When through be directly connected to the boat-carrying network come in ship repacking this type of when connecting on the bank, the switch that connects on the bank that is used for reequiping at ship and the problem of watch-dog exist.This generally also need be to the intervention of existing switch and watch-dog, and so be expensive, and usually owing to the space reason still is impossible.
Known the use of the current converter that is used for being connected on the ship that is positioned at ship on the bank, so that will become to have the frequency of boat-carrying network and the electric current of voltage by the current conversion that connects supply on the bank with the frequency different and voltage with the boat-carrying network from WO 2007/060244 A2 and WO 2007/060189 A1.Yet, do not have the available current transducer of the ship boat-carrying that is suitable for this purpose sometimes.
Summary of the invention
The objective of the invention is to specify a kind of method that is used for to the boat-carrying power network supply external energy of ship, can avoid the problems referred to above with this method.Especially, this method should be able to be carried out under not to the situation as any major change of the existing switch of essential ship boat-carrying and surveillance equipment.Another object of the present invention is to specify a kind of ship, utilizes this ship, might proceed to the supply of this type of external energy of the boat-carrying network of ship.In addition, will specify a kind of method, and, can in ship, reequip the external energy supply with low relatively expense through this method.
By realizing purpose about said method like claim 1 method required for protection.Realize purpose by the ship of characteristic about said ship with claim 10.A kind of method that is used to reequip the external energy supply is the theme of claim 16.Favourable development is the theme that the subclaim under every kind of situation requires.
In the inventive method that is used for to the boat-carrying power network supply external energy of ship; Wherein ship is a characteristic with motor (electrical machine); This motor is driven by at least one energy source of ship boat-carrying for the energy of ship supply its oneself time; For boat-carrying network provisioning external energy to ship; This motor is operated as generator, and uses the electric current from least one energy source of outboard face to drive this motor in this case, makes frequency and voltage that its generation has the boat-carrying network so that be fed to the electric current in the boat-carrying network.
Therefore, the supply that the motor that is used to diverse purpose on the ship that is present in ship and during oneself energy supply of ship is used for external energy.Use electric current to drive this motor directly or indirectly, and it is used for the voltage of the electric current of being sent by this energy source is become to have the frequency of boat-carrying network and the electric current of voltage with frequency inverted in this case from least one energy source of outboard face.This makes the existing switch and the surveillance equipment of motor of ship boat-carrying can be used in the external energy supply, and making does not need bigger change or the upgrading in the ship for this purpose.This motor is also realized the boat-carrying network and is arranged in the electrical separation between the energy source of outboard face.This means in the energy source that is arranged in the outboard face or boat-carrying network and be arranged in the overvoltage event in being electrically connected between the energy source of outboard face and other influence (it has destructiveness to the boat-carrying network) is not transferred to the boat-carrying network and vice versa.
Motor can comprise any motor (that is, engine or generator) of suitably being confirmed the ship boat-carrying of size with respect to its power basically.When for its own energy of ship supply, motor can be come electrically by at least one energy source of ship boat-carrying or also mechanically driving in this case.Use driven by power, can be directly or via the boat-carrying network from the energy source power supplied.
Be positioned at the energy source that energy source on the ship of ship can comprise any kind, it produces mechanical energy or electric energy from main energy carrier (for example, nature or artificial fuel, solar energy, wind) or auxiliary energy carrier (for example, the used heat of machine).Its example is Diesel engine, combustion gas turbine or also has steam turbine (latter for example combines with waste heat utilization system), wherein comprises the generator that is driven thus to generate electricity in case of necessity.
Preferably; Use the motor of ship boat-carrying; It is used as generator for the energy of ship supply its oneself time; Especially as the generator of waste heat utilization system or as reactive power generator, because these machines are confirmed size by the needs according to the power requirement of external energy supply, and energy supply manipulate externally in addition.
As replacement, preferably use motor, it is used as the equipment that is used to drive the ship boat-carrying for its own energy of ship supply the time, in particular for the engine of driving athwartships propeller or pump.
The energy source that is positioned at the outboard face can comprise the energy source of any kind; It from main energy carrier (for example; Nature or artificial fuel) or from auxiliary energy carrier generation electric energy; Such as for example be positioned at land electric power generating plant, the power station of floating, float harbor power supply or offshore platforms, wherein latter two has generator that is used to generate electricity and the internal combustion engine (for example gas turbine or Diesel engine) that drives said generator usually.
