The Proton Exchange Membrane Fuel Cells generation technology be development in recent years than faster more a kind of generation mode, it has characteristics such as startup is fast, the working temperature requirement is low, specific power is big, efficient is high, pollution-free, in fields such as aviation, submarine, compact power, automobiles application is arranged all.Therefore, can not satisfy at batteries provides power supply to this problem of transformer station for a long time, and we propose used in proton exchange membrane fuel cell in conjunction with storage battery, to guarantee transformer station's long-play more reliably in emergency power supply of transforming plant.Simultaneously, the fuel cell conveniently moving also can be used as transformer station portable portable power source power station.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
Please refer to shown in Figure 1ly, it is a kind of embodiment of the present invention, and it discloses a proton exchanging film fuel battery as the emergency power supply of transforming plant system, and it comprises emergency power supply unit 1, fuel cell supplementary controlled system 2 and warning system 3, wherein:
3 liang of outputs of fuel cell supplementary controlled system 2 and warning system link to each other by PC 4, and fuel cell supplementary controlled system 2 links to each other with the input and the output of emergency power supply unit 1 with the input of warning system 3.
The input variable of described fuel cell supplementary controlled system 2 mainly comprises: voltage 25 and electric current 26, tail gas air pressure 27 and the exhaust temperature 28 of air or oxygen air pressure 21, air or oxygen flow 22, hydrogen flowing quantity 23, hydrogen gas pressure 24, fuel cell pack output.
During use, the using method of described fuel cell supplementary controlled system, it mainly may further comprise the steps:

(2) the PID initial value is set, adds regularly simultaneously and interrupt, make it the same with the PID sample rate;
(3) calculate air/hydrogen entraining air stream amount PID set point according to the load voltage electric current;
(4) controller output PID analog quantity regulating system parameter.
By air pressure, the flow control of above-mentioned steps realization to hydrogen and air, we can adjust the generated output of fuel cell.When load becomes big, we increase the input air pressure and the flow of hydrogen and air, and vice versa.In order to prevent that output voltage, electric current from surpassing our tolerance scope and control range, we need detect output voltage, electric current; For the operate as normal (60 ℃-70 ℃ of working temperatures) that guarantees heat exchanger, we need detect exhaust temperature, thereby guarantee the efficiently radiates heat of cooling system.
The input variable of described warning system 3 mainly comprises: voltage 25 and electric current 26, tail gas air pressure 27 and the exhaust temperature 28 of air or oxygen air pressure 21, air or oxygen flow 22, hydrogen flowing quantity 23, hydrogen gas pressure 24, fuel cell pack output.
During use, the power of fuel cell can change along with flow, the pressure of the gas that becomes a mandarin, yet the fuel cell of different capacity has the highest delivery rate and a pressure.Such as the Proton Exchange Membrane Fuel Cells of a 10kW, its highest hydrogen supply ability is 100L/min, and air is 540L/min; And that their supply pressure all requires in the 0-1 atmospheric pressure is adjustable.So in case the power speed of hydrogen or air and gas pressure surpass prescribed limit, we just need report to the police by our warning system.

Described batteries 6 is two groups.
During use, traditional emergency power supply of transforming plant is mainly storage battery power supply, yet that it has power-on time is limited, the difference between current that withstands shocks, shortcoming such as can not be with high-power load, can not move.At these shortcomings, we propose the fuel cell power generation station is used for emergency power supply of transforming plant, guarantee the long-time steady operation of system.Under the initial condition, switch S 1, S2 disconnects.1# advances electricity supply # 1 bus load power supply and to #1 batteries floating charge during operate as normal, and 2# advances electricity supply # 2 bus load power supply and to #2 batteries floating charge.When #1 advanced electrical anomaly, the #1 storage battery at first uninterruptedly provided #1 bus load power supply, and simultaneously the fuel cell power generation station starts rapidly, ran to close S1 supply # 1 bus load power supply and to #1 batteries floating charge jointly.When #2 advanced electrical anomaly, the #2 storage battery at first uninterruptedly provided #2 bus load power supply, ran to close S2 fuel cell power generation station supply # 2 bus load power supply and to #2 batteries floating charge simultaneously jointly.In case # 1 advance electricity, #2 advance electricity recover normal after, then cut-off switch S1, S2 stop the fuel cell power generation station, move with normal mode.Fuel cell has the ratio of startup very fast (several seconds), characteristics such as specific power is big, efficient height, it and the public rectification inverter circuit of batteries, this has just reduced cost, this execution mode, reliably providing for a long time of transformer station's emergency power supply under any circumstance has been provided for fuel cell power generation station and storage battery complementary cooperation.
Simultaneously, with reference to shown in Figure 4, in our emergency power system based on Proton Exchange Membrane Fuel Cells had been included in equipment such as DC/AC, DC/DC, various emergent loads can directly be with in output.
Emergency power supply unit output electric energy is divided into three parts: first is as communication power supply, select corresponding D C-DC module according to the communication voltage requirements, if our fuel cell output voltage 100V, communication voltage is 48V, and then we select the DC-DC module of 100V-48V; Second portion makes us obtain the direct current of different voltages by step-down silicon chain, has satisfied the demand of different electricity consumptions, as fire emergency lamp, broadcaster, warning power supply etc.; Third part is exactly an inverter circuit, and the alternating current with dc inversion becomes us to need can be applicable to as main transformer cooler, fire pump etc.Compare with commonly using, it can overcome storage battery can not power for a long time to the defective of transformer station, can guarantee transformer station's long-play more reliably.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, wish that appended claim comprises these distortion and variation and do not break away from spirit of the present invention.
