Description
Technical field
The present invention relates to be applied to the clean energy resource system of log cabin, particularly utilize the SOFC cogeneration system, electric power and the hot water service that meets the clean energy resource requirement is provided for log cabin.
Background technology
As everyone knows; The clean energy resource definition can use " environmental protection, energy-conservation, low-carbon (LC), efficient " eight words to summarize; And for log cabin; The clean energy resource system not only is meant energy supply side, also comprises energy user, and the equipment of its configuration and equipment operation mode all will reach clean energy resource definition requirement.
Talk from energy supply side earlier, the construction form of log cabin is that assemble flexibly at prefabrication, scene, and mobility is strong; In addition, lower to building the region requirement, forest, desert, mountain region, beach and suburb, city all are that log cabin can be built the place, and adaptability is strong, is adapted at tourist district and uses, and can not cause big destruction to environment.Therefore, log cabin rises as a kind of novel travel in holiday inhabitation form just gradually, and each destination, big tourist hot spot is developed travel in holiday one after another and used log cabin, makes it to become the new favorite of tourism real estate.
But many travel in holidays scenic spot more particularly is located in the scenic spot on high mountain, forest, island, often has inconvenient traffic, and the urban construction shortcoming may not have perfect supply of electric power; Or ski winter, the seasonal holiday resort of swimming in summer, and electric load is extremely irregular.In these cases, will provide the diesel generating set generating for oneself.Obviously, this supply power mode not only uneconomical (generating efficiency is low) but also not environmental protection (exhaust emission is big), the big large disturbance tourist environment peace and quiet degree of the noise that especially generates electricity meeting is not for people tolerate.
Certainly, can select wind power generation, this type of environment-protecting clean energy power supply of photovoltaic generation now.But also have following defective: the one, to all specific (special) requirements of erecting bed, wind resource to be arranged such as wind power generation, photovoltaic generation needs illumination condition, and this not any tourist attraction all possesses; The 2nd, no matter wind power generation or photovoltaic generation all are intermittent power generation energy resources, can not guarantee to supply power continuously whenever and wherever possible; The 3rd, if accomplish continuous power supply, must increase the capacity and the energy-storage battery device of wind-powered electricity generation or photovoltaic generation unit, this has just increased equipment cost greatly.
In addition, except electricity available (see TV with turn on the aircondition etc.) will be arranged, hot water service (having a bath and heating installation) also was absolutely necessary travel in holiday with log cabin.That is to say; In the environment that does not have municipal administration power supply, air feed; Log cabin will solve electric power and hot water service problem simultaneously, and main dependence provided TRT for oneself, but will accomplish by clean energy resource definition requirement; But also will be as much as possible with lower operation cost, several kinds of modes mentioned above all defectiveness are not accomplished not even easily.
Take another look at energy user: it is main that the energy of log cabin uses with household electrical appliance, like lighting, television set, refrigerator, washing machine, microwave oven, electromagnetic stove; The water heater that is used to have a bath; Be used for air conditioner that the log cabin indoor temperature regulates, electric heater etc.Above household appliances all are commercially availabie, can only select to meet the household appliances of national energy-conservation efficiency sign at present.To further reach energy-conservation and efficiently utilize the energy, also need household appliances enterprise that "smart" products are provided.
Summary of the invention
The objective of the invention is to deficiency, utilize a kind of SOFC cogeneration system, under the control of energy conservation control computer, electric power and the hot water service that meets the clean energy resource requirement is provided for log cabin to above-mentioned prior art.
The tradition thermo-mechanical power generation all is one and becomes heat energy from chemical energy that heat energy is converted into the process that mechanical energy becomes electric energy again.Such as thermal power generation, be exactly that coal produces steam through burning, the steam driven steam turbine drives generator for electricity generation again.
Fuel cell power generation then is the process that is converted into electric energy by chemical energy.Fuel cell is the TRT that the chemical energy of fuel gas (like natural gas, hydrogen, coal gas etc.) and the generation of airborne oxygen reaction is converted to electric energy through electrochemical reaction.
Consider log cabin that travel in holiday is used will supply power simultaneously power and heat supply water, so the present invention selects SOFC (SOFC) for use.Said SOFC is formed (similar " sandwich " structure) by anode, solid oxide electrolyte, negative electrode; Its operation principle is as shown in Figure 1; Continue to feed fuel gas from anode one side of fuel cell; Like natural gas (mainly being methane), town gas etc., have the anode surface adsorbed fuel gas of catalytic action, and be diffused into anode and electrolytical interface through the loose structure of anode.Continue aerating oxygen or air in negative electrode one side, have the cathode surface adsorb oxygen of loose structure, because the catalytic action of negative electrode itself, make O
2Obtain electronics and become O
2-, under the effect of chemical potential, O
2-Got into the solid oxygen ion conductor of electrolyte effect, because concentration gradient causes diffusion, finally arrived the interface of solid electrolyte and anode, reacted with fuel gas, the electronics that loses is got back to negative electrode through external circuit (through overload, like bulb).
Meanwhile, when battery sent electric energy, the heat that electrochemical reaction produces was with the unreacted gas heated of negative electrode and anode completely.Anode end reaction fuel gas and negative electrode surplus air completely feeds thermal energy converter and burns; The high-temperature gas that burning produces is except being used for pre-heating fuel gas and the air; Can also through waste-heat recovery device hot water is provided or be used for the heating, thereby further be used.Like this, just reached the cogeneration purpose.
