https://thales1330.github.io/PSP/

A power system simulation tool for load flow, short-circuit, and stability studies. It features numerical solution methods like Gauss-Seidel and Newton-Raphson, harmonic studies, and modeling for synchronous generators, induction motors, transformers, and capacitors. The software includes a power element editor and supports complex mathematical expressions via the fparser library.

What's inside PSP-UFU

  1. Overview of PSP-UFU power system simulation software

    PSP-UFU (Plataforma de Sistemas de Potência da Universidade Federal de Uberlândia) is a free and open-source (FOSS), multi-platform, and multi-lingual software designed for power system studies. It features a Graphical User Interface (GUI) and Computer Aided Design (CAD) tools that allow users to build electrical transmission networks and control systems using visual elements. Results are visualized via linked text elements on the main screen, as well as table and graph editors. The software is intended for research, education, and industrial applications.

  2. Overview of PSP-UFU Power System Platform

    PSP-UFU (Power Systems Platform of Federal University of Uberlândia) is a cross-platform, multilingual, Free and Open-Source Software (FOSS) designed for power system studies. It provides a Graphical User Interface (GUI) and CAD tools to construct electric transmission networks and control systems using visual elements. It is intended for research, education, and industrial applications in electrical power systems.

  5. Overview of PSP-UFU capabilities

    PSP-UFU (Power Systems Platform of Federal University of Uberlândia) is a free and open-source (FOSS), multi-platform, and multilingual software designed for electrical power system studies. It features a Graphical User Interface (GUI) and Computer Aided Design (CAD) tools for constructing electrical transmission networks and control systems using visual elements. Results are accessible via linked text elements on the main screen, as well as table and graph editors. The software supports the following types of studies:

    • Power flow
    • Short circuit calculation
    • Harmonics
    • Transient and dynamic stability

  6. Use constants to define fixed numerical values in simulations

    Constants are real numerical values that remain unchanged throughout the entire simulation period. They feature a single output node that can be connected to any input node of control elements. Common use cases include defining target values or signal offsets.

  8. Implement ATP-PSP Bridge for EMT simulations

    The ATP-PSP Bridge enables real-time data exchange between ATP and PSP for Electromagnetic Transient (EMT) simulations. This bridge now includes support for Linux/POSIX, allowing EMT co-simulation to run on Linux environments.

  10. Implement Transmission Lines using the Pi Model in PSP-UFU

    Transmission lines in PSP-UFU are implemented as balanced $\pi$ models. They are used for transmission and distribution of power systems. The model consists of series resistance ($r_L$), series inductive reactance ($x_L$), and total shunt capacitive susceptance ($2b_L^d$).

    Constraints and Requirements:

    • The model is balanced and does not include mutual impedances between phases.
    • Lines must be connected between two buses of the same nominal voltage; otherwise, an error message will be displayed.
    • For harmonic studies, a passive filter can be simulated by arranging a line (without shunt susceptances), a bus, and a capacitor in series.

  12. Understand the PSP-UFU stability tool structure

    The stability tool treats Power Electric Systems (SEP) as dynamic problems using Algebraic-Differential Equations (ADEs) in the time domain:

    • State Variables (x): Dynamic variables.
    • Algebraic Variables (y): Initial values correspond to bus voltages and angles calculated during load flow.
    • Input Variables (u): User-defined constants throughout the calculation.

    Dynamic models are used for synchronous machines, ZIP loads, and induction motors. Other components (transmission lines, transformers, and shunt elements) use the same models as the load flow analysis.
