Power System Post-stability Analysis Based On Eurostag

This paper compares the mathematical model of BPA(Chinese edition) imported by Electrical Power Research Institute of China with Eurostag developed by EDF and TRACTEBEL of Belgium. Based on full appreciation of models and methods of both BPA and Eurostag, the dynamic data transfer method is given. The data of North China Network has been studied with two softwares and the simulation results show good agreement for both power flow modules and dynamic simulation modules.This paper carry out power system post-stability analysis with Eurostag. This paper determine the state after low frequency oscillation according to the relation between oscillation frequency of low frequency oscillation and eigen value of small signal analysis, which is derived from a great deal of simulation projects.Cai Xiaoling(Power system and its automation) Directed by prof.
