Description

[0001] METHOD FOR CONTROLLING POWER PLANT [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control method of a power plant, and more particularly, to a control method of a power plant that can be used as a power plant by connecting a generator to a main engine provided in a used floating propulsion body or a waste suspended propulsion body.

Land-based power plants, whether using fossil fuels or nuclear power, can cause serious environmental damage to nearby residents who are set up by natural disasters such as environmental pollution and earthquakes, and the recent NIMS phenomenon And selfish behavior that opposes unprofitable activities in the area where he / she belongs).

Therefore, recent power generation facilities are attracting attention for floating power generation facilities installed on the sea rather than on-site power generation facilities, which are difficult to select installation sites.

Floating power generation facilities are useful facilities in that they can supply power by providing power generation facilities in a short period of time in countries such as the islands or marine structures that have difficulties in supplying or receiving electricity.

Such floating power generation facilities include floating thermal power generation facilities, floating combined-cycle power generation facilities, and floating nuclear power generation facilities.

Among them, the floating power plant or the combined-cycle power generation facility allows one power plant to be installed in one propulsion unit in consideration of the mobility and economy of the propulsion body. This is possible because the size of boilers and gas turbines, which are heat sources for floating thermal power and combined-cycle power generation, is smaller than that of nuclear power plants and auxiliary systems, which are heat sources of nuclear power generation.

Floating type nuclear power plants are very heavy and bulky as well as have lots of sites to be installed, so that the facilities that constitute each plant are very heavy, , Followed by many technical constraints.

On the other hand, large vessels such as waste oil tankers, waste container ships, or pulmonary cargo vessels, which can not be operated any longer due to a shortage of the life span or the like, can greatly damage the marine environment and can discharge a large amount of pollutants. It should be treated promptly without neglect.

A common treatment of these vessels is to dismantle the vessel. That is, the operator takes the welding cutter and climbs up the ship to cut the part of the ship one by one while the waste ship is moved to the shore as much as possible.

Unlike the above-mentioned method of treating the ship, it is also used for the purpose of sinking used vessels or used vessels in the sea to replace artificial reeds, or to incinerate garbage using a waste ship.

However, this method has not been able to efficiently use the existing structure installed on the ship. Used or abandoned ships are equipped with engines that are used for propulsion and power generation of the ship. If they can generate electricity by using this engine, they can use the ship of the second-hand ship or the ship of the second ship as it is and minimize the installation of additional facilities. .

In addition, it is possible to minimize the time and cost required to convert a ship to a power generation facility, and it is possible to utilize a ship hull, and there is no difficulty in securing the installation site. A new alternative is needed.

Especially, it is required to control the electric power generated from the second-hand ship or the second ship to be efficiently used.

In order to fully understand the present invention, operational advantages of the present invention, and objects achieved by the practice of the present invention, reference should be made to the accompanying drawings and the accompanying drawings which illustrate preferred embodiments of the present invention.

Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

In the present embodiment, the used propellant or the waste propellant can be used as an LNG carrier, an oil tanker, a chemical carrier, a container ship, a cruise ship, an LPG carrier, a bulk carrier, offshore support vessels, FPSOs, semi-submersible rigs or jack-up rigs, or pulmonary propellants.

In addition, in the present embodiment, the waste propellant includes not only a case where a vessel or the like is damaged to such an extent that it can not be operated, but also a vessel which can be operated but is discarded due to management reasons or the like.

In the present embodiment, examples of the used propellant or the waste propellant include a semi-submerged league or a jack-up league. Although strictly speaking, engines provided in semi-submersible leagues or jack-up leagues are not used for propulsion for navigation, but in this embodiment, semi-submerged leagues or jack- As a propellant.

In this embodiment, the generator may be installed in a space separately provided for the used propellant or the waste propellant. The space provided separately in this embodiment may be a space in which the propeller shaft is separated and secured when the propeller shaft is separated from the engine room.

In addition, if the propeller shaft is not separated from the engine room, it may be a space obtained by removing the peripheral structure of the main engine, or may be a space secured by installing a separate frame support without removing the peripheral structure of the main engine.

1 is a view schematically showing a power plant according to an embodiment of the present invention.

