A method and system for route planning of wind farm collector lines

Abstract

The present invention provides a method for planning the path of a wind farm collector circuit, which includes the following steps: (1) grouping fans according to the location of the fan, the location of the substation, and the direction of the outgoing line, and each group of fans forms a collector circuit unit; (2) According to the wind turbine hub height and blade length information, draw the safe area of ​​the wind turbine to avoid collision between the line and the blades of the wind turbine and other equipment; (3) According to the extension grouping scheme and the two-dimensional map of the wind farm, manually select the path to obtain multiple alternative paths , connect all the fans in this group to the incoming line side of the substation; (4) According to the alternative path, go to the site for survey and measurement, then carry out wiring and tower arrangement, line foundation design, and draw construction drawings. It also provides the corresponding path planning system for wind farm collector lines, which improves the accuracy of engineering design, reduces engineering costs, improves design efficiency, and makes the design work more flexible and intelligent, and the collector lines are least affected by extreme weather conditions .

Description

technical field [0001] The invention belongs to the technical field of engineering planning and design of wind farms, and in particular relates to a path design for overhead collector lines of wind farms. Background technique [0002] Wind power generation is the clean energy with the most economic development value among renewable energy sources. The development and utilization of wind resources is one of the important measures for my country's energy development strategy and power structure adjustment. Wind energy is not only a green and environmentally friendly renewable energy, but also an important energy source with mature technology and sustainable development for industrial development. The large-scale development of wind power generation is the most realistic strategic choice to solve my country's energy and power shortages. [0003] Wind farm project planning and design mainly includes wind turbine site selection, substation design (including site selection), on-si...

Problems solved by technology

[0012] In the prior art, there is no mature design method for path planning of overhead collector lines, such as the Chinese patent application CN107357965A, which is usually an attempt by designers to plan multiple paths for specific projects based on experience and in combination with the above design rules, within a limited time and Selecting a relatively optimal collection line path under the cost, resulting in low accuracy of wind farm collection line engineering design, often due to lack of experience of designers and insufficient analysis of meteorological data, resulting in increased project costs, in the early stage of wind farm In the scheme comparison, the human and material costs and time consumption of wind power line design are high, the design efficiency of wind power line engineering is low, the design of wind power project collection is not flexible and intelligent, and the risk factor caused by weather and other factors is high
