The article provides a library for modeling relay protection in a Simulink environment.
In addition to the derivation of the method of nodal potentials, we consider a method for calculating electrical circuits using this method.
Along with solving electrical circuits according to laws of Kirchhoff and the method of loop currents, the method of nodal potentials is also used. Its use is rational if the number of nodes is greater than the number of independent loops in the circuit.
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.
