4 Frequently Asked Questions about “Wind power line tripping - RRR Renewable Projects (SA)”
Does longitudinal wind affect transmission lines?
In this study, only the along-wind effect is taken into account for the tower, as adopted in many previous works, , . As for the transmission lines, the influence of the longitudinal wind component can be ignored due to the restriction along the line direction.
Do wind-induced fatigue damage and anti-wind design optimization affect TTLS?
On the basis of the constructed distribution models, some researchers investigated the wind-induced fatigue damage and anti-wind design optimization of bridges, high-rise buildings and offshore wind turbines [18,,,, ]. As for TTLSs, only a few studies with consideration of such joint effects have been performed.
What is a wind-induced performance evaluation framework for transmission tower-line systems?
This paper proposes a comprehensive wind-induced performance evaluation framework for transmission tower-line systems (TTLSs) from both structural safety and normal operation dimensions, incorporating the joint effect of wind speed and direction, as well as the line orientation.
Do wind attack angle and line orientation affect TTLS failure probabilities?
Combining the continuous JPD function of wind speed and direction with the system fragility curves, the failure probabilities of a TTLS located in Weifang, China are evaluated from both structural safety and regular operation dimensions. Moreover, the effects of wind attack angle and line orientation are considered and discussed in detail.
Smart Tripping and Closing Strategy for Line-to-Line Un
The quasi-three-phase tripping strategy of the double-circuit transmission line can improve the reliability of power supply compared with the traditional automatic reclosing strategy, but
Wind-induced failure analysis of a transmission tower-line

Research on the Cascading Tripping Risk of Wind Turbine
Through the research on the cascading tripping risk of wind turbine generators caused by transient overvoltage and its countermeasures, we find that this problem is very serious.
An Intelligent Tripping-and-Reclosing Strategy for Grounding
Finally, the new tripping and closing strategy are combined to form an intelligent tripping-and-reclosing strategy for grounding faults on double-circuit wind power outgoing lines.
