Simulation Commands
The following commands are available for running dynamic simulations. You need to select the appropriate equipment in the one-line to run some of these commands. These commands are also available from the right-click context menu.
| Command | Description |
|---|---|
|
Reset |
After running a simulation, you need to reset in order to change breaker/switch configuration or to re-run the simulation. |
|
Run a simulation using script. The script needs to be created first. The script selected on the Dynamics Stability toolbar is run. |
|
|
Run a simulation using script, one step at a time. The simulation advances by the time step specified in the Dynamics Stability Options. You need to select the Step command multiple times to step through the simulation. |
|
|
Simulation is run for a fault on a bus selected on the one-line. The options specified in Dynamics Stability Options are used for the fault time and the duration. The same simulation can also be run by double-clicking on a bus in the one-line window or by right-clicking on the bus and selecting Bus Fault Dynamic Simulation from the context menu. |
|
|
Changes the ATS connection to an alternate source and runs the simulation. You need to select the ATS needs in the one-line before choosing the menu command. You can also double-click on the ATS in the one-line to run the same command or right-click on the ATS and select Toggle Source Bus and Run Simulation from the context menu. |
|
|
Runs a step response test on the excitation system of the generator selected in the one-line window. This test enables you to see the effect of increasing the excitation by a specified amount. The AutoPlot plots the per-unit generator terminal voltage and the per-unit field voltage. The test treats the generator as isolated from the network. It can also be performed by double-clicking on the generator exciter symbol in the one-line. |
|
|
Runs a step response test on the governor system of the generator selected in the one-line. This test enables you to see the effect of increasing the load by a specified amount. The generator speed changes. The AutoPlot plots the per-unit generator prime mover power and the per-unit speed. The step test can also be performed by double-clicking on the generator governor symbol in the one-line. |
|
|
Open Switch and Run Simulation |
Runs a simulation starting with the opening action of the selected switch or fuse or breaker. |
|
Close Switch and Run Simulation |
Runs a simulation starting with the closing action of the selected switch or fuse or breaker. |
