Mu buryo bugezweho bw'ingufu n'ibikoresho by'ikoranabuhanga, ibikoresho birinda ingufu (SPDs) na inverters, nk'ibice bibiri by'ingenzi, imikoranire yabyo ni ingenzi mu gutuma sisitemu yose ikora neza kandi mu mutekano. Bitewe n'iterambere ryihuse ry'ingufu zishobora kuvugururwa no gukoreshwa cyane kw'ibikoresho by'amashanyarazi, ikoreshwa ry'ibi byombi ryarushijeho kuba risanzwe. Iyi nkuru izasuzuma amahame y'imikorere, ibipimo ngenderwaho byo guhitamo, uburyo bwo gushyiraho SPDs na inverters, ndetse n'uburyo zishobora guhuzwa neza kugira ngo zitange uburinzi bwuzuye ku buryo bw'ingufu.

Mu buryo bw'amashanyarazi bugezweho, ibikoresho bikingira umuvuduko (SPD) bigira uruhare runini. Haba mu ngo, mu nganda, mu bigo by'amakuru cyangwa mu bigo by'itumanaho, SPD zishobora kurinda neza ingufu z'amashanyarazi ziterwa n'inkuba, ihindagurika ry'umuyoboro w'amashanyarazi n'ibindi bintu, bigatuma ibikoresho bikoreshwa neza. Iyi nkuru izagaragaza ibisobanuro birambuye, ihame ry'imikorere, uburyo bwo guhitamo n'ubuyobozi bwo gushyiraho SPDs, kandi ikavuga ku kamaro kayo mu manza zifatika. Byongeye kandi, tuzanasesengura ingaruka zikomeye zishobora kubaho iyo nta SPD ihari.

Mu 2024, igihombo cy’ubukungu cyatewe n’inkuba ku isi yose cyageze kuri miliyari 4.7 z’amadolari y’Amerika, hafi 60% by’ibi bihombo byatewe no kudakingira neza sisitemu z’amashanyarazi. Nk’igikoresho cy’ingenzi cyo kurwanya kwiyongera k’amashanyarazi, ubwiza bw’ibikoresho birinda kwiyongera k’amashanyarazi (SPDs) bugena neza uburyo sisitemu yose y’amashanyarazi ikora. Iyi nkuru izasuzuma amabanga yo gushyiraho iyi "power guard", ikuyobore mu gisubizo cyuzuye kuva ku mahame kugeza ku ishyirwa mu bikorwa mu buryo bufatika.

Ubushobozi bwa fotovoltaic ku isi bwarenze 350GW umwaka ushize, aho Ubushinwa bwatanze inkunga irenga kimwe cya gatatu. Iri koranabuhanga rikoresha ibidukikije rihindura imirasire y'izuba amashanyarazi ryagabanutseho 80% mu myaka icumi ishize, ariko rihura n'ikibazo gikomeye cy'inkuba - sitasiyo y'amashanyarazi yo muri Arizona, muri Leta Zunze Ubumwe za Amerika, yigeze gutakaza miliyoni 2 z'amadolari kubera inkuba. Ibyuma bikingira amashanyarazi byabaye "ikintu gikiza ubuzima" cy'ibigo by'amashanyarazi, biyobora volti ibihumbi mirongo by'amashanyarazi y'inkuba mu butaka binyuze mu muyoboro w'uburinzi bw'urwego rutatu. Impuguke mu nganda zagaragaje ko uko ingufu za sisitemu za photovoltaic zizamuka zikagera kuri 1500V, ibikoresho byo kurinda birimo gutangiza impinduramatwara mu ikoranabuhanga mu bikoresho bya silikoni.

Kuva ku gushyiraho kugeza ku kubungabunga, ibi bisobanuro ntibigomba kwirengagizwa

Mu buryo bwa none bw'amashanyarazi, ibikoresho bikingira ingufu (SPD) ni nk'"ubwishingizi" ku bikoresho by'ikoranabuhanga. Ariko se wari ubizi? Iki gikoresho gisa n'icyoroshye, iyo gishyizwemo cyangwa kidakoreshejwe neza, ntikibasha gutanga uburinzi gusa ahubwo gishobora no guteza akaga mu mutekano. Uyu munsi, reka tuvuge ku ngaruka n'ingaruka zo gukoresha SPD.

