Problems solved by technology

[0003] Using the general manual method to arrange photovoltaic square arrays requires a lot of complex calculations, which is time-consuming and inefficient. Repeated iterations are required to adjust some parameters, which requires substantial adjustments, and even requires repeated layouts from scratch, and the adjustment direction is not clear. , can't see results quickly
Especially for complex terrain, the general manual method of layout will greatly increase the workload, and the optimality of the layout results cannot be guaranteed

Abstract

The invention relates to a method for automatically arranging a photovoltaic array in a complex terrain. The method comprises the steps of (1) calculating amount of solar radiation according to the current latitude so as to calculate an optimum tilt angle; (2) carrying out preliminary division on a given region; (3) carrying out occlusion calculation so as to calculate a shadow area, marking the calculated shadow area, and adjusting areas obtained in the step (2); (4) performing photovoltaic array grid division on the area to be arranged, and carrying out initial arrangement; (5) performing inverter grid division on the area to be arranged; (6) determining the arrangement positions of an inverter and a combiner box. In the steps (1), (2) and (3), the tilt angle and initial area to be arranged of the photovoltaic array are determined, and the arrangement of the photovoltaic array is well prepared; on this basis, the comprehensive optimal arrangement of the photovoltaic array is realized by means of the steps (4), (5) and (6).

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a method for automatically arranging a photovoltaic array, in particular to a method for automatically arranging a photovoltaic array on the premise of complex terrain. Background technique [0002] The layout of the photovoltaic array needs to comprehensively consider the amount of light and output power, that is, the influence of the inclination and orientation of the photovoltaic array on the amount of light, and the mutual shading of the photovoltaic arrays. [0003] Using the general manual method to arrange photovoltaic square arrays requires a lot of complex calculations, which is time-consuming and inefficient. Repeated iterations are required to adjust some parameters, which requires substantial adjustments, and even requires repeated layouts from scratch, and the adjustment direction is not clear. , can not see the results soon. Especi...