The SOFC generation technology is the technology that chemical energy in the fuel is directly converted into electric energy; Have that fuel tolerance is wide, the high and low cost of energy conversion efficiency, all solid state, modularization assembling, zero pollute advantages such as low emission, noiseless, can directly use multiple carbon based gas fuel such as carbon monoxide, natural gas, liquefied gas, coal gas and biogas.High-quality waste heat especially is provided, realizes cogeneration of heat and power, fuel availability is high, and all-round utilance is up to about 80%.
Obviously; In log cabin; Especially under the necessary municipal energy supply condition of the local shortage of travel in holiday; With the SOFC cogeneration system substitute routine provide for oneself diesel engine unit generating (use diesel generation, the difficult generating waste-heat that utilizes, heat supply also need be disposed electric heater or oil fired boiler.), can be with high efficiency, low cost, but environmental protection again, energy-conservation, low noise is supplied power and heat supply continuously, is very suitable.
Equally, if select wind-powered electricity generation or photovoltaic power supply for use, though also can accomplish to supply power with the clean energy resource mode, but still to dispose electric heater or the heat supply of solar water heater ability.Main is because wind-powered electricity generation or photovoltaic all belong to intermittent power generation energy resource, accomplish the heat supply of supplying power continuously, certainly will will increase installation costs such as energy-storage battery greatly.
For utilizing above-mentioned SOFC cogeneration system to realize the clean energy resource supply of log cabin, the present invention has adopted following technical scheme:
A kind of clean energy resource system that is used for log cabin comprises fuel cell cogeneration system and energy conservation control computer system, and wherein: said fuel cell cogeneration system utilizes gaseous fuel generating and heat production, offers log cabin electrical equipment and hot water facility; Said energy conservation control computer system is carried out control and management under the day-to-day operation and the state of emergency to fuel cell cogeneration system and log cabin electrical equipment, hot water facility; Adjust the power output (exerting oneself of generating and heat supply) of fuel cell cogeneration system by the actual load of log cabin electrical equipment and hot water facility; Let generating and electricity consumption reach or, thereby realize the clean energy resource supply of efficient, energy-conservation and environmental protection, low-carbon (LC) near dynamic equilibrium.
Lack under the pipe gas supply condition in that log cabin is local, said clean energy resource system also comprises fuel air supply system (being called for short CNG), outputs to the fuel cell cogeneration system after gaseous fuel (like the bottled natural gas) decompression of this fuel air supply system with compression.
Said fuel cell cogeneration system only need provide carbon based gas fuel, empty G&Ws such as natural gas, will produce and output AC civil power and hot water, and supply log cabin user uses.General; The fuel cell cogeneration system comprises solid-oxide fuel cell stack, devulcanizer, fuel reformer, air cleaner, blower fan, thermal energy converter and fuel cell system controller; Gaseous fuel is introduced into the devulcanizer desulfurization, handles the anode tap that gets into solid-oxide fuel cell stack through fuel reformer then; Air is delivered to the cathode terminal of solid-oxide fuel cell stack by blower fan after the air cleaner dedusting; Electrochemical reaction takes place and produces direct current in gaseous fuel and airborne oxygen in battery pile; This direct current converts electric main into and outputs to external circuit under the control of fuel cell system controller, supply the electrical equipment in the external circuit to use; The superfluous air of remaining gaseous fuel of anode tap and cathode terminal burns in thermal energy converter, the cold water that heating is injected.Like this; Under log cabin local shortage electric main and pipe gas supply condition, the fuel cell cogeneration system utilizes steel bottle filled with compressed natural gas and fuel air supply system thereof, connects water pipe; Can produce electric main and hot water, for log cabin independently provides electricity consumption and heat supply service.Because the operation of fuel cells principle has determined that adjustment fuel cell power generation power output is fairly simple, what are just passable mainly to adjust the gaseous fuel input, but also not too influence generating efficiency.
Described log cabin energy conservation control computer system; Gather the energy supply equipment of log cabin and the operating condition data that the energy uses equipment; Use the operating state of equipment to carry out program control (mainly being the power generation and heat supply power output of control fuel cell cogeneration system) according to pre-set programs to the energy supply equipment and the energy; Wherein said energy supply equipment comprises fuel cell cogeneration system and fuel air supply system, and said energy use equipment comprises log cabin electrical equipment and hot water facility.
The operational mode of log cabin energy conservation control computer system can comprise " conventional operation pattern ", " energy conservation model " and " emergency operating pattern ".Under set " conventional operation pattern " state; Mainly be that electricity consumption by different period log cabins is with the different rule of heat; Designed load variations program at times; Adjust the power output of fuel cell cogeneration system, thereby, reach the efficient power generation heat supply purpose of fuel cell through the big or small program control of exerting oneself.Under set " energy conservation model " state; Be on the procedure basis of load variations at times in the conventional operation pattern; Through gathering the load variations data of log cabin electrical equipment and hot water facility; The size of exerting oneself of FEEDBACK CONTROL fuel cell cogeneration system further improves generating and exports the positive correlation interlock that changes with thermoelectric load variations." emergency operating pattern " is when receiving relevant device work condition abnormality or equipment data in the hole; The risk control rank that energy conservation control computer is just pressed emergent shutdown procedure; Respectively fuel cell cogeneration system and/or fuel air supply system are carried out the emergency processing operation, as shutting down.
Further; Said energy conservation control computer system has log cabin equipment and User Recognition plug-in unit, mobile data communication interface and satellite navigation report communication interface; The energy conservation control computer system and the log cabin owner or administrative center are set up to be got in touch based on the telecommunication and the control of mobile communications network or satellite navigation system; To guarantee the independent power generation and heat supply facility long-term safety operation of log cabin; When chance failure or emergency situation appear in log cabin and equipment thereof, in time obtain the support and the relief of the log cabin owner or administrative center.
