Ukuhamba kwamandla okuchasene nokubuyela umva kwiinkqubo zelanga zokuhlala: Kutheni kubalulekile kwaye ungayilawula njani

Intshayelelo: Kutheni Ukuhamba Kombane Okubuyela Umva Kube Yingxaki Yokwenene

Njengoko iinkqubo ze-PV zelanga ezihlala abantu ziya zisanda, abanini bezindlu abaninzi bacinga ukuba ukuthumela umbane ogqithisileyo kwigridi kusoloko kwamkelekile. Enyanisweni,ukuhamba kwamandla ngasemva—xa umbane uphuma kwinkqubo yelanga yekhaya ubuyela kwigridi kawonke-wonke—uye waba yinkxalabo ekhulayo kwiinkonzo zikawonke-wonke.

Kwimimandla emininzi, ingakumbi apho iinethiwekhi zokusasazwa kwe-voltage ephantsi zazingenzelwanga ukuhamba kombane okuya kwicala elinye, ukufakwa kwegridi engalawulwayo kunokubangela ukungazinzi kwe-voltage, ukungasebenzi kakuhle kokhuseleko, kunye neengozi zokhuseleko. Ngenxa yoko, iinkonzo zingenisaiimfuno zokuhamba kwamandla ngaphandle okanye ezichasene nokubuyela umvaukufakelwa kwe-PV kwiindawo zokuhlala nakwiindawo zorhwebo ezincinci.

Oku kukhokelele abanini bezindlu, abafaki bezindlu, kunye nabayili beenkqubo ukuba babuze umbuzo obalulekileyo:
Ukuhamba kwamandla okujika umva kungafunyanwa njani ngokuchanekileyo kwaye kulawulwe ngexesha langempela ngaphandle kokulahla ukuzisebenzisa ngokwakho kwelanga?

Yintoni iReverse Power Flow kwiResidential PV System?

Ukuhamba kombane okubuyela umva kwenzeka xa ukuveliswa kwamandla elanga ngoko nangoko kudlula ukusetyenziswa kwekhaya, nto leyo ebangela ukuba umbane ongaphezulu ubuyele kwigridi yombane.

Iimeko eziqhelekileyo ziquka:

• Iincopho zelanga zasemini ezinomthwalo omncinci wasekhaya

• Izindlu zixhotyiswe ngee-PV arrays ezinkulu kakhulu

• Iinkqubo ezingenawo ugcino lwamandla okanye ulawulo lokuthumela ngaphandle

Ngokwembono yegridi, olu hambo luhamba ngamacandelo amabini lunokuphazamisa ukulawulwa kwevolthi kunye nomthwalo wetransformer. Ngokwembono yomninimzi, ukuhamba kombane okubuyela umva kunokukhokelela koku:

• Iingxaki zokuthobela igridi

• Ukuvalwa kwe-inverter okunyanzelekileyo

• Ukuncitshiswa kwemvume yenkqubo okanye izohlwayo kwiimarike ezilawulwayo

Kutheni Izixhobo Zifuna Ulawulo Lokuhamba Kombane Oluchasene Nokubuyela Umva

Izixhobo zinyanzelisa imigaqo-nkqubo yokuchasana nokuhamba kwamandla okujika emva ngenxa yezizathu ezahlukeneyo zobugcisa:

• Ulawulo lweVolthi: Ukuveliswa okugqithisileyo kunokutyhala i-voltage yegridi ngaphaya kwemida ekhuselekileyo.

• Ulungelelwaniso lokhuselekoIzixhobo zokukhusela zakudala zithatha ukuhamba kwecala elinye.

• Uzinzo lwenethiwekhi: Ukungena okuphezulu kwe-PV engalawulwayo kunokuphazamisa ukuzinza kwezixhobo zokondla ezine-voltage ephantsi.

