Isingeniso: Kungani Ukugeleza Kwamandla Okubuyela Emuva Kube Yinkinga Yangempela
Njengoba izinhlelo ze-PV zelanga zasemakhaya ziya ngokuya zivamile, abanikazi bezindlu abaningi bacabanga ukuthi ukuthumela ugesi owengeziwe emuva kugridi kuyamukeleka ngaso sonke isikhathi. Eqinisweni,ukugeleza kwamandla okuphambene—lapho ugesi ugeleza usuka ohlelweni lwelanga lwendlu ubuyela kugridi yomphakathi—sekuyindaba ekhulayo ngezinsizakusebenza emhlabeni jikelele.
Ezindaweni eziningi, ikakhulukazi lapho amanethiwekhi okusabalalisa ama-voltage aphansi ayengaklanyelwanga ekuqaleni ukugeleza kwamandla okuqondiswa kwezinhlangothi ezimbili, ukufakwa kwegridi okungalawulwa kungabangela ukungazinzi kwe-voltage, ukungasebenzi kahle kokuvikela, kanye nezingozi zokuphepha. Ngenxa yalokho, izinsiza zilethaizidingo zokugeleza kwamandla okungekho mpahla noma eziphikisana nokubuya emuvaukufakwa kwe-PV yezindlu kanye neyebhizinisi elincane.
Lokhu kuholele abanikazi bezindlu, abafaki bezindlu, kanye nabaklami bezinhlelo ukuthi babuze umbuzo obalulekile:
Ukugeleza kwamandla okuhoxiswa emuva kungatholakala kanjani ngokunembile futhi kulawulwe ngesikhathi sangempela ngaphandle kokudela ukuzisebenzisa kwelanga?
Kuyini Ukugeleza Kwamandla Okubuyela Emuva Kuhlelo Lwe-PV Lokuhlala?
Ukugeleza kwamandla abuyela emuva kwenzeka lapho ukukhiqizwa kwamandla elanga okusheshayo kudlula ukusetshenziswa kwekhaya lendawo, okubangela ukuthi ugesi owengeziwe ugeleze ubuyele emuva kugridi yokusetshenziswa.
Izimo ezijwayelekile zifaka:
-
Iziqongo zelanga zasemini ezinomthwalo ophansi wasekhaya
-
Izindlu zihlonyiswe ngama-PV arrays amakhulu kakhulu
-
Izinhlelo ezingenawo ukugcinwa kwamandla noma ukulawulwa kokuthumela kwamanye amazwe
Ngokombono wegridi, lokhu kugeleza kwezinhlangothi ezimbili kungaphazamisa ukulawulwa kwamandla kagesi kanye nokulayisha kwe-transformer. Ngokombono womnikazi wendlu, ukugeleza kwamandla okubuyela emuva kungaholela ku:
-
Izinkinga zokuthobela imithetho yegridi
-
Ukuvalwa kwe-inverter okuphoqelelwe
-
Ukuvunyelwa kwesistimu okuncishisiwe noma izinhlawulo ezimakethe ezilawulwayo
Kungani Izinsiza Zidinga Ukulawulwa Kokugeleza Kwamandla Okulwa Nokubuyela Emuva
Izinsiza ziphoqelela izinqubomgomo zokugeleza kwamandla okulwa nokubuyela emuva ngezizathu eziningana zobuchwepheshe:
-
Ukulawulwa kwe-voltage: Ukukhiqizwa ngokweqile kungacindezela i-grid voltage ngale kwemingcele ephephile.
-
Ukuhlanganiswa kokuvikelwa: Amadivayisi okuvikela akudala athatha ukugeleza okuqondile.
-
Ukuzinza kwenethiwekhi: Ukungena okuphezulu kwe-PV engalawulwa kungaphazamisa ukuzinza kwama-feeder ane-voltage ephansi.
Ngenxa yalokho, opharetha abaningi begridi manje badinga izinhlelo ze-PV zokuhlala ukuze zisebenze ngaphansi kwalokhu:
-
Imodi yokuthumela ngaphandle kwe-Zero
-
Umkhawulo wamandla ashukumisayo
-
Imikhawulo yokuthumela ngaphandle enemibandela
Zonke lezi zindlela zincike esicini esisodwa esibalulekile:ukulinganisa okunembile, kwesikhathi sangempela kokugeleza kwamandla endaweni yokuxhuma igridi.
Indlela Ukugeleza Kwamandla Okubuyela Emuva Okutholakala Ngayo Emsebenzini
Ukugeleza kwamandla abuyela emuva akunqunywa ngaphakathi kwe-inverter kuphela. Kunalokho, kumele kulinganisweendaweni lapho isakhiwo sixhuma khona negridi.
Lokhu kuvame ukufezwa ngokufaka i-imitha yamandla ehlakaniphile esekelwe ku-clampentanjeni kagesi eyinhloko engenayo. Imitha iqapha njalo:
-
Isiqondiso samandla asebenzayo (ukungenisa vs ukuthumela ngaphandle)
-
Izinguquko zomthwalo ezisheshayo
-
Ukusebenzisana kwegridi ye-net
Uma kutholakala ukuthunyelwa kwamanye amazwe, imitha ithumela impendulo yesikhathi sangempela kumlawuli wokuphatha amandla noma we-inverter, okuvumela isinyathelo sokulungisa ngokushesha.
Indima Yemitha Yamandla Ehlakaniphile Ekulawuleni Ukugeleza Kwamandla Okulwa Nokubuyela Emuva
Kuhlelo lokugeleza kukagesi oluphikisana nokujika emuva oluhlala ekhaya, imitha yamandla isebenza njengeireferensi yesinqumokunokuba kube yidivayisi yokulawula uqobo.
