Momwe Mphamvu Yotsutsana ndi Kubwerera M'mbuyo Imagwirira Ntchito mu Ma Solar Systems Okhalamo: Phunziro la Kapangidwe ka Dongosolo

Chiyambi: Kuchokera ku Chiphunzitso mpaka ku Kulamulira Mphamvu Yotsutsana ndi Kubwerera M'mbuyo Padziko Lonse

Pambuyo pomvetsetsa mfundo zomwe zili kumbuyopalibe kutumiza kunjandikuchepetsa mphamvu zamagetsi, opanga makina ambiri akukumanabe ndi funso lothandiza:

Kodi makina oyendetsera magetsi otsutsana ndi kutembenuka amagwira ntchito bwanji mu malo enieni okhala ndi mphamvu ya dzuwa?

Mwachidule, mphamvu yotsutsana ndi kubwerera m'mbuyo siipezeka ndi chipangizo chimodzi.kapangidwe ka dongosolo kogwirizanazomwe zimaphatikizapo kuyeza, kulankhulana, ndi kuwongolera. Popanda kapangidwe ka makina omveka bwino, ngakhale ma inverter okonzedwa bwino angalepheretse kutumiza gridi yosayembekezereka pansi pa mikhalidwe yosinthika ya katundu.

Nkhaniyi ikuperekakafukufuku wamba wa nyumba zokhala ndi dzuwa, kufotokoza momwe mphamvu yoyendetsera magetsi yotsutsana ndi kubwerera m'mbuyo imagwirira ntchito pamlingo wa dongosolo komanso chifukwa chakeKuyeza mphamvu yeniyeni pamalo olumikizira gridi ndikofunikira kwambiri.

Zochitika Zachizolowezi za PV Zokhalamo Zofuna Kuwongolera Zotsutsana ndi Kubwerera M'mbuyo

Taganizirani nyumba ya banja limodzi yokhala ndi:

• Dongosolo la PV la dzuwa la padenga

• Chosinthira cholumikizidwa ndi gridi

• Zinthu zapakhomo zomwe zimasinthasintha pafupipafupi

• Malamulo amagetsi omwe amaletsa kutumiza magetsi kunja

Muzochitika zotere, kugwiritsa ntchito magetsi m'nyumba kungachepe mwadzidzidzi—monga zipangizo zikamazima—pamene kupanga magetsi a PV kumakhalabe kwakukulu. Popanda mphamvu yolamulira, mphamvu yochulukirapo idzabwerera mu gridi mkati mwa masekondi.

Kupewa izi kumafunamayankho opitilira komanso yankho lachangu, osati kasinthidwe kosasunthika.

Chidule cha Kapangidwe ka Dongosolo: Zigawo Zofunika

Dongosolo lamphamvu loletsa kusinthasintha kwa mphamvu nthawi zambiri limakhala ndi zigawo zinayi zogwira ntchito:

1. Gawo Loyezera Gridi

2. Gawo Lolumikizirana

3. Gawo Lowongolera Loyenera

4. Gawo Losintha Mphamvu

Gawo lililonse limagwira ntchito inayake pakusunga kutsata malamulo ndi kukhazikika kwa dongosolo.

Gawo 1: Kuyeza Mphamvu ya Gridi Pa Nthawi Yeniyeni

Pa maziko a dongosololi palimuyeso wa nthawi yeniyeni pamalo olumikizirana wamba (PCC).

Chida choyezera mphamvu chanzeru chomwe chimayikidwa pa gridi yolumikizira chimayesa nthawi zonse:

• Mphamvu yotumizidwa kunja

• Mphamvu yotumizidwa kunja

• Kuyenda kwa mphamvu ya intaneti

Muyeso uwu uyenera kukhala:

• Zolondola

• Mosalekeza

• Mofulumira mokwanira kuti ziwonetse kusintha kwa katundu

Popanda deta iyi, dongosololi silingathe kudziwa ngati mphamvu yobwerera m'mbuyo ikuchitika.

Gawo 2: Kulumikizana Pakati pa Meter ndi Control System

Deta yoyezera iyenera kutumizidwa ku dongosolo lowongolera popanda kuchedwa kwambiri.

Njira zolankhulirana zodziwika bwino ndi izi:

• Wifiza maukonde okhala

• MQTTkuti igwirizane ndi machitidwe oyang'anira mphamvu

• Zigbeeza zomangamanga zochokera pachipata chapafupi

Kulankhulana kokhazikika kumatsimikizira kuti mphamvu yobwezera ifika pa mfundo zowongolera nthawi yomweyo.

