Description

Oil electricity is from hybrid propulsion

Technical field

Background technology

Transportation is one of major fields of energy resource consumption and discharge, and boats and ships are as the maximum apparatus of transport of carrying capacity ratio in communications and transportation, and the quality of its energy-saving effect is very large on the impact of national economy.Energy-saving and emission-reduction have become the important topic of countries in the world shipbuilding circles and shipping community's research; the problems such as it is related to saving fuel resource and cost, reduce exhaust emission, the economic benefit of environmental protection and shipping transport; development low-carbon economy is also the important channel realizing the transformation of communications and transportation development pattern.

2011, Marine Environmental Protection Committee of International Maritime Organization (IMO) have passed international ocean shipping reduction of greenhouse gas discharge measure mandatory provision, determined new ship design energy efficiency index EEDI and boats and ships energy efficiency management plan SEEMP two boats and ships Energy Efficiency Standards.China's " inland river green ship specification " also comes into force, proposes clear and definite requirement to the energy efficiency indexes of inland water transport boats and ships, emission control and noise emission etc.

The subject matter that current inland water transport boats and ships exist:

1, navigation channel is complicated and changeable, main engine power redundancy

China's cruiseway waters is vast, silk floss is prolonged in course line, navigation channel is complicated, for adapting to the needs of the geographical environments such as different navigation channel current port and piers, the main engine power of usual inland water transport boats and ships has certain redundancy when designing, so that when bad working environments, can ensure the safety of propulsion of ship, this just makes main frame all not operate in its optimum condition at a large amount of work-hourses, i.e. the most energy-conservation and most effective point.

2, by drinking water restriction, propeller efficiency is lower

The branch line situation of many cruiseways is also in below 5 grades of navigation channels, the depth of water is more shallow, weedy under water, riverway sludge is piled up, even if river course is through canalization, but because river surface is narrow, boats and ships are when crossing or surmount, extremely near with bank, for avoiding the grazing of screw propeller and river levee, add the impact by drinking water restriction, the diameter of the screw propeller of usual inland navigation craft is all less, causes propulsion coefficient lower.

3, city or Scenic Spot Area are passed through in navigation channel, and environmental pollution is serious

River navigation and littoral resident living closely bound up, the discharge of diesel engine and noise, had a strong impact on the life of two sides resident, becomes the problem that environmental air pollution aspect is very important.

In view of the foregoing, current inland water transport boats and ships are badly in need of seeking various new forms of energy, new product, up-to-date technology, with the energy-conservation energy, emissions reduction, reduction noise for basic goal.Boats and ships hybrid propulsion system is one of current research direction.

(1) the external present Research about boats and ships hybrid propulsion system at present

Hybrid power boats and ships technology is still in the stage constantly explored and study at present.In the world, having many Research Centers to propose some correlation theories and method, and realize to some extent at submarine and yacht field---the submarine of first fuel cell and bavin one electric mixed dynamic system starts to shake down first in April, 2003 at Kiel, Germany port in the world.In January, 2010, Italy and Slovenia joint research and development GREENLINE 33 hybrid power yacht are first the yachts being mixed with battery pack, solar power and diesel powered.In recent years, ship design person started this concept to apply to merchant navy vessel, especially deep ocean work multipupose vessel.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model preferred embodiment is elaborated.

The utility model oil electricity is according to vessel motion operating mode and main unit load change from hybrid propulsion, a kind of novel hybrid Promoting Form that automatic switchover propulsion source drives.This device mainly comprises two major parts, and as shown in Figure 1, 2, a part is diesel propulsion part, is made up of diesel engine (band automatic speed regulation mechanism), reducing gearbox, axle system, differential marine cycloidal propelling device etc.; Another part is electric propulsion part, and be made up of bank electricity charging unit, auxiliary diesel generater set, electrokinetic cell, battery manager, actuator, dynamoelectric machine, frequency-variable controller etc., two parts are linked together by synchronous cog belt.

As shown in Figure 1, 2, power accumulator group 4 is electrically connected by power supervisor 3 and controller 1, controller 1 with drive platform 2 and electrically connect, controller 1 also connects two actuators 6 and a slow box 5 that powers on, the slow box 5 that powers on is serially connected with one end that two actuator 6(and controller 1 are connected) between, two actuators 6 respectively connect a synchronous dynamo 7, the output shaft of synchronous dynamo 7 installs a synchronous pulley 13, controller 1 also connects two diesel engine throttle motor servo drivers, 10, two diesel engine throttle motor servo drivers 10 and respectively connects a diesel engine throttle servomotor 9; Main diesel engine speed-change gear box 14, by installing another synchronous pulley 12, passes through synchronous cog belt 15 interlock between synchronous pulley 12 and synchronous pulley 13.Synchronous cog belt 15 and motor shaft, by synchronous pulley 13 interlock, pass through synchronous pulley 12 interlock with one end of main frame universal coupling 11.Main frame universal coupling 11 realizes synchronous axial system by synchronous cog belt 15 and the main shaft of motor 7.The other end of main frame universal coupling 11 and the power intake interlock of differential marine cycloidal propelling device 8.

