The entire contents of the aforementioned Chinese patent applications are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of power generation equipment technology, specifically relating to a gas turbine generator set and a heat dissipation control method. Background Technology

[0004] With the continuous development of the global economy and the increasing demand for energy, the market demand for industrial gas turbines is also showing a rapid growth trend. In the industrial production sector, industrial gas turbines, with their efficient, stable, and reliable power output, have become the preferred power equipment for many enterprises. Industrial gas turbines are widely used in industrial production, oil and gas, and aviation fields due to their high efficiency and reliability, and market demand is gradually increasing.

[0005] However, in low-temperature environments, ice can easily form at the gas inlet of the gas turbine generator set. The ice layer can reduce the cross-sectional area of ​​the inlet, affecting the normal gas delivery volume and thus adversely affecting the normal operation of the gas turbine generator set.

[0006] Furthermore, the gas turbine generator sets in the relevant technologies include gas turbines, generators, and other devices, all of which are mounted on the same vehicle body. This results in a large load on the vehicle body, making the design and manufacturing requirements of the vehicle body more stringent. In addition, in order to simultaneously support all the devices of the gas turbine generator set, the width of the vehicle body needs to be made very large, which cannot meet the road transport regulations. Summary of the Invention

[0007] This application provides a gas turbine generator set, including: a gas turbine, a generator, and a lubrication system. The gas turbine is drivenly connected to the generator. The lubrication system includes a lubrication path and a first heat dissipation component. The lubrication path is used to supply lubricating oil to the gas turbine and the generator. The first heat dissipation component includes a first radiator, which is located at the gas inlet of the gas turbine generator set and communicates with the lubrication path so that the lubricating oil transported by the lubrication path enters the first radiator and dissipates heat to the gas inlet of the gas turbine generator set via the first radiator.

[0008] This application also provides a heat dissipation control method applied to the aforementioned gas turbine generator set. The lubrication path includes an oil tank, a first oil pump, and a first oil circuit. The first oil circuit includes a first main oil circuit, a second main oil circuit, a first branch oil circuit, and a second branch oil circuit. One end of the first main oil circuit is connected to the oil outlet of the oil tank. The first oil pump is located in the first main oil circuit. One end of each of the first branch oil circuit and the second branch oil circuit is connected to the other end of the first main oil circuit. The other end of each of the first branch oil circuit and the second branch oil circuit is connected to one end of the second main oil circuit. The other end of the second main oil circuit is connected to the oil tank. The oil inlet is connected; the gas turbine and the generator are respectively connected to the second main oil circuit; the first heat dissipation component is connected to the first branch oil circuit, and the lubrication system further includes a second heat dissipation component connected to the second branch oil circuit; the lubrication path further includes a first control valve and a second control valve, the first control valve being located in the first branch oil circuit and the second control valve being located in the second branch oil circuit; the heat dissipation control method includes: when the anti-icing mode is activated, controlling the first control valve to open, and the second control valve to reduce its opening or close, so as to increase the flow rate of lubricating oil in the first branch oil circuit.

[0009] This application embodiment also provides a gas turbine generator set, including: a gas turbine, a generator, a wind turbine unit, a first vehicle body, and a second vehicle body; the first vehicle body is provided with a gas turbine ventilation compartment and a generator ventilation compartment, the gas turbine is located in the gas turbine ventilation compartment, and the generator is located in the generator ventilation compartment; the second vehicle body is provided with a ventilation intake compartment and a gas turbine intake compartment, at least a portion of the wind turbine unit is located in the ventilation intake compartment, the wind turbine unit has a second air outlet and a third air outlet, the gas turbine intake compartment is connected to the gas turbine intake compartment through a first air pipe, the second air outlet is connected to the gas turbine ventilation compartment through a second air pipe, and the third air outlet is connected to the generator ventilation compartment through a third air pipe.

[0010] In this embodiment, lubricating oil can be supplied to the gas turbine and generator through the lubrication path of the lubrication system, so that the gas turbine and generator have good lubrication effect and ensure their normal operation. At the same time, the lubrication path can also deliver the lubricating oil that has absorbed the heat of the gas turbine and generator to the first heat dissipation component, and dissipate heat to the gas outlet of the gas turbine generator set through the first heat dissipation component, thereby raising the temperature of the gas outlet and thus playing an anti-icing effect in low-temperature environments, preventing ice formation at the gas outlet from affecting the normal gas delivery of the gas turbine.

[0011] In this embodiment, the gas turbine, generator, and other devices are carried on a first vehicle body, while the wind turbine and other devices are carried on a second vehicle body, achieving a dual-vehicle mounting system. This reduces the load on each vehicle body, lowers the design and manufacturing requirements, and also allows for a smaller vehicle width to comply with road transport regulations. Furthermore, when the gas turbine generator set is operating, gas needs to be supplied to the gas turbine, and ventilation is required for both the gas turbine and the generator. Based on this, the first vehicle body in this embodiment is provided with a gas turbine ventilation compartment and a generator ventilation compartment, and the second vehicle body can be provided with a ventilation intake compartment and a gas turbine intake compartment. Thus, the fan unit can connect the gas turbine intake compartment and the gas turbine intake port through a first air pipe to supply gas to the gas turbine, ensuring its normal operation. The fan unit can also connect the second outlet and the gas turbine ventilation compartment through a second air pipe to introduce gas into the gas turbine ventilation compartment, thereby ventilating the area around the gas turbine and achieving a cooling effect. Furthermore, the fan unit can connect the third outlet and the generator ventilation compartment through a third air pipe to introduce gas into the generator ventilation compartment, thereby ventilating the area around the generator and achieving a cooling effect.

Detailed Implementation

[0035] 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, 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.

[0036] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0037] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0038] Referring to Figures 1 to 14, this application discloses a gas turbine generator set, which includes a gas turbine 01, a generator 02, and a lubrication system 04. The gas turbine 01 is a power component that provides power to the generator 02 to drive its operation and generate electricity. The generator 02 converts kinetic energy into electrical energy to output electrical energy. The lubrication system 04 provides lubricating oil to at least the gas turbine 01 and generator 02, ensuring adequate lubrication, reducing wear, and guaranteeing the normal operation of the gas turbine 01 and generator 02.

[0039] The lubrication system 04 may include a lubrication path 10, in which components such as the gas turbine 01 and the generator 02 may be located. The lubrication path 10 supplies lubricating oil to the gas turbine 01 and the generator 02, thereby lubricating the components.

[0040] Considering that components such as gas turbine 01 and generator 02 can generate heat during operation, and that the lubricating oil absorbs some of the heat as it passes through these components, the lubricating oil can achieve a cooling effect on these components. At the same time, the temperature of the lubricating oil that absorbs heat is increased.

[0041] To dissipate heat from the lubricating oil, the lubrication system 04 may further include a first heat dissipation component 20, which includes a first radiator 21 connected to the lubrication path 10, allowing the lubricating oil transported by the lubrication path 10 to enter the first radiator 21. Based on this configuration, the heat in the lubricating oil can be dissipated through the first radiator 21 to obtain lubricating oil at a lower temperature, thereby continuing to lubricate and cool components such as the gas turbine 01 and the generator 02.

[0042] Considering that the gas inlet of the gas turbine generator set is prone to icing under some low-temperature conditions, the ice layer will reduce the cross-sectional area of ​​the gas inlet, affecting the normal gas supply of the gas turbine generator set, which will have an adverse impact on the normal operation of the gas turbine generator set.

