如东海域某风电场设计风速和波浪研究

Design wind speed and design wave of a wind farm in Rudong sea area

风、浪是影响海上风电场风电支撑结构安全的重要因素,为了确定如东某海域海上风电场设计波浪,采用WRF大气模式模拟热带风暴过程并联合CCMP风场数据集作为驱动风场,利用SWAN模型对如东风电场海域近20 a的波浪过程进行了模拟,获得了不同重现期风速和波浪要素。结果表明,WRF模拟热带风暴结果和CCMP风场联合可以获得更为准确的风场,也可以获得更合理的波浪计算结果。

Wind and waves are important factors affecting the safety of the wind power supporting structure of offshore wind farms.In order to determine the design waves of an offshore wind farm in Rudong,the atmospheric model WRF were adopted to simulate the process of tropical storm and joint CCMP wind field data set as a drive wind field,by which the SWAN model was used to simulate the wave process in the sea area of Rudong wind farm in the past 20 years.The wind speed and wave elements in different return periods were obtained.The results show that the combination of WRF simulated tropical storm results and CCMP wind field can obtain more accurate wind field and more reasonable calculated wave results.
