Abstract

The invention discloses a method for calculating the radiation quantity of a mountain photovoltaic array. The method comprises the following steps: establishing a triangulation network terrain elevation model according to actual terrain data of a mountain; arranging a photovoltaic array plane layout diagram at a proper position in the triangulation network terrain elevation model; and performing rotation adjustment on the position of each photovoltaic array according to the triangulation network terrain elevation model to generate a photovoltaic array three-dimensional arrangement model, extracting actual inclination angle and azimuth angle values of all the photovoltaic arrays from the photovoltaic array three-dimensional model, and calculating the total radiation quantity of all the photovoltaic arrays according to the extracted actual inclination angle and azimuth angle values. According to the method, the total radiation quantity of the photovoltaic arrays with different inclined planes and different azimuth angles can be accurately calculated in batches, the method is simple, the calculation result accuracy is high, and effective parameters are provided for accurately calculating the generating capacity of the mountain photovoltaic engineering.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power stations, and in particular relates to a method for calculating the radiation amount of a mountain photovoltaic array. Background technique [0002] In recent years, as the terrain is flat and the land resources with good construction conditions are decreasing, it cannot meet the needs of photovoltaic power station construction in the process of vigorous development. The number of photovoltaic power stations built gradually using complex terrain such as hills and mountains is increasing. [0003] In conventional engineering, it is often assumed that the inclination and azimuth angles of all photovoltaic arrays are the same value to calculate the radiation on the photovoltaic array surface. However, the actual inclination and azimuth angle values ​​of photovoltaic arrays in mountainous photovoltaic projects are different, and conventional methods cannot calculate the radiation of a larg...
