Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of marine gas power generation, and in particular relates to a gas-steam combined cycle power generation barge. Background Technology
[0002] As a type of mobile floating power station, power-generating barges have gradually become an important solution for power shortages in areas far from the power grid, disaster emergencies, and emerging economies due to their convenient deployment and flexible power supply. However, existing technologies, which generally use traditional power-generating barges equipped with diesel generator sets, are incompatible with renewable energy equipment, limiting their application in environmentally sensitive areas. Furthermore, the prior art document (CN118220459A) shows that many launched barges adopt a "centralized stacking on deck" model, resulting in heavy equipment such as generator sets being concentrated in the upper part of the hull. This raises the overall center of gravity of the vessel, reducing stability, maintenance complexity, and costs. Compensating for the overall center of gravity usually involves increasing ballast and enlarging the hull size, increasing the overall construction cost. Additionally, the traditional fixed arrangement of "fixed installation inside the cabin" makes it difficult to achieve a compact layout of equipment. Insufficient integration often leads to low space utilization, resulting in low utilization of power generation materials and increased power generation costs.
[0003] Furthermore, existing power generation barges are ill-suited to the technical specifications required for power supply in various application scenarios. For example, in emergency power restoration after natural disasters (such as hurricanes destroying onshore power grids) or temporary power supply for large-scale events, power generation barges must be able to respond quickly to provide rapid power. In applications requiring continuous power supply, such as islands far from land-based power grids, offshore oil and gas platforms, or emerging industrial areas, power generation barges must operate stably and at low cost. Their adaptability is limited in specific marine environments. For instance, the deployment of current power generation barges is constrained by the redundancy of their structural design. In complex sea areas (such as high-wave zones and polar ice zones), the hull must meet both wind and wave resistance requirements and icebreaking requirements. The existing structural layout of power generation barges makes it difficult to flexibly adjust equipment counterweights and adapt to the inherent structural design of the hull. In addition, when upgrading existing power generation barges, the integration of power generation equipment cannot be further improved according to actual application needs. Furthermore, the fixed installation method of power generation equipment makes it difficult to dynamically optimize the arrangement of power generation equipment on the barge according to the requirements of the application scenario, resulting in poor adaptability to various application scenarios.

[0056] In the prior art, such as the prior art document (CN118220459A), a ship power system and launching barge are disclosed. This barge's power system is used for launching barges, which are equipped with a tower. Inside the tower is a distribution panel room, and above the distribution panel room is a corresponding top deck of the tower. The ship power system includes: a mobile generator set, detachably mounted on the top deck of the tower; a control docking box, mounted on the top deck of the tower and electrically connected to the mobile generator set; a power docking box, mounted on the top deck of the tower and electrically connected to the mobile generator set; and a main distribution board, located within the distribution panel room and electrically connected to both the control docking box and the power docking box. The prior art ship power system and launching barge, by installing a mobile generator set on the tower, only require the mobile generator set to be installed during operation, effectively simplifying the ship design of the launching barge and reducing its daily maintenance costs. For example, the combined cycle gas turbine generator unit of this invention has significant advantages in terms of maintenance cost and ease of operation compared to the hull arrangement when using a deck layout.
[0057] This utility model provides a gas-steam combined cycle power generation barge. It primarily addresses the problems of low integration, poor operational stability, and unreliable reliability in current power generation barges by integrating various equipment, such as the positions and heights of the gas-fired power generation unit and the gas supply unit, as well as their fixed positions and heights within the barge, and by optimizing the connection structure and relationships of the components of the gas-fired power generation unit. The power generation barge 100 of this utility model includes: a main body unit, on which a gas supply unit and a gas-fired power generation unit connected to the gas supply unit are located; the gas supply unit includes a fuel processing assembly located beside the gas-fired power generation unit; the fuel processing assembly and the gas-fired power generation unit are sequentially connected via pipelines; the fuel processing assembly and the gas-fired power generation unit are located on the deck structure of the main body unit or in a compartment below the deck structure; the gas-fired power generation unit is connected to an external power grid via a power transmission network; and a control unit located on the main body unit, which is electrically connected to the fuel processing assembly, the gas-fired power generation unit, and the power transmission network via control lines; wherein, in the power transmission branch output by the generator, the output end of the gas-fired power generation unit, the transformer, the control unit, and the power grid are sequentially connected. The gas-fired power generation unit includes a gas turbine power generation unit and a waste heat recovery power generation unit. The gas turbine power generation unit includes a gas turbine, a gas turbine generator rotatably connected to the gas turbine, and a waste heat boiler connected to the gas turbine, wherein the waste heat boiler is connected to the first waste heat generator. The waste heat recovery power generation unit includes a second waste heat boiler and a second waste heat generator, wherein the second waste heat boiler is connected to either the first or second waste heat generator, and the second waste heat boiler is connected to the first waste heat boiler. The control unit is electrically connected to the gas turbine, waste heat boiler one, and waste heat boiler two, respectively. The aforementioned gas supply unit (fuel processing assembly), gas-fired power generation unit, control unit, transformer power grid, etc., can all be installed on the hull unit of the barge 100 by mechanical bolts or welding. The outer shell of the hull unit adopts a hollow shell structure, with ballast water tanks designed at the bottom. By injecting or discharging water, the center of gravity of the barge 100 is adjusted to maintain its balance. The interior of the barge 100 is separated by watertight compartments (not shown in the figure), ensuring it will not sink in the event of partial damage to the watertight compartments.
