Wind-Induced Coupling Vibration Effects of High-Voltage Transmission Tower-Line Systems

Table 8

Comparison of the dynamic analysis results of the displacement at the top of the transmission tower for the single tower and the tower-line system under a wind speed of  m/s.

Node number	Maximum value			Average			Root mean square
	TL	ST	TL/ST	TL	ST	TL/ST	TL	ST	TL/ST
-direction displacement at the top of the tower (m)
727	0.26	0.05	5.2	0.20	0.03	6.7	0.01	0.004	2.5
660	0.20	0.04	5.0	0.16	0.03	5.3	0.01	0.003	3.3
-direction displacement at the top of the tower (m)
727	0.07	0.0008	87.5	0.02	0.0004	50	0.02	0.0001	200
660	0.04	0.0008	50	0.01	0.0005	20	0.01	0.0001	100

Note. In the table, TL represents the response value of the tower in the tower-line system, and ST represents the response value of the corresponding single tower.
