Description
Technical field
The present invention relates to a kind of hybrid power system, specifically a kind of hybrid power system that uses clean fuel.
Background technology
Pure battery-driven electronlmobil, the cost height of storage battery, the life-span is shorter, and the mutual transition loss of electric energy and chemical power is huge in charge and discharge process, thereby uses very uneconomical.At present actual use be mostly the mixed power electric car that matches with engine petrol, its structure is to connect engine petrol, power accumulator and electrical motor respectively by control unit, to drive load.This wherein, the driving electric that existing storage battery provides, also useful engine petrol is as additional power or as the main power that drives.Two kinds of dynamic mixing work have fully adapted to the various operating modes of automotive operation.But higher because of petrolic use cost, and tractive performance is not as good as diesel motor, so what then generally adopt on large-scale and heavy-duty vehicle is diesel motor.Diesel motor has the fuel-efficient and big characteristics of exerting oneself of operation, particularly can export low-speed big, is large-scale and the first-selection of heavy motor vehicle assurance vehicle performance.But diesel motor exists NO
xDischarging and pollution problem such as over-emitting black exhaust discharging are difficult to reach the effluent standard of Europe III.If in engine petrol or diesel motor, directly use clean fuel, as compression natural gas (CNG), liquefied natural gas (LNG), autogas (LPG), ethanol or biodiesel etc., the capital produces a very large impact the low speed operating mode of engine petrol and diesel motor, its low speed output torque 15-20% that can descend.In addition, when working under the low speed operating mode, the fuels and energy conversion efficiency of driving engine is very low, promptly in order to reach the low-speed torque characteristic of original engine petrol or diesel motor, needs the more clean fuel of consumption rate gasoline or diesel oil.This has caused the waste of fuel and the raising of cost on the contrary.In order to obtain or high pulling torque output when guaranteeing low speed, just can only strengthen the power grade of driving engine, but the so further consumption of increasing fuel, the also corresponding increase of its machine cost is a lot, and the result is also very uneconomical.
Summary of the invention
Purpose of the present invention just provides a kind of hybrid power system that uses clean fuel, to overcome the deficiency that prior art exists, is satisfying the takeoff output requirement and is reaching on the basis of effluent standard, improves the performance driving economy of hybrid electric drive system.
The object of the present invention is achieved like this: the hybrid power system that uses clean fuel is to drive load by control unit tap driving engine and electrical motor, on control unit, be connected to energy storage unit and electric power input/output interface, driving engine is selected for use especially to using the special engine of clean fuel, electrical motor is then selected for use to having the rare-earth permanent magnet motor of low-speed big output characteristic, the use that combines of driving engine and electrical motor.Specifically, using the special engine of clean fuel can be the special use or the general purpose engine of burning compression natural gas, liquefied natural gas, autogas, ethanol or biodiesel etc.; Rare-earth permanent magnet motor can be rare-earth permanent-magnet synchronous motor or rare earth permanent magnetic brushless dc motor.
The present invention will use engine petrol or the diesel motor in the alternative original hybrid power system of the special engine of clean fuel, with the common motor in the alternative original hybrid power system of the rare-earth permanent magnet motor with low-speed big output characteristic, and designed corresponding power drive system.This power drive system is to be the power drive system of hybrid power system with rare earth permanent magnetic brushless dc motor and driving control system thereof.When vehicle operation during at the low-speed big mode of operation, this power drive system can be exported high pulling torque in the control motor under low speed state, and can provide electric power for it by energy storage unit such as storage battery, electric capacity, thereby need not provide the output of the high pulling torque under the lower-speed state as system by the special engine that uses clean fuel.Like this, even system need provide electric energy or moment of torsion output by the special engine that uses clean fuel, also can allow the special engine that uses clean fuel be operated in and have under higher efficient and the high rotational speed condition.Guaranteed that thus vehicle can have the takeoff output of high pulling torque when the low speed operating mode.
The special engine of the use clean fuel among the present invention can be the separate unit setting, also can be many in parallel uses.The special engine of the use clean fuel of many parallel connections can be the special engine of burning with a kind of clean fuel, also can be the not special engine of clean fuel of the same race that burns.Use multiple clean fuel co-operation, can satisfy the job requirement of hybrid power system well, thereby make hybrid power system of the present invention can accomplish not rely on fully traditional non-renewable resources such as gasoline or diesel oil the clean fuel driving engine.
The present invention helps to realize the popularization and the utilization of clean fuel and driving engine thereof, reduce the discharge amount of exhaust gas of driving engine, reduce the environmental pollution that causes thus, reduce the consumption of gasoline or diesel oil, improve the performance driving economy and the outputting power characteristic of hybrid power system, and make power grade extension, the systematization of hybrid power system, adapt to and satisfy large-scale and heavy motor vehicle demand hybrid electric drive system.
