Embodiment Construction

[0042] The mountainous photovoltaic power station site selection method based on DEM data implemented by the present invention ( figure 1 ) steps are the same as those described in the Summary of the Invention section. The input DEM data is 25 °~30 ° of north latitude, 100 °~105 ° of east longitude SRTM 90 meters of resolution original elevation data of Southwest China, according to the method of the present invention, automatically find out the area that satisfies the given site selection condition by computer. 17633 blocks, the largest area is 818098m 2 (The center point is at 102.037° east longitude, 29.608° north latitude), and the minimum area is 8099m 2 (The center point is at 102.328° east longitude and 27.219° north latitude). If the size is 1.638×0.982m 2 Take the 240W photovoltaic module as an example, the minimum required land area for a 1MW photovoltaic power station is 6709m 2 , then the installed capacity of photovoltaic power plants that can be built ...

Abstract

The invention relates to a mountainous region photovoltaic power station addressing method based on DEM data, and belongs to the technical fields of geographic information system and photovoltaic engineering. The steps of the method are listed as follows: an addressing region slope degree and slope direction digital landform model is established based on the DEM; if the slope degree of a certain point lies in the latitude range of +/-5 degrees of the location, and the slope direction lies in the range of +/-2 degrees of the right south direction, the photovoltaic power station is suitable to establish, and thus the certain point is marked; adjacent marked points are communicated, and addressing classification is performed and installation capacity of the photovoltaic power station in a certain mountainous region is calculated according to the size of area; and a KML script file is outputted, and Google Earth is applied to browse addressing results. According to the method, preliminary addressing of the photovoltaic power station can be rapidly completed and a basis for photovoltaic power station engineering design and labor field investigation is provided so that cost of photovoltaic power station is lowered and establishing speed is enhanced. Besides, analysis and evaluation can be performed on establishing potential of the photovoltaic power station on global geographic positions, and thus more detailed assessment can be performed on solar energy resources.

Description

Technical field: [0001] The invention relates to a site selection method for mountain photovoltaic power stations based on DEM data, belonging to the technical fields of geographic information systems and photovoltaic engineering. Background technique: [0002] Before the construction and planning of photovoltaic power plants, site selection must be carried out first. Reasonable location selection is very important to the output of light energy [1] , Unreasonable site selection will directly result in the loss of power generation and maintenance costs of the power station, the overall benefit and operating life will be reduced, and it will also cause adverse effects on the surrounding environment. The western region of China is rich in sunlight resources, but it does not have the vast and flat land suitable for the construction of large-scale photovoltaic projects like the northwest region. There are mostly mountains with complex terrains, and the conditions of the underlyi...
