Random vibration analysis of an offshore flexible direct current converter valve

With the rapid development of direct-current grid technology and construction, flexible transmission has been widely used in many aspects, such as long-distance large-capacity power transmissions, offshore platforms island supplies. The direct current converter valve will encounter a variety unfavorable loads during marine transportation long-term operation on sea. safety requirements are higher result. Based structural characteristics valve, is calculated by finite element method. Under two working conditions sea, this paper carries out modal analysis random vibration tower respectively. This gives position force from calculation results, provides reference for design selection to meet needs station’s construction.
