Example 3: Photovoltaic System
This section provides an example of a photovoltaic system. To view the example and perform the tasks, open the Photovoltaic.dez that is available in the Sample directory.
Figure 1: Photovoltaic Example
- Click Power Flow, and then click Solve. The power flow results are displayed on the one-line.
-
Select Short Circuit to open the short circuit focus.
- Click Momentary if it is not already selected, and then click Fault Bus(es).
- View the momentary currents on the one-line. At every bus compare the fault current contribution from each branch. For instance, PVC-1 bus has a small fault current supplied from the photovoltaic PVC-1, and a larger current from the bus COMBINER-1.
- Click Arc Flash to view the arc flash hazard results.
- Click Short Circuit Options and select the Arc Flash Hazard tab. Note the options circled below.
- Change the option Calculate Arc Flash Using to Momentary and view results at bus PVC-1. The result is not calculated because there is no trip device modeled between the faulted bus and the photovoltaic source PVC-1.
