Description

Novel wind power transportation ship

Technical Field

The application belongs to the technical field of offshore wind power, and particularly relates to a novel wind power transportation ship.

Background

Under the 'double carbon' goal, china is greatly developing clean energy to reduce carbon emission. In the field of new energy power transmission, there are several power transmission modes at present, for long-distance land power transmission, an extra-high voltage direct current transmission technology is mostly adopted, and the most representative is a western electric east power transmission strategy, so that clean energy in northwest regions is converted into electric energy and is transported to eastern high-load power utilization regions. For offshore wind power, a submarine cable power transmission mode is adopted. In addition, a mode of converting wind power into hydrogen energy and then transporting the hydrogen energy exists. Although the above power transmission method has been developed and applied to some extent, there are still corresponding problems.

For example, the extra-high voltage transmission mode of constructing the transmission tower has the problems of stability and reliability of the system, and is only suitable for land areas. The power transmission mode of laying submarine cables and matching with a converter station is characterized in that the power transmission cost is approximately 500-1000 ten thousand yuan/kilometer, and the problems of high construction and maintenance cost are limited, so that the development of a deep sea wind power plant is limited; in addition, intermittent fluctuation power grid connection often has the problems of no power consumption requirement when the power is sufficient and insufficient power supply during the power consumption peak period, and is specifically expressed as follows: due to the fact that wind energy timeliness and environment dependence are limited, wind power generation has the characteristic of unstable output, the power transmission grid connection is challenged, the output peak of offshore wind power is often opposite to the actual urban power demand, the wind power is often smaller when the urban power load is large in daytime, the power supply is insufficient, the offshore wind power is increased when the urban power demand is reduced at night, the power supply is sufficient, and more power is wasted; in addition, the submarine power transmission cable has the defects of weak natural disaster resistance, influence on marine environment and the like.

The wind power hydrogen production is limited by the development of key technologies such as hydrogen energy storage and transportation, and the problems of poor safety, low efficiency and the like exist, and the wind power hydrogen production has no condition of large-scale application.

In order to solve the above technical problems, the prior art CN 217462403U discloses a multi-type distributed ocean power transmission system, which comprises an energy island with a set distance from a port, wherein an energy storage ship is arranged on the sea surface between the port and the energy island, the energy island transmits power to the energy storage ship through a direct current collector, and the energy storage ship operates to the port to discharge to complete power transmission.

The port is provided with an energy storage ship berthing area, and a direct current interface is arranged in the berthing area and used for being connected with the energy storage ship to receive electric energy. The direct current interface is connected with the electric ship berthed at the port to supply power for the electric ship, and the redundant power is inverted by the inverter and then is integrated into a power grid for running of port equipment.

However, in the existing multi-type distributed ocean power transmission system, a battery energy storage module on an energy storage ship is fixed on a ship body of the energy storage ship, cannot be detached, and can only supply power to a power utilization ship of a port through a direct current interface, but cannot transport stored power to land for land electric equipment (such as a large power supply base station for supplying power to commercial buildings and facilities, an electric vehicle charging station, an electric field energy storage project and the like), so that the use flexibility is poor, and the use requirement of people on the diversification of functions of the energy storage ship is difficult to meet. Meanwhile, once a certain battery energy storage module is damaged by a mechanical or circuit structure, mechanical or circuit connection between all the battery energy storage modules and the energy storage ship is adjusted, so that maintenance is inconvenient, effective connection between other normal battery energy storage modules and the energy storage ship can be influenced due to slight carelessness during maintenance, and the probability of occurrence of artificial accidents is greatly improved.

Step five, the staff boarding to install fixing pieces such as a bottom lock, a twist lock, a bridge lock and the like, is connected with a cable plug, checks whether the battery module is correctly fixed, and is connected to a control system of the ship.

Specifically, the container type battery module adopts a lithium iron phosphate battery, and has the advantages of high energy density, low self-discharge efficiency (< 0.3%/day), no obvious memory effect and the like. And along with the expansion of the application range of the lithium battery, the cost is gradually reduced, and the cost of 2025 is estimated to be reduced to 700 yuan/(kWh), so that the lithium battery becomes a high cost performance choice. According to the requirements of the use end and the size of the container type battery module, the container type battery module of the novel wind power transportation ship of the application is composed of battery units with two specifications, namely a small battery unit 2151 and a large battery unit 2152. Wherein the small battery unit can charge and supply power for automobiles or provide power for light trucks and small ships. The battery capacity of the small battery unit is 250 KWh, and the battery capacity of the current electric vehicle is 40-80 degrees, so that one small battery unit can meet the charging requirements of a plurality of electric vehicles, and at the practical application end, a plurality of small battery units can be configured into a group to charge the vehicles together with a charging gun. The large-sized battery unit can provide power for large-sized industrial vehicles, medium-sized electric and hybrid ships and the like or daily power supply, and can also provide power for a group of power supply base stations as an infrastructure or serve as a standby power supply. The battery capacity of the large battery unit reaches 800 KWh, and the size is relatively larger.

