Description

Technical Field

[0001] The present invention relates to the technical field of compressed air energy storage engineering, and in particular to a layout structure of a 100-megawatt-class compressed air energy storage power station. Background Art

[0002] Currently, 100-megawatt compressed air power plants are large in scale, complex in equipment, require extensive gas storage space, and require complex pipeline layouts and well-defined zoning. These typically utilize large centrifugal or axial-flow compressors and large multi-stage turbines. These devices require extensive plant installation and large lifting equipment and other auxiliary facilities for easy inspection and maintenance. Furthermore, the heat exchangers in 100-megawatt compressed air energy storage plants must handle the increased heat exchange required, typically employing large centralized heat exchangers.

[0003] The existing 100-megawatt compressed air energy storage power stations have at least the following shortcomings:

[0004] (1) The compressor and turbine are installed in the same plant and arranged close to each other. Due to the large differences in the overall dimensions, weight, and maximum maintenance lifting weight of the compressor and turbine, the main plant design is not compact enough, the space utilization is low, and the plant height is relatively high;

[0005] (2) The compressor and turbine are arranged on the same side of the heat exchanger, while there are many air coolers and air heaters. The footprint of the heat exchanger area is significantly different from that of the compressor and turbine, resulting in a long compressed air pipeline and an unsmooth layout. At the same time, some existing compressed air energy storage power stations have dispersed radiators, which requires the compressor and turbine to be equipped with independent distributed heat exchangers. This undoubtedly increases the complexity of the equipment and the floor space of the main plant.

[0006] Based on this, it is necessary to design a 100-megawatt compressed air energy storage power station layout structure to solve the problems existing in the existing technology. Summary of the Invention

[0034] The technical solution provided by the present invention is described below with reference to the accompanying drawings and specific implementation methods.

[0035] Combine Figures 1 to 3 As shown, this embodiment provides a layout structure for a 100-megawatt compressed air energy storage power station (hereinafter referred to as the "layout structure"), which primarily includes a compressor room 1, a turbine room 2, a cooler area 3, a heater area 4, a cooling area compressed air corridor 5, a heating area compressed air corridor 6, and a thermal storage medium corridor. The thermal storage medium corridor is used to arrange hot and cold thermal storage circulating water pipelines 71. The thermal storage medium corridor is connected to the cooler area 3 and the heater area 4 on both sides. The side of the cooler area 3 away from the thermal storage medium corridor is connected to the cooling area compressed air corridor 5, and the side of the heater area 4 away from the thermal storage medium corridor is connected to the heater compressed air corridor. The compressor room 1 is arranged on the side close to the cooling area compressed air corridor 5, and the turbine room 2 is arranged on the side close to the heating area compressed air corridor 6.

[0036] In the layout structure provided in this embodiment, the area where the cooler area 3, the heater area 4, the cooling area compressed air pipeline corridor 5, the heating area compressed air pipeline corridor 6 and the heat storage medium pipeline corridor are located is defined as the heat exchange area. By arranging the compressor room 1 and the turbine room 2 on both sides of the heat exchange area, the room sizes of the compressor room 1 and the turbine room 2 can be reasonably planned according to the external dimensions of the compressor 111 and the turbine 211, respectively, reducing the floor space occupied by the blank area in the layout structure and ensuring the compactness of the design of the compressor room 1 and the turbine room 2; in addition, by comprehensively planning the cooler area 3, the heater area 4, the cooling area compressed air pipeline corridor 5, the heating area compressed air pipeline corridor 6 and the heat storage medium pipeline corridor according to the process, they are integrated into an integrated setting instead of being dispersed, which helps to improve the smoothness of the pipeline layout, reduce pipeline crossings and the length of the compressed air pipeline and the hot water exchange pipeline, reduce the difficulty of pipeline layout, and make the pipeline smooth and short. By independently arranging the compressor room 1 and the turbine room 2, and centrally arranging the cooler area 3, the heater area 4, the cooling area compressed air pipeline corridor 5, the heating area compressed air pipeline corridor 6 and the heat storage medium pipeline corridor, the structure is more compact than the existing compressed air plant layout, which can significantly improve the space utilization rate of the layout structure, thereby helping to reduce the floor space of the layout structure, reducing layout costs and space waste.