[0043] Based on the above, in this embodiment of the application, the first radiator 21 can be placed near the gas inlet of the gas turbine generator set, so as to dissipate heat to the area where the gas inlet is located through the first radiator 21, thereby raising the temperature of the area and effectively alleviating the problem of icing at the gas inlet.

[0044] Based on the above configuration, in this embodiment, lubricating oil can be supplied to the gas turbine 01 and generator 02 through the lubrication path 10 of the lubrication system 04, so that the gas turbine 01 and generator 02 have good lubrication effect and ensure stable operation of the gas turbine 01 and generator 02. At the same time, the lubrication path 10 can also transport the lubricating oil that has absorbed the heat of the gas turbine 01 and generator 02 to the first heat dissipation component 20, and dissipate heat to the gas inlet of the gas turbine generator set through the first heat dissipation component 20, thereby raising the temperature in the area near the gas inlet, and thus playing an anti-icing role in low-temperature environments, preventing ice formation at the gas inlet from affecting the normal intake of the gas turbine generator set.

[0045] Referring to Figure 6, in some embodiments, the gas inlet of the gas turbine generator set may include a gas turbine inlet filter 0612 and at least one inlet filter 0614. The gas turbine inlet filter 0612 is used to supply gas to the surrounding environment of the gas turbine 01 to achieve ventilation of the environment around the gas turbine 01, which can, to a certain extent, cool the gas turbine 01. The inlet filter 0614 is used to supply gas to the interior of the gas turbine 01 to ensure the gas required for the operation of the gas turbine 01. It should be noted that both the gas turbine inlet filter 0612 and at least one inlet filter 0614 can be located on the side wall of the fan housing nacelle 061 of the auxiliary vehicle body described below.

[0046] To achieve the heating effect at each air inlet, the first heat dissipation component 20 may include a plurality of first radiators 21, as shown in Figure 6. The plurality of first radiators 21 are respectively located at the gas turbine air inlet filter 0612 and at least one air inlet filter 0614, and the plurality of first radiators 21 are respectively connected to the lubrication path 10.

[0047] Based on the above configuration, lubricating oil that absorbs heat from components such as the gas turbine 01 and generator 02 can be delivered to multiple first radiators 21 through the lubrication path 10. Heat can also be transferred to the corresponding gas turbine air inlet filter 0612 and at least one air inlet filter 0614 through the multiple first radiators 21. This can effectively prevent icing at the gas turbine air inlet filter 0612 and at least one air inlet filter 0614, ensuring normal ventilation and air intake of the gas turbine 01.

[0048] Optionally, as shown in Figure 6, the air intake filter 0614 may include a driver's side air intake filter, a passenger side air intake filter, and a rear side air intake filter. In addition, it may include air intake filters 0614 located in other positions. Thus, by setting the first radiator 21, it can be ensured that each air intake filter 0614 will not freeze, thereby ensuring smooth air intake and further ensuring sufficient air intake.

[0049] Referring again to Figure 6, in some embodiments, the gas inlet of the gas turbine generator set may further include a generator air inlet filter 0613, at which a first radiator 21 is provided, and the first radiator 21 is connected to the lubrication path 10. The generator air inlet filter 0613 is used to supply gas to the surrounding environment of the generator 02 to achieve ventilation of the environment around the generator 02, which can, to a certain extent, cool the generator 02.

[0050] Based on the above configuration, lubricating oil that absorbs heat from components such as the gas turbine 01 and generator 02 can be delivered to the first radiator 21 through the lubrication path 10, and heat can be transferred to the generator air inlet filter 0613 through the first radiator 21, thereby effectively preventing ice formation at the generator air inlet filter 0613 and ensuring normal ventilation of the generator 02.

[0051] Optionally, port filters 091 can be provided at each of the above-mentioned air inlet filter 0614, gas turbine air inlet filter 0612 and generator air inlet filter 0613 to filter the input gas and ensure the cleanliness of the gas.

[0052] Referring to Figure 9, in some embodiments, the first radiator 21 may include heat sinks 211 arranged in a labyrinth pattern. This arrangement increases the surface area of ​​the heat sinks 211, thereby further improving the heat dissipation efficiency of the first radiator 21. At the same time, designing the heat sinks 211 in a labyrinth pattern can also block sand and dust in windy and sandy environments, preventing sand and dust from entering the interior of the first radiator 21 and affecting its heat dissipation efficiency.

[0053] In some more specific embodiments, an inertial filter may be provided on the outside of the first radiator 21. The inertial filter can achieve the effect of inertial filtration of wind and sand, further alleviating the problem of wind and sand entering the interior of the first radiator 21 and affecting its heat dissipation efficiency.

[0054] To achieve power transmission, as shown in Figures 3 and 4, the gas turbine generator set may also include a gearbox 03, which is connected between the gas turbine 01 and the generator 02. In this way, during the operation of the gas turbine 01, the gearbox 03 can drive the gearbox 03 to move, and the gearbox 03 can drive the generator 02 to run, so as to generate electricity through the operation of the generator 02.

[0055] Optionally, gearbox 03 can be a gear-type reduction gearbox, etc.

[0056] Furthermore, the gearbox 03 can also be connected to the lubrication path 10 to supply lubricating oil to the gearbox 03 through the lubrication path 10 and to cool the gearbox 03.

[0057] Referring to Figure 1, in some embodiments, the lubrication path 10 may include an oil tank 11, a first oil pump 121, a second oil pump 122, a first oil passage 13, and a second oil passage 14. The inlet ends of the first oil passage 13 and the second oil passage 14 are respectively connected to the outlet of the oil tank 11, the outlet end of the first oil passage 13 is connected to the inlet of the oil tank 11, and the outlet end of the second oil passage 14 is connected to the first oil passage 13. The first oil pump 121 is located in the first oil passage 13, and the second oil pump 122 is located in the second oil passage 14. Furthermore, the gas turbine 01, the generator 02, and the gearbox 03 are respectively connected to the first oil passage 13 and are all located downstream of the junction of the second oil passage 14 and the first oil passage 13.

[0058] Based on the above configuration, under the action of the first oil pump 121, the lubricating oil in the oil tank 11 can enter the first oil passage 13 and flow from the inlet end to the outlet end of the first oil passage 13; under the action of the second oil pump 122, the lubricating oil in the oil tank 11 can enter the second oil passage 14 and flow into the first oil passage 13 through the outlet end of the second oil passage 14. Therefore, lubricating oil can be supplied to the gas turbine 01, generator 02, and gearbox 03 through the first oil passage 13, achieving lubrication of the gas turbine 01, generator 02, and gearbox 03, and also providing a cooling effect.

[0059] It should be noted that the first oil pump 121 can be the main oil pump, and the second oil pump 122 can be an auxiliary oil pump or an emergency oil pump. Under normal circumstances, the first oil pump 121 can be started to supply lubricating oil to the gas turbine 01, generator 02, and gearbox 03 through the first oil circuit 13, thereby achieving lubrication and cooling for the three components respectively. When the first oil pump 121 fails, the second oil pump 122 can be started to deliver lubricating oil to the first oil circuit 13 through the second oil circuit 14, and then supply lubricating oil to the gas turbine 01, generator 02, and gearbox 03 through the first oil circuit 13, thereby achieving lubrication and cooling for the three components respectively.