Kubera ko ubushobozi bwa fotovoltaic ku isi burenze ikimenyetso cya 1TW, ibibazo by’ubwirinzi n’umutekano bya sisitemu birimo kwiyongera. Dukurikije imibare iheruka yavuye muri Komite Mpuzamahanga ya Tekiniki ya TC82 (IEC), ibibazo by’amashanyarazi byangiritse bigira uruhare runini mu mikorere no kubungabunga sitasiyo z’amashanyarazi za fotovoltaic, aho ibyangiritse mu bikoresho byatewe no gushyuha kw’amashanyarazi mu gihe gito bingana na 28.7% by’ibyangiritse byose. Iki kibazo ni ingenzi cyane mu turere dushyuha n’utwo mu turere dushyuha dufite inkuba nyinshi.

Bitewe n’iterambere ryihuse ry’inganda zikora ingufu zikomoka ku mirasire y’izuba ku isi, umutekano n’ituze bya sisitemu zitanga ingufu z’izuba byabaye ikintu cy’ingenzi mu nganda. Sisitemu zikomoka ku mirasire y’izuba zigaragara hanze igihe kirekire kandi zishobora guhura n’ibibazo nk’inkuba, ihindagurika ry’imiyoboro y’amashanyarazi, ndetse n’ibura ry’ibikoresho, bishobora kwangiza ibikoresho cyangwa ndetse no gutwika. Ibikoresho birinda umuvuduko w’amashanyarazi (SPDs), ibica uruziga, na fuse ni ibikoresho by’ingenzi birinda buri kimwe mu bikorwa byacyo kandi bigakorana kugira ngo sisitemu ikore neza. Iyi nkuru izasesengura byimbitse imikorere yabyo, uburyo bwo guhuza ibikorwa, n’ibikenewe kugira ngo haboneke ishingiro ku bakoresha inganda.

Kuki ibikoresho byawe bikenera "Voltage Bodyguard"?

Tekereza ibi: Mu ijoro ry'inkubi y'umuyaga, imirabyo inyura mu kirere, ibikoresho byawe bifite agaciro k'ibihumbi amagana "bihita bigwa." Iyi si inkuru yo muri filime iteye ubwoba ahubwo ni inzozi mbi z'inganda nyinshi n'imiryango byahuye nazo. Igikoresho cyo kurinda umuvuduko w'amashanyarazi (SPD) ni cyo "gihangange" cy'iyi nkuru—gishobora gukumira umuvuduko w'amashanyarazi uteje akaga mu isegonda rimwe gusa. Ariko dore ikibazo: abantu benshi bazana uyu "murinzi" mu rugo batazi uburyo bwo kuwukoresha neza.

Uyu munsi, reka tuvuge kuri uyu mucungamutungo usa n'aho woroshye ariko ugoye cyane w'umutekano w'amashanyarazi.

Muri iki gihe gishingiye ku ikoranabuhanga, ibikoresho by'amashanyarazi n'iby'ikoranabuhanga biri mu kaga gakomeye kurusha mbere hose ko kwangirika kw'amashanyarazi guterwa n'inkuba, ihindagurika ry'imiyoboro y'amashanyarazi, cyangwa ibikorwa byo guhinduranya imbere mu kirere. Ibikoresho bikingira ingufu, bizwi kandi nka ibikoresho bikingira ingufu (SPDs), bigira uruhare runini mu kurinda ibikoresho byoroheje imbaraga z'amashanyarazi. Iyi nkuru irasuzuma uburyo ibikoresho bikingira ingufu mu nganda zitandukanye kandi ikagaragaza imikorere yabyo binyuze mu bushakashatsi.

Intangiriro

Ibikingira by’ubushyuhe (SPDs) ni ingenzi mu buryo bw’amashanyarazi mu kugabanya ubushyuhe bw’igihe gito no gukumira ubushyuhe bw’amashanyarazi. Bikoreshwa cyane haba muri sisitemu y’amashanyarazi agororotse (DC) ndetse no muri sisitemu y’ubushyuhe busimburana (AC). Bitewe n’imiterere itandukanye y’ibikingira by’ubushyuhe bya DC n’ibikingira by’ubushyuhe bya AC, ibikingira by’ubushyuhe byabyo nabyo bitandukanye cyane mu miterere, imikorere, n’uburyo bikoreshwa. Iyi nkuru izasesengura isano n’itandukaniro riri hagati y’ibikingira by’ubushyuhe bya DC n’ibikingira by’ubushyuhe bya AC mu buryo burambuye, kandi itange inama zo guhitamo.