As shown in this figure, the power generation plant according to the present embodiment includes an engine 10 provided in a used propulsion unit or a waste propulsion unit, and an engine 10 connected to the engine 10 to generate electricity to use a second propulsion unit or a waste propulsion unit as a power plant An additional power generation unit 30 provided in the propulsion unit for generating electricity separately from the power generator 20 and a power transmission unit 40 provided in the propulsion unit for transmitting electricity generated by the power generator 20, And an electric storage device 50 provided in the propulsion unit and storing electricity generated by the generator 20.

Hereinafter, for convenience of explanation, a description will be made with reference to a used propellant, and a main engine adopted as the present embodiment will be described together.

1, the engine 10 can be provided in the engine room ER of the stern section, and the engine 10 already installed in the used propulsion unit can be used as it is, Can be provided.

The engine 10 which can be adopted in the present embodiment will be described together with the engine provided in the second propulsion body.

Generally, the used propellant is provided with a main engine used for propulsion and an auxiliary engine used as power generation or auxiliary power, and the engine 10 to which the generator 20 of the present embodiment is connected may be the main engine.

In addition, the main engine may vary depending on the type of vessel being modified or the offshore structures such as semi-submersible leagues. For example, if the used propellant is a modified vessel, the class of the LNG carriers may be 210,000 m ³ , the tanker 300,000 dwt, the container ship 4,000 TEU, the LPG carrier 80,000 m ³ , and the bulk carrier 80,000 dwt. And the main engine may be an engine mounted on the above-mentioned used vessel.

However, the size of the above-mentioned propulsion chain ship is not limited, and can be selectively changed in consideration of required power demand and economical efficiency.

In 2012, shipwrecks in the world totaled 59 million DWT. In 2013, the ship is expected to be dismantled last year, and ships with less than 10 years of construction are going to be abandoned.

In the case of containerships, the 677TEU class container ship "Celina", which was constructed in 2002, was abolished. The average age of container ships less than 3,000 TEU was 19.4 years, down 2.9 years. The average age of abandoned vessels of less than 3,000 to 8,000 TEUs is decreasing by 3.8 years to 20.0 years. The average age of abandoned vessels of very large crude oil carriers (VLCCs) of 200,000 DWT or less has fallen below 20 years this year. 22.8 years) and the average age of abolition of the Apramax class (21.4 years) is likely to fall below 20 years.

The main engines installed in the second propulsion are i) diesel engine, ii) steam turbine engine, iii) electric propulsion engine, iv) gas turbine engine, v) dual fuel engine, and vi) nuclear power engine.

Hereinafter, each of the engines used as the main engine will be described.

i) Diesel engines have a two-stroke low-speed engine, which is applied to medium / large sized vessels, and a four-stroke high-speed engine, which is applied to small vessels. The rotational power obtained from the main engine is transmitted to the propeller through the propeller shaft. The efficiency of the main engine is high because the revolutions per minute is high, but the propeller is efficient at low revs, so the reduction gear is installed in the propeller shaft to which the power is transmitted. The appropriate number of revolutions of the screw propeller in the commercial vessel is 80 to 150 rpm.

However, the direct connection between the main engine and the propeller in a diesel engine is limited to the case where the main engine is a large low-speed engine.

In addition, diesel engines are classified as high speed, medium speed and low speed according to the revolution per minute (rpm). The speed of the high-speed engine is 1,200 to 2,400 rpm, which is usually the upper limit of 3,500 horsepower per unit. The medium-speed engine has an output of about 10,000 to 10,000 rpm, and the output of the low-speed engine is designed so that its rotation speed coincides with the optimum rotation speed of the propeller. Large-size diesel engines are all low-speed engines with a rotation speed of less than 120rpm, with a typical output of between 5,000 and 45,000 horsepower.

In the present embodiment, when a used vessel (see FIG. 2) propelled by a large-size diesel engine is converted for power generation, the revolution per minute of a large-sized diesel engine required for power generation is low. 2, there is further provided a speed reducer 60 (see FIG. 2) between the large diesel engine and the generator 20 in order to increase the rotation speed per minute transmitted from the large diesel engine to the generator 20 do.

