Description

A wind turbine arrangement method for plain areas based on a Web application system TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy wind power generation, and particularly relates to a wind turbine arrangement method for plain areas based on a Web application system. BACKGROUND

[0002] With the increasing demand for renewable energy worldwide, wind energy as a clean and sustainable energy form has attracted widespread attention for its development and utilization. In particular, in plain areas, due to the relatively flat terrain, the construction and maintenance costs of wind farms are relatively low, so it has become an important area for wind energy development. However, the wind turbine arrangement of wind farms in plain areas is a complex engineering problem involving wind energy resource assessment, land use planning, environmental impact assessment, economic benefit analysis and other aspects. Traditional wind turbine arrangement methods rely on professional software tools and expert experience, and these methods often require a lot of repeated calculations and analyses, which are time-consuming and inefficient. In addition, with the development of wind power technology and the expansion of wind farm scale, traditional wind turbine arrangement methods are increasingly insufficient in data processing capacity, scheme optimization and decision support.

[0003] The present application provides a wind turbine arrangement method for plain areas based on a Web application system. This method uses Web technology to integrate various calculations, analyses and optimization tasks in the wind turbine arrangement process into a unified online platform. Moreover, the Web application system can automatically collect and integrate wind energy resource data, terrain data, land use information and other data from different sources, and simulate the wind field characteristics of the plain area in real time, including wind speed distribution, wind direction changes and other aspects, providing a scientific basis for wind turbine arrangement. This method can significantly improve the efficiency and quality of wind turbine arrangement and reduce project costs. In addition, the flexibility and scalability of this method provide strong support for the future development and application of wind power technology. SUMMARY

[0004] To solve the above problems, the present application provides a wind turbine arrangement method for plain areas based on a Web application system.

[0005] The specific technical solution is as follows: a wind turbine arrangement method for plain areas based on a Web application system, comprising the following steps:

[0006] (1) Determine the dominant wind direction: access the meteorological database through the Web application system, analyze the historical wind speed and wind direction data, generate the wind direction rose diagram and the wind power density rose diagram, identify the prevailing wind direction and the annual average wind speed, and determine the dominant wind direction;

[0007] (2) Parameter setting: input the wind turbine model parameters into the system and set the row and column spacing of the wind turbine arrangement;

[0008] (3) Determine the first position of the wind turbine: calculate the normal vector of the wind direction (y=kx+b), and then calculate the intersection point of the normal vector and the target area to obtain the spatial coordinates (X, Y, Z) of the intersection point. The coordinate position of the intersection point is the real-time position of the first wind turbine;

[0009] (4) Quincunx arrangement: according to the position of the intersection point in the target area, perform regular translation, and calculate the actual coordinates (X and Y) according to the selected arrangement method, such as row spacing 6D and column spacing 3D, to obtain the actual difference distance of X and Y. The geographical position of the next wind turbine is obtained, and the arrangement of the first row of wind turbines is completed. Then, the second row of wind turbines is arranged. The second row of wind turbines is affected by the wake of the previous column of wind turbines, so the cross arrangement is adopted (the current column of wind turbine points is arranged in the wind direction with a radius of = as the intersection point of the grid (6x3), and the intersection point is the point of the next column of the cross arrangement. Repeat the above steps to delete the repeated points) to reduce the influence of the wake. The distance between the second row position and the normal vector is column spacing x D x N, where N is the number of columns and D is the diameter of the wind turbine impeller.

[0010] (5) Complete the wind turbine arrangement in the entire area: calculate all the coordinate information of the wind turbines in the area according to the method of step (4), and arrange the wind turbines according to the coordinate information.

[0011] Further, the input wind turbine model parameters include the rated power, impeller diameter, cut-in wind speed, and cut-out wind speed of the wind turbine.

[0012] The beneficial effects of the present application are as follows:

[0013] (1) The wind turbine arrangement method based on the Web application system provided by the present application utilizes computer algorithms and GIS technology to quickly identify areas with high wind speed and stable wind flow, determine the best arrangement position for wind turbine arrangement, maximize the use of terrain and wind resources, and improve wind power generation efficiency.

[0014] (2) The present application utilizes automatic algorithms to quickly generate a recommended scheme for wind turbine arrangement, and considers the optimal spacing and direction between wind turbines to reduce mutual shielding and influence between wind turbines and improve the overall performance of the wind turbine combination.

[0015] (3) The Web application system used in the present application has the advantages of flexibility and visualization, and users can set parameters and optimize adjustments as needed to flexibly generate different wind turbine arrangement schemes. At the same time, the system usually provides visual display functions, allowing users to intuitively understand the layout results and perform feasibility evaluation.
