Wind farm planning method in flat area

Abstract

The invention provides a wind field planning method for a flat region, belonging to the technical field of wind field planning. The method comprises the steps of: determining a research wind field and a reference wind field in the flat region, and determining the angle and the distance between the research wind field and the reference wind field, wherein the angle is consistent and the distance is variable; calculating relative values of influence of the reference wind field on the wake flow of the research wind field in different distances; and fitting the relative values with the distances by utilizing a linear relation, and determining the final distance between the reference wind field and the research wind field according to the standard wake flow value. According to the method, the technical problem that how to plan the wind field more reasonably to obtain optimum generated power is solved.

Description

technical field [0001] The invention relates to the technical field of wind field planning, in particular to a wind field planning method in a flat area. Background technique [0002] Wake value: refers to the amount of power generation of the wind power generation unit that is reduced due to the influence of the wind power generation units and the terrain and landform. It is usually measured as a percentage of the total power generation. For a wind farm, it generally refers to the loss The ratio of the total electricity to the total power generation. [0003] Flat area: Refers to the area where there are no obvious protruding features and the slope of the terrain is less than 8% within the entire area. [0004] Wind field planning method: refers to how to arrange the wind fields in the region so that the impact is small, and the waste of land is minimized, and the method of increasing the scale of the wind field. [0005] At present, for the planning of wind farms in a re...

Problems solved by technology

However, the distance of the isolation zone between wind farms is not clearly stipulated in the relevant laws and regulations of the country and industry regulations. It is often based on the experience of engineering personnel. Some distances are 500 meters, and some distances are 2000 meters, which is very random.

If the set distance is small, the mutual wake influence value is too large, which will affect the power generation of the wind farm, but if the distance is too large, the number of set wind farms will be reduced in a limited area, Then the total installed capacity will decrease, which will also affect the power generation of wind farms

However, only relying on the experience of engineering personnel to set up the isolation zone of the wind field cannot accurately consider the influence of the wake value and the size of the installed capacity, so that the planning of the wind field cannot be reasonably given to obtain the best wind power in a given area. power generation
