COMPARATIVE ANALYSIS OF METHODS OF CALCULATION IN TRANSIENT AND WAVE PROCESSES IN ELECTRIC CIRCUITS

Berzan, Vladimir

The problem of calculating the transient and wave processes in the circuits with the concentrated and distributed parameters is examined. A comparative-qualitative analysis of the analytical and numerical methods used for these purposes was carried out, indicating the advantages and disadvantages of their application. It is presented algorithms for applying the examined methods. It is found that numerical calculation methods have many advantages in studying stationary and dynamic processes in the natural sequence of processes course in the circuit. It is recommended to use the finite difference method. It is presents the main phases of realization of the application of a numerical calculation method and results of the comparative and qualitative analysis of the analytical methods (classical, state variables, frequency, stationary waves, Fourier transform, operational, traveling waves) and numerical (finite difference, finite element, finite volume).
