Characteristic Analysis of Electromechanical Disturbance Propagation for Power System

WANG De-lin WANG Xiao-ru (School of Electrical Engineering,Southwest Jiaotong University,Chengdu 610031,Sichuan Province,China)  
It is presented that the laws of electromechanical disturbance propagation in a discrete uniform chain power system.Through the Laplace and Z transformations,it represents the varying features of electromechanical disturbance in a uniform chain network using the family of Bessel functions;the growing or attenuating laws are the same as that of electromechanical wave in a continuum model along the corresponding transmission media.Furthermore,the time of electromechanical disturbance arriving at any bus in the discrete model is also the same as that of electromechanical wave arriving at the corresponding bus in the continuum model. Finally,the simulation based on a 64 generators ring system validates the rationality and correctness of both the discrete and continuum models describing electromechanical disturbance propagation in the power systems.
