ANAFAS (Analysis of Simultaneous Faults) software is designed for short circuit calculations in electric power systems. It allows simulation of various fault types, including simultaneous and sliding faults; result reports oriented to fault points or monitoring points; automated circuit breaker rating studies; network equivalent calculation; and automated short circuit level evolution assesment.
Its graphical user interface provides an oneline diagram editor, which allows direct interaction with network elements and easy results visualization. Network data files in ANAFAS format are available for download in some public institutions' websites.
Among ANAFAS users are: public entities such as the National ISO and the National Energy Planning Company (EPE); Eletrobras companies; generation, transmission and distribution agents; major industrial consumers; independent producers and universities.