[0058] In embodiments of this utility model, multiple gas turbines, waste heat boiler one, and first waste heat generator are provided; and / or at least one waste heat boiler two and second waste heat generator are provided.
[0059] In embodiments of this utility model, the fuel processing assembly may include multiple, such as m, fuel processing assemblies. These assemblies are arranged near the fuel-consuming equipment (such as a gas turbine) according to actual needs. This has the advantage of reducing pipelines between the fuel processing assembly and the gas turbine, avoiding the introduction of impurities during the process. Another advantage is that it allows different fuel-consuming devices (such as different models of gas turbines, different models of waste heat boiler one, and / or different models of waste heat boiler two) to achieve preset operating parameters when fuel parameters differ, through the setting of different delivery states in different fuel processing assemblies. Figure 1 The fuel handling assembly 1013A and fuel handling assembly 1013B shown are described. (The number of fuel handling assemblies 1013A and / or 1013B is m, where m ≥ 1, and m is set according to the number of gas turbines, waste heat boiler 1, and waste heat boiler 2, and design requirements.) When m is 1, the gas turbine, waste heat boiler 1, and waste heat boiler 2 can share a single fuel handling assembly based on actual conditions. The fuel handling assembly can be installed on the gas turbine deck of the barge hull. Figure 1 The diagram shows fuel handling components 1013A and 1013B symmetrically arranged on either side of a symmetrically arranged waste heat boiler 1, mounted on a deck structure. Fuel handling components 1013A and 1013B are connected to the fuel inlets of fuel-consuming equipment (such as gas turbines, waste heat boiler 1, and waste heat boiler 2) via pipelines. When the fuel-consuming equipment is a gas-fired power generation unit, the unit includes multiple gas turbines. The fuel handling components can perform one or more functions, such as temperature regulation, pressure regulation, overpressure protection, gas supply control, venting, and flow metering, depending on site requirements. Figure 1 In the structure shown, the waste heat power generation unit and the waste heat recovery power generation unit are perpendicular to the central axis of the gas turbine. This structural arrangement is based on... Figure 1 As shown, the gas turbine power generation unit, which is most suitable for placement on the deck, is arranged on the deck structure, achieving high space utilization and the best width-to-height ratio.
[0060] In embodiments of this utility model, such as Figures 1 to 7As shown, the power generation barge 100 may include multiple gas-fired power generation units, such as gas-fired power generation units 101, 102, 103, 104, and 105. This number is only an example; it can be configured up to a Q-th gas-fired power generation unit (Q is set according to the size of the power generation barge 100 and the size of the gas-fired power generation units). Correspondingly, the waste heat boiler can be configured as a supplementary combustion type waste heat boiler. This waste heat boiler can also include multiple units, and its gas inlet is connected to the fuel processing components via pipelines. For example, the waste heat boiler can include a first waste heat boiler 1006, a second waste heat boiler 1008, a third waste heat boiler 1007, a fourth waste heat boiler 1009, and a fifth waste heat boiler 1010. Each gas-fired power generation unit includes a gas turbine generator set and a corresponding waste heat boiler connected to it. For example, the first gas turbine generator set 1001 is connected to the corresponding first waste heat boiler 1006, the second gas turbine generator set 1002 is connected to the corresponding second waste heat boiler 1008, the third gas turbine generator set 1003 is connected to the corresponding third waste heat boiler 1007, the fourth gas turbine generator set 1004 is connected to the corresponding fourth waste heat boiler 1009, and the fifth gas turbine generator set 1005 is connected to the corresponding fifth waste heat boiler 1010. The inlet of the fuel processing component is connected to the upstream gas supply equipment (the connection between the fuel processing component and the upstream gas supply equipment is not shown in this invention; the upstream gas supply equipment can be installed on the hull, such as an LNG system, or it can be installed outside the barge hull) via pipeline. Through the above arrangement, this invention achieves a high degree of integration of a power generation system that matches and combines different types of gas turbine power generation units and waste heat recovery power generation units, ensuring high energy density within the necessary maintenance space.
