| Abstract | This article shows an analysis of the effect of generator models and load models on the results of the transient stability study of a power system. The analysis includes the classic, transient and subtransient models of generators, and the simulation of loads as constant impedance, constant power, constant current and a specific combination of constant power with constant impedance. A commercial software was used as a tool to analyse a power system whose basic solution is documented in the literature. The results are the evolution of the main variables and the critical clearing times for a specific line, with a three-phase fault in a particular location. The results indicate that the subtransient model for generators and the constant power model for loads are the more conservative conditions of simulation for the analysed example. |