Synchronizing jugged belt involved by the utility model and shafting of main engine part adopt prior art to realize, and parts buyable involved by this part, therefore will not describe in detail this part-structure, only introduce the course of action between synchronous cog belt and axle system below.

Divide different operating mode, main frame universal coupling 11 power can export from main diesel engine speed-change gear box 14, also can pass through belt-driving from permagnetic synchronous motor 7.Action relationships is as follows:

(1) gear case does not conform to row, and synchronous magnetoelectric machine is as motor output torque: actuator switches on power and presses enable switch, and motor output torque synchronously drives plunging joint to rotate by synchronous cog belt, and plunging joint rotating speed is consistent with electrical motor output speed.

(2) gear case closes row, and synchronous magnetoelectric machine dallies: actuator switches on power, but enable switch remains open state, and motor, owing to not being connected to actuator, now both not had moment of torsion to input, and do not had load to export yet, and plunging joint idle running now only followed by motor.

(3) gear case closes row, synchronous magnetoelectric machine is as motor output torque: actuator switches on power and presses enable switch, motor output torque synchronously drives plunging joint to rotate by synchronous cog belt, main diesel engine passes through gear case output torque to plunging joint simultaneously, now because electrical motor is in torque mode, rotating speed can follow plunging joint rotating speed automatically, so now plunging joint rotating speed is consistent with main diesel engine output speed, motor speed follows action.

(4) gear case does not conform to row, synchronous magnetoelectric machine uses as electrical generator: actuator switches on power and presses enable switch, at torque setting end input negative voltage, then driver drives motor exports negative torque, but the moment of torsion rotated forward that now main diesel engine provides also is added on motor, and this contrary outer force rate motor output torque is large, and at this moment motor is in generating state, now plunging joint rotating speed is consistent with main diesel engine output speed, and motor speed follows action.

The basic functional principle of the utility model system changes according to vessel motion load behavior, based on electric propulsion, the electric energy originally stored is exported by coaxial motor, when electric power is not enough or load becomes large, when electric propulsion can not meet shipping sail speed, diesel engine starting is grid-connected, combine together with electrical motor and propelling unit power is provided, if because electric power is not enough, then not only automatically after diesel engine starting, provide power to load, the electrical motor that original power advances simultaneously is also transformed into shaft generator work, to electrokinetic cell reverse charging energy storage, if because the sudden change of load makes diesel engine starting, when the load decreases, diesel engine is automatic logout again, when when heavier loads, electric power is not enough, diesel-engine generator can be used to power battery charging, ensure that boats and ships continue to realize hybrid power, to reach the object of economize energy emissions reduction.

Electric propulsion pattern: refer to that electrokinetic cell is through extraordinary variable frequency drives, make permanent magnetic servo synchronous dynamo be operated in electric motor mode, drives propelling unit, now diesel engine stop.Electric propulsion pattern is mainly used in ambient environment has higher requirement to discharge and noise, or boats and ships only need the operating mode compared with low thrust or diesel engine fault.The utility model conceptual design is the hybrid power system based on electric propulsion, first by automatic checkout equipment and control system, switch to motor operation mode, electrokinetic cell for boats and ships provide power (if when electrokinetic cell electric energy is not enough, also can diesel-engine generator auxiliary charging function is provided).Use two-way frequency-variable controller to control the rotating speed of electrical motor, can mate with propelling unit better, improve the handling of boats and ships.In addition, diesel powerplant also can be boats and ships accessory equipment and life load supplying.

Mechanically-propelled pattern: refer to that main diesel engine runs, drives propelling unit by reducing gearbox and axle system; Now main diesel engine provides power for boats and ships, and simultaneously by control system, axle translator is switched to generator operation mode, utilizes the redundant power of diesel engine to power battery charging, this is a kind of common power form.In the utility model system, mechanically-propelled pattern is mainly used in the operating mode of navigation medium power battery deficiency.

Hybrid power advances pattern: electrokinetic cell is by axle band electrical motor, main diesel engine by reducing gearbox, and both are axle drive shaft system and propelling unit simultaneously, for boats and ships provide maximum thrust.Hybrid mode is mainly used in heavy load operating mode, and diesel engine full power and Variable power now can be divided into export operating mode, and when load is enough large, electrokinetic cell and diesel engine all need full power to export; When load is greater than electrokinetic cell, but when exporting without the need to diesel engine full power, control (based on electric propulsion) by the management of the utility model system energy, automatically regulate diesel engine speed, reduce fuel charge, to reduce the power stage of diesel engine.

