Designing Database for Decision Support System for Development of Electrical Grid

The design of an electrical grid raises the issue of optimizing the selection of nomenclature parameters because of the variety of used equipment types. It is necessary to develop a database for solving this problem that includes the determination of the main elements of transformer substations and power lines, structuring their parameters for calculating the criteria of evaluating the effectiveness of the decision to select power equipment. The conceptual model of a transformer substation and power transmission line was developed on the basis of the analysis of the subject area, the main elements and their properties were determined. A logical and physical model based on a relational database-management system was developed. The received models can be used for develop a database, a program for calculation of the criteria for evaluating the efficiency of the decision on the select of the power equipment. The development used an object-oriented approach, methods of system analysis and semantic modeling, methods of designing relational databases.
