Abstract Two common techniques in determining surface wave power include a full wave spectrum integration and a representative wave approach. Under the concept of spectral wave parameterization, a new estimation formula is introduced in this study to capitalize the advantages of both the numerical method and the closed-form solution. The formula was verified using synthetic wave data and its applicable condition is recommended to be in the upper-intermediate to deep water environment. Validation against reliable field wave data showed that the new solution can outperform the representative wave approach by allowing higher estimation performance around 5%–15% on average. The new formula was applied for a practical estimation of wave power in Thailand. While the resulting wave power was found to be relatively low around 0.3 to 1.5 kW/m, the utility of the new solution can be warranted according to its consistency with the full numerical technique. This encouraging outcome is achievable as the deviation of the resulting estimates is limited and symmetric about a neutral mean. In summary, the superiority of the new analytical formula can be attributed to its dependable replication of typical random wave field and its adaptability to irregular wave energy distribution in the nature.

在泰国沿海应用的表面波功率估计解析公式

摘要 确定表面波功率的两种常用技术包括全波谱积分法和代表性波法。在谱波参数化的概念下，本研究引入了一种新的估计公式，以利用数值方法和封闭形式解的优点。该公式通过合成波浪数据进行验证，建议其适用条件为中上至深水环境。对可靠的场波数据的验证表明，新的解决方案可以通过允许更高的估计性能（平均约 5%–15%）优于代表性波方法。新公式已应用于泰国波浪能的实际估算。虽然发现由此产生的波浪功率相对较低，约为 0.3 至 1.5 kW/m，根据新解决方案与完整数值技术的一致性，可以保证新解决方案的实用性。这个令人鼓舞的结果是可以实现的，因为结果估计的偏差是有限的，并且关于中性平均值对称。综上所述，新解析公式的优越性在于其对典型随机波场的可靠复制和对自然界不规则波能量分布的适应性。
