Research on the Upper Constrained Damping Control System of UHV Suspended Converter Valve
The horizontal displacement of the converter valve is an important index for evaluating its seismic performance under earthquake. To reduce the displacement response of the valve during an earthquake
the upper restrainted damping control system
consisting of multiple inclined insulating tie rods and sprign damping nodes
is proposed in this paper. A computational model is set up based on the converter valve hall and converter valve tower of a ±800 kV UHV converter station.Long-period seismic waves are put
and the upper restraint seismic control system is optimized through parameter analysis. The calculation results show that under the optimized damping parameters the displacement response at the bottom of the valve is reduced by 48% in average. The upper constrained damping control system can effectively reduce the bottom displacement response of the converter valve under longperiod seismic waves.
