Abstract

The invention discloses a grid fault-tolerant correction method for a photovoltaic support. The method comprises the following steps: configuring support scene attributes and performing numerical expression on the support scene attributes; acquiring and forming a grid sample set according to the numerical expression of the support scene attributes, and simultaneously acquiring an expert sample set and a to-be-detected sample set; performing zero-sum game network training solidification on the grid sample set by using the expert sample set to obtain an expert sample extension set; training a self-organizing competition network model by using the to-be-detected sample set, the grid sample set and the expert sample extension set; and inputting the support scene attribute of the target photovoltaic support into the self-organizing competitive network model to obtain a gridding fault-tolerant parameter vector for matching correction. Through configuration of support positioning scene attributes and grid management of a narrow-domain interval judgment matrix, light resource scene generation in a maximum fault-tolerant range is realized. And power generation loss caused by shadow shielding is avoided, and operation and maintenance management in a construction stage is realized.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to a gridded error-tolerant deviation correction method for photovoltaic supports. Background technique [0002] During the design process of the photovoltaic power station, the designers arrange the photovoltaic modules and support arrays according to the extreme design plan from 9:00 a.m. to 15:00 p.m. on the winter solstice, which fully meets the design needs without considering the microscopic site selection. However, in the actual construction process, due to the unevenness of the site, the influence of buildings or bushes, the shadow blocking will inevitably lead to the reduction of power generation. Especially for the installation of photovoltaic brackets on mountainous or hilly landforms, the loss of power generation caused by shading may not meet the terms of the contract. Contents of the invention [0003] In view of the above-mentioned deficiencies currently existing, the ...