When running into bringing onto load that the special engine that uses clean fuel usually occurs and start difficult situation, the present invention is owing to used above-mentioned power drive system, and the low-speed big in the time of therefore can satisfying vehicle launch basically requires the requirement with speed governing.Even the moment of torsion deficiency that power drive system provides uses the special engine of clean fuel also only to provide less complementary moment of torsion output, because power drive system has been born most moments of torsion.If special engine also has load of electrical generation, the rotating speed of the working speed of driving engine during also than vehicle launch can exceed a lot, so the problem that the situation that consumes clean fuel excessively that prior art exists in using and the exhaust emission that may occur exceed standard can not occur.In addition, because the low-temperature startup performance of clean fuels such as natural fuels is all better than gasoline and diesel oil, so can not occur starting difficult in addition take place " flooding mouthpiece " (promptly not atomizing or too much oil spout flooded light-up plug, make it to form jumper spark) phenomenon.Simultaneously in the road up train of blocking up or when crossing red light idling waits, use the present invention can be so that use the special engine of clean fuel to work less or work hardly, or concentrate on the high efficiency state and generate electricity, be storage battery or super capacitor stored electric energy, this just makes the consumption of fuel and the pollution of blowdown want much less.

Fig. 2 is the structured flowchart of the hybrid power system of parallel use clean fuel.
The specific embodiment
Embodiment 1:
The hybrid power system of tandem use clean fuel of the present invention as shown in Figure 1, this system includes special engine 1, control unit 3 (control center) that uses clean fuel and the rare-earth permanent magnet motor 4 with low-speed big output characteristic, is connected to energy storage unit 6 and electric power input/output interface 7 on control unit 3.Energy storage unit 6 generally is made up of storage battery and super capacitor etc.This system also includes electrical generator 2a.Use the special engine 1 of clean fuel to be connected with electrical generator 2a, constitute clean fuel generator set 10 by mechanical drive mode.This generator set 10 can be that single cover or many covers are in parallel, and its power output end connects control unit 3, and the power output end of control unit 3 and rare-earth permanent magnet motor 4 join, and the takeoff output of rare-earth permanent magnet motor 4 connects wheel or other mechanical loads 5 of vehicle.
Its mode of operation is: the electric power energy of clean fuel generator set 10 outputs, transfer to control unit 3, control unit 3 provides electric energy for rare-earth permanent magnet motor 4, exports wheel or other mechanical loads 5 to by rare-earth permanent magnet motor 4, and required rotating speed and moment of torsion is provided.Control unit 3 is controlled and is managed the energy of total system simultaneously.When the required electric energy of rare-earth permanent magnet motor 4 more after a little while, control unit 3 control clean fuel generator seies 10 do not generate electricity (provided rare-earth permanent magnet motor 4 this moment by energy storage unit 6 work energy) or few generating perhaps provide electric energy to energy storage unit 6.Directly electric energy is exported in the outside when the needs hybrid power system, when perhaps needing the outside for native system power supply or charging, control unit 3 will be realized the output or the input of electric power by electric power input/output interface 7.When energy back appearred in wheel or other mechanical loads 5, rare-earth permanent magnet motor 4 will change generating state over to, and the electric energy of feedback can enter energy storage unit 6 by control unit 3.
After adopting the alternative hybrid power system of the special engine that uses clean fuel with gasoline or diesel motor work, little and the little characteristics of output torque of horsepower output preferably are equipped with a kind of " can adapt to the electrical generator of velocity variations on a large scale " that the applicant formerly applies for a patent (CN021089458) for the electrical generator 2a in the native system during at the special engine low speed that uses clean fuel.This electrical generator both can keep the basicly stable of output services voltage under the bigger situation of rotation speed change scope, also the operating voltage of exportable appointment also can dynamically improve or reduce output voltage by demand at any time by the control to engine controller.Like this, when driving this electrical generator work with the special engine 1 that uses clean fuel, the rotation speed change of driving engine just can only influence the horsepower output of electrical generator.By regulating the rotating speed height of the special engine 1 that uses clean fuel, the electromotive power output of the bonded assembly electrical generator 2a of institute also changes thereupon.When this hybrid power system needs high-power output, use the special engine 1 of clean fuel just to be operated under the higher rotation speed; Otherwise, just be operated in than under the slow speed of revolution.So just can carry out actv. to the horsepower output of clean fuel generator set 10 and regulate, thereby guarantee to use the special engine 1 of clean fuel to be operated in rotating speed and all adjustable mode of operation of horsepower output.Thus can be under the prerequisite of the horsepower output of meet requirements, allow the special engine 1 that uses clean fuel be operated in the minimum and working speed of the consumption of fuel low mode of operation of trying one's best, even thereby make the special engine 1 of use clean fuel be operated under the lower state of rotating speed, the output requirement of high pulling torque also can not appear.When system needs high-power or during high pulling torque output, the horsepower output of clean fuel generator set 10 will increase, thereby makes the engine operation rotating speed rise, and can ensure the requirement of 10 pairs of power of clean fuel generator set and moment of torsion in high rotating speed district.And at this moment, use the special engine 1 of clean fuel just can enter into mode of operation preferably.Otherwise driving engine will be operated in low regime.So both reduce consumption of fuel, also reduced the loss of driving engine itself.
