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