Kugabanya ingufu z'amashanyarazi no kuzigabanya: Hasobanuwe ingamba zitandukanye zo kurwanya impinduka mu mikorere y'amashanyarazi

Intangiriro: Ingufu zirwanya gusubira inyuma ntabwo ari kimwe no kuzimya imirasire y'izuba

Uko imiyoboro y'izuba ikoreshwa mu mazu no mu bucuruzi buto ikomeza kwiyongera,kugenzura urujya n'uruza rw'amashanyarazi rudasubira inyumaByabaye ngombwa cyane mu turere twinshi. Abakora imiyoboro y'amashanyarazi bagenda bagabanya cyangwa babuza ingufu zirenze urugero za photovoltaic (PV) koherezwa mu miyoboro rusange y'amashanyarazi, bigatuma abashushanya sisitemu bahitamo icyo bitakurwanya gusubira inyuma or nta kohereza mu mahangaibisubizo.

Ariko, hari ukutumvikana gusanzwe kugaragara:
Gukoresha ingufu zirwanya gusubira inyuma ntibisobanura guhagarika burundu ikoreshwa ry'izuba.

Mu by'ukuri, hariingamba nyinshi za tekinikikugenzura urujya n'uruza rw'amashanyarazi inyuma, buri kimwe gifite imiterere itandukanye ya sisitemu, imyitwarire yo gusubiza, n'ibisabwa mu bikoresho. Gusobanukirwa izi tandukaniro ni ingenzi mu guhitamo igisubizo gikwiye ku mushinga runaka wa PV.

Iyi nkuru isobanura iby'ingenziingamba zo kurwanya urujya n'uruza rw'amashanyarazi, igereranyanta kohereza mu mahanganaimipaka y'ingufu zihinduka, kandi isobanura nezaiyo icyuma gipima ingufu gikoresheje ubwenge kiba ingenzimu murongo w'ubuyobozi.

Kohereza hanze ibintu byose mu mirasire y'izuba ni iki?

Kohereza ntaho bihuriye n'ibyoherejweyerekeza ku ngamba zo kugenzura ahoNta ngufu zirenze zemerewe kuva kuri sisitemu ya PV zisubira kuri gridIngufu zose zikomoka ku bimera zigomba gukoreshwa mu gace runaka cyangwa zikagabanywa.

Muri configuration ya zero-kohereza ibicuruzwa mu mahanga:

• Ingufu zikoreshwa mu gukwirakwiza amashanyarazi aho ihuriro rihurira (PCC) ziguma kuri zeru cyangwa hafi ya zeru

• Umusaruro wa PV uragabanuka iyo ikoreshwa ry'amashanyarazi rigabanutse

• Ingufu zijyanwa hanze zirakumirwa cyane aho kugabanyirizwa gusa

Ubu buryo bukunze gukoreshwa mu turere aho ibigo bibuza gukoresha grid cyangwa aho ibiciro byo kwinjira mu ruganda bitaboneka.

Kugabanya imbaraga zikoresha imbaraga ni iki?

Ingufu zihinduka(byitwa kandi kugenzura ibicuruzwa bihinduka) ni ingamba yoroshye kandi yoroshye. Aho gushyira mu bikorwa amabwiriza akomeye yo kohereza ibicuruzwa mu mahanga igihe cyose, sisitemuihora ihindura umusaruro wa PV hashingiwe ku bipimo by'ingufu za grid mu gihe nyacyo.

Ibintu by'ingenzi biranga umuntu birimo:

• Umusaruro wa PV ukurikiza ihindagurika ry'imitwaro mu buryo bugaragara

• Amafaranga make yo kohereza mu mahanga ashobora kwemerwa cyangwa gukurwaho uko bikenewe

• Igisubizo cyihuse ku mpinduka z'umutwaro ugereranije n'imipaka idahinduka

Uburyo bwo kugenzura ibintu bukwiriye cyane cyane sisitemu za PV zo mu rugo zifite imizigo ihindagurika, ububiko bw'ingufu, cyangwa chargers za EV.

Zero Export vs Dynamic Power Limitting: Itandukaniro ry'ingenzi

Iri gereranya rigaragaza itandukaniro rikomeye:
kugenzura ingufu zihinduka bisaba ibitekerezo mu gihe nyacyo, mu gihe sisitemu z'ibanze zo kohereza hanze zishobora kwishingikiriza ku miterere ya inverter idahinduka.

Ni iyihe ngamba yo kurwanya gusubira inyuma isaba igipimo cy'ingufu?

Aha niho imiterere myinshi ya sisitemu inanirwa.

Kohereza hanze hashingiwe kuri Inverter (Hadakoreshejwe Metero yo hanze)

Inverters zimwe na zimwe zishyigikira imirimo yo kohereza hanze y’igihugu hakoreshejwe:

• Uburyo bwo gutahura umuriro bwubatswemo

• Imipaka y'ingufu zidahinduka

Nubwo byoroshye, ibi bisubizo akenshi bikunze kugaragaramo ibibazo bikurikira:

• Igihe cyo gusubiza gitinze

• Ubuziranenge buke mu gihe cy'impinduka zihuse ku mutwaro

• Kudashobora kwihuza n'ahantu hafite imizigo myinshi

Bashobora gukorera mu buryo buhamye ariko bakaba bagorwa no gukoresha amazu mu buryo busanzwe.

