Problems solved by technology

[0003] In the prior art, the method of grouping the module strings connected to the same combiner box in the photovoltaic field is mainly grouping by manual trial and error on drawings or drawing software. However, due to the huge number of module strings in the photovoltaic field, and if the design process In the case of site boundary changes or changes in site installation conditions that lead to changes in the arrangement of component strings, regrouping is required, resulting in a huge workload for manual grouping

Embodiment Construction

[0039] In order to make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0040] The first embodiment of the application provides a method for arranging a photovoltaic field combiner box, such as figure 1 As shown, the method includes the following steps:

[0041] Step S11, acquiring position information of each component string in the photovoltaic electric field;

[0042] Step S12, take the position of the southernmost module string in the photovoltaic field that has not yet been assigned to any module string sub-set as the southernmost end of the current group, and extend the preset north-south span from the southernmost end of the current group to the north as the northernmost end of the current group , Determine all component strings between the southernmost end of the current group and the northernmost end o...

Abstract

The invention belongs to the technical field of photovoltaic power generation and particularly relates to a method and device for arranging a photovoltaic electric field combiner box. According to themethod, component strings in a photovoltaic electric field are divided into a component string sub set, then the component strings in the component string sub set are orderly grouped to obtain multiple component string same-box groups, the sum of the distance of each component string in each component string same-box groups to a possible installation point of the combiner box is calculated, a possible installation point when a distance sum is smallest is taken as a cominber box arrangement position corresponding to the component string same-box group, and at that time, the length of a used cable is smallest according to a combiner box installation method. According to the method of the invention, the problems of time and manpower waste in the manual trial grouping of component strings ina photovoltaic electric field in the prior art can be solved, and engineering changes can be quickly responded by changing preset parameters to prevent an engineering delay.

Description

Technical field [0001] This application belongs to the technical field of photovoltaic power generation, and specifically relates to a method and device for arranging a photovoltaic field combiner box. Background technique [0002] There are often thousands of photovoltaic module strings in a photovoltaic electric field, which are distributed in photovoltaic fields with irregular boundaries. To convert the direct current generated by these component strings into alternating current, it is necessary to group the component strings in the photovoltaic field and connect them to the combiner box, and then connect the combiner box to the inverter and the inverter converts the direct current into alternating current. [0003] In the prior art, the method for grouping the component strings connected to the same combiner box in the photovoltaic electric field is mainly to group them manually on the drawing or drawing software. However, due to the huge number of component strings in the phot...
