Description

Technical Field

[0001] The present invention relates to the technical field of the overall layout of solar thermal power plants, and specifically, to a vertical layout method, device, and storage medium suitable for a hybrid stepped and gentle slope in a solar thermal power plant. Background Art

[0002] When building a solar thermal power generation station in a complex terrain area, the terrain has large undulations, which brings many challenges to the layout and design of the energy system. Especially in the solar thermal mirror field area, the natural height difference may reach dozens of meters. Directly arranging the energy system will cause the height difference between the heat transfer oil system and key areas such as the main plant building to exceed the design requirements, thus affecting the stable flow of the heat transfer oil, increasing energy loss, and raising the construction cost. In addition, the construction difficulty and climatic conditions under complex terrain further increase the complexity of the project. Therefore, how to reasonably control the height difference and optimize the energy system layout under complex terrain conditions with significant height differences has become an urgent technical problem in solar thermal power generation projects.

[0026] Embodiment 1

[0027] This embodiment provides a vertical layout method suitable for a hybrid stepped and gentle slope in a solar thermal power station. The specific steps are as follows:

[0028] 1. Variable definition: including the total height difference ΔH, the maximum height difference limit Δh max , the number of steps n, the height h of each step i , the gentle slope gradient limit S max , the gentle slope gradient S, the gentle slope length L i , the earthwork balance coefficient k, the earthwork volume Q of each step i , the length L of the heat transfer oil pipeline p , etc.

[0029] 2. Height difference segmentation: Confirm the maximum height difference limit Δh allowed for the heat transfer oil system and other key areas max , and decompose the total height difference ΔH into multiple smaller height differences h i , ensuring that the height difference h of each step i ≤Δh max .

[0030] 3. Optimization according to the mathematical model:

[0031] (1) Objective function: Construct a hierarchical optimization objective in the order of priority.

[0032] (a) Minimize the number of steps n.

[0033] (b) Optimize the gentle slope length L i and position to promote earthwork balance and reuse.

[0034] (c) Minimize the total construction work volume and construction cost C.

[0035] (2) Constraints:

[0036] (a) Total height difference constraint:

[0037] (b) The height difference of each step does not exceed the maximum limit: h i ≤Δh max (i = 1, 2, …, n)

[0038] (c) Relationship between gentle slope length and step height difference:

[0039] (d) Earthwork balance and reuse: Q i =A×h i ×k (i = 1, 2, …, n), where A is the area of the step (square meters) and k is the earthwork balance coefficient.

[0040] (e) Non-negativity constraint: h i ≥0 (i = 1, 2, …, n), L i ≥0 (i = 1, 2, …, n−1), Q i ≥0

[0041] (i = 1, 2, …, n)

[0042] (f) Integer constraint:

[0043] Specific implementation steps:

[0044] (1) Terrain analysis and sectional design:

[0045] (a) Determine the total height difference ΔH (e.g., 100 meters) through topographic survey data.

[0046] (b) Calculate the minimum number of steps n according to the maximum height difference limit Δh max (e.g., 27 meters): (e.g., 4)

[0047] (2) Step height allocation:

[0048] Design n steps and allocate the height h of each step i (For example, 27 meters, 25 meters, 25 meters, 23 meters).

[0049] (3) Calculation of gentle slope length

[0050] (a) Calculate the gentle slope length L according to the gentle slope gradient limit S max (For example, 5%), i (For example, 540 meters, 500 meters, 500 meters, 460 meters)

[0051] (b) The lengths of each gentle slope may not immediately match the terrain conditions. Therefore, it is necessary to adjust the gradient, reallocate the step height, and increase the number of steps according to the actual situation to optimize the gentle slope length and position.

[0052] (4) Earthwork balance and reuse:

[0053] (a) Design the earthwork volume to ensure that the excavation and filling are basically balanced, and use the excavated earthwork of each section of the steps for the filling of the next section of the steps.

[0054] (b) Reserve part of the earthwork for future system expansion or maintenance.

[0055] (5) Optimization of the layout of heat transfer oil pipelines:

[0056] (a) Mainly arrange the heat transfer oil pipelines in the gentle slope transition area to reduce the path length and energy loss.

[0057] (b) Reserve standardized oil supply and return oil interfaces in the gentle slope transition area to facilitate future system expansion and maintenance.

[0058] (6) Optimization of construction workload and construction cost

[0059] After considering factors such as the number of steps, gentle slope length, earthwork volume, and civil engineering workload other than the earthwork volume, calculate the total cost, and further optimize the layout plan of the steps and gentle slopes with the goal of optimizing the cost.

[0060] (Optional) Set weight coefficients for each factor to make it easier to optimize the total cost. Its mathematical model is:

[0061]

[0062] Among them, α 1 , α 2 , α 3 ,... are weight coefficients, reflecting the influence of each factor such as the number of steps, gentle slope length, earthwork volume, etc. on the total cost. This formula is an expandable form, allowing more influencing factors to be added according to actual needs.
