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.