[0060] Of course, in other embodiments, in order to increase the supply flow of lubricating oil, the first oil pump 121 and the second oil pump 122 can also work together. In this case, the lubricating oil pumped by the first oil pump 121 and the lubricating oil pumped by the second oil pump 122 can merge in the first oil passage 13 and flow together to the gas turbine 01, the generator 02 and the gearbox 03 to provide lubrication and cooling for the three respectively.

[0061] To further improve the heat dissipation effect of the lubricating oil, the lubrication system 04 may also include a second heat dissipation component 30 arranged in parallel with the first heat dissipation component 20, so that the second heat dissipation component 30 and the first heat dissipation component 20 work together to achieve the heat dissipation effect of the lubricating oil and improve the heat dissipation efficiency.

[0062] The second heat dissipation component 30 may include a second radiator 31, as shown in Figures 1 and 5 to 8. The second radiator 31 is connected to the lubrication path 10. In this way, lubricating oil that absorbs heat can be delivered to the second radiator 31 through the lubrication path 10, and some of the heat in the lubricating oil can be dissipated to the outside through the second radiator 31, thereby achieving the heat dissipation effect of the lubricating oil and effectively preventing the lubricating oil from deteriorating due to excessive temperature and affecting the cooling effect on the gas turbine 01, generator 02 and gearbox 03.

[0063] For example, the second heat sink 31 may include heat dissipation fins to increase the heat dissipation area and improve heat dissipation efficiency.

[0064] Referring again to Figure 1, in some embodiments, the first oil passage 13 may include a first main oil passage 131, a second main oil passage 132, a first branch oil passage 133, and a second branch oil passage 134. One end of the first main oil passage 131 is connected to the oil outlet of the oil tank 11, and the first oil pump 121 is located in the first main oil passage 131. One end of each of the first branch oil passage 133 and the second branch oil passage 134 is connected to the other end of the first main oil passage 131, and the other end of each of the first branch oil passage 133 and the second branch oil passage 134 is connected to one end of the second main oil passage 132. The other end of the second main oil passage 132 is connected to the oil inlet of the oil tank 11. Based on this configuration, under the action of the first oil pump 121, the lubricating oil in the oil tank 11 can first flow into the first main oil passage 131, and then flow from the first main oil passage 131 into the first branch oil passage 133 and the second branch oil passage 134 respectively. Then, the first branch oil passage 133 and the second branch oil passage 134 converge into the second main oil passage 132, and finally flow back to the oil tank 11 through the second main oil passage 132, thus realizing the circulation of lubricating oil.

[0065] Furthermore, the oil outlet of the second oil passage 14 is connected to the second main oil passage 132, so that under the action of the second oil pump 122, the lubricating oil in the oil tank 11 can first flow into the second oil passage 14, and then flow into the second main oil passage 132 from the second oil passage 14, and finally flow back to the oil tank 11 through the second main oil passage 132, thereby realizing the circulation of lubricating oil.

[0066] The gas turbine 01, generator 02, and gearbox 03 can be connected to the second main oil circuit 132 respectively, so that lubricating oil can be supplied to the gas turbine 01, generator 02, and gearbox 03 respectively through the second main oil circuit 132, thereby achieving the lubrication and cooling of the three. After the lubricating oil in the gas turbine 01, generator 02, and gearbox 03 absorbs a certain amount of heat, it flows back to the oil tank 11 through the second main oil circuit 132, so that the heated lubricating oil can be reused in the future.

[0067] The first heat dissipation component 20 is connected to the first branch oil passage 133 to supply lubricating oil that has absorbed heat to the first heat dissipation component 20, and to dissipate heat from the lubricating oil through the first branch oil passage 133, thereby reducing the temperature of the lubricating oil. At the same time, the first heat dissipation component 20 can dissipate heat to the gas inlet of the gas turbine generator set to prevent icing at the gas inlet.

[0068] The second heat dissipation component 30 is connected to the second branch oil passage 134 to supply the lubricating oil that has absorbed heat to the second heat dissipation component 30, thereby dissipating heat from the lubricating oil and reducing its temperature.

[0069] Referring again to Figure 1, in some embodiments, the lubrication path 10 may further include a thermostat 15, which may include a first oil inlet port 151, a second oil inlet port 152, and an oil outlet port 153. The first oil inlet port 151 is connected to the other end of the first branch oil passage 133 and the second branch oil passage 134, the second oil inlet port 152 is connected to the first main oil passage 131 through a first connecting oil passage, and the oil outlet port 153 is connected to the second main oil passage 132.

[0070] Based on the above settings, when the temperature of the lubricating oil is relatively low (i.e., not exceeding the preset temperature), the first oil inlet port 151 of the thermostat 15 can be closed, and the second oil inlet port 152 can be opened, allowing the lubricating oil to flow into the thermostat 15 through the second oil inlet port 152 and be discharged directly through the oil outlet port 153 of the thermostat 15. During this process, the lubricating oil will not be affected by the heat dissipation effect of either the first heat dissipation component 20 or the second heat dissipation component 30, thereby effectively preventing the lubricating oil temperature from being too low and affecting the lubrication effect. It should be noted that the preset temperature is higher than the freezing temperature to prevent icing at the air inlet at this preset temperature.

[0071] When the temperature of the lubricating oil is relatively high (i.e., exceeds the preset temperature), the first oil inlet port 151 of the thermostat 15 opens and the second oil inlet port 152 closes, so that the lubricating oil enters from the first main oil passage 131 into the first branch oil passage 133 and the second branch oil passage 134. Thus, the lubricating oil can be cooled by the first heat dissipation component 20 and the second heat dissipation component 30 respectively, and the cooled lubricating oil is output through the oil outlet port 153, thereby effectively preventing the lubricating oil temperature from being too high and affecting the heat dissipation effect.

[0072] To further control the flow path of the lubricating oil, the lubrication path 10 may also include a first control valve 161 and a second control valve 162. The first control valve 161 is located in the first branch oil passage 133 and upstream of the first heat dissipation assembly 20; the second control valve 162 is located in the second branch oil passage 134 and upstream of the second heat dissipation assembly 30.

[0073] Based on the above settings, the first control valve 161 can control the on / off state of the first oil circuit 133 or the flow rate of the lubricating oil, and the second control valve 162 can control the on / off state of the second oil circuit 134 or the flow rate of the lubricating oil. In this way, the heat dissipation effect of the lubricating oil can be adjusted by controlling the on / off state and the flow rate to meet the heat dissipation requirements under different working conditions.

[0074] For example, when the ambient temperature of the gas turbine generator set is lower than a first low temperature value (e.g., -10 degrees Celsius), the gas inlet of the gas turbine generator set is prone to icing, requiring more heat to prevent icing. In this situation, the opening of the first control valve 161 can be adjusted to its maximum position, and the second control valve 162 can be closed, allowing a larger flow of lubricating oil into the first heat dissipation assembly 20. This enables the first heat dissipation assembly 20 to dissipate more heat to the gas inlet, effectively preventing icing at the gas inlet.

[0075] When the ambient temperature of the gas turbine generator set is between a first low temperature value and a second low temperature value (where the second low temperature value is higher than the first low temperature value, such as 0 degrees Celsius), the icing difficulty at the gas turbine generator set's air inlet is generally low. In this case, a significant amount of heat is required to prevent icing. Based on this situation, the opening of the first control valve 161 can be increased, and the opening of the second control valve 162 can be decreased to ensure a larger flow of lubricating oil into the first cooling assembly 20. This allows the first cooling assembly 20 to dissipate more heat to the air inlet, effectively preventing icing at the air inlet. Simultaneously, some lubricating oil flows into the second cooling assembly 30 for heat dissipation.