Rare-earth permanent magnet motor 4 in the present embodiment should be selected rare-earth permanent-magnet synchronous motor for use, especially is best with the rare earth permanent magnetic brushless dc motor.Because rare earth permanent magnetic brushless dc motor can fully guarantee the high pulling torque output under the low speed operating mode, and its stall operating characteristic and speed regulation characteristics excellence, high efficiency is fit to frequent startup and parking, and the cal val when startup or long-time slow running is few.When series connection type hybrid power system of the present invention needs low-speed big output, the power drive system of being formed by rare earth permanent magnetic brushless dc motor 4 and control unit 3, the clean fuel generator set 10 of the special engine 1 required drive of using clean fuel only there is requirement on the power, and does not have the requirement of moment of torsion aspect.When hybrid power system need be exported low-speed big, rare earth permanent magnetic brushless dc motor 4 desired power were less, and less energy consumption is lower naturally to the power requirement of clean fuel generator set 10.So if do not consider the power supply of energy storage unit 6 in the electric system, using the special engine 1 of clean fuel is being to be under the low speed small power state to work under this kind operating mode, its output torque is little, the operating characteristic requirement of suitable driving engine.Otherwise, need be when the high speed high pulling torque be exported when series connection type hybrid power system of the present invention, power drive system is operated under the bigger power demand state.And the operating mode of this moment meets in the rational advantage operation interval of the special engine 1 that uses clean fuel.This is the design application of power drive system in this series connection type hybrid power system among the present invention.These have all satisfied the job requirement of using the hybrid power system of clean fuel fully.
This series connection type hybrid power system is applicable to the vehicle of frequent start-stop in the city, as taxicar, bus etc.Wherein be to operate to the master, use the special engine 1 of clean fuel to provide the driving energy as rare-earth permanent magnet motor 4 with the rare-earth permanent magnet motor powered vehicle.When stopping, slow down or sliding, use the special engine 1 of clean fuel also can replenish electric power for the energy storage unit of forming by storage battery or super capacitor 6.In a word, this system provides comparatively stable working environment for the special engine 1 that uses clean fuel, the slam open that the power system of having eliminated simple use clean fuel may occur when work is in the hope of improving the drawback of horsepower output, so this hybrid power system consumption of fuel minimum, degree of utilization is the highest.
Employed power drive system in this hybrid power system also has bigger difference with the power drive system that uses gasoline or diesel hybrid system.Use gasoline or diesel oil to be the driving engine in the hybrid power system of fuel, its low speed torque good output, so can be simultaneously and the line output low-speed big with power drive system, the drive motor that is adopted can be AC induction motor or rare earth permanent magnet class motor.And hybrid power system of the present invention then mainly is with power drive system output low-speed big, uses the special engine 1 of clean fuel then not have moment of torsion output, perhaps only is the work of auxiliary electrical drive system.Promptly when this hybrid power system will move under the low-speed big state, the special engine 1 that uses clean fuel is to ensure the electromotive power output of electrical generator 2a basically, power drive system then is according to the output requirement, with using the special engine 1 of clean fuel to drive the electric power that electrical generator 2a sent and offered power drive system, offer rare-earth permanent magnet motor 4 and driving control system thereof.The horsepower output that makes clean fuel generator set 10 in this hybrid power system become thus can to make generator set and all adjustable energy-efficient system of output speed of rare-earth permanent magnet motor.Because the low-speed big characteristic and the high-speed high-power characteristic of rare-earth permanent magnet motor 4 can be taken into account simultaneously, thereby have satisfied the requirements at the higher level of hybrid power system of the present invention to power drive system well.
An important application of present embodiment is the non-mains supply operation of city trolley bus or city railway vehicle.Prior art is to have adopted power supplies such as storage battery, can't solve and realize the operation of longer distance, adopt the present invention then can make the vehicle of this class powered operation, can realize the disengaging operation of power networks of any section theoretically, be not subjected to the weight of storage battery and the restriction of capacity, it is a lot of that operating cost is descended.