The preferred Beidou satellite navigation report of said log cabin energy conservation control computer system satellite navigation report communication interface communication interface; Beidou satellite navigation report communication mode can overcome in the log cabin location not to be had under the mobile communication service area situation, accomplishes that high reliable communication and control gets in touch.
The realization of technical scheme of the present invention at first needs the SOFC cogeneration system that can satisfy log cabin architectural power supply heat supply desired volume, is generally about 1 kilowatt to 10 kilowatts, perhaps brings up to tens kw of power magnitudes according to demand.The operation principle of this system (referring to Fig. 2) is: bottled natural gas is introduced into the built-in devulcanizer desulfurization of system; Again through fuel reformer carry out gas reformation handle (its objective is to selexol process with remove relative substance; The anode carbon distribution and the catalysis that prevent fuel cell stack are poisoned; To ensure the battery pile operate as normal), deliver to the anode tap of fuel cell stack afterwards; Air is delivered to the cathode terminal of fuel cell stack by blower fan after the air cleaner dedusting; Like this, battery pile just is converted into electric energy to most of fuel through electrochemical reaction; Air catalytic combustion in thermal energy converter that remaining gas fuel of anode-side and cathode side are superfluous, the cold water that heating is injected by water pipe.In addition, control automatically through system controller, the direct current that produces battery pile converts electric main to through inverter, can supply to use like electrical equipment such as television set, refrigerator, electric stoves in the log cabin; The catalytic combustion operating mode of control thermal energy converter, the hot water of output preference temperature supply to have a bath or the usefulness of other washings.
The realization of technical scheme of the present invention needs configuration air, water and fuel source.The configuration of its air and water (water tank of enough capacity of configuration) is fairly simple, and the configuration of fuel source only is discussed here.From the SOFC operation principle, can use multiple carbon based gas fuel, comprise natural gas, coal bed gas, town gas, and oil liquefied gas, biogas even methyl alcohol, dimethyl ether etc.But from log cabin market orientation of living in and use value, relatively real more available at present and scheme technology maturation is compressed natural gas (CNG) air supply system that is widely used in now in natural gas bus, the taxi.A compressed natural gas (CNG) fuel air supply system generally includes natural gas cylinder, decompression voltage regulator, all kinds of valves and fittings and computer controller etc.Its operation principle is the compressed natural gas of gas-fueled vehicles (CNG) fuel system of automobile roughly the same: as shown in Figure 3; Pressure regulation (decompression) effect through the decompression voltage regulator; Compressed natural gas gas in the natural gas steel cylinder is reduced to atmospheric pressure state from high pressure (generally about 20MPa); Control by a series of function control valves such as gas passage switching and flow size adjustment that comprise again, output to fuel-cell device.The all pressure of natural gas, the adjusting of flow are to be controlled by the combustion gas computer.
The realization of technical scheme of the present invention also need increase by a cover log cabin energy conservation control computer system.This is because the operation and maintenance of travel in holiday log cabin maintenance is compared with daily local-style dwelling houses; Very big-difference is arranged: 1. as undertaking the fuel cell cogeneration system of the independently-powered heat supply of log cabin; It not only requires easy to use, and requires reliable operation, preferably accomplishes few maintenance or exempts from maintenance; Particularly when being in an emergency, can shut down automatically and also can notify relevant unit and individual the very first time, be convenient in time arrange to speedily carry out rescue work, rush to repair.2. the traveller goes out for an excursion daytime, and return to live evening.So the power supply heat supply of log cabin is the light load on daytime, evening the heavy load state.Like this, must carry out the control of daily load circulation change to cogeneration system.In addition, many tourist attractions are to belong to seasonal tourist attraction, prosperous half a year, idle half a year.Like this, it is unoccupied that the travel in holiday log cabin reaches half a year often.But relevant device is still wanted maintaining.3. the log cabin major part used of travel in holiday is placed in tourist attraction, often away from city or traffic convenience area.Liaison at ordinary times mainly relies on mobile phone; And the log cabin position is remote relatively, that is to say, and is few in the general map marked, and inconvenience is sought.4. quite a few log cabin is arranged is as the financial lease subject matter, and the mobility of log cabin, might produce can not in time locate and out of control, so the party hopes in time to control the whereabouts (and daily residential architecture can not move) of log cabin very much.For letting power supply, the heat supply of log cabin more meet the clean energy resource standard, need control computer system through energy conservation fuel cell cogeneration system and fuel gas supply system are carried out control and management under the day-to-day operation and the state of emergency.
Visible from Fig. 4; Log cabin energy conservation control computer system is set; The operating condition data acquisition of using equipment through energy supply equipment and electrical equipment to 1. log cabin; 2. energy supply and the program control of using equipment working state, 3. three aspects such as DATEL and control operation can solve the problem of above existence.The concrete introduction as follows:
1. the energy supply equipment of log cabin and electrical equipment use the operating condition data acquisition of equipment
Energy supply equipment comprises fuel cell cogeneration system and gas fuel air supply system, gathers relevant operating condition data, like generating parameters such as voltage/current, thermal parameters such as hot water temperature/flow, the flow/pressure data of natural gas; Particularly like natural gas leaking, limit data collections such as fuel cell stack operation irregularity.
The electrical equipment of log cabin uses equipment, generally is meant like household electrical appliance such as television set, refrigerator, washing machine, microwave oven, electromagnetic stove, water heaters.Can only buy the household appliances that meet energy-conservation efficiency sign at present, the data of being gathered, just live load and the better simply data of operation hours geometric ratio.
