Ukulinganisa Ukuthunyelwa Kwamanye Amazwe Ngaphandle Okungenanto: Ibhulorho Ebalulekileyo Phakathi Kwamandla Elanga Nozinzo Lwegridi

Ukwamkelwa ngokukhawuleza kwamandla elanga asasazwayo kuvelisa umngeni obalulekileyo: ukugcina uzinzo lwegridi xa amawaka eenkqubo enokondla amandla angaphezulu kwinethiwekhi. Ngoko ke, imitha yokuthumela ngaphandle kwe-zero iguqukele ekubeni yindlela ekhethekileyo ukuya kwimfuneko yokuthobela umthetho. Kwabo badibanisa amandla elanga kwezorhwebo, abaphathi bamandla, kunye nee-OEM ezikhonza le marike, ukusebenzisa izisombululo eziqinileyo nezithembekileyo zokuthumela ngaphandle kwe-zero kubalulekile. Esi sikhokelo sinika ulwazi olunzulu ngomsebenzi, uyilo, kunye nemigangatho yokukhetha yeenkqubo zemitha yokuthumela ngaphandle zero ezisebenzayo.

"Isizathu": Uzinzo lweGrid, ukuThotyelwa kweMithetho, kunye neNgqiqo yezoqoqosho

Imitha yokuthumela ngaphandle yelanga engu-zero sisixhobo sokukhusela igridi. Umsebenzi wayo ophambili kukuqinisekisa ukuba inkqubo ye-photovoltaic (PV) isebenzisa onke amandla azenzele wona kwindawo, ithumela ngaphandle umbane ongu-zero (okanye umbane olinganiselweyo) ngqo kwisixhobo sombane.

• Ukunyaniseka kweGrid: Ukuhamba kwamandla okubuyela umva okungalawulwayo kunokubangela ukunyuka kwamandla ombane, kuphazamise izicwangciso zokukhusela igrid endala, kwaye kuthomalalise umgangatho wamandla kuyo yonke inethiwekhi yasekuhlaleni.
• Umqhubi Olawulayo: Iinkonzo zombane kwihlabathi liphela ziya ngokuya ziyalela ukuba kungabikho mitha yokuthumela ngaphandle kofakelo olutsha, ingakumbi phantsi kwezivumelwano zonxibelelwano ezilula ezithintela imfuneko yeekhontrakthi zerhafu ezintsonkothileyo.
• Ukuqinisekiswa Kwezorhwebo: Kumashishini, kususa umngcipheko wezohlwayo zokuthunyelwa kwamanye amazwe kwigridi kwaye kwenza kube lula imodeli yezoqoqosho yotyalo-mali lwelanga ukuze kongiwe ukuzisebenzisa.

"Indlela": Ubuchwepheshe kunye noYilo lweNkqubo

Ulawulo olusebenzayo lokuthumela ngaphandle olungenanto luxhomekeke kumlinganiselo wexesha langempela kunye ne-feedback loop.

1. Ukulinganisa ngokuchanekileyo: Ukuchaneka okuphezulu,imitha yamandla ebhekisa kwicala elibini(njengemitha yokuthumela ngaphandle engenazo i-phase 3 kwiindawo zorhwebo) ifakwe kwindawo yegridi ye-common coupling (PCC). Ihlala ilinganisa ukuhamba kwamandla nge-net awareness ngolwazi lwecala.
2. Unxibelelwano olukhawulezayo: Le mitha idlulisela idatha yexesha langempela (ngesiqhelo ngeModbus RTU, MQTT, okanye SunSpec) kumlawuli we-solar inverter.
3. Ukuthintela okuDynamic: Ukuba inkqubo iqikelela ukuthunyelwa ngaphandle (amandla acocekileyo asondela ku-zero kwicala lokungenisa), inika imiqondiso kwi-inverter ukuba inciphise ukuphuma. Olu lawulo lwe-closed-loop lwenzeka kwizithuba ezingaphantsi kwemizuzwana.

Ukuqonda ukuPhunyezwa: Ukufakelwa kweeNtambo kunye nokuHlanganisa

Umzobo wocingo lwemitha yokuthumela ngaphandle oqhelekileyo ubonisa imitha njenge-node ebalulekileyo phakathi kobonelelo lweenkonzo kunye nephaneli yokusasazwa kwesiza esiphambili. Kwinkqubo yezigaba ezi-3, imitha ijonga zonke ii-conductors. Into ebalulekileyo likhonkco lonxibelelwano lwedatha (umz., intambo ye-RS485) ehamba ukusuka kwimitha ukuya kwi-inverter. Ukusebenza kakuhle kwenkqubo kuxhomekeke kancinci kwidayagram yocingo ebonakalayo kodwa ngakumbi kwisantya, ukuchaneka, kunye nokuthembeka kolu tshintshiselwano lwedatha.

Ukukhetha iSiseko esiLungileyo: Uthelekiso lweSisombululo sokuMeta

Ukukhetha isisombululo esifanelekileyo sokulinganisa kubaluleke kakhulu. Apha ngezantsi kukho uthelekiso lweendlela eziqhelekileyo, olugxininisa inkqubela phambili kwizisombululo ezidibeneyo nezisebenza nge-IoT.