[0037] In this embodiment, the compressor room 1 includes a compressor unit module 11 and a first electronic control module 12. The compressor unit module 11 includes multiple compressors 111, which are arranged horizontally in order of operating pressure from low to high. The first electronic control module 12 is arranged on the side of the compressor unit module 11 away from the compressed air corridor 5 in the cooling area. The first electronic control module 12 includes equipment such as a high-voltage inverter room, an electronic equipment room, a low-voltage power distribution room, and a "DC + UPS" equipment room. In other words, this embodiment can centrally arrange the compressors 111 and the electrical equipment, power electronic equipment, and control equipment connected to the compressors 111 within the compressor room 1 and arrange them in a modular manner. This not only reduces the complexity of facilities such as cables, making the cables smooth and short, but also shortens the ineffective distance between the compressor unit module 11 and the first electronic control module 12, further optimizing the equipment layout and improving operational efficiency, overall energy efficiency, and ease of operation and maintenance.

[0038] Optionally, in this embodiment, the compressor module 11 further includes a lubricating oil station 112. Depending on the number of compressors 111, a shared lubricating oil station 112 is provided between every two adjacent compressors 111. For example, in this embodiment, there are four compressors 111 and two lubricating oil stations 112, with one compressor 111 positioned on either side of each lubricating oil station 112. In this embodiment, the lubricating oil station 112 specifically includes components such as a lubricating oil pump, an oil cooler, a filter, and an oil tank to effectively lubricate the compressors 111.

[0039] It should be noted that the height of the compressor room 1 is determined by the height of the maximum maintenance parts of the compressor 111, the installation height of the largest compressor 111, and the external height of the largest compressor 111. Therefore, the height of the compressor room 1 can be constructed according to actual conditions to ensure that the height of the compressor room 1 is controlled within an appropriate range, avoiding being too low to affect the assembly and maintenance of the compressor 111, or being too high to waste space and materials.

[0040] Optionally, the compressor unit module 11 also includes a public maintenance area 113, an maintenance door 114, and a maintenance and operation connection platform 115. The public maintenance area 113 facilitates the removal of large maintenance parts. In this embodiment, the public maintenance area 113 is arranged between the two compressors 111 in the middle, which helps to reduce the moving distance when reaching each compressor 111, and the operation and maintenance efficiency is faster; the maintenance door 114 is set on the wall of the compressor room 1 and is arranged corresponding to the public maintenance area 113, which facilitates the removal of large maintenance parts. The maintenance and operation connection platform 115 is arranged between each two adjacent compressors 111, which makes it convenient for maintenance personnel to walk between the compressors 111, thereby facilitating the inspection of each compressor 111.

[0041] Optionally, in this embodiment, the compressor room 1 further includes a first muffler module (not shown in the figure), the first muffler module including a compressor anti-surge vent pipe, a valve and a first vent muffler, wherein one end of the compressor anti-surge vent pipe is connected to the compressor unit module 11 through a valve, and the other end of the compressor anti-surge vent pipe is connected to the first vent muffler. In the above setting, the design of the first vent muffler can reduce the noise generated during gas discharge, thereby improving the comfort of the working environment and meeting the noise control standards. In addition, this configuration helps to reduce the vibration and impact of the compressor 111 equipment, thereby increasing the service life of the compressor 111 equipment.

[0042] refer to Figure 3 As shown, in this embodiment, the turbine room 2 includes a turbine unit module 21 and a second electric control module 22, wherein the turbine unit module 21 includes a turbine 211, an EH oil container 212, a lubricating oil container 213, a maintenance area 214, a generator output equipment room 215, and an excitation room 216. The high-pressure cylinder 2111 and the low-pressure cylinder 2112 of the turbine 211 are arranged in a direction parallel to the length direction of the turbine room 2 (refer to FIG. 2 ). Figure 1The high-pressure cylinder 2111 of the turbine 211 is provided with the above-mentioned EH oil container 212, lubricating oil container 213 and maintenance area 214 on one side, and the low-pressure cylinder 2112 of the turbine 211 is provided with the above-mentioned generator output equipment room 215 and excitation room 216 on one side; the second electronic control module 22 is arranged on the side of the turbine unit module 21 away from the compressed air pipeline gallery 6 in the heating area.

