DETAILED DESCRIPTION

[0010] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0011] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0012] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0013] refer to Figures 1 to 14 The embodiment of the present application discloses a gas turbine generator set, and the disclosed gas turbine generator set includes a gas turbine 01, a generator 02, and a lubrication system 04. The gas turbine 01 is a power component, which can provide power for the generator 02 to drive the generator 02 to operate and realize power generation; the generator 02 can convert kinetic energy into electrical energy to output electrical energy; the lubrication system 04 is used to provide lubricating oil for at least the gas turbine 01 and the generator 02, so that the gas turbine 01 and the generator 02 are fully lubricated, reduce wear, and ensure that the gas turbine 01 and the generator 02 can operate normally.

[0014] Among them, the lubrication system 04 may include a lubrication path 10, and components such as the gas turbine 01 and the generator 02 may be arranged on the lubrication path 10, so as to supply lubricating oil to at least the gas turbine 01 and the generator 02 through the lubrication path 10 to achieve lubrication of the gas turbine 01 and the generator 02.

[0015] Considering that components such as the gas turbine 01 and the generator 02 can generate heat respectively during operation, the lubricating oil will absorb part of the heat when passing through the gas turbine 01 and the generator 02, so as to achieve the cooling effect of the gas turbine 01 and the generator 02 through the lubricating oil. At the same time, the temperature of the lubricating oil that absorbs heat is increased.

[0016] In order to dissipate the heat of the lubricating oil, the lubricating system 04 may further include a first heat dissipation component 20, which includes a first radiator 21. The first radiator 21 is connected to the lubricating path 10, so that the lubricating oil transmitted by the lubricating path 10 can 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 with a lower temperature, so that the gas turbine 01, the generator 02 and other components can continue to be lubricated and cooled.

[0017] Considering that under some low temperature conditions, the gas outlet of the gas turbine generator set is prone to ice formation, the ice layer will cause the cross-sectional area of ​​the gas outlet to shrink, affecting the normal gas supply of the gas turbine generator set, thereby adversely affecting the normal operation of the gas turbine generator set.

[0018] Based on the above situation, the embodiment of the present application can set the first radiator 21 near the gas outlet of the gas turbine generator set, so as to dissipate heat to the area where the gas outlet is located through the first radiator 21, so that the temperature of the area increases, thereby effectively alleviating the problem of icing at the gas outlet. Based on the above configuration, the embodiment of the present application can supply lubricating oil to the gas turbine 01 and the generator 02 through the lubrication path 10 of the lubrication system 04, so that the gas turbine 01 and the generator 02 have a good lubrication effect, ensuring the stable operation of the gas turbine 01 and the generator 02; at the same time, the lubrication path 10 can also transport the lubricating oil that absorbs the heat of the gas turbine 01 and the generator 02 to the first heat dissipation component 20, and dissipate heat to the gas outlet of the gas turbine generator set through the first heat dissipation component 20, thereby increasing the temperature of the area near the gas outlet, and then having an anti-icing effect in a low temperature environment, so as to prevent ice from forming at the gas outlet and affecting the normal air intake of the gas turbine generator set.

[0019] refer to Figure 6In some embodiments, the gas supply port of the gas turbine generator set may include a gas turbine air inlet filter port 0612 and at least one air inlet filter port 0614. The gas turbine air inlet filter port 0612 is used to deliver gas to the surrounding environment of the gas turbine 01 to achieve ventilation of the surrounding environment of the gas turbine 01, which can cool down the gas turbine 01 to a certain extent; the air inlet filter port 0614 is used to deliver gas to the inside of the gas turbine 01 to ensure the gas required for the operation of the gas turbine 01. It should be noted here that the gas turbine air inlet filter port 0612 and at least one air inlet filter port 0614 can be arranged on the side wall of the fan accommodating cabin 061 of the auxiliary vehicle body described below.

[0020] In order to achieve the temperature increase effect at each gas delivery port, the first heat dissipation component 20 may include a plurality of first heat sinks 21, such as Figure 6 As shown, the plurality of first radiators 21 are respectively disposed at the engine air inlet filter port 0612 and at least one air inlet filter port 0614 , and the plurality of first radiators 21 are respectively connected to the lubrication path 10 .