Ngenxa yeso sizathu, uninzi lwabaqhubi begridi ngoku bafuna iinkqubo ze-PV zokuhlala ukuze zisebenze phantsi kwezi zilandelayo:

• Imo yokuthumela ngaphandle kwe-Zero

• Ukunciphisa amandla ashukumisayo

• Imida yokuthumela ngaphandle enemiqathango

Zonke ezi ndlela zixhomekeke kwinto enye ebalulekileyo:umlinganiselo ochanekileyo, wexesha langempela wokuhamba kwamandla kwindawo yoqhagamshelo lwegridi.

Indlela iReverse Power Flow efunyanwa ngayo xa kusenziwa

Ukuhamba kwamandla abuyela umva akumiselwanga ngaphakathi kwi-inverter yodwa. Endaweni yoko, kufuneka kulinganiswekwindawo apho isakhiwo siqhagamshela khona kwigridi.

Oku kudla ngokufezekiswa ngokufaka iimitha yamandla ekrelekrele esekelwe kwi-clampkwintambo yombane eyintloko engenayo. Imitha isoloko ijonga:

• Isikhokelo samandla asebenzayo (ukungenisa kunye nokuthumela ngaphandle)

• Utshintsho lomthwalo olukhawulezileyo

• Ukusebenzisana kwegridi ye-intanethi

Xa kufunyenwe ukuthunyelwa kwamanye amazwe, imitha ithumela impendulo ngexesha langempela kwi-inverter okanye kumlawuli wolawulo lwamandla, nto leyo evumela ukuba kuthathwe amanyathelo okulungisa ngokukhawuleza.

Indima yeMitha yamandla ekrelekrele kuLawulo lokuHamba koMbane oluchasene nokuBuya kweNdlela

Kwinkqubo yokuhamba kombane echasene nokubuyela umva kwendlu, imitha yamandla isebenza njengeisalathiso sesigqiboendaweni yesixhobo sokulawula ngokwaso.

Umzekelo omeleyo nguloIi-OWON'sImitha yamandla ehlakaniphile ye-PC321 WiFi, eyenzelwe ukulinganisa okusekwe kwi-clamp kwindawo yoqhagamshelo lwegridi. Ngokujonga ubukhulu kunye necala lokuhamba kwamandla, imitha ibonelela ngedatha ebalulekileyo efunekayo kwi-logic yolawulo lokuthumela ngaphandle.

Iimpawu eziphambili ezifunekayo kule ndima ziquka:

• Isampuli ekhawulezayo kunye nengxelo

• Ukufunyanwa kwesikhokelo esinokuthenjwa

• Unxibelelwano oluguquguqukayo lokudibanisa i-inverter

• Inkxaso kwiinkqubo zokuhlala zesigaba esinye kunye nesigaba esahlulweyo

Endaweni yokunciphisa ukuveliswa kwelanga ngokungaboniyo, le ndlela ivumelauhlengahlengiso olutshintshatshintshayongokusekelwe kwimfuno yokwenyani yasekhaya.

Amaqhinga aqhelekileyo oLawulo lokuHamba koMbane okuchasene nokuBuya kweNdlela

Ulawulo Lokuthumela Ngaphandle Olungadingi Kuthunyelwa Ngaphandle

Isiphumo se-inverter siyalungiswa ukuze ukuthunyelwa kwegridi kuhlale kukufutshane okanye kufikelele ku-zero. Le ndlela isetyenziswa kakhulu kwiindawo ezinemigaqo-nkqubo yegridi engqongqo.

Ukunciphisa Amandla Anamandla

Endaweni yomda omiselweyo, i-inverter output ihlengahlengiswa rhoqo ngokusekelwe kumlinganiselo wegridi wexesha langempela, nto leyo ephucula ukusebenza kakuhle kokuzisebenzisa.