[0043] It should be noted that, in this embodiment, the components of the second electronic control module 22 are basically the same as those of the first electronic control module 12, that is, the second electronic control module 22 also includes equipment such as a high-voltage inverter room, an electronic equipment room, a low-voltage distribution room, and a "DC + UPS" equipment room. In other words, this embodiment can centrally arrange the turbine 211 and the electrical equipment, power electronic equipment, and control equipment connected to the turbine 211 in the turbine room 2, eliminating the measure of centrally arranging the first electronic control module 12 and the second electronic control module 22 in a centralized control building. This not only reduces the layout complexity of facilities such as cable wiring, making the cables smooth and short, but also effectively shortens the distance between the turbine unit module 21 and the second electronic control module 22, thereby further optimizing the layout between the various components in the turbine room 2, thereby improving the operating efficiency, overall energy efficiency, and operation and maintenance convenience of the turbine room 2.

[0044] Optionally, refer to Figure 1 As shown, the layout provided in this embodiment also includes a transformer area 8. Along the length of the turbine room 2, the transformer area 8 is located near the generator outgoing equipment room 215 and is electrically connected to the turbine 211. This shortens the distance between the busbars in the generator outgoing equipment room 215 and the 10 kV busbars in the transformer area 8, reducing cable costs and further enhancing the compactness of the layout. In this embodiment, the power transmission area C is located near the transformer area 8, facilitating power transmission and grid access, effectively reducing cable length.

[0045] Optionally, in this embodiment, the turbine room 2 further includes a second muffler module (not shown in the figure), which includes a low-pressure cylinder exhaust pipe and a second vent muffler. One end of the low-pressure cylinder exhaust pipe is connected to the turbine unit module 21, and the other end of the low-pressure cylinder exhaust pipe is connected to the second vent muffler. Through the above configuration, the second vent muffler can suppress the noise generated during the gas discharge process, preventing it from propagating to the surrounding environment, thereby improving the working environment quality of the turbine room 2. In addition, this design helps to reduce vibration and pressure fluctuations during the exhaust process, further improving the stability and efficiency of the turbine room 2 during application.

[0046] In this embodiment, the cold and hot heat storage circulating water pipes include a heat storage circulating cooling water supply and return pipe 711 and a heat storage circulating heating water supply and return pipe 712, wherein the heat storage circulating cooling water supply and return pipe 711 is arranged on the side close to the cooler area 3, and the heat storage circulating heating water supply and return pipe 712 is arranged on the side close to the heater area 4, so that the heat storage circulating cooling water supply and return pipe 711 and the heat storage circulating heating water supply and return pipe 712 can be arranged side by side, making the pipeline layout of the cold and hot heat storage circulating water pipes more reasonable, and achieving the design purpose of reducing the length of the cold and hot heat storage circulating water pipes and reducing the crossing of the pipes.

[0047] Furthermore, the heat storage cycle cooling water supply and return pipes 711 and the heat storage cycle heating water supply and return pipes 712 are both arranged in an overhead manner, which helps to reduce land occupation, facilitates the movement of operation and maintenance personnel, and ensures the safety of operation and maintenance personnel during the operation and maintenance process.

[0048] Optionally, the compressed air pipes arranged in the cooling zone compressed air pipe gallery 5 and the heating zone compressed air pipe gallery 6 are all laid out on high supports. Since the compensators for large-diameter compressed air pipes are expensive and prone to leaking media during operation, for high-temperature main process large-diameter pipes, such as the exhaust main pipes of each stage of compressors and the inlet main pipes of each cylinder of turbines, thermal compensation is achieved by using natural compensation bends to cross the factory roads, thereby reducing the number of compensators as much as possible. In addition, the space below the compressed air pipes can be defined to form an inspection and maintenance channel, further facilitating the movement of maintenance personnel.

[0049] Optionally, in this embodiment, the unit (closed or open) circulating cooling water pipeline is directly buried and arranged below the cooling zone compressed air corridor 5 and the heating zone compressed air corridor 6. This installation method can effectively save upper floor space, reduce the occupation of the ground or other facilities, optimize the overall equipment layout, and improve site utilization.

