Wind power plant power collection line route planning method and system

Abstract

The invention provides a wind power plant power collection line route planning method. The method comprises the steps that (1) fan grouping is performed according to fan point locations, a substationposition and an outgoing line direction, and each group of fans forms a power collection line unit; (2) a fan safe region is drawn according to fan hub height and blade length information, and collision between a line and fan blades and other equipment is avoided; (3) according to a fan grouping scheme and a wind power plant two-dimensional diagram, route selection is performed manually, multiplealternative routes are obtained, and all fans in the same group are connected to a substation incoming side; and (4) according to the alternative routes, survey and measurement are performed on a spot, and then wire tower arrangement, line basic design and construction drawing production are performed. The invention furthermore provides a corresponding wind power plant power collection line routeplanning system. Through the system, the precision of engineering design is improved, engineering cost is lowered, design efficiency is improved, design work is more flexible and intelligent, and theinfluence of an extreme climate condition on the power collection line is minimum.

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
