIG is complicated and relies much on the machine parameters and controller tuning. Furthermore, so far the literature regarding CBDFIG did not address the issue of grid synchronization, which is important for reducing the impacts on both grid and CBDFIG and useful for re-closing after fault is cleared. This paper investigates the analysis and design of DTC of CBDFIG for both grid synchronization and grid connected operations without changing the switching table. The influence of additional rotor circuit is investigated and it is found that this influence is small and can be neglected. The DTC developed in this paper is very simple and achieves excellent dynamic response and steady state performance. Simulation results are presented to validate the effectiveness of the developed DTC for CBDFIG. |

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.
