| 摘 要： | 为快速消除线路过载避免发生连锁故障，提出一种基于潮流追踪和功率灵敏度的线路过载紧急控制策略。首先用潮流追踪法确定控制节点组，并结合发电机的调节速率计算出控制节点组的调整量。然后用功率灵敏度法判断控制节点组的功率调整方向。最后采用反向等量调整法对控制节点组进行相应的控制，通过IEEE39、IEEE118节点系统验证了潮流追踪和功率灵敏度组合方法的优越性和有效性。

| Abstract: | In order to eliminate line overload quickly and avoid chain failures, an emergency control strategy for line overload based on power flow tracing and power sensitivity is proposed. Firstly, the power flow tracing method is used to determine the control node group, and the adjustment amount of the control node group is calculated based on the adjustment rate of the generator. Then, the power sensitivity method is used to judge the power adjustment direction of the control node group. Finally, the corresponding control of the control node group is carried out by the reverse equal adjustment method. The superiority and effectiveness of the combined method of power flow tracing and power sensitivity are verified by IEEE39 and IEEE118 node systems. |
