Parallel Modeling of Transient States Analysis in Electrical Circuits

摘要

In this paper a speculative method for parallel modeling of transient states analysis of electrical circuits in distributed systems is presented. Solving systems of linear or nonlinear ordinary differential equations that describe the transient states is a purely sequential process. The proposed speculative computation method converts involved sequential computations into intensively parallel ones. The general idea of this method is based on decomposition of the analysed time domain into sub-intervals in which parallel solving is done based on speculatively assumed initial conditions. Parallel computations in subsequent time sub-intervals are conducted with the use of sequential numerical Runge-Kutta method. Application of the method for simulation of functioning of a DC motor with a controlled integration step size is shown.
