Model and performance simulation for overcurrent relay and fault-circuit-breaker using Simulink

摘要

Simulink is an interactive software tool for modelling, simulating and analysing dynamic systems, which is showing optimum results in all fields of engineering. This article describes how a model of a circuit breaker controlled by an overcurrent relay was built to illustrate the tool's use in coordinating and selecting power network protection elements under stable, transient or no voltage power conditions.
