近海风电场设计潮位确定初步探讨

在近海风电场工程设计中,设计潮位是一项重要的水文参数。由于风电场工程区常缺乏长期验潮资料,需利用附近具有长期实测资料的海洋水文测站作为参证站,采用多种方法计算设计潮位。文章在总结众多研究成果的基础上,将潮汐性质相似性判断的定量指标及标准应用到近海风电场潮汐相似性检验中,采用短期同步差比法和相关分析法计算近海风电场的设计高、低水位。计算结果表明,笔者推荐的方法是合理、可行的。

Study on Determination of Design Tidal Level for Offshore Wind Farms

in design of offshore wind farms, the design tidal level is one important hydrological parameter. As data in a long term to verify the tide in the wind farm region is lack, the ocean hydrological stations with the long-term measured data near the farm are considered the reference ones and a couple of methods are applied to calculate the design tidal level. In this paper, the quantative indicators and stand- ards for determination of the tidal property comparability are utilized in verification of the tidal comparability of the offshore wind farms based on various study results. The short-term synchronizing differential method and relevant analyzing methods are applied to calculate the design maximum and minimum tidal levels of the offshore wind farms. The calculation results prove that the recommended methods are reasonable and feasible.
