| 为海岛供电，是波浪能开发利用技术的重要应用领域。在海岛周边波浪能资源开发利用之前，需对波浪能资源进行精细化勘查，并在此基础上准确分析掌握工程实施海域的波浪能资源特征，以便开展有针对性工程设计。本文以威海褚岛北部海域为研究目标，结合对历史数据和水动力理论分析，制定精细化勘查方案，并通过代表性验证试验，对方案进行修正，再应用修正后的方案对目标海域进行长期观测。该方法改进了传统的波浪观测方法，更适用于小区域波浪要素的精细化观测，且在保证观测质量的前提下，有效降低了观测成本。另一方面，针对波向四季变化明显，且海岛周边波浪受岛岸线反射和绕射影响且地形变化剧烈的特点，本文利用改进的SWAN（simulating waves nearshore）数值模型计算目标海域波浪能资源，并结合统计学方法，研究波浪能量随波向分布特征的计算分析方法，得出褚岛周边海域全年波浪能量随波向的分布特征。 |

| Abstract: |
| Power supply for islands is an important application field of wave energy development and utilization technology. Before the development and utilization of the wave energy resources around the island, it is necessary to conduct a detailed investigation of the wave energy resources, based on which the characteristics of the wave energy resources in the sea area of the project implementation can be accurately analyzed to carry out targeted engineering design. In this study, the waters north of the Chudao Island in Weihai, Shandong Peninsula, East China was taken as the research objective, and historical data and hydrodynamic theoretical analysis were combined, a refined survey plan was formulated, and the plan was verified and tuned through representative tests, and then the revised plan was applied to the target sea area for long-term observation. This method improved the traditional wave observation method, and is more suitable for the refined observation of wave elements in small areas. On the premise of ensuring the quality of observation, the cost of observation was effectively reduced. On the other hand, because wave direction changes significantly in season and the waves around the island are affected by the reflection and diffraction of the island shape and the terrain, an improved SWAN numerical model was used to calculate the wave energy resources in combination with statistical methods. By studying the calculation and analysis method of wave energy distribution with wave direction, the distribution characteristics of wave energy with wave direction in the sea area around Chudao Island were obtained. |
