1. Uqwalaselo lweProjekthi

Le projekthi, ekwindawo ephambili yokhenketho lwaselunxwemeni lwaseMaldives, ijongana nemfuno yombane ekhulayo evela kumashishini angqongileyo aqhutywa kukukhula ngokukhawuleza kweshishini lezokhenketho. La mashishini ahlala ejongene nemiba efana nombane onganeleyo wegridi kunye nokucinywa kombane ngequbuliso. Le projekthi isebenzise inkqubo yokugcina amandla e-135kW/261kWh edityaniswe negridi exutyiweyo kunye ne-off-grid. Isebenza phantsi komzekelo "wokuzivelisela ngokwakho, kunye nombane ogqithisileyo ogciniweyo", ivumela ukutshintsha okungenamthungo phakathi kweendlela ezidityaniswe negridi kunye ne-off-grid, isombulula ngokupheleleyo ukunqongophala kombane kwaye iqinisekise ukusebenza okuqhelekileyo kwamashishini asekuhlaleni.

2. Iinkcukacha zeProjekthi

Isicelo se2.1

IMaldives ityebile kwimithombo yelanga, kwaye indawo yeprojekthi inokukhanya kwelanga okwaneleyo minyaka le, nto leyo eyenza ukuba ibe yindawo efanelekileyo yokwakha inkqubo yokugcina amandla e-photovoltaic. Le projekthi iseka i-microgrid "ye-PV + yokugcina amandla okuphola ngolwelo" ukubonelela abathengisi ngombane ozinzileyo, osebenza imini nobusuku. Ifanelekile kakuhle kwimozulu yaselwandle yasekuhlaleni, inciphisa ukuxhomekeka ekuveliseni umbane wedizili, kwaye ihambelana nesicwangciso sophuhliso oluluhlaza.

2.2 Umthamo oFakelweyo

Le projekthi inenkqubo ye-PV ye-135 kWp kunye nenkqubo yokugcina enegunya elilinganisiweyo le-135 kW kunye nomthamo wokugcina we-261 kWh. Isebenzisa iipakethi zebhetri ze-lithium iron phosphate (LiFePO4), le nkqubo iyahlangabezana neemfuno zombane zemihla ngemihla zabathengisi ngelixa igcina umthamo wokugcina ogqithisileyo ukuze ijongane namaxesha okhenketho aphezulu kunye nokuphazamiseka kwegridi.

2.3 Izixhobo ezingundoqo

Ikhabhinethi yokugcina amandla edibeneyo epholisiweyo ngolwelo: Ikhabhinethi enye engaphandle idibanisa izixhobo eziphambili ezinereyithingi yokhuseleko ye-IP55 kunye nokumelana nokugqwala kwebanga le-C4 ukumelana nemozulu enetyuwa eninzi kunye nomswakama ophezulu. Uyilo lwayo oluncinci lufanelekile kwindawo encinci efumaneka elunxwemeni.

Iyunithi yokudibanisa i-Photovoltaic-Storage Inverter: Ngamandla alinganisiweyo angama-135 kW, ixhasa ukutshintsha kwe-millisecond phakathi kweendlela ezibotshelelwe kwigridi kunye ne-off-grid kwaye inomlawuli we-MPPT owakhelwe ngaphakathi osebenza kakuhle ukuqinisekisa ukusebenza kakuhle kokuveliswa kombane kwenkqubo ye-photovoltaic.

Inkqubo yebhetri yeLithium Iron Phosphate (LiFePO₄): Umthamo uwonke we-261 kWh, usebenzisa iiseli ze-314Ah. Isebenza ixesha elide kwaye ikhuselekile kakhulu, inika isiqinisekiso samandla angundoqo ekusebenzeni kwenkqubo ngaphandle kwegridi.

Inkqubo yoLawulo loBushushu obuQhoboshelweyo ngoLwelo: Ixhotyiswe ngeyunithi yokupholisa ulwelo echanekileyo ye-5 kW esebenzisa ubuchwepheshe be-PFPE. Igcina umahluko wobushushu beeseli we-≤3°C ukwandisa ubomi bebhetri, kunye nokusetyenziswa okuncinci, okwenza ifaneleke kwiindawo ezishushu kakhulu zasekuhlaleni.

Inkqubo ye-Smart EMS: Ihlala ijonga ukuveliswa kombane, ukugcinwa kwawo, kunye nokusetyenziswa kwawo; ilungisa ngokuzenzekelayo iindlela zokutshaja nokukhupha umbane; ixhasa ukujonga nokugcina umbane kude; kwaye iphucula ukusebenza koqoqosho lwenkqubo.

Inkqubo yoKhuseleko loMlilo: Ixhotyiswe ngenkqubo yokucima umlilo ye-aerosol ekumgangatho ophezulu kunye nezixhobo ezahlukeneyo zokukhusela; ineedizayini ezithintela ukuqhuma, ezichasene nokufuma, kunye nezichasene nokugqwala ukuqinisekisa ukusebenza kwenkqubo ngokukhuselekileyo.

3. Iinzuzo zeProjekthi

Ukufakwa Okudibeneyo Kakhulu Nokukhawulezileyo: Izixhobo zifakelwa kwiikhabhathi ezidityanisiweyo, zilungele ukusetyenziswa kwangoko. Imijikelo yokufakelwa kunye nokuqaliswa kwayo imfutshane, ihlangabezana neemfuno zombane ezingxamisekileyo ngexesha lokhenketho oluphezulu lolwandle.

Umbane Okhuselekileyo, Othembekileyo, Nonokuguquguquka Kakhulu: Ukutshintsha kwegridi/ngaphandle kwegridi kwinqanaba le-Millisecond kusombulula ngokupheleleyo imiba yokucinywa kombane; ukupholisa ulwelo kunye noyilo olukhuselayo kakhulu zifanelekile kwiimeko zaselwandle, kunye neziqinisekiso ezininzi zamazwe ngamazwe eziqinisekisa ukusebenza ngokukhuselekileyo.

Ikrelekrele, Isebenza Kakuhle, Kwaye Isebenza Kakuhle: Ibeka phambili ukusetyenziswa kwamandla e-PV aluhlaza, inciphisa iindleko zombane kubathengisi kunye neendleko zamandla zasekuhlaleni; inkqubo ye-EMS iphucula ukusebenza, inciphisa umjikelo wotyalo-mali.

Ukuguquguquka kobukhulu bombane ukuhlangabezana neemfuno: Uyilo lwemodyuli luvumela ukwandiswa komthamo ngokongeza izixhobo; luxhasa uqhagamshelo oluhambelanayo lweekhabhathi zokugcina amandla ezininzi ukuze kuhlangatyezwane neemfuno ezikhulayo zokusetyenziswa kombane.

Iindleko ze-O&M eziNgenaNyango kwaye eziphantsi: Izixhobo ezikumgangatho wemizi-mveliso ziqinisekisa ukuthembeka okuphezulu; inkqubo yokupholisa ulwelo oluvaliweyo ifuna ulondolozo oluncinci; ixhasa ukujonga kude, inciphisa kakhulu iindleko zokusebenza kunye nokugcinwa.
