Chifukwa Chake Kuyenda kwa Mphamvu Yotsutsana ndi Kubwerera M'mbuyo Kumalephera: Mavuto Omwe Amakhalapo Osatumiza Zinthu Kunja ndi Mayankho Othandiza

Chiyambi: Pamene "Kutumiza Zinthu Kulibe" Kugwira Ntchito Papepala Koma Sikutha Kwenikweni

Makina ambiri a PV okhala ndi mphamvu ya dzuwa amakonzedwa ndipalibe kutumiza kunja or kuyenda kwa mphamvu kosasinthamakonda, koma kulowetsa mphamvu kosayembekezereka mu gridi kumachitikabe. Izi nthawi zambiri zimadabwitsa okhazikitsa ndi eni ake a makina, makamaka pamene magawo a inverter akuwoneka kuti akonzedwa bwino.

Mu zenizeni,Kuyenda kwa mphamvu yotsutsana ndi kubwerera m'mbuyo si chinthu chimodzi kapena chipangizo chimodziNdi ntchito ya dongosolo yomwe imadalira kulondola kwa muyeso, liwiro la mayankho, kudalirika kwa kulumikizana, ndi kapangidwe ka logic yowongolera. Ngati gawo lililonse la unyolo uwu silikwanira, kuyenda kwa mphamvu yobwerera m'mbuyo kumatha kuchitikabe.

Nkhaniyi ikufotokozachifukwa chake machitidwe osatumiza kunja amalephera muzokhazikitsa zenizeni, imazindikira zomwe zimayambitsa kwambiri, ndipo imafotokoza njira zothandiza zomwe zimagwiritsidwa ntchito m'makina amakono a PV okhala.

Mafunso Ofunsidwa Kawirikawiri 1: N’chifukwa Chiyani Kuyenda kwa Mphamvu Yobwerera Kumachitika Ngakhale Kuti Zero Export Yatsegulidwa?

Chimodzi mwa nkhani zofala kwambiri ndiliwiro la kusinthasintha kwa katundu.

Katundu wapakhomo monga makina a HVAC, zotenthetsera madzi, ma charger a EV, ndi zida za kukhitchini zimatha kuyatsa kapena kuzimitsa mkati mwa masekondi. Ngati inverter imadalira kokha kuyerekezera kwamkati kapena kusanthula pang'onopang'ono, singayankhe mwachangu mokwanira, zomwe zimalola kutumiza mphamvu kwakanthawi.

Choletsa chachikulu:

• Ntchito za Inverter-only zero-export nthawi zambiri sizimalandira mayankho enieni kuchokera ku grid connection point (PCC).

Yankho lothandiza:

• Gwiritsani ntchito zakunja,muyeso wa mphamvu ya gridi nthawi yeniyenikutseka chizunguliro chowongolera.

Mafunso Ofunsidwa Kawirikawiri 2: N’chifukwa Chiyani Dongosololi Nthawi Zina Limaletsa Mphamvu ya Dzuwa Mopitirira Muyeso?

Makina ena amachepetsa kwambiri kutulutsa kwa PV kuti apewe kutumiza kunja, zomwe zimapangitsa kuti:

• Khalidwe la mphamvu losakhazikika

• Kutayika kwa kupanga kwa dzuwa

• Kugwiritsa ntchito mphamvu molakwika

Izi nthawi zambiri zimachitika pamene mfundo zowongolera zilibe deta yeniyeni ya mphamvu ndipo zimagwiritsa ntchito malire osasinthasintha kuti "zikhale zotetezeka."

Choyambitsa:

• Kuyankha kwa mphamvu yotsika kapena kuchedwa

• Mizere yosasunthika m'malo mwa kusintha kwamphamvu

Njira yabwino:

• Kuchepetsa mphamvu zamagetsikutengera muyeso wopitilira m'malo mwa malire okhazikika.

Mafunso Ofunsidwa Kawirikawiri 3: Kodi Kuchedwa kwa Kulankhulana Kungayambitse Kulephera kwa Anti-Reverse Control?

Inde.Kuchedwa ndi kusakhazikika kwa kulankhulananthawi zambiri zimanyalanyazidwa chifukwa cha kulephera kwa magetsi oletsa kubwerera m'mbuyo.

Ngati deta yamagetsi ya gridi ifika pang'onopang'ono kwambiri pamakina owongolera, inverter imachitapo kanthu pazinthu zakale. Izi zitha kubweretsa kugwedezeka, kuyankha mochedwa, kapena kutumiza kunja kwakanthawi kochepa.

Mavuto ofala ndi awa:

• Ma network a WiFi osakhazikika

• Malupu olamulira omwe amadalira mitambo

• Zosintha za data zomwe sizichitika kawirikawiri

Machitidwe olimbikitsidwa:

• Gwiritsani ntchito njira zolankhulirana zapafupi kapena nthawi yeniyeni kuti mupereke mayankho amphamvu nthawi iliyonse yomwe ingatheke.

Mafunso Ofunsidwa Kawirikawiri 4: Kodi Malo Oyikira Meter Amakhudza Kusagwira Ntchito Konse kwa Zinthu Zochokera Kunja?

Ndithudi.malo oyikapo mita yamagetsindi yofunika kwambiri.