[0061] In one embodiment of this utility model, the waste heat power generation unit and / or waste heat recovery power generation unit is an expansion generator unit. For example... Figure 1As shown, when the waste heat generator set 1 operates as a non-waste heat recovery secondary expansion generator set, it generates electricity. When the waste heat generator set 1 operates as a waste heat recovery unit, if it uses a liquid medium such as water to produce steam, the waste heat generator set 1 is a steam turbine generator set (the same applies below). The waste heat recovery power generation unit includes a first waste heat recovery generator set 1011 and a second waste heat recovery generator set 1012. The first waste heat recovery generator set 1011 can be an expansion generator set (when operating as a waste heat recovery unit, if it uses a liquid medium such as water to produce steam, the first waste heat recovery generator set 1011 is a steam turbine generator set, the same applies below). The second waste heat recovery generator set 1012 can be an expansion generator set (when operating as a waste heat recovery unit, if it uses a liquid medium such as water to produce steam, the second waste heat recovery generator set 1012 is a steam turbine generator set, the same applies below). It should be noted that the number of the above-mentioned waste heat generator sets 2 can be S. When S is 1, the waste heat generator set 2 is the first waste heat recovery generator set 1011. Optionally, there can be multiple second waste heat recovery generator sets 1012, which can be arranged in various ways. For example, both the gas turbine power generation unit and the waste heat recovery power generation unit can be arranged on the deck structure. In this scheme, all power generation equipment is installed on the deck structure. Their arrangement can be staggered between the waste heat recovery power generation unit and the waste heat generator set 1 of the gas turbine power generation unit, or the power generation equipment of the waste heat generator set 1 and the waste heat recovery power generation unit can be arranged together, with various permutations and combinations. The advantage of this arrangement is that it allows for centralized maintenance and inspection. In the case where the waste heat generator set 1, the waste heat recovery power generation unit, the gas turbine generator, and the first waste heat generator are not arranged on the deck, they can be distributed on a fixed structural layer in the spatial direction of the hull. The waste heat generator set 1 and the waste heat recovery power generation unit can be connected by pipes, and the electrical control part is electrically connected to the control unit 1019. Barge 100 optimizes space utilization in its height arrangement and achieves an optimized height-to-width ratio by combining single-layer or multi-layer layouts. This reduction in height or width lowers the hull's size and tonnage, decreases steel consumption, and thus reduces costs. Waste heat generator units and waste heat recovery power generation units are mechanically connected to the hull. The advantages include saving width dimensions, fully utilizing height space, increasing the duty cycle of the main hull units, and achieving high energy density.
[0062] In one embodiment of this utility model, the transformer includes a main transformer, used to transform the voltage of the electrical energy generated by the first waste heat generator and the second waste heat generator, so that the voltage of the output power meets the requirements of different users or the power grid supplying external power. The main transformer may include multiple transformers, such as... Figure 1As shown, the main transformers include a first main transformer 1017, a second main transformer 1018, a third main transformer 1025, and a fourth main transformer 1026. The capacity and voltage level specifications of these main transformers are not entirely the same. For example, the first main transformer 1017 can be configured as a medium-voltage transformer, the second main transformer 1018 as a low-voltage transformer, and the third main transformer 1025 and the fourth main transformer 1026 as high-voltage transformers, according to the user's actual needs. The main transformers 1017 to 1026 can be configured according to different capacity and voltage level specifications, and the types of these main transformers are not limited to oil-immersed transformers and dry-type transformers, which will not be elaborated further here.
[0063] In this embodiment of the invention, an oil-immersed transformer is used as an example. The main transformer mainly consists of an iron core, windings, an oil tank and cooling device, protection device, and bushings. The iron core is the core component of the main transformer. Generally, its structure is made of hot-rolled or cold-rolled silicon steel sheets coated with insulating varnish. The core structure includes the magnetic circuit that forms the main transformer, guiding magnetic flux to form a closed loop, reducing magnetic resistance, and improving magnetic flux efficiency. The windings are located in the circuit section of the main transformer and are made of insulated copper or aluminum wire. They are divided into high-voltage windings and low-voltage windings. The high-voltage winding is connected to the input high-voltage side and bears the high voltage; the low-voltage winding is connected to the output low-voltage side and supplies power to the load. These windings are used to transfer electrical energy through electromagnetic induction, enabling voltage transformation and power transmission in the main transformer. The windings also have leads and insulation structures. The leads connect the windings to the external circuit, while the insulation ensures electrical insulation between components, preventing leakage and short circuits. Insulating paper and insulating materials are typically used.
[0064] In embodiments of this utility model, the oil tank in the oil tank and cooling device is generally used to hold transformer oil, providing a sealed space to dissipate heat, provide insulation, and protect the windings. It also needs to meet the mechanical strength requirements of the transformer during operation, maintenance, and transportation. The cooling device is generally air-cooled, but liquid-cooled structures can also be installed via pipelines. Common cooling devices include, but are not limited to, radiators, fans, and submersible pumps. Radiators increase the heat dissipation area, transferring the heat generated during transformer operation to the cooling medium (air is a common cooling medium in air cooling); fans accelerate airflow, improving heat dissipation; submersible pumps force oil circulation, allowing the transformer oil to circulate between the oil tank and radiator, carrying away heat. The above-mentioned different types of cooling devices are adapted to different types and specifications of main transformers, and are not specifically limited here.