Log cabin energy conservation control computer system is gathered the said equipment related data, on the one hand as equipment routine work log record, but the usefulness of supply equipment maintenance; On the other hand; When collecting the unusual or equipment data in the hole of equipment working condition; Can handle prediction scheme according to the state of emergency of built-in computer; Send shutdown command to relevant device,, send the not normal warning message of relevant device work for log cabin everyone or control centre simultaneously through the DATEL interface.
2. energy supply and the program control of using equipment working state
Energy conservation control computer system is by preset log cabin electric power and hot water service scheme; Comprise the time period of setting with log cabin user or log cabin administrative center; As per year, monthly, until every day timing start-up and the shutdown requirement; Each running time section parameters such as power supply heat supply capacity adjustment, fuel cell cogeneration system and gas fuel air supply system are carried out program control.Equally, also can compare simple program control to the household electrical appliance of log cabin, like timing switch machine etc.
An emergent shutdown procedure is set; When receiving relevant device work condition abnormality or equipment data in the hole; Energy conservation control computer just by the risk control rank of emergent shutdown procedure, carries out the emergency processing operation to fuel cell cogeneration system and gas fuel air supply system respectively.Such as receiving the natural gas leaking alarm signal; Send the by-pass valve control out code just for the combustion gas computer in the gas fuel air supply system; Order fuel cell cogeneration system forwards stopped status to from generating; When whole systems of energy supply side can safety shutdowns and saving the troubleshooting record from damage, send to the parties concerned and to report to the police and the information of emergency processing how.
An energy-saving run program is set, and this programming thought is " demanding party decision supplier ", decides the fuel cell cogeneration system generating of log cabin and the energy of heat supply by the electric equipment actual load of log cabin.Be electricity consumption or big more with heat load, the generating of fuel cell cogeneration system is just many more with heat capacity, and vice versa.That is to say, can accomplish " what are used, send out what " that generating might reach with electricity consumption or near dynamic equilibrium.This is to be determined by the operation of fuel cells principle: the one, and fuel cell is when generating is with the light load generating at full capacity, and its generating efficiency is (differ and have only several percentage points) almost; And the conventional generator generating, when full load and light load generating operation mode, it is too big that generating efficiency differs, so in the ordinary course of things, conventional generator all requires to be operated in generating state at full capacity.The 2nd, the energy output of fuel cell can be regulated through adjustment gas supply amount.And that adjustment gas supply amount only need be regulated gas control valve door (flow valve or throttle) is just passable.
3. DATEL and control
Because log cabin building major applications is in the remote place such as landscape excursion district or mountain area, island etc. away from city and traffic main artery; Compare conventional residential housing; Supporting independently devices such as generating, heat supply in log cabin again after causing log cabin to build up and dropping into operation, must be considered: the equipment in the log cabin at ordinary times; It mainly is the whether normally operation of fuel cell cogeneration system? When breaking down; At that time, what if the locality can't in time get rid of? How does the uncommon incident that particularly happens suddenly during if any natural calamities such as illegal invasion or fire alarm, water logging, snowslides, in time report to the police? Above problem; At first be how to get in touch in the very first time with log cabin everyone or administrative center, the side might in time get help and support.
For this reason, energy conservation control computer system is provided with a log cabin equipment and reports communication interface totally three parts with User Recognition plug-in unit, a mobile data communication interface, a satellite navigation.Like this; Just can between log cabin and log cabin everyone or administrative center, set up reliable and effective writing to each other: on the one hand, in case fortuitous event appears, through built-in emergency processing program control; Can automatic or limited manual intervention; As press " warning " key mode, and just can " tell " the log cabin owner or administrative center, catastrophic failure or dangerous situation have taken place in this log cabin.On the other hand; At normal operation period at ordinary times,, can accomplish the situation of regular regular check log cabin through built-in automatic detection and touring query report program; Whether the operating mode of capital equipment such as fuel cell cogeneration system, log cabin use (living and equipment) to exceed the time limit or arrearage etc.How to realize above-mentioned communication and controlled function, further illustrate below:
A., log cabin equipment and User Recognition plug-in unit are set
This log cabin equipment and User Recognition plug-in unit at first are as the identification mark, the authority record that use this log cabin validated user, to guarantee user's rights of using and log cabin safe operation.For example, log cabin equipment essential information, comprise log cabin itself and disposed like capital equipments such as fuel cell cogeneration systems, data such as its manufacturer, product type, date of manufacture can be used as device identity to be solidificated in the plug-in unit; But about the related information that possibly exist between user and the manufacturer; Be need be when log cabin and equipment thereof are delivered for use; Formally be written in the User Recognition plug-in unit: with log cabin device product service rating subsystem is example; The user is that full payment is bought, still hire-purchase, and perhaps lease (by using timing, metering charge) is used; When the transfer equipment right of disposal perhaps comes into operation the date; More than these tracking datas can guarantee or implement and (also can be set between log cabin user and the log cabin administrative center) legitimate rights and interests between user and the manufacturer, also the data record proof is provided even can implements like technical measures such as mandatory " locked " equipment operations for both sides' standard operation.
