Abstract
This paper describes a new method for rapidly detecting modal deterioration in large interconnected multimodal power systems. Any "sudden detrimental change" of an individual mode is detected using strategies derived from optimal detection theory. A statistical characterisation is used to establish reliable thresholds for detection of individual mode changes.
