Turbine FV is a stability enhancing method used to protect power systems against the loss of synchronism after extreme contingency events. To avoid unnecessary FV action, smart control schemes can be used based on real-time instability prediction. In

The ball valve effect occurs when an obstructing lesion allows inspiration of air, but opposes the egression of exhaled air, causing gas trapping. The phenomenon is commonly described secondary to bronchial foreign body inhalation. However, it is les

Turbine fast valving is one way to preserve the stability of power systems in case of emergency excess power. The determination of optimal setting parameters of turbine fast valving is a rather complicated task. It is connected with the necessity to