Ingcaciso yoKhetho oluPhambili:
Kwabo badibanisi beenkqubo kunye nabavelisi bezixhobo, ukukhetha iSisombululo 3 (i-Integrated Smart Meter) kubonisa indlela eya ekuthembekeni okukhulu, ukusetyenziswa kwedatha, kunye nokugcinwa lula. Iguqula icandelo lokulinganisa elibalulekileyo ukusuka "kwibhokisi emnyama" ukuya "kwindawo yedatha," ibeka isiseko sokwandiswa kolawulo lwamandla kwixesha elizayo njengolawulo lomthwalo okanye ukuhlanganiswa kwebhetri.

I-Owon PC321: Isiseko Sokuqonda Esikrelekrele Esenzelwe Ulawulo Oluthembekileyo Lokuthumela Ngaphandle

Njengomvelisi weemitha zamandla ezikrelekrele, u-Owon uyila iimveliso ezifana neI-PC321 Power Clamp enezigaba ezintathukunye neenkcukacha ezihlangabezana neemfuno ezibalulekileyo zecala lokulinganisa kwinkqubo yokuthumela ngaphandle engenalo:

• Isantya Esiphezulu, Umlinganiselo Ochanekileyo: Ibonelela ngomlinganiselo wamandla asebenzayo okwenyani, okuphela kwento ethembekileyo yokufaka iluphu yokulawula. Ukuchaneka kwayo okulinganisiweyo kuqinisekisa ulawulo oluchanekileyo.
• Ukuhambelana kweSigaba eSithathu kunye neSigaba esaHlukileyo: Ixhasa ngokwendalo iinkqubo zesigaba esi-3 kunye nesigaba esaHlukileyo, ezigubungela ulungelelwaniso olukhulu lwe-voltage yorhwebo lwehlabathi.
• Ii-Flexible Integration Interfaces: Nge-ZigBee 3.0 okanye ii-optional open protocol interfaces, i-PC321 inokusebenza njenge-self-standalone sensor ebika kwi-cloud EMS okanye njengomthombo wedatha osisiseko wabalawuli abakhelwe ngamaqabane e-OEM/ODM.
• Ayinangxaki ekusetyenzisweni: Ii-transformers zangoku eziqhekekileyo (ii-CT) zivumela ukufakwa okungaphazamisiyo, nto leyo enciphisa kakhulu umngcipheko kunye neendleko zokufakelwa kwakhona iiphaneli zombane eziphilayo—inzuzo ephambili kuneemitha zemveli.

Imbono yoBugcisa yabaHlanganisi:
Cinga nge-PC321 "njengelungu leemvakalelo" lenkqubo yokuthumela ngaphandle engenazo. Idatha yayo yokulinganisa, eyondliwa nge-interfaces eziqhelekileyo kwi-control logic (enokuhlala kwi-inverter ephucukileyo okanye kwi-gateway yakho), idala inkqubo ephendulayo, ecacileyo, nethembekileyo. Olu lwakhiwo oludibeneyo lubonelela abahlanganisi beenkqubo ngokuguquguquka okukhulu kunye nolawulo.

Ngaphandle kweZero Export: Uguquko oluya kuLawulo lweMandla oluHlakaniphileyo

Ukulinganisa ngaphandle kwe-zero yindawo yokuqala, hayi isiphelo, solawulo lwamandla olukrelekrele. Iziseko ezifanayo zokulinganisa ngokuchanekileyo zinokuguquka ngaphandle kokuphazamiseka ukuze zixhase:

• Ulungelelwaniso loMthwalo oDynamic: Ukuvula ngokuzenzekelayo imithwalo elawulekayo (iitshaja ze-EV, izifudumezi zamanzi) ngexesha lokugqithisa okuqikelelweyo kwelanga.
• Ukuphucula Inkqubo Yokugcina: Ukuqondisa ukutshaja/ukukhupha ibhetri ukuze isebenzise kakhulu ngelixa kulandelwa imida yokuthumela ngaphandle.
• Ukulungela Iinkonzo zeGrid: Ukubonelela ngemitha echanekileyo kunye nojongano olulawulekayo olufunekayo ukuze kubekho inxaxheba kwixesha elizayo kwiinkqubo zempendulo yemfuno okanye ze-microgrid.

Isiphelo: Ukuguqula ukuThotyelwa kweMithetho kube yiNzuzo yoKhuphiswano

Kubathengisi abathengisa ngobuninzi, abadibanisi beenkqubo, kunye nabavelisi abafuna ubudlelwane behardware, izisombululo zokuthumela ngaphandle azikho zimele ithuba elikhulu lemarike. Impumelelo ixhomekeke ekuboneleleni okanye ekudibaniseni izisombululo ezingaqinisekisi nje kuphela ukuthotyelwa kwemithetho kodwa zikwadala ixabiso ledatha yexesha elide kumthengi wokugqibela.

Xa kuvavanywa ixabiso lemitha yokuthumela ngaphandle elingenanto, kufuneka libekwe ngaphakathi kweendleko ezipheleleyo zobunini kunye nokunciphisa umngcipheko. Ixabiso lesisombululo esisekelwe kwiimitha ze-IoT ezithembekileyo ezifana ne-PC321 lilele ekuphepheni izohlwayo zokuthobela imithetho, ukunciphisa iingxabano zokusebenza, kunye nokuvula indlela yokuphucula kwixesha elizayo.

I-Owon inika izikhokelo zokudibanisa ubuchwepheshe ezineenkcukacha kunye namaxwebhu e-API kwinqanaba lesixhobo kubahlanganisi beenkqubo kunye namaqabane e-OEM.
