摘　　要：在线性化分析理论的基础上,给出了可以用于电力系统的向量场正则形理论的基本理论。其核心是通过非线性向量场的正则变换得到线性向量场,再通过正则反变换得到原系统高阶解析解。研究了把这一理论应用于电力系统稳定分析中所必须解决的关键问题和计算技术。最后,展望了这一理论在电力系统分析中应用的前景。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.
