ABSTRACT = {In order to study the wind-induced vibration control effect of the viscous damper 
on the large-scale substation frame, this paper takes the large-scale 1000 kV substation 
frame of western Inner Mongolia as an example. The time-history sample of pulsating wind 
load is simulated by harmonic superposition method based on Matlab software. 6 kinds of 
viscous damper arrangement schemes have been designed, and SAP2000 finite element 
software is used for fine modeling and input wind speed time history load for nonlinear 
time history analysis. The displacement and acceleration of a typical node are the indicators 
of wind vibration control. The wind-induced vibration control effects of different schemes 
under different damping parameters have compared, and the damping parameters are 
analyzed for the optimal layout scheme. The results show that a viscous damper has 
installed in the lower layers of the substation; a viscous damper is placed between the 
ground column and the lattice beam. It is an integrated optimal solution. The wind-induced 
vibration control effect of the optimal scheme is sensitive to the viscous damper parameters, 
and the control effect does not increase linearly with the increase of the damping index and 
the damping coefficient. Corresponding to different damping indexes, the damping 
coefficient has a better range of values.},
