Abstract: Mid-and-long term voltage collapse of large-scale power system is a slow process. The occurrence and changes are closely related to the dynamic behavior of slow components in system. Therefore, study on mid-and-long term voltage stabilities requires using simulation software that reflects slow dynamic process. Five simulation software packages, namely PSS/E, PSD-FDS, Eurostag, PSASP and DSATools are selected in this study. Practical analysis and evaluations are made to compare functions of these software packages in mid-and-long term time-domain simulations. Through simulation experiments, software parameters investigation and practical application examples, comparisons are performed on several aspects including principle and algorithm, simulation scale, components model and user interface. The results indicate that PSD-FDS provides better models and functions suitable for China power systems and precedes other software packages in mid-and-long term voltage stability research.