Wherein, the specification of the small-sized battery unit and the large-sized battery unit is shown in table 1 in detail.

The application scene of the container type battery module can be divided into four types, namely a power supply base station for supplying power to commercial buildings and facilities, an electric vehicle charging station, a battery for a ship or a charging station, and an electric field energy storage project. At the demand end, the battery units with large and small specifications can be distributed according to different purposes or packaged by using container type battery modules.

The first is a power base station for commercial buildings and facilities. This application requires a high level of electrical storage, which may take the form of one or more 40 foot container-type battery modules. The power supply base station can be used as a standby power supply of commercial buildings and facilities, can maintain the power supply of the buildings in the event of electricity utilization peaks or emergency, and can also supply power for small electric equipment of the buildings. The building operator can use the electricity exchanging service of the power supply base station in a leasing mode, can buy the container type battery module at one time, pay electricity exchanging cost once, or charge the power supply base station by self electricity using valley.

And the second is applied to a charging and power exchanging station of the electric vehicle. The electric vehicle power station and the power exchanging station can be built around the port. For small household electric vehicles, the charging mode is more suitable. Because of the numerous brands of various types of vehicles, the battery types are difficult to unify, the battery capacity is relatively small, and the charging can be completed in a short time. For this scenario, a 20 foot container battery module may be employed to power the vehicular charging piles. The container type battery module can provide electricity exchanging service for a charging station operator through a leasing mode or directly charge charging fees at a self-operating charging station. For large-scale engineering vehicles, such as heavy trucks, the power conversion mode is more suitable. For this application scenario, small-size or large-size battery units can be directly assembled and disassembled at the rear part of the vehicle head to supply energy according to the requirements and the size of the vehicle. When the electric quantity of the battery is used up, the battery unit can be directly assembled and disassembled in the battery replacing bin of the battery replacing station through the lifting device. The battery unit may be provided to the vehicle operator in a leased manner.

The third is applied to a marine battery or charging station, for example a battery or charging station applied on an electric watercraft. The pure electric driving mode is generally suitable for middle and small electric ships with short voyages. For this scenario, a medium-sized electric vessel may employ 20-gauge container-type battery modules mounted at the stern to power such vessels, which mainly employ a power-conversion approach to accomplish power replenishment, providing the battery to the vessel operator in a leased form. The specific method is as follows: the container type battery module is directly assembled and disassembled and lifted through a crane of the wharf, and the cable plug is plugged and pulled through manpower. For sightseeing small electric ships, small and large battery units can be used for power supply. The charging mode can be used for directly charging the ship through the charging gun, and the battery cell battery replacement service can also be used through the renting mode.

Fourth, energy storage items applied to electric fields. The wind power transport ship can be combined with an electric field, and the 40-ruler container type battery module is used as a part of an electric field energy storage project. Charging is performed when the electric field load is redundant or the electricity is low. And then, the idle time of the battery is utilized to participate in peak regulation and frequency modulation of the electric field in the peak period, so that the electric energy quality of the electric field is improved, and the operation cost is charged.

At the supply end, be different from traditional power supply mode, wind-powered electricity generation transport ship of this application carries out the transportation of electric power through loading, transportation container formula battery module.

As an improvement of the embodiment, the novel wind power transport ship of the present application preferably has a trimaran hull; the trimaran comprises a main hull 18 and two auxiliary hulls 19; the two auxiliary hulls are respectively and correspondingly arranged on the left side end and the right side end of the main hull; since the trimaran has stability superior to that of a conventional monohull ship, particularly roll stability, by providing two subsidiary hulls on the left and right ends of the main hull, it is possible to provide superior wave resistance, thereby better resisting the forces of natural disasters such as typhoons, earthquakes, and the like, and severe sea conditions (e.g., rough waves).

