Description

Technical Field

[0002] With the rapid development of urban rail transit, straddle-type monorail trains have been widely used as an important means of transportation. Existing straddle-type monorail trains mainly rely on two power supply methods: third rail power supply and contact network power supply. This power supply method has the characteristics of high power and does not produce carbon emissions during the operation of the train, which is beneficial to environmental protection. However, this method requires the construction of complex ground power supply facilities, including laying the third rail or erecting the contact network, which not only increases the construction cost and prolongs the construction period, but also has certain safety risks, such as the possibility of electric shock accidents.

[0003] On the other hand, there are also some straddle-type monorail trains that use energy storage power supply systems, such as batteries or supercapacitors. These systems do not require the support of an external power grid and can solve the shortcomings of traditional power supply methods to a certain extent. However, the energy density of energy storage systems is relatively low, which means that in some cases, trains need to be charged frequently, especially on long-distance lines.

DETAILED DESCRIPTION

[0020] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0021] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied in the field of motor vehicle technology.

[0022] With the rapid development of urban rail transit, straddle-type monorail trains have been widely used as an important means of transportation. Existing straddle-type monorail trains mainly rely on two power supply methods: third rail power supply and contact network power supply. Studies have found that this power supply method has the characteristics of high power, does not produce carbon emissions during the operation of the train, and is beneficial to environmental protection. However, this method requires the construction of complex ground power supply facilities, including laying the third rail or erecting the contact network, which not only increases the construction cost and prolongs the construction period, but also has certain safety risks, such as the possibility of electric shock accidents.

[0023] On the other hand, there are also some straddle-type monorail trains that use energy storage power supply systems, such as batteries or supercapacitors. These systems do not require the support of an external power grid and can solve the shortcomings of traditional power supply methods to a certain extent. However, the energy density of energy storage systems is relatively low, which means that in some cases, trains need to be charged frequently, especially on long-distance lines. The energy storage system may not be able to provide enough energy to support the continuous operation of the train, thus affecting the train's operating efficiency and passengers' travel experience.

[0024] Based on this, an embodiment of the present application provides a hydrogen-electric hybrid power system, which improves the adaptability, stability and safety of the entire vehicle through a modular design of the hydrogen-electric hybrid power system, solves the technical problem in the prior art that there is only one energy storage device in the train and cannot provide sufficient energy to support the continuous operation of the train, and at the same time reduces the dependence on the ground power supply system.

[0025] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a hydrogen-electric hybrid system provided in an embodiment of the present application. Figure 1 As shown in , the hydrogen-electric hybrid power system provided in the embodiment of the present application is arranged on two adjacent target carriages in a straddle-type monorail train, and the hydrogen-electric hybrid power system 100 includes a controller 110, a hydrogen storage device 120, an energy storage device 130 and a hydrogen fuel cell power device 140, and the hydrogen storage device 120, the energy storage device 130 and the hydrogen fuel cell power device 140 are respectively connected to the controller 110.

[0026] Here, the hydrogen storage device 120 is mainly used to store the hydrogen required for the reaction of the hydrogen fuel cell power unit 140, and works in coordination with the hydrogen fuel cell power unit 140 to ensure that the hydrogen fuel cell power unit 140 has sufficient hydrogen supply, thereby maintaining the normal operation of the hydrogen-electric hybrid system 100.

[0027] The energy storage device 130 provides additional energy reserves for the straddle-type monorail train, so that it can be used when the hydrogen fuel cell power device 140 outputs insufficient power or when instantaneous high power is required. When the hydrogen fuel cell power device 140 or the hydrogen storage device 120 fails, the energy storage device 130 can continue to provide power support for the straddle-type monorail train to ensure the safe parking or transition operation of the straddle-type monorail train.

[0028] The hydrogen fuel cell power device 140 directly converts hydrogen and oxygen into electrical energy through chemical reactions, providing the main power source for the straddle-type monorail train. The hydrogen fuel cell power device 140 is the core component of the entire hydrogen-electric hybrid system 100, providing the main power output and providing a stable power supply for the train through an efficient energy conversion mechanism.

[0029] The controller 110 is connected to the hydrogen storage device 120, the energy storage device 130 and the hydrogen fuel cell power device 140. The controller 110 can monitor the operating status of each device in real time. When a device fails, it can generate corresponding control instructions according to a preset strategy to shut down the faulty device to ensure the normal operation of the entire hydrogen-electric hybrid system 100.

