摘要
为提高电力系统安全运行水平,结合以往电网脆弱线路识别方法,提出一种考虑潮流方向性的电气介数的电网脆弱线路识别方法,分析该方法利用发电转移分布因子计算方向电气介数,识别电网脆弱线路的过程,通过在IEEE39节点系统中的仿真算例及对比,验证了该方法的正确性和优越性。
To improve the safety operation level of power system, combining with the previous methods shortage which assume that the power only flow though the shortest paths between buses, this paper puts forward vulnerable lines in power system i- dentify method considering power flow directional electric betweenness. Using generation shift distribution factor calculate the directional electric betweenness to identify vulnerable lines;the simulation example in IEEE39 bus system and the comparison with previous research verify the validity and superiority of this method.
