Description

Technical Field

[0001] This application relates to the field of gas turbine technology, specifically to a gas turbine power generation environment simulation device and its power generation system. Background Technology

[0002] Gas turbines are widely used in distributed energy stations, long-distance natural gas transmission, and chemical power due to their advantages such as simple structure, fast start-up, high power-to-weight ratio, long lifespan, and high energy efficiency. Generally, low inlet air pressure leads to a significant decrease in turbine efficiency; low inlet air temperature makes starting difficult; and high inlet humidity or water ingress can cause compressor surge. These phenomena demonstrate that changes in the inlet air state directly affect the turbine's safety, performance, and economy. It's easy to understand that different regions have different climatic conditions; for example, the climatic conditions (i.e., air states) differ significantly between plateaus and plains. If a gas turbine is suitable for power generation in plains, it cannot be directly used for power generation in plateau regions due to the significant changes in air states. Similarly, if a gas turbine is suitable for power generation in plateau regions, it cannot be directly used for power generation in plains. For example, a certain gas turbine has a power generation efficiency of 36% in plains, but its power generation efficiency drops to only 28% when it is directly applied to plateau regions.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] It should be noted that in the description of this application, the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0035] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0037] To address the technical problem in the background art that gas turbines are difficult to adapt to operating areas with different gas pressures, this application proposes a gas turbine power generation environment simulation device. It should be clear that since air pressure is the environmental factor that has the greatest impact on gas turbine operation, the gas turbine power generation environment simulation device may include an air compressor 2, an electric motor 3, a gas storage module 5, and a first generator 9. For example... Figure 1 As shown, the electric motor 3 drives the air compressor 2 to rotate, and the gas turbine 8 drives the first generator 9 to rotate and generate electricity. The input end of the gas storage module 5 is connected to the output end of the air compressor 2, and the output end of the gas storage module 5 is connected to the input end of the gas turbine 8 (i.e., the air inlet of the gas turbine in the background art).

[0038] When using, such as Figure 1 As shown, the air compressor 2 is first driven to rotate by the electric motor 3. Since the input end of the air storage module 5 is connected to the output end of the air compressor 2, the air compressor 2 can compress and store the external air 22 into the air storage module 5. Since the output end of the air storage module 5 is connected to the input end of the gas turbine 8, the air storage module 5 can simulate the air pressure of the environment when the gas turbine 8 is in operation by adjusting the air pressure at the output end of the air storage module 5.

[0039] In the embodiments of this application, the gas storage module 5 can be any device capable of storing compressed air, such as a gas storage cabinet or a gas storage tank. It should be noted that adjusting the air pressure at the output of the gas storage module 5 is a mature technology and will not be elaborated upon here. For example, some gas storage cabinets or gas storage tanks on the market have built-in functions for adjusting the gas output pressure, or a pressure regulating valve is installed at the output of the gas storage module 5 to adjust the gas output pressure.

[0040] In the embodiments of this application, there are no restrictions on the model and type of air compressor 2, as long as the maximum airflow capacity of air compressor 2 is greater than the air demand of gas turbine 8 when it is operating at its highest condition. For example, air compressor 2 can be a model with higher pressure and smaller volume, or a model with lower pressure and larger volume. Air compressor 2 can be any type among screw, piston, centrifugal, vane, and scroll compressors. Specifically, the selection principle for air compressor 2 can prioritize economic efficiency. For example, centrifugal compressors can be driven by electric motors, thus offering better economic efficiency; that is, in this embodiment, a centrifugal compressor can be used as air compressor 2.

[0041] It should be noted that the lower limit of air pressure in plateau areas is 50 kPa, while the air pressure in plains areas is approximately 110 kPa. To enable the gas storage module 5 to simulate air pressures under different application scenarios, in the embodiments of this application, the air pressure adjustment range at the output of the gas storage module 5 can be greater than or equal to 50 kPa and less than or equal to 110 kPa. Of course, a suitable air pressure adjustment range can also be selected according to other requirements.