[0076] When the ambient temperature of the gas turbine generator set is higher than the second low temperature value, the gas inlet of the gas turbine generator set is less prone to icing. In this case, less heat is needed to prevent icing. Based on this, the opening of the first control valve 161 can be reduced, and the opening of the second control valve 162 can be increased to ensure a smaller flow of lubricating oil into the first cooling assembly 20. This allows the first cooling assembly 20 to dissipate less heat to the gas inlet, effectively preventing icing at the gas inlet. Simultaneously, some lubricating oil flows into the second cooling assembly 30 for heat dissipation.

[0077] Based on the above, the embodiments of this application can adaptively adjust the flow rate of lubricating oil flowing into the first heat dissipation component 20 according to the temperature of the environment where the gas turbine generator set is located, thereby ensuring that the first heat dissipation component 20 can provide sufficient heat at the gas inlet of the gas turbine generator set to prevent icing.

[0078] Referring to Figures 2 and 7, in some embodiments, the gas turbine generator set may further include a main vehicle body 05, an auxiliary vehicle body 06, and a wind turbine unit 07. The gas turbine 01 and generator 02 are both located on the main vehicle body 05, while the wind turbine unit 07 is located on the auxiliary vehicle body 06. Based on this configuration, the embodiments of this application employ a dual-vehicle load-bearing method with the main vehicle body 05 and the auxiliary vehicle body 06. Compared to a single-vehicle load-bearing method, the embodiments of this application can reduce the load on a single vehicle, thereby alleviating the problem of excessive axle load and effectively reducing the vehicle width to meet road transport regulations.

[0079] Considering that the gas turbine generator set requires the fan unit 07 to supply gas to the gas turbine 01 during operation, in this embodiment of the application, the gas supply port (011) of the gas turbine 01 and the first gas outlet of the fan unit 07 can be connected by the first gas pipe 081. In this way, the gas generated by the fan unit 07 can enter the gas turbine 01 through the first gas outlet, the first gas pipe 081 and the gas inlet of the gas turbine 01 in sequence to achieve gas supply and ensure the gas required for the operation of the gas turbine 01.

[0080] In addition, the gas turbine generator set requires a fan unit 07 to ventilate the gas turbine 01 and the generator 02 during operation. Based on this, in this embodiment, the main body 05 may have a gas turbine ventilation compartment 051 and a generator ventilation compartment 052, wherein the gas turbine ventilation compartment 051 is used to accommodate the gas turbine 01 and the generator ventilation compartment 052 is used to accommodate the generator 02.

[0081] Furthermore, the gas turbine ventilation compartment inlet 0511 and the second outlet of the fan unit 07 can be connected by the second air pipe 082. In this way, the gas generated by the fan unit 07 can enter the gas turbine ventilation compartment 051 through the second outlet, the second air pipe 082 and the gas turbine ventilation compartment inlet 0511 in sequence, so as to ventilate the gas turbine ventilation compartment 051 and meet the heat dissipation requirements of the gas turbine 01 in the gas turbine ventilation compartment 051.

[0082] The air inlet 0521 of the generator ventilation compartment and the third air outlet of the fan unit 07 can be connected by the third air pipe 083. In this way, the gas generated by the fan unit 07 can enter the generator ventilation compartment 052 through the third air outlet, the third air pipe 083 and the air inlet 0521 of the generator ventilation compartment in sequence, so as to ventilate the generator ventilation compartment 052 and meet the heat dissipation requirements of the generator 02 in the generator ventilation compartment 052.

[0083] It should be noted that the first, second, and third air outlets mentioned above can be independent of each other or they can be the same air outlet.

[0084] Optionally, the gas turbine ventilation compartment 051 may be provided with a gas turbine ventilation compartment air inlet 0511, and the generator ventilation compartment 052 may be provided with a generator ventilation compartment air inlet 0521; in addition, the auxiliary vehicle body 06 may be provided with an exhaust filter 0615 connected to the first exhaust port, a gas turbine exhaust filter 0616 connected to the second exhaust port, and a generator exhaust filter 0617 connected to the third exhaust port. Based on this, the first air outlet, the air outlet filter 0615, the first air pipe 081, and the air supply port 011 of the gas turbine 01 can be connected in sequence to supply air to the gas turbine 01; the second air outlet, the gas turbine air outlet filter 0616, the second air pipe 082, and the gas turbine ventilation compartment air inlet 0511 can be connected in sequence to dissipate heat from the gas turbine 01; the third air outlet, the generator air outlet filter 0617, the third air pipe 083, and the generator ventilation compartment air inlet 0521 can be connected in sequence to dissipate heat from the generator 02.

[0085] Optionally, the first air pipe 081, the second air pipe 082, and the third air pipe 083 can all be flexible hoses that can deform to adapt to the relative positions of the main vehicle body 05 and the auxiliary vehicle body 06.

[0086] Referring to Figure 7, in some embodiments, the auxiliary vehicle body 06 may have a fan housing 061, which is equipped with a partition 0611. The partition 0611 can divide the fan housing 061 into a first housing space and a second housing space arranged vertically. Additionally, the fan assembly 07 may include a first fan 071 and a second fan 072. The first fan 071 is located in the first housing space and is connected to a second air pipe 082. The second fan 072 is located in the second housing space and is connected to a third air pipe 083. Based on this arrangement, gas can be supplied to the gas turbine ventilation compartment 051 through the second air pipe 082 under the action of the first fan 071 to ventilate the gas turbine 01; and gas can be supplied to the generator ventilation compartment 052 through the third air pipe 083 under the action of the second fan 072 to ventilate the generator 02. In addition, arranging the first fan 071 and the second fan 072 in the vertical direction can make full use of the space in the height direction of the auxiliary vehicle body 06, which is beneficial to reducing the length of the auxiliary vehicle body 06.

[0087] Of course, the wind turbine unit 07 may also include a third wind turbine, which is used to supply gas to the gas turbine 01.

[0088] Referring to Figures 3 and 4, the main body 05 may also include a non-high-voltage engine compartment 053 and a high-voltage engine compartment 055 arranged along the length of the main body 05. The non-high-voltage engine compartment 053 may house medium-voltage and low-voltage electrical cabinets, while the high-voltage engine compartment 055 may house a high-voltage electrical cabinet. This arrangement separates the high-voltage electrical cabinet from the low-voltage and medium-voltage electrical cabinets, thereby preventing electrical injuries to maintenance personnel during operation. For example, the non-high-voltage engine compartment 053 and the high-voltage engine compartment 055 may be spaced apart along the length of the main body 05.

[0089] Referring to Figure 11, the auxiliary vehicle body 06 may also be equipped with a transformer compartment 062, which may contain a transformer cabinet. The transformer cabinet is connected to at least one of the low-voltage electrical cabinet, medium-voltage electrical cabinet and high-voltage electrical cabinet via cables to realize the transmission of electrical energy and signals.

