Detect Instability With Preconfigured Modal Analysis Function Block—Close a contact based on critical stability indicators, such as oscillatory frequency and damping ratio, to assess power system health. Analyze up to 15 different modes from up to six different input voltages, currents, or real/reactive power. Detect unstable operating conditions, or check model predictions. Base alarms on mode amplitude, frequency, damping constant, and ratio for direct alarm or in combination with other conditions.
Measure the State of Your Power System—Send combined and conditioned measurements from an entire station to the energy management system (EMS). Isolate bad data, and alert operators of input failures.
