Impact of transmission tower-line interaction to the bulk power system during hurricane
Reliability Engineering & System Safety, 2020Abstract A Hurricane is a severe weather event that has caused massive blackouts in the United States. Previous studies about a hurricane's impact on the power system were mainly conducted through statistical analysis. However, there is limited research that reveals the physical law governing power outage and system-level performance. Therefore, this

The Response Analysis of Angle Tower Line System by Broken Lines
Applied Mechanics and Materials, 2015The suddenly break makes the tension of tight lines rapid realease. The tower system will be subject to impact,but the design specification considers the break load only by static load.Beacuse of the angle between the sides of the transmission lines and the span changes, In order to solve this problem this paper uses the finite element program ANYSY/LS-
