电力系统暂态稳定评估（TSA）关系到电力系统安全稳定运行,传统的TSA分析方法——能量函数法虽然可靠有效,但仍存在问题。本文通过分析能量函数法所涉及的模型的建立、能量函数的构造、临界能量的确定,指出存在的问题,提出改进建议。

Power system transient stability assessment（TSA） is an important issue related to power system security and stability.Though the energy function,the traditional methods of TSA,is reliable and effective,there is also some problems within the energy function.This paper indicates the problems by analysising the construction of the model involved in the energy function,the structure of the energy function and the determination of the critical energy,and thus pretends improvement suggestions.
