Isingeniso: I-Rise of Balcony PV kanye ne-Reverse Power Challenge
Uguquko lwembulunga yonke olubheke ekukhishweni kwekhabhoni lubhebhezela uguquko oluthulile kumandla okuhlala: amasistimu e-balcony photovoltaic (PV). Kusukela "kuzitshalo zamandla amancane" kuyo yonke imizi yaseYurophu kuya ezimakethe ezisafufusa emhlabeni wonke, i-balcony PV inika abanikazi bezindlu amandla okuba abakhiqizi bamandla.
Kodwa-ke, lokhu kwamukelwa okusheshayo kwethula inselele ebalulekile yobuchwepheshe: ukuhlehla kwamandla okugeleza. Uma isistimu ye-PV ikhiqiza ugesi omningi kunalowo osetshenziswa yindlu, amandla angaphezu kwamandla angageleza abuyele kugridi yomphakathi. Lokhu kungadala:
- Ukungaqini Kwegridi: Ukushintshashintsha kwamandla kagesi okuphazamisa ikhwalithi yamandla endawo.
- Izingozi Zokuphepha: Izingozi zabasebenzi basensimini okungenzeka bangalindeli amasekhethi abukhoma ukusuka ezansi nomfula.
- Ukungathobeli Umthetho: Izinsiza eziningi ziyakwenqabela noma zijezise ukungena ngemvume okungagunyaziwe kugridi.
Kulapho i-Reverse Power Protection Solution ehlakaniphile, egxile kudivayisi yokuqapha enembayo njenge-ZigBee Power Clamp, iba yinto esemqoka ohlelweni oluphephile, oluthobelayo, nolusebenza kahle.
Isixazululo Esiyinhloko: Indlela Uhlelo Lokuvikela Amandla Oluhlehlayo lusebenza ngayo
Isistimu yokuvikela amandla ehlehlayo iyiluphu ehlakaniphile. IImitha ye-ZigBee Power Clampisebenza “njengamehlo,” kuyilapho isango elixhunyiwe nesilawuli se-inverter sakha “ubuchopho” obuthatha isinyathelo.
Umgomo Wokusebenza Ngamafuphi:
- Ukuqapha Kwesikhathi Sangempela: I-clamp yamandla, njengemodeli ye-PC321, ikala ngokuqhubekayo inkomba kanye nobukhulu bokugeleza kwamandla endaweni yokuxhuma igridi ngamasampula anesivinini esikhulu. Ilandelela amapharamitha angukhiye afana ne-Current (Irms), Voltage (Vrms), kanye namandla asebenzayo.
- Ukutholwa: Ibona ngokushesha lapho amandla eqala ukugelezakusukaikhayatoigridi.
- Isiginali Nokulawula: I-clamp idlulisa le datha ngephrothokholi ye-ZigBee HA 1.2 kusango lokuzenzakalela kwasekhaya elihambisanayo noma uhlelo lokuphatha amandla. Isistimu ibe isithumela umyalo ku-inverter ye-PV.
- Ukulungiswa kwamandla: I-inverter inciphisa amandla ayo okukhiphayo ngokunembile ukuze ifane nokusetshenziswa kwekhaya ngokushesha, isuse noma yikuphi ukugeleza okuhlehlayo.
Lokhu kudala uhlelo lwe-"Zero Export", okuqinisekisa ukuthi amandla elanga asetshenziswa endaweni.
Izici Ezibalulekile Ongazibheka Kusixazululo Sokuqapha Ikhwalithi Ephezulu
Lapho ukhetha idivayisi yokuqapha eyinhloko yamaphrojekthi akho e-PV e-balcony, cabangela lezi zici zobuchwepheshe ezibalulekile ngokusekelwe kumakhono e-PC321 Power Clamp.
