Mountain land photovoltaic power station arrangement method

Abstract

The invention relates to a power station arrangement method, in particular to a mountain land photovoltaic power station arrangement method. According to the mountain land photovoltaic power station arrangement method, Google globe software and ArcGIS software are used for completing sloping field modeling, a TIN topographic map is generated, and therefore manpower consumption and material resource consumption are reduced; analogy computation is carried out on the TIN topographic map of a mountain land area through sunlight analysis software so that the generating-capacity computing accuracy can be improved; the mountain land trend is sufficiently depended, photovoltaic arrays are arranged along a mountain, the amount of steel used in supports and the occupied area are reduced, the construction difficulty is reduced, a large amount of capital is saved, and influences on the generating capacity are not serious; shadow contour analysis is carried out on the TIN topographic map of the mountain land area through the sunlight analysis software, locating points of the arrays are determined, and the effective method which is rapid and convenient to use is provided for northern hemisphere sloping field photovoltaic arrays.

Description

technical field [0001] The invention relates to a method for arranging a power station, in particular to a method for arranging a mountain photovoltaic power station. Background technique [0002] At present, the sites of large-scale ground power stations are generally selected in flat areas or mountainous areas with high north and low south. In anticipation planning, it is necessary to repeatedly conduct on-site surveys of the terrain, which consumes a lot of manpower and financial resources. [0003] To build a photovoltaic power station in a plain with gentle terrain, local field leveling can be carried out, and the array in the east-west direction will not produce shadows. When the row spacing is used, it should be avoided that the front row of square arrays blocks the back row of square arrays. Otherwise, not only will there be no power output in the shaded part, but also power consumption will form local heating and produce "hot spot effect". According to the geographi...

Problems solved by technology

[0013] Due to the limited state-owned unused land, most of the state-owned unused land is mountainous, the terrain is complex, and the slope of the site is steep. The mountain itself will produce a "yin and yang side". Not all areas can guarantee 6 hours of sunshine every day (9:00~15:00 00), it is difficult to analyze the sunshine situation of each area based on the topographic map alone, and it is impossible to accurately determine the layout area of ​​the photovoltaic array, and the cost of large-scale field leveling is very high, which is unrealistic. The calculation of the formula has brought great difficulties to the layout of the photovoltaic array
