| Abstract | The reactive power characteristics of doubly fed variable speed constant frequency (DFVSCF) wind power generator are important for grid's voltage stability and generator's low voltage ride-though (LVRT) capability. From the equivalent circuit of doubly-fed induction generator (DFIG), the balance equation of reactive power was deduced. Based on the balance equation, this paper first discussed the reactive power conversion relationship between stator and rotor whose frequencies are different, then analyzed the mechanism of DFIG's flexible and strong capacity in reactive power regulation. It further investigated the reactive power characteristics of DFIG under different operation conditions, and summarized the influence of slip rate and stator reactive power on rotor reactive power. At last, simulation research was carried on and the results verified the validity and correctness of analysis and conclusion. |

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.
