For the Oscillogram Viewer in the COMTRADE format the functionality of constructing a vector diagram for analog channels has been added.
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.
When buiding vector diagrams for three-phase circuits, the choice of a base vector is now available. When choosing a vector as the base one, its angle is taken equal to 0°, and the angles of the remaining vectors are counted relative to it.