Motor can have the electric current that is used to utilize exterior source of energy in each case drove and be used to produce the power that is used for the boat-carrying network to it independent winding system.Yet; According to particularly advantageous development; To come drive motors by (separately) electric motor that the external energy of the boat-carrying network that is used for ship is supplied; Electric current by from the energy source that is arranged in the outboard face is operated said motor, and wherein the electric motor drive motors makes the latter produce and has the frequency of boat-carrying network and the electric current of voltage.
When electric motor is supplied to ship with the energy with oneself and only is coupled to motor with supply during external energy from the motor de, electric motor needn't be moved for the energy of ship supply its oneself time simultaneously, can avoid energy loss thus.
Preferably; For boat-carrying network provisioning external energy to ship; Electric motor is come drive motors via the power delivery element, and this power delivery element moves the rotation that converts motor to the rotation of electric motor and moves so that produce the electric current with the required frequency of boat-carrying network and voltage.This makes it possible to model engine (for example asynchronous motor) cheaply is used for electric motor.The rotary speed of the motor that the frequency that can made the rotary speed of electric motor be suitable for producing to have the boat-carrying network by the power delivery element in this case and the electric current of voltage are required.
The power delivery element preferably includes gear drive.In the low-down replacement development of cost, can also chain be driven or be with to drive to be used for the power delivery element.If can change gearratio to the power delivery element, the flexible operation ground that electric motor is directed against use the electric current from the different voltages of having of different-energy source and frequency to carry out is suitable for having the voltage of boat-carrying network and the required speed of electric current of frequency in the motor side generation.
Voltage interruption for fear of the boat-carrying network of the dead electricity (blackout) that from the conversion of its oneself energy supply to external energy supply the time, just in time passes to ship, the Phase synchronization that preferably makes the boat-carrying network voltage to before the conversion of own energy supply to external energy supply by the phase place of the voltage of motor generation.This can accomplish for the generator place that moves to ship supplying energy (for example, through adapting to the speed and the torque of the Diesel engine that drives boat-carrying network generator) intervenes to the boat-carrying network through closed loop appreciated by those skilled in the art or open loop control.
If before the conversion of its oneself energy supply to external energy supply, make the phase place of Phase synchronization to the boat-carrying network voltage of the voltage that produces by motor on the contrary, then can avoid this type of open loop or closed-loop control intervention.If by utilizing slide drive to come the asynchronous motor of drive motors to come drive motors; Then to repeat a little etc. that pending connection (in this junction, the phase place and the Phase synchronization of boat-carrying network voltage of the voltage that is produced by motor) comes to make this point with especially simple mode be possible through accurately making temporal one.In other cases; For example; Come under the situation of drive motors by synchronous machine therein, can be for example carry out by the open loop of the phase place of the electric current that is fed to electric motor or closed-loop control that this is synchronous by means of the current converter that connects from the electric motor upper reaches.
If the electric motor by being used for the external energy supply is come drive motors, the speed that also might be through mechanically making motor and the speed of electric motor mutually synchronization mutually realize that this is synchronous.This can accomplish in first step usually; In first step; Through by from the motor of the current drives of boat-carrying network with by starting independently of each other from the electric motor of the current drives of the energy source that is arranged in the outboard face or operate, with motor and electric motor de each other mechanically.So, come drive motors with the frequency and the phase place of boat-carrying network.Subsequently, in second step, make motor and electric motor in mutually synchronization mutually mechanically aspect its speed.This can accomplish with the mechanical couplings of motor and electric motor through the switch shaft coupling between the motor of closed arrangement in electric motor, and said switch shaft coupling preferably is embodied as friction coupling for this purpose.So it is unessential being used for the phase place of voltage and current of driving electric engine.
This method is suitable for making synchronously and also has the two speed synchronization of asynchronous machine.Can also make synchronous machine and asynchronous machine synchronous under the situation of problem having no.When repacking external energy supply, this method means need be to the intervention of existing synchronizing sequence.
