Don't know what the reasons are that call strt number of times. The purpose of strt is to help debug the model errors or missing models. I don't think that it is a good practice to run strt a couple of times, as the power flow conditions may not be what you want (i.e., the condition at t=0-, may not be the one that you want to study).

However, for your particular question, you can set loop based on the return of okstrt() function. something like,

# initialization
bStrt = 1;
while bStrt:
    ierr = psspy.strt();
    if ierr > 0:
        print 'STRT Error with code:', ierr;
        break;
    bStrt = psspy.okstrt();

# run
