The disadvantage of most of the existing program solutions is inįact that they are primarily intended for high voltage power systemĪnalysis which features are: relatively small number of nodes (bus and Results through usage of modern graphical interface. PowerFactory enables more simple entry of data and overview of given Modern commercial software packages, such as ETAP, NEPLAN, PSS/E or Programs written in FORTRAN that read input data from the strictlyĭefined text files and represent calculation results in the same form. For last 30 years different computer programs haveīeen used for system state calculations. Power systems and adequate adjusting of the protective devices,ĭetermination of short circuit current rates in network nodes andīranches are crucial. During planning, due to optimal dimensioning of electric System is the basic precondition of reliability, quality and economical Understanding of load flow and voltage performances of the power Key words: load flow, short circuit calculations, Newton-Rapson,

Results were compared with other commercial programs. Which, upon simple optimizations, are efficient way of solving problems Used algorithms are based on classic numerical methods Provides fast and easy user interface as well as data exchange with Retrieved from Ībstract: Application intended for load flow calculation and shortĬircuit analysis of power distribution networks.
