SPEEDTRONIC ™ Mark V Gas Turbine Control System yog qhov tseeb derivative hauv SPEEDTRONIC ™ series zoo heev. Cov txheej txheem ua ntej tau ua raws li kev tswj hwm lub tshuab hluav taws xob tsis siv neeg, kev tiv thaiv thiab kev sib txuas cov txheej txheem yos rov qab rau xyoo 1940s lig, thiab tau loj hlob thiab tsim nrog cov cuab yeej muaj. Kev siv hluav taws xob turbine tswj, kev tiv thaiv thiab kev sib txuas tau pib nrog Mark I system hauv 1968. Mark V system yog kev siv digital ntawm cov turbine automation cov tswv yim kawm thiab ua kom zoo dua hauv ntau dua 40 xyoo ntawm kev ua tiav, ntau dua 80% ntawm cov uas tau ua tiav. los ntawm kev siv tshuab hluav taws xob tswj.

Lub SPEEDTRONIC ™ Mark V Gas Turbine Control System siv cov thev naus laus zis hauv lub xeev tam sim no, suav nrog triple-redundant 16-ntsis microprocessor controllers, ob-tawm-ntawm-peb kev pov npav rov ua dua ntawm kev tswj xyuas tseem ceeb thiab kev tiv thaiv tsis zoo thiab Software-Implemented Fault Tolerance (SIFT). Qhov tseem ceeb tswj thiab kev tiv thaiv sensors yog triple redundant thiab pov npav los ntawm tag nrho peb cov txheej txheem tswj. Cov teeb liab tso tawm tau raug xaiv los ntawm theem kev sib cuag rau cov solenoids tseem ceeb, ntawm qib logic rau cov khoom sib txuas ntxiv thiab ntawm peb lub coil servo li qub rau cov teeb liab tswj analog, yog li ua kom muaj kev tiv thaiv thiab kev ua haujlwm siab tshaj plaws. Ib qho kev tiv thaiv kev ywj pheej muab triple redundant hardwired nrhiav tau thiab kaw ntawm overspeed nrog rau kev ntes nplaim taws. Qhov no module kuj synchronizes lub turbine generator rau lub hwj chim system. Synchronization yog thaub qab los ntawm kev txheeb xyuas muaj nuj nqi hauv peb cov txheej txheem tswj hwm.

Mark V Control System yog tsim los ua kom tiav tag nrho cov roj turbine tswj cov cai. Cov no suav nrog kev tswj cov kua, roj lossis ob qho tib si roj raws li cov kev xav tau ntawm kev ceev, kev tswj kev thauj khoom raws li kev thauj khoom ib feem, tswj qhov kub thiab txias nyob rau hauv qhov muaj peev xwm siab tshaj plaws lossis thaum lub sijhawm pib ua haujlwm. Tsis tas li ntawd, inlet qhia vanes thiab dej los yog chav txhaj tshuaj yog tswj kom tau raws li emissions thiab kev khiav hauj lwm yuav tsum tau. Yog tias kev tswj cov pa hluav taws xob siv Dry Low NOx cov tswv yim, roj staging thiab combustion hom yog tswj los ntawm Mark V system, uas tseem saib xyuas cov txheej txheem. Sequencing ntawm cov auxiliaries tso cai rau tag nrho automated startup, shutdown thiab cooldown kuj raug tswj los ntawm Mark V Control System. Turbine tiv thaiv kev ua haujlwm tsis zoo thiab kev tshaj tawm ntawm cov xwm txheej txawv txav tau muab tso rau hauv lub hauv paus system.