[0065] In embodiments of this utility model, the protection device comprises instruments, related valves and pipelines, and corresponding control elements to measure, detect, and protect the operating parameters of the main transformer. Taking common protection devices as examples, it includes, but is not limited to, an oil level gauge, a pressure relief valve, a gas relay, and a dehumidifier. The oil level gauge is used to observe the insulating oil level; the oil thermometer measures the insulating oil temperature in real time; the pressure relief valve is a component that opens to release pressure when abnormal pressure occurs; the gas relay is installed on the connecting pipeline between the oil tank and the oil conservator; and the dehumidifier is filled with silica gel to achieve breathing and moisture absorption functions. The oil level gauge reflects the oil level through the principle of communicating vessels or mechanical and electronic sensing methods; the oil temperature gauge converts temperature into an observable signal based on the principles of thermal expansion and contraction and thermocouples; the pressure relief valve utilizes the balance between internal pressure and spring pressure, opening the valve when the internal pressure exceeds a set value; the gas relay operates based on the amount of gas generated by a fault and the oil flow rate; the dehumidifier uses the physical adsorption properties of silica gel to absorb moisture from the air, ensuring the insulating oil is at the appropriate level and maintaining the insulation and heat dissipation performance of the main transformer; the oil temperature gauge displays and monitors the heating status of the main transformer, taking timely measures to prevent overheating damage at high temperatures; the pressure relief valve releases pressure when the internal pressure is too high, preventing the oil tank from exploding; the gas relay can sensitively detect internal faults, issuing a warning signal for minor faults and quickly tripping to cut off the power supply in case of serious faults; the dehumidifier prevents moisture from entering, avoiding transformer oil aging due to moisture and extending the service life of the main transformer. In addition, the outgoing bushing consists of a conductive rod and an insulating sleeve, used to lead out the winding terminals and ensure insulation between the windings and the oil tank. Depending on the voltage level and current capacity, various types of bushings can be selected, including but not limited to porcelain bushings and silicone rubber bushings.
[0066] In one embodiment of this utility model, the control unit includes a first control system, a second control system, a third control system, a fourth control device, and a switching device. The first control system is electrically connected to the second control system, the third control system, the fourth control device, and the switching device. The first control system is also electrically connected to the gas turbine electrical and fuel processing components, and is used to control the adaptive operation of the gas turbine electrical and fuel processing components. The second control system is electrically connected to the first waste heat boiler and the second waste heat boiler, and is used to control the first waste heat boiler and the second waste heat boiler to match actual needs and control their adaptive operation as required. The third control system is an excitation control system 1021C, which is electrically connected to the gas turbine generator, the first waste heat generator, and the second waste heat generator. The excitation control system 1021C includes an excitation regulator, an excitation power unit, and an auxiliary control section. The excitation regulator is used to adjust the excitation current of the generator in real time according to the power conditions of the generator operation. Through precise adjustment, the excitation regulator ensures that different types and specifications of generators (gas turbine generators, first waste heat generators, and second waste heat generators) maintain stable voltage and frequency output under various operating conditions, thereby guaranteeing the stability of the generator's power output. The excitation power unit, composed of a rectifier, excitation transformer, and corresponding control circuits, provides the required DC current to the generator's excitation winding, ensuring that the generator outputs the required excitation current stably and reliably under the control of the excitation regulator. In addition, the auxiliary control section includes sensors such as voltage, current, and temperature sensors to collect and monitor the voltage, current, and temperature operating status of the generators controlled by the excitation control system 1021C, and to take timely protective measures in case of abnormalities, further improving the safety and reliability of the generators under the control of the excitation control system 1021C.
[0067] In one embodiment of this utility model, the fourth control device is a control room device, including a control console. In the power transmission branch output by the generator, the gas turbine generator, the first waste heat generator, and the second waste heat generator are sequentially connected to the transformer, the switchgear, and the power grid, respectively. The switchgear is a gas-insulated switch. The aforementioned gas-insulated switch can be a sulfur hexafluoride enclosed switchgear (GIS). The GIS switch highly integrates the control and output of the generators (excluding the transformer) in the substation, as well as the output after transformer transformation, within a pre-defined, confined space. This highly integrates the gas-fired power generation units and their optimized connections, improving the power supply density of the power generation barge. In this utility model, the first and second waste heat generators are stepped up by a transformer and then connected to the GIS switch, supplying power to the power grid or other power-consuming sides via two outgoing lines. The outgoing lines of the GIS switch can be connected to the gantry structure via cables at intervals. Its power grid can also be networked through the gantry structure, further optimizing the spatial arrangement of the barge hull.