Meanwhile, as the waterline area of the trimaran is smaller, the hull is slender, and wave-making resistance can be effectively reduced when the trimaran runs at high speed, so that the navigational speed is improved, and the navigational range is increased. Compared with the traditional monohull ship, the triple hull ship design adopted by the novel wind power transportation ship can save about 20% of power. Meanwhile, the hull of the trimaran is slender, the interference influence on the propeller water flow is small, and the noise generated by the propeller can be effectively reduced, so that the influence on the ecological environment and marine organisms in the nearby sea area is relatively small. As a further improvement of the embodiment, the charging fixing area is arranged on the main hull, and the deck area of the main hull of the trimaran is wide, so that more effective loading area of the battery energy storage unit can be provided, and the carrying efficiency is improved.

The specifications of the trimaran used in the novel wind power transport vessel are shown in table 1 below.

Length of	100 meters
		Width of (L)	22.5 meters
Draft water	6.5 Rice
		Load-carrying capacity	3200. Metric ton
Course of voyage	1500. Kilometers
		Speed of speed	Standard: 10. section, maximum: 14. node
Battery capacity	50 megawatt hour

Considering the safety problem of lithium battery, because the electrode of lithium battery is easy to melt at high temperature to cause short circuit, the temperature control of the modularized battery is very important, and besides the temperature controller and the cooling fan are installed on the battery energy storage module, a reasonable centralized arrangement mode is needed to balance the heat dissipation and loading efficiency. A specific arrangement of the charging fixing area of the wind power transport ship is shown in fig. 11. According to the CSS class society specifications, the container-type battery module will be placed at the topside deck of the trimaran. The heat dissipation and ventilation are convenient, meanwhile, the large deck area of the trimaran is utilized to the maximum extent, and the battery loading capacity is increased.

Meanwhile, in order to further improve the loading capacity of the battery modules, as an improvement of the embodiment, the battery energy storage modules are multiple; the plurality of battery energy storage modules are arranged in a layered structure 4, as shown in fig. 13, wherein the layered structure is lower than the lowest end of the cab windshield of the ship body, so that the loading capacity is improved to the maximum extent while the vision is not blocked.

As a modification of the present embodiment, as shown in fig. 11, in the layered structure, each layer of the battery energy storage modules is arranged in a matrix in the longitudinal direction and the transverse direction; in addition, in the transverse direction, the distance between the adjacent battery energy storage modules is 0.35 meter, so as to better dissipate heat; on the longitudinal direction, the distance between adjacent battery energy storage modules is 1.5 meters, so that space is reserved for forklift and staff, and the battery energy storage modules can be conveniently assembled and disassembled and overhauled.

Since the capacity of the battery carried by the new wind power transport ship at a time is large (about 50 MWh), the charging speed at sea directly affects the overall power transport efficiency, and in particular, the hull is provided with a charging system (not shown); the first charging end is electrically connected with the charging fixed area through the charging system; the charging system comprises a megawatt charging system (such as a Cavotec MCS system), the highest charging power is up to 3MW, a single battery energy storage module (such as a 20-foot battery energy storage module, and the battery capacity is 1 MWh) is fully charged, the electric quantity can be charged to 80% only by 20 minutes, and the ultra-fast charging solution shortens the charging time of the battery energy storage module, so that the efficiency of power transportation is improved.

Meanwhile, in order to alleviate the polarization effect of the battery and thus increase the service life of the battery, the charging system further comprises a pulse charging system, and in the final stage of charging, the battery energy storage module can be trickle charged by using a pulse charging technology, and in a specific embodiment, as shown in fig. 12. By stopping charging at proper time, the charging current is changed to zero suddenly, ohmic polarization effect can be eliminated instantaneously, and concentration polarization and electrochemical polarization can be reduced effectively due to diffusion of electrolyte. Except for charging the novel wind power transportation ship in the deep open sea through the cable, the electric energy conveyed to the shore by the shallow offshore wind power station can be utilized when the ship approaches the shore, and the ship is charged in a wireless mode. Because the wireless charging needs to control the ship and the onshore charging coil to be kept in a reasonable offset range, the wireless charging system is very suitable for application on the onshore side with calm wind waves, and can help to consume shallow offshore wind power resources, and particularly, the charging system further comprises a wireless charging system 5; as shown in fig. 13, the wireless charging system includes a power receiving system provided on a hull side and a power transmitting system provided on a shore side; the power receiving system is used for supplying power to the first charging end and/or a ship body power system of the ship body; the power receiving system is connected with the power transmission system in a sensing way; the power receiving system comprises a power receiving cabinet 51 and a receiving coil 52; the power transmission system includes a power transmission cabinet 53 and a transmission coil 54; the transmitting coil is inductively connected with the receiving coil. The wireless charging system works on the principle that a divergent magnetic field is formed by a loose coupling transformer (not shown), and energy transmission is realized by space magnetic field coupling between a transmitting coil and a receiving coil.

