Torrit: A GUI-Based Power System Simulation Platform

TL;DR

Torrit is a Python-based GUI application designed for power system simulation, enabling educational and practical exploration of transmission system operations through an interactive interface.

Contribution

Introduces a free, flexible, GUI-based power system simulation platform called Torrit, developed in Python, with core functionalities for power flow and state estimation.

Findings

Supports executing, saving, and re-opening projects

Allows operations like create, delete, copy, move on a graphical canvas

Provides a foundation for future extensions in power system education

Abstract

An adequate education on power system operations and controls requires a hands-on experience on a graphical user interface (GUI) based software. At present, most commercial software do not have free editions with high flexibility and most freeware do not have good interfaces. This paper introduces a GUI-based application called "Torrit" for executing operations of power systems, especially for transmission systems. It is written in Python for it's rapid development ability. Torrit's main window includes a single canvas with some standard graphical interactions like create, delete, copy, move, double click etc. The beta version of this application is the focus of this paper that allows executing, saving and re-opening a project in three different modes: per unit computations, power flow, and state estimation. However, it is still in a rudimentary stage and many extensions are planned for future to match the needs of both academia and industry.
