The second dynamometer instrument 24 can have the structure identical with the first dynamometer instrument 23, and is arranged on load line 241 to measure the load electric P2 that user was used.This load line is for being supplied to commercial power and production electric power P1 user's load 25 from system power supply and electric power converter 20.Therefore, fuel cell controller 50 can be more than predetermined time during in, the production electric power P1 of fuel cell that relatively the first dynamometer instrument 23 is measured and the unbalance difference of electric power (△ P=P2-P1) between the user's that the second dynamometer instrument 24 is measured load electric P2.
The system 100 of one embodiment is associated with fuel cell 10 and system power supply (for example, source power supply), and optionally by producing electric power P1 and commercial power, turns round.Be system 100 when starting fluid battery 10, by the commercial power of system power supply, turned round, and produced in the operation process of electric power by fuel cell 10, by the production electric power P1 of fuel cell 10, turned round.
For this reason, power distributor 30 is disposed between fuel cell 10 and system power supply, makes commercial power can be supplied to fuel cell 10.Be that power distributor 30 is along with startup or the running of fuel cell 10, optionally by commercial power with produce electric power P1 and be supplied on other member of system.

Fuel cell controller 50 carrys out the economy of raising system 100 by the unbalance difference of electric power (△ P=P2-P1) between the elimination production electric power P1 of fuel cell 10 and user's load electric P2.And, consider that the commercial power of system power supply is suitable for progression expense system, fuel cell controller 50 preferably makes commercial power be used in low price scope.
For this reason, fuel cell controller 50 comprises: load tracking device 51, economy identifier 52, running controller 53 and data random asccess memory (RAM) 54.Load tracking device 51 is according to the unbalance difference of electric power (△ P=P2-P1) the judgement electrical production direction of producing electric power P1 and load electric P2.Economy identifier 52 is by relatively the production power price MWP of fuel cell 10 and the commercial power price WP of system power supply identify economy.Running controller 53 is in view of the change of load electric P2, and corresponding to specified generating, substep is controlled the electrical production stage of fuel cell 10, and the production electric energy of fuel cell 10, the flow of Linear Control generating raw material, air and cooling water.More specifically action effect as for to fuel cell controller 50, describes in connection with control method.
Fig. 2 is the flow chart of the control method of fuel cell co-generation unit shown in presentation graphs 1 schematically.Visible with reference to Fig. 2, the control method of the fuel cell co-generation unit of an embodiment (calling " control method " in the following text), comprising: the first calculation procedure ST10, the second calculation procedure ST20, economic analysis step ST30 and electric power supplying step ST40.
The price of the production electric power P1 that the first calculation procedure ST10 computing fuel battery 10 is produced produces power price (MWP).In the first calculation procedure ST10, detect use amount, the cost of material FP (price/Nm of unit of generating raw material F
3) and produce electric energy ST11, and calculate and produce power price MWP(ST12 by these data).
For example, if fuel cell 10 was produced the generating raw material that the electric energy of P kWh uses in 1 hour, be F (Nm
3), unit generating cost of material be FP (won/Nm
3), the production power price MWP of fuel cell 10 is F * FP/P (won/kWh).
The second calculation procedure ST20 calculates the price of the commercial power of the system power supply of using, i.e. commercial power price WP.The second calculation procedure ST20 comprises: unbalance difference calculation procedure ST21, the unbalance difference of electric power (△ P=P2-P1) of the production electric power P1 of computing fuel battery 10 and load electric P2; Scope determining step ST22, judges whether the unbalance difference △ P of electric power exceeds predetermined range of set value; Electrical production step ST23, if the unbalance difference △ P of electric power falls in predetermined range of set value, reduces and produces electric power P1, if the unbalance difference △ P of electric power exceeds predetermined range of set value, increases and produces electric power P1; Integrating step ST24, integrating (∫ △ P) that be supplied to the commercial electric energy corresponding commercial power of unbalance difference △ P; And calculation procedure ST25, by comparing commercial electric energy and the progression expense system of institute's integrating, calculate commercial power price WP.
In economic analysis step ST30, by relatively producing power price MWP and commercial power price WP (ST31), thereby judgement is for identifying the economy index (EW=MWP-WP) of producing power economy for just (+) or bearing (-) (ST32).
Data random asccess memory (RAM) 54 for store real-time use system power supply the commercial electric energy (∫ △ P) of integrating and as the commercial power price WP in each progression interval of the systematic electricity of progression expense system.Therefore, economy identifier 52 calculates commercial power price WP in real time by the commercial electric energy (∫ △ P) of integrating, and compares with the production power price MWP of fuel cell 10, thereby judges economy index E W and send it to running controller 53.
