    摘要:

    海上光伏是一种新的能源利用方式和开发模式。为保证海上光伏电站安全运行,在场区外围布置消浪设施以减小海浪对场区结构影响是一种新探索。本研究以实际工程出发,对海上光伏区外围采用透空消浪板结构型式方案,采用波浪水槽模型试验,研究三种组合工况(50年一遇高潮位组合50年一遇波浪、50年一遇高潮位组合25年一遇波浪、25年一遇高潮位组合25年一遇波浪)下的消浪率和波浪力情况。研究结果表明:(1)三种工况下,波高Hs和H1%消浪率为11.9%和11.3%;7.0%和6.8%,6.7%和6.6%,消浪效果明显;(2)三种工况下,对于透空消浪板结构波浪力的单宽正向波浪力分别为36.88kN/m和35.64kN/m,23.89kN/m和23.29kN/m,19.25kN/m和18.64kN/m,消浪板结构安全性有效保障。本探究了空消浪板结构型式方案,为保证海上光伏发电工程结构安全性与经济性提供参考。

    Abstract:

    Offshore photovoltaic is a new energy utilization and development model. To ensure the safe operation of offshore photovoltaic power plants, it is a new exploration to arrange wave dissipation facilities around the site area to reduce the impact of waves on the site structure. From practical engineering, this study adopts a transparent wave dissipation plate structure scheme for the periphery of offshore photovoltaic areas. Wave tank model tests are conducted to study the wave dissipation rate and wave force under three combination conditions (50 year high tide level combination with 50 year high wave, 50 year high tide level combination with 25 year high wave, and 25 year high tide level combination with 25 year high tide wave). The research results show that: (1) under three working conditions, the wave height Hs and H1% wave dissipation rates are 11.9% and 11.3%; 7.0% and 6.8%, 6.7% and 6.6%, with significant wave dissipation effect; (2) Under three working conditions, the single width forward wave forces of the permeable wave dissipation plate structure are 36.88kN/m and 35.64kN/m, 23.89kN/m and 23.29kN/m, 19.25kN/m and 18.64kN/m, respectively, effectively ensuring the safety of the wave dissipation plate structure. This study explores the structural type scheme of air wave dissipation facilities, providing reference for ensuring the safety and economy of offshore photovoltaic power engineering structures.
