Using full frequency-dependent machine and network models, the Generator Start-Up calculation program 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 dynamic behaviors of exciters-AVR, governor, turbine /engine, and Power System Stabilizers (PSS). Generator Start-up program can be utilized to simulate detailed dynamic responses of the starting generator, test emergency loads including motors, MOV and others which are connected to the generator before it reaches to the synchronous speed and rated voltage.
