Transient Stability Analysis
I*SIM - SKM System Analysis Inc. (SKM)
PTW I*SIM is a program for transient stability analysis. It is designed to simulate system response during and after transient disturbances such as faults, load changes, switching, motor starting, loss of utility, loss of generation, loss of excitation, and blocked governor events. I*SIM is designed to study today's most challenging simulation problems in one convenient and easy-to-use program.