[0090] In some embodiments, the gas turbine generator set may further include a gearbox 03 that drives between the gas turbine 01 and the generator 02, the gearbox 03 being located on the main body 05. Considering that at least a portion of the lubrication system 04 is located on the main body 05, the first heat dissipation assembly 20 may be located on the auxiliary body 06, and the lubrication path 10 extends to the auxiliary body 06 and connects to the first heat dissipation assembly 20. Based on this, lubricating oil can be delivered to the first heat dissipation assembly 20 located on the auxiliary body 06 via the lubrication path 10, so that heat can be dissipated to the gas inlet of the gas turbine generator set through the first heat dissipation assembly 20, thereby achieving an anti-icing effect. Exemplarily, structures such as the oil tank 11, the first oil pump 121, and the second oil pump 122 may be located on the main body 05, as shown in FIG3.

[0091] Optionally, the first main oil circuit 131 can extend from the main vehicle body 05 to the auxiliary vehicle body 06 and be connected to the first cooling component 20 via the first branch oil circuit 133 to deliver lubricating oil to the first cooling component 20.

[0092] In other embodiments, the second heat dissipation component 30 may be disposed on the auxiliary vehicle body 06. Correspondingly, the lubrication path 10 may be extended to the auxiliary vehicle body 06 and connected to the second heat dissipation component 30 to deliver lubricating oil to the second heat dissipation component 30 and dissipate heat from the lubricating oil through the second heat dissipation component 30.

[0093] In some embodiments, the two ends of the portion of the first main oil circuit 131 located between the main vehicle body 05 and the auxiliary vehicle body 06 can be connected to the main vehicle body 05 and the auxiliary vehicle body 06 respectively via quick-connect fittings.

[0094] As shown in Figures 5 to 8, the auxiliary vehicle body 06 may be equipped with a gooseneck 063, and the second heat dissipation component 30 may be located at the gooseneck 063, so that the second heat dissipation component 30 is exposed to the open environment. This can improve the heat dissipation efficiency of the second heat dissipation component 30 to a certain extent, and can also effectively utilize space and reduce the length of the auxiliary vehicle body 06. It should be noted that the end of the auxiliary vehicle body 06 may extend into a stepped structure, which can be regarded as the gooseneck 063.

[0095] In addition, a dual filter 092 may be provided on the gooseneck 063. The dual filter 092 is connected to the second main oil circuit 132 and is located downstream of the oil outlet port 153 of the thermostat 15.

[0096] Optionally, the first main oil passage 131 can extend from the main vehicle body 05 to the auxiliary vehicle body 06 and connect to the second cooling assembly 30 via the second branch oil passage 134 to deliver lubricating oil to the second cooling assembly 30.

[0097] Referring to Figure 10, in some embodiments, the main body 05 may include a load-bearing frame 054, which is composed of at least non-carbon steel beams and carbon steel beams. Based on this configuration, the load-bearing capacity of the main body 05 can be improved by using the load-bearing frame 054, and it also helps to reduce the weight of the load-bearing frame 054, reducing the risk of overweight. Compared with welded carbon steel frames in related technologies, it has the advantage of lightweighting while ensuring load-bearing capacity.

[0098] In addition to the above structure, the lubrication path 10 may also include an oil circuit temperature sensor 1321, a pressure sensor 1322, a level gauge 111, an oil tank differential pressure sensor 114, an electric heater 112, an oil tank temperature sensor 113, an oil mist remover 115, a check valve 163, etc., as shown in Figure 10.

[0099] Additionally, the lubrication path 10 may also include a pressure regulating valve 164 connected to a pressure regulating oil circuit. One end of the pressure regulating oil circuit is connected to the oil tank 11, and the other end is connected to the first main oil circuit 131. The pressure regulating valve is also connected to the second main oil circuit 132. Based on this configuration, when the oil pressure in at least one of the first main oil circuit 131 and the second main oil circuit 132 is too high, the pressure regulating valve 164 can open, allowing the lubricating oil in at least one of the first main oil circuit 131 and the second main oil circuit 132 to flow back to the oil tank 11 through the pressure regulating oil circuit.

[0100] In this embodiment of the application, the gas turbine generator set includes multiple operating modes, specifically:

[0101] In the case of a cold start of the gas turbine generator set, the lubricating oil is heated by an electric heater in the oil tank 11 to reach the required start-up temperature of the gas turbine. When the gas turbine generator set starts, the first oil pump 121 starts working in advance. At this time, the lubricating oil temperature has not reached the opening temperature of the thermostat 15, so the lubricating oil does not pass through the first radiator 21 and the second radiator 31, but flows through the thermostat 15 and into the gas turbine 01, generator 02 and gearbox 03 respectively, and finally flows back to the oil tank 11. The specific path is shown in Figure 11.

[0102] Once the lubricating oil reaches the opening temperature of the thermostat 15, and without needing to activate the anti-icing mode, the first control valve 161 is closed and the second control valve 162 is opened. Under the action of the first oil pump 121, the lubricating oil can flow into the second radiator 31 via the second branch oil passage 134 to dissipate heat from the lubricating oil. After cooling, the lubricating oil flows through the thermostat 15 and then into the gas turbine 01, generator 02, and gearbox 03, and finally returns to the oil tank 11. The specific path is shown in Figure 12.

[0103] When the ambient temperature is very low and the anti-icing mode needs to be activated, the first control valve 161 is opened and the second control valve 162 is closed. Under the action of the first oil pump 121, the lubricating oil can flow into the first radiator 21 through the first branch oil line 133, so as to dissipate heat to each gas inlet of the gas turbine generator set through the first radiator 21, thereby effectively preventing ice formation and blockage at each gas inlet. The specific path is shown in Figure 13.

[0104] Despite the low ambient temperature, the high power output of the gas turbine 01, generator 02, and gearbox 03 may generate significant heat, leading to a higher lubricating oil temperature and hindering heat dissipation. To address this, the first control valve 161 and the second control valve 162 can be opened simultaneously. Under the action of the first oil pump 121, a portion of the lubricating oil can flow into the first radiator 21 via the first oil line 133, dissipating heat to the various gas inlets of the gas turbine generator set and preventing icing. Another portion of the lubricating oil can flow into the second radiator 31 via the second oil line 134, further cooling the lubricating oil. The specific path is shown in Figure 14.

[0105] Based on the above-described gas turbine generator set, this application also discloses a heat dissipation control method applied to the gas turbine generator set. Referring to Figures 1 to 14, the gas turbine generator set may include a gas turbine 01, a generator 02, and a lubrication system 04. The lubrication system 04 includes a lubrication path 10, a first heat dissipation component 20, and a second heat dissipation component 30.

[0106] The lubrication path 10 includes an oil tank 11, a first oil pump 121, and a first oil passage 13. The first oil passage 13 includes a first main oil passage 131, a second main oil passage 132, and a second branch oil passage 134. One end of the first main oil passage 131 is connected to the oil outlet of the oil tank 11, and the first oil pump 121 is located in the first main oil passage 131. One end of each of the first branch oil passage 133 and the second branch oil passage 134 is connected to the other end of the first main oil passage 131, and the other end of each of the first branch oil passage 133 and the second branch oil passage 134 is connected to one end of the second main oil passage 132. The other end of the second main oil passage 132 is connected to the oil inlet of the oil tank 11. The gas turbine 01 and the generator 02 are respectively connected to the second main oil passage 132.

