Incazelo
Uchungechunge lwe-9905/9907 lwe-Woodward 2301A lulawula ukwabelana komthwalo nesivinini samajeneretha ashayelwa izinjini zikadizili noma zikaphethiloli, noma izinjini zesitimu noma zegesi. Le mithombo yamandla kubhekiselwa kuyo “njengabahambisi abakhulu” kulo lonke leli bhukwana.
Isilawuli sifakwe ku-chassis ye-sheet-metal futhi siqukethe ibhodi lesifunda elilodwa eliphrintiwe. Wonke ama-potentiometers afinyeleleka kusukela ngaphambili kwe-chassis.
I-2301A inikeza ukulawula kumodi ye-isochronous noma ye-droop.
Imodi ye-isochronous isetshenziselwa isivinini esiqhubekayo sokunyakaza nge:
Ukusebenza kwe-single-prime-mover;
Izihambisi eziyinhloko ezimbili noma ngaphezulu ezilawulwa amasistimu okulawula ukwabelana komthwalo we-Woodward ebhasini elingalodwa;
Ukulayisha okuyisisekelo ngokumelene nebhasi elingapheli elinomthwalo olawulwa yi-Automatic Power Transfer and Load (APTL) Control, Isilawuli Sokungenisa/Ukuthekelisa, Isilawuli Sokulayisha I-Generator, Isilawuli Senqubo, noma enye insiza elawula ukulayisha.
I-droop mode isetshenziselwa ukulawula isivinini njengomsebenzi wokulayisha nge:
Ukusebenza kwe-Single-prime-mover ebhasini elingapheli noma
Ukusebenza okuhambisanayo kwabanyakazi ababili noma ngaphezulu abaphambili.
Okulandelayo isibonelo sezingxenyekazi zekhompuyutha ezijwayelekile ezidingekayo kuhlelo lwe-2301A olulawula i-prime-mover eyodwa kanye nejeneretha:
Ukulawulwa kwe-elekthronikhi kwe-2301A
Umthombo wamandla wangaphandle wama-Vdc angama-20 kuye kwangama-40 wamamodeli ane-voltage ephansi; 90 kuya ku-150 Vdc noma 88 kuya ku-132 Vac kumamodeli anamandla kagesi
I-actuator elinganayo yokubeka idivayisi ye-fuel-metering, kanye
Ama-transformer amanje futhi angaba khona okulinganisa umthwalo othwelwe i-generator.

Izinhlelo zokusebenza
Izilawuli ze-elekthronikhi ze-2301A 9905/9907 zinebanga lejubane elishintshekayo. Noma yimaphi kulawa mamodeli okulawula angasethwa ukuthi asebenze phakathi kwebanga lesivinini elilinganiselwe elilandelayo:
500 ukuze 1500 Hz
1000 ukuze 3000 Hz
2000 ukuze 6000 Hz
4000 ukuze 12 000 Hz

Lezi zilawuli zitholakalela izinhlelo zokusebenza eziyisa phambili noma ezibuyisela emuva, futhi zingasetshenziswa nezicuphi ze-actuator eyodwa noma ze-tandem. Amamodeli obubanzi bamanje be-actuator ayatholakala, kanye nemodeli yamandla kagesi aphezulu (90 kuya ku-150 Vdc noma 88 kuya ku-132 Vac, 45 kuya ku-440 Hz), kanye nemodeli yamandla aphansi (20 kuya ku-40 Vdc). Imodeli yamandla kagesi aphezulu ibonakala injalo ngaphambili; imodeli ye-voltage ephansi ayikho.
Kumasistimu asebenza ngokuhlehlayo, i-actuator ibiza uphethiloli owengeziwe lapho i-voltage ye-actuator yehla. Ukulahlekelwa okuphelele kwamandla kagesi ku-actuator kuzoshayela i-actuator kuphethiloli ogcwele. Lokhu kuvumela umbusi we-ballhead oyikhophi yasenqolobaneni ukuthi alawule esikhundleni sokuvala isiguquli esiyinhloko njengoba bekungenza uhlelo olusebenza ngokuqondile.
Irempu yokunciphisa oyikhethayo nayo inikezwa. Uma le nketho ikhona, isikhathi sokukhuphuka usuka esivinini esilinganiselwe uye esivinini esingasho lutho cishe imizuzwana engama-20. Uma le nketho ingekho, lokhu kwenzeka ngokushesha.
Amathebula 1-1 kanye no-1-2 abonisa izinombolo zengxenye nezici zazo zonke 9905/9907 uchungechunge 2301A ukwabelana komthwalo nezilawuli zesivinini.

I-2301A Full Authority Speed ​​Control isetha isivinini noma umthwalo wenjini kadizili, injini yegesi, i-steam turbine, noma i-gas turbine ngokuya ngesidingo senqubo noma isignali yokulawula ikhompuyutha engu-4–20 mA noma 1–5 Vdc.
