摘要

为了评估某±800 kV特高压直流换流站阀厅及其内部回路的地震易损性，文中通过建立换流阀厅回路有限元模型，进行增量动力时程分析，根据计算结果采用非线性最小二乘回归方法得到阀厅回路在不同破坏模式下的地震易损性曲线。结果表明：在地震作用下，特高压穿墙套管根部应力与换流阀塔悬吊绝缘子拉力峰值响应较大，换流阀塔底部位移接近限值；其中，悬吊绝缘子的地震易损性最高，穿墙套管根部地震易损性次之，换流阀塔因位移过大而破坏的概率较低。在对换流阀厅进行抗震设计时，应优先采用更高强度的悬吊绝缘子；穿墙套管是换流阀厅回路中的重要设备，应在其根部采取抗震加固措施；阀塔底层位移过大会造成与之耦联的管母或连接金具局部应力过大或者不满足最小空气净距的情况，应采取相应措施减小其底部位移。

Abstract

For assessing the seismic vulnerability of the valve hall in a ±800 kV UHVDC converter station and its internal circuit

the incremental dynamic time-history analysis is performed by setting up a finite element model of the converter valve hall circuit. According to the calculation result

the nonlinear least squares regression method is used to obtain the seismic vulnerability curves of the valve hall circuit under different failure modes. The results show that under the seismic action

root stress of the UHVDC wall bushing and the peak response of the suspension insulator tension in the converter valve tower are significant

while the displacement at the bottom of the converter valve tower approaches the allowable limit. The suspension insulator has the highest seismic vulnerability

followed by the root section of wall bushing

and the converter valve tower has a lower probability of damage due to excessive displacement. In case of seismic design of the converter valve hall

higher-strength suspension insulator shall be given priority. Wall bushings are important equipment in the converter valve hall circuit

and seismic reinforcement measures shall be taken at its root section.Excessive displacement at the bottom of valve tower may lead to excessive partial overstress in connected busbars or fittings

or result in non-compliance with the minimum air clearance resuiements. Corresponding measures shall be implemented to reduce displacement at the bottom of the valve tower.
