PowerFactory is an integrated software solution developed by DIgSILENT for the modeling, simulation and analysis of electrical power systems. It is used by utilities, grid operators, consultants, industrial companies and research institutions to study generation, transmission, distribution and industrial networks. The software provides a unified database and calculation engine that allows users to perform steady-state, quasi-dynamic and time-domain simulations within one environment. It supports detailed modeling of network components such as generators, transformers, lines, loads, protection devices and control systems. PowerFactory enables analysis of load flow, short-circuit behavior, protection coordination, stability performance and network security. It is designed to support planning studies, operational assessments, grid integration of renewable energy sources and compliance with international standards. The system combines graphical modeling, data management and simulation tools in a single platform to ensure consistency across different study types and scenarios.
