Brazilian System Operator online security assessment system

This paper presents the practical experience of the Brazilian System Operator with the online dynamic security assessment. More specifically, it describes the adopted models, analytical methods and functions, performance, EMS integration, user interface and implementation issues. Examples of situations in which the online security assessment was very useful are also shown.