Ulungelelwaniso lweHybrid PV + Ugcino

Kwiinkqubo ezineebhetri, amandla angaphezulu anokuthunyelwa kwindawo yokugcina ngaphambi kokuba kuthunyelwe kwamanye amazwe, apho imitha yamandla isebenza njengendawo yokubangela ukuba kuphume amandla.

Kuzo zonke iimeko,impendulo yexesha langempela evela kwindawo yoqhagamshelo lwegridikubalulekile ekusebenzeni okuzinzileyo nokuthobela imithetho.

Izinto ekufuneka ziqwalaselwe xa kufakelwa: Apho kufuneka kubekwe khona imitha

Ukuze ufumane ulawulo oluchanekileyo lokuhamba kwamandla oluchasene nokubuyela umva:

• Imitha yamandla kufuneka ifakwephezulu kwayo yonke imithwalo yendlu

• Umlinganiselo kufuneka wenziweIcala le-ACkwi-interface yegridi

• Ii-CT clamps mazifake ngokupheleleyo umqhubi oyintloko

Ukubekwa ngendlela engafanelekanga—njengokulinganisa kuphela imveliso ye-inverter okanye imithwalo nganye—kuya kubangela ukubhaqwa kokuthunyelwa ngaphandle okungathembekanga kunye nokuziphatha okungazinzanga kolawulo.

Izinto Eziqwalaselwayo Ngokusetyenziswa Kwabo Badibanisi NeeProjekthi Zamandla

Kwizakhiwo ezinkulu zokuhlala okanye ukufakelwa okusekelwe kwiprojekthi, ulawulo lokuhamba kombane oluchasene nokubuyela umva luba yinxalenye yoyilo olubanzi lwenkqubo.

Izinto ezibalulekileyo ekufuneka uziqwalasele ziquka:

• Uzinzo lonxibelelwano phakathi kwemitha kunye ne-inverter

• Ubuchule bolawulo lwendawo ngaphandle konxibelelwano lwelifu

• Ukwanda kokufakwa kwiindawo ezininzi

• Ukuhambelana neempawu ezahlukeneyo ze-inverter

Abavelisi bathandaU-OWON, ngeemveliso zokulinganisa amandla ezikrelekrele ezizinikeleyo ezifana ne-PC321, zibonelela ngezixhobo zokulinganisa ezinokulungiswa kwiinkqubo zamandla zokuhlala, zorhwebo, kunye neenkqubo zamandla ezisekelwe kwiprojekthi ezifuna ulawulo oluthembekileyo lokuthumela ngaphandle.

Isiphelo: Umlinganiselo ochanekileyo sisiseko sokuhamba kwamandla okuchasene nokubuyela umva

Ulawulo lokuhamba kombane oluchasene nokubuyela umva alusekho ukhetho kwiimarike ezininzi zelanga ezihlala abantu. Ngelixa ii-inverters zisenza izenzo zolawulo,iimitha zamandla ezikrelekrele zibonelela ngesiseko sokulinganisa esibalulekileyoevumela ukusebenza okukhuselekileyo, okuthotyelwayo, nokusebenzayo.

Ngokuqonda apho kwaye njani ukujika kombane ngasemva kubonwa—kwaye ngokukhetha izixhobo zokulinganisa ezifanelekileyo—abanini bezindlu kunye nabayili beenkqubo banokugcina ukuhambelana kwegridi ngaphandle kokubeka emngciphekweni ukusetyenziswa kwamandla elanga.

Ubizo Lokwenza Isenzo

Ukuba uyila okanye usebenzisa iinkqubo zelanga zasekhaya ezifuna ulawulo lokuhamba kwamandla oluchasene nokubuyela umva, ukuqonda umaleko wokulinganisa kubalulekile.
Hlola indlela iimitha zamandla ezikrelekrele ezisekelwe kwi-clamp ezifana ne-OWON's PC321 ezinokuxhasa ngayo ukujonga ngokuchanekileyo icala legridi kunye nolawulo lwexesha langempela kufakelo lwe-PV lwanamhlanje.