[0068] In one embodiment of this utility model, the control unit further includes a control tower, which is disposed above the bottom of the cabin and fixedly connected to the deck structure. The control tower has at least one control layer structure, and the first control system, the second control system, the excitation control system 1021C, the control room equipment, and the switching equipment are respectively disposed in the control tower. For example, the control tower of the control unit 1019 can be divided into X1 to X2 layers or 1 to X layers (b≥X1≥-a, b≥X2≥-a, and X2≥X1, X∈[X1,X2], a≥1, b≥1). If a=b=1 and X1=X2=1, then only the 0th layer of the deck structure is the deck layer, the lower layer below the deck layer is the cabin, and the layer above the deck layer is the first floor 1019-1 of the control tower. The first control system 1019A, the second control system 1019B, and the GIS switch can be located on the first floor (1019-1) of the control tower. The excitation control system 1021C and the control room equipment system 1021D can also be located on the first floor (1019-1) of the control tower if the control tower has only one floor. If the control tower has multiple floors, the excitation control system 1021C and the control room equipment system 1021D can be located on other floors besides the first floor of the control tower, such as... Figure 3As shown, the excitation control system 1021C and the control room equipment system 1021D are located on the second floor 1019-2 of the control tower. The control tower can be configured as a multi-story building, either above or below the deck structure. When the control tower is configured as a multi-story building, it is connected to the deck structure. Depending on the number of floors on the side of the control tower, a portion of the lower floors can be located in the cabins below the deck structure, and a portion of the upper floors can be located above the deck structure. The control tower can be a multi-story control tower whether it is located above the aforementioned cabins and / or deck structure, which will not be elaborated further here.
[0069] In one embodiment of this utility model, the first control system 1019A or the second control system 1019B can adopt a first connection structure. The first connection structure mainly adopts a hierarchical modular design, including a sensing and execution module, a control core module, and an auxiliary integration module. The sensing and execution module sets various parameter sensors and connects each sensor to the bus of the actuator of each system in the control unit through network cables for real-time acquisition, monitoring, and interaction of execution commands. The control core module is used for redundant controller integration protection system and sequential logic, and coordinates with each gas turbine, steam turbine, and auxiliary part to eliminate redundancy via industrial Ethernet. The auxiliary integration module is used to control the fuel handling component to switch fuels, and can also control the environmental protection subsystem (linked and interacted via hardwired / CAN bus). The above control layers can achieve efficient and reliable control through redundant communication (such as hot standby synchronization, edge-cloud collaboration), meeting the target optimization and intelligent operation and maintenance needs of the multi-control module barge 100 power generation operation.
[0070] In one embodiment of this utility model, the first connection structure may further include an intelligent optimization module or a human-machine interaction module. The intelligent optimization module employs a digital twin and AI diagnostic module to further dynamically optimize the operating parameters during multi-barge power generation, meeting the stability requirements of real-time adaptive intelligent operation and maintenance. The human-machine interaction module supports multi-protocol communication through a human-machine interface (HMI) and a remote monitoring platform, enabling remote human-machine monitoring to meet the requirements of unmanned on-site operation. The control unit 1019 of the aforementioned first connection structure can achieve intelligent control of the gas turbine combined cycle unit through the hierarchical architecture of the control tower. At the sensing and execution layer, a sensor network (such as temperature, pressure, and vibration probes) distributed across the gas turbine, expansion generator set, waste heat boiler, and auxiliary equipment collects operating parameters in real time and transmits them to the control core layer via a fieldbus. The control core layer employs redundant or non-redundant controllers (TMRs) that execute core logic such as combustion control, load distribution, and overspeed protection based on computation and voting mechanisms. Through communication coordination, it coordinates the actions of the gas turbine and steam turbine, ensuring dynamic response speed and anti-interference capability. The intelligent optimization layer can employ various methods, such as: simulating thermal stress changes using digital twin models, combining AI algorithms to analyze historical data and predict equipment health status, dynamically optimizing start-up and shutdown strategies and maintenance cycles; the human-machine interface layer integrates multi-protocol communication through a visual interface (HMI) and remote monitoring platform to achieve parameter monitoring and remote diagnostics; auxiliary modules (such as multi-fuel switching and exhaust gas treatment) are electrically connected to the aforementioned bus to ensure environmental compliance and fuel flexibility. Each layer forms a closed-loop control system through redundant or non-redundant communication (hot standby synchronization, edge-cloud collaboration), ensuring the real-time performance and reliability of critical signals while reducing unplanned downtime risks through predictive maintenance, ultimately achieving efficient and stable unit operation. Furthermore, space can be reserved for the hierarchical architecture of the control tower for future dismantling and protection.
