Le filtrage des défauts dans l'analyse de la sécurité dynamique en temps réel des grands réseaux électriques

Abstract : On-line dynamic security analysis is very difficult to realize because of the numerous calculations necessary in just a few minutes. Until now, no methods hâve been able to accomplish this task. In this context, contingency screening is very important because it allows reducing significantly the number of calculations. The scope of this study has been to realize contingency screening with existing transient stability analysis methods. First, the main transient stability analysis methods hâve been studied and tested with four power Systems. Subsequently, the most efficient methods hâve been modified and improved to increase their speed, reliability and accuracy, Following thèse modifications, two new dynamic security analysis methods hâve been designed. The first method allows a quick and accurate détermination of the power System stability. The second method allows the précise CCT calculation within a few simulations. From thèse two methods which hâve complementary characteristics, a multi-level contingency screening method has been proposed. This screening method is reliable, accurate and fast.
