Description

Technical Field

[0001] The present invention relates to the technical field of steam transportation in an isolated power generation system, and in particular to a method, device, equipment and medium for arranging a steam main frame of an isolated power generation system in a plateau. Background Art

[0002] The isolated grid power generation system is a power generation mode that operates independently of the large power grid and is widely used in energy supply scenarios in remote areas. The Zabuye Salt Lake area is famous for its rich solar energy and geothermal resources. Its energy development direction often adopts centralized power generation technologies such as solar thermal power generation and geothermal power generation. The efficient utilization of these energy forms requires a complete energy transmission path, among which the steam main frame is the key path for energy transmission in the isolated grid power generation system. The steam main is responsible for transporting high-temperature and high-pressure steam from the solar thermal oil heat exchanger or geothermal equipment, and distributing it to power generation equipment (such as steam turbines), heat storage systems, and recovery systems, thereby realizing efficient conversion and utilization of energy.

[0003] However, the existing steam main frame layout is mainly based on traditional artificial design schemes, which highlights the following problems in complex terrain environments such as the Zabuye Salt Lake:

[0004] 1. The pipeline path is circuitous, increasing operating costs and energy loss

[0005] In traditional designs, the route of the steam main frame is mostly based on manual line selection, without fully considering the regional terrain, relative layout between equipment and the characteristics of the conveying medium for optimization design. The main problems include:

[0006] (1) The length of the pipe rack is too long: In order to avoid infrastructure or adapt to complex terrain (such as the Zabuye Salt Lake, which has a large terrain undulation and many salt crusts and muddy sediments on the surface), the route design needs to be detoured, resulting in a significant increase in the length of the pipeline.

[0007] (2) High material and construction costs: Long-distance pipeline layout requires more materials and supporting structures, which increases the initial investment and increases the cost of pipeline protection (such as insulation and anti-corrosion).

[0008] (3) Increased heat loss: When steam is transported through a long pipeline, due to heat dissipation from the pipe wall and fluid friction, significant energy loss will occur, which is not conducive to long-term stable energy supply under sinusoidal load changes of the isolated grid.

[0009] In high-altitude cold areas such as Zabuye Salt Lake, the ambient temperature is low most of the time, and the heat loss when high-temperature steam passes through the pipeline is particularly obvious. Therefore, while ensuring the transportation effect, the pipeline length should be shortened as much as possible to reduce heat loss.

[0010] 2. Equipment partition design lacks consideration of overall process fluidity, affecting energy efficiency

[0011] Steam transmission in an isolated power generation system needs to pass through multiple key equipment, including the thermal oil heat exchange area (or geothermal facilities), steam generation system, heat storage device and steam turbine. In traditional practices, each zone equipment is often located relatively independently, without fully considering the overall process fluidity:

[0012] (1) Fragmented regional layout: The location selection of each equipment partition is centered on the needs of the individual equipment, and the location is not determined from the perspective of overall process performance optimization, which requires the steam path between adjacent equipment to detour or even turn back multiple times.

[0013] (2) Uneven steam flow: Improper pipeline design may lead to uneven pressure distribution, resulting in problems such as decreased flow rate in some process sections and accumulation of condensate, thus affecting the power generation or energy storage performance of the entire system.

[0014] (3) Increased difficulty in construction and maintenance: The connections between the pipeline partitions are complicated and the spaces are staggered, which will cause inconvenience and even potential accidents during the subsequent operation and maintenance.

[0015] In an environment like Zabuye Salt Lake with significant terrain changes and limited infrastructure, the above problems will be further amplified, so there is an urgent need for a new method to optimize equipment zoning and pipeline path design from a global perspective.

[0016] 3. Lack of dynamic adjustment capability limits the adaptability of the isolated grid system to complex working conditions

[0017] The isolated power generation system is affected by many external and internal factors during operation, such as fluctuations in solar radiation intensity, seasonal climate changes, uncertainty in power load, etc. These factors require the steam main frame to have a certain dynamic adjustment capability to adapt to fluctuations in energy demand. However, the current design has the following shortcomings:

[0018] (1) Lack of dynamic adjustment design, unable to flexibly adjust the layout plan according to the actual usage scenario.

[0019] (2) Complex maintenance and delayed response: Due to the complex pipeline layout, it is difficult to dynamically adjust the line when a fault occurs, and the maintenance cycle is long, which affects the system's ability to continuously supply energy. In addition, in remote areas such as the Zabuye Salt Lake, maintenance personnel and resources are limited, making flexible and reliable dynamic adjustment particularly important.

[0020] 4. The adverse impact of geographical environment on traditional layout

[0021] As one of the highest salt lakes in the world, the geographical environment of Zabuye Salt Lake brings many challenges:

[0022] (1) Harsh natural conditions: Zabuye is in a typical alpine region with extremely low winter temperatures, while in summer, there may be intense sunlight and strong ultraviolet radiation, which requires higher requirements for pipeline insulation and durability.

[0023] (2) Topographical complexity: The surface of the salt crust layer in the region is fragile and the humidity of the underground muddy sediment is high, which restricts the building load and pipeline support design.

[0024] (3) Logistics and construction limitations: The transportation conditions are relatively poor, and the transportation cycle of large equipment and materials is long and the cost is high, especially for the components required for longer pipelines.

[0025] Therefore, in the construction of an isolated power grid project in the Zabuye Salt Lake area, there is an urgent need for a method that can adapt to complex natural environments, reduce energy loss and simplify construction at the same time, while the traditional solutions have shown obvious deficiencies in practice.

