Abstract

This paper treats the New England ten-machine model system. On the occasion of multi-faulting points, at first by looking over the entire system from each generator-bus, a decentralized system considering all the faulting points is identified. Then the supplementary control input u_a for AVR in each generator is determined under the concept of equilibrium point control. Further the decentralized system for each generator is transformed into a fuzzy one without any approximation, and the stability analysis is carried out to decide the supplementary control input u_g for GOV in each generator by applying the stability theorem for the fuzzy system. Finally the usefulness of nonlinear decentralized control for multi-faulting points is verified numerically
