Problems solved by technology

[0009] Both of the above two calculation models have certain limitations, and are not suitable for the calculation of wave energy wave power density in the coastal waters of the China Sea. Therefore, it is necessary to establish an accurate calculation of the wave power density that only depends on the wave parameters and is suitable for the coastal waters of the China Sea. method

Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] Using the results of the wave field and wave power density of three small areas near the China Sea in the past 10 years simulated by the MASNUM wave numerical model, the data in 2012 were selected to form a modeling data set, and a wave suitable for the near-shore waters of the China Sea was established. Accurate parameterized calculation method of energy wave power density.

[0043] because Therefore the construct calculates P w The polynomial model for :

[0044] P w = Σ i = 1 n a i ( H s 2 T e ) ...

Abstract

The invention discloses an offshore area wave power density parameterization calculation method for the China Sea. The method includes the following steps that firstly, a wave power density polynomial model is established; then, the significant wave height, an energy period and the wave power density which correspond to multiple offshore areas are acquired from MASNUM wave numerical models of the offshore areas in a whole year of a certain year; the significant wave height, the energy period and the wave power density serve as parameters of the polynomial model and the wave power density polynomial model is fit; finally, the polynomial model is used for accurately evaluating offshore area wave energy resources. By the adoption of the method, the wave power density can be calculated through the parameters of waves.

Description

technical field [0001] The invention relates to a method for parameterized calculation of wave power density in near-coast sea areas of the China Sea. Background technique [0002] With the development of human society and economy, the demand for energy is increasing day by day. For any country on the earth, the reserves of conventional fossil energy such as oil, natural gas, and coal are limited. will quickly approach depletion; in addition, the carbon emissions of conventional fossil energy will lead to global warming. [0003] The shortage of conventional energy and the pollution of the climate are major problems that countries all over the world need to face, and they are also one of the main factors that hinder my country from building a maritime power. The development of new green energy has become an urgent need for economic and social development. Wave energy is an important marine renewable energy. It has the advantages of high density, wide distribution, inexhaus...
