Electrical ship equipment with energy generation, distribution and consumer systems, in particular for surface vessels

The invention relates to electrical ship furnishing with energy generation, distribution and consumer systems, in particular for surface vessels, with at least one generator designed in the HTSL design, at least one motor designed in the HTSL design and a cryosupply device, by means of which the at least one HTSL generator and the at least one HTSL motor can be supplied with a cryotechnical cooling agent.

Submarine and surface vessels usually have complex electrical ship equipment, which leads to a high proportion by weight and volume of electrical energy generation, distribution and consumer systems. In addition, the most diverse components of the electrical

Ship equipment for cruise ships, merchant ships, fishing vessels, container ships, frigates and submarines and the like. can be cooled in a complex manner, for which purpose, for example, intermediate cooling circuits that are recooled with sea water, ventilation ducts, by means of which, for example, machine rooms can be dewarmed, additional fans, etc., are used. In addition, other components of electrical ship equipment, for example transformers, electrical machines and lubrication devices and the like, for the operation of which the use of 01 is often required, result in high fire loads, which require complex safety measures.

The object of the invention is to develop an electrical ship's equipment of the type described above in such a way that it reduces the installation volume and the installation weight can be produced with less economic effort.

This task is solved in accordance with the fact that further components and operating resources of the energy generation, distribution and consumer systems are designed in HTSL design and can be supplied with cryotechnical coolant by means of the cryosupply device. The design of further components and equipment in the HTSL design in connection with their cooling by means of the cryosupply means that the components and equipment can be produced with a significant reduction in both the installation volume and the installation weight with less economic effort, with known electrical ship equipment on the one hand Existing fire loads do not arise at all in the case of the electrical ship equipment according to the invention and, on the other hand, the ship volume required for cooling and heat dissipation measures can be considerably reduced.

The configuration of the electrical ship equipment according to the invention ensures that either the charge capacity of an otherwise unchanged surface ship is significantly increased or, on the other hand, a surface ship with the same charge capacity can be made considerably smaller. The lack of space on board submarines can be alleviated. Your range when underwater can be increased.

If the HTSL generators of the electrical marine equipment according to the invention, which are designed as synchronous machines with superconducting magnet wheel and air gap windings, have superconducting bearings that can be supplied with cryotechnical coolant by means of the cryosupply device, there is an improvement in efficiency from approx. 95% to approx . 98.5%, whereby the energy expenditure for the operation of the cryosupply is taken into account, and a reduction in the machine masses and the machine volume to about 50%.

Comparable volume, mass and efficiency advantages with regard to the motor equipment of the electrical ship equipment according to the invention can be achieved if instead of conventional motors HTSL motors with superconducting bearings are provided which are supplied with cryotechnical coolant by means of the cryosupply device.

According to an advantageous further development of the electrical marine equipment according to the invention, at least one rotary forming motor generator is designed as a synchronous machine of the HTSL type, the superconducting magnet wheel and air gap windings being able to be supplied with cryotechnical coolant by means of the cryosupply device. This increases the efficiency in comparison to a conventional rotary forming motor generator from 95% to approx. 98.5%, taking into account the energy expenditure required for cooling; the machine mass and the machine volume are reduced in comparison to a conventional embodiment to approximately 50%, the above percentages being achievable, in particular, with relatively little effort if the HTSL rotary forming motor generator has superconducting bearings which are provided by means of the cryosupply device can be supplied with cryotechnical coolant.

With comparable achievable advantages, superconducting bearings can expediently be provided for further rotating components of the electrical ship equipment, for example for turbines, these superconducting bearings also being supplied with cryotechnical coolant by means of the cryosupply device. The superconducting bearings reduce friction losses, improve efficiency by up to 0.7%, reduce maintenance and eliminate lubricating oil circuits and coolers. which represent high fire loads; only emergency storage facilities are necessary in the event of a failure of the cryotechnical coolant supply.

If the electrical marine equipment according to the invention has a HTSL design and has transformers with superconducting transformer windings which can be supplied with cryotechnical coolant by means of the cryosupply device, the efficiency of the transformers can be increased from approx. 98% to approx. 99%, the energy expenditure for the

Cooling is taken into account, increase, whereby furthermore achieved ei ^¬ ne reduction in the electric machinery volume and mass of the electrical machine by approximately 30 to 40% who can ^¬. This applies to both converter and distribution transformers.

