Parallel computer graphics simulation of the Lebanese Electric Power System

A microcomputer software package that provides a computer graphics simulation of electrical power systems in a parallel-processing configuration is described. It facilitates a user-friendly environment to configure the electrical network so that hypothetical or actual substations and transmission lines can be added or deleted to simulate any change in the network´s performance. The package runs in parallel with the load-flow program and is used as a computer-aided design tool to provide a graphical representation of the Lebanese electrical network, which is composed of 127 nodes. The choice and implementation of the hierarchical data structure used to store the network´s model are examined. Graphic-oriented reports, context-sensitive HELP, and online documentation make the package a powerful tool that can analyze anything from a few buses to an entire network. An important feature of the package is its fast throughput of execution.<>