Further, this log cabin equipment and User Recognition plug-in unit also are provided with Database Unit; It at first is to move to the Relational database subelement to the log cabin equipment operating data that energy conservation control computer is gathered and stored: the database subelement that 1. is used for equipment routine work log record with " putting into different categories "; Keep the data that moved of nearest time period by " first in first out " principle, the time period presets from several days to tens days even longer.Canned data is in this subelement; Filter through an equipment performance log program moving the equipment real-time running data come, with one day 24 hours be base, with the operating mode of the some equipment of log cabin; With the fuel cell cogeneration system is example; Like the every day of number during power generation and heat supply hour, the size of exerting oneself or what whether have fault to occur or shut down phenomenon etc.; Promptly place the criterion during as this maintenance of equipment on record as the related s main working parameters of the normal operative condition of equipment (rather than whole image data).When carrying out plant maintenance, can also call the relative recording data in the scene, implement reference as safeguarding.2. the database subelement that is used for recording equipment work condition abnormality data; Use the order of equipment by electrical equipment behind the energy supply equipment of first log cabin; In case appearance also collects the equipment working condition abnormal data; Relevant control program is given priority in arranging for these type of data is transferred to this subelement, and is compared by built-in emergency processing program.If exceed the predefined critical field of manufacturer or related fields,, or send the sound and light alarm signal by emergent risk class; Or emergent the shutdown; Or automatic log-on data telecommunication and control program, notice log cabin user, the log cabin owner and log cabin administrative center thereof.3. be used for the database subelement that the log cabin emergency rating is handled, except the equipment of log cabin might occur the emergent risk fault, log cabin itself uses log cabin and equipment as running into the user who does not obtain authorizing; More serious destroys like illegal invasion person; Local water, the fire of taking place of log cabin, natural disasters such as snowslide are by the various accident disaster transducers of log cabin energy conservation control computer system setting; Like password setting alarm, IR intrusion detector, video image identification alarm, log cabin displacement transducer etc.; In case obtain the warning message that the sensor sends, pass through the emergency processing program criterion equally, on the one hand alert data is in time stored; To start the ad hoc emergent alarm packet caller of this subelement on the other hand; Soon be stored in the information in this emergent alarm packet in advance, and access with number and character message (being fit to Beidou satellite navigation system report communication pattern) form, it is the log cabin attribute to the effect that; Like log cabin title, operating position, log cabin position, can provide by the Beidou satellite navigation location; The log cabin present situation is the equipment catastrophe failure, or illegal invasion, or natural disaster; Wherein, preceding two is to confirm in advance, solidifies relatively, and the 3rd is to be selected by the emergency processing program criterion.By the requirement of Beidou satellite navigation system report communication pattern, its data capacity is no more than 120 Chinese characters.
B, a mobile data communication interface is set
As mobile communication base station service is arranged in the log cabin location, just can with transfer of data and the reciprocal exchange of business of everyone foundation of log cabin administrative center or log cabin based on mobile communications network.This mode of writing to each other is that everybody is familiar with, this just no longer introduction more.
C, satellite navigation report communication interface is set
This is to consider, many travelling sceneries district does not have the mobile communication service, adds that log cabin can move the characteristic of arrangement, need let log cabin administrative center or log cabin everyone know the place accurate location of log cabin.Because the Beidou satellite navigation system of China is except that having the navigation and time service the same with GPS of America, its greatest feature is exactly in the report communication pattern, to have increased the SMS communication function, once can transmit the nearly information of 120 Chinese characters.Can realize exchanges data between user and the user, can be whenever and wherever possible to relevant control centre report position.Like this; Based on the report communication function of Beidou satellite navigation, navigation report communication interface via satellite not only can everyone reports its position to log cabin administrative center or log cabin; More can overcome the log cabin location does not have the defective of mobile communication service; Guaranteeing is having need the emergency risks accident take place particularly the time, and timely exchange message data in time obtain and extraneously help and support
Owing to be provided with mobile data communication interface and satellite navigation report communication interface with redundancy; Can guarantee the day-to-day operation and the contingent case of emergency of log cabin fuel cell cogeneration system, fuel air supply system and household electrical appliance fully; All under log cabin control centre or the proprietary monitoring of log cabin; In emergency circumstances; Send instruction by control centre, energy conservation control computer system receives after the instruction, through RCI the fuel cell cogeneration system is implemented emergency cutoff.Thereby improved the energy supply of log cabin greatly and used the equipment work reliability.
In the present invention, mainly form a clean energy resource system by fuel cell cogeneration system, fuel air supply system and energy conservation control computer system three parts.Adopt this clean energy resource system, even if in the place that lacks municipal administration power supply, air feed facility, like high mountain; The desert, travelling scenery districts such as island are away from the rural area in traffic lines or cities and towns; Grassland and even frontier sentry as long as have gaseous fuel and water to guarantee supply, just can provide electric power and hot water.Especially in log cabin building, compare conventional diesel generation, even wind-force, photovoltaic generation, advantages such as " environmental protection, energy-conservation, the low-carbon (LC)s, efficient " of this system is particularly outstanding:
Fuel cell power generation than traditional generation mode have more efficiently, many advantages such as environmental protection, its basic reason is that the mechanism of two kinds of generation modes is different.Fuel cell power generation is not limited by the determined hot merit transformation efficiency of Carnot cycle based on the oxidation-reduction principle of electrochemical reaction.With regard to 1,000,000 kilowatts of ' ultra supercritical ' thermal power generating technologies taking present China to grasp, though transformation efficiency up to 44%, this only is under so big generated output scale situation, could let its conversion ratio quite near Carnot cycle.If generated output is at tens kilowatts of orders of magnitude, its generating efficiency is no more than 40%; Add with electric heater (generally be converted into heat by electricity, efficient is also about 40%) to produce hot water that gross efficiency at this time is lower than 40% generating efficiency certainly.And fuel cell power generation is easy to accomplish a generating efficiency greater than 45%, and the total generating efficiency of system is greater than 70%.Such as, Osaka, Japan Gas Company introduces the fuel cell 700W fuel cell family expenses cogeneration system product of sale to the market, and its electrical efficiency is greater than 45%, and the heat efficiency (hot-water cylinder is 70 liters) is greater than 40%, and system total efficiency surpasses 85%.