Gawo 3: Kulamulira Maganizo ndi Kupanga Zisankho

Dongosolo lowongolera—lomwe limagwiritsidwa ntchito mu inverter controller kapena dongosolo loyang'anira mphamvu—limapitiliza kuwunika momwe mphamvu ya gridi imagwirira ntchito.

Malingaliro wamba amaphatikizapo:

• Ngati kutumiza kunja > 0 W → kuchepetsa kutulutsa kwa PV

• Ngati kulowetsa > malire → lolani PV ikwere

• Pakani kusalala kuti musagwedezeke

Malingaliro amenewa amayenda mosalekeza, kupangadongosolo lolamulira lotsekedwa.

Gawo 4: Kusintha kwa PV Output

Kutengera ndi zisankho zowongolera, inverter imasintha mphamvu ya PV modabwitsa:

• Kuchepetsa kupanga zinthu panthawi yolemera pang'ono

• Kuchuluka kwa zokolola pamene kufunikira kwa mabanja kukukwera

• Kusunga kayendedwe ka mphamvu ya gridi pa kapena pafupi ndi zero

Mosiyana ndi makonda osatumiza zinthu kunja, njira iyi imalola makinawo kuyankha pazochitika zenizeni.

Kumene Chiyeso cha Mphamvu Yanzeru Chikugwirizana: Udindo wa PC321

Mu kapangidwe kameneka,PC321mita yamagetsi yanzeruamagwira ntchito ngatinangula woyezera wa dongosolo lonse.

PC321 imapereka:

• Muyeso weniweni wa kutumiza ndi kutumiza kunja kwa gridi

• Zosintha za data mwachangu zoyenera ma dynamic control loops

• Kulankhulana kudzera paWiFi, MQTT, kapena Zigbee

• Nthawi yoyankhira yomwe ingathandizekusintha kwa mphamvu ya masekondi awiri

Mwa kupereka mayankho olondola a mphamvu ya gridi, PC321 imalola makina owongolera kuti azilamulira bwino kutulutsa kwa PV—kuletsa kuyenda kwa mphamvu kumbuyo popanda kuchepetsa kupanga kwa dzuwa mosafunikira.

Chofunika kwambiri, PC321 siichita zinthu zowongolera inverter yokha. M'malo mwake, imachita izi.zimathandiza kulamulira kodalirika popereka deta yoyezera yomwe zisankho zonse zapamwamba zimadalira.

Chifukwa Chake Kutumiza Zinthu Zosasintha Nthawi Zambiri Kumalephera M'nyumba Zenizeni

M'nyumba zenizeni, kusintha kwa katundu sikungatheke kudziwika:

• Zipangizo zimayatsa ndi kuzimitsa

• Ma charger a EV amayamba mwadzidzidzi

• Mapampu otenthetsera ndi machitidwe a HVAC

Zokonzera zosagwiritsa ntchito inverter zomwe sizikutumiza kunja sizingayankhe mwachangu mokwanira ku zochitika izi. Zotsatira zake ndi izi:

• Kutumiza kwa gridi kwakanthawi

• Kuchepetsa kwambiri PV

Kuwongolera kogwiritsa ntchito mita kumapereka yankho lokhazikika komanso lothandiza kwambiri.

Zoganizira Zokhudza Kutumizidwa kwa Ma Residential Anti-Reverse Systems

Popanga njira yoyendetsera magetsi yotsutsana ndi kubwereranso, ganizirani izi:

• Malo oyika mita ku PCC

• Kudalirika kwa kulumikizana pakati pa zipangizo

• Nthawi yoyankhira kuzungulira koyenera

• Kugwirizana ndi nsanja za inverter kapena EMS

Kapangidwe kokonzedwa bwino kamatsimikizira kutsatira malamulo popanda kuwononga kugwiritsa ntchito mphamvu.

Mapeto: Kapangidwe ka Nyumba N'kofunika Kwambiri Kuposa Zipangizo Zapadera

Kulamulira kayendedwe ka mphamvu kotsutsana ndi kubwerera m'mbuyosizimatheka poletsa kupanga kwa dzuwa. Ndi zotsatira zakapangidwe ka dongosolo kogwirizana bwinokumene kuyeza, kulankhulana, ndi kulamulira zimagwirira ntchito limodzi nthawi yeniyeni.

Pamene makina a PV okhala m'nyumba akuyamba kusinthasintha,Mamita anzeru amagetsi pa gridi yolumikizira akhala gawo loyambiranjira zothandiza zotsutsana ndi kusintha kwa magetsi.

Pa mapulojekiti okhala ndi mphamvu ya dzuwa omwe amafunikira kuwongolera bwino kutumiza kunja, kumvetsetsa kapangidwe ka makina ndi gawo loyamba lopita ku kukhazikitsidwa kokhazikika komanso kotsatira malamulo.
