Amakuru yibanze yabakoresha
Isosiyete ikora amarembo ya valve ikora cyane cyane ibicuruzwa bya valve.Ibikoresho by’uruganda rukora ibicuruzwa bikubiyemo itanura rya toni 2 ziciriritse zikoreshwa mu ziko, zikoreshwa na kVA 2000 (10KV / 0,75 kVA) sisitemu yo gutanga amashanyarazi yabigize umwuga.Ibikoresho bifite akabati 2 y’indishyi zifite ubushobozi bwa 600 kVA, itanura ya toni 1 intera itandukanya induction, 800 kVA (10KV / 0.4KV) ihinduranya tekinike n’umwuga, hamwe n’inama y’indishyi ya capacitance ifite ubunini bwa 300 kVA.Igishushanyo cya sisitemu yo gutanga amashanyarazi niki gikurikira:
Amakuru yimikorere
Imbaraga zigaragara zikozwe mumashanyarazi aringaniye zifite ibikoresho bya transformateur ya 2000KVA ni 700KVA-2100KVA, imbaraga zikora ni P = 280KW-1930KW, umutwaro udasanzwe ni Q = 687KAR-830KAR, ibintu byingufu ni PF = 0.4-0.92, na ikigezweho gikoraⅰ = 538 A-1660 A, imbaraga zigaragara z itanura ryigihe gito ryinjizwamo rifite 800KVA transformateur ni 200KVA-836KVA.Imbaraga zikora ni P = 60KW-750KW, umutwaro wogukora ni Q = 190KAR-360KAR, ingufu ni PF = 0.3-0.9, hamwe numuyoboro wakazi i = 288 A-1200 A. Kuberako inama yindishyi ya capacitor idashobora gushyirwaho mubikorwa (indishyi zikora zirananirana, iyo capacitori ikoreshwa nintoki, urusaku rwa capacitori ntirisanzwe, ingendo zumuzunguruko, capacitor irapakirwa, amavuta yamenetse, yamenetse, kandi ntashobora gukoreshwa), imbaraga zuzuye zukwezi Ikintu ni PF = 0,78, kandi inyungu yinguzanyo ya buri kwezi ihindurwa hejuru ya 32.000.
Isesengura rya Sisitemu Yimbaraga
Umutwaro nyamukuru wumuriro wo hagati wumuriro w'amashanyarazi ukosora amashanyarazi ni 6-gukosora.Ibikoresho bikosora bihindura AC muri DC mugihe bibyara umubare munini wubwuzuzanye.Inkomoko isanzwe ihuza imiyoboro ihujwe muri gride, kandi impedance ya gride itanga voltage ya garmonique, itera voltage ya grid Kugoreka kugoreka bigira ingaruka kumiterere yumuriro wamashanyarazi numutekano wibikorwa, byongera igihombo cyumurongo hamwe n’umuriro wa voltage, kandi byongera ingufu.Iyo banki yububasha bwa reaction ya banki ishyizwe mubikorwa, kubera ko imiterere iranga inzitizi ya banki ya capacitor ari nto, ihuza ryinshi ryinjizwa muri banki ya capacitor, kandi ingano ya capacitive current Kwiyongera byihuse bigira ingaruka zikomeye mubuzima bwa serivisi.Ku rundi ruhande, iyo reaction ya capacitif ya reaction ya banki ya capacitor ihwanye na reaction ya harmonic inductive reaction ya sisitemu hanyuma hagakurikiraho rezanse ikurikirana, imiyoboro ihuza iraguka cyane (inshuro 2-10), bikaviramo ubushyuhe bukabije no kwangirika ubushobozi.Byongeye kandi, guhuza bizatera DC sinusoidal umuraba guhinduka, bikavamo umuhengeri wimisozi, byoroshye gutera gusohora igice mubikoresho bikingira.Gusohora igihe kirekire igice nacyo bizihutisha gusaza kwibikoresho byangiza kandi byoroshye kwangiza capacitor.Kubera iyo mpamvu, ubushobozi bwa capacitori yindishyi zinama ntizishobora gukoreshwa kugirango hishyurwe itanura ryigihe gito, kandi hagomba gutoranywa ibikoresho byunganira amashanyarazi hamwe nibikorwa byo guhagarika pulse.
Gahunda yo kuvura indishyi zifatika
Intego z'imiyoborere
Igishushanyo cyibikoresho byindishyi zujuje ibyangombwa bisabwa byo guhagarika guhuza no gucunga ingufu zidasanzwe.
Muburyo bwimikorere ya sisitemu 0.75KV na 0.4KV, nyuma yuko ibikoresho byindishyi zungururwa bimaze gukoreshwa, umuyoboro wa pulse urahagarikwa, kandi impuzandengo yingufu zingana buri kwezi zirenga 0.95.Iyinjiza rya filteri yindishyi ntizitera pulse ya resonance ya resonance cyangwa resonance birenze urugero.

Ukurikije imiterere yihariye yikigo, isosiyete yacu yateguye urutonde rurambuye rwigihe gito rwinjizwamo itanura ritera amashanyarazi amashanyarazi.Suzuma neza ibintu bitwara imizigo hamwe no guhagarika guhuza, hanyuma ushyireho urutonde rwumubyigano muke wamashanyarazi yungurura amashanyarazi kumurongo wo hasi wa voltage ya sosiyete 0.75KV na 0.4KV kugirango uhindure imiterere, wishyure ingufu zidasanzwe, kandi utezimbere imbaraga.Mugihe cyo gukora itanura ryigihe giciriritse, igikoresho cyo gukosora kibyara 6K + 1, kandi urukurikirane rwa Fourier rukoreshwa mu kubora no guhindura imiyoboro kugirango habeho guhuza 5 bya 250HZ na 7 bihuza hejuru ya 350HZ.Kubwibyo, mugihe hateguwe akayunguruzo indishyi zidafite akamaro z itanura ryumurongo, hagomba kwemezwa ko umuzunguruko wamashanyarazi ishami ryumuzunguruko wishyura ingufu zidakora muguhagarika neza imiterere yumurongo uri hejuru ya 250HZ na 350HZ, kandi byongera imbaraga zingufu.
umukoro
Imbaraga zuzuye za toni 2 hagati ya feri ya induction ya induction ihuye na transformateur ya kVA 2000 yishyurwa kuva 0.78 kugeza kuri 0.95.Igikoresho cyo kuyungurura akayunguruzo kigomba kuba gifite ubushobozi bwa 820 kVA, kandi igahita ihinduka mumatsinda 6 yubushobozi, buri kimwe kikaba gihuye nu kuzenguruka kuruhande rwa voltage yo hepfo ya transformateur kugirango indishyi.Ubushobozi bwo gutondekanya ibyiciro ni 60KVAR, ishobora kuzuza ibisabwa bitandukanye byingufu zikoreshwa mumatara yo hagati.Ikintu cyuzuye cyingufu za toni 1 intera itandukanya intera yinjizwamo ihuye na 800 kVA transformateur yishyurwa kuva 0.78 kugeza kuri 0.95.Ibikoresho by'indishyi byungururwa bigomba kuba bifite ubushobozi bwa 360 kVA, bishobora guhita bihindurwa mumatsinda 6 yubushobozi, naho ubushobozi bwo guhinduranya amanota ni 50 kVA, bushobora kuzuza ingufu zinyuranye zisabwa n’itanura ryinjira hagati.Ubu bwoko bwibishushanyo byemeza neza ko imbaraga zahinduwe zirenze 0.95.
