| Abstract | In order to utilize Doubly Fed Induction Generators (DFIGs) as primary power source of an isolated system, they must be able to regulate the voltage and frequency of the system, as well as ride-through faults. This paper proposes a new control strategy for a DFIG operating in an isolated power system, accomplished by a Dynamic Voltage Restorer (DVR) and a Supercapacitor Energy Storage System (SCESS), in order to ride through symmetrical and asymmetrical faults. During faults, the DFIG continues to operate normally, while the surplus of power is stored in the SCESS. During asymmetrical faults, the DFIG and the DVR are properly controlled in order to feed the non-faulty phases uninterruptedly. When integrated in a power system with conventional synchronous generators, the proposed FRT control strategy improves the FRT capability of a DFIG, while providing frequency and voltage support to the system throughout the fault duration. Thus, the transient stability of the power system is significantly improved. The effectiveness of the proposed control method under different fault conditions is verified by detailed simulation results. |

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.
