Kungani Ukugeleza Kwamandla Okulwa Nokubuyela Emuva Kuhluleka: Izinkinga Ezivamile Zokuthumela Ngaphandle Kwe-Zero kanye Nezixazululo Ezisebenzayo

Isingeniso: Lapho "Ukuthunyelwa Okungaphelele" Kusebenza Ephepheni Kodwa Kuhluleka Eqinisweni

Izinhlelo eziningi ze-PV zelanga zokuhlala zihlelwe ngeakukho ukuthunyelwa ngaphandle or ukugeleza kwamandla okuphikisana nokubuyela emuvaizilungiselelo, kodwa ukufakwa kwamandla okungahlosiwe kugridi kusenzeka. Lokhu kuvame ukumangaza abafaki kanye nabanikazi bezinhlelo, ikakhulukazi lapho amapharamitha e-inverter ebonakala ehlelwe kahle.

Eqinisweni,ukugeleza kwamandla okuphikisana nokubuyela emuva akuyona isethingi eyodwa noma isici sedivayisi. Umsebenzi wezinga lesistimu oncike ekulinganisweni kokunemba, isivinini sokuphendula, ukuthembeka kokuxhumana, kanye nomklamo we-logic wokulawula. Uma noma iyiphi ingxenye yalolu chungechunge ingaphelele, ukugeleza kwamandla okubuyela emuva kusengenzeka.

Lesi sihloko siyachazakungani izinhlelo zokuthumela ngaphandle kwe-zero zingaphumeleli ekufakweni kwangempela, ikhomba izimbangela ezivame kakhulu, futhi iveza izixazululo ezisebenzayo ezisetshenziswa ezinhlelweni zesimanje ze-PV zokuhlala.

Imibuzo Evame Ukubuzwa 1: Kungani Ukugeleza Kwamandla Okubuyela Emuva Kwenzeka Ngisho Noma Kungasebenzi Ukuthunyelwa Kwe-Zero?

Enye yezinkinga ezivame kakhulu yileisivinini sokuguquguquka komthwalo.

Imithwalo yasekhaya efana nezinhlelo ze-HVAC, izifudumezi zamanzi, amashaja e-EV, kanye nezinto zasekhishini zingavula noma zivale ngemizuzwana. Uma i-inverter ithembele kuphela ekulinganisweni kwangaphakathi noma ekuthatheni isampula kancane, ingase ingaphenduli ngokushesha ngokwanele, okuvumela ukuthunyelwa kwamandla okwesikhashana.

Umkhawulo oyinhloko:

• Imisebenzi ye-inverter kuphela engeyona i-zero-export ivame ukungabi nempendulo yesikhathi sangempela evela endaweni yokuxhuma yegridi (i-PCC).

Isixazululo esiwusizo:

• Sebenzisa yangaphandle,ukulinganisa amandla egridi ngesikhathi sangempelaukuvala iluphu yokulawula.

Imibuzo Evame Ukubuzwa 2: Kungani Ngezinye izikhathi Uhlelo Lunciphisa Amandla Elanga Ngokweqile?

Ezinye izinhlelo zinciphisa ngamandla umkhiqizo we-PV ukuze zigweme ukuthumela kwamanye amazwe, okuholela ku:

• Ukuziphatha kwamandla okungazinzile

• Ukulahleka kokukhiqizwa kwelanga

• Ukusetshenziswa kabi kwamandla

Lokhu kuvame ukwenzeka lapho i-logic yokulawula ingenayo idatha yamandla eqondile futhi isebenzisa imikhawulo yokugcina ukuze "ihlale iphephile."

Imbangela:

• Impendulo yamandla ephansi noma ebambezelekile

• Imingcele eqinile esikhundleni sokulungiswa okuguquguqukayo

Indlela engcono:

• Umkhawulo wamandla ashukumisayongokusekelwe ekulinganisweni okuqhubekayo kunemingcele eqondile.

Imibuzo Evame Ukubuzwa 3: Ingabe Ukulibaziseka Kokuxhumana Kungabangela Ukwehluleka Kokulawula Okulwa Nokubuyela Emuva?

Yebo.Ukubambezeleka kanye nokungazinzi kokuxhumanangokuvamile azinakwa izimbangela zokwehluleka kokugeleza kwamandla okulwa nokuphenduka.

Uma idatha yamandla egridi ifika ohlelweni lokulawula kancane kakhulu, i-inverter isabela ezimweni eziphelelwe yisikhathi. Lokhu kungabangela ukuzulazula, impendulo ebambezelekile, noma ukuthunyelwa kwesikhashana.

Izinkinga ezivamile zifaka:

• Amanethiwekhi e-WiFi angazinzile

• Izihibe zokulawula ezincike efwini

• Izibuyekezo zedatha ezingavamile

Umkhuba onconywayo:

• Sebenzisa izindlela zokuxhumana zasendaweni noma eziseduze nesikhathi sangempela ukuze uthole impendulo enamandla noma nini lapho kungenzeka.

Imibuzo Evame Ukubuzwa 4: Ingabe Indawo Yokufakwa Kwamamitha Ithinta Ukusebenza Okungafaki Ukuthunyelwa Kwamanye Amazwe?

Impela.indawo yokufaka imitha yamandlakubalulekile.

