Abstract
ABSTRACT Modern experimental investigations of power system stability are based on accurate physical models for the simulation of actual systems in the laboratory. Power system components are simulated by scale models; e.g. micro-alternators for large synchronous machines. Other parts of power systems like transmission lines and transformers and circuit breakers are easily represented in those models as well. However, when the studies involve sequences of events to take place in power system with certain time delays, classical methods of disturbance application prove to be poor. In this paper a method of power system disturbance representation using a ROM-based digital circuit is introduced. The ROM is programmed to the sequence of events to take place in the system under study. A method of sequential circuit design using programmable ROM and other integrated-circuits chips to adjust for the required time delays is applied. The circuit has been designed to represent processes of automatic reclosure of fau...
