DIgSILENT PowerFactory Software

DIgSILENT Power Factory: The development of DIgSILENT (DIgital SImuLator for Electrical NeTwork) software began in 1976, and utilized the talent of many experienced power system engineers and software developers directly involved with the planning, operation and maintenance of power systems. Since the inception of DIgSILENT, the program has grown to incorporate a vast array of analysis features that are required to plan, operate and maintain any aspect of the power system.

The new DIgSILENT PowerFactory software is an integrated power system analysis tool that combines reliable and flexible system modeling capabilities, with state-of-the-art solution algorithms and a unique database management concept. The PowerFactory concept was initiated in 1993 when the decision was made to re-engineer the already successful DIgSILENT PowerFactory with improved solution algorithms and advanced software technology incorporating an object-oriented database. PowerFactory is setting new standards in functional integration, by incorporating a feature that can best be described as “Active Documentation”. This flexible feature allows the user to create detailed power system models in a single database, allowing model functionality to be easily extended to specify a wide range of steady state, time domain, frequency domain and stochastic system characteristics, for all analysis requirements.

PowerFactory incorporates an impressive and continuously growing list of simulation functionalities including:

  • Load Flow and Fault Analysis of complete AC/DC network representation, and allows meshed and mixed 1-,2-, and 3-phase AC and/or DC networks to be modeled.
