Short-circuit analysis is essential for determining the fault current rating of different protection devices installed in a power system network. Usually, the inaccuracy in short-circuit current calculation is due to the fact of neglecting the effect of load during short circuit analysis. This paper shows the symmetrical short-circuit analysis of a balanced grid considering the effect of loads using the instantaneous p-q theory based load models. Comparison of the results obtained by using the p-q theory-based load model with the MATLAB/Simulink three-phase dynamic load model establishes better computational performance in a real-Time environment without losing much in accuracy.

Abstract
Short-circuit analysis is essential for determining the fault current rating of different protection devices installed in a power system network. Usually, the inaccuracy in short-circuit current calculation is due to the fact of neglecting the effect of load during short circuit analysis. This paper shows the symmetrical short-circuit analysis of a balanced grid considering the effect of loads using the instantaneous p-q theory based load models. Comparison of the results obtained by using the p-q theory-based load model with the MATLAB/Simulink three-phase dynamic load model establishes better computational performance in a real-Time environment without losing much in accuracy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
