The traditional curve-based method for variant symmetrical AC component of short-circuit current of power system is still commonly used, which takes much labor with lower accurate results. According to relative theories about electric circuit and synchronous generators' post-fault transient, a practical computerized method making use of node impedance matrix is proposed to calculate the instantaneous currents of a faulty power system. Compared with the traditional curve-based method, this method can calculate the currents with high accuracy and littleuser effort. Itcan automatically calculate the periodic componentsofvarying shortcircuit currentsateach time point, and it is verified by examples.
