CHSB Monitor Machine Apparent Impedance

psspy.chsb can monitor apparent impedance by setting STATUS(5)=22. Did anyone know how this apparent impedance being calculated during time domain simulation. Moreover, is there any difference between calculating apparent impedance for wind generator and synchronous generator. Thanks !

The apparent impedance is calculated from the apparent power S (P + jQ) and the voltage at the generator terminal (U**2/S).