[0071] In one embodiment of this utility model, the first control system 1019A or the second control system 1019B may also adopt a second connection structure, which includes a PLC main control unit and a second intelligent optimization module. The PLC main control unit mainly consists of a PLC controller and a memory, and also includes a modularly integrated number of I / O modules, a communication network module, and a power supply module. The PLC main control unit is used for combustion regulation of various gas turbines, speed control of various rotating equipment, load distribution and liquid level control of various types of units, speed, vibration, fuel pressure, and temperature monitoring of various temperature measuring points. It also presets alarm and shutdown safety modules as needed, and uses a non-redundant or redundant architecture as needed to complete the transmission and synchronization of the above data in the I / O modules through communication modules and cables. Specifically, the analog module of the I / O module collects the pressure / temperature signals, speed signals, and drives the regulating valves of the above components; the digital module of the I / O module processes the switch inputs / outputs; and the safety module of the I / O module independently manages emergency stop, overspeed protection, and over-limit shutdown according to the actual operating conditions. The aforementioned I / O modules can also connect to local or remote I / O stations for data transmission and synchronization via cables and bus modules using specific communication protocols. For example, data visualization can be achieved through a communication network-based host computer (HMI / SCADA), while critical signals (such as ESD) maintain stable communication via hard-wired connections. The second intelligent optimization module includes an expansion module, which can preprocess vibration spectra for the computing unit and incorporate digital twin and AI diagnostic modules, improving the operational efficiency of the power generation barge through cloud-based collaboration. All these modules seamlessly collaborate through layered communication and redundancy mechanisms, balancing high-precision control, flexible expansion, and safety compliance, supporting the stable operation and intelligent upgrades of the power generation barge's generator sets. The second connection structure is centered around a PLC, integrating signal processing, logic control, and communication functions through modular design. The PLC main control unit receives analog signals (such as temperature and pressure) and digital signals (such as valve status and emergency stop commands) from the gas turbine and expander generator set (such as a steam turbine). It executes a preset PID control algorithm to adjust the fuel valve opening, speed, and load distribution. Simultaneously, it handles overspeed and vibration exceeding limits protection signals through corresponding modules or components to prevent system malfunction due to a single fault. The I / O modules are connected locally and remotely via an industrial bus (such as Profinet). Preferably, distributed control is used to reduce wiring complexity and improve scalability. The host computer (SCADA / HMI) interacts with the PLC to visualize and trace operational data. An intelligent optimization layer, as an optional extension, preprocesses vibration spectrum data through an edge computing unit (reserving space for later refined protection) and optimizes control parameters using a cloud-based digital twin model to assist in operation and maintenance decisions (reserving space for later refined protection).Alternatively, the system employs a hot standby architecture and a ring redundant network to ensure seamless switching in case of controller failure. Key protection circuits retain hard-wiring design, balancing control flexibility and safety fault tolerance, thereby maintaining stable output and long-term operation of the generator set under all operating conditions. This invention, through the aforementioned modular structural designs and division into different functional modules, enables the design and combination of different functional modules for the hull of the barge 100 with varying requirements. This simplifies the functional layout of the control structure, saves cables and space, and simultaneously meets the various required functional configurations.
[0072] In one embodiment of this utility model, the barge 100 may include one or more layers of cabins. For example... Figure 2 As shown, when the barge 100 has only one compartment, a hydraulic system 1024 is installed in the compartment. The hydraulic system 1024 includes a water treatment system 1023 and a cooling system 1022. The water treatment system 1023 and the cooling system 1022 are connected to the first waste heat boiler and the second waste heat boiler respectively via pipelines, and are connected to the first control system respectively via wires. When the barge 100 has multiple compartments, the water treatment system 1023 and the cooling system 1022 can also be located in different compartments (not shown in the figure), which will not be described in detail here.
[0073] In one embodiment of this utility model, the hydraulic system 1024 realizes the water intake, water supply, and drainage of the unit. Generally, the hydraulic system 1024 includes a cooling subsystem 1022, a water pump and water storage subsystem, a fire-fighting water subsystem, a water collection and reuse subsystem, and a seawater desalination subsystem (note: some connections may be combinations of these subsystems or mergers). The outlet pipeline of the hydraulic system 1024 and the inlet pipeline of the water treatment system 1023 are mechanically connected via connectors (connection methods include, but are not limited to, flange connections, joint connections, threaded connections, adhesive connections, welding, etc., hereinafter the same), which will not be elaborated further. In the electrical structure, if some mechanical connections require electrical components in one system to be connected to electrical components or control cabinets in another system, this can be achieved using cables and cable connectors (the aforementioned connectors include, but are not limited to, cable connectors, terminals, and connections where the internal metal parts of the cable are soldered or wrapped with tubing or insulating tape for insulation at the connection point), similar situations will not be elaborated further below.
