MPPT vs. pwm: Kodi ndi wolamulira uti wabwino kwambiri pachilankhulo cha dzuwa?

Mu gawo la zosintha za dzuwa,magetsi achikasu achikasuAkhala gawo lofunikira la ntchito zosiyanasiyana kuphatikizapo kasamalidwe kwamagalimoto, malo omanga, ndi zizindikilo zadzidzidzi. Monga wochitira chidwi ndi magetsi owala a dzuwa, Qixiang amamvetsetsa kufunika kosankha wowongolera zoyenera kuti athetse magetsi awa. Pali mitundu iwiri yayikulu ya owongolera solar yomwe imagwiritsidwa ntchito pogwiritsa ntchito ma solari: Kutulutsa kwakukulu kolowera (MPT) ndi mawonekedwe a pursetion (PWM). Nkhaniyi idzalowa mu kusiyana pakati pa olamulira pakati pa MPT ndi PWM ndikuthandizani kuti musankhe wowongolera ndi wabwino kwambiri pazosowa zanu zowoneka bwino.

Dziwani za olamulira a dzuwa

Asanayambe kuyerekezera, ndikofunikira kuti mumvetsetse kuti wolamulira wapamwamba kwambiri ndi uti. Zipangizozi zimayang'anira voliyumu ndi zamakono kuchokera ku madola a dzuwa ku batire, ndikuwonetsetsa kuti batire limalipitsidwa bwino komanso motetezeka. Kusankhidwa kwa Controble kungakhudze kwambiri magwiridwe antchito ndi kukhazikika kwa malo anu oyera oyera oyera.

Oyang'anira Pwm

Kusintha kwa ma purse kukula kwa ma pulse (mapm) olamulira ndi mtundu wachikhalidwe wa dzuwa. Amagwira ntchito polumikiza sitimayo mwachindunji ku batire ndikugwiritsa ntchito njira zingapo zosinthira kuti muchepetse njira yosungirako. M'lifupi mwake "pa" siginecha yosasintha chifukwa cha batire, kulola kuti pakhale njira yokhazikika komanso yolamulira.

Ubwino wa Olamulira a PWM:

1. Zosavuta komanso zotsika mtengo:

Oyang'anira pwm nthawi zambiri amakhala otsika mtengo komanso osavuta kukhazikitsidwa kuposa olamulira a MPTT. Izi zimawapangitsa kusankha kokongola kwa mapulojekiti opangira bajeti.

2. Kudalirika:

Chifukwa cha zigawo zochepa komanso mawonekedwe osavuta, olamulira a PWM amakonda kukhala odalirika ndipo amafuna kukonza zochepa.

3. Kuchita bwino m'magulu ang'onoang'ono:

Kwa makina ang'onoang'ono a solar pomwe magetsi a dzuwa amafanana kwambiri ndi magetsi a batri, mphamvu ya wowongolera pwm ndiyambiri kwambiri.

Olamulira a MPPT

Kutsata kwakukulu (MPTT) Olamulira ndiukadaulo wapamwamba kwambiri womwe umapangitsa mphamvu yomwe imatuta kuchokera ku manel a dzuwa. Amapitiliza kuwunika kutulutsa kwa dzuwa ndikusintha malo ogwiritsira ntchito zamagetsi kuti atsimikizire kuti mphamvu yayikulu imachotsedwa.

Ubwino wa Mppt:

1. Kuchita bwino:

Poyerekeza ndi olamulira a PWM, oyang'anira a MPT amatha kuwonjezera njira ya ma solar pofika 30%, makamaka pamene magetsi a dzuwa ndi okwera pachimake.

2. Kuchita bwino bwino pamavuto otsika:

Woyang'anira wa MPT amagwira bwino pamagetsi otsika, ndikupanga kukhala yabwino kuti ikhale yowoneka bwino kwambiri yachikasu yomwe ikufunika kugwira ntchito mokwanira ngakhale masiku amitambo.

3. Kusintha kwa dongosolo:

Olamulira a MPTT amalola kusinthasintha kwakukulu mu dongosolo kuti agwiritse ntchito magetsi apamwamba kwambiri, omwe amatha kuchepetsa mtengo ndi zotayika.

Ndi wolamulira uti yemwe ndi wabwino kwambiri kwa chikasu chowala?

Posankha olamulira a MPPT ndi PWM kuti ayandikire chikasu cha chikasu chowala, chisankhochi chimadalira kwambiri pazomwe mungagwiritse ntchito.

- Kwa ang'onoang'ono, okakamizidwa ndi bajeti: Ngati mukugwira ntchito yaying'ono yokhala ndi bajeti yocheperako, wowongolera pwm atha kukhala zokwanira. Ndiwodalirika, othandiza, ndipo amatha kupereka mphamvu zokwanira magetsi a dzuwa pansi pamagetsi okwanira.

- Zowonjezera kapena zowonjezera zowonjezera: Ngati ntchito yanu ikufuna kuchita bwino, makamaka mosintha magetsi, wolamulira wa MPT ndiye chisankho chabwino. Kuchulukitsa Kuchita bwino ndi magwiridwe antchito otsika kumapangitsa kuti oyang'anira a MPT awonetsetse kuti magetsi anu a dzuwa ndi omwe amayenda nthawi zonse amagwiritsa ntchito modalirika.

Pomaliza

Monga cholembera chilengedwe chowala chilengedwe, qixiang chimadzipereka kupereka zinthu zapamwamba komanso chitsogozo chaluso kuti akuthandizeni kupanga chisankho chabwino kwambiri. Kaya mumasankha wowongolera pwm kapena muyeso wa MPPT, kumvetsetsa kusiyana ndi maubwino amtundu uliwonse omwe angathandize kusankha yankho loyenera la dongosolo lanu lowala la dzuwa.

Pa mawu achinsinsi kapena thandizo lina posankha kumanjachikasu chilengedwe chakuwala ndi wolamuliraPa ntchito yanu, chonde khalani omasuka kulumikizana ndi Qixiang. Tili pano kuti ndikupatseni mwayi wothandiza pofuna kuyatsa njira yanu!
