Resumo


A avaliação da estabilidade a pequenas perturbações, em sistemas elétricos de potência de grande porte, é realizada pelo cálculo de autovalores dominantes de matrizes esparsas. Este trabalho apresenta melhorias significativas no algoritino paralelo, para o cálculo de autovalores dominantes, reportado em [1]. Os autovalores são calculados pelo algoritmo de Iterações Simultâneas, implementado num computador paralelo iPSC/860 da Intel. Resultados são apresentados para um modelo prático de sistema de potência, mostrando grandes “speed-ups” obtidos em computação paralela.