[0074] In one embodiment of this utility model, the water treatment system 1023 is used to purify, desalinate, deoxygenate, and chemically regulate water to ensure that the water quality meets the unit's operating requirements and to prevent scaling, corrosion, or salt buildup in the equipment. Generally, the water treatment system 1023 includes a raw water pretreatment subsystem, a desalination subsystem, a deoxygenation subsystem, a chemical dosing subsystem, and a water quality monitoring subsystem, etc. (the number of subsystems can be reduced and is not shown in the figure).
[0075] In one embodiment of this utility model, the gas turbine power generation unit is arranged in at least one of horizontal and vertical structures. For example, the first gas turbine generator set 1001, the second gas turbine generator set 1002, the third gas turbine generator set 1003, the fourth gas turbine generator set 1004, the fifth gas turbine generator set 1005...the Qth gas turbine generator set can be arranged in either horizontal or vertical configuration. Similarly, the corresponding waste heat boiler 1, including the first waste heat boiler 1006, the second waste heat boiler 1008, the third waste heat boiler 1007, the fourth waste heat boiler 1009, the fifth waste heat boiler 1010...the Qth waste heat boiler, can also be arranged in either horizontal or vertical configuration. Alternatively, the gas turbine generator sets and the corresponding waste heat boilers in the above-mentioned multiple gas turbine power generation units can be respectively arranged in horizontal-horizontal, horizontal-vertical, vertical-horizontal, vertical-vertical, etc. configuration structures. Figure 4 As shown, the vertical gas turbine generator set 1025-1 in the first structural state and the horizontal waste heat boiler 1026-1 in the first structural state are vertically arranged and connected by the first mechanical connection component 1027-1. The horizontal waste heat boiler 1026-1 in the first structural state is located in the height space next to the vertical gas turbine generator set 1025-1 in the first structural state. The aforementioned first mechanical connection component 1027-1 can be mechanically connected by a threaded connection structure. The structural forms of the above-mentioned multiple gas turbine power generation units can be combined with each other through the threaded connection structure. By utilizing the gas turbines with cold and hot exhaust at both ends in the process of matching combined cycle power generation, different hull width-to-height ratios of structural optimization and configuration can be achieved, reducing space occupation and increasing the space density of the gas turbine power generation units.
[0076] In one embodiment of this utility model, such as Figure 5As shown, the vertical second-structure gas turbine generator set 1025-2 and the vertical second-structure waste heat boiler 1026-2 are arranged parallel to each other and connected by a first mechanical connection component 1027-1. The first mechanical connection component 1027-1 can be an L-shaped connecting pipeline with a threaded connection at the interface. The top of the vertical second-structure waste heat boiler 1026-2 can be higher than the vertical second-structure gas turbine generator set 1025-2, and its bottom is located in the height space beside the vertical second-structure gas turbine generator set 1025-2 and is mechanically connected by the L-shaped first mechanical connection component 1027-1. Figure 6 As shown, the vertical third-structure gas turbine generator set 1025-3 and the vertical third-structure waste heat boiler 1026-3 are arranged parallel to each other and connected by a first mechanical connection component 1027-1. The top of the vertical third-structure waste heat boiler 1026-3 is located within the height space beside the vertical third-structure gas turbine generator set 1025-3, and the bottom is located below the bottom of the vertical third-structure gas turbine generator set 1025-3. The top of the vertical third-structure waste heat boiler 1026-3 and the side of the vertical third-structure gas turbine generator set 1025-3 are mechanically connected by an L-shaped first mechanical connection component 1027-1. Figure 7 As shown, the vertical fourth-structure gas turbine generator set 1025-4 is located below the vertical fourth-structure waste heat boiler 1026-4 and is mechanically connected via a long, straight first mechanical connection component 1027-1. As an optional embodiment, the first mechanical connection component 1027-1 can be replaced by a second mechanical connection component 1027-2, wherein the second mechanical connection component 1027-2 is a long, straight, or L-shaped mechanical connector with a flange at the connection end. The structural forms of the aforementioned multiple gas turbine power generation units can be optimized and combined through flange connection structures to reduce space occupation and increase the spatial density of the gas turbine power generation units, which will not be elaborated further here.
[0077] In one embodiment of this utility model, the second waste heat boiler is configured in at least one of horizontal and vertical configurations. For example, the waste heat boiler 2 can be configured in horizontal, vertical, or other structural forms (not shown in the figure). For instance, the waste heat boiler 2 connected to the gas turbine generator set may include at least four boilers. Specifically, one boiler may be connected to the first waste heat boiler in a horizontal-horizontal configuration, another to the first waste heat boiler in a horizontal-vertical configuration, another to the first waste heat boiler in a vertical-horizontal configuration, and another to the first waste heat boiler in a vertical-vertical configuration. The structural configurations of these multiple gas-fired power generation units connected to the waste heat boiler 2 can be freely combined to optimize and reduce space occupation and further increase the space density of the gas-fired power generation units; further details are omitted here.
