Abstract
In this paper, the merits of Adomian Decomposition
Method (ADM) have been investigated for the time domain
simulation of multi-machine power systems. ADM is an analytical
approximation method for the solution of linear, nonlinear,
deterministic and stochastic operator equations. It approximates
the nonlinearities in the equations using Adomian polynomial
series and that can form a rapidly convergent sequence of
analytic functions. We apply the ADM approach for simulation of
differential algebraic equations representing the detailed multimachine
power system. The ADM approach has been applied
on the widely used IEEE 3 generator 9 bus system and IEEE
10 generator 39 bus system for 3 fault simulations. In our
simulations we found that the ADM approach is faster than the
standard trapezoidal time integration method for the comparable
accuracy.
