Simulation

Simulation of electrical networks and relay protection, analysis of the protection.

Library for relay protection simulation in Simulink

The article provides a library for modeling relay protection in a Simulink environment.

Simulation of Frequency Filter

In a previously published article, an option was presented to calculate the frequency of an electrical signal from a transition through zero. This article provides an example implementation of a frequency filter.

Method of Nodal Potentials: Methodology

In addition to the derivation of the method of nodal potentials, we consider a method for calculating electrical circuits using this method.

Method of nodal potentials: conclusion of the 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.

Loop currents method for calculating electrical circuits

When calculating electrical circuits, in addition to the Kirchhoff’s laws, the circuit current method is often used. The method of loop currents allows you to reduce the number of solvable equations.
