Generic protective relaying framework for HV grid network

This article presents an alternative for the protective relaying framework for high voltage (HV) grid network specifically for the 33kV substation. The schematic drawings of the protective relaying panels of the 33kV substation were used to be created manually in AutoCAD software. In order to create the generic framework, a plugin in AutoCAD was developed to automate the generation of the schematic drawings of the protective relaying panels of the 33kV substation. The plugin was written in C# .NET programming language and developed using Microsoft Visual Studio which supports developing C# .NET applications. Development of the plugin were split into two stages, the first stage was developing the algorithm for back-end of the plugin, and the second stage was developing the graphical user interface (GUI) for the front-end of the plugin. Both the back-end and the front-end had to be integrated together in order to create a fully functional plugin. The plugin was tested to check if it could generate the schematic drawings automatically without the need to open them in AutoCAD.