Isibonelo esimele yilesiOkwa-OWONImitha yamandla ehlakaniphile ye-PC321 WiFi, eyenzelwe ukulinganisa okusekelwe ku-clamp endaweni yokuxhuma igridi. Ngokuqapha ubukhulu kanye nesiqondiso sokugeleza kwamandla, imitha inikeza idatha ebalulekile edingekayo ku-logic yokulawula ukuthumela kwamanye amazwe.
Izici ezibalulekile ezidingekayo kule ndima zifaka:
-
Ukusampula okusheshayo nokubika
-
Ukutholwa kwesiqondiso okuthembekile
-
Ukuxhumana okuguquguqukayo kokuhlanganiswa kwe-inverter
-
Ukusekelwa kwezinhlelo zokuhlala zesigaba esisodwa kanye nesigaba esihlukanisiwe
Esikhundleni sokunciphisa ukukhiqizwa kwelanga ngokungazi, le ndlela ivumelaukulungiswa okuguquguqukayongokusekelwe ekufunweni kwangempela kwasekhaya.
Amasu Okulawula Ukugeleza Kwamandla Okulwa Nokubuyela Emuva
Ukulawulwa Okungekho Kokuthumela Ngaphandle
Umphumela we-inverter uyalungiswa ukuze ukuthunyelwa kwegridi kuhlale ku-zero noma kuseduze no-zero. Le ndlela isetshenziswa kabanzi ezifundeni ezinezinqubomgomo zegridi eziqinile.
Ukukhawulelwa Kwamandla Ashukumisayo
Esikhundleni somkhawulo ohleliwe, umkhiqizo we-inverter ulungiswa njalo ngokusekelwe ekulinganisweni kwegridi ngesikhathi sangempela, okuthuthukisa ukusebenza kahle kokusebenzisa wena.
Ukuhlanganiswa kwe-Hybrid PV + Isitoreji
Ezinhlelweni ezinamabhethri, amandla asele angaqondiswa endaweni yokugcina ngaphambi kokuba kuthunyelwe kwamanye amazwe, kanti imitha yamandla isebenza njengendawo yokuqalisa.
Kuzo zonke izimo,impendulo yesikhathi sangempela evela endaweni yokuxhuma yegridikubalulekile ekusebenzeni okuzinzile nokuhambisana nemithetho.
Izinto Okufanele Uzicabangele Zokufaka: Lapho Imitha Kufanele Ibekwe Khona
Ukuze uthole ukulawula okunembile kokugeleza kwamandla okulwa nokuhlehla:
-
Imitha yamandla kumele ifakwephezulu kwayo yonke imithwalo yasekhaya
-
Ukulinganisa kumele kwenzeke ku-Uhlangothi lwe-ACesibonakalayo segridi
-
Ama-CT clamp kumele avale ngokuphelele umqhubi oyinhloko
Ukubekwa okungalungile—njengokulinganisa kuphela umkhiqizo we-inverter noma imithwalo ngayinye—kuzoholela ekutholakaleni kokuthunyelwa ngaphandle okungathembekile kanye nokuziphatha kokulawula okungazinzile.
Izinto Okucatshangelwayo Ngokusetshenziswa Kwabahlanganisi Namaphrojekthi Amandla
Ezindaweni zokuhlala ezinkulu noma ezifakwe ngokusekelwe kumaphrojekthi, ukulawulwa kokugeleza kwamandla okuphikisana nokubuyela emuva kuba yingxenye yomklamo wesistimu ebanzi.
Izinto ezibalulekile okufanele uzicabangele zifaka:
-
Ukuzinza kokuxhumana phakathi kwemitha kanye ne-inverter
-
Amandla okulawula endawo ngaphandle kokuxhumeka kwefu
-
Ukwanda kokufakwa okuningi
-
Ukuhambisana nemikhiqizo ehlukene ye-inverter
Abakhiqizi bathandaI-OWON, ngemikhiqizo yokulinganisa amandla ahlakaniphile ezinikele njenge-PC321, inikeza ihadiwe yokulinganisa engalungiselelwa izinhlelo zamandla zokuhlala, ezentengiselwano, kanye nezinhlelo zamandla ezisekelwe kumaphrojekthi ezidinga ukulawulwa okuthembekile kokuthunyelwa kwamanye amazwe.
Isiphetho: Ukulinganisa Okunembile Kuyisisekelo Sokugeleza Kwamandla Okulwa Nokubuyela Emuva
Ukulawula ukugeleza kwamandla okuphikisana nokubuyela emuva akusakhethwa ezimakethe eziningi zelanga zokuhlala. Ngenkathi ama-inverter enza izenzo zokulawula,amamitha kagesi ahlakaniphile ahlinzeka ngesisekelo sokulinganisa okubucayiokuvumela ukusebenza okuphephile, okuhambisanayo, futhi okuphumelelayo.
Ngokuqonda ukuthi ukugeleza kwamandla okuphambene kutholakala kuphi futhi kanjani—nangokukhetha amadivayisi okulinganisa afanele—abanikazi bezindlu nabaklami bezinhlelo bangagcina ukuhambisana kwegridi ngaphandle kokubeka engcupheni ukusetshenziswa kwamandla elanga.
Ukubizelwa Esenzweni
Uma uklama noma usebenzisa izinhlelo zelanga zokuhlala ezidinga ukulawulwa kokugeleza kwamandla okulwa nokujika emuva, ukuqonda ungqimba lokulinganisa kubalulekile.
Hlola ukuthi amamitha wamandla ahlakaniphile asekelwe ku-clamp afana ne-PC321 ye-OWON angasekela kanjani ukuqapha okunembile ohlangothini lwegridi kanye nokulawula kwesikhathi sangempela ekufakweni kwe-PV yesimanje.
