Why do the rotors of the generators do not spin anymore?
The rotors can be set to spin by editing the display options. Select Options >> Oneline Display from the main menu. On the display options tab of the oneline display options dialog, there is a field labeled “Change in Gen Rotor Angle per Refresh (degrees)” If the value is set to zero, the rotors appear stationary when the diagram animation is in motion. This value can also be set on either the Miscellaneous Options drop-down menu of the Oneline Options toolbar or by selecting Options >> Oneline Display >> Misc. Options (satellite menu) then specifying a value in the Gen Angle Change field.