[0021] Based on the above configuration, lubricating oil for absorbing heat from components such as the gas turbine 01 and the generator 02 can be respectively delivered to multiple first radiators 21 through the lubrication path 10, and heat can be transferred to the correspondingly arranged gas turbine air inlet filter 0612 and at least one air inlet filter 0614 through multiple first radiators 21, thereby effectively preventing ice from forming at the gas turbine air inlet filter 0612 and at least one air inlet filter 0614, thereby ensuring normal ventilation and normal air intake of the gas turbine 01.

[0022] Alternatively, if Figure 6 As shown, the air intake filter 0614 may include a driver's side air intake filter, a co-driver's side air intake filter and a rear side air intake filter. In addition, it may also include air intake filters 0614 located at other positions, so that a first radiator 21 can be provided to ensure that each air intake filter 0614 will not freeze, thereby ensuring smooth air intake and further ensuring sufficient air intake volume.

[0023] Continue to refer Figure 6 In some embodiments, the gas delivery port of the gas turbine generator set may further include a generator air inlet filter 0613, where 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 deliver gas to the surrounding environment of the generator 02 to achieve ventilation of the surrounding environment of the generator 02, which can cool down the generator 02 to a certain extent.

[0024] Based on the above configuration, lubricating oil that absorbs heat from components such as the gas turbine 01 and the generator 02 can be transported 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 from forming at the generator air inlet filter 0613 and ensuring normal ventilation of the generator 02.

[0025] Optionally, each of the air inlet filter ports 0614 , the gas turbine air inlet filter port 0612 , and the generator air inlet filter port 0613 may be provided with a port filter 091 to filter the input gas through the corresponding port filter 091 to ensure the cleanliness of the gas.

[0026] refer to Fig. 9 In some embodiments, the first radiator 21 may include heat sinks 211, which are distributed in a maze-like manner. Based on this arrangement, the surface area of ​​the heat sink 211 can be increased, thereby further improving the heat dissipation efficiency of the first radiator 21. At the same time, designing the heat sink 211 in a maze-like distribution can also block wind and sand in an environment with strong winds and sand, thereby preventing wind and sand from entering the first radiator 21 and affecting the heat dissipation efficiency of the first radiator 21.

[0027] In some more specific embodiments, an inertial filter may be provided on the outside of the first radiator 21, and the inertial filter may have an inertial filtering effect on the wind and sand, further alleviating the problem of the wind and sand entering the first radiator 21 and affecting its heat dissipation efficiency.

[0028] To achieve power transmission, Figure 3 and Figure 4 As shown, the gas turbine generator set may further include a gearbox 03, which is transmission-connected between the gas turbine 01 and the generator 02. Thus, during the operation of the gas turbine 01, the gearbox 03 may be driven to move, and the generator 02 may be driven to operate through the gearbox 03, so as to generate electricity through the operation of the generator 02.

[0029] Optionally, the gear box 03 may be a reduction box in the form of gears, etc.

[0030] Furthermore, the gear box 03 may also be connected to the lubrication path 10 so that lubricating oil can be supplied to the gear box 03 through the lubrication path 10 and the gear box 03 can be cooled.

[0031] refer to Figure 1In 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 circuit 13, and a second oil circuit 14. The oil inlets of the first oil circuit 13 and the second oil circuit 14 are respectively connected to the oil outlet of the oil tank 11, the oil outlet of the first oil circuit 13 is connected to the oil inlet of the oil tank 11, the oil outlet of the second oil circuit 14 is connected to the first oil circuit 13, the first oil pump 121 is provided in the first oil circuit 13, and the second oil pump 122 is provided in the second oil circuit 14. In addition, the gas turbine 01, the generator 02, and the gearbox 03 are respectively connected to the first oil circuit 13, and are all located in the downstream area of ​​the connection between the second oil circuit 14 and the first oil circuit 13.

[0032] 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 circuit 13 and flow from the oil inlet end to the oil outlet end of the first oil circuit 13; under the action of the second oil pump 122, the lubricating oil in the oil tank 11 can enter the second oil circuit 14 and flow into the first oil circuit 13 through the oil outlet end of the second oil circuit 14. Based on this, the lubricating oil can be supplied to the gas turbine 01, the generator 02 and the gear box 03 respectively through the first oil circuit 13, so as to achieve the lubrication effect on the gas turbine 01, the generator 02 and the gear box 03, and also can play a cooling effect on the gas turbine 01, the generator 02 and the gear box 03.

