The authors propose a method of convergence acceleration for iterative solutions of SLAE from electrical network modeling systems. This method was based on the neutralization of the transfer matrix dominant characteristic values. By the example of AC electrical networks’ computation defined with matrices with complex numbers the dependence of iteration number of Gauss-Seidel method on the number of neutralized roots was shown. The calculated data corresponded well to theoretical convergence estimate obtained from the characteristic equation roots. The ability of additional convergence acceleration by means of root neutralization was shown in the successive over-relaxation method.