Ngati mita siyikidwa pamfundo yolumikizirana yofanana (PCC), ingangoyesa gawo la katundu kapena kupanga, zomwe zimapangitsa kuti pakhale zisankho zolakwika zowongolera.

Zolakwika wamba:

• Mita yoyikidwa pansi pa katundu wina

• Choyezera mita chokhacho chotulutsa inverter

• Kulunjika kolakwika kwa CT

Njira yolondola:

• Ikani mita pamalo olumikizira gridi pomwe mutha kuyeza kuchuluka kwa zinthu zomwe zimalowa ndi zomwe zimatumizidwa kunja.

Mafunso Ofunsidwa Kawirikawiri 5: Chifukwa Chake Kuletsa Mphamvu Yosasunthika N'kosadalirika M'nyumba Zenizeni

Kuchepetsa mphamvu yosasunthika kumatanthauza kuti katundu amayendetsedwa bwino. Zoona zake n'zakuti:

• Katundu amasintha mosayembekezereka

• Kupanga kwa dzuwa kumasintha chifukwa cha mitambo

• Khalidwe la ogwiritsa ntchito silingathe kulamulidwa

Zotsatira zake, malire osasinthasintha amalola kutumiza kwa kanthawi kochepa kapena kuletsa kwambiri kutulutsa kwa PV.

Kulamulira kwamphamvuMosiyana ndi zimenezi, imasintha mphamvu nthawi zonse kutengera momwe zinthu zilili panthawi yeniyeni.

Kodi mita yamagetsi yanzeru ndi yofunikira liti pakuyenda kwamagetsi kotsutsana ndi kusinthasintha?

Mu machitidwe omwe amafunikiramphamvukuwongolera kayendedwe ka mphamvu kotsutsana ndi kubwerera m'mbuyo,
Kuyankha kwa mphamvu ya gridi yeniyeni kuchokera ku mita yamagetsi yanzeru ndikofunikira.

Chida choyezera mphamvu chanzeru chimalola dongosololi kuti:

• Dziwani kulowetsa ndi kutumiza nthawi yomweyo

• Kuwerengera kuchuluka kwa kusintha komwe kumafunika

• Sungani kuyenda kwa magetsi pa gridi pafupifupi zero popanda kuchepetsa kosafunikira

Popanda gawo loyezera ili, kulamulira kotsutsana ndi kubwerera m'mbuyo kumadalira kuyerekezera osati momwe zinthu zilili pa gridi yeniyeni.

Udindo wa PC321 pakuthetsa mavuto okhudzana ndi kayendedwe ka mphamvu yotsutsana ndi kubwerera m'mbuyo

Mu makina ogwiritsira ntchito ma PV okhala m'nyumba,Mita yamagetsi yanzeru ya PC311imagwiritsidwa ntchito ngatiumboni woyezera ku PCC.

PC321 imapereka:

• Muyeso wolondola wa kutumiza ndi kutumiza gridi nthawi yeniyeni

• Kusintha mwachangu koyenera ma dynamic control loops

• Kulankhulana kudzera paWiFi, MQTT, kapena Zigbee

• Thandizo laZofunikira pakuyankha kwa masekondi awiriamagwiritsidwa ntchito kwambiri poyang'anira ma PV m'nyumba

Popereka deta yodalirika yamagetsi a gridi, PC311 imalola ma inverter kapena makina oyang'anira mphamvu kuti azilamulira kutulutsa kwa PV molondola—kuthana ndi zomwe zimayambitsa kulephera kwakukulu kwa kutumiza kunja.

Chofunika kwambiri n'chakuti, PC311 siilowa m'malo mwa inverter control logic. M'malo mwake, imalowa m'malo mwa inverter control logic.zimathandiza kulamulira kokhazikika popereka deta yomwe machitidwe owongolera amadalira.

Mfundo Yofunika Kuiganizira: Kuyenda kwa Mphamvu Yotsutsana ndi Kubwerera M'mbuyo Ndi Vuto Lopanga Kapangidwe ka Dongosolo

Kulephera kwa magetsi ambiri oletsa kubwerera m'mbuyo sikumachitika chifukwa cha hardware yolakwika.kapangidwe ka dongosolo kosakwanira—kusowa kwa muyeso, kuchedwa kwa kulankhulana, kapena njira yowongolera yosasinthasintha yogwiritsidwa ntchito ku malo osinthasintha.

Kupanga njira zodalirika zosatumizira kunja kumafuna:

• Muyeso wa mphamvu ya gridi yeniyeni

• Kulankhulana mwachangu komanso kokhazikika

• Ndondomeko yolamulira yotsekedwa

• Kukhazikitsa koyenera ku PCC

Zinthu izi zikagwirizana, kuyenda kwa mphamvu yotsutsana ndi kubwerera m'mbuyo kumakhala kodziwikiratu, kokhazikika, komanso kogwirizana.

Chidziwitso Chotseka Chosankha

Kumvetsetsa makina a dzuwa okhala m'nyumba omwe amagwira ntchito motsatira malamulo oletsa kutumiza kunjachifukwa chake palibe kutumiza kunja komwe kwalepherandi sitepe yoyamba yopangira dongosolo lomwe limagwira ntchito modalirika pansi pa mikhalidwe yeniyeni.