[0033] It should be noted that the first oil pump 121 can be a 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, the generator 02 and the gearbox 03 through the first oil circuit 13 under the action of the first oil pump 121 to achieve lubrication and cooling for the three respectively; when the first oil pump 121 fails, the second oil pump 122 can be started to transport lubricating oil to the first oil circuit 13 through the second oil circuit 14 under the action of the second oil pump 122, and supply lubricating oil to the gas turbine 01, the generator 02 and the gearbox 03 through the first oil circuit 13 to achieve lubrication and cooling for the three respectively.

[0034] Of course, in other embodiments, in order to increase the supply flow of the 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 converge in the first oil circuit 13 and flow to the gas turbine 01, the generator 02 and the gearbox 03 together to lubricate and cool the three respectively.

[0035] In order to further achieve the heat dissipation effect on the lubricating oil, the lubrication system 04 can also include a second heat dissipation component 30 arranged in parallel with the first heat dissipation component 20, so that the heat dissipation effect on the lubricating oil can be achieved through the second heat dissipation component 30 and the first heat dissipation component 20, thereby improving the heat dissipation efficiency.

[0036] The second heat dissipation assembly 30 may include a second heat sink 31, such as Figure 1 , Figures 5 to 8 As shown, the second radiator 31 is connected to the lubrication path 10, so that the lubricating oil that absorbs heat can be transported to the second radiator 31 through the lubrication path 10, and part of the heat in the lubricating oil can be dissipated outward through the second radiator 31, thereby achieving the heat dissipation effect of the lubricating oil, effectively preventing the lubricating oil from deteriorating due to excessive temperature and affecting the cooling effect on the gas turbine 01, the generator 02 and the gearbox 03.

[0037] Exemplarily, the second heat sink 31 may include heat dissipation fins to increase the heat dissipation area and improve the heat dissipation efficiency through the heat dissipation fins.

[0038] Continue to refer Figure 1 In some embodiments, the first oil circuit 13 may include a first main oil circuit 131, a second main oil circuit 132, a first branch oil circuit 133, and a second branch oil circuit 134. One end of the first main oil circuit 131 is connected to the oil outlet of the oil tank 11, and the first oil pump 121 is disposed in the first main oil circuit 131; one end of each of the first branch oil circuit 133 and the second branch oil circuit 134 is connected to the other end of the first main oil circuit 131, and the other end of each of the first branch oil circuit 133 and the second branch oil circuit 134 is connected to one end of the second main oil circuit 132, and the other end of the second main oil circuit 132 is connected to the oil inlet of the oil tank 11. Based on this arrangement, 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 circuit 131, and then flow from the first main oil circuit 131 into the first branch oil circuit 133 and the second branch oil circuit 134 respectively, and then be gathered from the first branch oil circuit 133 and the second branch oil circuit 134 to the second main oil circuit 132, and finally flow back to the oil tank 11 via the second main oil circuit 132, thereby realizing the circulation of the lubricating oil.

[0039] In addition, the oil outlet end of the second oil circuit 14 is connected to the second main oil circuit 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 circuit 14, and then flow from the second oil circuit 14 into the second main oil circuit 132, and finally flow back to the oil tank 11 through the second main oil circuit 132, thereby realizing the circulation of the lubricating oil.

[0040] The gas turbine 01, the generator 02 and the gear box 03 can be connected to the second main oil circuit 132 respectively, so as to supply lubricating oil to the gas turbine 01, the generator 02 and the gear box 03 respectively through the second main oil circuit 132, thereby achieving lubrication and cooling effects on the three; and after the lubricating oil passing through the gas turbine 01, the generator 02 and the gear box 03 absorbs a certain amount of heat, it flows back to the oil tank 11 through the second main oil circuit 132, so as to facilitate the subsequent reuse of the heated lubricating oil.

[0041] The first heat dissipation component 20 is connected to the first branch oil circuit 133 so that the lubricating oil after absorbing heat is supplied to the first heat dissipation component 20 through the first branch oil circuit 133, and the lubricating oil is dissipated by the first heat dissipation component 20 to reduce the temperature of the lubricating oil. At the same time, the first heat dissipation component 20 can dissipate heat to the gas outlet of the gas turbine generator set to prevent ice from forming at the gas outlet.

[0042] The second heat dissipation component 30 is connected to the second branch oil circuit 134 so that the lubricating oil after absorbing heat is supplied to the second heat dissipation component 30 through the second branch oil circuit 134, so that the lubricating oil is cooled by the second heat dissipation component 30 and the temperature of the lubricating oil is reduced.

