Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the schematic diagram of fuel gas generation unit.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
As shown in Figure 1, a kind of fuel gas generation unit control system, has central control unit 25, central control unit links to each other with relay 27, full electric weight detection module 22, synchronous detection module 23, speed control 24 respectively, control system inserts supply network 26 by relay 27, and relay 27, full electric weight detection module 22 all link to each other with generator 19 with synchronous detection module 23; Speed control 24 also links to each other with the gaseous mixture electric butterfly valve 10 of first velocity transducer 13 and gas engine 5 respectively; Central control unit 25 is realized bidirectional data exchange and instruction transmission also by carrying out communication between RS485 and unit parameter collection and the control cubicle 3; Unit parameter collection and control cubicle 3 also respectively be arranged on fuel gas pipeline on electromagnetically operated valve 1, starter motor 14 and lubricating oil pump motor 12 be connected; Combustion Process Control cabinet 18 connects with each ignition coil, transducer 7, the combustion gas electric butterfly valve 4 that phase detector 17, TDCS TDC Sensor 16, second speed transducer 15 are connected, are arranged on the gas engine respectively.
Said structure has been formed four control system of fuel gas generation unit: igniting and auxiliary fuel supply-system, unit parameter collection and control system, governing system and four control system of electric generation management control system.
Native system also can constitute identical several fuel gas generation units by fuel gas generation machine set system in parallel a plurality of and shown in Figure 1 on supply network, each fuel gas generation unit is connected with the engineer station by router access industrial Ethernet.
The system start-up flow process is as follows:
System judges whether to assign starting command, if then opens solenoid valve 1, starter motor Oil pump electrical machinery 12, judge whether open the machine condition satisfies: if do not satisfy, report to the police and show fault condition, close electromagnetically operated valve, the lubricating oil pump time-delay stops, assigning again and open the machine order; If satisfy, starter motor 14 runnings, judge that rotating speed is whether greater than 200rpm: if not, then starter motor remains in operation; If then starter motor cuts out, and judge that rotating speed is whether greater than 400rpm: if not, then start failure and report to the police, and whether judge the number of starts, if then close electromagnetically operated valve, lubricating oil pump and delay time and stop, waiting for assigning again and open the machine order greater than 3 times; If not, then the lubricating oil pump time-delay stops, starting time-delay, restarts lubricating oil pump; If then lubricating oil pump stops, opening the machine task termination.
The system-down flow process is as follows:
System judges whether to assign halt command, if, power (control speed regulator) then falls, judge whether power arrives desired value: if not, then continue to fall power; If, breaker open operation then, rotating speed (control speed regulator) falls in engine no-load running 5 minutes, and the engine idle operation judges whether to reach halt condition: if not, the engine idle operation; If, then close electromagnetically operated valve, the lubricating oil pump operation is arrived up to the lubricating oil pump operation delay time of setting, and lubricating oil pump stops, and shuts down task termination.
System's flow process in parallel is as follows:
Whether system judges engine according to normal speed no-load running, if then carry out synchronous detecting, judges whether synchronously: if not, then finely tune speed regulator, proceed synchronous detecting then; If then breaker closing by control speed regulator power per liter, compares his acc power, carries out power division, task termination in parallel by the control speed regulator.
