Abstract :
This paper presents a new solution for management of the risk of oscillatory instability. The technique combines a measurement-based stability indication method with high-quality wide-area monitoring. The system provides information to localize poorly damped oscillations, identify causal factors and propose appropriate responses. Depending on the risks presented, the actions may be real-time control actions, or off-line analysis leading to targeted control design review. The conceptual basis and the practical implementation of the technique are presented.
