| Abstract | This study proposes a novel rotor position estimation method for wound-rotor synchronous starter/generator (WSSG). At starting stage, WSSG needs a resolver to obtain main generator (MG)'s rotor position. However, the use of resolver increases starting system's complexity, volume, weight and cost. In order to solve this problem, a new kind of MG's rotor position estimation method is proposed, which considers the structure of WSSG as a resolver. This method injects a rotating voltage into MG's stator, detects main exciter's stator currents and subsequently processes the current signals to estimate MG's rotor position. Experiment results show that this method has high estimation accuracy, which are in good agreement with the theoretical analyses and simulation results. Compared to the traditional saliency tracking rotor position estimation method, this method does not rely on WSSG's parameters (including MG's saliency), and the signal processing procedures are more simple. |

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.