This shows; In the place that does not have municipal administration power supply, air feed facility; If the fuel cell cogeneration system is selected in independently-powered, heat supply that buildings such as log cabin will be accomplished for use, the economy of its power supply heat supply and continuous considerably beyond the conventional power generation usage mode that comprises wind energy, photovoltaic.By contrast, its generating efficiency is the highest, and cost of electricity-generating is minimum, total system water saving (almost completely boiler water circulation), and the CO 2 waste gas collection rate is up to more than 90%, than being easier to accomplish low carbon emission reduction.
2. owing to be provided with log cabin energy conservation control computer system; Through fuel cell cogeneration system and log cabin energy user's the household electrical appliances and the operational data collection of hot water facility to log cabin energy supply side; Monitoring; Particularly designed an energy-saving run program; Let the energy supply and the principle of using according to " how many electricity what being sent out " of log cabin, the fuel cell cogeneration system of promptly adjusting log cabin generate electricity and the supply capacity of heat supply by the electrical equipment and the hot water facility actual load of log cabin with.The enforcement of this energy-saving run program, feasible power supply heat supply and electricity consumption might reach with heat or near dynamic equilibrium, more meet the clean energy resource requirement.This also is that the existing conventional power generation usage mode that comprises wind-force, photovoltaic at present is difficult to accomplish.
3. big in view of the log cabin mobility, dispose relatively disperse, service time changeable indefinite environmental condition; Safeguard at ordinary times and the emergency first-aid repair difficulty characteristics bigger than conventional residential building; For guaranteeing fuel cell cogeneration system reliability service; Through being provided with, can let log cabin manager that fuel cell cogeneration system and household electrical appliances and hot water facility are carried out remote monitoring based on the mobile communication two kinds of communication interfaces of communicating by letter with satellite navigation report.Especially communication mode is reported in satellite navigation; Not only solved in many travelling sceneries district or away from the outlying rural mountain area in city; Freely can't not implement the remote monitoring difficult point because of there being mobile communications network to cover to communicate by letter, and can accomplish to accurate location, log cabin position and to log cabin manager or owner's report.

Below in conjunction with accompanying drawing, the present invention is described in further detail through specific embodiment.
Embodiment 1
As shown in Figure 5, the employed clean energy resource of present embodiment system is made up of following components: the energy supply side that (1) is made up of fuel cell cogeneration system and gas fuel air supply system; (2) the log cabin clean energy resource manager who forms by the log cabin energy conservation control computer system that comprises log cabin equipment and User Recognition plug-in unit, satellite navigation report communication interface and mobile data communication interface; (3) energy user who forms by log cabin electrical equipment and hot water facility.
In log cabin, " the interconnecting " between the said equipment, the one, be the relevant water, electricity, gas pipeline configuration at center with the fuel cell cogeneration system: 1. the fuel cell cogeneration system is the rack of independently working.The fuel cell cogeneration system working machine cabinet of general several multikilowatts amasss and is equivalent to a household electric refrigerator size.After this equipment is in place; Can select the metal tube, the plastic tube that are fit to carry hot and cold water for use; The water tank of one first log cabin device or outdoor water-supply-pipe are communicated with the cold water inlet of this equipment; The hot water tap is used with the hot water outlet of this equipment and log cabin in the other end as washing one's face and rinsing one's mouth, having a bath, hot water facilities such as radiator are communicated with (referring to cold water and the delivery bearing mark shown in Fig. 5 band arrow black line).2. select suitable power cable or electric wire for use; The electric main output of fuel cell cogeneration system is linked to each other with the distribution box of log cabin, and other power consumption equipments of log cabin are all from this distribution box power taking (referring to electric power (electric main) the throughput direction mark shown in Fig. 5 band arrow black line).3. select suitable metal or plastics appendix for use, the gas inlet end of fuel cell cogeneration system is exported the port of export with the normal pressure natural gas of gas fuel air supply system be connected (referring to the natural gas transport bearing mark of Fig. 5); In addition; Can remove the air input port protection cover of fuel cell cogeneration system; Direct from the indoor air of obtaining of log cabin just as the house coal gas kitchen, perhaps receive log cabin outdoor (referring to the air throughput direction mark of Fig. 5) with suitable metal or plastics appendix.
The 2nd, be the relevant data bus configuration at center with log cabin energy conservation control computer system: log cabin energy conservation control computer system is a cover EMBEDDED AVIONICS; Can separate walls hang on the log cabin wall, also can be embedded in the rack of fuel cell cogeneration system.Log cabin energy conservation control computer system is carried out data communication, information exchange and is implemented control through various device in data/address bus and the log cabin.The major function of considering log cabin energy conservation control computer system is that the equipment to energy provider and energy user carries out data acquisition and program control.That is to say that specific to the operation of each equipment, log cabin energy conservation control computer system is not participate in the real-time control of this equipment at ordinary times, but implement to carry out by the control computer of this equipment self or devices such as industrial computer or Programmable Logic Controller.So it is not high with exchange control traffic requirement to data communication.Its data/address bus can adopt common RS-235, and RS-485 bus specification standard can certainly be selected popular CAN bus at present.Equally, because log cabin self scale of construction and little, generally speaking, connecting line can be selected twisted-pair feeder for use, and demanding occasion can be used CAN bus private mask cable.Interconnecting of log cabin energy conservation control computer system and each equipment is fairly simple, after relevant twisted-pair feeder or bus private mask cable arrangements are in place, is inserted into the attachment plug of data/address bus on the relevant device.Certainly, except the log cabin energy conservation was controlled computer system and each device hardware is connected, corresponding data communications exchange also will be embedded among each equipment with Control Software.