[0030] According to the embodiment provided by the present application, the hydrogen-electric hybrid power system 100 is installed on two adjacent target carriages in the straddle-type monorail train, and each hydrogen-electric hybrid power system 100 operates independently. When there are multiple hydrogen-electric hybrid power systems 100 in the straddle-type monorail train, each hydrogen-electric hybrid power system 100 does not affect each other. In this way, when a hydrogen-electric hybrid power system 100 in the straddle-type monorail train fails, it can be individually shut down to ensure the normal operation of other hydrogen-electric hybrid power systems 100. And through the modular design of the hydrogen-electric hybrid power system 100, the entire straddle-type monorail train has a high degree of power redundancy, which improves the adaptability, stability and safety of the whole vehicle. At the same time, the hydrogen fuel cell power device 140 in the hydrogen-electric hybrid power system 100 uses hydrogen as fuel, which is in line with the development trend of green transportation. The hydrogen-electric hybrid power system 100 is also provided with an energy storage device, which provides additional energy reserves, solving the technical problem that there is only one energy storage device in the train in the prior art and it cannot provide enough energy to support the continuous operation of the train. The hydrogen-electric hybrid system 100 reduces dependence on the ground power supply system and reduces construction and maintenance costs.

[0031] The hydrogen storage device 120 and the energy storage device 130 are respectively installed on different target carriages, and the hydrogen fuel cell power device 140 is installed at the bottom of any of the target carriages. The hydrogen fuel cell power device 140 is a special-shaped fuel cell suitable for the straddle-type monorail train.

[0032] See also Figure 2 , Figure 2 This is a hardware structure diagram of a hydrogen fuel cell power device provided in an embodiment of the present application. Figure 2 As shown, the present application takes into account the unique structure of the straddle-type monorail train and provides a special shaped fuel cell. The hydrogen fuel cell power unit 140 adopts a shaped fuel cell design. The hydrogen fuel cell power unit 140 includes a first radiator and a second radiator. The first radiator and the second radiator are respectively arranged on both sides of the monorail skirt. In this way, the hydrogen fuel cell power unit 140 can be arranged at the bottom of the straddle-type monorail train, and the space at the bottom of the vehicle can be fully utilized. This design not only improves the space utilization rate, but also ensures the stability and reliability of the hydrogen fuel cell power unit 140.

[0033] See alsoFigure 3 , Figure 3 is a schematic structural diagram of a hydrogen fuel cell power device provided by an embodiment of the present application. As Figure 3 shown, the hydrogen fuel cell power device 140 includes a thermal management unit 141, a fuel cell unit 142, a hydrogen processing unit 143, an air processing unit 144, and a fuel cell cooling unit 145. The fuel cell unit 142 and the fuel cell cooling unit 145 are respectively connected to the thermal management unit 141, and the hydrogen processing unit 143 and the air processing unit 144 are respectively connected to the fuel cell unit 142.

[0034] Here, the thermal management unit 141 is mainly used for temperature control and thermal balance. The fuel cell cooling unit 145 is mainly used to cool the thermal management unit 141. Continuing the above embodiment, the first radiator and the second radiator are located in the fuel cell cooling unit 145. The hydrogen processing unit 143 is mainly responsible for hydrogen supply and regulation, obtaining external hydrogen and sending it to the fuel cell unit 142. The air processing unit 144 is mainly responsible for oxygen supply, obtaining external air and sending it to the fuel cell unit 142. The fuel cell unit 142 is the core power generation unit, directly generating electric energy through the electrochemical reaction of hydrogen and oxygen.

[0035] Specifically, the thermal management unit 141 includes a water pump, a deionizer, a heater, etc. The heater is used to coordinate the temperature distribution inside the stack to prevent performance degradation caused by local overheating or low temperature. The fuel cell cooling unit 145 includes a radiator, a water tank, an electric fan, etc., which are used to adjust the temperature of the thermal management unit. The hydrogen processing unit 143 includes a hydrogen pump, pressure and flow regulation, safety pressure relief, and reflux, etc. Usually, the hydrogen processing unit 143 is connected to a hydrogen source to obtain the hydrogen generated by the hydrogen source. The hydrogen source usually includes a hydrogen cylinder and a pressure reducer. The air processing unit 144 includes an air filter, a silencer, an air compressor, an intercooler, a humidifier, etc. The air filter is used to intercept harmful impurities in the air, ensure the purity of the air entering the hydrogen fuel cell power device 140, enable the reaction to proceed efficiently, and at the same time extend the service life of the hydrogen fuel cell power device 140. Usually, the air processing unit 144 is connected to an air source to obtain the air generated by the air source. The air processing unit 144 is powered by high voltage and cooled using a BOP cooling system. The fuel cell unit 142 is usually also connected to an exhaust pipeline and a load.

