An intelligent substation design environment

Summary form only given. A knowledge-based object-oriented tool has been developed to integrate, preserve and support tasks inherent to substation design, bringing together the principal design activities and related data. It produces a number of potential designs which satisfy specified design criteria such as short-circuit levels, insulation withstand voltages and substation reliability. The outputs of the tool include: (1) the definition of the main substation equipment; (2) their general electric specifications; (3) the single-line diagram of the station; (4) a detailed report describing the design performance including reliability measures and cost.
