The article provides a library for modeling relay protection in a Simulink environment.
Simulation of relay protection in Matlab / Simulink, description of relay protection and automation algorithms, relay protection in simple words.
Overcurrent protection – protection used on almost all types of electrical equipment. This protection responds to an increase in the current flowing on the protected equipment.
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.