[0042] It is important to note that if the capacity of the gas storage module 5 is too large, the manufacturing cost will be high, resulting in poor economic efficiency; if the capacity of the gas storage module 5 is too small, the air compressor 2 will need to operate continuously, thus affecting its lifespan. To reduce the manufacturing cost of the gas storage module 5 and eliminate the need for the air compressor 2 to operate continuously, the inventors, through extensive testing, have determined that the gas storage capacity of the gas storage module 5 can be greater than or equal to the gas turbine's intake volume for two minutes, and less than or equal to the gas turbine's intake volume for five minutes. This is easily understood: if the gas storage capacity of the gas storage module 5 is greater than or equal to the gas turbine's intake volume for two minutes, and less than or equal to the gas turbine's intake volume for five minutes, then the capacity of the gas storage module 5 is relatively small, meaning its manufacturing cost is lower, and the air compressor 2 does not need to operate continuously. In other words, after the air compressor 2 fills the gas storage module 5, it has sufficient time to rest.

[0043] To reduce the amount of airborne particulate matter entering the air compressor 2 or the air storage module 5, in one embodiment of this application, such as Figure 2As shown, an air filter 1 can also be installed at the input end of the air compressor 2. During use, the air filter 1 can filter particulate matter in the air 22, preventing it from entering the air compressor 2 or the air storage module 5. Furthermore, the air filter 1 can significantly reduce the noise of the air compressor 2 during air intake.

[0044] To prevent abnormal pressure increases at the output of air compressor 2, which could damage gas storage module 5 or gas turbine 8, in one embodiment of this application, the gas turbine power generation environment simulation device may further include a pressure relief valve 4. For example... Figure 3 As shown, the input end of the pressure relief valve 4 is connected to the output end of the air compressor 2, and the output end of the pressure relief valve 4 is connected to the input end of the air compressor 2. During use, if the pressure at the output end of the air compressor 2 rises abnormally, the pressure relief valve 4 will automatically open, allowing excess air to flow from the output end of the air compressor 2 to the input end, thus preventing the abnormal pressure rise at the output end of the air compressor 2 from damaging the gas storage module 5 or the gas turbine 8.

[0045] It is important to understand that the air temperature at the input of the gas turbine 8 also has a certain impact on its safety, performance, and economy. In order to simulate the air temperature at the input of the gas turbine 8 in different application scenarios, in one embodiment of this application, such as... Figures 1 to 4 As shown, a temperature regulation module 6 can also be provided at the output end of the gas storage module 5. The temperature regulation module 6 is used to adjust the air temperature at the output end of the gas storage module 5. In the embodiments of this application, the temperature regulation module 6 can be a heat exchanger. In use, if the air temperature output from the output end of the gas storage module 5 is high, it can be lowered by the heat exchanger; if the air temperature output from the output end of the gas storage module 5 is low, it can be raised by the heat exchanger.

[0046] It is important to note that artificially lowering the air temperature at the output of the gas storage module 5 to below 4°C is quite difficult. Therefore, in applications involving gas turbine performance research, this gas turbine power generation environment simulation device can be built in low-temperature regions to achieve a lower lower limit for the inlet air temperature. It is easy to understand that if the gas turbine power generation environment simulation device is built in a low-temperature region, only the output of the gas storage module 5 needs to have a heating function. In other words, in applications where the gas turbine power generation environment simulation device is located in low-temperature regions, the temperature regulation module 6 can be an electric heater with only a heating function.

[0047] It's important to note that the temperature regulation module 6 can have only heating functionality, meaning it doesn't need to have cooling functionality, but can still provide cooling capabilities. For example, in high-operational-condition gas turbine applications, the air compressor 2 has a high compression ratio, resulting in high compressed air temperatures. In such cases, the temperature regulation module 6 can be used to cool the compressed air. Cooling methods can include water cooling or air cooling, which are common methods and will not be elaborated upon here.

[0048] It is important to understand that the air humidity at the input of the gas turbine 8 also has a certain impact on its safety, performance, and economy. In order to simulate the air humidity at the input of the gas turbine 8 in different application scenarios, in one embodiment of this application, such as... Figures 1 to 4 As shown, the output end of the gas storage module 5 is also equipped with a humidity adjustment module 7, which is used to adjust the air humidity at the output end of the gas storage module 5.

[0049] In the embodiments of this application, the air humidity at the output end of the gas storage module 5 can be adjusted in any reasonable manner. For example, in one embodiment of this application, the humidity regulating module 7 can be a pipe, one end of which is connected to the output end of the steam turbine 13 (hereinafter referred to as the steam turbine 13), and the other end is connected to the output end of the gas storage module 5. In use, the pipe can guide part of the water vapor 18 output by the steam turbine 13 to the output end of the gas storage module 5, thereby adjusting the humidity of the air output from the gas storage module 5. In another embodiment of this application, the humidity regulating module 7 can also be a device capable of generating atomized water 19, for example, the humidity regulating module 7 can be an ultrasonic atomizer or a compressor atomizer, etc.

