Application of Volterra İntegral Equations and Discrete Borel Transformations to Transient Switching Modes of Networks and Systems

Abstract

Calculations and analyzes of transient processes during switching and short circuits on the section of the electrical network and systems involved in power transmission lines are a rather complex problem. Inaccuracies made in the choice of equivalent circuits and calculations using the MATLAB Simuling programs and others increase the errors. In a number of cases of automatic reclosing, and in problems with nonzero initial conditions, transient processes require special calculation programs. The analysis of transient processes plays a special role in the selection of elements of relay protection and automation systems in the analysis of design calculations. In many cases, when carrying out computational project work, rather expensive, sometimes not very accurate programs and software are used. Therefore, carrying out design calculations for simple cases of switching and short-circuit, sometimes turns into inadequate and undeserved dependence on foreign specialists. The presented article examines the results of transient processes and voltages when the transmission line is turned on to a sinusoidal voltage source and, as a result, automatic reclosing.
