| Abstract: | The sympletic geometry algorithm is utilized to implement numerical calculation of power system transient stability.Comparative study of sympletic geometry algorithm and implicit trapezoidal rule and classical Runge-Kutta methods shows that the sympletic geometry algorithm is has superiority in either calculation accuracy or numerical stability over the classical approach.Therefore,this new method should be more suitable to numerical analysis of transient stability and other like-wise problems. |
