Abstract (EN): This paper analyses the security of an Electric Power System (EPS) using an efficient contingency filtering and ranking algorithm. The proposed technique is divided in three modules, with different complexity levels. The contingencies are ranked in accordance with severity indices that allow to accurately evaluate the impact of the overloads and voltage limit violations in the power network. The last module also includes indices that can detect voltage instability situations. The computer programs developed by the authors were applied to the IEEE 118 busbars test power network and the results obtained were analysed. Finally, some conclusions that provide a valuable contribution to the understanding of the power system security analysis are pointed out.
