Accompanying drawing explanation
Fig. 1 is the schematic diagram of the fuel cell control method with full-automatic power supply power-off.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described further.
Embodiment 1
A kind of method for controlling power supply of fuel cell system, flow process is as it is shown in figure 1, comprise the following steps:
1, civil power power-off whether detection, hydrogen supply pressure detecting.
Mains-supplied situation, under mains-supplied normal condition, not starting fluid battery is detected by civil power detection module
Electricity generation system generates electricity；Under civil power powering-off state, during backup battery voltage >=51.5V, do not start.At civil power powering-off state
Under, and whether backup battery voltage is < during 51.5V, by hydrogen supply pressure detecting module detection hydrogen-feeding system pressure more than 1MPa, inspection
It is yes for surveying result, and starting fluid battery generating system generates electricity.Testing result is no, not starting fluid battery generating system,
And carry out alarm.
Wherein, hydrogen-feeding system divides three road hydrogen supply gas circuits, gas circuit 1, gas circuit 2 and common road gas circuit, gives fuel cell hydrogen-feeding respectively,
When the gas of gas circuit 1 makes to be finished, automatically switching to gas circuit 2 and supply, switching carries out alarm simultaneously, and operator the most more take a breath
Bottle, it is ensured that the amounts of hydrogen of supply.
2, fuel cell generation starts, and exports electric energy.
Fuel Cell Control System is run, and the electric energy of output is by output system supply arrangement, and detailed process is as follows:
1) start: air-valve on and off switch is opened, air-valve controls switch and opens, timing 2min, timing 10s, two kinds of timing and simultaneously
Carry out；The 2min time arrives, and air-valve on and off switch is closed.The 10s time arrives, and judges two gas circuit pressures, gas circuit 1 pressure simultaneously >=1Mpa with
And gas circuit 2 pressure>=1Mpa, when gas circuit 1 pressure>=1Mpa time, it is judged that whether<gas circuit 2 pressure, is to open gas to gas circuit 1 pressure
Road 2 electromagnetic valve, otherwise opens gas circuit 1 electromagnetic valve, and then gas circuit valve state is ON, timing 10s；When gas circuit 1 pressure < during 1Mpa,
Turn off gas circuit 1 ventilation to report to the police；Whether judge gas circuit 2 pressure>=1Mpa is whether then judge gas circuit 1 pressure<gas circuit 2 pressure, mistake
Journey, with aforementioned, otherwise turn off gas circuit 2 ventilation and reports to the police.The 10s time arrives, it is judged that 0.6bar≤admission pressure≤1.5bar, is to enter
Air valve is opened, timing 0.1s, and blower fan opens 15% simultaneously, otherwise closes gas circuit 2 and ventilates, reports to the police；The 0.1s time arrives, exhaust valve open,
Timing 2s；The 2s time arrives, exhaust valve close, time delay 10s；The 10s time arrives, and short switch is opened, timing 20ms；The 20ms time arrives,
Short switch cuts out, time delay 2s；The 2s time arrives, and air bleeding valve is opened, timing 0.25s；The 0.25s time arrives, exhaust valve closure, time delay
5s；The 5s time arrives, and short switch is opened, timing 200ms；The 200ms time arrives, and short switch cuts out；Timing 2s, the 2s time arrives,
Air bleeding valve is opened；Timing 0.25s, the 0.25s time arrives, exhaust valve closure；Judge FC voltage >=50V, otherwise closes, the bad report of FC
Alert；It is that FC output switch is opened；Time delay 5s, the 5s time arrives, and DC/DC switch is opened；Time delay 5s, the 5s time arrives, and measures FC electricity
Pressure, electric current；Judge FC voltage >=30V, otherwise turn off, FC is bad to report to the police；It is to calculate P；Aerofluxus interval 15s and evacuation time
0.25s；Timing runs 2min；The 2min time arrives, and fuel cell operation is normal；Start terminates.
2) FC normal power generation: FC normal operation, FC current measurement value, FC voltage measuring value；Judge FC voltage >=30V, no
Then turn off, undervoltage warning；Being to perform: corresponding air bleeding valve opening time simultaneously, run interval time, corresponding temperature desired value is transported
OK, fuel cell runtime, FC short circuit operation, gas switchover operation；Then FC electric current is judged > 65A, it is to turn off, crosses stream
Report to the police.
Air bleeding valve runs: 0A < FC current value≤19.5A, exhaust valve open；Timing 0.25s, the 0.25s time arrives, air bleeding valve
Close；Timing 30s.19.5A < FC current value≤39A, exhaust valve open；Timing 0.25s, the 0.25s time arrives, exhaust valve close；Timing
20s.39A < FC current value≤65A, exhaust valve open；Timing 0.25s, the 0.25s time arrives, exhaust valve close；Timing 15s.
Fan operation: 0A < FC current value≤6.5A, FC temperature target=43 DEG C, PWM controls rotation speed of fan, and FC temperature is surveyed
Value > 58 DEG C, turn off；The too high warning of FC temperature.6.5A < FC current value≤13A, FC temperature target=44 DEG C, PWM controls wind
Machine rotating speed, FC measured temperature > 58 DEG C, turn off；The too high warning of FC temperature.With this principle, the most persistently judge FC current value district
Between, and FC temperature target, last interval is 58.5A < FC current value≤65A, FC temperature target=52 DEG C, and PWM is controlled
Rotation speed of fan processed, FC measured temperature > 58 DEG C, turn off；The too high warning of FC temperature.
Short circuit operation: run time timing, timing 30min, the 30min time arrives, and short switch is opened；Timing 10ms.
Gas switchover operation: judge that gas circuit state is No. 1 use, be then to judge No. 1 pressure > 0.1Mpa, otherwise judge No. 2
Pressure > 0.1Mpa, No. 1 pressure > 0.1Mpa and No. 2 pressure > 0.1Mpa is when being no, and turn off gas circuit 1 and gas circuit 2, report to the police.No. 1
Pressure>0.1Mpa is yes, then<0.8Mpa, No. 1 gas circuit ventilation reports to the police, No. 1 pressure<0.5Mpa, gas circuit 1 electromagnetism to judge No. 1 pressure
Valve time delay 2s closes；Gas circuit 2 electromagnetic valve is opened.No. 2 pressure>0.1Mpa is yes, then judge No. 2 pressure<0.8Mpa, No. 2 gas circuits
Ventilation is reported to the police, and < 0.5Mpa, gas circuit 2 electromagnetic valve time delay 2s close No. 2 pressure；Gas circuit 1 electromagnetic valve is opened.
3, after civil power powers on, closing fuel cell generation, equipment is in holding state, does standard for power-off next time
Standby.
After civil power powers on, after civil power detection module detects that civil power powers on, close fuel cell generation, open heat radiation
Exhaust fan, closes hydrogen-feeding system, is then shut off electric energy output system, when the temperature of fuel cell is down to 40 DEG C, closes heat radiation
Exhaust fan, out of service, equipment is in holding state, prepares for civil power power-off next time.
