| Abstract | Vector control of Induction Motor (IM) is usually used in speed regulating system. However, in wind power generation system, speed regulator is not needed. On the contrary, there is only a stator current closed-loop in the traditional wind power generation system. The torque set by the turbine controller is controlled indirectly by closed-loop current control. However, the torque control accuracy is low because of the influence of the parameters. Torque closed-loop control can improve the control accuracy, but the feedback torque needs be observed. In this paper, a real-time stator flux observation method based on minimum order flux observer is proposed, based on which the stator flux and torque are calculated. The proposed stator flux observer avoids the flaws of the traditional pure integral strategy, such as saturation, phase shift, amplitude deviation, and so on. Meanwhile, the proposed stator flux observer is robust to parameters, namely, the preciseness of the observed torque is almost not affected by mutual inductance. Experiments of 130KW IM validate the performance of the proposed method. |

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.