The four-stroke high-speed engine of the diesel engine can be used as the additional power generation engine 31 used to obtain additional power generation in the additional power generation section 30 described later. In addition, the four-stroke high-speed engine used for the additional power generation can utilize what is installed in a used vessel or a waste ship, or can newly install it.

ii) A steam turbine engine converts high-temperature and high-pressure gas into kinetic energy by causing the shaft to rotate by bumping against a large number of rotating blades connected to the shaft. The steam turbine engine is able to generate a strong force, and when it exceeds 30,000 horsepower per shaft, it is advantageous in terms of economic efficiency and reliability compared with diesel engine and was used as the main engine of the ship. For example, in the case of LNG carriers, most of the steam turbine engines were used as main engines before the 2000s.

Steam turbine engines used in commercial vessels produce 5,000 to 7,000 rpm for high pressure turbines and 3,000 to 5,000 rpm for low pressure turbines. As described above, since the propeller is efficient at a low rotation speed, a propeller shaft (PS) that transmits power when a steam turbine engine is used is equipped with a two-stage gear reducer or a three-stage gear reducer employing a planetary gear, .

In the case of steam turbine generation, 3,000 rpm is required for 50 Hz alternating current, and 3,600 rpm is required for 60 Hz alternating current.

In the present embodiment, when the second propulsion body equipped with the steam turbine engine is converted into a power plant, the engine 10 installed in the second propulsion unit is used, and the revolutions per minute of the steam turbine engine itself is required for power generation The number of revolutions can be satisfied.

The output frequency (Hz) of the alternator depends on the number of electrodes and the rotation speed. The speed corresponding to a specific frequency is called the synchronous speed, and there are several examples in Table 1 below.

Number of electrodes RPM (50 Hz) RPM (60 Hz) RPM (400 Hz) 2 3,000 3,600 24,000 4 1,500 1,800 12,000 6 1,000 1,200 8,000 8 750 900 6,000 10 600 720 4,800 12 500 600 4,000 14 428.6 514.3 3,429 16 375 450 3,000 18 333.3 400 2,667 20 300 360 2,400 40 150 180 1,200

Accordingly, when the steam turbine engine is mounted on the engine of the modified second-hand propulsion unit, the generator 20 is directly connected to the steam turbine engine mounted on the engine 10 without the reduction gear mounted thereon It can develop.

Specifically, since the low-pressure turbine generates a rotation speed of about 3,000 to 5,000 rpm, when the frequencies 50 Hz and 60 Hz are selected, the generator 20 can be directly connected to the steam turbine engine without the reduction gear.

In the high-pressure turbine, the rotation speed is about 5,000 to 7,000 rpm. When the frequency is selected as 400 Hz, the generator 20 can be directly connected to the steam turbine engine like the low-pressure turbine. However, if the frequency of the high-pressure turbine is set to 50 Hz or 60 Hz, a reduction gear may be used to adjust the revolution per minute.

iii) Electric propulsion engines are mounted on LNG carriers or icebreakers and used for propulsion of ships. The electric propulsion engine is used for producing electricity, the electricity produced by the electric propulsion engine is supplied to the propulsion motor, and the propulsion shaft of the ship is connected to the propulsion motor to propel the ship.

As the electric propulsion engine, a four-stroke high-speed engine, a steam turbine engine, or a gas turbine engine may be used.

Since the generator is installed in the second propulsion unit propelled by the electric propulsion engine, there is no need to install a separate generator, and the pre-installed equipment can be used as it is.

iv) The gas turbine engine differs from the above-mentioned steam turbine engine in that it uses non-steam gas as the working fluid and does not require the boiler, reactor, etc. necessary in the steam turbine.

Since the gas turbine engine is applied to modern warships, LNG carriers, cruise ships, etc., which are mainstream lightweight vessels of less than 10,000 tons, the above-mentioned conventional warships, used LNG carriers, and used cruise ships can be used as used propellants of this embodiment.

In this embodiment, when the second propulsion body equipped with the gas turbine engine is retrofitted, the generator 20 can be directly connected to the gas turbine engine without a reduction gear in accordance with the frequency (Hz) like the steam turbine engine.

v) A dual fuel engine can propel a ship by injecting diesel oil and liquefied gas selectively into the engine, for example, a dual fuel diesel electric (DFDE) engine and an ME-GI engine.

