KUSINTHA KWA HARDWARE

SPEEDTRONIC ™ Mark V gas control turbine system idapangidwira makamaka ma GE gasi ndi ma turbines a nthunzi, ndipo imagwiritsa ntchito tchipisi tambiri ta CMOS ndi VLSI zosankhidwa kuti achepetse kutayika kwamagetsi ndikukulitsa magwiridwe antchito. Mapangidwe atsopanowa amataya mphamvu zochepa kuposa mibadwo yam'mbuyo pamapanelo ofanana. Mpweya wozungulira wolowera m'malo olowera uyenera kukhala pakati pa 32 F ndi 72 F (0 C ndi 40 C) ndi chinyezi chapakati pa 5 ndi 95%, osasunthika. Gulu lokhazikika ndi gulu la NEMA 1A lomwe ndi lalitali mainchesi 90, mainchesi 54 m'lifupi, mainchesi 20 kuya, ndipo limalemera pafupifupi mapaundi 1,200. Chithunzi 11 chikuwonetsa gulu lomwe zitseko zotsekedwa.

Kwa ma turbine a gasi, gulu lokhazikika limayenda pa 125 volt DC unit batri mphamvu, ndi AC chothandizira pa 120 volt, 50/60 Hz, yogwiritsidwa ntchito poyatsira thiransifoma ndipurosesa. Gulu lodziwika bwino lidzafunika ma watts 900 a DC ndi ma watts 300 amphamvu y AC. Kapenanso, mphamvu yothandizira ikhoza kukhala 240 volt AC 50 Hz, kapena ikhoza kuperekedwa kuchokera ku inverter yakuda yoyambira kuchokera ku batri.

Gawo logawa mphamvu limayang'anira mphamvu ndikuzigawira kwa magetsi omwe ali ndi mapurosesa osafunikira kudzera m'mafusi osinthika. Gawo lililonse lowongolera limapereka mabasi ake oyendetsedwa ndi DC kudzera pa otembenuza a AC/DC. Izi zitha kuvomereza ma DC osiyanasiyana omwe akubwera, omwe amapangitsa kuwongolera kulekerera kwamphamvu kwamagetsi amagetsi a batri, monga omwe amayamba chifukwa choyambitsa injini ya dizilo. Magwero onse amagetsi ndi mabasi oyendetsedwa amawunikidwa. Mphamvu zamagetsi pawokha zitha kusinthidwa pomwe turbine ikugwira ntchito.

Interface Data processor, makamaka yakutali, ikhoza kuyendetsedwa ndi mphamvu yapakhomo. Izi zitha kukhala choncho ngati chipinda chapakati chowongolera chili ndi dongosolo la Uninterruptible Power Supply (UPS). AC kwa am'deralopurosesa nthawi zambiri imaperekedwa kudzera pa chingwe chochokera ku gulu la SPEEDTRONIC™ Mark V kapenanso kuchokera kumagetsi apanyumba. Chipindacho chimapangidwa modular ndipo chimakhala chokhazikika. Chithunzi cha mkati mwa gululi chikuwonetsedwa mu Chithunzi 12, ndipo ma modules amadziwika ndi malo omwe ali mu Chithunzi 13. Iliyonse mwa ma moduleswa imakhalanso yokhazikika, ndipo gawo la purosesa likuwonetsedwa mu Chithunzi 14. makadi akhoza kupezeka aliyense payekha.

Makhadi amalumikizidwa ndi zingwe zokhala ndi riboni kutsogolo zomwe zimatha kulumikizidwa mosavuta kuti zigwiritsidwe ntchito. Kupendeketsa choyikapo khadi m'malo mwake ndikutseka chivundikiro chakutsogolo kumatseka makhadiwo.

Lingaliro lalikulu laperekedwa pakuwongolera mawaya omwe akubwera kuti achepetse phokoso ndi ma crosstalk. Wiring wapangidwa kuti azitha kupezeka mosavuta kuti aziyika mosavuta. Waya uliwonse umadziwika mosavuta ndipo kuyika kwake ndikwabwino.

KUGWIRITSA NTCHITO ZOCHITA
Zamagetsi
• Ikulumikiza ku purosesa wamba "C" I/O
• Amalamula kuwongolera kwa turbine
- Kuyambitsa / kuyimitsa kwa turbine
- Kuthamanga kwa Turbine
- Bwanamkubwa adakhazikitsa mfundo yokweza / kutsitsa
- Kusankha koyambira / kokwera kwambiri
- Kusankha mafuta a gasi / Distillate
- Magetsi a jenereta (VARS) kwezani / kutsitsa
- Kulunzanitsa kwa jenereta kuletsa / kutulutsa
• Ndemanga kuchokera ku turbine control
- Watts, VARS ndi ma volts (analogi yamamita)
- Wophwanya udindo
- Kuyambira mndandanda
- Chizindikiro cha moto
- Pa chizindikiro chowongolera kutentha
• Kuwongolera ma alarm
- Kutumiza kwa data kwa RS232C kokha, kuchokera ku <1>
Ulalo wa Modbus
• turbine control ndi Modbus akapolo station
• Kutumiza popempha ndi master, 300 mpaka 19,200
mdani
• Imalumikizana ndi purosesa ya mawonekedwe (I)
• RS232C wosanjikiza ulalo
• Malamulo omwe alipo
- Malamulo onse ovomerezeka akutali alipo
- Kuwongolera ma alarm
• Ndemanga kuchokera ku turbine control
- Zambiri zamtundu wa turbine zomwe zimapezeka mu I data base
