General purpose symbolic simulation tools for electric networks

Abstract

Research results on the use of computers to solve simulation problems in a way closer to human thinking are reported. With the aid of techniques in artificial intelligence, database systems, and computer graphics, a set of general-purpose Lisp and Pascal based simulation tools have been developed. Each of these tools solves a specific problem in some stage of simulation. Rule-based and object oriented symbolic manipulations are extensively used. The tools provide more powerful and accurate modeling capability for complex objects, and permit simplicity and flexibility in implementation. They are used to study electrical transient problems, optimal load flow problems, linear control systems, and other simulation problems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