[0050] Optionally, in this embodiment, all heat exchangers in cooler zone 3 and heater zone 4 are arranged in a single layer, avoiding the need for a frame structure and effectively reducing the amount of civil engineering work and construction costs. Furthermore, in this embodiment, the heat exchangers in cooler zone 3 and heater zone 4, located near gas storage reservoir A, are high-pressure heat exchangers, while those located further away from gas storage reservoir A are low-pressure heat exchangers. This allows for the specific layout of the heat exchangers to be rationally planned based on the location of gas storage reservoir A, aligning the layout with the process flow and reducing the length of the high-pressure air piping.

[0051] Optionally, in this embodiment, the arrangement structure also includes a hot and cold water tank area 9 and an auxiliary facilities area 10. The main function of the hot and cold water tank area 9 is to provide heat exchange and temperature regulation functions to ensure heat management in different operating stages. In this embodiment, the hot and cold water tank area 9 is arranged on one side of the compressor room 1, and the auxiliary facilities area 10 is arranged in the hot and cold water tank area 9. Taking into account the large outdoor temperature difference, the auxiliary facilities area 10 is closed. In addition, the auxiliary facilities area 10 is connected to the heat storage cycle cooling water supply and return pipe 711 and the heat storage cycle heating water supply and return pipe 712, and includes an instrument compressed air preparation device, an instrument compressed air filter device, an instrument compressed air storage tank, a nitrogen preparation device, a nitrogen preparation drying and filtering device, a heat storage cycle water pump, an air compressor and a constant pressure make-up water pump, so that the auxiliary facilities area 10 can provide the necessary water source support for the heat storage cycle cooling water supply and return pipe 711 and the heat storage cycle heating water supply and return pipe 712 to ensure the balanced operation of the cooling and heating system.

[0052] Optionally, in this embodiment, the layout structure also includes a water area 101, which includes a circulating water pump room 1011, a fire water pump room 1012 and an industrial water pump room 1013. The circulating water pump room 1011, the industrial water pump room 1013 and the fire water pump room 1012 are independently set according to the water pump capacity, appearance, layout form and characteristics. This classified layout helps to simplify the layout, so that each pump room can be designed according to its specific function, reduce space waste, and achieve a more compact layout.

[0053] More specifically, in this embodiment, the water district 101 also includes a chemical water treatment plant 1014 and an industrial water tank 1015. The circulating water pump room 1011 is located near the hot and cold water tank area 9, and the chemical water treatment plant 1014 is located between the circulating water pump room 1011 and the industrial water tank 1015. The chemical water treatment plant 1014 can sterilize and filter the water in the industrial water tank 1015 to improve the water quality. During use, the circulating water pump room 1011 can use the softened water treated by the chemical water treatment plant 1014 as make-up water to replenish the thermal storage circulating water system in the hot and cold water tank area 9 for use.

[0054] Furthermore, a cooling tower area 1016 is arranged near the circulating water pump room 1011. The cooling tower area 1016 is used to cool the unit's cooling circulating water to prevent the circulating water temperature from being too high and having an adverse effect on the performance and efficiency of the compressed air energy storage unit.

[0055] Furthermore, a sewage treatment room 1017 is provided between the industrial water pool 1015 and the fire pump room, and a living area 102 and an office area 103 are arranged near the sewage treatment facilities. In this embodiment, the water area 101, the living area 102 and the office area 103 are all arranged near the water source area B to facilitate water quality treatment, water replenishment and water circulation, reduce the length of the pipeline, and facilitate the water source to directly provide directly usable water to the living area 102 and the office area 103. In addition, the sewage after use in the living area 102, the office area 103 and the fire pump room can flow directly to the sewage treatment room 1017 to realize direct management of the sewage. Moreover, since the living area 102, the office area 103 and the fire pump room are all arranged adjacent to the sewage treatment room 1017, the length of the pipeline between the living area 102, the office area 103 and the fire pump room and the sewage treatment room 1017 can be effectively shortened, and the phenomenon of pipeline crossing can be reduced, ensuring that the pipeline is smooth and short, which not only further improves the compactness of the layout of the structure, but also further reduces the cost of manufacturing and operation and maintenance.

[0056] Optionally, the layout structure provided in this embodiment also includes a spare parts room 1018, which is arranged at a corner of the layout structure and is mainly used to store spare parts, accessories and related tools for various equipment in the layout structure, so as to facilitate maintenance personnel to obtain required parts and shorten maintenance time. It can also effectively utilize the corner space of the layout structure, save the main operating space in the central area, and thus maximize the utilization of the layout structure space.

A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
