    Powerflow & Short circuit Assessment Tool

    PSAT is a full-featured powerflow program that includes table-driven data manipulation and a flexible single-line diagram (SLD) capability. It can be used for stand-alone powerflow analysis or for data exchange with the other DSATools™ modules.



    • Creation, examination, and modification of powerflow models and cases
    • Powerflow, short-circuit, and system reduction analysis
    • Harmonics analysis using Harmonics add-on module
    • Contingency assessment, including thermal loading and voltage studies
    • Production of SLD for powerflow data and results reporting
    • Set-up of initial conditions for other DSATools™ modules



    • Various data-checking and powerflow results verification options
    • Robust powerflow solver engine
    • Support for wide range of models/li>
    • Support for Python scripts or macros to automate powerflow activities
    • SLD diagram creation by using drag-and-drop approach
    • GIS-based SLD
    • Various options to display powerflow data and solutions on SLD
    • Contour display for many powerflow quantities and for imported user-defined quantities
    • Powerflow case comparison
    • Capability of importing powerflow data in variety of formats