[0043] Continue to refer 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 circuit 133 and the second branch oil circuit 134, the second oil inlet port 152 is connected to the first main oil circuit 131 through the first connecting oil circuit, and the oil outlet port 153 is connected to the second main oil circuit 132.

[0044] Based on the above configuration, 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, so that the lubricating oil can flow into the thermostat 15 through the second oil inlet port 152, and be directly discharged through the oil outlet port 153 of the thermostat 15. In 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 temperature of the lubricating oil from being too low and affecting the lubrication effect. It should be noted here that the above preset temperature is higher than the freezing temperature to prevent ice from forming at the gas delivery port at the preset temperature.

[0045] 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 is opened and the second oil inlet port 152 is closed, so that the lubricating oil enters the first branch oil circuit 133 and the second branch oil circuit 134 from the first main oil circuit 131, thereby dissipating and cooling the lubricating oil through 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 temperature of the lubricating oil from being too high and affecting the heat dissipation effect.

[0046] To further control the flow path of the 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 provided in the first branch oil path 133 and is located in the upstream area of ​​the first heat dissipation component 20; the second control valve 162 is provided in the second branch oil path 134 and is located in the upstream area of ​​the second heat dissipation component 30.

[0047] Based on the above settings, the first control valve 161 can be used to control the on / off state of the first branch oil circuit 133 or the flow rate of the lubricating oil, and the second control valve 162 can be used to control the on / off state of the second branch 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.

[0048] For example, when the temperature of the environment in which the gas turbine generator set is located is lower than the first low temperature value (e.g., minus 10 degrees Celsius), the gas outlet of the gas turbine generator set is prone to ice formation, and more heat is needed to prevent ice formation. Based on this situation, the opening of the first control valve 161 can be adjusted to the maximum position, and the second control valve 162 can be closed to allow a larger flow of lubricating oil to flow into the first heat dissipation component 20, so that the first heat dissipation component 20 can dissipate more heat to the gas outlet, thereby effectively preventing ice formation at the gas outlet.

[0049] When the temperature of the environment in which the gas turbine generator set is located is between the first low temperature value and the second low temperature value (wherein the second low temperature value is higher than the first low temperature value, such as the second low temperature value is 0 degrees, etc.), the gas outlet of the gas turbine generator set is generally easy to freeze. At this time, more heat is required to prevent freezing. 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 that a larger flow of lubricating oil flows into the first heat dissipation component 20, so that the first heat dissipation component 20 can dissipate more heat to the gas outlet, thereby effectively preventing the gas outlet from freezing. At the same time, part of the lubricating oil flows into the second heat dissipation component 30 to dissipate heat from the lubricating oil through the second heat dissipation component 30.

[0050] When the temperature of the environment in which the gas turbine generator set is located is higher than the second low temperature value, the gas outlet of the gas turbine generator set is not easy to freeze. At this time, less heat is required to prevent freezing. Based on this situation, the opening of the first control valve 161 can be adjusted to a smaller degree, and the opening of the second control valve 162 can be adjusted to a larger degree to ensure that a smaller flow of lubricating oil flows into the first heat dissipation component 20, so that the first heat dissipation component 20 can dissipate less heat to the gas outlet, thereby effectively preventing the gas outlet from freezing. At the same time, part of the lubricating oil also flows into the second heat dissipation component 30 to dissipate heat from the lubricating oil through the second heat dissipation component 30.

[0051] Based on the above situation, the embodiment of the present 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 in which the gas turbine generator set is located, thereby ensuring that the first heat dissipation component 20 can provide sufficient heat at the gas outlet of the gas turbine generator set to prevent freezing.

[0052] refer to Figure 2 and Figure 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 group 07.

[0056] The generator ventilation compartment air inlet 0521 and the third air outlet of the fan unit 07 can be connected through the third air pipe 083, so that 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 generator ventilation compartment air inlet 0521 in sequence, so as to ventilate the generator ventilation compartment 052 and realize the heat dissipation requirement of the generator 02 in the generator ventilation compartment 052.

[0057] It should be noted here that the first air outlet, the second air outlet and the third air outlet may be independent of each other, or may be the same air outlet.

In addition, arranging the first fan 071 and the second fan 072 in the up-down direction can fully utilize the space in the height direction of the auxiliary vehicle body 06 , which is beneficial to reducing the size of the auxiliary vehicle body 06 in the length direction.

