Problems solved by technology

[0002] The photovoltaic area of ​​a photovoltaic power generation project covers a very large area. Taking a 100MW photovoltaic project as an example, the photovoltaic area covers an area of ​​about 1.8km 2 , which creates difficulties in the organization of PV cable laying work
[0003] The traditional way of laying photovoltaic PV cables is manual laying one by one. According to the drawing design, the PV cables are laid one by one from the terminal crimping joint of the photovoltaic panel along the groove of the photovoltaic bracket to the combiner box. According to statistics, the photovoltaic module with a power generation capacity of 1MW is about It is necessary to lay 21 kilometers of PV cables, and more than 140 round trips between the photovoltaic modules and the combiner box. It is time-consuming and labor-intensive to lay the cables, and the length of each cable cannot be accurately grasped, resulting in waste of PV cables and the need for secondary installation at the combiner box. tidy

Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific examples and accompanying drawings.

[0020] The invention provides a PV cable laying method for a large-scale photovoltaic power generation project, which includes the following steps:

[0021] S1. Obtain the PV cable parameters of each area according to the design partition of large-scale photovoltaic areas; figure 1 As shown, the design partition of S1 large-scale photovoltaic area includes standard area 1 and special-shaped area 2, and standard area 1 is designed according to 1MW.

[0022] S2. Export the PV cable parameters and process them. According to the distribution of the combiner boxes in different areas, compile the PV cable cutting table; the 1# and 2# combiner boxes in the standard area 1 are grouped according to the front row and the rear row, and the red and black lines are arranged. , 3#-12# combiner boxes are grouped according to the left side and right side, and the re...

Abstract

The invention provides a PV cable laying method for a large-scale photovoltaic generating project. The method includes the steps of obtaining PV cable parameters of each region according to design sub-region of a large-scale photovoltaic area, exporting and processing PV cable parameters, compiling a PV cable cutting table for distribution of combiner boxes in different regions, opening a plurality coils of PV cables according to the PV cable cutting table, fixing the head ends of the PV cables, cutting corresponding PV cables with automatic clippers, forming a set of PV branch cables through cutting for many times, marking according to the PV cable cutting table, placing the manufactured PV branch cables to corresponding combiner boxes in each region according to the marking contents, laying branch cables from the combiner boxes to the direction of a photovoltaic assembly, completing laying in one time, fixing one end of each PV cable at the corresponding combiner box with a cable radian controller during wire distribution, and reserving combiner box wiring radian. Parameters of all PV cables are obtained in advance, and PV cables are cut uniformly and grouped. Wire laying efficiency is thus improved.