The DFDE engine uses liquefied gas vaporized from LNG to obtain power by injecting it into the engine, and then power is generated through the generator to turn the motor to obtain propulsive power. In other words, it is electric propulsion vessel that differs from ship using diesel engine and steam turbine engine.

The DFDE engine is not an engine that converts the chemical energy of a fuel into mechanical energy, but an engine that turns a motor (electric motor) by converting chemical energy into electrical energy.

Therefore, energy loss occurs in the energy conversion process, and the DFDE engine can not be enlarged to a medium-speed engine. Therefore, it is difficult to apply it to general commercial ships (cap-size bulk carriers, VLCC, etc.).

However, in this embodiment, when a ship equipped with a DFDE engine is modified as a main engine, a generator connected to a DFDE engine is already installed in a ship propelled by a DFDE engine. Therefore, a generator provided can be used without installing a separate generator There is an advantage. On the other hand, unlike the ME-GI engine described below, the DFDE engine can be operated 100% solely by liquefied gas itself without diesel fuel.

The ME-GI engine is an engine developed to overcome these shortcomings of the DFDE engine. Unlike the DFDE engine, the ME-GI engine is a low-speed engine type used in general marine vessels. It does not require a system such as a generator and a motor.

In the present embodiment, when the secondary vessel equipped with the ME-GI engine is converted to power generation, the number of rotations per minute for obtaining the required power generation capacity as in the above-described diesel engine is insufficient, A speed increasing device 60 (see Fig. 2) can be provided.

vi) Nuclear propulsion engines are steam turbines or propulsion engines equipped with nuclear reactors instead of boilers in ships, and ships are mounted on icebreakers.

An ice breaker is an ice breaker that is used to break the ice of a water body in an ice-covered freezing area and form a passage. The ice breaker is an inward-facing type and an oceanic type, depending on the water area. The ocean type is large, and the nuclear icebreaker in Russia is a super large ship of 16,000 tons. The American model also has a propeller on the athlete so that the water below the ice surface is excluded to facilitate ice breaking. There are two types of European type icebearing icebreakers and icebreakers by colliding athletes on the ice surface.

In this embodiment, when converting an ice-breaking line driven by a nuclear propulsion engine to a used propulsion unit, the number of revolutions per minute necessary for the power generation capacity can be obtained by the nuclear power engine itself. Therefore, as shown in FIG. 1, Generator 20 can be directly connected.

1, the main engine that can directly connect the generator 20 to the engine 10 without the gearbox 60 is a steam turbine engine, a gas turbine engine, an electric propulsion engine, As the fuel engine, there are DFDE engine and nuclear power engine.

However, since the electric propulsion engine or the DFDE engine has a generator already installed in the used propulsion body, there is an advantage that the work flow and cost for installing the separate generator 20 can be reduced.

The generator 20 can be directly connected to the main engine adopted as the engine 10 without the speed reducer 60 (see Fig. 2), as shown in Fig. In this case, the main engine may be a steam turbine engine, a gas turbine engine, an electric propulsion engine, a DFDE engine, or a nuclear power engine as described above.

In this embodiment, the generator 20 may be an alternator, and the frequency of the power produced by the generator 20 may be 60 Hz or 50 Hz.

Further, when the generator 20 is connected to the engine 10, all or part of the propulsive shafts PS mounted on the second propulsive body can be separated. (PS) portion of the skeg (S) region and a propeller shaft (PS) portion disposed in the engine room (ER) region adjacent to the skeg (S), not separating the entire propulsive shaft ) Portion is advantageous in terms of work efficiency. In this case, the portion around the propulsion shaft (PS) of the region where the S (S) region and the engine room (ER) are in contact with each other is watertight. Further, since the propulsive shafts PS are provided in a plurality of unit shafts, the flanges for connecting the plurality of unit shafts to each other can be used as they are.

As shown in FIG. 1, the additional power generation unit 30 is provided in the hull of the second propulsion body, and separately generates electricity from the generator 20 connected to the main engine. That is, the additional power generation unit 30 is different from the above-described generator 20 in that the additional power generation unit 30 is not provided with a main engine used for propulsion.