[0078] In one embodiment of this utility model, the barge 100 includes both powered and unpowered barges. The powered barge may integrate its fuel supply with other equipment, such as sharing a fuel supply unit with the gas supply unit of a power-generating barge. The power system of a powered barge generally includes a power unit, a transmission unit, and a propeller. Preferably, the power unit is generally located at the rear of the barge hull (near the propeller), thus shortening the length of the drive shaft. The transmission unit is generally arranged along the center or offset of the barge's bottom. The propeller is generally located in the middle to rear of the barge hull, and can be positioned at the stern. A propeller and rudder are installed at the stern (engine drives forward, rudder adjusts direction), combined with navigation and radar for real-time obstacle avoidance. Deep-sea barges can also be equipped with wave-damping side plates to reduce wave impact. Dynamic positioning of the propeller (automatically fine-tuning position to resist ocean currents) and anti-corrosion coatings (rust prevention and extended lifespan) ensure a coordinated overall structure of the power unit, enabling collaborative operation and balancing buoyancy, stability, and precise control. This enables the power-generating barge 100 to operate in specific marine environments. For powered barges, the power and fuel systems can be integrated with other equipment. Taking a diesel-fueled barge as an example, the power system is based on a diesel engine and consists of a main engine, shaft system, fixed-pitch propeller, fuel supply system (including fuel tank, treatment components, and injection system), turbocharger, exhaust gas treatment (if required), lubrication and cooling components, etc. Diesel fuel is compressed and ignited in the cylinder, driving the piston to reciprocate. This is converted into rotational power via the crankshaft, which drives the propeller to generate thrust through the reduction gearbox and long shaft. The exhaust gas turbocharger increases the intake air density to enhance combustion efficiency. Corresponding exhaust gas treatment components are installed according to emission requirements. The power systems of both powered and unpowered barges are controlled by the control unit 1019, or separately connected and controlled by the propulsion control system of the barge power system, which will not be elaborated further here.
[0079] In one embodiment of this utility model, the connection between the gas turbine generator, the first waste heat generator, and the second waste heat generator and the transformer includes at least one of the following: phase-separated enclosed busbar connection, common-enclosure enclosed busbar connection, and insulated copper pipe busbar connection. For example, when the generator set of the gas turbine power generation unit is connected to the GIS switch after being stepped up by a step-up transformer, and the power is supplied to the power grid or other power consumption side using a two-way outgoing line method, the generator set and the transformer can be connected by one of the following: phase-separated enclosed busbar, common-enclosure enclosed busbar, and insulated copper pipe busbar. A cable connection is used between the high-voltage side and the GIS switch. The GIS switch adopts an indoor single-sided structure layout, which can significantly reduce the width of the building. The step-up substation adopts a single-story structure layout, with a network control building located on one side of the substation. The network control building houses protection, control, and remote communication equipment related to the GIS switch and the main transformer, which will not be described in detail here.
[0080] In one embodiment of this utility model, the power generation barge 100 further includes a gantry structure mounted on the deck structure. The gantry structure is positioned above the step-up transformer and connected to the foundation beneath it. The step-up transformer can be installed outdoors, with a fireproof isolation wall structure between the transformers. This fireproof isolation wall structure can significantly reduce the distance between the transformers and improve the space utilization of the barge 100's main body unit. Furthermore, the transformer can be located near the step-up substation. Figure 1 As shown, the first main transformer 1017, the second main transformer 1018, the third main transformer 1025, and the fourth main transformer 1026 are respectively installed on the foundation structure under the gantry structure (not shown in the figure) near the control unit 1019. If the gas-fired power generation unit is installed on the deck, taking a 100MW-class power generation barge as an example, the deck structure allows personnel direct access for equipment maintenance (e.g.,...). Figure 1 (The shaded area represents the maintenance area). A rough estimate suggests that labor costs can be reduced by 15%-25%, downtime shortened by 20%-40%, and in gas turbine and steam turbine maintenance, the gantry structure can directly lift spare parts for gas turbine generator units, transformers, and other equipment during large-scale hoisting operations, increasing replacement and maintenance efficiency by 50%. Furthermore, the deck structure offers excellent ventilation, whereas the hull layout, due to its confined space, requires additional ventilation equipment and frequent structural disassembly, increasing labor and spare parts costs by 30% and 50% respectively, resulting in an average annual maintenance cost approximately 50% higher than the deck layout. Regarding maintenance difficulty, the deck structure offers ample equipment inspection space (≥2m), allowing for standardized operations with low safety risks (see...). Figure 1 The maintenance area is in the shaded part. The internal working space of a ship is generally narrow (≤0.5m), which requires special tools and the risk of harmful gas accumulation in the confined space is increased by 2-3 times. Personnel also need to be additionally trained in marine regulations (costs increase by at least 30%).
