MPPT vs. PWM: Ndi chowongolera chiti chomwe chili chabwino kwambiri pa kuwala kwachikasu kowala ndi dzuwa?

Mu gawo la mayankho a dzuwa,magetsi achikasu owunikira dzuwaakhala gawo lofunika kwambiri pa ntchito zosiyanasiyana kuphatikizapo kuyang'anira magalimoto, malo omanga, ndi zizindikiro zadzidzidzi. Monga wogulitsa wodziwa bwino ntchito za magetsi achikasu owunikira dzuwa, Qixiang akumvetsa kufunika kosankha chowongolera choyenera kuti chigwire bwino ntchito magetsi awa. Pali mitundu iwiri ikuluikulu ya zowongolera mphamvu ya dzuwa zomwe zimagwiritsidwa ntchito kwambiri pamagetsi a dzuwa: Maximum Power Point Tracking (MPPT) ndi Pulse Width Modulation (PWM). Nkhaniyi ifotokoza kusiyana pakati pa zowongolera za MPPT ndi PWM ndikuthandizani kusankha chowongolera chomwe chili choyenera zosowa zanu za kuwala kwachikasu kowunikira dzuwa.

Dziwani zambiri za zowongolera mphamvu ya dzuwa

Musanaganize mozama za kufananiza kumeneku, ndikofunikira kumvetsetsa zomwe chowongolera mphamvu ya dzuwa chimachita. Zipangizozi zimawongolera mphamvu yamagetsi ndi mphamvu yamagetsi kuchokera ku ma solar panels kupita ku batri, kuonetsetsa kuti batriyo yachajidwa bwino komanso mosamala. Kusankha chowongolera kumatha kukhudza kwambiri magwiridwe antchito ndi moyo wautali wa makina anu amagetsi achikasu owunikira dzuwa.

Olamulira a PWM

Olamulira a Pulse width modulation (PWM) ndi mtundu wachikhalidwe wa solar charge controller. Amagwira ntchito polumikiza solar panel mwachindunji ku batri ndikugwiritsa ntchito zizindikiro zingapo zosinthira kuti azilamulira njira yolipirira. M'lifupi mwa chizindikiro cha "pa" chimasintha kutengera momwe batri ilili, zomwe zimapangitsa kuti njira yolipirira ikhale yokhazikika komanso yowongoka.

Ubwino wa Olamulira a PWM:

1. Yosavuta komanso yotsika mtengo:

Ma controller a PWM nthawi zambiri amakhala otsika mtengo komanso osavuta kuyika kuposa ma controller a MPPT. Izi zimapangitsa kuti akhale chisankho chokopa mapulojekiti omwe amaganizira bajeti.

2. Kudalirika:

Chifukwa cha zigawo zochepa komanso mapangidwe osavuta, owongolera a PWM nthawi zambiri amakhala odalirika kwambiri ndipo safuna kukonza kwambiri.

3. Kuchita Bwino M'machitidwe Ang'onoang'ono:

Pa makina ang'onoang'ono a dzuwa omwe magetsi a solar panel amagwirizana kwambiri ndi magetsi a batri, mphamvu ya chowongolera cha PWM imakhala yokwera kwambiri.

Olamulira a MPPT

Ma controller a Maximum Power Point Tracking (MPPT) ndi ukadaulo wapamwamba kwambiri womwe umawongolera mphamvu zomwe zimatengedwa kuchokera ku ma solar panels. Amayang'anira nthawi zonse kutulutsa kwa ma solar panels ndikusintha malo ogwirira ntchito amagetsi kuti atsimikizire kuti mphamvu zambiri zatulutsidwa.

Ubwino wa MPPT Controller:

1. Kuchita Bwino Kwambiri:

Poyerekeza ndi olamulira a PWM, olamulira a MPPT amatha kuwonjezera mphamvu ya machitidwe a dzuwa ndi 30%, makamaka pamene magetsi a solar panel ali apamwamba kuposa magetsi a batri.

2. Kugwira ntchito bwino mumdima wochepa:

Chowongolera cha MPPT chimagwira ntchito bwino mumdima wochepa, zomwe zimapangitsa kuti chikhale choyenera kuwunikira kwachikasu cha dzuwa komwe kumafunika kugwira ntchito bwino ngakhale masiku a mitambo kapena madzulo.

3. Kusinthasintha kwa kapangidwe ka dongosolo:

Olamulira a MPPT amalola kusinthasintha kwakukulu pakupanga makina kuti agwiritse ntchito ma solar panels amphamvu kwambiri, zomwe zingachepetse ndalama zolumikizira mawaya ndi kutayika.

Ndi chowongolera chiti chomwe chili chabwino kwambiri pa kuwala kwachikasu kwa dzuwa?

Posankha ma MPPT ndi ma PWM controller a kuwala kwachikasu kwa dzuwa, chisankhocho chimadalira kwambiri zofunikira za pulogalamu yanu.

- Pa Mapulojekiti Ang'onoang'ono, Okhala ndi Ndalama Zochepa: Ngati mukugwira ntchito pa projekiti yaying'ono yokhala ndi bajeti yochepa, chowongolera cha PWM chingakhale chokwanira. Ndi chodalirika, chotsika mtengo, ndipo chingapereke mphamvu zokwanira zowunikira magetsi achikasu a dzuwa pansi pa mikhalidwe yabwino.

- Pa ntchito zazikulu kapena zovuta kwambiri: Ngati pulojekiti yanu ikufuna kugwira ntchito bwino, makamaka pamene kuwala kukusintha, chowongolera cha MPPT ndiye chisankho chabwino. Kugwira ntchito bwino komanso kugwira ntchito bwino pamene kuwala kutsika kumapangitsa kuti zowongolera za MPPT zikhale zabwino kwambiri poonetsetsa kuti magetsi anu achikasu owunikira a dzuwa akugwira ntchito moyenera nthawi zonse.

Pomaliza

Monga kampani yodalirika yopereka magetsi achikasu owunikira dzuwa, Qixiang yadzipereka kupereka zinthu zapamwamba komanso malangizo a akatswiri kuti akuthandizeni kusankha bwino kwambiri magetsi a dzuwa. Kaya mwasankha chowongolera cha PWM kapena MPPT, kumvetsetsa kusiyana ndi ubwino wa chilichonse kungakuthandizeni kusankha njira yoyenera ya makina anu achikasu owunikira dzuwa.

Kuti mupeze mtengo woperekedwa ndi munthu kapena thandizo lina posankha yoyenerakuwala kwa dzuwa kwachikasu kowala ndi chowongoleraPa ntchito yanu, chonde musazengereze kulankhulana ndi Qixiang. Tili pano kuti tikupatseni njira zodalirika zowunikira njira yanu yogwiritsira ntchito mphamvu ya dzuwa!