At network, the motor of ship be used for the ship of the present invention of at least one energy source of the ship boat-carrying of drive motors for the energy of ship supply its oneself time with boat-carrying; Motor can be operated as the generator that is used for to the boat-carrying network provisioning external energy of ship; And when operating by this way; Motor is implemented as and can be used for driving from the electric current of at least one energy source of face overboard, makes frequency and voltage that its generation has the boat-carrying network so that be fed to the electric current in the boat-carrying network.
In this case, preferably motor is embodied as generator, especially as the generator of waste heat utilization system or as reactive power generator, it is used for power supplied to be used for oneself energy supply of ship.
Alternatively, can motor be embodied as engine, equipment, especially athwartships propeller or the pump of its driving ship boat-carrying for its own energy of ship supply the time.
Advantageously; Ship comprises and is used for drive motors so that to the electric motor of the boat-carrying network provisioning external energy of ship oneself; Wherein this electric motor can be connected via the energy source that is electrically connected with being arranged in the outboard face; And be implemented as and can be used for since then the electric current of energy source and operate; Wherein this electric motor is implemented as and can be coupled or be coupled to motor, makes when it is operated with this electric current, has the frequency of boat-carrying network and the electric current of voltage by the motor generation of its driving.
In favourable development, shaft coupling (especially in an embodiment as friction coupling) can be used for that electric motor goes to or from the operational coupled or the de of motor.Utilization is implemented as the shaft coupling (having explained like preceding text) of friction coupling, can advantageous particularly ground actuating motor and the mechanical synchronization of the speed of electric motor.
According to particularly advantageous development, said ship comprises the power delivery element, and transmission device especially moves so that the rotation that converts the required motor of the electric current that produces frequency with boat-carrying network and voltage to is moved in the rotation of electric motor.
Be applicable to ship of the present invention and each corresponding favourable development thereof to method of the present invention and the described advantage of favourable development thereof with being equal to.
In the inventive method that is used for reequiping the external energy supply of the boat-carrying power network that is used for ship at ship; Wherein gear has motor; This motor is driven by at least one energy source of ship boat-carrying for the energy of ship supply its oneself time; And electric motor is installed in the ship, and it is coupled maybe can be coupled to motor so that it is driven, and wherein electric motor can be connected at least one energy source that is arranged in the outboard face via being electrically connected; And be implemented as can origin since then the power of energy source drive; Wherein this electric motor is implemented as and is coupled maybe and can be coupled to motor, makes when it is operated with this electric current, has the frequency of boat-carrying network and the electric current of voltage by the motor generation of its driving.
For this external energy supply of repacking, this means the electric motor that only must reequip the motor that is used for driving ship.In this case, can use asynchronous motor cheaply.Can use the existing monitoring and the switchgear of motor, make it possible to avoid bigger change or the upgrading in the ship with respect to this kind equipment.Reequip the external energy supply to compare this be very big advantage with being connected to exterior source of energy direct with the boat-carrying network; Because making, this repacking of the costliness need additional supervision and switchgear in the ship does not usually have the space that is used for this additional supervision and switchgear.Be used for piloting engine of motor if in ship, existed, then this can also replace with electric motor, thus, even can further reduce the cost of the aspect, space that is used to reequip electric motor.

Embodiment
Comprise with the ship shown in the simplified way among Fig. 1: boat-carrying network with rated voltage U1 and rated frequency f1; Be connected to a plurality of generators 4 of boat-carrying network 2, and each generator 4 is driven so that produce the power that is used for boat-carrying network 2 by a Diesel engine 3 all; And the load 5 that is connected to boat-carrying network 2.Form with reactive power machine (reactive power generator) 6 is used to produce the reactive power that is used for boat-carrying network 2 via the motor that series reactor 21 is connected to boat-carrying network 2.As replacement, can reactive power machine 6 be connected directly to boat-carrying network 2.
Usually the reactive power machine 6 that is implemented as synchronized engine is assemblies of shaft generator/engine system 20, and it also comprises shaft generator/engine 23, field rectifier 24, starting current transducer 25, machine side current converter 26 and the network side current converter 27 that is coupled to propeller shaft 22 except series reactor 21.
