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 was 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]

[0045] In order to obtain the coefficient a of the polynomial calculation method by polynomial fitting i and C, using the data simulated by the MASNUM model of 3 small areas in the China Sea (nearshore shallow water area) in 2012 to construct a modeling dataset. When constructing a modeling dataset, select 3 small areas and 4 in 2012 The season represents the data of the month (...

Abstract

The invention discloses a method for parameterized calculation of wave power density in coastal waters of the China Sea, which includes the following steps: firstly, constructing a polynomial model of wave power density; Obtain the corresponding significant wave height, energy period and wave power density in several nearshore sea areas from the MASNUM wave numerical model; use the significant wave height, energy period and wave power density as parameters of the polynomial model to fit the polynomial model of the outgoing wave power density; Finally, the polynomial model is used to realize the accurate assessment of the wave energy resources in the coastal waters. The invention can calculate the wave power density through the parameters of ocean 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...