In this embodiment, the additional power generation unit 30 may be provided in the interior of the hull of the second propulsion body or the upper deck UD as shown in FIG. In the present embodiment, the installation location of the additional power generation unit 30 is not limited to the above example, but may be an engine room ER, a bosun store, a fore peak tank And an after peak tank.

In this embodiment, the additional power generation unit 30 includes an additional power generation engine 31 that provides a rotational force necessary for power generation and an additional generator 32 that is connected to the additional power generation engine 31 to produce electricity.

The additional power generation engine 31 may adopt a generator engine installed in the second propulsion unit to be used for power generation of the second propulsion unit, or may use a new generator engine instead of the second generation engine.

In this embodiment, the additional power generation engine 31 may be provided in the interior of the hull, for example, in the cargo hold as shown in FIG. 1, or may be provided in the upper deck UD. Further, the additional power generation engine 31 may be provided in plural in consideration of the amount of power required in the coastal area where the present embodiment is disposed or the river-side region on the land.

Further, the additional power generation engine 31 of the present embodiment may be selected from a diesel engine, a steam turbine engine, and a gas turbine engine.

As shown in FIG. 1, the additional generator 32 is connected to the additional generator 32 and generates electric power separately from the generator 20. The additional generator 32 is connected to the additional generator 32, (UD).

In this embodiment, the additional generator 32 may be an alternator, such as the generator 20 described above, and the frequency of the power produced by the generator 20 may be 60 Hz or 50 Hz.

The additional generator 32 may also be a container generator.

When the additional power generation unit 30 is provided on the upper deck UD in this embodiment, the additional power generation engine 31 and the additional power generator 32 are exposed to the outside, Can be provided on the upper deck (UD).

The power transmission equipment 40 transports electric power produced by the generator 20 or the additional generator 32, and may be provided on the hull, as shown in Fig.

The transmission facility 40 in this embodiment is provided with a transmission cable 41 for transmitting electric power generated by the generator 20 or the additional generator 32 to a power demand site on the coast or the riverfront, And a transmission tower (42) for supporting the transmission cable (41).

The transmission cable 41 can connect the generator 20 and the transmission tower 42 when the generator 20 is provided in the engine room ER as shown in FIG. The additional generator 32 provided in the generator 32 or the upper deck UD can be connected to the transmission tower 42. [

The transmission cable 41 is supported by a mast (mast), a hose pipe (stern tube), and a stern tube (a cylindrical pipe which passes through the hull and extends to the outside of the hull) To the generator 20, the additional generator 32, or via the hole of the generator 20). In the present embodiment, the mast M includes a radar mast, a venting mast for discharging gas outboard, and the like.

1, the transmission tower 42 is provided on the upper deck UD and supports the transmission cable 41. The transmission tower 42 may be newly installed on the upper deck UD, May be used.

Specifically, a mast (M) and a residence (LQ) are basically installed in a used propulsion vessel. Examples of the mast include a radar mast and a venting mast. Since they are all protruded from the upper deck UD by a predetermined height, the number of transmission towers 42 to be newly installed can be reduced by using them.

In addition, since the residence port LQ has a predetermined height from the upper deck UD, it is also possible to support the power transmission cable 41 using a wall portion of the residence port LQ or the like.

Furthermore, since a plurality of lashing bridges 140 are provided on the upper deck UD of the container line, the lashing bridge 140 may be used as the transmission tower 42.

The electric storage device 50 is provided on the upper deck UD as shown in Fig. 1, and the electric power generated by the generator 20 or the additional generator 32 is stored. The electric power generated by the generator 20 or the additional generator 32 may be supplied directly to the electric power demanding place on the land or sea via the transmission cable 41 and the transmission tower 42, Lt; / RTI > The demand for land can be supplied to homes or industrial complexes if blackout or power supply of the offshore power plant is insufficient. The demand for electricity on the sea is moored on the sea or on the sea, and includes crude oil and LNG Examples are ships and floating offshore structures that are loaded with liquefied gas.

In the present embodiment, the electric storage device 50 charges the electricity when the generator 20 or the additional generator 32 generates a large amount of electricity, and supplies the stored electricity to the customer when the power consumption is large, .

