Intshayelelo: Ukunyuka kweBalcony PV kunye neReverse Power Challenge
Ukutshintsha kwehlabathi ngokubhekiselele kwi-decarbonization kuphembelela inguqu ezolileyo kumandla okuhlala: iinkqubo ze-balcony photovoltaic (PV). Ukusuka "kwizityalo zamandla amancinci" kuzo zonke izindlu zaseYurophu ukuya kwiimarike ezivelayo kwihlabathi liphela, i-balcony PV ixhobisa abaninimzi ukuba babe ngabavelisi bamandla.
Nangona kunjalo, oku kwamkelwa ngokukhawuleza kuzisa umngeni obalulekileyo wobugcisa: ukubuya umva amandla. Xa inkqubo ye-PV ivelisa umbane omninzi kunoko kusetyenziswa yindlu, amandla angaphezulu anokuqukuqela abuyele kwigridi yoluntu. Oku kunokubangela:
- Ukungazinzi kweGridi: Ukuguquguquka kwamandla ombane okuphazamisa umgangatho wamandla wendawo.
- Iingozi zoKhuseleko: Imingcipheko yabasebenzi abangasebenziyo abangalindelanga iisekethe eziphilayo ukusuka ezantsi.
- Ukungathotyelwa kweMithetho: Izinto ezininzi eziluncedo ziyakwalela okanye zohlwaya ngokungagunyaziswanga ukungena kwigridi.
Apha kulapho iSisombululo soKhuseleko lwaMandla obukrelekrele, esigxile kwisixhobo sokubeka iliso esichanekileyo esinje ngeZigBee Power Clamp, siba yimfuneko kwinkqubo ekhuselekileyo, ethobelayo, nesebenzayo.
Isisombululo esiPhambili: Indlela iNkqubo yokuKhusela uMandla eReverse isebenza
Inkqubo yokukhusela umbane yi-loop ekrelekrele. IZigBee Power Clamp imithaisebenza "njengamehlo," ngelixa isango elidibeneyo kunye nomlawuli we-inverter wenza "ubuchopho" obuthatha isenzo.
UmGaqo wokuSebenza ngamafutshane:
- Ukubeka iliso ngexesha langempela: I-clamp yamandla, efana nemodeli ye-PC321, ngokuqhubekayo ilinganisa isalathiso kunye nobukhulu bokuhamba kwamandla kwindawo yokudibanisa igridi kunye nesampulu yesantya esiphezulu. Ilandelela iiparameters eziphambili ezifana nezangoku (Irms), iVoltage (Vrms), kunye namandla asebenzayo.
- Ukufunyanwa: Ibona ngoko nangoko xa amandla eqala ukuhambaukusukaikhayatoigridi.
- Umqondiso kunye noLawulo: I-clamp idlulisela le datha nge-protocol ye-ZigBee HA 1.2 kwisango elizenzekelayo lekhaya elihambelanayo okanye inkqubo yokulawula amandla. Inkqubo ke ithumela umyalelo kwi-inverter ye-PV.
- Uhlengahlengiso lwamandla: I-inverter inciphisa amandla ayo aphumayo ngokuchanekileyo ukuze ihambelane nokusetyenziswa kwekhaya kwangoko, isusa nakuphi na ukubuya umva.
Oku kudala inkqubo ethi "Zero Export", eqinisekisa ukuba onke amandla elanga asetyenziswa ekuhlaleni.
Iimpawu eziphambili zokuJonga kwiSisombululo sokuJonga i-High-Quality Monitoring
Xa ukhetha isixhobo sokubeka iliso esingundoqo kwiiprojekthi zakho zePV zebalcony, qwalasela ezi mpawu zibalulekileyo zobugcisa ezisekwe kubuchule bePC321 Power Clamp.
IiNgcaciso zobuGcisa ngokuJonga nje:

Ngaphandle kwePhepha eliKhethekileyo:
- Umqondiso othembekileyo: Inketho ye-antenna yangaphandle iqinisekisa unxibelelwano oluqinileyo kwiindawo zokufakela umngeni, okubaluleke kakhulu kwi-loop yokulawula ezinzile.
- I-Proactive Diagnostics: Ukukwazi ukujonga iiparamitha ezifana ne-Reactive Power inokunceda ekuxilongeni impilo yonke yenkqubo kunye nomgangatho wamandla.
Imibuzo Ebuzwa Rhoqo (FAQ) yeeNgcali
Q1: Inkqubo yam isebenzisa iWi-Fi, hayi iZigBee. Ndingayisebenzisa le nto?
A: I-PC321 yenzelwe iZigBee ecosystem, enika umnatha womnatha ozinzileyo kunye nonamandla aphantsi olungele izicelo zolawulo olubalulekileyo njengokhuseleko lwamandla abuyela umva. Udibaniso luphunyezwa ngesango elihambelana neZigBee, elinokuthi ligqithise idatha kwiqonga lakho lelifu.
I-Q2: Inkqubo idibanisa njani kunye ne-PV inverter yokulawula?
A: I-clamp yamandla ngokwayo ayilawuli i-inverter ngokuthe ngqo. Inika idatha ebalulekileyo yexesha langempela kumlawuli wengqiqo (enokuthi ibe yinxalenye yesango elizenzekelayo lekhaya okanye inkqubo yolawulo lwamandla). Lo mlawuli, xa efumana "i-reverse power flow" isignali kwi-clamp, ithumela "i-curtail" efanelekileyo okanye "ukunciphisa imveliso" umyalelo kwi-inverter nge-interface yayo exhaswayo (umzekelo, i-Modbus, i-HTTP API, uqhagamshelwano olomileyo).
I-Q3: Ngaba ukuchaneka kwanele ukubophelela ngokusemthethweni i-bill yenkonzo?
A: Hayi. Esi sixhobo senzelwe ukubeka iliso kunye nokulawula usetyenziso lwamandla, hayi ukuhlawulwa kwebakala eliluncedo. Ukuchaneka kwayo okuphezulu (<± 1.8%) igqibelele kwingqiqo yokulawula kunye nokubonelela ngedatha yokusetyenziswa okuthembekileyo kumsebenzisi, kodwa ayinayo i-MID esemthethweni okanye i-ANSI C12.1 izatifikethi ezifunekayo kwi-metering yengeniso esemthethweni.
