while Dynamic simulation, Generators are converted as Voltage source with impedance...

edit

Dear All, Good Afternoon.. While running Dynamic simulation, Genrators are Load are converted as constant Voltage source with Impedance and constant MVA load respectively... Now, when trying to run simple Load flow and incorporate changes in values of Generators, (after the dynamic study)... PSSE showing the msg that "Generators are converted" and not entertaining to perform Load flow further... How to revert/normalize Generators..??? Any one please, who may guide.>??? I am using 50 bus University version of PSSE 33..