If the DC link chokes provided in the DC link converters are HTSL-type and can be supplied with cryotechnical coolant by means of the cryosupply device, the efficiency in comparison with a conventional DC link choke can be increased from approx. 98% to approx. 99%, taking into account the energy expenditure for cooling. increase; the reduction in volume and mass is approximately 40 to 50%.

A cryogenic cooling of converters by means of the cryosupply device can achieve a considerable reduction in the on-state resistances, which, for example in the case of MOSFETs, can be a maximum of approx. 87% with a cooling of 77 K compared to the room temperature of approx. 300 K.

If busbars or cables that electrically connect cryogenically cooled components to one another are designed in a HTSL design and can be supplied with cryotechnical coolant by means of the cryosupply device, losses can otherwise occur due to the temperature difference between the Cryogenic temperature and room temperature can be significantly reduced.

Advantageously, DC link chokes provided in DC link rectifiers can be connected together with line-side and machine-side power converter modules and housed in a common cryostat in such a way that power supplies and the losses caused thereby can be reduced to a minimum.

Comparable savings can thus be achieved if voltage intermediate circuit capacitors provided in voltage intermediate circuit converters are designed in cryogenic or HTSL design and can be supplied with cryogenic coolant by means of the cryosupply device together with network-side power converter modules and machine-side power converter modules. This makes it possible to accommodate them in a cryostat, which means that several power supply lines as main loss carriers in the cryostat can be dispensed with.

HTSL busbars or HTSL power cables are particularly advantageous for the electrical connection of cryogenically cooled load centers and cryogenically cooled consumer centers.

If current limiters designed as HTSL-type safety elements are provided in the electrical ship equipment according to the invention and can be supplied with cryotechnical coolant by means of the cryosupply device, the operation of the on-board electrical system can be improved by the fact that now the possibility of coupling previously separate system parts and reducing the dynamic ones and thermal effects of short-circuit currents is possible, which leads overall to an improvement in the security of supply and an improvement in the effects of line perturbations caused by converter loads which is achieved by increasing the short-circuit power. Magnetic energy stores of the electrical ship equipment according to the invention can advantageously also be designed in a HTSL design and can be supplied with cryotechnical coolant by means of the cryosupply device.

The cryosupply device of the electrical ship equipment according to the invention is expediently at least partially redundant in order to increase the safety of ship operation.

If the cryosupply device of the electrical marine equipment according to the invention is designed as a central cooling system, advantages in terms of the economic outlay for cryocooling can be achieved; Furthermore, cryosupply devices known from the prior art, which are used industrially, can be adapted to the requirements of shipbuilding without great economic and technical outlay. The design as a central cooling system also enables a higher Carnot efficiency compared to individual systems with smaller capacities.

The design of the cryosupply device as a decentralized cooling system is advantageously accompanied by shorter transfer lines, with the decentralized design also ensuring that not all HTSL components depend on a single cryogenic system.

Depending on the design of the electrical ship equipment according to the invention, it is advantageous if its cryosupply device has centrally designed and decentrally designed partial cooling systems, a centrally designed partial cooling system advantageously being associated with a load center with a large number of coolant consumers, in which only short transfer lines are provided. Decentralized partial cooling systems are suitable for isolated and remote coolant consumers.

In addition, a decentralized partial cooling system is required if coolant consumers are provided which are cooled with a coolant other than that provided in the rest of the cryogenic supply device. For surface marine vessels, where damage due to a hit must not lead to failure of the entire propulsion system, it is particularly advantageous if a decentralized partial cooling system of the cryosupply device is assigned to a drive train with at least one converter transformer, at least one converter and a motor.

If the cryosupply works with liquid nitrogen as the coolant, which has a boiling temperature of 77 K which is usually sufficient for cryogenic cooling, advantages can be achieved in so far as liquid nitrogen is non-combustible and as liquid nitrogen from air, the main component of which is nitrogen gas, without can be obtained, the corresponding process technologies are environmentally friendly and nitrogen is not toxic.

