Ijambo ryibanze: Imbaraga twahawe na sisitemu ya gride sisitemu akenshi iringaniza.Mubisanzwe, mugihe cyose voltage igarukira mugihe cyagenwe, turashobora kubona ibidukikije byiza byo gukoresha amashanyarazi.Ariko sisitemu yo gutanga amashanyarazi ntabwo itanga amashanyarazi meza.Byongeye kandi, nta kuntu abakora ibikoresho batanga ibikoresho birinda kugabanuka kumashanyarazi kubikoresho byose byamashanyarazi.Ikibazo cya voltage sag kizatera ibibazo byinshi nibibazo mubuzima bwa buri munsi numusaruro.Nibihe bikoresho byiza byindishyi bihari kugirango bigabanye ingaruka za voltage sags?Mubisanzwe, dukoresha ubwoko butatu bwibikoresho byindishyi: UPS (Amashanyarazi adahagarara), Solid State Transfer Switch (SSTS), na Dynamic Voltage Restorer (DVR - Dynamic Voltage Restorer).Mugushira ibyo bikoresho byindishyi hagati ya sisitemu yo gutanga amashanyarazi numuyoboro wamashanyarazi.Ibi bikoresho bitatu byindishyi bifite inyungu zabyo nibibi.
Amashanyarazi adahagarikwa (UPS - Amashanyarazi adahagarikwa): UPS mugihe gito, nigikoresho gikoreshwa cyane mukugabanya indishyi za voltage sag.Ihame ryakazi rya UPS mubisanzwe ni ugukoresha ingufu za chimique nka bateri kugirango ubike ingufu zamashanyarazi.Iyo uhuye nikibazo cyo kunanirwa gutunguranye kwa sisitemu yo gutanga amashanyarazi, UPS irashobora gukoresha ingufu zabitswe mbere kugirango ibungabunge amashanyarazi muminota mike kugeza kumasaha menshi.Muri ubu buryo, ikibazo cya voltage sag cyatewe na sisitemu yo gutanga amashanyarazi kirashobora gukemurwa mugihe runaka.Ariko UPS nayo ifite intege nke zayo zigaragara.Amashanyarazi abikwa binyuze mumashanyarazi, kandi iki gishushanyo ubwacyo gitwara ingufu nyinshi.Batteri zibika ingufu ntabwo zifata umwanya munini gusa, ariko kandi biragoye kubungabunga.Mugihe kimwe, kuri iyo mitwaro igira ingaruka zikomeye kuri gride, birakenewe kongera imbaraga zayo.Bitabaye ibyo, biroroshye gutera bateri yo kubika ingufu kunanirwa.
Guhindura uburyo bukomeye bwo kwimura leta (SSTS - Guhindura Leta ikomeye), byitwa SSTS.Mubikorwa byinganda zikora inganda cyangwa gukoresha amashanyarazi nyayo kubakoresha.Mubusanzwe hariho bisi ebyiri zitandukanye cyangwa imirongo itanga amashanyarazi kuva mumashanyarazi atandukanye yo gutanga amashanyarazi.Muri iki gihe, iyo umurongo umwe utanga amashanyarazi ufite interineti cyangwa guhagarara kwa voltage, birashobora kwihuta (5-12m) guhindurwa mukindi cyuma gikoresha amashanyarazi ukoresheje SSTS, bityo bigatuma umurongo wose utanga amashanyarazi ukomeza.Kugaragara kwa SSTS bigamije igisubizo cya UPS.Ntabwo igiciro rusange cyibikoresho bishora imari ari gito, ariko kandi nigisubizo cyiza kumanuka wa voltage yimitwaro myinshi.Ugereranije na UPS, SSTS nayo ifite ibyiza byinshi nkigiciro gito, ikirenge gito, hamwe no kubungabunga-ubusa.Gusa ikibi ni uko busbar ya kabiri cyangwa imirongo yinganda ziva mubice bitandukanye bisabwa kugirango amashanyarazi atangwe, ni ukuvuga ko amashanyarazi asubizwa inyuma.
Dynamic Voltage Restorer (DVR - Dynamic Voltage Restorer), yitwa DVR.Mubisanzwe, bizashyirwaho hagati yo gutanga amashanyarazi nibikoresho byo gutwara.DVR irashobora kwishura uruhande rwumutwaro kuri voltage ikwiye muri milisegonda, kugarura uruhande rwumutwaro kuri voltage isanzwe, no gukuraho ingaruka za voltage sag.Igikorwa cyingenzi cya DVR nugutanga byihuse umwanya wo gusubiza, kandi birashobora kandi kongera ubujyakuzimu bwa voltage sag kurinda.Ubujyakuzimu bwo kurinda bushobora gusobanurwa nkurwego rwa voltage sag DVR ishobora kwakira.Cyane cyane kubakoresha uruganda, mubisanzwe, iyo habaye ihindagurika rya voltage sag mugihe gikora gisanzwe cyimashini nibikoresho, bizoroha byoroshye ikibazo mubipimo byatsinze umusaruro, ni ukuvuga ko hazabaho ibicuruzwa bifite inenge.Ukoresheje DVR, ibisabwa bisanzwe mubikorwa byuruganda birashobora kwizerwa, kandi imvururu ziterwa nihindagurika ryumuvuduko muke ntirishobora kumvikana.Ariko DVR ntabwo ifite uburyo bwo kwishyura ihungabana rya voltage irenze ubujyakuzimu bwa voltage sag.Kubwibyo, mugihe igitonyanga cya voltage kiri murwego rwuburebure bwa voltage sag kurinda, DVR irashobora kugira uruhare rwayo mugihe byemejwe ko idahagarara.
DVR yakozwe na Hongyan Electric ifite uburyo bwizewe bushoboka: kwizerwa cyane, kugenewe cyane cyane imitwaro yinganda, imikorere ya sisitemu yo hejuru, igisubizo cyihuse, imikorere ikosora neza, nta gutera inshinge, tekinoroji yuzuye yo kugenzura imibare ishingiye kuri DSP, imikorere yizewe, kwaguka bigereranijwe imikorere, igishushanyo mbonera, imikorere-yimikorere myinshi hamwe nigishushanyo mbonera cya TFT cyerekana amabara, kwerekana neza-kubusa, kugiciro gito cyo gukora, ntagikeneye ibikoresho byo gukonjesha, igishushanyo mbonera cyimiterere, ikirenge gito nibindi byiza byinshi.
