Amakuru yibanze yabakoresha
Uruganda rukora ibicuruzwa bya pulasitike rukora cyane cyane imiyoboro itanga amazi ya PE, imiyoboro yo kuvoma ibyuma, nibindi. Isosiyete ifite imirongo 4 yumusaruro, igice cyingufu zitwara moteri ikoresha moteri ya DC idafite amashanyarazi na moteri ya DC ihindagurika, hariho ibice bine bya 400KVA, buri transformateur uruhande rwo hasi rwumuvuduko rufite ibikoresho byindishyi.Igishushanyo cya sisitemu yo gutanga amashanyarazi niki gikurikira:
Amakuru yimikorere
Moteri ya DC ya transformateur ya 400KVA, imbaraga nyinshi za inverter ni 360KW, impuzandengo yingufu ni PF = 0.7, amashanyarazi akora ni 780A, agasanduku k'indishyi zitemewe munsi ya buri transformateur akunze kugenda, capacitor iraguka kandi iratemba, kandi umugenzuzi ntashobora kugenzura ibintu bidasanzwe, nibindi. Phenomena, igipimo cyuzuye ni 0.8 gusa, naho ihazabu itemewe ni 15,000 kumwezi.Mubyongeyeho, moteri na yoroshye itangira kumurongo wibyara rimwe na rimwe byangiritse, bigira ingaruka kumusaruro.
Isesengura rya Sisitemu Yimbaraga
Umutwaro nyamukuru wa moteri ya DC itagira amashanyarazi na inverter ikosora amashanyarazi ni 6 amashanyarazi amwe.Mugihe cyo gukora ibikoresho bikosora, AC irashobora guhindurwa muri DC, igakora umubare munini wimpanuka ziva mumashanyarazi, ikazana imiyoboro ihuza amashanyarazi, kandi ikagira ingaruka kumashanyarazi.Inzitizi iranga itera imbaraga zumuriro wumuriro wa pulse, bikavamo hanze-yumurongo wumuriro wamashanyarazi nuwumuriro, bikabangamira ubwiza nibikorwa byumutekano woguhindura amashanyarazi, kongera umurongo wumurongo no gutandukana kwakazi, no kugira Ingaruka mbi kuri gride yamashanyarazi nibikoresho byamashanyarazi byuruganda rwamashanyarazi ubwarwo.
Porogaramu igenzura porogaramu ya mudasobwa (PLC) yunvikana kugoreka guhuza imbaraga za voltage yumurimo wo gutanga amashanyarazi.Mubisanzwe biteganijwe ko igiteranyo cyimikorere yimikorere ya voltage ikorwa (THD) iri munsi ya 5%, hamwe na pulse kugiti cyumubyigano wakazi Niba igipimo cyikigero kiri hejuru cyane, ikosa ryimikorere ya sisitemu yo kugenzura rishobora gutuma habaho ihagarikwa rya umusaruro cyangwa imikorere, bikaviramo impanuka nini yumusaruro.
Iyo banki yububasha bwa reaction yamashanyarazi ishyizwe mubikorwa, kubera ko impanuka ya pulse ihari iranga imbogamizi ya banki ya capacitor iba nto, umubare munini wimpanuka winjizwa mubice bigize capacitor, kandi amafaranga ariyongera cyane, bigira ingaruka zikomeye mubuzima bwa serivisi .Ku rundi ruhande, iyo ubushobozi bwa pulse ya capacitor ya banki ya capacitor ihwanye na inductor ihwanye na inductor ya software ya software, kwiyongera kwimyuka ihuza (inshuro 2-10) bizatera capacitor gushyuha no kuyisenya, kandi pulse igezweho izatera inshuro zimbaraga zisohoka guhinduka.Imiterere ya sinusoidal ntabwo iri murwego, bikavamo amenyo ameze nk'ay'amenyo ameze nk'umuhengeri, kandi bizatera gusohora igice cy'ibikoresho byiziritse, bityo byihutishe kwinjiza ibintu byiziritse, kandi byangiza ubushobozi bwa capacitor.Kubera iyo mpamvu, ubushobozi bwa capacitori yububasha bwimbaraga ntishobora gukoreshwa mumashanyarazi ya DC itagira amashanyarazi hamwe nindishyi zamashanyarazi, kandi hagomba gutoranywa akayunguruzo gafite imbaraga zo guhagarika amashanyarazi.
Shungura gahunda yo kuvura amashanyarazi
Intego z'imiyoborere
Igishushanyo cyibikoresho byindishyi zujuje ibyangombwa bisabwa byo guhagarika guhuza no gucunga ingufu zidasanzwe.
Munsi ya 0.4KV ya sisitemu yo gukora, nyuma yo kuyungurura ibikoresho byindishyi zashyizwe mubikorwa, impanuka ya pulse irahagarikwa, kandi impuzandengo yingufu zingana buri kwezi ni 0.92.
Urwego rwohejuru ruhuza resonance, resonance overvoltage, hamwe na overcurrent iterwa no guhuza na filteri yindishyi zishami ntizizabaho.

