Article Preview

A new Structural analysis method of voltage stability in large power grid is proposed based on the eigenvalue Method in this paper. the method establishes an improved current injection model of Y+D matrix of the topological structural characteristics, which is helpful to the study of mechanism of voltage instibility. Through calculating the eigenvalue of the Y+D matrix, influence of network topology structure to the voltage stable in the electrical power system is analyzed. The simulation results show that voltage stability has close relationship with topological structure of the power network structure.