Preferably, the transmitting coil is of a solenoid structure, and the receiving coil is of a double-decoupling winding structure, so that the coupling degree and the horizontal dislocation tolerance of the transmitting coil and the receiving coil can be effectively improved.

When the power of wireless charging is up to 1.2 MW, the heat dissipation problem of the coil needs to be considered. The wind power transport ship is characterized in that windings of the sending coil and the receiving coil are copper circulation tubes, so that liquid cooling can be used for central control in the winding, and meanwhile, the magnetic cores of the sending coil and the receiving coil are nanocrystalline magnetic cores in a matching mode, so that the charging and heat dissipation time ratio is controlled to be 1:1.

Preferably the back region of the receiving coil is provided with a magnetic field shield (not shown) to prevent exposure of the crew to a strong magnetic field. And, as shown in fig. 5, the wireless charging system is installed at the auxiliary hulls of the two sides of the wind power transport ship, and can charge the hull power system 6 and/or the battery energy storage module of the wind power transport ship when the battery energy storage module is assembled and disassembled and berthed.

With the increase of the number of novel wind power transportation ships and the perfection of related supporting facilities, a high-efficiency, green and zero-carbon emission power supply network can be formed, but the complexity of the system is increased, so that a powerful energy management system is required to monitor and manage the balance of a demand end at a supply end in real time, and the battery energy storage module is distributed more timely and more efficiently, and a charging route is planned. As shown in fig. 14, the cloud-based battery management system 7 may better solve this problem, where the battery management system includes a cloud 71, sensors 72 corresponding to the battery energy storage units one by one, and a control unit 73 corresponding to the sensors one by one; the corresponding sensor acquires state data (e.g., power data) of the corresponding battery energy storage module and uploads the state data to the cloud end through the corresponding control unit.

And uploading the real-time data of the battery energy storage units to the cloud through the sensors and the control units arranged on each battery energy storage unit, so that a battery network is formed. The data can be saved by a server with powerful terminal performance, and the battery supply networks can be optimized and managed by a more advanced algorithm.

Specifically, the hull power system comprises a main power supply, a standby power supply and a processing circuit; the main power supply and the backup power supply are respectively connected with the input end of the processing circuit, and the output end of the processing circuit is used for being connected with the ship integral control system. The main power supply comprises a power battery pack 61, the backup power supply comprises a hydrogen fuel cell 62, and the processing circuit comprises a chopper 63, a fuse 64, a direct current bus 65 and an inverter 66; the overall control system of the watercraft comprises a transformer 67 and an electric motor 68. The power battery pack is used as a main power supply, and the hydrogen fuel cell is used as a standby power supply, so that the voyage of the wind power transport ship is prolonged, and emergency is handled. As shown in fig. 15, the power battery pack and the hydrogen fuel cell are connected in series to the ship integral control system, so that electric power can be provided for the propulsion device and daily ship electric equipment can be maintained. When the hydrogen fuel cell is used as a power source, the wind power transport ship adopts a direct current networking mode, and is connected to a direct current bus after stabilizing the current amplitude through a chopper. The inverter on the dc bus can then convert the dc power to ac power for the wind power carrier propulsion devices (including the stern main propeller 181 and the bow auxiliary propeller 182) and the daily watercraft powered devices. And analyzing the overall electric energy and the electric energy demand of the hybrid power system through a battery management system, and preparing a system electric energy management implementation scheme. Specific electric propulsion modes include an economy mode, a full speed propulsion mode, a park mode, and the like. And when the load is not high, a part of power battery units are closed, and the hydrogen fuel battery charges the battery pack. The full-speed propulsion mode power battery pack and the hydrogen fuel cell are connected with each other simultaneously to supply power to the propulsion device, and the propulsion system runs at full power. The parking mode is powered by a single energy source, and the storage battery or the hydrogen fuel cell can be used for supplying daily loads. Compared with pure electric drive, the intervention of the hydrogen fuel cell increases the voyage of the transport ship and improves the flexibility and efficiency of electric power transportation. Besides the fuel supplementing on the shore, the hydrogen fuel cell can also supplement hydrogen fuel through an electrolytic water hydrogen production device of an offshore wind farm, so that wind power resources are further consumed. The hybrid power system of the electric power and hydrogen fuel cell uses completely green clean energy, reduces carbon emission, has low running noise, does not have the risk of fossil fuel leakage, and can effectively protect the local marine ecological environment.