[0061] Of course, the wind turbine group 07 may also include a third wind turbine, which is used to supply air to the gas turbine 01 .

[0062] refer to Figure 3 and Figure 4 The main vehicle body 05 may also be provided with a non-high-voltage cabin 053 and a high-voltage cabin 055 arranged along the length direction of the main vehicle body 05. A medium-voltage electrical cabinet and a low-voltage electrical cabinet may be arranged in the non-high-voltage cabin 053, and a high-voltage electrical cabinet may be arranged in the high-voltage cabin 055. Based on this arrangement, the high-voltage electrical cabinet can be separated from the low-voltage electrical cabinet and the medium-voltage electrical cabinet, thereby preventing maintenance personnel from being electrically injured during operation. For example, the non-high-voltage cabin 053 and the high-voltage cabin 055 may be arranged at intervals along the length direction of the main vehicle body 05.

[0063] refer to Fig.11 The auxiliary vehicle body 06 may also be provided with a transformer cabin 062, in which a transformer cabinet may be provided. The transformer cabinet is connected to at least one of the low-voltage electrical cabinet, the medium-voltage electrical cabinet and the high-voltage electrical cabinet through a cable to achieve transmission of electrical energy and signals.

[0064] In some embodiments, the gas turbine generator set may further include a gear box 03 drivingly connected between the gas turbine 01 and the generator 02, and the gear box 03 is disposed on the main vehicle body 05. Considering that at least part of the lubrication system 04 is disposed on the main vehicle body 05, the first heat dissipation assembly 20 may be disposed on the auxiliary vehicle body 06, and the lubrication path 10 extends to the auxiliary vehicle body 06 and is connected to the first heat dissipation assembly 20. Based on this, the lubricating oil may be transported to the first heat dissipation assembly 20 located in the auxiliary vehicle body 06 through the lubrication path 10, so as to dissipate heat to the gas delivery port of the gas turbine generator set through the first heat dissipation assembly 20, thereby playing an anti-icing role. Exemplarily, structures such as the oil tank 11, the first oil pump 121, and the second oil pump 122 may be disposed on the main vehicle body 05, such as Figure 3 shown.

[0065] Optionally, the first main oil circuit 131 may extend from the main vehicle body 05 to the auxiliary vehicle body 06 and be connected to the first heat dissipation assembly 20 through the first branch oil circuit 133 to deliver lubricating oil to the first heat dissipation assembly 20 .

[0066] In other embodiments, the second heat dissipation component 30 can be arranged on the auxiliary vehicle body 06. Accordingly, the lubrication path 10 can also be connected to the second heat dissipation component 30 after extending to the auxiliary vehicle body 06 to transport lubricating oil to the second heat dissipation component 30 and dissipate the lubricating oil through the second heat dissipation component 30.

[0067] In some embodiments, both ends of the portion of the first main oil circuit 131 located between the main vehicle body 05 and the auxiliary vehicle body 06 may be connected to the main vehicle body 05 and the auxiliary vehicle body 06 respectively through quick-connect connectors.

[0068] like Figures 5 to 8 As shown, the auxiliary vehicle body 06 may be provided with a gooseneck 063, and the second heat dissipation assembly 30 may be arranged at the gooseneck 063, so that the second heat dissipation assembly 30 is in an open-air environment, which can improve the heat dissipation efficiency of the second heat dissipation assembly 30 to a certain extent, and can also effectively save space and reduce the length of the auxiliary vehicle body 06. It should be noted here that the end of the auxiliary vehicle body 06 can extend into a step structure, which can be regarded as the gooseneck 063.

[0069] In addition, a duplex filter 092 may be provided on the gooseneck 063 . The duplex 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 .

[0070] Optionally, the first main oil circuit 131 may extend from the main vehicle body 05 to the auxiliary vehicle body 06 and be connected to the second heat dissipation assembly 30 through the second branch oil circuit 134 to deliver lubricating oil to the second heat dissipation assembly 30 .

[0071] refer to Fig.10In some embodiments, the main vehicle body 05 may include a load-bearing frame 054, which is at least composed of a non-carbon steel beam and a carbon steel beam. Based on this configuration, the load-bearing frame 054 can improve the load-bearing capacity of the main vehicle body 05, and it is also helpful to reduce the weight of the load-bearing frame 054 and reduce the risk of overweight. Compared with the welded carbon steel frame in the related art, it has the advantage of lightweight while ensuring the load-bearing capacity.

