Generator Display Objects

 

Generators are represented on the oneline as circles with a rotor symbol inside. The default rotor symbol is a "dog bone," but other symbols can be selected. Multiple generators at a bus are allowed, with each being distinguished by a unique character identifier.

Each generator symbol (except that corresponding to the slack) can be equipped with a circuit breaker (see that can be used to change the status of the generator. You may toggle the generator status by clicking on the circuit breaker while in Run Mode.

Generator fields are often placed close to the generator on the oneline to indicate the generator's MW/Mvar output or other information associated with the generator.

Run Mode

When animation is active, the default flow of the arrows emerging from the generator is proportional to its MW output. You can customize the appearance of this flow using the Animated Flows Tab of the Oneline Display Options Dialog.

Right clicking on the generator brings up the generator submenu. This menu is used to display a variety of information about the generator, including

• Generator Information Dialog
• Input-output curve
• Fuel cost curve
• Incremental cost curve
• Heat-rate curve
• Reactive capability curve

Edit Mode

To add a new generator to the case, select Network > Generator from the Individual Insert ribbon group on the Draw ribbon tab. Then, place the cursor on the bus where you would like to attach the generator, and click with the left mouse button. This calls up the Generator Dialog. The bus number is automatically determined from the bus to which you attached the generator. The ID field contains a an alphanumeric ID used to distinguish multiple generators at a bus. The default is '1'.

Enter the size, the thickness of the lines (in pixels) used to display the device, orientation, rotor symbol, and other parameters for the generator. Each generator can optionally contain a circuit breaker for connecting or disconnecting the device in Simulator. Use options found with the Display Object Options on the Oneline Display Options dialog to specify if a circuit breaker should be shown. Select OK to add the generator. If you do not want to add the generator to the case, select Cancel.

To modify the parameters for an existing generator, position the cursor on the generator and right-click. This again brings up the Generator Dialog. You can then change any parameter (be careful in renumbering an existing generator). Use the Formatting ribbon group commands to change the color, line thickness, and other display parameters.
