In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings by way of examples.
As shown in fig. 1 and 2, the present invention provides a method for accurately obtaining the output current and output power relationship of a fuel cell system, which comprises the following steps:
the method comprises the following steps: selecting a proper curve function equation to be fitted based on a polynomial fitting method and combined with experience according to a fuel cell system output current-output power characteristic curve obtained by a calibration experiment;
in this embodiment, a nearly linear relationship between the output current and the output power obtained by the calibration experiment is shown in fig. 3, and a function of a curve to be fitted is empirically selected as:
y=ax3+bx2+cx+d
wherein y represents the output power value, x represents the output current value, and a, b, c and d are parameters to be fitted.
Step two: combining experiments and simulink modeling simulation to obtain the output current value and the output power value of the fuel cell system;
in this embodiment, the fuel cell stack with a rated power of 62kW is selected for the experiment, and the fuel cell stack is subjected to the pressure rise and pressure drop experiment by changing the current density, so as to ensure the reaction temperature and environment of the hydrogen and oxygen reactants, and the flow rate of the circulating water is appropriately adjusted according to the temperature of the hydrogen and oxygen in and out of the stack during the pressure rise process.
Taking the process that the output current of the electric pile is increased from 211A to 326A, and the output power is increased from 42kW to 62kW as an example, in the process, the circulating water flow is adjusted from 70kg/s to 150kg/s so as to ensure that the voltage of a single fuel cell is stable, and the temperature difference between the inlet and the outlet of the fuel is within 10 degrees.
In this embodiment, a proton exchange membrane fuel cell model is established in simulink to perform simulation, and simulation under different working conditions is realized by changing the fuel inlet pressure.
In this embodiment, in the simulink simulation model of the fuel cell stack, the reaction speed may be increased by increasing the pressure of fuel entering the stack, and at this time, the voltage decreases, the current increases, and the current variation value is greater than the voltage variation value. Therefore, the output power increases according to P ═ I × V.
In the present embodiment, the fuel cell simulation is performed under pressures of 1atm, 2atm, and 3atm, respectively, to obtain the output current and the output power value, the relation between the output current and the output power can be changed by changing the stack-entering pressure, and when the output current is 103A, the output powers corresponding to the pressures of 1atm, 2atm, and 3atm are 21.25kW, 22.65kW, and 23.65kW, respectively.
Step three: and searching a parameter optimal solution in the curve function to be fitted by adopting a Particle Swarm Optimization (PSO) algorithm according to the obtained output current value and output power value.
In the embodiment, a Particle Swarm Optimization (PSO) algorithm is adopted to fit the multi-parameter curve, so that the probability of local optimum can be reduced, and the reliability of the fit parameters can be improved.
The particle swarm algorithm comprises the following specific calculation steps:
step 201: initializing a solution space, and setting the particle size, the particle dimension, the maximum speed setting of each dimension of the particle and the maximum iteration times of the particle;
in this example, the particle size M is set to 300, the particle dimension n to 4, and the maximum velocity V is set according to the function of the selected curve to be fittedmax1, maximum number of iterations Tmax=1000。
Step 202: randomly initializing the velocity v of each solution in a particle swarm search space0And position x0Calculating an adaptive function value f0Obtaining the individual extreme value of the particle and the global optimal position of the group, Pid=x0The global extreme value is equal to the individual extreme value;
the particle velocity and position update formulas are respectively:
Vid=ωVid+C1random(0,1)(Pid-Xid)+C2random(0,1)(Pgd-Xid) (1-1)
Xid=Xid+Vid (1-2)
wherein, VidIs the particle velocity, XidAs the current position of the particle, PidIs an individual extremum, PgdIs a global extremum.
Omega is an inertial weight factor, and C1 and C2 are an individual learning factor and a global learning factor respectively.
In this embodiment, the inertial weight factor, the individual learning factor, and the global learning factor are set to have a classical setting ω of 0.729 and c1 of c2 of 1.4962.
The way of verifying the fitting effect is as follows: substituting current parameter value into power value PrObtaining a current value IeCalculating the current value and the work in experimental and simulation dataRate PrCorresponding current value IrThe deviation therebetween. In this example, therefore, the selected fitness function is:
wherein e represents the parameters a, b, c, d.
Step 203: each particle is based on its own individual extremum and global optimum solution, according to equations (1-1) and (1-2) of claim 3, on the update speed v1And position x1;
The fitness function represents x under the current fitting parametersiCorresponding fiValue (i.e. power value P)rCorresponding fitting current value Ie) And reality yiValue (i.e. this power value P)rCorresponding actual current value Ir) And so a smaller fitness function value indicates a higher individual fitness.
Step 204: calculating a fitness function value f of the particle′Comparison of f′And f0If f is′<f0Let f0=f′And updating individual extreme value P of the particleid=x1In this case, the global optimum position is the position P where the particle having the smallest fitness function value is locatedgd=xfmin;
Step 205: judging whether the iteration times meet the maximum iteration time value set in Step201, if so, performing Step S206, otherwise, performing Step S203;
step 206: and outputting four corresponding parameter values when the fitness function value is minimum.
In this example, a fuel cell output current-output power characteristic curve obtained by fitting experimental test data is shown in fig. 4.
In this embodiment, the fuel cell simulation was performed under pressures of 1atm, 2atm, and 3atm, the output current and the output power value were obtained, and the output current-output power characteristic curve of the fuel cell obtained by fitting is shown in fig. 5.
