1. Uqwalaselo lweProjekthi

Le projekthi ibandakanya ukuthunyelwa kwenkqubo edibeneyo yokugcina umbane ye-AC edityaniswe ne-AC kwindawo yokuthengisa umbane ye-4S yomthengi eCambodia. Ibandakanya i-inverter ye-photovoltaic ye-125kW kunye nenkqubo yokugcina umbane entsha eyongeziweyo, evumela ukusebenza okumbaxa: 'ukuzivelisela ngokwakho ukuzisebenzisa kunye nokungenisa okungaphezulu kwigridi' kunye 'namandla okugcina umbane ngaphandle kwegridi'. Uyilo lwenkqubo lujonga ngokupheleleyo iipateni zokusetyenziswa kombane komthengi (ukusetyenziswa okuqhelekileyo kwemihla ngemihla malunga ne-14.8kWh, iiyure zokusebenza ziqala ngo-8:00–20:00) kwaye ixhasa ukuthengiswa kombane ongaphezulu ukuya kuthi ga kwi-15kWh kwigridi yonke imihla.

2. Iinkcukacha zeProjekthi

isicelo

Le nkqubo isebenza ngeendlela ezimbini:

Imowudi eqhagamshelwe kwigridi:

– Imithwalo yasemini ibeka phambili amandla e-photovoltaic;

– Ukuveliswa kwe-PV engaphezulu kuqala kutshaja iibhetri zokugcina;

– Xa ibhetri itshajiwe ngokupheleleyo, amandla e-PV angaphezulu angathengiswa kwigridi (avalwe kwi-15kWh/ngosuku);

Ngexesha lasebusuku okanye xa kukho amafu, ukukhupha ibhetri kunika amandla ide i-SOC yehle ngaphantsi kwe-10%, apho inkqubo ivala khona ize itshintshele kumbane oyintloko;

Akuvumelekanga ukutshaja iibhetri ezivela kumbane ophambili.

Imo yokuLinda engekho kwiGridi:

Ngexesha lokucima kombane, inkqubo yokugcina amandla itshintshela ngokuzenzekelayo ekusebenzeni ngaphandle kwegridi ukuze inikezele ngemithwalo ebalulekileyo;

Inkqubo iyacima xa ukukhupha ibhetri kufikelela kwi-SOC < 10%, nto leyo ebangela ukuba umthwalo uqhawuke.

3. Iinzuzo zeProjekthi

Ukuphucula uQoqosho: Kuphucula ukuzivelisa nokuzisebenzisa ukuze kuncitshiswe iindleko zombane; kuxhasa ukongezwa kwemali esisigxina yemihla ngemihla ukuze kufumaneke ingeniso eyongezelelweyo.

Ukhuseleko lwaMandla: Ibonelela ngombane ongasemva ongaphandle kwegridi ngexesha lokucima kwezixhobo eziphambili, iqinisekisa ukusebenza kwexesha elifutshane kwemithwalo ebalulekileyo.

Ukucwangcisa okukrelekrele: Itshintsha ngokuzenzekelayo amaqhinga okutshaja/okukhupha ibhetri ngokusekelwe kwimida ye-SOC (10%–100%) ukuze yandise ubomi bebhetri.

Ukuhambelana okuphezulu: Iindlela zonxibelelwano ezigciniweyo zivumela ukuhlanganiswa neenkqubo ze-PV ezikhoyo kunye nezixhobo zokulinganisa igridi.

Uhlengahlengiso lweNdawo: Ingqiqo yokulawula eyenzelwe wena ngokwesiqhelo ukusetyenziswa okuphantsi kwemihla ngemihla kwabathengi (malunga ne-14.8kWh) kunye neeyure zokusebenza, okuthintela ukubonelela okugqithisileyo.
