Yila inqanaba lokukhetha

-

Emva kokuhlola indlu, cwangcisa iimodyuli ze-photovoltaic ngokwendawo yophahla, ubale umthamo weemodyuli ze-photovoltaic, kwaye ngexesha elifanayo unqume indawo yeentambo kunye nezikhundla ze-inverter, ibhetri, kunye nebhokisi lokusabalalisa; izixhobo eziphambili apha ziquka iimodyuli ze-photovoltaic, i-inverter yokugcina amandla, ibhetri yokugcina amandla.

1.1Imodyuli yelanga

Le projekthi isebenzisa ukusebenza kakuhleenyeimodyuli440Wp, iiparamitha ezithile zimi ngolu hlobo lulandelayo:

Uphahla lonke lusebenzisa i-12 pv iimodyuli ezinomthamo opheleleyo we5.28kWp, zonke ezidityaniswe kwicala le-DC ye-inverter. Uyilo lophahla ngolu hlobo lulandelayo:

1.2I-Hybrid inverter

Le projekthi ikhetha inverter yokugcina amandla e-deye SUN-5K-SG03LP1-EU, iiparamitha ezithile zezi zilandelayo:

Okuinverter engumxubeineenzuzo ezininzi ezinje ngenkangeleko egqwesileyo, ukusebenza okulula, ukuzola kakhulu, iindlela ezininzi zokusebenza, ukutshintshwa kwenqanaba le-UPS, unxibelelwano lwe-4G, njl.

1.3Ibhetri yeSolar

I-Alicosolar inikeza isisombululo sebhetri (kubandakanywa ne-BMS) ehambelana ne-inverter yokugcina amandla. Le bhetri yi-low-voltage yokugcina amandla e-lithium ibhetri yamakhaya. Ikhuselekile kwaye inokwethenjelwa kwaye inokufakwa ngaphandle. Iiparamitha ezithile zezi zilandelayo:

Inqanaba lokufakela inkqubo

Umzobo wenkqubo weprojekthi yonke uboniswe ngezantsi:

2.1Ukusetha imo yokusebenza

Imodeli ngokubanzi: ukunciphisa ukuxhomekeka kwigridi kunye nokunciphisa ukuthengwa kwamandla. Kwimodi eqhelekileyo, ukuveliswa kwamandla e-photovoltaic kunikwa kuqala ukubonelela ngomthwalo, kulandelwa ukutshaja ibhetri, kwaye ekugqibeleni amandla angaphezulu angadibaniswa kwigridi. Xa ukuveliswa kwamandla e-photovoltaic kuphantsi, ukukhutshwa kwebhetri kuyongezelela.

Imo yezoqoqosho: ifanelekile kwiindawo ezinomahluko omkhulu kumaxabiso ombane ophakamileyo kunye nentlambo. Khetha imo yezoqoqosho, unokuseta amaqela amane entlawulo yebhetri ehlukeneyo kunye nexesha lokukhupha kunye namandla, kwaye ucacise intlawulo kunye nexesha lokukhutshwa, xa ixabiso lombane liphantsi, i-inverter iya kuhlawula ibhetri, kwaye xa ixabiso lombane liphezulu, ibhetri iya kukhutshwa. Ipesenti yamandla kunye nenani lemijikelezo ngeveki inokumiselwa.

Imo yokulinda: ilungele iindawo ezinegridi zamandla ezingazinzanga. Kwimo yogcino, ubunzulu bokukhupha ibhetri bunokusetwa, kwaye amandla agciniweyo angasetyenziswa xa ungekho kwigridi.

Imowudi ye-Off-grid: Kwimo ye-off-grid, inkqubo yokugcina amandla inokusebenza ngokuqhelekileyo. Ukuveliswa kwamandla e-photovoltaic kusetyenziselwa umthwalo kwaye ibhetri ihlawuliswa ngokuphindaphindiweyo. Xa i-inverter ingenzi amandla okanye ukuveliswa kwamandla akwanelanga ukusetyenziswa, ibhetri iya kukhupha umthwalo.

Ukwandiswa kwemeko yesicelo

3.1 Iskimu esinxuseneyo esingekho kwigridi

I-SUN-5K-SG03LP1-EU inokuqonda uxhulumaniso oluhambelanayo lwesiphelo esiqhagamshelwe kwigridi kunye nesiphelo se-off-grid. Nangona amandla ayo azimeleyo eyi-5kW kuphela, iyakwazi ukubona umthwalo ongekho kwigridi ngoqhagamshelo olunxuseneyo, kwaye inokuthwala imithwalo yamandla aphezulu (ubuninzi obungama-75kVA)

3.2 Ukugcinwa kwe-Photovoltaic kunye ne-Diesel Microgrid Solution

Isisombululo se-optical storage diesel micro-grid isisombululo sinokudibaniswa kwimithombo yamandla e-4, i-photovoltaic, ibhetri yokugcina amandla, i-diesel generator kunye negridi, kwaye okwangoku sesinye sezona zisombululo zombane ezipheleleyo nezithembekileyo ezikhoyo; Kwimeko yokulinda, umthwalo uxhatshazwa kakhulu yi-photovoltaic + ukugcinwa kwamandla; xa umthwalo uguquguquka kakhulu kwaye amandla okugcina amandla aphelile, i-inverter ithumela uphawu lokuqala kwi-diesel, kwaye emva kokuba idizili ishushu kwaye iqale, ngokuqhelekileyo inika amandla kumthwalo kunye nebhetri yokugcina amandla; Ukuba igridi yamandla isebenza ngokuqhelekileyo, ijenereyitha yedizili ikwimeko yokuvala ngeli xesha, kwaye umthwalo kunye nokugcinwa kwamandla ebhetri kunikwa amandla yigridi yamandla..

 Phawula:Inokusetyenziswa kwakhona kwimeko yokugcina i-optical kunye ne-diesel ngaphandle kokutshintsha kwegridi.

3.3 Isisombululo sokutshaja ugcino lwasekhaya lwasekhaya

Ngophuhliso kunye nokuthandwa kweshishini lezithuthi zombane, kukho izithuthi zombane ezingakumbi kwintsapho. Kukho imfuno yokutshaja ye-5-10 kilowatt-iiyure ngosuku (ngokungqinelana ne-1 kilowatt-yure inokuhamba iikhilomitha ezi-5). Umbane uyakhululwa ukuhlangabezana neemfuno zokutshaja kweisithuthi, kwaye ngexesha elifanayo ukukhulula uxinzelelo kwigridi yamandla ngexesha leeyure eziphakamileyo zokusetyenziswa kombane.

Eli nqaku lazisa nge-5kW/10kWh inkqubo yokugcina amandla ukusuka kuyilo, ukukhetha, ukufakela kunye nokugunyaziswa, kunye nokwandiswa kwezicelo zezikhululo zamandla zokugcina amandla ezindlini. Iimeko zesicelo. Ngokuqiniswa kwenkxaso yomgaqo-nkqubo kunye nokutshintshwa kweengcamango zabantu, kukholelwa ukuba iinkqubo ezininzi zokugcina amandla ziya kubonakala ngathi.
