| Abstract | Following a major disturbance, each synchronous generator connected to a power system experiences a net difference between its mechanical power input and electrical power output which leads to instability of the system. This paper deals with the investigations regarding the transient stability enhancement of a synchronous generator making use of a fuzzy logic controlled braking resistor scheme. Following a fault, variable rotor speed of the generator is measured and the firing-angle for the thyristor switch is determined from the crispy output of the fuzzy controller. By controlling the firing-angle, braking resistor can control the accelerating power in generator and thus improves the transient stability. The effectiveness of the proposed controller has been demonstrated by considering balanced (3LG: three-phase-to-ground) faults near the generator. Simulation results clearly indicate that the proposed fuzzy control strategy provides a simple and effective method of transient stability enhancement of synchronous generator. |

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.
