Solving a Power Flow
To solve a power flow, click 
Power Flow. The power flow solves and displays results using the options you select on the Power Flow tab and on the tabs in the Power Flow Options dialog box. To open this dialog box, click Power Flow > PF Options.
After the power flow has solved (indicated by results on the one-line), you can display various other results by clicking the appropriate buttons on the Power Flow tab.
By default, text reports are not generated. You can generate detailed or summary reports by specifying them in the Text Output tab of the Power Flow Options dialog box.
