以潮流方程在给定运行点的局部仿射特性为基础，研究了常规潮流的灵敏度与计及发电机无功越限、有功经济调度等影响灵敏度计算精度的重要约束条件，得到约束灵敏度，建立了计及负荷的静态特性的潮流模型，并基于约束灵敏度指标判断薄弱节点，在求解过程中采用内点法（极坐标形式）的最优潮流计算，克服了常规灵敏度系数计算方法与实际情况不符的现状。

Based on the local affine characteristics at the given operating point by the flow equation,this paper examines the sensitivity of the conventional power tide and the constraint sensitivity obtained by taking into consideration of those imp-ortant containing conditions which affect the sensitivity accuracy such as the reactive power of the power generator and active economical scheduling, and then establishes the load flow model of static characteristics. And weak nodes are determined according to the constraint sensitivity index. The interior point method (polar coordinates)is used to calculate the OPF in the solution process so that the inconsistency of the conventional sensitivity coefficient calculation method with the actual condi-tion is overcome.
