Chidziwitso chofananira cha jenereta (2)

Ndi chiyani chomwe chiyenera kuzindikiridwa pamene quasi-synchronized parallelling of jenereta zosonkhanitsira?
Kuyanjana kwa Quasi-simultaneous ndi njira yothandiza.Kaya ntchitoyo ndi yosalala kapena ayi ali ndi mgwirizano wabwino ndi wogwiritsa ntchito.Pofuna kupewa kuyanjana nthawi zosiyanasiyana, kutsatira mikhalidwe itatu sikuloledwa kutseka.
1. Pamene nsonga ya tebulo yolumikizira idumpha, sikuloledwa kutseka, chifukwa chakuti pangakhale kumverera kwa tepi mkati mwa tebulo logwirizanitsa, lomwe silingasonyeze zovuta zofanana.
2. Pamene tebulo nthawi imodzi imatembenuka mofulumira, zimasonyeza kuti kusiyana kwafupipafupi pakati pa jenereta yomwe yawerengedwa kuti ifanane ndi yamitundu yosiyanasiyana ya jenereta ndi yaikulu.Chifukwa chakuti nthawi yotseka ya wophwanya dera ndizovuta kuzindikira, wodutsa dera nthawi zambiri samatsekedwa pamalo olumikizirana.Osaloledwa kutseka.
3. Ngati nsonga ya tebulo yolumikizira imayima pamalo ophatikizira, sikuloledwa kutseka chosinthiracho ikasiya.Izi zili choncho chifukwa ngati mafupipafupi a imodzi mwa jenereta amakhazikitsa kusintha mwadzidzidzi panthawi yotseka yopuma, ndizotheka kuti wosweka atseke pa chinthu chosagwirizanitsa.
4. Momwe mungasinthire kumveka kwamphamvu kwa m'mbuyo kwa makina ofananira?
Pamene 2 jenereta seti ndi juxtaposed popanda matani, padzakhala vuto la pafupipafupi kusiyana komanso voteji kusiyana pakati pa magulu awiri jenereta.Ndipo pazida zowunikira (ammeter, mita yamagetsi, mita yamagetsi) pamakina onsewa, mawonekedwe enieni amagetsi amawonekera, imodzi ndi mphamvu yakumbuyo yomwe imayamba chifukwa cha liwiro losakhazikika (nthawi zonse), ndipo inayo imayambitsidwa ndi kusiyana kwamagetsi. .Ntchito yosinthidwa, kusinthidwa kwake kumayenderana ndi:

1. Kusintha kwa zochitika za mphamvu zowonongeka zomwe zimayambitsidwa ndi mafupipafupi: ngati maulendo a machitidwe awiriwa sali ofanana, komanso kusiyana kwake kuli kwakukulu, kudzawonetsedwa pa chida (ammeter, mita yamagetsi), panopa chipangizo chothamanga kwambiri chimasonyeza mtengo wabwino, komanso mita yamagetsi imasonyeza mtengo wabwino.Mphamvu, kumbali ina, yomwe ilipo ikuwonetsa kufunikira koyipa, komanso mphamvu ikuwonetsa kufunikira koyipa.Pakalipano, sinthani mlingo (mafupipafupi) a imodzi mwa mayunitsi, ndikusintha molingana ndi chizindikiro cha mita ya mphamvu, ndikusintha chizindikiro cha mita ya mphamvu kuti ayi.Pangani zisonyezo zamphamvu za mayunitsi onse ayi, kuti mitengo yozungulira (nthawi zonse) ya zida zonse ziwiri ikhale yofanana.Komabe, pamene ammeter ikuwonetsabe pakali pano, ichi ndi chodabwitsa champhamvu chomwe chimayambitsidwa ndi kusiyana kwa magetsi.
