Simulation Analysis of Seismic Response and Damping Control of Supported VSC-DC Converter Valve
摘要
Abstract
The supported VSC DC converter valve is one of the key equipment of VSC-HVDC transmission technolo-gy with high construction cost and important function.It is of great significance to ensure the stable operation of VSC-DC valve in various situations and is necessary to carry out research on its seismic safety.For improving the seismic performance of the supported converter valve,the finite element numerical simulation analysis is adopted in this pa-per to simulate the seismic response of the valve tower under the condition of applying different pre-stresses to the di-agonal insulator,and a new type of vibration damping method-diagonal insulator-ring spring damper is proposed,which is to install ring-spring damper at the end of the original diagonal insulator.The seismic response of the valve tower with different prestressed tilt insulators and the installation of combined damper is compared.The result shows that in case of installation of the combined damper,the top displacement response of the valve tower and the root stress of the equipment are greatly reduced,and the dual control of the root stress and top displacement of the equip-ment can be achieved,which is of higher value for engineering applications.Considering the engineering reality,re-placing only the outer part of the prestressed diagonal insulators can also achieve better displacement and stress con-trol,reduce the cost while simplifying the construction process of the existing valve tower vibration isolation mea-sures,and has higher engineering application value.关键词
