Hi all,
If our plant is only 600V and is off-grid and supplied solely by 3 x 1200 kW Natural Gas Turbine Driven Generators at 600 V operating at 2 out of three at normal operations, do we need to perform dynamic or transient stability? All our motor loads are induction motors and large ones have VFDs.
I was under the impression that we need stability analysis if we have in-plant synchronous generators (or synchronous motors) connected in parallel with grid. Or, if we have in-plant generators (off-grid), interacting with in-plant synchronous motors
