The article provides a library for modeling relay protection in a Simulink environment.
Using modern software tools, such as Matlab / Simulink, can significantly simplify the analysis of various complex systems. Matlab scripts allow you to automatically run Simulink schemes with changing various parameters.
Emergency components – parameters that occur during any switching in the electrical system. They are one of the most informative values and are used in highly sensitive protection functions, for example, to implement blocking during swings.
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.
