波能转换装置的非线性使它在不规则波中功率估算的频域方法产生了困难.事实上,气动式转换装置的性能主要与来波的周期和波高有关而与波形关系不大,因此我们有可能将不规则波看作一个挨一个的具有不同波参数的规则波(正弦波),而波能转换装置在这样一种波中的功率输出可认为是在一个挨一个的正弦波中之输出和.波能转换装置在规则波中的性能无论用理论方法还是用试验都是比较易于决定的,因此按上述途径即可估算出它在不规则波中的功率输出.本文先导出了南海海域的波高与周期的联合分布并由此导出了一个计算效率的简结表达式,进而讨论了几个在设计中感兴趣的问题,如最优设计条件的确定,频宽对不规则波中功率的影响及不规则的能流密度问题等.
The nonlinearity of the wave energy conversion device makes it difficult to estimate the frequency in the irregular wave frequency domain.In fact, the performance of the pneumatic conversion device is mainly related to the period and wave height of the incoming wave and not to the wave form, therefore It is possible to think of an irregular wave as a regular wave (a sine wave) with different wave parameters one by one, and the power output of the wave energy conversion means in such a wave can be considered as a sine wave one by one The output and the wave-transforming device in the regular wave performance of the theoretical method or test are relatively easy to determine, so the above way to estimate its irregular wave power output.This paper first derived The joint distribution of the wave height and period in the South China Sea has led to a concise expression of computational efficiency, and then discussed several issues of interest in the design, such as the determination of the optimal design conditions, the frequency of irregular wave The impact of medium power and irregular energy flow problems.
