Applied to Theory of Normal Forms of Vector Fields for Power System Stability Analysis

On the basis of the linearization analysis theory, the normal form of vector fields theory which can be applied to power systems is presented in this paper. The key idea of the theory is the use of nonlinear normal form transformation to obtain linear vector fields, and then the use of normal form inverse transformation to solve the high order analytic solution of the original system. The key problem and the calculation technology in application for power system stability analysis are researched. The application prospect of the theory is predicted further.
