| Abstract | Wind turbines should have fault ride through capability, and also it can provide damping for the power grid by improving the control strategy. However, the currently corresponding control strategy is designed independent for the fault voltage through control and damping control. If the fault ride through control and damping control of a converter is uncoordinated under the grid fault, the output of the two control branches can be superimposed, which will affect the output power dynamic performance of doubly fed induction generator (DFIG) after clearing the fault. At the same time the overcurrent and other issues may occur in serious cases, and even lead to DFIG trip off. Based on the dynamic process analysis of DFIG after clearing the fault, an additional damping controller in the rotor side converter control of DFIG is designed, which damps the system low-frequency oscillation by modulating the rotor active current component. A coordination damping control strategy of DFIG based on a fault ride through control and damping control is proposed for damping the power oscillation after clearing the fault, the correctness of the proposed control method has been verified through time-domain simulation. |

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.