When being its own energy of ship 1 supply, Diesel engine 3 serves as the energy supply on the other hand and drives generator 4, and this generator 4 synchronized with each other is presented the electric current with voltage U 1 and frequency f 1 in boat-carrying network 2.Master machine 28 (for example; Large-sized diesel motor) thus another energy source of form drives propeller shaft 22 and driving shaft generator 23; Its generation has the voltage U 3 that is different from the boat-carrying network and the electric current of frequency f 3; This electric current is converted to the voltage U 1 with boat-carrying network and the electric current of frequency f 1 by transducer 26,27, and is fed in the boat-carrying network 2 via series reactor 21.Because shaft generator 23 can not be supplied any reactive power, so this must be provided by reactive power machine 6.In this case, reactive power machine 6 is used respectively from boat-carrying network 2 or from the electric current of shaft generator 23 and is operated.In this case, reactive power machine 6 quilts are from engine 7 de.
In this case, employ open type switch (open switch) 14 to take place until the rising of reactive power machine 6 of the point that reaches network f1 via starting current transducer 26 and the electric current of network side current converter 27 from boat-carrying network 2.
For the boat-carrying network 2 supply external energies to ship, reactive power machine 6 is operated as the generator that produces effective power.For this reason, the shaft generator operation is stopped, and reactive power machine 6 and network 2 are isolated by switch 14.By means of circuit 11 electric motor 7 is connected to onshore network 12.Subsequently, reactive power machine 6 is coupled to electric motor 7 and drives by the latter.In this case, use electric current to come driving electric engine 7, and it drives reactive power machine 6 via transmission device 8, make its generation have the electric current of the voltage U 1 and the frequency f 1 of onshore network 2 with voltage U 2 and frequency f 2 from onshore network 12.
In this case; The gearratio of electric motor 7 and transmission device 8 is tuned to reactive power machine 6; Make electric motor 7 be used for that the electric current with voltage U 2 and frequency f 2 of automatic network 12 operates during; Drive reactive power machine 6, make it rotate with certain speed, its generation has the electric current of the voltage U 1 and the frequency f 1 of boat-carrying network 2 under this speed.
Voltage interruption for fear of the network of the transition period that is supplied to external energy supply from own energy in translate phase, must exist the while by one or more in the generator 4 and the power feed that undertaken by reactive power machine 6 momently.The phase place of voltage that for this reason, is produced by one or more generators 4 and the voltage that produced by reactive power machine 6 is mutually synchronization mutually.
Therefore; Before own energy supply to the conversion of external energy supply; Promptly before reactive power machine 6 is connected to network 2, the corresponding activation through Diesel engine 3 makes the phase place of Phase synchronization to the voltage that is produced by reactive power machine 6 of the voltage of boat-carrying network 2.Only after this is synchronous, just will reactive power machine 6 be connected to boat-carrying network 2 generator or all the other generators 4 will be broken off from boat-carrying network 2 via switch 14.
Alternatively, can also make the Phase synchronization of voltage of phase place and the boat-carrying network 2 of the voltage that produces by reactive power machine 6.If electric motor 7 is embodied as asynchronous machine, then this is especially easy, because the phase place of this type of machine constantly changes owing to slide, and in order to be connected to network 2, only needs to wait for the phase locked time.In other cases, for example, wherein drive idle machine, can be for example control by the closed-loop control of the phase place of the electric current that is fed to electric motor 7 or open loop and carry out synchronously by means of the transducer that connects from electric motor 7 upper reaches by synchronous machine.
From external energy supply to the conversion of own energy supply; For fear of voltage interruption; In a similar manner; Must make by the phase place of the voltage that is produced by the generator 4 of at first starting and boat-carrying network 2 or by the Phase synchronization of the voltage of the reactive power machine 6 of its supply, perhaps must make on the contrary reactive power machine 6 boat-carrying network 2 voltage phase place with by by the Phase synchronization of the voltage of generator 4 generations of at first starting.
For the own energy supply of ship 1, can also be by means of shaft coupling 9 once more with reactive power machine 6 from electric motor 7 de.
Shown in two kinds of situation under, reactive power machine 6 and electric motor 7 are intercoupled so that synchronously, yet wherein switch 14 is disconnected, and reactive power machine 6 is isolated from boat-carrying network 2.Have only in case electric when having taken place synchronously, just reactive power machine 6 is connected to boat-carrying network 2 and will makes generator subsequently or all the other generators 4 break off from boat-carrying network 2 via switch 14.
