Abstract
[Abstract] This paper illustrates an alternative implementation to automatic protection and supervision task using the basic principles of model-based fault-detection and isolation associated to the rule-based FDI with subsequent appropriate corrective actions. Hybrid systems may be precisely described by sequential function charts (SFC). Operation supervision of hybrid systems may be carried out simultaneously on the basis of such SFC description. As discrete event and continuous processes operate simultaneously in close cooperation, a strategy to diagnose such hybrid system by means of a structured methodology under SFC description tool on the IEC-848 standard is developed
