Abstract | In this paper, a new approach is proposed for the transient stability control of a single-machine infinite-bus power system. The proposed method is based on the concept of linear parameter varying (LPV) model and linear matrix inequality (LMI) based gain-scheduling control. It is well-known that when the disturbances are large, the nonlinearity inherent in the power system can no longer be ignored and the performance of closed-loop system designed based on linear approximation degrades severely in such case. Here, we propose a control method which handles the nonlinear model directly and is able to assign the convergence rate. First, we show that the nonlinear model can be transformed into an LPV system with the rotor angle as the time-varying parameter. Then, a gain-scheduled controller is designed by using the gain-scheduling control method. In particular, the input saturation is taken into consideration in the design. Simulation results verify that the proposed method is effective. |

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.
