Abstract
The efficiency analysis of Runge-Kutta family methods for solving ordinary differential equations (ODEs) in order to simulate typical transient processes in AC machines is performed in this paper considering the choice of the set of variables in the state space vector. The detailed analysis of the AC machine ODEs and their numerical solution is performed based on the estimation of the higher order derivatives and the numerical solution error using constant step solvers. The influence of the Runge-Kutta solver parameters and the choice of variables in the state space vector on the numerical performance is shown, and a method for the machine specific optimization of the ODE solver is proposed. The AC machine used for the numerical experiments is described by Park's two-axis model which is extended with the effect of rotor current displacement and elastic coupling with the load in the mechanical system.
