中文摘要：
利用几何学知识推导出了确定电力系统实用动态安全域（PDSR）临界超平面的截距法.该方法首先根据决策空间中PDSR的二维断面上临界线与决策变量上、下限的截距计算出所有超平面系数之间的比例关系,然后利用这些比例关系和一个由数值仿真法搜索出的临界稳定点确定临界超平面.对新英格兰系统的测试结果表明了该方法的有效性和快速性.此外,文中还分析了该方法的联想功能,利用该功能可以由一个已知故障下的PDSR临界超平面计算出另一个故障下的PDSR临界超平面.
英文摘要：
An intercept method to determine critical hyper-planes of practical dynamic security region （PDSR） of power system is developed by use of knowledge of geometry. According to the intercepts where the critical line intersects the decisive variables＇ maximum and minimum values in the two-dimension space of PDSR, the proportional relationships among all of critical hyper-planes＇ coefficients are derived. The critical hyper-planes can be determined based on these proportional relationships and a critical operating point obtained by numerical simulation. Studies on New England system indicate that the proposed method is effective and fast. Moreover, the association function of the method is analyzed, by which the critical hyper-planes of PDSR corresponding to one fault can be calculated according to those of PDSR corresponding to another known fault.