[0107] Based on the above configuration, under the action of the first oil pump 121, the lubricating oil in the oil tank 11 can be output through the first main oil passage 131 and flow into the first branch oil passage 133 and the second branch oil passage 134 respectively. The first branch oil passage 133 and the second branch oil passage 134 then collect the lubricating oil into the second main oil passage 132, and deliver it to the gas turbine 01 and the generator 02 respectively through the second main oil passage 132 to achieve lubrication and cooling of the gas turbine 01 and the generator 02. The lubricating oil after passing through the gas turbine 01 and the generator 02 flows back to the oil tank 11.

[0108] Furthermore, the first heat dissipation component 20 is connected to the first branch oil passage 133, and the second heat dissipation component 30 is connected to the second branch oil passage 134. Based on this configuration, the heat of the lubricating oil in the first branch oil passage 133 can be dissipated through the first heat dissipation component 20, and the heat of the lubricating oil in the second branch oil passage 134 can be dissipated through the second heat dissipation component 30.

[0109] Considering that the first heat dissipation component 20 is located at the gas inlet of the gas turbine generator set, the temperature at the gas inlet can be increased, thereby effectively alleviating the problem of icing at the gas inlet.

[0110] To control the flow rate of lubricating oil, the lubrication path 10 may further include a first control valve 161 and a second control valve 162. The first control valve 161 is located in the first branch oil passage 133, and the second control valve 162 is located in the second branch oil passage 134. Thus, the flow rate of lubricating oil in the first branch oil passage 133 can be controlled by the first control valve 161, and the flow rate of lubricating oil in the second branch oil passage 134 can be controlled by the second control valve 162. This ensures that the first heat dissipation component 20 can dissipate sufficient heat to the gas inlet of the gas turbine generator set, effectively preventing icing.

[0111] Based on the above settings, the heat dissipation control method in this application embodiment includes:

[0112] When the anti-icing mode is activated, the first control valve 161 is opened and the second control valve 162 is closed or reduced in opening, so as to increase the flow rate of lubricating oil in the first branch oil circuit 133, thereby increasing the amount of lubricating oil flowing into the first heat dissipation component 20, so that the first heat dissipation component 20 can dissipate more heat to the gas inlet of the gas turbine generator set, thus playing a role in preventing icing.

[0113] In some embodiments, the gas turbine generator set may further include a temperature sensing element 0101 for detecting ambient temperature and a humidity sensing element 0102 for detecting ambient humidity. Exemplarily, the temperature sensing element 0101 may be a temperature sensor and the humidity sensing element 0102 may be a humidity sensor.

[0114] The heat dissipation control method includes: determining that the anti-icing mode needs to be activated when the ambient temperature detected by the temperature detection element 0101 is lower than the preset temperature and the ambient humidity detected by the humidity detection element 0102 is higher than the preset humidity.

[0115] It should be noted that by real-time monitoring of ambient temperature and humidity, it is determined whether the conditions for icing have been met. That is, when the ambient temperature is lower than the preset temperature and the ambient humidity is higher than the preset humidity, the conditions for icing are met. At this time, the gas turbine generator set can be activated in anti-icing mode to prevent ice from forming at the gas inlet of the gas turbine generator set, which would affect the intake or ventilation volume.

[0116] In some embodiments, the gas turbine generator set may further include a differential pressure detection element 0103 for detecting a first differential pressure between the gas turbine 01 inlet and ambient pressure, a second differential pressure between the gas turbine ventilation compartment and ambient pressure, and a third differential pressure between the generator ventilation compartment and ambient pressure.

[0117] In this embodiment of the application, the heat dissipation control method includes: when at least one of the first differential pressure, the second differential pressure, and the third differential pressure exceeds a set differential pressure value, determining that ice blockage has occurred at the gas inlet of the gas turbine generator set, and correspondingly controlling the first control valve 161 and the second control valve 162 to adjust their openings until the first differential pressure, the second differential pressure, and the third differential pressure all do not exceed the set differential pressure value.

[0118] It should be noted that when ice blockage occurs, the opening of the first control valve 161 needs to be increased, and the opening of the second control valve 162 needs to be decreased or closed, so that more lubricating oil can enter the first heat dissipation component 20, thereby enabling the first heat dissipation component 20 to dissipate more heat to the gas inlet of the gas turbine generator set, so as to achieve the purpose of de-icing.

[0119] In summary, the embodiments of this application can dissipate heat from each gas inlet of the gas turbine generator set through the first heat dissipation component 20 and the second heat dissipation component 30, so as to prevent the gas inlets from freezing and affecting the normal operation of the gas turbine generator set; the heat sink 211 is designed in a labyrinth form to block external wind and sand from entering.

[0120] The dual-vehicle configuration of the main body 05 and the auxiliary body 06 effectively alleviates the problem of excessive vehicle load. The main body 05 uses a load-bearing frame 054 that combines non-carbon steel and carbon steel, which ensures load-bearing strength while reducing weight to avoid the risk of overweight. The gas turbine generator set shares a lubrication system 04 and uses a supply method that coordinates the first oil pump 121 and the second oil pump 122 to ensure continuous operation of the gas turbine generator set without shutdown due to failure of the first oil pump 121. The first fan 071 for ventilating the gas turbine 01 and the second fan 072 for ventilating the generator 02 share a compartment and are arranged in an upper and lower layer. This arrangement minimizes the length of the auxiliary body 06 while meeting the ventilation requirements of the gas turbine 01 and the generator 02.

[0121] It should be noted that in any of the above embodiments of this application, the main vehicle body may also be referred to as the first vehicle body, the auxiliary vehicle body may also be referred to as the second vehicle body, and the wind turbine housing nacelle may also be referred to as the air intake nacelle.

[0122] Referring to Figures 15 to 22, this application discloses a gas turbine generator set, which includes a gas turbine 01, a generator 02, a wind turbine unit 07, a first vehicle body 05, and a second vehicle body 06. The gas turbine 01 is a power component that provides power to the generator 02 to drive its operation and generate electricity. The generator 02 converts kinetic energy into electrical energy to output electrical energy. The wind turbine unit 07 supplies gas to the gas turbine 01 and the generator 02 to meet their respective operating requirements.

[0123] Referring to Figures 16 and 17, the first vehicle body 05 may be equipped with a gas turbine ventilation compartment 051 and a generator ventilation compartment 052, wherein the gas turbine 01 is located in the gas turbine ventilation compartment 051 and the generator 02 is located in the generator ventilation compartment 052. Based on this, the first vehicle body 05 can support the gas turbine 01 and the generator 02, and the gas turbine 01 can be ventilated through the gas turbine ventilation compartment 051, while the generator 02 can be ventilated through the generator ventilation compartment 052.

[0124] The second vehicle body 06 may be equipped with a ventilation intake compartment 061a and a gas turbine intake compartment 061b. At least a portion of the wind turbine assembly 07 is located in the ventilation intake compartment 061a, so that the second vehicle body 06 can support at least a portion of the wind turbine assembly 07. The wind turbine assembly 07 may have a second air outlet and a third air outlet. The gas turbine intake compartment 061b is connected to the air inlet of the gas turbine 01 via a first air pipe 081, the second air outlet is connected to the gas turbine ventilation compartment 051 via a second air pipe 082, and the third air outlet is connected to the generator ventilation compartment 052 via a third air pipe 083.

