Development of Clarke and Park Transforms Visualization Software Using Python

Three-phase electrical systems are commonly utilized in many industrial applications. In particular, they are used in transmission and distribution lines, as well as in the operation of asynchronous motors. Despite their widespread use, three-phase electrical systems are challenging to model and analyze because of the time-depending parameters. In order to overcome these challenges, some mathematical methods such as Clarke and Park transforms are performed. In this study, to ease the understanding of Clarke and Park transforms, a software application is developed. The application demonstrates the effects of changing the voltage, frequency, and phase parameters on the Clarke and Park transforms. In the proposed application, users can convert 3-phase (ABC) axes to 2-phase (αβ) axes, 2-phase (αβ) axes to reference (dq) axes. Application can also convert 2-phase axes to 3-phase axes with the inverse Clarke and Park transforms. During the transformation, it visualizes three separate sequences with a single parameter input, eliminating the need for repeated parameter input for each axis. Mathematical modelling and user interface development of the application are performed in Python programming language.
