摘要
针对前人研究中的不足,即没有提出分区内部输电断面以及非割集形式的基于热稳定约束的输电断面的搜索方法,将整个省网在地理分区的基础上对交界厂站进行优化,分别对分区间和分区内部进行研究,仅考虑线路和主变压器的热稳定约束,运用图论的相关知识,根据潮流转移的特征,进行输电断面的搜索。算例表明了所提算法的有效性。
Aiming at the deficiency of previous studies, that is, the search method for transmission section in the zone and transmission section of non - cut set form, so the border stations are optimized on the basis of geographical divisions. The ther-mal stability constraints of lines and main transformer are only considered and the graph theory is used to search transmission section according the features of power flow transfer. Examples show the effectiveness of the proposed method.
