MPPT vs. PWM: Ni iyihe controller ibereye urumuri rw'umuhondo rumurika ku mirasire y'izuba?

Mu rwego rwo gukemura ibibazo by'izuba,amatara y'umuhondo amurika ku zubaByabaye igice cy'ingenzi mu bikorwa bitandukanye birimo gucunga ibinyabiziga, aho bwubatsi, n'ibimenyetso byihutirwa. Nk'umucuruzi w'inararibonye w'amatara y'umuhondo amurika ku mirasire y'izuba, Qixiang asobanukiwe akamaro ko guhitamo imashini iyobora amashanyarazi ikwiye kugira ngo yoroshye imikorere y'aya matara. Hari ubwoko bubiri bw'ingenzi bw'imashini ziyobora amashanyarazi zikoreshwa mu mirasire y'izuba: Maximum Power Point Tracking (MPPT) na Pulse Width Modulation (PWM). Iyi nkuru izasuzuma itandukaniro riri hagati y'imashini ziyobora MPPT na PWM kandi igufashe guhitamo imashini iyobora amashanyarazi ikwiriye ibyo ukeneye mu itara ry'umuhondo rimurika ku mirasire y'izuba.

Menya ibijyanye n'ibikoresho bikoresha ingufu z'izuba

Mbere yo kwibanda ku kugereranya, ni ngombwa gusobanukirwa icyo icyuma gipima ingufu z'izuba gikora. Ibi bikoresho bigenzura ingufu z'amashanyarazi n'amashanyarazi kuva ku mirasire y'izuba kugera kuri bateri, bigatuma bateri ishaje neza kandi mu mutekano. Guhitamo icyuma gipima ingufu bishobora kugira ingaruka zikomeye ku mikorere no kuramba kwa sisitemu yawe y'urumuri rw'umuhondo rumurika.

Abagenzuzi ba PWM

Udukoresho two kugenzura ubugari bwa pulse width modulation (PWM) ni two dukoresho two kugenzura imirasire y'izuba. Dukora duhuza agace k'izuba na bateri kandi tugakoresha urukurikirane rw'ibimenyetso byo guhinduranya kugira ngo tugenzure uburyo bwo gusharija. Ubugari bw'ikimenyetso "kuri" buhinduka hashingiwe ku miterere ya bateri, bigatuma habaho uburyo bwo gusharija buhamye kandi bugenzurwa.

Ibyiza bya PWM Controllers:

1. Byoroshye kandi bihendutse:

Udukoresho twa PWM muri rusange turahendutse kandi tworoshye gushyiramo kurusha utundi dukoresho twa MPPT. Ibi bituma tuba amahitamo meza ku mishinga ikoresha amafaranga menshi.

2. Kwizerwa:

Bitewe n'ibice bike n'imiterere yoroshye, ibikoresho byo kugenzura PWM bikunze kuba byizewe cyane kandi ntibisaba ko bibungabungwa cyane.

3. Ingufu mu mikorere mito:

Ku mirasire y'izuba mito aho ingufu z'imirasire y'izuba zihuye neza n'amashanyarazi ya bateri, imikorere y'icyuma gipima PWM iba iri hejuru cyane.

Abagenzuzi ba MPPT

Ibikoresho bigenzura ingufu z'izuba (MPPT) ni ikoranabuhanga rigezweho rituma ingufu ziva mu mirasire y'izuba ziyongera. Bikurikirana buri gihe umusaruro w'ibikoresho bigenzura ingufu z'izuba kandi bigahindura aho amashanyarazi akorera kugira ngo hamenyekane ko ingufu nyinshi zisohoka.

Ibyiza bya MPPT Controller:

1. Ubushobozi bwo gukora neza cyane:

Ugereranije n’ibikoresho bigenzura imirasire y’izuba bya PWM, ibikoresho bigenzura imirasire y’izuba bya MPPT bishobora kongera imikorere ya sisitemu z’izuba kugeza kuri 30%, cyane cyane iyo ingufu z’imirasire y’izuba ziri hejuru y’imbaraga za batiri.

2. Imikorere myiza mu gihe cy'urumuri ruto:

Akamashini gapima MPPT gakora neza mu gihe hari urumuri ruto, bigatuma kaba keza cyane ku mirasire y'izuba y'umuhondo igomba gukora neza ndetse no mu minsi y'ibicu cyangwa nimugoroba.

3. Uburyo bworoshye bwo gushushanya sisitemu:

Ibikoresho bigenzura imirasire y'izuba bya MPPT bifasha mu buryo bworoshye gukoresha imirasire y'izuba ifite ingufu nyinshi, ibi bikaba bishobora kugabanya ikiguzi cy'insinga n'igihombo.

Ni iyihe controller ikwiriye gukoresha urumuri rw'umuhondo rw'izuba?

Mu guhitamo ibikoresho bigenzura imirasire ya MPPT na PWM ku mirasire y'izuba y'umuhondo, icyemezo gishingira ahanini ku bisabwa byihariye mu ikoreshwa ryawe.

- Ku mishinga mito kandi idafite ingengo y'imari: Niba urimo gukora ku mushinga muto ufite ingengo y'imari ntoya, PWM controller ishobora kuba ihagije. Ni nziza, ihendutse, kandi ishobora gutanga ingufu zihagije ku matara y'umuhondo akoresha imirasire y'izuba mu bihe byiza.

- Ku bikorwa bikomeye cyangwa bigoye cyane: Niba umushinga wawe ukeneye imikorere myiza, cyane cyane iyo urumuri ruhindutse, igenzura rya MPPT ni ryo rikwiye. Kongera imikorere no gukora neza mu bihe by'urumuri ruto bituma igenzura rya MPPT riba ryiza mu kwemeza ko amatara yawe y'umuhondo ahora akora neza.

Mu gusoza

Nk'umucuruzi w'amatara y'umuhondo yizewe akoresha imirasire y'izuba, Qixiang yiyemeje gutanga ibicuruzwa byiza n'ubuyobozi bw'inzobere kugira ngo bigufashe guhitamo neza imirasire y'izuba. Waba uhisemo PWM cyangwa MPPT controller, gusobanukirwa itandukaniro n'ibyiza bya buri kimwe bishobora gufasha guhitamo igisubizo gikwiye sisitemu yawe y'amatara y'umuhondo akoresha imirasire y'izuba.

Kubona ikiguzi cyihariye cyangwa ubundi bufasha mu guhitamo nezaitara ry'umuhondo ricana n'imashini igenzura imirasire y'izubaKu mushinga wawe, nyamuneka hamagara Qixiang. Turi hano kugira ngo tuguhe ibisubizo byizewe by'izuba kugira ngo bikumurikire!
