In this paper

the simulation model of tower of suspension ultra-high voltage DC filter capacitor bank at converter station of ultra-high voltage DC transmission project is set up in accordance with anti-seismic specification of electrical equipment and by way of adopting definite element analysis software.The dynamic calculation analysis for the model is made and anti-wind dynamic load mechanical strength and the seismic strength for the capacitor bank tower based on calculation result is checked so to assure that the designed capacitor bank tower can meet related anti-seismic requirements.
