Abstract
In a fault-tolerant power system the failures must be detected and isolated saving the operational state of the system. So we propose a model for performance evaluation of fail safe behavior concerning automation and protection systems. Fuzzy Safety measures are computed for the most significant protection and automations types. The paper explains fuzzy safety analysis for the electric generator (EG) protection and automation system. Power system electric generator (EG) is protected to various types of faults and abnormal workings. The protection and automation system (PAS) is composed of waiting subsystems, which must properly respond to each kind of dangerous events. An original fuzzy logic- system enables us to analyze the qualitative evaluation of the event –tree, modeling PAS behavior. Fuzzy - set logic is used to account for imprecision and uncertainty in data while employing event-tree analysis. The fuzzy event-tree logic allows the use of verbal statement for the probabilities and consequences, such as very high, moderate and low probability.
