A Windows based GUI software tool for system protection simulations in PC environment

A graphical Windows based software tool to facilitate the analysis and training of system protection is presented in this paper. This tool is developed using Microsoft/sup R/ Visual Basic for the Windows Environment. This software package contains two components: CONFIG and DEMO. CONFIG is a user knowledge database. It is used by experienced protection engineers to create a comprehensive database for the inexperienced protection engineers. DEMO is used by the inexperienced protection engineers. DEMO can access the database created in the CONFIG, but DEMO cannot modify the database. CONFIG and DEMO have similar GUI features. Through DEMO the engineers can simulate and study the system protection. In order to effectively link the protective device settings and the fault with corresponding circuit responses, a new number system conversion algorithm is also introduced.
