Abstract

The invention discloses a field orientation-combined tracking photovoltaic array arrangement method which comprises the steps of (1) calculating photovoltaic array arrangement spacing dNS' and dWE' in a north-south direction and an east-west direction after orientation angles gamma of photovoltaic device arrays change; (2) selecting the orientation angles gammai of m photovoltaic arrays, calculating the number Qi of photovoltaic devices which can be correspondingly arranged when the orientation angles of the m photovoltaic arrays are gammai separately and building a relationship model between the orientation angles gammai of the photovoltaic arrays and the arrangement number Qi of the photovoltaic devices; (3) calculating the relationship model between the orientation angles gammai of the photovoltaic arrays and solar radiation Hsingle (gammai) received by a single photovoltaic device all the year round and obtaining a relationship model between the solar radiation Htotal(gammai) received by a photovoltaic power station all the year round and gammai; (4) when the solar radiation Htotal(gammai) received by the photovoltaic power station all the year round is the maximum, taking the orientation angle gammai of the corresponding array as the optimum orientation angle gammaopt of the photovoltaic arrays; and (5) forming an array arrangement scheme of the photovoltaic devices in a photovoltaic field. By the method, array-type optimum arrangement of the photovoltaic devices can be achieved by combining the orientation of the photovoltaic field.

Description

technical field

[0001] The invention belongs to the technical field of photovoltaic power station construction, and relates to a tracking photovoltaic array arrangement method combined with site orientation. Background technique

[0002] When selecting the site of the power station, there will be a certain deflection angle between some construction sites and the due south direction. In such sites, the orientation of the traditional photovoltaic array arrangement is mostly consistent with the orientation of the site. Such an arrangement scheme will reduce the solar radiation received by the photovoltaic equipment. reduce the power generation of photovoltaic power plants. Therefore, considering the orientation characteristics of the site, designing an optimal arrangement method for tracking photovoltaic arrays with the goal of maximizing the solar radiation received by the power station throughout the year has important guiding significance for the construction of photovoltaic...
