针对关联输电断面极限功率计算方法缺乏、枚举组合计算量巨大且难以在线应用的问题,基于大规模分布式并行处理技术,提出了先计算静态极限功率,再计算暂态和动态极限功率的分步计算策略,以及分挡迭代的并行安全校核搜索策略。所述策略不仅对下一步极限功率计算的考核故障集进行了筛选,提高了极限功率搜索速度,而且给出了关联断面极限功率之间相互影响因子的计算方法,为调度运行控制提供了决策支持。南方电网的算例分析验证了所提出的方法的快速性和有效性。

There is a lack of limit power calculation method for the correlative transmission interfaces,and the high computational cost associated with enumerating combination makes it unsuitable for online applications.A fractional step calculation strategy is proposed based on the distributed parallel processing technology.This strategy firstly calculates the static limit power and then calculates the transient and dynamic limit power.A searching strategy of security check in parallel and iteration is proposed as well.The proposed strategy can be used to select the evaluated fault set of next limit power calculation and improve the searching speed of limit power.It can also be used to calculate the interacted influence factors of correlative transmission interface limit power,so as to provide the decision support for dispatching operation control.Case studies of China Southern Power Grid prove the rapidity and effectiveness of the proposed method.
