摘要
将电路理论中计算灵敏度的增量网络法推广到电力网络中，提出了一种基于交流潮流模型的灵敏度分析方法——改进的增量网络法．该法能方便快捷地求出系统变量对所有线路（支路）参数的灵敏度。
In this paper, the incremental network approach for sensitivity analysis in circuit theory is extended to power network. A new method of sensitivity analysis based on the model of alternating power flow——the modified incremental network approach is suggested. The sensitivity data of the variables of system vs . the line (branch) parameters can be calculated easily and quickly. This method is valuable in transmission planning and other fields.
