SESA an expert system for auxiliary power services design

Very few applications integrating expert systems with CAD software have been developed in the past given the lack of functionalities and methodologies needed for such development. Some applications require such an integration and have to be developed with novel approaches. SESA is a tool which assists the generating station´s auxiliary power system designer in making the optimal selection and layout of equipment required for such applications. SESA is an open system which includes, at the present time, two modules: an expert system (with all the rules applicable to such a design process) coupled with the layout and drawing facilities of Autocad (to view the design in progress). Using SESA´s expert system module, a generating station´s auxiliary power system single line diagram schematic is produced at the conclusion of the expert system. With the experience gained through SESA´s development, the authors conclude that it is now possible to integrate expert system applications with CAD software. Refining the functionalities and methodologies used in SESA´s development would lead to a more extensive use of applications requiring the integration of such environments.<>