Yet, except synchronous, also might be that " machinery " is synchronous with respect to such " electric " of frequency and phase place.Be different to electric synchronously, with switch 14 closures so that mechanical synchronization is about to reactive power machine 6 and is connected to boat-carrying network 2 and mechanically makes reactive power machine 6 from electric motor 7 de by means of shaft coupling 9.In first step, will drive reactive power machine 6 with electric current then, and use electric current to come the driving electric engine with frequency f 2 from onshore network 12 with frequency f 1 from boat-carrying network 2, it starts independently of each other and operates.Operate reactive power machine 6 with the frequency and the phase place of boat-carrying network 2 then.Subsequently in second step, make mechanically mutually synchronization mutually of reactive power machine 6 and electric motor 7 through close switch shaft coupling 9.For this purpose, switch shaft coupling 9 is embodied as friction coupling, makes and set identical speed in each case with the friction on electric motor 7 sides in reactive power machine 6 sides.In order to reequip the external energy supply, this method means need be to the intervention of existing synchronizing sequence.
As from the substituting of 12 supplies of power network on the bank, can also be for example from the power station of floating, harbor power supply or offshore platforms supply external energy float.
The difference of described ship of Fig. 2 and ship shown in Figure 1 is to exist small-sizedly pilots engine 29, its be used to start reactive power machine 6 in case to ship 1 supply by the energy of directly presenting from network 2 via starting current transducer 30.In this case, reactive power machine 6 is coupled in an one of which axial end and pilots engine 29 and can be coupled to electric motor 7 in its another axial end.In this case, pilot engine 29 power of the power ratio of electric motor 7 is much bigger.
In the ship of in Fig. 3, describing 1, replace by electric motor 7 and to pilot engine 29.Therefore; Electric motor 7 is taken over and is used to start reactive power machine 6 with the function of piloting engine of carrying out the shaft generator operation (promptly when be that ship is when supplying its oneself energy), and also be useful on ship 1 the external energy supply outside provisioning engine function the two.Electric motor 7 can be connected to starting current transducer 30 or circuit 11 by means of switch 31 in this case alternatively.In this case, can alternatively shaft coupling 9 be embodied as the switch shaft coupling or the shaft coupling that is rigidly connected.
In the ship of in Fig. 4, describing 1, the generator 46 of the waste heat utilization system that its part only is shown 40 is used for the external energy supply, its used heat that will be used to drive the internal combustion engine of ship converts electric energy to.Waste heat utilization system 40 comprises the exhaust steam turbine 42 that is used to drive generator 46 and steam turbine 43, and it can be coupled to an end of the axle of generator 46 via shaft coupling 44.In addition, generator 46 can be coupled to electric motor 7 at the other end place of axle via shaft coupling 9 and transmission device 8.In order to be its own energy of ship 1 supply, generator 46 is coupled to exhaust steam turbine 42 and steam turbine 43, and comes mechanically to drive by the latter, still make it from electric motor 7 de.This means indirectly and it is driven by internal combustion engine as its energy source.
In order to supply external energy, generator 46 is separated with steam turbine 43 with exhaust steam turbine 42 and alternatively be coupled to electric motor 7 by means of shaft coupling 9 by means of shaft coupling 44.Electric motor 7 is connected to onshore network 12 and is used for since then the power of network via circuit 11 and operate.In this case, it drives generator 46, makes the latter produce and has the voltage U 1 of boat-carrying network 2 and the electric current of frequency f 1.
In the ship of in Fig. 5, describing 1, be used to supply external energy with the generator 56 of diesel generating set 50.Generator 56 can be coupled to Diesel engine 51 and can be coupled to electric motor 7 via shaft coupling 9 and transmission device 8 in its another axial end via shaft coupling 52 in an one of which axial end for this purpose.In order to be the energy of ship 1 supply its oneself.Generator 56 is coupled to the Diesel engine 51 as its energy source, and it is carried out Mechanical Driven, but make it from electric motor 7 de by the latter.In order to supply external energy, by means of shaft coupling 52 generator 56 is broken off from Diesel engine 51, and alternatively be coupled to engine 7 with shaft coupling 9.Electric motor 7 is connected to onshore network 12 and is used for since then the power of network via circuit 11 and operate.In this case, it drives generator 56, makes the latter produce and has the voltage U 1 of boat-carrying network 2 and the electric current of frequency f 1.