Gutegura ibitekerezo
Ukurikije imiterere yihariye yikigo, isosiyete yacu yateguye urutonde rwa moteri ya DC irambuye kandi yoroshye yo gutangiza amashanyarazi yishyurwa.Tekereza neza kubintu bitwara imizigo no guhagarika guhuza, hanyuma ushyire muyunguruzi kuruhande rwa 0.4KV hepfo yumubyigano wa transformateur wikigo kugirango uhindurwe n’amashanyarazi make kugirango uhagarike imikoranire, wishyure ingufu zidasanzwe, kandi utezimbere ingufu.Mugihe cyo gukora moteri ya DC na inverter, igikoresho cyo gukosora kibyara 6K + 1 ihuza cyane.Nyuma yubu ibora kandi ihindurwa nuruhererekane rwa Fourier, inshuro 5 za 250HZ ninshuro 7 zihuza hejuru ya 350HZ.Kubwibyo, mugushushanya hagati yumuriro wumuriro w'amashanyarazi muyungurura amashanyarazi yingirakamaro, birakenewe gushushanya imirongo ya 250HZ, 350HZ no hejuru kugirango harebwe niba ishami ryindishyi ziyungurura rishobora guhagarika neza imiterere mugihe ryishyura ingufu zidasanzwe kandi zitezimbere ingufu.
umukoro
Imbaraga zuzuye za moteri ya DC numuyoboro uhindura umurongo uhuye na 400KVA transformateur yishyurwa kuva 0.7 kugeza hejuru ya 0.95.Akayunguruzo kayunguruzo kagomba gushyirwaho kubushobozi bwa 380kvar, igabanijwemo amatsinda 4 yubushobozi hanyuma igahita icibwa kugirango yishyure kugoreka kuruhande rwa voltage ntoya ya transformateur.Ubushobozi bwo guhinduranya ibyiciro ni 45kvar, bushobora Guhuza ningufu zinyuranye zisabwa kumurongo wibyakozwe, igishushanyo rero cyemeza neza ko imbaraga zahinduwe ziri hejuru ya 0.9.
Isesengura ryingirakamaro nyuma yo kwishyiriraho indishyi
Muri Nyakanga 2010, hashyizweho akayunguruzo k'ingufu zishyurwa ingufu za moteri ya DC na moteri zihindura kandi zishyirwa mubikorwa.Igikoresho gihita gikurikirana impinduka zumutwaro wa moteri ya DC hamwe nabahinduranya inshuro nyinshi, ikabuza guhuza-murwego rwohejuru mugihe nyacyo, ikishyura imbaraga zidasanzwe, kandi igateza imbere imbaraga.ibisobanuro nkibi bikurikira:
Nyuma yo gushungura ibikoresho byungururwa bimaze gukoreshwa, imbaraga zimpinduka zumurongo nyuma yo gushungura ibikoresho byungururwa bimaze gukoreshwa ni 0.99 (igice cyazamutse ni 0.7 mugihe ibikoresho byindishyi byakuweho)
Imikorere
Kugeza ubu ikoreshwa na transformateur ya 400KVA yagabanutse kuva kuri 770A igera kuri 520A, igabanuka rya 33%.Nyuma yindishyi, kugabanya igihombo cyamashanyarazi ni WT = △ Pd * (S1 / S2) 2 * τ * [1- (cosφ1 / cosφ2) 2] = 5 × {(0.7 × 400) 400} 2 × 0.4≈2.8 ( kw · h) Muri formula, Pd nigihombo gito cyumuzunguruko wa transformateur, ni 5KW, kandi kuzigama buri mwaka amafaranga yumuriro ni 2.8 * 20 * 30 * 10 * 0.7 = 11.700 yuan (ukurikije gukora amasaha 20 a umunsi, iminsi 30 mukwezi, amezi 10 kumwaka, kuri kwh amashanyarazi 0.7 yuan).
ibintu byimbaraga
Muri rusange uburenganzira bw’isosiyete bwiyongereye kuva kuri 0.7 bugera kuri 0.95, uburenganzira bw’ukwezi bwagumye kuri 0.96-0.98, naho ibihano byiyongera kuva ku 15.000 ku kwezi bigera ku 3.000-5000 ku kwezi.
Moteri ya BLDC kandi yoroshye yo kuyungurura
Igikoresho cyo kwishyura amashanyarazi gikora gifite ubushobozi bwo guhagarika impanuka ya pulse no kwishyura imitwaro yingufu zidasanzwe, gukemura ikibazo cyibihano byamashanyarazi, kongera umusaruro wa transformateur, kugabanya ingufu zikoreshwa, no kongera umusaruro, bizana inyungu zigaragara mubukungu kuri sosiyete no kugaruka kwishoramari ryumushinga wumwaka ushize.Kubwibyo, isosiyete yishimiye cyane indishyi zingufu za moteri ya DC idafite amashanyarazi na filteri ya inverter, kandi izamenyekanisha abakiriya bamwe mugihe kizaza.