Although the equipment of this clean energy resource system is formed; Comprise that its operation principle and the course of work are all quite complicated; But because in log cabin energy conservation control computer system, be provided with conventional operation pattern, energy conservation model and three kinds of programs of emergency operating pattern in advance; So for the log cabin user; Use this system, as long as select " conventional operation pattern " or " energy conservation model " one of them operational mode, just as with remote controller or come the operating air conditioner device simple with the staff keypad.Do further to introduce with regard to the course of work of the employed a kind of clean energy resource of present embodiment system below:
1. conventional operation pattern
These operational mode characteristics are that log cabin energy conservation control computer system is only carried out program control and data collection task to the energy supply method, apparatus of log cabin, the energy user equipment of log cabin is only made its operation running parameter gather and record.Concrete operations are following:
(1) at first in log cabin energy conservation control computer system, by different time sections (long period with year, season, monthly be unit, the short period was a unit with one day 24 hours) cycle of operation of setting fuel cell cogeneration system.Such as, be positioned at the log cabin in alpine skiing district, possibly be the more than half a year running open, smaller part year is closed rest and reorganization.So just can set begin in the September in 1 year to the June in 1 year be the running open long period, wherein can also be subdivided into each season and month by the meteorological condition of locality, can be set at the rest and reorganization state of closing other months.In each running open long period, can also be provided with by one day 24 hours short period segmentation: as by day, the traveller goes out, and in log cabin, just can close lighting, the minimizing hot water service, and this period can be reduced power supply, heat supply is exerted oneself; When the traveller gets back to the log cabin activity, the fuel cell cogeneration system just improves power supply, heat supply is exerted oneself; To evening, its electricity consumption, with hot water and the heating demand heighten, this moment can set power supply, heat supply is exerted oneself and is reached maximum.This shows; Through control program setting to the conventional operation pattern; Can let the fuel cell cogeneration system by the different time section or put into operation, or adjust its power supply heat supply size of exerting oneself, thereby make the fuel cell cogeneration system possess preliminary intelligent power saving operation function.
(2) after the log cabin user starts log cabin energy conservation control computer system with remote controller or keyboard; The fuel cell cogeneration system is just carried out the program control instruction of conventional operation pattern of presetting in the log cabin energy conservation control computer system, gets into the conventional operation operating state of power supply, heat supply.If in its running; The log cabin user does not carry out manual intervention; The fuel cell cogeneration system will move down by the Automatic Program that log cabin energy conservation control computer system sets, and the operation sequence that sets until log cabin energy conservation control computer system is finished and out of service.
(3) log cabin energy conservation control computer system is just carried out program control operation to the fuel cell cogeneration system, and the operation of fuel cell cogeneration system is complete by the control computer of self.Meanwhile, log cabin energy conservation control computer system can be carried out the related data collecting work to the operating condition of fuel cell cogeneration system and gas fuel air supply system.The operating condition data of being gathered as the equipment routine work log record of log cabin energy supply side, are the important technology parameters that actuating equipment is safeguarded.
(4) existing fuel cell cogeneration system product has had fairly perfect job failure to detect and the emergency processing measure.Such as to faults such as gas leakage, working temperature exceed standard, all can in time report to the police or shutdown automatically.But in this clean energy resource system,, can in time store, compare and handle because the fuel cell cogeneration system operating mode service data of log cabin energy conservation control computer system to being gathered comprises the operation troubles data that possibly occur.That is to say, the troubleshooting measure of fuel cell cogeneration system self relatively, log cabin energy conservation control computer system provides redundancy backup.Further understand, ask for an interview " emergency operating pattern " content introduction.
(5) log cabin energy conservation control computer system is also to the energy user of log cabin, and like lighting, equipment such as household electrical appliance carry out the operating condition data acquisition-and-recording.
Visible in sum, the conventional operation pattern of log cabin energy conservation control computer system has tentatively embodied " environmental protection, energy-conservation, low-carbon (LC), efficient " this clean energy resource definition.Promptly adjust more easily like diesel power generation than conventional power generation usage mode, can accomplish with the time slice demand, program planning provides corresponding generating and heat supply to exert oneself at preset timed intervals.
2. energy conservation model
In order further to reach " environmental protection, energy-conservation, low-carbon (LC), efficient " definition requirement of clean energy resource; On aforesaid conventional operation pattern basis; Increase energy-saving run program control function; Develop into energy conservation model: for the energy provider of log cabin, this operational mode has been implemented " the decision supplier of demanding party " design philosophy, promptly adjusts the fuel cell cogeneration system generating of log cabin and exert oneself (power output) of heat supply by the electric equipment actual load of log cabin.For the energy user of log cabin, according to the log cabin indoor and outdoor like changes in environmental conditions such as " light strong and weak, people no one is arranged ", can accomplish " electricity consumption is with heat as required ".Simply, like " turning off the light when you leave "; Complicated, use associated appliance equipment like timesharing, especially when the equipment power consumption of log cabin exceeds fuel cell cogeneration system energy output, can let some home appliances out of service or reduce operate power.
Further specify as follows:
(1) obvious; Conventional operation pattern that energy conservation model is backward compatible; So the concrete operations mode is similar with it, the relevant method that different time sections is set the cycle of operation of fuel cell cogeneration system, the said content of the conventional operation pattern of can consulting and carrying out of pressing wherein; Newly-increased energy-saving run establishing method just confirms how to let the generating of fuel cell cogeneration system and heat supply exert oneself (power output), can real-time tracking electric equipment load variations and in time adjust.Specifically; Let the electric equipment actual load data that collect; Through log cabin energy conservation control computer system built-in energy-saving run program calculate; The fuel cell cogeneration system is sent (power output) the adjustment instruction of exerting oneself, and the fuel cell cogeneration system is adjusted its generating and heat supply power output size automatically and is guaranteed the normal power load of electric equipment then.
