摘要
能量函数法是分析电力系统暂态稳定问题的一个非常有效的方法。本文首次推导了严格的单机能量函数灵敏度分析的全套解析公式。然后,利用能量函数法中已有的假设条件,提出了一套快速算法,使在运行能量函数法的同时,只需增加极少的计算量,便可进行灵敏度分析和快速计算系统暂态稳定极限。
Energy function sensitivity analysis is a very useful measure for transient stability preventive control. In this paper, strict individual machine energy function analytical sensitivity is derived. Based on the well-known assumption used in energy function method, a very fast sensitivity analysis algorithm is proposed to avoid the computation of trajectory sensitivity after the fault clearing. Therefore, little additional computation is needed in the proposed sensitivity analysis for assessing the transient stability limits.