[0050] In the embodiments of this application, the operator can adjust the air pressure, temperature, and humidity at the output of the gas storage module 5 using the gas storage module 5, temperature regulation module 6, and humidity regulation module 7 based on their long-term experience. To enable the operator to accurately adjust the air pressure, temperature, and humidity at the output of the gas storage module 5 without requiring extensive experience, in one embodiment of this application, the gas turbine power generation environment simulation device may further include a pressure sensor, a temperature sensor, and a humidity sensor. These sensors are all located at the input of the gas turbine 8 (not shown in the figure). During use, the operator can precisely adjust the air pressure, temperature, and humidity at the output of the gas storage module 5 based on the pressure value displayed by the pressure sensor, the temperature value displayed by the temperature sensor, and the humidity value displayed by the humidity sensor.

[0051] It should be noted that the embodiments proposed in this application, by configuring pre-installed equipment such as air compressors and air storage modules, can adjust air pressure, air temperature, and air humidity to conduct experiments and obtain the impact of changes in air conditions on gas turbine performance. The air pressure can be adjusted to the level required for the gas turbine's optimal operating condition, thereby improving the gas turbine's application range and economic efficiency. The embodiments proposed in this application can prevent the problem of reduced gas turbine efficiency due to insufficient intake pressure, and by adjusting the output air pressure of the air storage module, the gas turbine can be adapted to use in regions with different environmental conditions. This device can adjust air pressure, air temperature, and air humidity to conduct experiments, providing experimental basis for the design modification and improvement of gas turbines.

[0052] It should be noted that the application scenarios of the gas turbine power generation environment simulation device proposed in this application are numerous, meaning that no limitations are placed on the application scenarios of the gas turbine power generation environment simulation device proposed in this application. For example, for a mature gas turbine (hereinafter referred to as a mature gas turbine), the gas turbine power generation environment simulation device can be used to test the combination of air pressure, temperature, and humidity when the mature gas turbine is in its optimal operating state (e.g., when the power generation efficiency reaches its maximum or the gas turbine can operate stably); or to explore its operating state in various environments. For a gas turbine under design (hereinafter referred to as a design gas turbine), the gas turbine power generation environment simulation device can be used to simulate the environmental conditions under which the design gas turbine will operate. The designer can then adjust the design of the design gas turbine based on its performance in the operating environment, so that the designed gas turbine can achieve its optimal operating state after completion. When facing the technical problem that gas turbines are difficult to adapt to operating areas with different air conditions, as described in one embodiment of a power generation system below, the gas turbine power generation environment simulation device can be used to adjust the air pressure, temperature, and humidity at the gas turbine inlet to meet its operating requirements, thereby enabling the gas turbine to achieve its optimal operating state. The application scenarios of the gas turbine power generation environment simulation device proposed in this application will not be listed and elaborated here.

[0053] It is important to note that air pressure is the most significant factor affecting the operating condition of a gas turbine. The gas turbine power generation environment simulation device proposed in this application, by configuring an air compressor and an air storage module, can adjust the air pressure to the level required for the optimal operating condition of the gas turbine. This device can prevent compressor overspeed problems caused by insufficient intake pressure, and by adjusting the output air pressure of the air storage module, it enables the gas turbine to adapt to use in regions with different pressure conditions.

[0054] Having described the gas turbine power generation environment simulation device proposed in the embodiments of this application, this application now proposes an embodiment of a power generation system. Specifically, the power generation system includes a gas turbine 8 and the gas turbine power generation environment simulation device proposed in any of the above embodiments.

[0055] The power generation system proposed in this application, by configuring an air compressor and an air storage module, can adjust the air pressure to the level required for the optimal operating condition of the gas turbine. That is, the power generation system can prevent compressor overspeed problems caused by insufficient intake pressure, and by adjusting the output air pressure of the air storage module, the gas turbine can be adapted to use in regions with different environmental conditions.

[0056] To further improve the power generation efficiency of the power generation system, the system may also include a heat exchanger 11, a cooling tower 12, a steam turbine 13, and a second generator 14. For example... Figure 4 As shown, the steam turbine 13 drives the second generator 14 to generate electricity, and the output end of the steam turbine 13 is connected to the cooling tower 12. The heat medium input end of the heat exchange device 11 is connected to the output end of the gas turbine 8, the refrigerant input end of the heat exchange device 11 is connected to the cooling tower 12, and the refrigerant output end of the heat exchange device 11 is connected to the input end of the steam turbine 13.

