Uruganda rwa peteroli

Amakuru yibanze yabakoresha
Uruganda rwa peteroli rukora cyane cyane ibicuruzwa bya gaze.Ibikoresho by'amashanyarazi bikoreshwa nisosiyete ni umutwaro woroheje utwara umushoferi, kandi impinduka yo gukwirakwiza ni 2500 kVA.Igishushanyo cya sisitemu yo gutanga amashanyarazi niki gikurikira:

Amakuru yimikorere
Imbaraga zose zihindura imirongo ya 2500KVA ihindura ni 1860KVA, impuzandengo yingufu ni PF = 0.8, naho ikora ni 2400-2700A.

Isesengura rya Sisitemu Yimbaraga
Urufunguzo rwo gutanga amashanyarazi ni umutwaro wa rectifier inverter itanga amashanyarazi, ikaba ari umutwaro wa sisitemu yihariye.Ibikoresho bibyara byinshi bihuza mugihe cyibikorwa, nisoko isanzwe ihuza.Umuyoboro uhuza amashanyarazi winjizwa mumashanyarazi bizatera imbaraga zumurimo woguhuza kumurongo wikiranga wumuriro wamashanyarazi, bikavamo ihindagurika ryumuriro wumurimo numuyoboro wamashanyarazi, bikabangamira ubuziranenge numutekano wa sisitemu yo gutanga amashanyarazi, bikongera gutakaza umurongo no gukora ikosa rya voltage, no guteza ibyangiritse bikomeye kumashanyarazi ninganda zitunganya.Ibikoresho byayo byamashanyarazi, cyane cyane abaministre basanzwe bishyura ingufu bizatera ingaruka mbi, kandi biroroshye gutera guhindagurika, bitera kwangiza ibikoresho byamashanyarazi nkakabati ka capacitor.Kubwibyo, imbaraga nke zidafite imbaraga zo kwishura amashanyarazi hamwe nibikorwa byo guhagarika ibikorwa bigomba gutoranywa kugirango uhagarike sisitemu ihuza, yishyure imitwaro ikora, kandi itezimbere imbaraga.

Shungura gahunda yo kuvura amashanyarazi
Intego z'imiyoborere
Akayunguruzo k'indishyi zashizweho kugirango zuzuze ibisabwa kugira ngo zihagarike guhuza imbaraga nimbaraga zidasanzwe.
Muburyo bwa 0.4KV ya sisitemu yo gukora, nyuma yo kuyungurura ibikoresho byo kuyungurura biva mu ruganda, guhagarika guhuza biri hejuru ya 0,92 ku kigereranyo cy’ingufu za buri kwezi.

Ntugateze guhuza resonance cyangwa resonance birenze urugero kandi birenze kubera ishami ryindishyi zishungura.

Gutegura ibitekerezo
Ukurikije uko ibintu byifashe mu ruganda, isosiyete yacu irareba byimazeyo ibintu bitwara imizigo hamwe no guhagarika guhuza muyungurura indishyi zitemewe za inverter, ikanashyiraho akayunguruzo k’indishyi katemewe kuri 0.4KV y’umuvuduko ukabije w’impinduramatwara, guhagarika guhuza no kwishyura indinganizo yo kongera imbaraga zidasanzwe.imbaraga.
Mugihe cyimikorere ya frequency frequency, izabyara inshuro 5 za 250HZ, inshuro 7 za 350HZ nibindi bihuza-murwego rwo hejuru.Kubwibyo, mugihe utegura akayunguruzo indishyi zidafite ingaruka za inverter, hagomba kwemezwa ko umuzunguruko wishami ryindishyi zumuzunguruko zishobora guhagarika neza guhuza no kwishyura ingufu zidakoreshwa kumirongo iri hejuru ya 250HZ na 350HZ kugirango itezimbere ingufu.

umukoro
Impamvu zuzuye zingufu zumurongo wogutanga amashanyarazi wahujwe na buri 2500 kVA transformateur yishyurwa kuva 0.8 kugeza kuri 0.92.Ibikoresho byo kwishura ibikoresho bigomba gushyirwaho bifite ubushobozi bwa 900 kWt.Ubushobozi bwamatsinda 11 yo kugabana ibice byahujwe no guhinduranya kumurongo wo hasi wa voltage kuruhande rwa transformateur kugirango ihuze kandi ihagarike byikora.Ubushobozi bwo gutondekanya ibyiciro ni 45KVAR, bushobora kuzuza ibisabwa bitandukanye byingufu zoroshye zitangira n'imirongo ikora.Ubu bwoko bwibishushanyo byemeza neza ko imbaraga zahinduwe zirenze 0.95.

Isesengura ryingirakamaro nyuma yo kwishyiriraho indishyi
Muri kamena 2011, hashyizweho igikoresho cyo kwishyura amashanyarazi inverter filter itanga ingufu.Igikoresho gihita gikurikirana impinduka zumutwaro wa inverter, ihita ihagarika urwego rwohejuru rwimikorere ya pulse kugirango yishyure imitwaro itagaragara, kandi itezimbere imbaraga.ibisobanuro nkibi bikurikira:

Nyuma yo gushungura ibikoresho byungururwa bimaze gukoreshwa, imbaraga zo guhindura umurongo zingana na 0,98 (igice cyazamutse ni 0.8 mugihe igikoresho cyo kwishyura cyayungurujwe)

Imikorere
Imikorere ikora ya transformateur ya 2500KVA yagabanutse kuva 2700A igera kuri 2300A, naho kugabanuka ni 15%.Nyuma yindishyi, kugabanya ingufu zamashanyarazi ni WT = △ Pd * (S1 / S2) 2 * τ * [1- (cosφ1 / cosφ2) 2] = 24 × {(0.85 × 2000) / 2000} 2 × 0.4≈16 . amasaha kumunsi, iminsi 30 mukwezi, namezi 10 kumwaka, 0.7 yuan kuri kilowati).

ibintu byimbaraga
Muri uku kwezi ibintu by’ingufu by’isosiyete byiyongereye kuva kuri 0.8 bigera kuri 0.95 muri uku kwezi, kandi ingufu zizakomeza kuri 0.96-0.98 mu kwezi gutaha, kandi ibihembo biziyongeraho 5000-6000 Yuan muri Mutarama.
Muri rusange, amashanyarazi make ya voltage yingufu zoroheje zitangira filteri ifite ubushobozi bwiza cyane bwo guhagarika imiyoboro ya pulse no kwishyura ingufu zidasanzwe, gukemura ikibazo cyibihano bitanga ingufu byikigo, kongera umusaruro wa transformateur, no kugabanya imbaraga zikora Ibicuruzwa byongeweho ibicuruzwa byongereye umusaruro, bizana inyungu zigaragara mubukungu muri sosiyete, kandi byagaruye ishoramari ryabakiriya mugihe cyumwaka umwe.Kubwibyo, yoroshye ya filteri yoroheje itangiza amashanyarazi yakozwe nisosiyete irashimishije cyane, kandi izakurura abakiriya benshi mugihe kizaza.
