I*SIM
- Transient Stability Analysis
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.
Benefits:

|
|
Increase flexibility with a powerful graphical builder
for user-defined controllers.
|
|
|
Save time by running multiple case scenarios from a
single action.
|
|
|
Communicate designs more easily with professional
reports and graphs.
|
|
|
Evaluate alternatives quickly and easily to establish
an optimal design.
|
Interface Options:
