Abstract | Doubly-fed Induction Generator (DFIG) is a kind of variable-speed constant-frequency (VSCF) wind generator (WG) which can output reactive power when not working in the constant power factor mode and be used as a reactive power supply for wind farm. In this paper, an optimal control strategy for reactive power in wind farms consisting of DFIG is proposed by combining the reactive power compensation ability of both DFIG and reactive power compensation device (RPCD). The control target is minimum power loss and optimal power flow (OPF) of wind farm. First, the reactive power characteristic of DFIG is detailed analyzed. Then the control strategy which includes three modules is presented based on the “Fix-place and Quantitative” thought, and the modules of which are Wind Farm Data Process Module (WFDPM), Wind Farm Data Acquisition Module (WFDAM) and Wind Farm Control Module (WFCM). As the core part of the strategy, WFDPM applies Sensitivity Analysis (SA) and improved genetic algorithm (IGA) to optimize the control strategy. At last, a wind farm consisting of twenty DFIGs of 1.5MW is built in DIgSILENT/PowerFactory, and the results data show that the optimal reactive power control strategy proposed in this paper can effectively achieve the minimum power loss and OPF. |

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.
