The article provides a library for modeling relay protection in a Simulink environment.
Relays, simulation of relays, current and voltage relays of maximum and minimum action, relay return coefficient, relay bounce.
A differential relay is used in the implementation of the basic protections of various equipment: generators, transformers, power lines, etc. The use of a relay with a braking characteristic prevents the non-selective action of the protection.
Relay is the main element in modeling relay protection. A relay is a non-linear element that changes its output value in steps with a certain change in the input quantity.
