Embodiment Construction
[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0034] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for both fixing and circuit communication.
[0035] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", ...

The present invention provides a method for constructing an offshore wind energy data database and an offshore wind energy power generation database. The method for constructing an offshore wind energy data database includes the following steps: S1: Obtain the boundary conditions of the mesoscale meteorological numerical model, and the boundary conditions include offshore Meteorological variable information on the boundary of the wind field; S2: Decompose the meteorological variable information by using space-time separation method; S3: Use the mesoscale meteorological numerical model to reduce the dimension of the boundary conditions to obtain high-precision modal weather S4: further obtain the high-precision actual weather field, and establish a high-precision regional three-dimensional wind field database. The 30-year long-term high-precision three-dimensional wind field that reflects both time and space changes can be obtained, so as to establish a high-precision wind energy data and power generation database in China's coastal waters.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method for constructing an offshore wind energy data database and an offshore wind energy generation database. Background technique [0002] Wind energy, as a clean, renewable and easily accessible energy source, is currently one of the most promising renewable energy sources. Due to the rich resources of offshore wind energy, the visual and noise pollution caused by its development method is less than that of land wind energy, so it has developed rapidly in recent years. However, compared with land wind energy, offshore wind energy faces a more complicated situation. The biggest obstacle faced in the whole wind energy plan is the accuracy and reliability of wind energy data. Observation sites such as offshore buoys and wind towers are very rare, and usually only have short-term observation data, which cannot meet the needs of wind energy assessment. Therefore,...
