Relay protection

Relay protection and automation, relay protection and automation, relay protection modeling, relay modeling, sensitivity, selectivity, reliability of relay protection.

Simulation of a symmetric components filter

Symmetric components are very important parameters used in relay protection to implement protection of various equipment. They allow you to implement more sensitive and specific types of protection.

Simulation of Impedance Relay

Impedance relay is another type of relay used in relay protection. The difference of this relay is that it is a relay with two input quantities, and its operation is determined by the input value (measurement) falling into a certain response characteristic. The measurement in this case is the complex resistance Z.

Simulation of Time Delays

Time delays are one of the main elements in modeling relay protection. They allow not only to create a delay in the operation of the protection, but, on the contrary, to extend the action of relay protection.

Simulation of relay protection in Simulink

The Matlab / Simulink software package allows you to simulate not only electrical networks, but also much more, including relay protection and automation algorithms.