Uma imitha ingafakwanga ku-iphuzu lokuxhumanisa okuvamile (i-PCC), kungase kulinganise ingxenye yomthwalo noma ukukhiqizwa kuphela, okuholela ezinqumweni zokulawula ezingalungile.

Amaphutha ajwayelekile:

• Imitha ifakiwe ngezansi kweminye imithwalo

• Imitha elinganisa umkhiqizo we-inverter kuphela

• Ukuqondiswa kwe-CT okungalungile

Indlela efanele:

• Faka imitha endaweni yokuxhuma yegridi lapho kungalinganiswa khona inani lokungenisa kanye nokuthumela ngaphandle.

Imibuzo Evame Ukubuzwa 5: Kungani Ukukhawulelwa Kwamandla Angaguquki Kungathembeki Emakhaya Angempela

Ukukhawulelwa kwamandla aqinile kuthatha ukuziphatha komthwalo okubikezelwayo. Eqinisweni:

• Imithwalo iyashintsha ngendlela engalindelekile

• Ukukhiqizwa kwelanga kuyashintshashintsha ngenxa yamafu

• Ukuziphatha komsebenzisi akukwazi ukulawulwa

Ngenxa yalokho, imikhawulo engaguquki ivumela ukuthunyelwa okufushane noma ikhawulele ngokweqile ukuphuma kwe-PV.

Ukulawula okuguqukayo, ngokuphambene nalokho, ilungisa amandla njalo ngokusekelwe ezimweni zesikhathi sangempela.

I-Smart Energy Meter Ibalulekile Nini Ekugelezeni Kwamandla Okulwa Nokubuyela Emuva?

Ezinhlelweni ezidingaamandla aguqukayoukulawula ukugeleza kwamandla okuphikisana nokubuyela emuva,
Impendulo yamandla egridi yesikhathi sangempela evela kumitha yamandla ehlakaniphile ibalulekile.

Imitha yamandla ehlakaniphile ivumela uhlelo ukuthi:

• Thola ukungenisa nokuthumela ngokushesha

• Bala ukuthi kudingeka ukulungiswa okungakanani

• Gcina ukugeleza kwamandla egridi kuseduze no-zero ngaphandle kokunciphisa okungadingekile

Ngaphandle kwalolu ngqimba lokulinganisa, ukulawula okulwa nokuhlehla kuncike ekulinganisweni kunezimo zangempela zegridi.

Indima ye-PC321 ekuxazululeni izinkinga zokugeleza kwamandla okulwa nokuphenduka

Ezinhlelweni ze-PV zokuhlala ezisebenzayo,Imitha yamandla ehlakaniphile ye-PC311isetshenziswa njengeireferensi yokulinganisa e-PCC.

I-PC321 inikeza:

• Ukulinganisa okunembile kwesikhathi sangempela kokungenisa nokuthumela igridi

• Imijikelezo yokuvuselela okusheshayo efanelekile kuma-loop okulawula aguqukayo

• Ukuxhumana nge-I-WiFi, i-MQTT, noma i-Zigbee

• Usekelo lwe-Izidingo zempendulo yemizuzwana engaphansi kwemibilievame ukusetshenziswa ekulawuleni i-PV yokuhlala

Ngokuletha idatha yamandla egridi ethembekile, i-PC311 ivumela ama-inverter noma izinhlelo zokuphatha amandla ukulawula ukuphuma kwe-PV ngokunembile—ukubhekana nezimbangela eziyinhloko zokuhluleka okuningi kokuthumela ngaphandle.

Okubalulekile, i-PC311 ayithathi indawo ye-logic yokulawula i-inverter. Kunalokho, i-PC311 ayithathi indawo ye-logic yokulawula i-inverter.kwenza ukulawula okuzinzile ngokunikeza idatha izinhlelo zokulawula ezithembele kuyo.

Okubalulekile: Ukugeleza Kwamandla Okulwa Nokubuyela Emuva Kuyinselele Yokuklama Uhlelo

Ukwehluleka okuningi kokugeleza kwamandla okuphikisana nokubuyela emuva akubangelwa yihadiwe enephutha. Kubangelwaukwakheka kwesistimu okungaphelele—ukungalingani kokulinganisa, ukuxhumana okulibazisekile, noma i-logic yokulawula engaguquki esetshenziswa ezindaweni eziguquguqukayo.

Ukuklama izinhlelo ezithembekile zokuthumela ngaphandle kudinga:

• Ukulinganiswa kwamandla egridi ngesikhathi sangempela

• Ukuxhumana okusheshayo nokuzinzile

• I-Log-Lock Control logic

• Ukufakwa okufanele e-PCC

Uma lezi zinto ziqondanisiwe, ukugeleza kwamandla okuphikisana nokubuyela emuva kuba yinto ebikezelwayo, ezinzile, futhi ehambisanayo.

Inothi Lokuvala Ongakukhetha

Ukuze kube nezinhlelo zelanga zasemakhaya ezisebenza ngaphansi kwemikhawulo yokuthumela kwamanye amazwe, ukuqondakungani ukukhishwa kwe-zero kwehlulekaisinyathelo sokuqala sokwakha uhlelo olusebenza ngokwethembeka ngaphansi kwezimo zangempela.