In this embodiment, the electric storage device 50 may be selectively applied depending on the output and the capacity. For example, when an electric storage device using a secondary battery, a flow battery, and a liquid electrolyte are stored in an external tank, when the battery is charged and discharged, the active material flows into the battery through the pump, A superconducting magnetic energy storage device (SMES) may be used as the battery.

Fig. 2 is a view schematically showing the addition of an accelerator between the engine and the generator in the power generation plant shown in Fig. 1. Fig.

The engine employed as the main engine in the engine 10 shown in Fig. 2 may be a diesel engine, and may be a low speed large diesel engine among diesel engines. As described above, the efficiency of the main engine is high due to the high revolutions per minute, but the efficiency of the propeller is good at low revolutions.

Also, the direct connection between the main engine and the propeller in a diesel engine is limited to the case where the main engine is a large low-speed engine. Large-size diesel engines are all low-speed engines with a rotation speed of less than 120rpm, with a typical output of between 5,000 and 45,000 horsepower.

In this embodiment, when the used propellant propelled by the large diesel engine is converted to the power generation, the revolution per minute of the large diesel engine required to generate electricity is low. Therefore, as shown in FIG. 2, a gearbox 60 is further provided between the large diesel engine and the generator 20 in order to increase the number of revolutions per minute transmitted from the large diesel engine to the generator 20.

25 is a use state diagram of the power generation plant according to the present embodiment.

As shown in Fig. 25, in this embodiment, the power plant P installed on the land is moored on the sea floor J adjacent to the sea, It is possible to supply electric energy to a power consumer quickly.

In this embodiment, the power plant P may include a nuclear power plant, a thermal power plant, or a combined-cycle power plant, and the combined-cycle power plant may use LNG or diesel as fuel.

The present embodiment can use a pre-installed storage tank or store a crude oil, engine fuel, LNG and the like in a storage tank by providing a storage tank in an empty space of the hull, and store crude oil, LNG, It can be supplied to the destination.

Since the present embodiment can maintain the state moored on the seawall J, a separate line connected to the manifold installed on the hull can be provided on the seawall J, and a line provided on the seawall J can be connected to a land- Only the line to be installed on the ground.

Also, as an example of a used propulsion system in which the present embodiment is applied, a cargo pump for unloading crude oil is installed in an oil tanker, so that crude oil or fuel can be pumped and supplied to an onshore site by using the cargo pump.

On the other hand, this embodiment is more effective when the power plant P is provided on the land, which can use the power network of the power plant P provided on the land as it is and can reduce the cost and time required for constructing the power network, This is because power can be supplied to the power consuming place instead of the power plant P when the power plant P can not operate due to failure or the like.

Furthermore, this embodiment can be applied to a case where there is no power plant P on the land, and it is not limited to the coast, but may be arranged on a river side or the like.

26 is a block diagram schematically illustrating a process in which electric power produced by the main engine or the additional power generation unit is supplied to an in-line voltage or a power demand destination through the control of the transformer in this embodiment.

The present embodiment can connect the generator 20 to the main engine 10 or generate electric power through the additional electric power generating unit 60 as described above and the generated electric power can be supplied to the transformer 25, may be used as in-ship voltage, supplied to a power consumer, or stored in an electrical storage device 50. [

In other words, in the present embodiment, the electric power produced by the generator 20 and the additional electric power generating unit 60 is an AC voltage, and the voltage supplied to the inside of the ship may be different from the voltage supplied to the outside electric power consumers.

In general, 440V (60Hz) is the basic power produced by auxiliary generator engine and auxiliary generator, not main propulsion engine. In other cases there is 380V (50Hz), 3.3kV or 6.6kV can be used when there is a machine using a large power in a ship, and 55V or 24V can be adopted in a dangerous area such as a high temperature or a dark place.

Most of the power used on land, such as power plants, is not 220V, 110V, or 380V.

Therefore, a transformer 25 is required to supply the electric power produced by connecting the generator 20 to the main engine 10 or the electric power generated by the additional electric power generating unit 60 to the electric power consumers on the land. Of course, the 440V is reduced to 220V in order to supply a voltage to a bulb or the like used in a ship, but it is not enough to supply a large amount of electric power to the onshore power demand site as in the present embodiment with a small capacity. That is, a transformer installed in a pre-suspended propulsion body or a pulverized propulsion body can not perform a multi-power transmission operation to a power consumer such as in-line voltage or onshore, as in the present embodiment.

