Hello, This isn't strictly a control question, but it relates to a current control problem. We're modelling parts of a plant power generating system and need an indication of approximate process dynamics. Following may not be in correct terminology.
Can anyone give me an indication of the natural frequency for a pair of steam turbine driven alternators, about 15MVA each, parallelled on a bus? That is, the frequency of torsional oscillation and power slew following a step disturbance. TIA
