Original Abstract

This paper deals with the short circuit current calculation of the load synchronous generator. The short circuit current equation is compounded of the three parts. The first part of the time behavior is a subtransient state, the second part is a transient state and the last part is a steady state. These states compose a total equation of short circuit current together and are calculated by a derivate equation on base of induced voltages, a d-q axis reactance and machine parameters. These currents are not a problem to measure in the small machines but these currents are easier to calculate in the machines with nominal power MVA and bigger. It is im-portant to know generator time constants and all reactances (d-q axis). The Induced voltages are derived from generator currents and voltages in this paper too.