Imininingwane Yobuchwepheshe Ngokubuka nje:
| Isici | Ukucaciswa nokuthi Kungani Kubalulekile |
|---|---|
| I-Wireless Protocol | I-ZigBee HA 1.2 - Inika amandla ukuhlanganiswa okungenamthungo, okujwayelekile nezinkundla ezinkulu zokulawulwa kwekhaya elihlakaniphile namandla okulawula okuthembekile. |
| Ukunemba Okulinganiselwe | < ±1.8% yokufunda - Ihlinzeka ngedatha enokwethenjelwa ngokwanele ukwenza izinqumo ezinembile zokulawula nokuqinisekisa ukuthekelisa okuyiziro kweqiniso. |
| Ama-Current Transformers (CT) | Izinketho ze-75A/100A/200A, Ukunemba < ± 2% - Iguquguqukayo ngosayizi abahlukene bomthwalo. I-plug-in, ama-CTs anekhodi enemibala avimbela amaphutha ezintambo kanye nesikhathi sokufakwa kwe-slash. |
| Ukuhambisana Kwesigaba | I-Single & 3-phase systems - Isebenza ngezindlela eziningi ngezinhlelo zokusebenza ezahlukene zokuhlala. Ukusetshenziswa kwama-CTs angu-3 esigabeni esisodwa kuvumela ukugcwaliswa kwemininingwane yomthwalo. |
| Amapharamitha Akalwa Kakhiye | Yamanje (Irms), Voltage (Vrms), Amandla Asebenzayo & Amandla, Amandla Asebenzayo Namandla - Idathasethi ebanzi yokuqonda okugcwele kwesistimu nokulawula. |
| Ukufakwa Nokuklama | I-DIN-Rail Ehlangene (86x86x37mm) - Ilondoloza isikhala kumabhodi okusabalalisa. Ilula (435g) futhi kulula ukuyifaka. |
Ngaphandle Kweshidi Elikhethekile:
- Isiginali Ethembekile: Inketho ye-antenna yangaphandle iqinisekisa ukuxhumana okuqinile ezindaweni zokufaka eziyinselele, okubalulekile ku-loop yokulawula ezinzile.
- I-Proactive Diagnostics: Ikhono lokuqapha amapharamitha afana Amandla Asebenzayo angasiza ekuhlonzeni impilo yesistimu iyonke kanye nekhwalithi yamandla.
Imibuzo Evame Ukubuzwa (FAQ) Yabasebenzi
Q1: Isistimu yami isebenzisa i-Wi-Fi, hhayi i-ZigBee. Ngingakwazi ukusebenzisa lokhu?
A: I-PC321 yakhelwe i-ZigBee ecosystem, enikezela ngenethiwekhi ye-mesh ezinzile futhi enamandla aphansi elungele izinhlelo zokusebenza zokulawula ezibalulekile njengokuvikela amandla ahlehlayo. Ukuhlanganisa kufinyelelwa ngesango elihambisana ne-ZigBee , elingase lidlulisele idatha kungxenyekazi yakho yamafu.
Q2: Uhlelo luhlangana kanjani ne-PV inverter yokulawula?
A: I-clamp yamandla ngokwayo ayilawuli i-inverter ngokuqondile. Ihlinzeka ngedatha yesikhathi sangempela ebalulekile kusilawuli esinengqondo (engaba yingxenye yesango lokuzenzakalela kwekhaya noma isistimu yokuphatha amandla ezinikele). Lesi silawuli, lapho sithola isignali "yokugeleza kwamandla ahlehlayo" kusukela ku-clamp, sithumela umyalo ofanelekile "wokunqanda" noma "ukunciphisa okukhiphayo" ku-inverter ngokusebenzisa isixhumi esibonakalayo esisekelwayo (isb, i-Modbus, i-HTTP API, ukuthintana owomile).
Q3: Ingabe ukunemba kwanele ekukhokhisweni kwensiza ebophezela ngokusemthethweni?
IMP: Cha. Le divayisi yakhelwe ukuqapha nokulawula izinhlelo zokusebenza, hhayi ukukhokhiswa kwe-utility-grade. Ukunemba kwayo okuphezulu (<±1.8%) ilungele indlela yokulawula nokunikeza idatha yokusetshenziswa okuthembeke kakhulu kumsebenzisi, kodwa ayinazo izitifiketi ezisemthethweni ze-MID noma ze-ANSI C12.1 ezidingekayo ukuze kulinganiswe imali engenayo esemthethweni.
Q4: Iyini inqubo yokufaka ejwayelekile?
A:
- Ukukhweza: Vikela iyunithi eyinhloko kuloliwe we-DIN ebhodini lokusabalalisa.
- Ukufakwa kwe-CT: Yehlisa isistimu. Bopha ama-CT anamakhodi anemibala eduze kwemigqa yokuphakelwa kwegridi eyinhloko.
- I-Voltage Connection: Xhuma iyunithi ku-voltage kalayini.
- Ukuhlanganiswa Kwenethiwekhi: Bhangqa idivayisi nesango lakho le-ZigBee ukuze uthole ukuhlanganiswa kwedatha nokulawula ukusethwa kwe-logic.
