A Novel On-line Searching Approach of Key Transmission Line-set

摘要：

On-line searching for key transmission line-set is of great importance on real-time operation and cascading failures defense. This paper proposes a novel on-line searching approach of key transmission line-set. Firstly, parallel transmission line-set suffered greatly from the outages of lines is found out immediately according to real-time information of networks topology and power flow. Then key transmission line-set is searched by the calculation of proposed key indexes. And the index can effectively take current load level into account as well as the impact on the whole grid when line tripping. At last, the validity of proposed approach is verified by the calculation result of IEEE 39-bus system.