Inland navigation craft oil electricity is from hybrid propulsion system technical design:

3) research of the energy management strategy of oil electric mixed dynamic

Energy management strategy is the utility model hybrid power control system emphasis place, and it directly affects performance and the survivability of hybrid power boats and ships.Energy management strategies must under the prerequisite meeting certain boundary conditions constraint, utilize rational method Sum fanction to distribute the optimization that the different energy sources in hybrid power carries out making time and size, thus obtain the inaccessiable optimal control target of traditional power.This operating strategy is with energy-saving and emission-reduction noise reduction for target, and preferential according to electric propulsion, according to the restriction of the change of electrokinetic cell capacity, loading demand and navigation total time during ship's navigation, the technology path of main diesel engine Automatic Variable Power hybrid propulsion is researched and developed.

The utility model system specifically can be divided into following three kinds of mode of operations five kinds of operating modes to carry out energy management control.

1) electric propulsion pattern: load stabilization and less, electrokinetic cell in night by bank electricity full charge; The speed of a ship or plane that now electrokinetic cell is selected according to boats and ships discharges, and diesel engine does not work.

2) diesel propulsion pattern:

1. electrokinetic cell energy shortage, but load is less, allows diesel engine to be charged to power battery pack by shaft generator while driving propelling unit.Now by measuring battery tension, capacity and tailing axle moment of torsion, diesel engine can be realized and automatically start, and by control system, electrical motor being switched to shaft generator mode of operation, charging to power accumulator.

2. electrokinetic cell energy shortage, load larger diesel engine power during navigation, diesel engine, as promoting mainly work, does not have redundant power to power battery charging.Now according to real ship needs, auxiliary diesel electrical generator can be started and charges to power accumulator.

3) hybrid power advances pattern:

This pattern is that motor is controlled automatically by PLC, and enters the operating mode automatic decision handler of PLC, and the throttle size of diesel engine is by handle Non-follow control, and this pattern is mainly used in debugging or abnormal condition.Concrete operations: by K switch 2 dozens at hybrid power shelves, simultaneously by K switch 1 dozen at manual gear, I0.7, I1.0 mouth receives 24V voltage signal respectively, read after signal through PLC, Q0.0 no-voltage signal exports, relay 1J1 dead electricity, and corresponding contacts 1J1 is failure to actuate, diesel engine connects handle control signal, and throttle is controlled by handle; Q0.4 no-voltage signal exports, and relay 1J5 must not be electric, and corresponding contacts 1J5 is failure to actuate, and handle signal is disconnected, and PLC analog output mouth V signal connected by motor, and motor is in auto state.Remaining operation is performed by PLC operating mode automatic decision handler.

4, two angle of rake stationary problems:

1) native system left and right propelling unit is controlled by two handles respectively, when two propelling units need synchronous, is mechanically connected by two handles.When two propelling units do not need synchronous, as special action such as needs translation, casts, then cancel the mechanical connection of two handles, left and right handle can be operated separately.

2) under hybrid mode, after entering operating mode automatic decision handler, the moment compares left and right propelling unit rotating speed, if both speeds discrepancy exceed certain numerical value, then and the angle of rake throttle that self-regulating rotary speed is larger, synchronous to ensure.

5, system alarm and protection:

1) low voltage is reported to the police: when battery tension is lower than low alarm limit u1, and Q1.1 exports 24V voltage, connects indicator lamp L4 and buzzer phone FM simultaneously, sends sound and light alarm, manual intervention process.

2) left/right Motor Over Speed is reported to the police: when left and right motor speed exceedes upper limit rotating speed, and overspeed alarming input port I1.2, I1.3 report to the police and input 24V voltage, PLC Received signal strength, connect indicator lamp L2 and buzzer phone FM, send sound and light alarm.PLC sends the enable cut-off signal of motor simultaneously, and disconnect motor enable, motor quits work, and actuator sends motor fault warning signal.

Six, automated system operation situation

Operating mode one:

This work condition state: accumulator capacity is sufficient, complete electric propulsion.

Only under hybrid mode, just can carry out switching between operating mode, switch between operating mode and automatically carried out by PLC.After ship leaves the port, motor is adjusted to automatically, and diesel engine is also automatic.Motor is 100% moment of torsion work now.Under the prerequisite of capacity of cell Q1>55%C, left/right propelling unit actual speed V is compared with the rotating speed n1 of setting, as propelling unit rotating speed is more than or equal to the rotating speed n1 of setting, then at operating mode one periodical duty.

