Technical Field

[0001] The present invention belongs to the field of photovoltaic systems, and particularly relates to a method for arranging fixed supports for mountain photovoltaic power stations. Background Art

[0002] Regarding the utilization of renewable energy, photovoltaic and wind power are the most mature technologies and are also regarded as the most promising renewable energy utilization technologies in the future. The "Three-North Regions" of China are not only rich in wind energy resources but also rich in solar energy resources, suitable for the construction of large-scale wind farms and photovoltaic power stations. However, with the increasing number of photovoltaic power stations year by year, the land resources with good sunshine, flat terrain, and good construction conditions are decreasing day by day. Lands with secondary construction conditions such as agriculture, lakes, and mountains are gradually becoming the land construction resources for photovoltaic power stations. In particular, the construction of mountain photovoltaic power stations has gradually increased in recent years.

[0003] The construction of mountain photovoltaic power stations can make full use of land resources. Multiple small-capacity photovoltaic power generation systems are built on a small scale of land. It can flexibly select the construction environment, achieve decentralized investment and reduced risks, and can also meet small-scale electricity demand. A centralized mountain photovoltaic system is to centrally build multiple large-capacity photovoltaic power generation systems on a small amount of land. It can meet large-scale electricity demand, save construction costs, and while the overall power output area of the power station is stable, it can also reduce investment and improve efficiency.

[0004] However, when building a photovoltaic power station on a mountain, due to the undulating terrain of the mountain, if the fixed supports are arranged in the same way as on flat land, there will be a problem of waste of photovoltaic supports.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

[0006] In order to solve the technical problems existing in the prior art, the present invention provides a method for arranging fixed supports for mountain photovoltaic power stations. The photovoltaic fixed supports arranged by the method of the present invention can avoid waste of photovoltaic fixed supports and have higher utilization rates.

[0034] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0035] Figure 1 It is a flowchart of a method for arranging a mountain photovoltaic fixed support in an embodiment of the present invention. Detailed Embodiments

[0036] The following description provides many different embodiments or examples for implementing different features of the present invention. The elements and arrangements described in the following specific examples are only used to concisely express the present invention, and they are only examples and not intended to limit the present invention.

[0037] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features.

[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0039] This embodiment provides a method for arranging fixed photovoltaic brackets in mountainous areas, as Figure 1 shown, including the following steps:

[0040] Obtain the construction area of the mountainous area to be constructed;

[0041] Arrange the first fixed photovoltaic brackets at the edge of the construction area, and then, according to sunlight analysis, sequentially arrange the second fixed photovoltaic brackets from the edge of the construction area inward until the arrangement of the fixed photovoltaic brackets in the construction area is completed;

[0042] Among them, the fixed photovoltaic brackets include the first fixed photovoltaic brackets and the second fixed photovoltaic brackets. In the present invention, the first fixed photovoltaic brackets and the second fixed photovoltaic brackets are used to distinguish different positions where the photovoltaic brackets are set, that is, the fixed photovoltaic brackets set at the edge of the construction area are all the first fixed photovoltaic brackets, and the fixed photovoltaic brackets set within the first fixed photovoltaic brackets are all the second fixed photovoltaic brackets.

[0043] It should be noted that since the construction area may be a regular figure or an irregular figure; therefore, the shape enclosed by the first fixed photovoltaic brackets and the second fixed photovoltaic brackets arranged at its edge may also be a regular figure or an irregular figure.

[0044] Furthermore, the obtaining of the construction area includes the following steps:

[0045] Perform three-dimensional modeling on the terrain of the mountain to obtain a model;

[0046] Combine the movement of the sun to obtain the constantly shaded areas within the mountain;

[0047] Remove the constantly shaded areas from the model to obtain the construction area;

[0048] Among them: The constantly shaded area is the area that has no sunlight for 24 hours.

[0049] Based on this, excluding the areas that cannot be directly irradiated by sunlight from the construction area has the advantages of improving the utilization efficiency of the fixed photovoltaic brackets and reducing costs at the same time.

[0050] Furthermore, use Civil 3D for three-dimensional modeling.

[0051] China is located in the mid-high latitudes of the Northern Hemisphere, which means that the sun always appears to be a bit more southerly in China. Whether it is the summer solstice or other seasons, the rising and setting positions of the sun in China are relatively southerly. Therefore, in order to increase the sunlight exposure time and the utilization efficiency of the fixed photovoltaic brackets, furthermore, the arrangement of the fixed photovoltaic brackets in the construction area is:

[0052] From north to south, the altitude of the photovoltaic fixed brackets decreases in sequence;

[0053] From west to east, the altitude of the photovoltaic fixed brackets increases first and then decreases in sequence.

[0054] This can ensure that there is no shaded area in the north-south photovoltaic fixed brackets, improving the utilization efficiency of the north-south photovoltaic fixed brackets.

[0055] Furthermore, arranging the first photovoltaic fixed brackets at the edge of the construction area includes the following steps:

[0056] Arrange the first photovoltaic fixed brackets in the east of the construction area;

[0057] Combine the movement trajectory of the sun and the shadow of the first photovoltaic fixed brackets to arrange the first photovoltaic fixed brackets in the south and north of the construction area;

[0058] Arrange the first photovoltaic fixed brackets in the west of the construction area.

[0059] Furthermore, obtain the first interval distance between adjacent first photovoltaic fixed brackets through the movement trajectory of the sun and the shadow of the first photovoltaic fixed brackets; arrange the first photovoltaic fixed brackets in the south and north of the construction area according to the first interval distance.

[0060] Furthermore, the second photovoltaic brackets are arranged gradually from the position close to the first photovoltaic brackets towards the center of the construction area; specifically, the second photovoltaic brackets are arranged inwards in circles when being arranged; because the sun has a certain movement trajectory, if only considering the shadow from one direction when arranging the photovoltaic fixed brackets, the utilization rate of the light in other directions will not be high enough; and arranging the second photovoltaic fixed brackets in this way fully considers the shadow effects in all directions, thereby improving the utilization rate of light and photovoltaic fixed brackets.

[0061] Furthermore, arranging the second photovoltaic fixed brackets at the edge of the construction area includes the following steps:

[0062] Arrange the second photovoltaic fixed brackets in the east of the construction area;

[0063] Combine the movement trajectory of the sun and the shadow of the second photovoltaic fixed brackets to arrange the second photovoltaic fixed brackets in the south and north of the construction area;

[0064] Arrange the second photovoltaic fixed brackets in the west of the construction area.

[0065] Furthermore, obtain the second interval distance between adjacent second photovoltaic fixed brackets through the movement trajectory of the sun, the shadow of the first photovoltaic fixed brackets and the shadow of the second photovoltaic fixed brackets; arrange the second photovoltaic fixed brackets in the south and north of the construction area according to the second interval distance.

[0066] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
