摘要
海上换流阀在运行期间的安全性关系到海洋风电的有效输送。为研究支撑式海上换流阀塔运行期间的结构响应,依据某工程中的海上柔直换流阀建立有限元模型,通过模态分析和时程分析,研究了换流阀塔的自身振动特性和在环境荷载作用下的动力响应。结果表明,换流阀塔弱轴振动方向为连接前后两个单塔的方向,外荷载作用下将在此方向产生较大动力响应,换流阀塔运行期间的最大位移和最大应力均满足安全要求。
The safety of offshore direct current converter valve during operation is related to the effective transmis⁃sion of the offshore wind power.In order to research on the structure response of the support⁃type offshore direct cur⁃rent converter valve tower during operation,a finite element model is set up in accordance with the offshore flexible direct current converter valve of a certain project.The vibration characteristics of the converter valve tower itself and its dynamic response under the action of environment loads are studied through modal analysis and time history anal⁃ysis.The results show that the vibration direction of weak axis of the converter valve tower is the direction of connect⁃ing two single front and rear towers.Under the action of external load,the larger dynamic response is generated in that direction.The maximum displacement and stress of the converter valve tower meet the safety requirement during operation.