As additional coolants, e.g. Liquid natural gas, liquid oxygen, helium, neon, argon and / or air can be provided as secondary coolant and / or as coolant of decentralized partial cooling systems of the cryotechnical supply device. Liquid natural gas, for example, is in

Natural gas tankers are available, and liquid hydrogen, which can also be used as a coolant, is available, for example, in fuel tanks for operating fuel cells; For example, helium is used as a coolant at particularly low temperatures and as a working gas for the supply of cold heads to refrigerators. The cryogenic supply device can also be used to supply shock-freezing devices, refrigerated containers and the like, which are present, for example, on board fish-processing ships, with cryotechnical coolant.

The cryosupply device can advantageously have an air liquefaction system for generating liquid nitrogen. There is practically unlimited air available to operate the air liquefaction system.

The liquid nitrogen can advantageously be buffered in a collection container so that the cryosupply device can be operated in a base load, whereas the coolant consumers on board the overseas ship can be supplied with cryotechnical coolant as required. In the event of a failure of the electrical system, the coolant consumers can be kept cold from the collection container for a certain time.

Refrigerators have proven to be particularly advantageous as decentralized partial cooling systems, the refrigerators expediently each forming a closed system.

Compressors assigned to the refrigerators can expediently be recooled by means of water, for which purpose either individual recooling circuits are set up or several refrigerators can have an intermediate circuit cooling system common to them.

Depending on the local location of the refrigerators, cooling via the side wall by means of sea water is possible, for example.

If at least one fuel cell is assigned to the electrical ship equipment according to the invention, this can be partially operated with liquid oxygen accumulating in large quantities in the air liquefaction inventory.

Process refrigeration for food cooling is required on board cooling vessels and fishing vessels. A cryosupply device described above can be designed taking into account all conceivable consumers, wherein different cooling temperature levels can be achieved for different purposes; For this purpose, the use of heat exchangers with different or the same refrigerants is possible.

It should be noted that the liquid natural gas already mentioned above as a coolant is present in large quantities in the tanks of liquid gas tankers. The liquid natural gas has a boiling temperature of 111 K at a pressure of 1 atm and can therefore be used as a refrigerant for certain cooling purposes. In addition, the tanks have natural evaporation rates. The resulting gaseous natural gas, possibly also appropriately evaporated natural gas, can be used to drive the turbine of the electrical marine equipment according to the invention. The liquid natural gas can be used as a cryogenic refrigerant in those HTSL components for which the cooling temperature of 111 K is sufficient, for example in heat shields or, if appropriate, directly at superconductor transition temperatures which are above 111 K.

The electrical ship equipment according to the invention is advantageously equipped with high-speed semiconductor switches, which are supplied with cryotechnical coolant by means of the cryosupply device, so that their continuously occurring transmission losses can be considerably reduced.

In the following the invention is explained in more detail by means of embodiments with reference to the drawing. Show it :

Between the two network sections 4, 5, a current limiter 6 is arranged, which is supplied by the cryosupply device 3 with the cryogenic coolant. Using the HTSL current limiter 6, it is possible to couple previously separate system parts, which considerably improves the operation of the ship's network; Dynamic and thermal effects of short-circuit currents are reduced by the HTSL current limiter 6. By coupling previously separate systems, the security of supply can be improved, and by increasing the short-circuit power, the effects of network perturbations caused by converter loads can be improved.

The lower network section 4 in the illustration in FIGURE 1 branches into three network branches. A rotary forming motor generator 7 is provided in a network branch, by means of which, for example, an illumination device of the surface ship can be operated. The rotary forming motor generator 7 is designed in a HTSL design as a synchronous machine with superconducting magnet wheel and air gap windings and is supplied with cryotechnical coolant by means of the cryosupply device 3.

In a further network branch of the lower network section 4 in FIG. 1, a drive train with a converter transformer 8, a converter 9 and a motor 10 is provided, by means of which a ship propeller 11 can be driven.

The converter transformer 8 is designed in a HTSL design with superconducting windings and is supplied with cryotechnical coolant by the cryosupply device 3. The components of the converter 9 are also cooled by means of the cryosupply device 3 or the cryotechnical coolant provided thereby.

The motor 10 is also manufactured in a HTSL design and is supplied with cryotechnical coolant by the cryosupply device 3. The bearings of the HTSL motor 10 are designed as superconducting bearings corresponding to those of the HTSL generator 2 or the turbine 1.

