Simulation and Results
As part of the example model setup, the user can perform one scenario. The user can enable or disable two three-phase faults on different model buses.
Scenario 1: Three-phase fault on Buses 7 and 9
The first scenario is about introducing a three-phase fault on Bus 7 at 10.1s by 0.01s and a three-phase fault on Bus 9 at 0.1s by 0.05s. The user can change these settings by going into the fault subsystem and changing the values of T1 and T2, configuring the fault activation and clear times, respectively. By default both faults are enabled, it is necessary to check the Enable option within the fault subsystems called Flt1_B7 and Flt_B9. By default, the ScopeView template for this example runs for 1s, so the three-phase fault on Bus 7 will not be observed since it occurs at 10.1s. In order to observe the effect of this three-phase fault in the model, it is necessary to increase the capture time in ScopeView or change the times T1 and T2 of the fault in Bus 7.