[0036] Furthermore, the hydrogen fuel cell power device 140 also includes a control unit 146, and the thermal management unit 141, the fuel cell unit 142, the hydrogen processing unit 143, the air processing unit 144 and the fuel cell cooling unit 145 are respectively connected to the control unit. The control unit 146 monitors the key parameters of other units in the hydrogen fuel cell power device 140 in real time through sensors, and dynamically adjusts the operating parameters of each unit (such as hydrogen supply, air compressor speed, cooling pump power) according to the monitored data to maintain the optimal working state of the hydrogen fuel cell power device 140.

[0037] The hydrogen-electric hybrid power system provided in the embodiment of the present application is arranged on two target carriages adjacent to each other in a straddle-type monorail train, and the hydrogen-electric hybrid power system includes a controller, a hydrogen storage device, an energy storage device and a hydrogen fuel cell power device, and the hydrogen storage device, the energy storage device and the hydrogen fuel cell power device are respectively connected to the controller; the hydrogen storage device and the energy storage device are respectively installed on different target carriages, and the hydrogen fuel cell power device is installed at the bottom of any of the target carriages, and the hydrogen fuel cell power device is a special-shaped fuel cell suitable for the straddle-type monorail train.

[0038] This application uses a modular design of the hydrogen-electric hybrid power system to enable the entire straddle-type monorail train to have a high degree of power redundancy, thereby improving the adaptability, stability and safety of the entire vehicle. At the same time, the hydrogen fuel cell power unit in the hydrogen-electric hybrid power system uses hydrogen as fuel, which is in line with the development trend of green transportation. The energy storage device in the hydrogen-electric hybrid power system provides additional energy reserves, solving the technical problem in the prior art that there is only one energy storage device in the train and it cannot provide enough energy to support the continuous operation of the train. The hydrogen-electric hybrid power system reduces dependence on the ground power supply system and reduces construction and maintenance costs.

[0039] See also Figure 4 , Figure 4 This is a flow chart of a control method for a hydrogen-electric hybrid power system provided in an embodiment of the present application. The control method is applied to a controller in a hydrogen-electric hybrid power system, and the control method includes: S401, obtaining multiple operation status information.

[0040] Specifically, the multiple operating status information includes first operating status information of the energy storage device, second operating status information of the hydrogen storage device, and third operating status information of the hydrogen fuel cell power device.

[0041] With respect to the above step S401, in a specific implementation, the hydrogen-electric hybrid power system includes an energy storage device, a hydrogen storage device and a hydrogen fuel cell power device, and the controller obtains in real time the first operating status information of the energy storage device, the second operating status information of the hydrogen storage device and the third operating status information of the hydrogen fuel cell power device.

[0042] S402: When it is determined that abnormal state information exists in the plurality of operation state information, a target device to be controlled is determined based on the abnormal state information.

[0043] Among them, for the above step S402, in the specific implementation, after obtaining multiple operating status information, the controller determines whether there is abnormal status information in the multiple operating status information. If it is determined that there is no abnormal status information, the operating status of the energy storage device, the hydrogen storage device and the hydrogen fuel cell power device is continuously monitored. When it is determined that there is abnormal status information, the target device that needs to be controlled currently is determined based on the abnormal status information. Here, the target device is any one or more of the energy storage device, the hydrogen storage device and the hydrogen fuel cell power device.

[0044] S403: Generate a control instruction corresponding to the target device, and send the control instruction to the target device, so as to control the target device based on the control instruction.

[0045] Regarding the above step S403, in a specific implementation, after the controller determines the target device to be controlled, it generates a control instruction corresponding to the target device and sends the control instruction to the target device, so as to control the target device based on the control instruction.

[0046] In this way, according to the control method of the hydrogen-electric hybrid power system provided in the embodiment of the present application, the controller monitors the operating status of the energy storage device, the hydrogen storage device and the hydrogen fuel cell power device in real time. When there is a target device with an abnormal status, the target device is controlled in time to ensure the stable operation of the hydrogen-electric hybrid power system and the safety of the entire vehicle and the personnel on the train.

[0047] Specifically, according to the embodiment provided in the present application, when the abnormal status information is the first operating status information, the target device is the energy storage device, and the control instruction is a shutdown instruction of the energy storage device.

[0048] Here, the first control mode of the controller is that when the abnormal status information is judged to be the first operating status information of the energy storage device, it is considered that the operating status of the energy storage device is faulty, the energy storage device is determined as the target device to be controlled, and the generated control instruction is a shutdown instruction of the energy storage device to control the energy storage device to shut down.