[0072] 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 pressure difference sensor 114, an electric heater 112, an oil tank temperature sensor 113, an oil mist remover 115, a check valve 163, etc. Fig.10 shown.

[0073] In addition, the lubrication path 10 may further include a pressure regulating valve 164, which is connected to the pressure regulating oil circuit, one end of which is connected to the oil tank 11, and the other end is connected to the first main oil circuit 131, and 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 be opened, so that the lubricating oil in at least one of the first main oil circuit 131 and the second main oil circuit 132 can flow back to the oil tank 11 through the pressure regulating oil circuit.

[0074] In the embodiment of the present application, the gas turbine generator set includes multiple operating modes, specifically: When the gas turbine generator set is started in cold state, the lubricating oil is heated by the electric heater in the oil tank 11 to reach the starting temperature required by the gas turbine; when the gas turbine generator set is started, the first oil pump 121 starts working in advance. At this time, the lubricating oil temperature does not reach the opening temperature of the thermostat 15, so that the lubricating oil does not pass through the first radiator 21 and the second radiator 31, but flows into the gas turbine 01, the generator 02 and the gear box 03 respectively after passing through the thermostat 15, and finally flows back to the oil tank 11. The specific path is as follows Fig.11 shown.

[0075] After the temperature of the lubricating oil reaches the opening temperature of the thermostat 15, and the anti-icing mode does not need to be turned on, 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 through the second branch oil path 134, so as to dissipate the heat of the lubricating oil through the second radiator 31; the lubricating oil after heat dissipation flows through the thermostat 15 and then flows into the gas turbine 01, the generator 02 and the gearbox 03 respectively, and finally flows back to the oil tank 11. The specific path is as follows Fig.12 shown.

[0076] When the ambient temperature is very low and the anti-icing mode needs to be turned on, 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 path 133 to dissipate heat to each gas outlet of the gas turbine generator set through the first radiator 21, thereby effectively preventing ice from forming at each gas outlet and causing blockage. The specific path is as follows Fig.13 shown.

[0077] Although the ambient temperature is very low, the gas turbine 01, generator 02 and gearbox 03 may generate a large amount of heat due to their high operating power, which may cause the temperature of the lubricating oil to be high, which is not conducive to the heat dissipation of the three. Based on this situation, the first control valve 161 and the second control valve 162 can also be opened at the same time. Under the action of the first oil pump 121, a part of the lubricating oil can flow into the first radiator 21 through the first branch oil circuit 133 and dissipate heat to each gas outlet of the gas turbine generator set through the first radiator 21 to play an anti-icing role; another part of the lubricating oil can also flow into the second radiator 31 through the second branch oil circuit 134 and dissipate heat to the lubricating oil through the second radiator. The specific path is as follows: Fig.14 shown.

[0078] Based on the above gas turbine generator set, the embodiment of the present application also discloses a heat dissipation control method, which is applied to the above gas turbine generator set. 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 .

[0079] The lubrication path 10 includes an oil tank 11, a first oil pump 121 and a first oil circuit 13. The first oil circuit 13 includes a first main oil circuit 131, a second main oil circuit 132, a first main oil circuit 131 and a second branch oil circuit 134. One end of the first main oil circuit 131 is connected to the oil outlet of the oil tank 11, and the first oil pump 121 is arranged in the first main oil circuit 131; one end of each of the first branch oil circuit 133 and the second branch oil circuit 134 is connected to the other end of the first main oil circuit 131, and the other end of each of the first branch oil circuit 133 and the second branch oil circuit 134 is connected to one end of the second main oil circuit 132, and the other end of the second main oil circuit 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 circuit 132.

[0080] Based on the above arrangement, 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 circuit 131 and flow into the first branch oil circuit 133 and the second branch oil circuit 134 respectively. The first branch oil circuit 133 and the second branch oil circuit 134 then collect the lubricating oil into the second main oil circuit 132, and transport it to the gas turbine 01 and the generator 02 respectively through the second main oil circuit 132, so as to realize the 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.

[0081] Furthermore, the first heat dissipation component 20 is connected to the first branch oil circuit 133, and the second heat dissipation component 30 is connected to the second branch oil circuit 134. Based on this configuration, the heat of the lubricating oil in the first branch oil circuit 133 can be dissipated through the first heat dissipation component 20, and the heat of the lubricating oil in the second branch oil circuit 134 can be dissipated through the second heat dissipation component 30.