At the top in the illustration of FIGURE 1 power branch of the power unte ^¬ ren portion 4 of the ship network is a converter transformer 12 and a voltage source 13 is provided, are supplied via the different electrical loads.

The converter transformer 12 is designed in a HTSL design with superconducting windings and is supplied with cryotechnical coolant by the cryosupply device 3.

The voltage intermediate circuit converter has a network-side power converter module 14, a voltage intermediate circuit capacitor 15 and a machine-side power converter module 16. The voltage intermediate circuit capacitor 15 is designed in a HTSL design and is supplied with cryotechnical coolant by the cryosupply device 3 together with the network-side power converter module 14 and the machine-side power converter module 16.

A further converter transformer 17, a current intermediate circuit converter 18 and a further motor 19 are arranged in a network branch of the upper network section 5 of the ship's network in FIG. 1, by means of which a second ship propeller 20 can be driven. The further converter transformer 17 is designed in a HTSL design with superconducting windings and is supplied with cryotechnical coolant by means of the cooling supply device 3.

The DC link converter 18 has a line-side line converter module 21, a current link choke 22 and a machine-side power converter module 23. The DC link choke 22 is designed in a HTSL design and is supplied with cryogenic coolant together with the line-side power converter module 21 and the machine-side power converter module 23 by means of the cryosupply device 3.

The further motor 19 is also of HTSL design and is supported by means of superconducting bearings. The HTSL motor 19 and its superconducting bearings are supplied with cryotechnical coolant by means of the cryosupply device 3. In each of the other network branches of the upper network section 5 in FIG. 1 there is a converter transformer 12, which is designed like the converter transformer 12 arranged in the relevant network branch of the lower network section 4.

The two lower converter transformers 12 in FIG. 1 in the upper network section 5 are arranged together with a magnetic energy store 24 in a network branch.

The two magnetic energy stores 24 are each of HTSL design and are supplied with cryotechnical coolant by the cryosupply device 3.

The converter transformer 12 provided in the upper network branch in FIG. 1 of the upper network section 5 feeds via a voltage intermediate circuit 25 which, in its technical construction and in its structure, is connected to the voltage intermediate circuit 13 in the lower one in FIG Network section 4 coincides, several consumers, not shown in FIGURE 1.

The voltage intermediate circuit converter 25 and the upper HTSL magnetic memory 24 in FIG. 1 are connected to one another via an uninterruptible energy supply element 26. The energy supply element 26 is cooled by coolant provided by the cryosupply device 3.

FIGURES 2 to 9 show different configurations of the cryosupply device 3 of the electrical ship equipment.

The embodiment of the cryosupply device 3 shown in FIGURE 2 is designed as a central cooling system. A cooling system or air liquefaction system 27 belongs to this cryosupply device 3. Liquid nitrogen is generated in this cooling or air liquefaction system 27 and introduced into a collecting container 28 via insulated lines. HTSL transformers 29, HTSL generators 30, HTSL current limiters 31, HTSL motors 32 and other components 33 of the ship's electrical equipment described above are supplied with cryotechnical coolant from the collecting container 28 via insulated lines. An insulated header line provided downstream of the components mentioned leads the cryotechnical coolant via components 34 of the electrical ship's equipment that are only to be cooled to a higher temperature to a further header tank 35, in which the gaseous nitrogen can be stored before it is returned to the cooling or air liquefaction system 27 is initiated. The cryosupply device 3 described above with reference to FIGURE 2 is not designed redundantly and has a closed circuit for the cryotechnical coolant.

The embodiment of the cryosupply device 3 shown in FIG. 3 differs from that shown in FIG. This is due to the fact that it is designed to be redundant and accordingly has two cooling or air liquefaction systems 27a, 27b, two collecting tanks 28a, 28b for liquid nitrogen and two collecting tanks 35a, 35b for gaseous nitrogen, and correspondingly two insulated line systems.

The embodiment of the cryosupply device 3 shown in FIG. 4 differs from that shown in FIG. 2 in that the coolant circuit is designed to be open, with a store 36 for liquid nitrogen being provided instead of a cooling or air liquefaction system 27 and a collecting container 28, from which the liquid nitrogen is removed via insulated pipes and fed to the HTSL parts to be cooled and the other parts to be cooled. Downstream of the parts to be cooled, the then gaseous nitrogen escapes into the atmosphere.