[0125] Based on the above configuration, gas can sequentially enter the gas turbine 01 through the gas turbine inlet compartment 061b, the first gas pipe 081, and the gas turbine 01 inlet to ensure gas supply and guarantee the gas required for the operation of the gas turbine 01. The gas generated by the fan unit 07 can sequentially enter the gas turbine ventilation compartment 051 through the second outlet and the second gas pipe 082 to ventilate the gas turbine ventilation compartment 051 and meet the heat dissipation requirements of the gas turbine 01 in the gas turbine ventilation compartment 051. The gas generated by the fan unit 07 can also sequentially enter the generator ventilation compartment 052 through the third outlet and the third gas pipe 083 to ventilate the generator ventilation compartment 052 and meet the heat dissipation requirements of the generator 02 in the generator ventilation compartment 052.

[0126] In this embodiment, the gas turbine 01, generator 02 and other devices are carried by the first vehicle body 05, and the wind turbine 07 and other devices are carried by the second vehicle body 06, thereby realizing the dual-vehicle loading method of the first vehicle body 05 and the second vehicle body 06. This can reduce the load of each vehicle body, reduce the design and manufacturing requirements of the vehicle body, and also reduce the width of the vehicle body to comply with road transport regulations.

[0127] Referring to Figures 19 and 20, in some embodiments, the second vehicle body 06 may be provided with an air intake compartment 061, and the fan unit 07 may be located within the air intake compartment 061, so as to accommodate and install the fan unit 07 through the air intake compartment 061. The air intake compartment 061 may be a single unit or may include multiple independent sub-compartments, depending on the actual working conditions.

[0128] In some embodiments, the main air intake compartment 061 can be divided into a ventilation air intake compartment 061a and a gas turbine air intake compartment 061b. The gas turbine air intake compartment 061b may have an exhaust filter port 0615, and the ventilation air intake compartment 061a may have a gas turbine exhaust filter port 0616 and a generator exhaust filter port 0617. The exhaust filter port 0615 is connected to a first air pipe 081, the gas turbine exhaust filter port 0616 is connected to a second exhaust port and a second air pipe 082, and the generator exhaust filter port 0617 is connected to a third exhaust port and a third air pipe 083.

[0129] Based on the above configuration, the exhaust filter 0615, the first air pipe 081, and the gas turbine 01 can be connected in sequence to supply air to the gas turbine 01; the second exhaust port, the gas turbine exhaust filter 0616, the second air pipe 082, and the gas turbine ventilation compartment 051 can be connected in sequence to dissipate heat from the gas turbine 01; and the third exhaust port, the generator exhaust filter 0617, the third air pipe 083, and the generator ventilation compartment 052 can be connected in sequence to dissipate heat from the generator 02.

[0130] Optionally, the first air pipe 081, the second air pipe 082, and the third air pipe 083 can all be flexible tubes that can deform to adapt to the relative positions of the first vehicle body 05 and the second vehicle body 06.

[0131] Referring again to Figure 20, in some embodiments, a partition 0611 is provided inside the ventilation intake chamber 061a, which can divide the ventilation intake chamber 061a into a first accommodating space 0611a and a second accommodating space 0611b arranged vertically.

[0132] Additionally, the fan unit 07 may include a first fan 071 and a second fan 072. The first fan 071 is located in the first accommodating space 0611a and has a second air outlet; the second fan 072 is located in the second accommodating space 0611b and has a third air outlet.

[0133] Based on the above configuration, gas can be supplied to the gas turbine ventilation compartment 051 through the second outlet and the second air pipe 082 under the action of the first fan 071, thereby ventilating the gas turbine 01; and gas can be supplied to the generator ventilation compartment 052 through the third outlet and the third air pipe 083 under the action of the second fan 072, thereby ventilating the generator 02. Furthermore, arranging the first fan 071 and the second fan 072 vertically allows for full utilization of the space in the height direction of the second vehicle body 06, which is beneficial for reducing the length of the second vehicle body 06.

[0134] In some embodiments, the fan unit 07 may further include a third fan disposed within the gas turbine inlet compartment 061b, the third fan having a first outlet connected to a first gas pipe 081. Based on this arrangement, under the action of the third fan, gas is supplied to the gas turbine 01 through the first outlet and the first gas pipe 081, thereby achieving gas supply to the gas turbine 01.

[0135] Referring to Figures 16 and 22, in some embodiments, the gas turbine generator set may further include a lubrication path 04, at least a portion of which is located on the first vehicle body 05, for supplying lubricating oil to the gas turbine 01 and the generator 02 to achieve lubrication and cooling of the gas turbine 01 and the generator 02.

[0136] Considering that components such as gas turbine 01 and generator 02 can generate heat during operation, and that the lubricating oil absorbs some of the heat as it passes through these components, the lubricating oil can achieve a cooling effect on these components. At the same time, the temperature of the lubricating oil that absorbs heat is increased.

[0137] To achieve heat dissipation of the lubricating oil, as shown in Figure 22, the lubrication path 04 may further include a first heat dissipation component 20. This first heat dissipation component 20 is located on the second vehicle body 06 and connected to the lubrication path 04, allowing the lubricating oil transported by the lubrication path 04 to enter and be cooled by the first heat dissipation component 20. Based on this configuration, the heat in the lubricating oil is dissipated through the first heat dissipation component 20, resulting in lubricating oil with a lower temperature, thus enabling continued lubrication and cooling of components such as the gas turbine 01 and generator 02. Optionally, the first heat dissipation component 20 may include a first radiator.

[0138] Considering that the gas inlet of the gas turbine generator set is prone to icing under some low-temperature conditions, the ice layer will reduce the cross-sectional area of ​​the gas inlet, affecting the normal gas supply of the gas turbine generator set, which will have an adverse impact on the normal operation of the gas turbine generator set.

[0139] Based on the above, in this embodiment of the application, the first heat dissipation component 20 can be installed at the gas inlet of the gas turbine generator set, so as to dissipate heat to the area where the gas inlet is located through the first heat dissipation component 20, thereby raising the temperature of the area and effectively alleviating the problem of icing at the gas inlet.

[0140] Referring to Figures 19 and 20, in some embodiments, the gas turbine generator set's air inlet may include an air inlet filter 0614 located in the gas turbine air inlet compartment 061b, and a gas turbine air inlet filter 0612 and a generator air inlet filter 0613 located in the ventilation air inlet compartment 061a. The first heat dissipation component 20 is located at the air inlet filter 0614, the gas turbine air inlet filter 0612, and the generator air inlet filter 0613. Specifically, the gas can enter the gas turbine intake compartment 061b through the air intake filter port 0614, so that the gas can be subsequently delivered to the gas turbine 01 to ensure the gas required for the operation of the gas turbine 01; the gas can enter the ventilation intake compartment 061a through the gas turbine air intake filter port 0612, so that the gas can be subsequently delivered to the area around the gas turbine 01 to ventilate the environment around the gas turbine 01, which can cool the gas turbine 01 to a certain extent; the gas can enter the ventilation intake compartment 061a through the generator air intake filter port 0613, so that the gas can be subsequently delivered to the area around the generator 02 to ventilate the environment around the generator 02, which can cool the generator 02 to a certain extent.

[0141] In this embodiment, by placing the first heat dissipation component 20 at the air inlet filter 0614, the gas turbine air inlet filter 0612, and the generator air inlet filter 0613, the heat from the lubricating oil with a certain temperature transferred to the first heat dissipation component 20 via the heat dissipation path 10 can be diffused to the air inlet filter 0614, the gas turbine air inlet filter 0612, and the generator air inlet filter 0613 respectively. This effectively prevents air from merging at the air inlet filter 0614, the gas turbine air inlet filter 0612, and the generator air inlet filter 0613, ensuring normal air intake and ventilation of the gas turbine 01 and normal ventilation of the generator 02.

