Generator Start-Up
Using full frequency-dependent machine and network models, the Generator Start-Up module analyzes cold-state starting of generators under normal and emergency conditions. The entire generator start-up process is modeled, including automatic control relay simulation and the dynamic behavior of exciters/AVRs, governors, turbines, and Power System Stabilizers (PSS). You can simulate the starting of generators, connection of generators to the network before reaching synchronizing speed, acceleration of motors, action of MOVs, and operation circuit breakers.