Impamvu igenzura ry'ingufu zikoresha imbaraga risaba igipimo cy'ingufu gisobanutse

In kugenzura ingufu zihinduka, Gutanga ibitekerezo ku ngufu za grid mu buryo bwihuse bivuye kuri smart energy meter ni ingenzi.

Hatabayeho gupima neza kandi mu buryo nyabwo aho umurongo uhurira, sisitemu yo kugenzura ntishobora kumenya:

• Niba ingufu z'amashanyarazi zitumizwa mu mahanga cyangwa zijyanwa mu mahanga

• Uburyo umusaruro wa PV ugomba guhindurwa vuba

• Niba imipaka yo kohereza ibicuruzwa mu mahanga irenga mu bihe by'agateganyo

Igipimo cy'ingufu gikoresha ubwenge gitanga:

• Gupima buri gihe ibicuruzwa byinjizwa mu mahanga/byoherezwa mu mahanga

• Amakuru y'ingufu afite ubushobozi bwo hejuru

• Ikimenyetso cyizewe cyo kugenzura inverter cyangwa EMS logic

Uruhare rwa PC321 ya Owon mu kugenzura imikorere y'amashanyarazi arwanya gusubira inyuma

Mu buryo bukoresha imbaraga zirwanya gusubira inyuma kw'ingufu,Igipimo cy'ingufu cya PC321 gikoresha ingufu zigezweho ikora nk'ukourwego rwo kumenya mu gihe nyacyoaho ikoranabuhanga rihurira.

By'umwihariko, PC321:

• Ipima ingufu z'amashanyarazi mu buryo bw'igihe nyacyo (kwinjiza no kohereza mu mahanga) muri PCC

• Itanga ibitekerezo byihuse bikwiriye imiyoboro ikoresha uburyo bwo kugenzura ibintu

• IbishyigikirwaWiFi, MQTT, na Zigbeeamahitamo y'itumanaho

• Ifasha sisitemu zo kugenzura gusubiza muriIngendo zo guhindura mu masegonda abiri, byujuje ibisabwa bisanzwe byo kugenzura PV zo mu mazu

Mu gutanga amakuru y’ingufu z’amashanyarazi nyayo kandi ku gihe, PC321 yemerera inverters cyangwasisitemu zo gucunga ingufu to kugenzura buri gihe umusaruro wa PV, gukumira urujya n'uruza rw'amashanyarazi rusubira inyuma nta gufunga ikoreshwa ry'amashanyarazi bitari ngombwa.

Icy'ingenzi ni uko PC321 idakora igenzura ubwayo—ikorabifasha kugenzura binyuze mu gutanga ibipimo byizewe, ari na ryo shingiro ry'ingamba zose zikora zo kugabanya imbaraga zihinduka.

Guhitamo ingamba zikwiye zo kurwanya gusubira inyuma

Guhitamo igisubizo gikwiye cyo kurwanya gusubira inyuma biterwa n'ibintu byinshi:

• Amabwiriza agenga grid zo mu gace n'amategeko agenga kohereza ibicuruzwa mu mahanga

• Ihindagurika ry'imizigo n'uburyo ikoreshwa mu ngo

• Kuba hari ububiko bw'ingufu cyangwa amashanyarazi akoreshwa mu ikoranabuhanga

• Umuvuduko ukenewe wo gusubiza n'ubuhanga bwa sisitemu

Ku bijyanye n'uburyo bworoshye bwo kubahiriza amategeko, kohereza ibicuruzwa mu mahanga hifashishijwe inverter bishobora kuba bihagije.
Ku bijyanye na sisitemu za PV zigezweho zo guturamo zifite imizigo ihindagurika,Igenzura ry'ingufu zikoresha ikoranabuhanga rikoresha ikoranabuhanga ritanga imikorere myiza n'ikoreshwa ry'ingufu.

Umwanzuro: Gutembera k'amashanyarazi mu buryo bunyuranyije n'amategeko ni ingamba zo kugenzura, si uguhagarika

Ingufu zinyura mu buryo bunyuranyije n'amategeko ntizisobanura ko zihagarika ikoreshwa ry'izuba. Ahubwo, zigaragazafilozofiya yo kugenzura—kuringaniza umusaruro wa PV n'ikoreshwa ry'amashanyarazi mu gihe nyacyo n'imbogamizi za grid.

Gusobanukirwa itandukaniro riri hagati yanta kohereza mu mahanganaimipaka y'ingufu zihindukabifasha abashushanya sisitemu kwirinda gushyiramo ibintu mu buryo budakora neza no guhitamo inyubako zitanga ubuziranenge n'imikorere myiza.

Uko sisitemu za PV zigenda zirushaho kuba abanyabwenge kandi zihuzwa,gupima mu gihe nyacyo kuri grid interface—bikoresheje ibyuma bipima ingufu by’ubwenge—byabaye ikintu cy’ibanze gisabwaku buryo bugezweho bwo kugenzura imikorere y'amashanyarazi arwanya gusubira inyuma.
