Unlike steady-state load flow analysis, transient stability simulation captures the dynamic behaviour of synchronous generators, induction motors, <strong>Automatic Voltage Regulators (AVR)<\/strong>, turbine governors, and <strong>Power System Stabilizers (PSS)<\/strong> over a time frame of seconds to minutes following the disturbance. It is an essential engineering evaluation for any network with synchronous generation, and for grids where sudden loss of stability would induce severe operational failures or catastrophic safety
