Problems solved by technology

[0003] At present, atmospheric stability is an important aspect that affects the accuracy of wind resource assessment. In the existing methods for determining wind resources, the atmosphere is usually directly assumed to be neutral, and the wind farm is assumed to have uniform atmospheric stability, which is easy. The problem that caused the simulation modeling to deviate from the actual situation needs to be improved urgently

Embodiment Construction

[0037] Various example embodiments will now be described more fully with reference to the accompanying drawings, in which some example embodiments are shown.

[0038] Refer below Figure 1 to Figure 4 A method and apparatus for determining wind resources according to embodiments of the present invention are described.

[0039] figure 1 A flowchart showing a method of determining wind resources according to an embodiment of the present invention.

[0040] In step S10, the atmospheric stability index of the target area is determined.

[0041] Here, the atmospheric stability index is an atmospheric stability index that best characterizes changes in the atmospheric stability of the wind farm.

[0042] As an example, the atmospheric stability index may include: Monin-Obukhov Length (MOL) and potential temperature gradient, but the present invention is not limited thereto.

[0043] It should be understood that as the actual situation of the wind farm changes, the atmospheric sta...

Abstract

The invention provides a method and a device for determining wind resources. The method for determining the wind resources comprises the following steps: determining an atmospheric stability index ofa target area; obtaining a plurality of atmospheric stability index sequences corresponding to a plurality of coordinate points in the target area, wherein each sequence comprises a plurality of atmospheric stability index values corresponding to the corresponding coordinate points within a predetermined period of time; determining available atmospheric stability index values in the plurality of atmospheric stability index sequences; dividing atmospheric stability levels based on the available atmospheric stability index values; and determining wind resources of the target area based on the divided atmospheric stability level. According to the method and the device for determining the wind resource, the wind power plant is divided into different regions through the accurately divided atmospheric stability level, and wind power plant wind resource assessment is carried out for different regions, so that the accuracy of wind power plant wind resource assessment can be effectively improved.

Description

technical field [0001] The present invention generally relates to the technical field of wind power, and more specifically relates to a method and device for determining wind resources. Background technique [0002] Before the construction of wind farms, it is necessary to demonstrate and analyze the feasibility of wind farm construction. As the basis for analyzing the feasibility of wind farm construction, wind resource assessment is an important prerequisite for vigorously developing wind power generation. [0003] At present, atmospheric stability is an important aspect that affects the accuracy of wind resource assessment. In the existing methods for determining wind resources, the atmosphere is usually directly assumed to be neutral, and the wind farm is assumed to have uniform atmospheric stability, which is easy. The problems that cause the simulation modeling to deviate from the actual situation need to be improved urgently. Contents of the invention [0004] The...
