Abstract
A new method of integrating the nonlinear differential systems with wide eigenvalue range encountered in power system transient studies is developed. A state transition matrix is employed and a very efficient procedure for its calculation is included. For typical problems this integration method has permitted step sizes a factor of 100 larger than conventional numerical integration algorithms without loss of accuracy or significant increase in computing time per step.Keywords