2. Kusintha kwa chodabwitsa cha reverse mphamvu chomwe chimayambitsidwa ndi kusiyana kwa voteji: pamene zizindikiro za mita yamagetsi zamagulu awiri a jenereta zilibe ayi, ndipo ammeter akadali ndi chizindikiro chamakono (ndiko kuti, chopindika chimodzi ndi chizindikiro chimodzi chabwino), voteji. Kusintha pakati pa ma jenereta kungathe kusinthidwa.Mukasintha konoko, zimatengera chizindikiritso cha ammeter komanso mawonekedwe amphamvu.Chotsani chizindikiro cha ammeter (ndiko kuti, sinthani kuti ayi).Pambuyo pa ammeter ilibe chizindikiro, sinthani mphamvuyo kukhala yokulirapo kuposa 0.5 kutengera chizindikiro cha mita yamagetsi.Nthawi zambiri, imatha kusinthidwa kukhala pafupifupi 0.8, yomwe ili yabwino kwambiri.
5. Jenereta chitetezo dera
1. Mphamvu yobwerera kumbuyo Kumverera kwamphamvu kwapambuyo kumadza chifukwa cha kusiyana kwa mlingo (nthawi zonse) komanso voteji ya chosonkhanitsa cha jenereta, ndiko kuti, chopereka chimodzi cha jenereta chimakhala ndi mphamvu zabwino, pamene zosonkhanitsa zina zosiyanasiyana zimakhala ndi mphamvu zoipa.Ndiko kunena kuti, dongosolo lokhala ndi mphamvu zowonongeka limakhala matani pakalipano (mafupipafupi a dongosolo lino ndi otsika ndipo mlingo wozungulira sukugwirizana).Pamene ma voltages sali ofanana, makina omwe ali ndi voteji yapamwamba amapereka mphamvu yowonjezera komanso yowonjezera magetsi ku chipangizocho ndi mphamvu yochepa (ammeter ya unityi imasonyeza njira yabwino), zomwe zimawonjezera gawo lolamulira gawo mu dongosolo lamagetsi.Chigawo chokhala ndi voteji chochepa chimatha kukhala chochuluka kwambiri panthawiyi, kupeza mphamvu yowonjezera yowonjezera kuti ikhale yofanana ndi mayunitsi awiriwa (ammeter ya dongosololi imasonyeza komwe akubwerera).Mukayang'anitsitsa, sinthani mphamvu yamagetsi amtundu wina waukulu kapena kuchepetsa mphamvu yamagetsi amtundu wina, zomwe zimapangitsa kuti chipangizocho chikhale ndi mphamvu yosinthira yomwe ilipo, komanso momwe ikugwirira ntchito ikukhudzana ndi 20% ya zomwe zilipo.Kubwereranso kwamagetsi kumathamanga, maulendo, komanso ma alarm, komabe sikusiya.
2. Zowonjezera: Mphamvu yovotera ya seti ya jenereta yapano ndiyotsimikizika, ndipo kuchuluka kwake kochulukira kumakhala kotsika kwambiri, makamaka ponena za 5% ya mphamvu zosankhidwa.Nthawi yololedwa yolemetsa ndi 15 ~ 30 mphindi, komanso kuchuluka kwake sikuposa 60 min.Seti ya jenereta idzatenthedwa, komanso kutsekemera kwa zingwe kudzachepetsedwa, zomwe zidzachepetsa moyo wautumiki.Pachifukwa ichi, ngati palibe chosowa chapadera pakukhazikitsa chitetezo chowonjezereka, chitetezo cha overcurrent chikhoza kukhazikitsidwa pa 110% pakali pano.Pamayeso onse onyamula katundu, bweretsani zomwe zilipo ku 110% yazomwe zidavotera pano, komanso kubwezeredwa mopitilira muyeso kudzachitapo kanthu.Ulendo, alamu, palibe kutseka.
3. Kuchulukirachulukira: Pamene ma seti a jenereta agwiritsidwa ntchito mofanana, chimodzi mwamantha kwambiri ndi chakuti makina opangira magetsi adzagwedezeka.Mwamsanga pamene voteji ya oscillating dongosolo kuwonjezeka, n'zosavuta kuyambitsa kutchinjiriza kusweka kwa zida magetsi komanso zipangizo magetsi, ndi zipangizo magetsi komanso zida magetsi adzakhala immobilized wina ndi mzake.Pazifukwa izi, ma seti a jenereta omwe amagwiritsidwa ntchito limodzi ali ndi chitetezo chochulukirapo, komanso mtengo wake wokhazikitsidwa ndi 105% wamagetsi ovotera ndiwothandiza kwambiri.Short-circuit over-voltage relay, ulendo komanso kusiya, ma alarm.
