Knowledge based system support for introductory power system network analysis on personal computers

The application of artificial intelligence for knowledge-based systems (KBSs) is reviewed and applied to the basic power system network analysis problem. A frame-based KBS has been developed to assist students in preparing data for power flow analysis. The prototype for a power flow knowledge-based system (PFKBS) is an example of a shallow knowledge system. The details of an implementation for a simple power system are used to highlight the difference between a frame-based approach and a conventional FORTRAN approach. The data structures used within the developed frame-based KBS are presented in sufficient detail for anyone to regenerate the database. The user interface is illustrated for a small power system. The method of preparing data for the power flow as a sequence of knowledge bases is discussed for the example system
