Robust Stability And Performance Analysis Of Power Systems : Design of voltage stabilizer and its application to obtain maximum gain with stability limit in power system

The present research project encompasses Robust stability and performance analysis of power systems and it has six definite parts : - The unification of the structural configuration dealing with stability of the closed - loop feedback systems. Stability studies of capacitive loading of synchronous generator of a thermal power station. Regulator excitation dynamics of a synchronous generator. The design of stabilizers and the determination of the largest radius of the hyper-sphere in the parameter space. The determination of the controller stability of a close-loop system by investigating and examining encirclement of the -1+ j0 point by the locus of G (jw) C (jw). D' partition method for stability studies with the range of K have been discussed. The analysis and design of a family of voltage controllers based on numerical convex optimization.