[0082] Considering that the first heat dissipation component 20 is disposed at the gas outlet of the gas turbine generator set, the temperature at the gas outlet can be increased, thereby effectively alleviating the problem of icing at the gas outlet.

[0083] In order to control the flow of lubricating oil, the lubrication path 10 may also include a first control valve 161 and a second control valve 162, wherein the first control valve 161 is arranged in the first branch oil circuit 133, and the second control valve 162 is arranged in the second branch oil circuit 134. In this way, the flow of lubricating oil in the first branch oil circuit 133 can be controlled by the first control valve 161, and the flow of lubricating oil in the second branch oil circuit 134 can be controlled by the second control valve 162, thereby ensuring that the first heat dissipation component 20 can dissipate sufficient heat to the gas outlet of the gas turbine generator set and effectively prevent freezing.

[0084] Based on the above settings, the heat dissipation control method in the embodiment of the present application includes: When the anti-icing mode is started, the first control valve 161 is controlled to be open, and the second control valve 162 is controlled to reduce its opening or be closed, so that the flow rate of the lubricating oil in the first branch oil circuit 133 is increased, so that more lubricating oil flows into the first heat dissipation component 20, so that the first heat dissipation component 20 can dissipate more heat to the gas outlet of the gas turbine generator set, thereby playing an anti-icing role.

[0085] In some embodiments, the gas turbine generator set may further include a temperature detection element 0101 for detecting ambient temperature and a humidity detection element 0102 for detecting ambient humidity. For example, the temperature detection element 0101 may be a temperature sensor, and the humidity detection element 0102 may be a humidity sensor.

[0086] The heat dissipation control method includes: when the ambient temperature detected by the temperature detection element 0101 is lower than a preset temperature, and the ambient humidity detected by the humidity detection element 0102 is higher than a preset humidity, determining that the anti-icing mode needs to be started.

[0087] It should be noted here that real-time detection of ambient temperature and ambient humidity is used to determine whether the conditions for freezing are met, that is, when the ambient temperature is lower than the preset temperature and the ambient humidity is higher than the preset humidity, the freezing conditions are met. At this time, the gas turbine generator set can be started in anti-icing mode to prevent ice from forming at the gas outlet of the gas turbine generator set and affecting the air intake or ventilation volume.

[0088] In some embodiments, the gas turbine generator set may also include a pressure difference detection element 0103 for detecting a first pressure difference between the air inlet of the gas turbine 01 and the ambient pressure, a second pressure difference between the ventilation compartment of the gas turbine and the ambient pressure, and a third pressure difference between the ventilation compartment of the generator and the ambient pressure.

[0089] In an embodiment of the present application, the heat dissipation control method includes: when at least one of the first pressure difference, the second pressure difference and the third pressure difference exceeds the set pressure difference value, it is determined that ice blockage occurs at the gas outlet of the gas turbine generator set, and the first control valve 161 and the second control valve 162 are controlled accordingly to adjust the opening respectively until the first pressure difference, the second pressure difference and the third pressure difference do not exceed the set pressure difference value.

[0090] It should be noted here that when ice blockage occurs, it is necessary to increase the opening of the first control valve 161 and decrease or close the opening of the second control valve 162 to allow more lubricating oil to enter the first heat dissipation component 20, so that the first heat dissipation component 20 can dissipate more heat to the gas outlet of the gas turbine generator set to achieve the purpose of deicing.

[0091] In summary, the embodiment of the present application can dissipate heat for each gas transmission port of the gas turbine generator set through the first heat dissipation component 20 and the second heat dissipation component 30 to prevent the gas transmission port from freezing and affecting the normal operation of the gas turbine generator set; the heat sink 211 is designed in a maze form to prevent the entry of external wind and sand; The dual-carriage mode of the main car body 05 and the auxiliary car body 06 can effectively alleviate the problem of excessive vehicle load; the main car body 05 adopts a load-bearing frame 054 combining non-carbon steel and carbon steel, which can ensure the load-bearing strength and reduce the weight to avoid the risk of overweight; the gas turbine generator set as a whole shares a lubrication system 04, and adopts an oil supply method in which the first oil pump 121 and the second oil pump 122 cooperate to ensure that the gas turbine generator set continues to operate without shutting down due to a 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 cabin, and adopt an upper and lower layer arrangement. While meeting the ventilation needs of the gas turbine 01 and the generator 02, the length of the auxiliary car body 06 can be minimized.

[0092] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