Jump out the situation of operating mode one:

1) capacity of cell Q1 < 55%C, enters operating mode four;

2) propelling unit rotating speed is less than the rotating speed n1 of setting, enters operating mode two.

Operating mode two:

At capacity of cell Q1>55%C, condition under, PLC enters operating mode two after detecting that propelling unit rotating speed is less than the rotating speed n1 of setting.First send diesel engine starting signal: send out throttle commands by P0 mouth, after certain time-delay T1, wait for that diesel engine is stablized.Prepare for gear case closes row, left/right propelling unit actual speed compared with diesel engine rotating speed n2 now:

1) if propelling unit rotating speed is greater than diesel engine speed n2, then Motor torque output valve (from analog output V mouth) is reduced, propelling unit rotating speed is reduced by ship resistance, circulate this operation until left/right diesel engine speed all with propelling unit rotational speed matches, now by PLC, Q0.2 mouth is exported 24V, relay 1J3 obtains electric, the 1J3 closing of contact, and gear case closes row.

2) if propelling unit rotating speed is less than diesel engine speed n2, then allowing Q0.1 export by PLC is 0, and relay 1J2 must not be electric, and 1J2 is failure to actuate contact, and motor Enable Pin disconnects, and motor dallies.Moment after motor idle running, PLC sends conjunction row signal, and Q0.2 mouth is exported 24V, and relay 1J3 obtains electric, the action of 1J2 contact, and gear case closes row.After this operation, allow Q0.1 export by PLC and obtain electric 1J2 contact action for 24V, relay 1J2, motor Enable Pin closes, and PLC controls motor and works under nominal torque.

After conjunction row terminates, propelling unit works under motor and diesel engine drive jointly, and the rotating speed now set becomes n3, now angle of rake actual speed is compared with rotating speed n3, ensures that propelling unit rotating speed maintains n3 by regulating throttle size.Wherein being embodied as of throttle size adjustment: by PLC position control module to control the motion of throttle motor, controls to realize motor position, thus realizes throttle size adjustment.Wherein the size of throttle is drawn by pid algorithm.

Jump out the situation of operating mode two:

1), after pid algorithm calculates, the accelerator open degree that P0 mouth exports is 0, and continues for some time T2, then illustrate and now do not need diesel engine additional thrust.Allowing Q0.2 export by PLC is 0, relay 1J3 dead electricity, and switch 1J3 opens, and diesel engine departs from, and then programming jump returns operating mode one, and the comparison tachometer value of setting gets back to n1.

2) capacity of cell Q1<55%C

3) when propelling unit rotating speed drops to lower bound speed n4.

Operating mode three:

Namely the accelerator open degree that in operating mode two, PID exports is 100%, and throttle reaches maximum situation.

Jump out the situation of operating mode three:

1) accelerator open degree that PID also exports is 100%, and after continuing for some time T3, the impeller speed measured is lower than alarm velocity, illustrate that propelling unit may be wound and run into exception, now system alarm, stops diesel engine work, allows accelerator open degree equal 0, namely throttle is closed, simultaneously disable motor Enable Pin.

2) capacity of cell Q1<55%C

Operating mode four:

This work condition state: capacity of cell Q1<55%C, under the prerequisite ensureing charging current, diesel engine can export different power according to load variations and keep ship's navigation.

After capacity of cell Q1<55%C, enter operating mode four program part.Now export 24V by PLC control Q0.3 mouth, relay 1J4 obtains electric, 1J4 open contact closes, connect actuator negative torque signal port, and given torque, control motor and be in charge condition, now diesel engine power is divided into charging and advances two parts, so the rotating speed of setting becomes n5, now angle of rake actual speed is compared with the rotating speed n5 of setting, by regulating throttle size (control method as above), to ensure that propelling unit rotating speed maintains n5, wherein the size of throttle is drawn by pid algorithm.

Jump out the situation of operating mode four:

1) accelerator open degree that PID exports is 100%, and after continuing for some time T4, the impeller speed measured is less than lower limit speed n6, illustrate that load is larger, propelling unit needs to stop charging, now disconnect motor Enable Pin (operation as above), allowing diesel engine power completely for advancing, namely entering operating mode five.

2) capacity of cell Q1 > 90%C

Operating mode five:

Under the condition of situation (1), jump out operating mode four and enter operating mode five, now diesel engine horsepower output 100% is for advancing, and accelerator open degree value is set to 100%.

Jump out the situation of operating mode five:

Record propelling unit rotating speed and be greater than n5, and maintain a period of time T5, illustrate that diesel engine has power more than needed to charge, now motor Enable Pin connected, system gets back to operating mode four.
