不规则波下波浪能发电装置模型实验室入射波功率计算方法研究

CALCULATION METHOD OF INCIDENT WAVE POWER OF IRREGULAR WAVE FOR WAVE ENERGY CONVERSION MODEL SYSTEMS

在实验室测试波浪能发电装置转换效率时,入射波功率的计算方法是关键,特别是不规则波入射波功率的计算方法,国内外尚无统一标准,且不同方法的计算结果差别较大。在分析和比较国内外最常用的5种计算方法后,基于ITTC计算方法并结合中国国内的经验公式,建立根据不同谱型,以有效波高和谱峰周期为参数的室内测试入射波功率计算方法,并应用到实际的测试工作中,可更加科学与方便地计算不规则入射波功率,以期为国内波浪能发电装置室内测试方法的建立提供参考依据。

When calculating the conversion efficiency of wave energy conversion model systems,the calculation method of incident wave power is very important,especially for the calculation method of irregular incident wave power. After analyzing and comparing the five most commonly used calculation methods at home and abroad,based on the calculation method of ITTC and combined with domestic empirical formula, a new calculation method of the incident wave power with significant wave height and spectrum peak period as parameters was obtained according to the different spectrum type. It is more scientific and convenient to calculate the irregular incident wave power when applied in the actual test work,which provides a reference basis for establishing the lab test methods of wave energy power generation device.
