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.

Reset: After running a simulation, you need to reset in order to change breaker/switch configuration or to re-run the simulation.

Run: Run a simulation using script. The script needs to be created first. The script selected on the Dynamics Stability toolbar is run.

Step: 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.

Bus Fault Dynamic 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.

Toggle ATS Source Bus & Run Simulation: 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.

Generator Excitation System Step Test: 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.

Generator Governor System Step Test: 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.