In electric power supplying step ST40, when economy index E W is during for just (+), commercial power is supplied to (ST41) in load 25, when economy index E W is during for negative (-), production electric power P1 is supplied to (ST42) in load 25.That is, economy index E W is that just (+) means that the production power price MWP of fuel cell 10 is more expensive than the commercial power price WP of system power supply, therefore relatively cheap commercial power is supplied in load 25.And economy index E W means that for negative (-) the production power price MWP of fuel cell 10 is cheaper than the commercial power price WP of system power supply, therefore relatively cheap production electric power P1 is supplied in load 25.Therefore, system 100 has economy.
Fig. 3 is the commercial power of comparison system power supply and production electric power electric energy separately and the curve chart of power price of fuel cell.With reference to Fig. 3 illustrate one for example under: in the second calculation procedure ST20, electrical production step ST23 comprises first to fourth electrical production step ST231, ST232, ST233, ST234.
For convenience of explanation, commercial power price WP is called to uniform quotient electric energy Pe with production power price MWP consistent commercial electric energy in set point.For example,, by order to judge that the time whether and in advance the generation of the unbalance difference △ P of electric power is set is made as 5 minutes to 10 minutes.
In the first electrical production step ST231, if the commercial electric energy using in being less than the scope of Pe/3, is produced the production electric power P1 fewer than actual loading electric energy, so that the unbalance difference △ P of electric power is specified generating 3/10.
In the second electrical production step ST232, if the commercial electric energy using more than Pe/3 and be less than in the scope of 2Pe/3, is produced the production electric power P1 fewer than actual loading electric energy, so that the unbalance difference △ P of electric power is specified generating 2/10.
In the 3rd electrical production step ST233, if the commercial electric energy using more than 2Pe/3 and be less than in the scope of Pe, is produced the production electric power P1 fewer than actual loading electric energy, so that the unbalance difference △ P of electric power is specified generating 1/10.
In the 4th electrical production step ST234, if the scope of the commercial electric energy using more than Pe produced the production electric power P1 that can eliminate the unbalance difference △ P of electric power.
That is,, in electrical production step ST23, when controlling commercial power use amount, in the mode moving to optimization procedure, control, thereby make it reach commercial power price WP and the consistent uniform quotient of fuel cell manufacture power price MWP electric energy Pe.In view of the hot production prices HP that fuel cell 10 is produced, can raise and produce power price MWP, the uniform quotient of system power supply can move to new electric energy Phe (with reference to Fig. 3) for uniform quotient with electric energy Pe thereupon.Thus, the electric power that the system 100 of an embodiment can be eliminated between the production electric power P1 of fuel cell 10 and user's load electric P2 is unbalance, thereby has economy.
For another example, because user's load electric change, electrical production step ST23 can be divided into 9 steps of specified generating (for example, when specified generating is 1000W, be divided into 100W, 200W, 300W, 400W, 500W, 600W, 700W, 800W, 900W and 1000W), and produce electric power P1 by fuel cell 10.In electrical production step ST23, if more than predetermined setting-up time during in, it is more than 1/10 that predetermined production electric energy and the unbalance difference △ P of electric energy loaded electric power are specified generating, moves to next step and produce electrogenesis power P1 next life.Now, the production electric energy that fuel cell 10 is produced, generating raw material, the air that is supplied to fuel cell pack and cooling water flow produce linear change.
Below, take for example, the commercial electric energy of system power supply based on applicable progression expense system (Korean Electric Power Company) and the commercial power price in each progression interval to describe as example.
As shown in table 1, when using 1Nm
3generating raw material (for example town gas) while producing the production electric power P1 of 4kWh, if town gas price is 670 yuan/Nm
3, in the interval of 0kWh to 200kWh, produce power price MWP=670 * 200/4=33500 unit, so the commercial power price of system power supply (WP=55.1 * 100+113.8 * 100=16890 unit) is well below producing power price.In Fig. 3, electric energy (kWh) 0 to Pe.
As mentioned above, the control method of an embodiment is preferentially used the commercial power of system power supply, until the production power price MWP of commercial power price WP monthly and fuel cell is consistent, thereby reduces to greatest extent energy expenditure.For example, monthly can within the scope of the use amount of 0.5 * Pe to 0.9 * Pe, use the commercial power of system power supply.
And, the production power price MWP that the system 100 of one embodiment and control method comparison are calculated by the cost of material that generates electricity and the commercial power price WP of system power supply and the new renewable energy resources are (for example, wind-force, sunlight etc.) production power price, make it possible to use the new renewable energy resources, and can further improve economy when adopting the new renewable energy resources.
Above preferred embodiments of the present invention have been disclosed for illustrative, but the present invention is not limited thereto, in the scope of claims and specification and accompanying drawing, can be out of shape in every way and implement, and this distortion is naturally within the scope of the present invention.