This embodiment can solve this problem by providing a large-capacity transformer 25 in the clearance space of the ship or by providing a plurality of transformers 25. [

On the other hand, the power generated by the auxiliary generator in the conventional ship is directly distributed through the cable through the main switchboard without passing through the transmission line, because the voltage is lower than that on the land.

The present embodiment further includes the above-described transmission facility 40 (see FIG. 1) provided on the hull because the large-capacity electric power of the present embodiment can not be supplied not only in the ship but also outboard of the ship through the conventional switchboard and cable. That is, the present embodiment can supply power directly to the inside of the ship as well as the inside of the ship using a transmission line such as the transmission cable 41 (see Fig. 1).

The present embodiment can store the electric power produced by the generator 20 or the additional electric power generating unit 60 in the above-described electric storage device 50 (see FIG. 1). Accordingly, when the power generation amount of the generator 20 or the additional power generation unit 60 is larger than the required power generation amount, the electricity is stored in the electric storage device 50, and when the power demand of the power demanding place is large, And the supply gap can be efficiently compensated.

Finally, in the present embodiment, when the engine employed in the main engine 10 is a two-stroke diesel engine or an ME-GI engine, the above-described accelerator is supplied to the main engine 10 in order to satisfy the rotation speed required in the generator 20, And the generator (20).

In the present embodiment, a plurality of generators 20 may be connected to one main engine 10, as shown in Fig.

In this embodiment, since the engine adopted as the main engine 10 is mostly a large engine, the engine horsepower is much higher than that of other small and medium sized ships, and the stability of the main engine 10 itself is considerably high. Therefore, it is economically inefficient to connect a single generator 20 to the main engine 10 for power generation.

27, a plurality of generators 20 may be connected to one main engine 10, and each of the generators 20 may be connected to the generator 20 and the main engine 10. In this case, Can be independently generated by the clutch C 'provided between the clutches (10).

3) serves to selectively connect or disconnect the engine 10 and the propeller shaft or the engine and the generator 20. [ However, in the clutch C 'of this embodiment, since the plurality of generators 20 are connected to one main engine 10, the power transmitted to each of the generators 20 in addition to the role of the above- Connect or block.

The frequencies output from the respective generators 20 can be synchronized by the frequency controller 80 described above.

In this embodiment, as shown in FIG. 4, a plurality of main engines 10 may be provided, and the generators 20 may be connected to each main engine 10 to generate electric power. At this time, the number of revolutions per minute (rpm) of each main engine 10 and the frequency (Hz) of each generator 20 are synchronized by the rotation speed control unit 70 and the frequency control unit 80 .

Fig. 28 is an operation diagram of the operational state of Fig. 27, that is, an operation diagram in which the power output from the main engine 10 in Fig. 27 (a) is transmitted to the generator 20 disposed at the upper portion via the clutch C '.

In the present embodiment, when it is necessary to operate the generator 20 disposed at the top of the pair of generators 20 without rotating the propeller shaft, as shown in Fig. 28, the main engine 10 and the propeller shaft are connected The gears are cut off from each other.

It is necessary to shut off the generator 20 disposed below the pair of generators 20 because the gears connected to the shaft of the main engine 10 and the gears connected to the shaft of the generator 20 are separated from each other Lt; / RTI >

Finally, the power output from the main engine 10 is placed between the gears connected to the shaft of the main engine 10 and the gears connected to the generator 20 disposed at the top of the pair of generators 20 Can be transmitted to gears disposed on the upper side by engaging the gears to be engaged with each other.

As described above, the present embodiment can reduce the cost of constructing the power plant by reducing power consumption by connecting the generator to the engine provided in the used propulsion unit or the waste propulsion unit, It is possible to supply power quickly in case of a power shortage or a power supply short-circuit accident.

Also, the present embodiment can efficiently control the power generated by the used floating propulsion body or the suspended propulsion body to be supplied to the in-ship power and electric power demanding sites.
