Problems solved by technology

However, due to the different settings of the observation instruments and the large changes in climate and wind conditions in various places, there are great differences in the data format of wind measurement data, which greatly increases the complexity of wind energy resource assessment. At the same time, the general wind resource assessment system is

Embodiment 1

[0025] see figure 1 As shown, it is a schematic flow chart of the wind resource assessment method of the embodiment of the present invention. Such as figure 1 As shown, the wind resource assessment method in this embodiment includes steps:

[0026] Step S101: Determine whether the data format of the input original wind measurement data is the output format of the NRG wind measurement equipment, if not, proceed to step S102, and if so, proceed to step S103, because the original wind measurement data mostly comes from the NRG wind measurement equipment At the same time, the wind measurement data obtained by NRG wind measurement equipment contains header files, which can be identified through its header files. This step is equivalent to opening a green channel for the original wind measurement data of NRG wind measurement equipment. If the judgment result is NRG measurement wind equipment output format, the original wind measurement data can be directly exported according to it...

Embodiment 2

[0054] According to the above-mentioned wind resource assessment method of the present invention, the present invention also provides a wind resource assessment system, and the embodiments of the wind resource assessment system of the present invention will be described in detail below. The system is based on the C# language and component development technology of the .NET framework. The component technology-oriented organizational structure provides good scalability of the system, allowing the system to easily combine and split its functional modules.

[0055] figure 2 Shown in the structure schematic diagram of the embodiment of the wind resource assessment system of the present invention, the wind resource assessment system of this example includes judgment module 201, raw data management module 202, data inspection and correction module 203, wind condition parameter analysis module 204, fuzzy matrix Establishment module 205, wind resource classification module 206, wherei...

Abstract

The invention relates to a wind resource assessment method and a wind resource assessment system. The wind resource assessment method include: judging whether a format of original input wind measuring data is an NRC (new radiance group) output format of a wind measuring device or not, judging whether the format of the original input wind measuring data is matched with a preset data format or not, taking corresponding actions according to the judging result to obtain various parameters required for assessing wind energy resources; acquiring each assessment factor and corresponding standard assessment information of each assessment factor, and establishing a fuzzy relation matrix and an assessment factor weight matrix according to the assessment factors, the corresponding standard assessment information of each assessment factor and the parameters required for assessing wind energy resources; obtaining a wind resource grade assessment result via fuzzy variation according to the fuzzy relation matrix and the assessment factor weight matrix. Since the wind resource assessment method does not direct at a specific data format, convenience of the wind resource assessment is improved. Since the wind resource grade is assessed according to the principle of fuzzy mathematics, rationality and scientificity of the wind resource grading are improved.

Description

technical field [0001] The invention relates to the field of wind data monitoring of wind farms, in particular to a wind resource assessment method and a wind resource assessment system. Background technique [0002] Wind power uses natural wind as the driving force, and the output power of wind farms depends to a large extent on the characteristics of wind energy resources in the wind power development area. Real-time assessment of the distribution of wind resources in the wind power planning area, a comprehensive understanding of the distribution and characteristics of wind energy resources, mastering the characteristics of wind energy, and The planning, construction and operation of the power grid are of great significance. [0003] Wind farm wind data analysis, verification, and wind energy resource assessment are important basic tasks in the process of wind farm development and design, especially the quality inspection of massive wind data often determines whether the w...