[0142] Referring again to Figure 22, in some embodiments, the lubrication path 04 may include an oil tank 11, a first oil pump 121, a second oil pump 122, a first oil passage 13, and a second oil passage 14. The inlet ends of the first oil passage 13 and the second oil passage 14 are respectively connected to the outlet of the oil tank 11, the outlet end of the first oil passage 13 is connected to the inlet of the oil tank 11, and the outlet end of the second oil passage 14 is connected to the first oil passage 13. At least a portion of the first oil passage 13 extends to the second vehicle body 06 and is connected to the first cooling assembly 20. Components such as the gas turbine 01 and the generator 02 can be connected to the first oil passage 13, and are all located downstream of the junction of the second oil passage 14 and the first oil passage 13. Furthermore, the first oil pump 121 is located on the first vehicle body 05 and connected to the first oil passage 13, and the second oil pump 122 is located on the first vehicle body 05 and connected to the second oil passage 14.

[0143] Based on the above configuration, under the action of the first oil pump 121, the lubricating oil in the oil tank 11 can enter the first oil passage 13 and flow from the inlet end to the outlet end of the first oil passage 13; under the action of the second oil pump 122, the lubricating oil in the oil tank 11 can enter the second oil passage 14 and flow into the first oil passage 13 through the outlet end of the second oil passage 14. Therefore, lubricating oil can be supplied to components such as the gas turbine 01 and the generator 02 through the first oil passage 13, achieving lubrication of these components and also providing a cooling effect.

[0144] It should be noted that the first oil pump 121 can be the main oil pump, and the second oil pump 122 can be an auxiliary oil pump or an emergency oil pump. Under normal circumstances, the first oil pump 121 can be started to supply lubricating oil to components such as the gas turbine 01 and the generator 02 through the first oil circuit 13, thereby achieving lubrication and cooling for the three components respectively. When the first oil pump 121 fails, the second oil pump 122 can be started to deliver lubricating oil to the first oil circuit 13 through the second oil circuit 14, and then supply lubricating oil to components such as the gas turbine 01 and the generator 02 through the first oil circuit 13, thereby achieving lubrication and cooling for both components respectively.

[0145] Of course, in other embodiments, in order to increase the supply flow of lubricating oil, the first oil pump 121 and the second oil pump 122 can also work together. In this case, the lubricating oil pumped by the first oil pump 121 and the lubricating oil pumped by the second oil pump 122 can merge in the first oil passage 13 and flow together to the gas turbine 01 and the generator 02 and other components, so as to lubricate and cool them respectively.

[0146] To further improve the cooling effect on the lubricating oil, the gas turbine generator set may also include a second cooling component 30, so that the second cooling component 30 and the first cooling component 20 work together to achieve the cooling effect on the lubricating oil and improve the cooling efficiency.

[0147] The second heat dissipation component 30 can be disposed on the second vehicle body 06, and a portion of the lubrication path 04 extends to the second vehicle body 06 and connects to the second heat dissipation component 30. Based on this, lubricating oil that absorbs heat can be supplied to the second heat dissipation component 30 through the lubrication path 04, and the second heat dissipation component 30 can dissipate some of the heat from the lubricating oil, achieving a heat dissipation effect on the lubricating oil and effectively preventing the lubricating oil from overheating and deteriorating, as well as affecting the cooling effect on components such as the gas turbine 01 and the generator 02. Optionally, the second heat dissipation component 30 may include a second radiator.

[0148] Optionally, the second heat dissipation component 30 and the first heat dissipation component 20 can be connected in parallel.

[0149] Optionally, the first oil circuit 13 may include two branch oil circuits, one of which is connected to the first heat dissipation component 20 and the other is connected to the second heat dissipation component 30. One branch oil circuit is provided with a first control valve 161 and the other branch oil circuit is provided with a second control valve 162, so as to control the lubricating oil flowing into the first heat dissipation component 20 and the second heat dissipation component 30 through the cooperation of the first control valve 161 and the second control valve 162.

[0150] In addition, the oil outlets of the two branch oil circuits can be connected to thermostats 15 to adjust the lubricating oil in the first heat dissipation assembly 20 and the second heat dissipation assembly 30 according to the thermostats 15.

[0151] To achieve power transmission, the gas turbine generator set may also include a gearbox 03, which is located on the first vehicle body 05 and is connected to the gas turbine 01 and the generator 02. In this way, during the operation of the gas turbine 01, the gearbox 03 can be driven to move, and the gearbox 03 can drive the generator 02 to operate, so as to generate electricity through the operation of the generator 02.

[0152] Optionally, gearbox 03 can be a gear-type reduction gearbox, etc.

[0153] Furthermore, the gearbox 03 can also be connected to the lubrication path 04 to supply lubricating oil to the gearbox 03 through the lubrication path 04 and to cool the gearbox 03.

[0154] Referring to Figures 16 and 17, in some embodiments, the first vehicle body 05 may further include a non-high-voltage engine compartment 053 and a high-voltage engine compartment 055 arranged along the length of the first vehicle body 05. The non-high-voltage engine compartment 053 may contain medium-voltage and low-voltage electrical cabinets, while the high-voltage engine compartment 055 contains a high-voltage electrical cabinet. This arrangement separates the high-voltage electrical cabinet from the low-voltage and medium-voltage electrical cabinets, thereby preventing electrical injuries to maintenance personnel during operation. For example, the non-high-voltage engine compartment 053 and the high-voltage engine compartment 055 may be spaced apart along the length of the first vehicle body 05.

[0155] It should be noted that the voltage of the high-voltage electrical cabinet is higher than that of the medium-voltage electrical cabinet, and the voltage of the medium-voltage electrical cabinet is higher than that of the low-voltage electrical cabinet. The high-voltage electrical cabinet, medium-voltage electrical cabinet and low-voltage electrical cabinet in the embodiments of this application are intended to indicate the relative voltage between each electrical cabinet, and do not represent that the voltage of each electrical cabinet is absolutely high voltage, medium voltage and low voltage respectively.

[0156] In some embodiments, the voltage corresponding to the high-voltage electrical cabinet can be higher than 35KV, the voltage corresponding to the medium-voltage electrical cabinet can be higher than 1KV and lower than 35KV, and the voltage corresponding to the low-voltage electrical cabinet can be lower than 1KV. Of course, other forms are also possible, and no specific limitation is made here.

[0157] In addition, as shown in Figures 19 and 20, the second vehicle body 06 may also be provided with a transformer compartment 062, which may be equipped with a transformer cabinet. The transformer cabinet is connected to at least one of the low-voltage electrical cabinet, medium-voltage electrical cabinet and high-voltage electrical cabinet via cables to realize the transmission of electrical energy and signals.

[0158] Referring to Figure 21, in some embodiments, the first vehicle body 05 may employ a load-bearing frame, which is at least composed of non-carbon steel beams and carbon steel beams. Based on this configuration, the load-bearing capacity of the first vehicle body 05 can be improved using a load-bearing frame, and it also helps to reduce the weight of the load-bearing frame, lowering the risk of overweight. Compared to welded carbon steel frames in related technologies, it has the advantage of lightweighting while ensuring load-bearing capacity.
