Data Base Environmennt for Power System Simulation Models

Abstract

This paper describes the data base approach to power system analysis studies, contrasts it with the traditional stand-alone application approach and discusses the issues which should be considered in developing a data base management system. The discussion is based on the experience gained in developing and implementing a power system data base management system at the Electricity Supply Commission (South Africa). The practical use of a central data base management system, together with a library of application programs and an interactive computing environment contributed significantly to the power system planning process in which individual engineers can work efficiently and interact among themselves using common data and analysis tools.