The redundant embodiment of the cryosupply device 3 shown in FIG. 5 differs from that described with reference to FIG. 3 in that only HTSL transformers 29, HTSL generators 30, HTSL current limiters 31 and HTSL motors 32 are supplied with cryotechnical coolant.

FIGURE 6 shows a cryosupply device 3 which has a centrally designed partial cooling system 37 and a decentrally designed partial cooling system 38.

The centrally designed partial cooling system 37 corresponds in terms of its structure and its function to that of FIG

FIGURE 2 of the cryosupply device 3 described in more detail. The decentralized partial cooling system 38 of the cryosupply device 3 shown in FIUGR 6 has two refrigerators 39a, 39b which are provided for cooling an HTSL motor 32 assigned to a ship's propeller. Accordingly, the decentralized partial cooling system 38 is redundant. FIGURE 7 shows a decentralized cryosupply device 3, which has two non-redundant, in each case centrally designed partial cooling systems 37, each of which corresponds to the cryosupply device 3 explained with reference to FIGURE 3.

A decentralized cryosupply device 3 shown in FIG. 8 has six refrigerators 39 in the exemplary embodiment shown, by means of which an HTSL transformer 29 with associated components 40, an HTSL generator 30, an HTSL motor 32, and a first HTSL current limiter 31 second HTSL current limiter 31 and a HTSL power cable 41, are supplied with cryogenic coolant. The cryosupply device 3 shown in FIGURE 8 is not designed to be redundant.

The cryosupply device 3 shown in FIG. 9 differs from the one shown in FIG. 8 in that it is designed redundantly and two refrigerators 39a, 39b are assigned to each element to be cooled.

An electrical ship equipment shown in FIGURE 10 with performance data has two identically configured network sections 42, 43 which can be coupled to one another via a HTSL current limiter 44. Each network section 42 or 43 has three HTSL generators, each of which has a nominal power output of 14 MVA. Furthermore, each of the two network sections 42, 43 has a HTSL propeller motor 46, by means of which a ship's propeller 47 can be driven.

The magnet windings of the six HTSL generators 45 and the two HTSL propeller motors 46 are cooled to 25 K; a cryogenic cooling output of 200 W is required per HTSL generator 45, a cryogenic output of 300 W is required per HTSL propeller motor 46. In total, the cooling of the six HTSL generators 45 and the two HTSL propeller motors 46 results in a cryogenic cooling capacity of 1800 W. In each network section 42 or 43, four HTSL converter transformers with a nominal output of 9.2 MVA each are provided for the HTSL propeller motor 46, which supply the HTSL propeller motor via four converters 49.

In addition, seven HTSL distribution transformers 50 are provided in each network section 42 or 43, by means of which further consumers or the like, not shown in FIG. be supplied. Of the seven HTSL distribution transformers 50 per network section 42 or 43, three have a nominal power of 1.8 MVA, three have a nominal power of 2.2 MVA and one has a nominal power of 4.4 MVA.

The HTSL current limiter 44 provided between the two network sections 42, 43 has a maximum load flow of 28 MVA.

The HTSL current limiter 44, the eight HTSL converter transformers 48 and the fourteen HTSL distribution transformers 50 are each cooled to a temperature of 77 K.

For the eight HTSL converter transformers 48, the cryogenic cooling capacity to be installed is 9500 W, i.e. a total of 76000 W, for the six HTSL distribution transformers with a nominal output of 1.8 MVA each a cryogenic cooling capacity of 3000 W to be installed, thus a total of 18000 W, one for the six HTSL distribution transformers 50 with a nominal output of 2.2 MVA Installed cryogenic cooling capacity of 3500 W each, thus a total of 21000 W, for the two HTSL distribution transformers with a nominal output of 4.4 MVA, a cryogenic cooling capacity of 6000 W each, thus a total of 12000 W, and one for the HTSL current limiter 44 installing cooling capacity of 1000 W.

The total cryogenic cooling capacity to be installed for the components to be cooled to 77 K thus amounts to a total of 128000 W. cπ cπ tr Hi rr DJ φ σ N _ <_ tr »ω <lw tr rt N <x
