Anti-seismic Performance Analysis on Tower of Suspension Ultra-high Voltage DC Filter Capacitor Bank

依据电力设施抗震设计规范,采用有限元分析软件,对特高压直流输电工程换流站直流场悬吊式特高压直流滤波电容器组塔架建立仿真模型,对模型进行动力计算分析,以计算结果为基础对电容器组塔架进行抗风动态载荷机械强度和地震强度的校核,确保设计的电容器组塔架满足抗震性能相关要求。

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.