Built-in energy-saving run programming is according to being: the power consumption equipment power of general log cabin is all not too big, roughly at several kilowatts to the tens kilowatts orders of magnitude; In service normally, its machine utilization is relatively more balanced, only in opening of device and close moment, has certain impact load to change.So; Quantity that adjustment that the fuel cell cogeneration system only need be considered to exert oneself and power consumption equipment put into operation and load increase and decrease thereof are complementary; And the impact load of reply power consumption equipment changes; The adjustment amount of exerting oneself can have certain degree of hysteresis with regulating the speed, and concrete degree of hysteresis is through Theoretical Calculation and experiment decision by manufacturer.
(2) for the log cabin user, how to let the fuel cell cogeneration system can get into the clean energy resource operating state, it is just passable only to need button to get into " energy conservation model ".What the user more was concerned about is how effectively and rationally to use the electric equipment in the log cabin.From log cabin construction and operating cost consider; The electric equipment total load amount of log cabin configuration is greater than fuel cell cogeneration system peak power output; This is because in the ordinary course of things; The user can all not open all devices puts into operation, if this occurs, and will overload trip.But energy conservation model can improve: the one, when log cabin energy conservation control computer system detects the fuel cell cogeneration system near peak power output, can send sound and light signal prompting user, and should not insert electric equipment this moment again.The 2nd, can start electric equipment and preferentially use level allocation (timesharing use) program, perhaps close one or several electric equipment, perhaps reduce certain equipment power consumption.Specifically let which equipment preferentially use, can artificially set.The 3rd, can let the electrical outlets on the log cabin wall be divided into two types.One type is the socket of little load, can guarantee the uninterrupted electricity consumptions of equipment such as computer, sound equipment and charger that the user carries; Another kind of is the high-power electrical equipment socket, as to the electric bicycle charging, can provide prompting by log cabin energy conservation control computer system, when electric power is not enough, and can temporary interruption.
(3) " environmental protection, energy-conservation, low-carbon (LC), efficient " requirement of clean energy resource, " environmental protection, energy-conservation, low-carbon (LC) " first three items wherein mainly adopts the fuel cell cogeneration system and accomplishes.To further accomplish the 4th " efficiently " index, just must rely on " energy conservation model " operation.Adopt the fuel cell cogeneration system but also have only, just might be fairly simple and be that low cost is accomplished with " how many electricity, how much ".For no other reason than that one of maximum characteristics of fuel cell cogeneration system are exactly fuel cell when generating is with the light load generating at full capacity, its generating efficiency similar (only differing several percentage points); And conventional generator all requires to be operated at full capacity or near generating at full capacity, could keep its efficient state.
3. emergency operating pattern
The log cabin building characteristic is exactly that mobility is big, disposal disperses relatively, service time is changeable indefinite; Lacking under civil power and the pipeline gas supply condition; Log cabin also needs independent power generation and heat supply; The owner, operator and the user who adds log cabin often is not same people, so day-to-day operation, maintenance and emergency first-aid repair difficulty are bigger than conventional residential building.For guaranteeing fuel cell cogeneration system safe and reliable operation; On conventional operation pattern and energy conservation model basis; Increased the emergency operating pattern: especially when log cabin user and administrator are not same side; No matter during day-to-day operation, as natural gas occurs and use up to take a breath bottle or inflation; Still in a single day emergency episode taking place will shut down, all must the very first time notify the administrator of log cabin and let him deal with immediately.When the state of emergency of disaster took place, the log cabin user did not often also possess corresponding disposing capacity, on the contrary, must guarantee to have timely right to know especially.At this time, as let the administrator learn to notify the log cabin user again after this state of emergency information, often have little time.Just need through operation emergency operating pattern, on the spot, the very first time sends warning signal automatically, can let the log cabin user in time flee from, and avoids personal injury.
Obvious, for information about or data by after the collection of log cabin energy conservation control computer system, be transplanted on and carry out information state identification processing in log cabin equipment and the User Recognition plug-in unit.If the normal data conclusion does not need manual intervention, just can be used as routine work log record storage; If abnormal data conclusion; The log cabin energy conservation is controlled computer system or fuel cell cogeneration system self error correction, has been got rid of not; Just, let them in time arrive on-the-spot the solution through mobile data communication interface or the satellite navigation report communication interface notice log cabin owner and management side.Such as, simple case is that natural gas has been used up, and needs ventilation bottle or inflation.The normal very important person of this type also can be one of emergency processing operation to the in-situ processing business.Another kind is real emergency processing; The abnormal data conclusion that is promptly drawn is to belong to urgent or high-risk degree or like illegal invasion and disaster; Log cabin energy conservation control computer system is sent the emergency treatment instruction on the one hand; Such as shutdown, close the natural gas valve, send the acousto-optic warning signal and tell the log cabin user; On the other hand, also be to carry out mobile communication synchronously to communicate by letter with the satellite navigation report, tell the log cabin owner and management side the above information very first time, let them arrive field first aid immediately and handle.At last, other additional extension functions can also be arranged, as detect relevant device and arrived the normal repairing phase, need the notice log cabin owner or management side; The log cabin user is because of arrearage or exceed the time limit, and need stop its right to use, and also can notify related fields this moment, even where necessary, can communicate by letter strange land enforcement mandatory " locked " equipment operation technical measures through mobile communication with the satellite navigation report.
