| 摘 要： | 指出了传统的扩展等面积准则法（ＥＥＡＣ法）暂态稳定裕度定义方法的局限性及其适用范围，提出了可在电力系统状态变量的较大变化范围内，仍能正确反映系统受扰严重程度的ＥＥＡＣ法广义哲态稳定裕度定义数学模型及具体计算方法，并用实际系统的计算分析验证了所提出定义方法的正确性及有效性，从而为电力系统快速暂态稳定“扫描”分析及故障严重性排队提供了一个更为有效的暂态稳定格度定量指标。

| Abstract: | In this paper, the shortcomings and limitations of the transient stability marginbased on the extended equal area criterion (EEAC) method were investigated, and the effective range and its criterion of the transient stability margin based on the EEAC method werepresented. A new definition of the transient stability margin which is called the generalizedtransient stability margin was proposed. Differing from the traditional definition of the EEACmethod, this definition can cover wide range of state variables to nonlinear power system.The mathematical models of the generalized transient stability margin based on the EEACmethod were also derived. The validity of the proposed generalized transient stability marginin the dynamic security assessments was confirmed by the calculation analysis of a 59generator power system in the paper. |
