I-SPEEDTRONIC™ Mark V Gas Turbine Control System iphuma kwakamuva ochungechungeni lwe-SPEEDTRONIC™ oluphumelele kakhulu. Izinhlelo ezandulele zazisekelwe ekulawuleni okuzenzakalelayo kwe-turbine, ukuvikela kanye namasu okulandelanisa asukela ngasekupheleni kwawo-1940, futhi asekhulile futhi athuthukiswa ngobuchwepheshe obukhona. Ukuqaliswa kokulawulwa kwe-electronic turbine, ukuvikelwa nokulandelanisa kwaqala ohlelweni luka-Mark I ngo-1968. Uhlelo lwe-Mark V luwukuqaliswa kwedijithali kwamasu okuzenzakalela kwe-turbine afundwe futhi acwengisiswa eminyakeni engaphezu kwengama-40 yesipiliyoni esiyimpumelelo, ngaphezu kwama-80% ayo asebekhulile. ngokusebenzisa ubuchwepheshe bokulawula ngogesi.

I-SPEEDTRONIC™ Mark V Gas Turbine Control System isebenzisa ubuchwepheshe bamanje besimanje, okuhlanganisa izilawuli ezincane ze-16-bit microprocessor ezingasadingeki ngokuphindwe kathathu, ukungadingeki kokuvota okubili kokuthathu ekulawuleni okubalulekile nemingcele yokuvikela kanye Nephutha LeSoftware-Implemented. Ukubekezelelana (SIFT). Izinzwa zokulawula nokuvikela zibalulekile ngokuphindwe kathathu futhi zivotelwa yizo zontathu izicubunguli zokulawula. Izimpawu zokuphuma kwesistimu zivotelwa ezingeni lokuxhumana lama-solenoid abalulekile, ezingeni lengqondo lemiphumela yokuxhumana esele kanye namavalvu e-servo ekhoyili amathathu wamasignali okulawula i-analogi, ngaleyo ndlela kukhulisa ukwethembeka kokubili kokuvikela nokugijima. Imojula yokuvikela ezimele ihlinzeka ngokutholwa kwentambo eqinile ngokuphindwe kathathu kanye nokuvalwa kwesivinini esingaphezulu kanye nokubona ilangabi. Le mojula iphinde ivumelanise ijeneretha ye-turbine ohlelweni lwamandla. Ukuvumelanisa kusekelwa umsebenzi wokuhlola kumaphrosesa okulawula amathathu.

I-Mark V Control System yakhelwe ukufeza zonke izidingo zokulawula i-gas turbine. Lokhu kufaka phakathi ukulawula uketshezi, igesi noma kokubili okuphehla ugesi ngokuhambisana nezidingo zejubane, ukulawulwa komthwalo ngaphansi kwezimo zengxenye yomthwalo, ukulawulwa kwezinga lokushisa ngaphansi kwezimo eziphezulu zamandla noma phakathi nezimo zokuqalisa. Ngaphezu kwalokho, ama-vane omhlahlandlela we-inlet kanye nomjovo wamanzi noma umusi kulawulwa ukuze kuhlangatshezwane nekhabhoni kanye nezidingo zokusebenza. Uma isilawuli esikhishwayo sisebenzisa amasu e-Dry Low NOx, isiteji sikaphethiloli nemodi yokusha kulawulwa uhlelo luka-Mark V, oluphinde luqaphe inqubo. Ukulandelana kwezinsiza ukuze kuvunyelwe ukuqalisa okuzenzakalelayo, ukuvala shaqa kanye nokupholisa phansi nakho kusingathwa yi-Mark V Control System. Ukuvikelwa kweturbine ezimeni zokusebenza ezimbi kanye nokumenyezelwa kwezimo ezingavamile kufakwa ohlelweni oluyisisekelo.

Isixhumi esibonakalayo somsebenzisi siqukethe isiqaphi sesithombe esinemibala kanye nekhibhodi ukunikeza impendulo mayelana nezimo zokusebenza zamanje. Imiyalo yokokufaka evela ku-opharetha ifakwa kusetshenziswa idivayisi yokubeka ikhesa. Ukulandelana kwengalo/exe-cute kusetshenziselwa ukuvimbela ukusebenza okungaqondile kwe-tur-bine. Ukuxhumana phakathi kwesixhumi esibonakalayo somsebenzisi kanye nokulawula i-turbine kunge-Common Data Processor, noma , kumaphrosesa amathathu okulawula abizwa , futhi . I-interface yomsebenzisi iphinde isingathe i-com-
imisebenzi yomculo enamadivayisi akude nangaphandle. Ukuhlelwa kokuzithandela, kusetshenziswa isixhumi esibonakalayo somsebenzisi esingafuneki, kuyatholakala kulezo zinhlelo zokusebenza lapho ubuqotho besixhumanisi sedatha yangaphandle bubhekwa bubalulekile ekusebenzeni kwezitshalo okuqhubekayo. Ubuchwepheshe be-SIFT buvikela ekuhlulekeni kwemojula nokusabalalisa amaphutha edatha. Ukuboniswa kwe-opharetha okufakwe isipele okufakwe kwiphaneli, okuxhunywe ngokuqondile kuzinqubo zokulawula, kuvumela ukuqhubeka nokusebenza kwe-turbine yegesi esimweni esilindelekile sokwehluleka ukusebenzelana komsebenzisi okuyinhloko noma imojula.

Ukuxilongwa okwakhelwe ngaphakathi kwezinhloso zokuxazulula inkinga kubanzi futhi kufaka phakathi "ukwenyusa amandla," ingemuva kanye nezinqubo zokuxilonga eziqalwe mathupha ezikwazi ukuhlonza kokubili amaphutha ephaneli yokulawula namaphutha enzwa. Lawa maphutha akhonjwa phansi kuze kufike ezingeni lebhodi lephaneli kanye nezinga lesekhethi yenzwa noma izingxenye ze-actuator. Amandla okushintsha amabhodi aku-inthanethi akhelwe kumklamo wephaneli futhi
itholakalela lezo zinzwa ze-turbine lapho ukufinyelela ngokomzimba nokuhlukaniswa kwesistimu kungenzeka. Setha
amaphuzu, amapharamitha wokushuna kanye nezilinganiso zokulawula ziyalungiseka ngesikhathi sokusebenza kusetshenziswa isibambiso
isistimu yephasiwedi ukuvimbela ukufinyelela okungagunyaziwe.

I-DS200CTBAGIA ibhodi yokunqamula i-GE Common Data Processor. Ine-Ma.input kanye ne-Ma. okukhiphayo.DS200CTBAG1A ifakwe kubhodi ye-TBQA futhi inesixhumi esingu-9 pin RS232 sokuxilongwa kwe-TIMN . I-DS200CTBAG1A inezixhumanisi ezimbili zokuxhumana, isixhumanisi esisodwa se-IONET kanye nesesibili sephrosesa ye-ARCNET.