[0049] When the abnormal state information is the second operating state information, the target device is the hydrogen storage device and the hydrogen fuel cell power device, and the control instruction is a valve closing instruction of the hydrogen storage device and a shutdown instruction of the hydrogen fuel cell power device.

[0050] Here, the second control mode of the controller is that when the abnormal status information is judged to be the second operating status information of the hydrogen storage device, it is considered that the operating status of the hydrogen storage device is faulty, and the hydrogen storage device and the hydrogen fuel cell power unit are simultaneously determined as the target devices to be controlled, and the generated control instructions are the valve closing instructions of the hydrogen storage device and the shutdown instructions of the hydrogen fuel cell power unit, so as to control the valve closing of the hydrogen storage device and the shutdown of the hydrogen fuel cell power unit.

[0051] When the abnormal state information is the third operating state information, the target device is the hydrogen fuel cell power device, and the control instruction is a shutdown instruction of the hydrogen fuel cell power device.

[0052] Here, the third control mode of the controller is that when the abnormal status information is judged to be the third operating status information of the hydrogen fuel cell power unit, it is considered that the operating status of the hydrogen fuel cell power unit is faulty, and the hydrogen fuel cell power unit is determined as the target device to be controlled, and the generated control instruction is a shutdown instruction of the hydrogen fuel cell power unit to shut down the hydrogen fuel cell power unit.

[0053] As an optional embodiment, the control method provided in the present application also includes: When the hydrogen fuel cell power device and the energy storage device are both in a shutdown state, a cut-off instruction is generated and sent to the traction motor of the carriage to control the traction motor to shut down.

[0054] With respect to the above steps, in the specific implementation, when the controller determines that the hydrogen fuel cell power unit and the energy storage unit are both in the shutdown state, a cut-off instruction is generated and sent to the traction motor of the carriage in which the traction motor is located to control the traction motor to shut down. In this way, in the actual operation of the train, when a hydrogen-electric hybrid power system fails, only the corresponding traction motor needs to be cut off to achieve the power-to-traction ratio of the train, thereby controlling the power output, energy efficiency and operating performance of the train, realizing flexible train formation and high power redundancy, and greatly improving the adaptability, stability and safety of the train.

[0055] See also Figure 5 , Figure 5 The following is a flow chart of a control method of a hydrogen-electric hybrid system provided in an embodiment of the present application. Figure 5As shown, at the beginning of the control method, the controller detects the operating status of the energy storage device, the hydrogen storage device and the hydrogen fuel cell power device. When the hydrogen storage device fails to operate, the valve of the hydrogen storage device is controlled to close; when the hydrogen fuel cell power device fails to operate, the hydrogen fuel cell power device is controlled to shut down; when the energy storage device fails to operate, the energy storage device is controlled to shut down. And when the hydrogen fuel cell power device and the energy storage device are in the shutdown state at the same time, the cut-off signal is triggered to control the traction motor to shut down.

[0056] As an optional embodiment, the control method further includes: The plurality of operation status information are sent to a train control and management system of the straddle-type monorail train.

[0057] With respect to the above steps, during specific implementation, after obtaining multiple operating status information, the controller can also send multiple operating status information to the train control and management system of the straddle-type monorail train. In this way, the train control and management system can monitor the status of the train according to the multiple operating status information sent by the controller, and conduct real-time monitoring and data analysis on the working status of each system during the train operation, so as to ensure the safe, stable and efficient operation of the train.

[0058] In the control method of the hydrogen-electric hybrid power system provided in the embodiment of the present application, the controller first obtains multiple operating status information; wherein the multiple operating status information include first operating status information of the energy storage device, second operating status information of the hydrogen storage device and third operating status information of the hydrogen fuel cell power device; then, when it is determined that abnormal status information exists in the multiple operating status information, the target device to be controlled is determined based on the abnormal status information; wherein the target device is any one or more of the energy storage device, the hydrogen storage device and the hydrogen fuel cell power device; finally, a control instruction corresponding to the target device is generated, and the control instruction is sent to the target device to control the target device based on the control instruction.

[0059] The present application uses a controller in the hydrogen-electric hybrid power system to monitor the operating status of other devices in the hydrogen-electric hybrid power system in real time, flexibly adjusts the working status of different power devices according to the actual operating conditions, and promptly controls the target device when there is an abnormal state, thereby ensuring the stable operation of the hydrogen-electric hybrid power system, thereby improving the overall safety of the train and enhancing the train's ability to respond to emergencies.

[0060] See also Figure 6 , Figure 6 This is a schematic diagram of the structure of a controller provided in an embodiment of the present application.