[0057] When using, such as Figure 4 As shown, the cooling water in cooling tower 12 exchanges heat with the high-temperature flue gas output from gas turbine 8 in heat exchange device 11. After heat exchange, the cooling water becomes steam, which drives steam turbine 13 to rotate. The rotating steam turbine 13 drives the second generator 14 to generate electricity. The steam that has done its work returns to cooling tower 12 from the output of steam turbine 13. It should be noted that the arrangement of heat exchange device 11, steam turbine 13, and second generator 14 enables the secondary utilization of the energy of the high-temperature flue gas discharged from gas turbine 8 to generate electricity, thereby improving the power generation efficiency of the power generation system. During long-term use, soft water 20 can be added to cooling tower 12 to prevent it from drying out. After heat exchange, the high-temperature flue gas becomes low-temperature exhaust gas 21 and is discharged from the heat medium output of heat exchange device 11.

[0058] It is important to understand that the heat exchange device 11 works by transferring heat to achieve heat exchange, thereby regulating the temperature of the two fluids (i.e., high-temperature flue gas and water). Specifically, the heat exchange device typically consists of two fluid channels: a heat transfer fluid channel and a coolant fluid channel. During operation, the heat transfer medium (e.g., high-temperature flue gas) enters the heat transfer fluid channel through the heat transfer medium inlet, and the coolant (e.g., water) enters the coolant fluid channel through the coolant inlet. As the coolant flows in the coolant fluid channel, it absorbs the heat energy from the heat transfer medium in the heat transfer fluid channel, thus increasing the temperature of the coolant and decreasing the temperature of the heat transfer medium. Furthermore, the coolant that has absorbed heat (e.g., water absorbing heat to convert into steam) is output from the coolant output of the heat exchange device; the heat transfer medium that has released heat (e.g., low-temperature exhaust gas) is output from the heat transfer medium output of the heat exchange device. In the embodiments of this application, the heat exchange device can be any device capable of achieving heat exchange between high-temperature flue gas and water. For example, the heat exchange device can be a heat exchanger or a waste heat boiler.

[0059] In the embodiments of this application, the electricity generated by the power generation system can be used in any suitable application scenario. For example, the electricity generated by the power generation system can be supplied to the industrial power grid 16 (i.e., a 380V power grid) or the high-voltage power grid 17. In the embodiments of this application, both the first generator 9 and the second generator 14 are capable of generating electricity. The electricity generated by the first generator 9 can be supplied to the high-voltage power grid 17, while the electricity generated by the second generator 14 can be supplied to the industrial power grid 16. In a specific embodiment of this application, the power generation system is used to supply power to the high-voltage power grid 17. The power generation system also includes a first transformer 10 and a second transformer 15. Figure 4 As shown, the input terminal of the first transformer 10 is electrically connected to the first generator 9, and the output terminal of the first transformer 10 is electrically connected to the high-voltage power grid 17. The input terminal of the second transformer 15 is electrically connected to the second generator 14, and the output terminal of the second transformer 15 is electrically connected to the high-voltage power grid 17. Transforming the power generated by the generator through transformers and then supplying it to the high-voltage power grid is a mature technology and will not be elaborated here.

[0060] Through testing and verification, a certain gas turbine, operating in a plain area (at an atmospheric pressure of 101 kPa), achieves a maximum power output of 25 MW and a power generation efficiency of 36% under normal conditions. When directly applied to a plateau area (at an atmospheric pressure of 70 kPa), the maximum power output under normal conditions is 17 MW, with a power generation efficiency of 28%. Using the gas turbine in conjunction with the gas turbine power generation environment simulation device proposed in this application, adjusting the air pressure at the gas turbine input to 101 kPa, the maximum power output of the gas turbine can be restored to 25 MW. After deducting the energy consumption added by equipment such as the air compressor, the overall power generation efficiency is 34.9%.

[0061] The power generation system proposed in this application, by configuring an air compressor and an air storage module, can adjust the air pressure to the level required for the optimal operating condition of the gas turbine. This device can prevent compressor overspeed problems caused by insufficient intake pressure. Furthermore, by adjusting the output air pressure of the air storage module, the gas turbine can be adapted to use in regions with different environmental conditions.

[0062] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