[0075] Please refer to Figure 1 , which shows a flowchart of a steam main pipe rack layout method for a plateau isolated power grid provided by an embodiment of the present invention. The steam main pipe rack layout method for a plateau isolated power grid includes the following steps:

[0076] Step S1: Based on the database, obtain the layout plans and plan features of the main plant building, heat transfer oil system, and SGS area;

[0077] Step S2: Based on the environmental characteristics and the principle of the shortest path, determine the I-shaped layout plan and path constraint rules for the main plant building, heat transfer oil system, and SGS area;

[0078] Step S3: Obtain the regional coordinates, boundary data, and environmental constraints;

[0079] Step S4: Based on the regional coordinates, boundary data, environmental constraints, Type-I layout plan, and path constraint rules, obtain multiple candidate paths;

[0080] Step S5: Use an intelligent algorithm to optimize the multiple candidate paths and output the optimal layout diagram.

[0081] In an alternative embodiment, the main plant building, heat transfer oil system, and SGS area layout plans and their characteristics in the above Step S1 are shown in the following table:

[0082]

[0083] In an alternative embodiment, the path constraint principles in the above Step S2 include straight-line priority, separation of the main trunk and branches, and elevation difference matching.

[0084] Specifically, straight-line priority: The pipeline layout follows the rule of giving priority to the shortest direct connection path among three points. If the direct connection path is blocked, the path optimization algorithm needs to consider the second-shortest path;

[0085] Separation of the main trunk and branches: The main steam pipe rack is arranged as the main trunk on the central channel, and its key branch roads are connected to the heat storage area and the heat transfer oil area without overlapping arrangements; ensure that the main trunk path is fixed while the branch paths are flexible and adjustable;

[0086] Elevation difference matching: There may be height differences in the facilities where the heat storage equipment and the heat transfer oil pump station are located. By establishing a gentle slope section (meeting the standard bending radius) to reduce the pipeline stress and avoid excessive pressure drop caused by sharp turns at the same time.

[0087] In an alternative embodiment, the above Step S3 may include:

[0088] Obtain the coordinate positions, boundary data, and environmental constraints of the main plant building, heat transfer oil area, and SGS area;

[0089] Among them, the coordinate positions include plane coordinates and height coordinates; the boundary data indicates the spatial data that needs to be avoided between regions; the environmental constraints include terrain data, elevation difference change data, and climate conditions.

[0090] In an alternative embodiment, the above Step S4 may include:

[0091] Based on the regional coordinates, determine the starting point and ending point of the path;

[0092] Based on the path constraint rules, use the initial search algorithm to calculate the shortest straight-line connection paths between the main plant building, heat transfer oil area, and SGS area, and obtain multiple shortest paths;

[0093] Adjust multiple shortest paths based on boundary data, environmental constraints, and preset rules to obtain multiple candidate paths; the preset rules include obstacle avoidance, climb angle limitation, and structural strength requirements.

[0094] Discretize the candidate paths to obtain discretized paths.

[0095] In an alternative embodiment, in step S5 above, genetic algorithms, ant colony algorithms, particle swarm algorithms, multi-constraint optimization algorithms, or zebra algorithms can be used for optimization.

[0096] Specifically, in the case of using a genetic algorithm, it includes:

[0097] Initialize the population composed of discretized paths to obtain an initialized population.

[0098] Calculate the fitness function for the initialized population, and define the fitness value of each discretized path according to the objective function.

[0099] Select discretized paths that meet the preset conditions according to the fitness value.

[0100] Perform crossover operations on the discretized paths that meet the preset conditions to generate new candidate paths.

[0101] Randomly adjust the offset positions and height adjustment values of some connection points to expand the search range and jump out of the local optimal solution.

[0102] Continuously iterate to produce a new population until the fitness value no longer increases significantly or reaches the set number of iterations, and then output the optimal layout diagram.

[0103] In an alternative embodiment, between step S4 and step S5 above, there is also a step of evaluating the energy and cost of the discretized paths, specifically including:

[0104] Calculate the energy loss and cost value of each discretized path, and exclude or repair the discretized paths that do not meet the preset threshold.

[0105] Specifically, during energy evaluation, the steam fluid dynamic characteristics, such as pressure drop and heat loss, can be calculated for each section of the path.

[0106] Pressure drop calculation formula: ΔP = f·L / D·ρv 2 / 2;

[0107] Where: f: friction coefficient; L: pipe section length; D: pipe diameter; ρ: steam density; v: steam flow velocity.

[0108] Heat loss calculation formula: Q loss = U·A·(T steam -T env )

[0109] Wherein: U: heat transfer coefficient of the insulation layer; A: surface area of the pipe; T steam : steam temperature; T env : ambient temperature;

[0110] Sort the energy losses of all discretized paths according to the above formula, and eliminate the paths that do not meet the hydrodynamic performance requirements (such as excessive pressure drop).

[0111] During cost evaluation, the cost of each section of the pipeline can be calculated, including:

[0112] Material cost per unit length of the main steam pipe and supports;

[0113] Costs of auxiliary equipment such as thermal expansion compensators and valves;

[0114] Cost adjustment value for installation construction difficulty based on different height differences and climbing angles;

[0115] Environment-related costs (such as the cost of thickened insulation).

[0116] Finally, calculate the total cost value for each complete path to form an initial set of discretized paths.

[0117] By applying an intelligent algorithm to optimize the design of the main steam pipe rack, this method can efficiently generate a flexible and economically reasonable layout plan, improve the energy transmission efficiency, and reduce the construction and operation costs. At the same time, this method solves the problem of multi-constraint adaptation in the traditional design process and is particularly applicable to complex natural environment scenarios (such as Zabuye Salt Lake area).
