Construção de nomogramas para operação de SEPs considerando restrições de estabilidade transitória

Abstract

This work presents a computacional tool capable of draw transient stability constrained dynamic security regions. First, a conceptual approach about stability of electric power systems (EPS) is presented. Besides, it presents a mathematic modeling necessary for transient stability analysis and an algoritm developed to map dinamic security regions. With this algoritm, developed in MATLAB R software, comparisons between the estimated critical time obtained and the literature results are made for two power systems: IEEE 9 buses and south-southeast brazilian reduced power systems. The results presents the dinamic security region for conditions with different levels of detailment. The computacional tool developed presents feasible results for application in power system operation.
