Idolobha lethu elizokwakhiwa ngomasipala, uhulumeni usanda kuthenga inkampani yethu isistimu yelanga engu-4MW ukuze ishaje amabhasi emgwaqeni wedolobha ngomhla ka-6, Disemba.
Isistimu yamandla elanga angaphandle kwegridi isebenzisa amaphaneli elanga ukuze iguqule amandla elanga abe ngugesi ngokukhanya, inikeze umthwalo ngeshaje yelanga nesilawuli sokukhipha, futhi ishaje ibhethri;esimweni sezulu esimnyama noma kungabikho ukukhanya, iyunithi yebhethri ngomthwalo we-DC kusilawuli sebhethri, kanye nebhethri ngqo ku-inverter ezimele, ngokusebenzisa i-inverter inverter ezimele ukuya ku-AC, ukuhlinzeka ngomthwalo we-AC.Isistimu yokukhiqiza amandla elanga engaphandle kwegridi esetshenziswa kakhulu ezindaweni ezikude ezisezintabeni, ezindaweni ezingenawo amandla, iziqhingi, iziteshi eziyisisekelo zokuxhumana kanye nezinye izindawo zohlelo lokusebenza.Uhlelo ngokuvamile lwakhiwe i-photovoltaic square array eyakhiwa i-solar cell module, i-solar charge kanye nesilawuli sokukhipha, ibhethri pack, off-grid inverter. , umthwalo we-DC kanye nomthwalo we-AC.Isikwele se-photovoltaic siguqula amandla elanga kumandla kagesi ngokukhanya, sinikeze umthwalo ngeshaje yelanga nesilawuli sokukhipha, futhi sishaje iphakethe lebhethri, ibhethri izohlinzeka ngomthwalo we-DC ngaphandle kokukhanya, kanye nebhethri. izophinde inikeze ngokuqondile i-inverter ezimele, iguqule isiguquli sibe yi-AC ukuze sinikeze umthwalo we-AC.
Izinto okufanele zicatshangelwe ekwakhiweni kwezinhlelo zamandla elanga:
1. Isetshenziswa kuphi isistimu yokuphehla amandla elanga?Siyini isimo semisebe yelanga endaweni?
2. Angakanani amandla omthwalo wesistimu?
3. Ithini i-voltage ephumayo yesistimu, i-DC noma i-AC?
4. Mangaki amahora uhlelo oludinga ukusebenza nsuku zonke?
5. Esimeni sezulu esinemvula ngaphandle kokukhanya kwelanga, zingaki izinsuku lapho uhlelo ludinga ukunikezwa kwamandla okuqhubekayo?
6. Isimo somthwalo, ukumelana okuhlanzekile, amandla noma ukuzwa kukagesi, kungakanani ukuqala kwamanje?
Ingxenye eyinhloko yesistimu yokuphehla amandla elanga ngaphandle kwegridi, kodwa futhi ingxenye ebaluleke kakhulu yohlelo, ukuguqula amandla elanga wamandla emisebe ibe amandla e-DC.Ngokuvumelana nezidingo zamandla ahlukene zomsebenzisi kanye ne-voltage, izingxenye zamaseli elanga ingenziwa ibe ukusetshenziswa okukodwa, noma izingxenye eziningana zamaseli elanga zingaxhunywa ochungechungeni (ukuze kuhlangatshezwane nezidingo zamandla kagesi) futhi ngokuhambisana (ukuze kuhlangatshezwane nezidingo zamanje), ukuze kwakhiwe uxhaxha lwamandla okuhlinzeka ngamandla amakhulu amanje.Iseli yelanga izingxenye zibonakala ngamandla athile endaweni ephakeme, impilo ende nokuthembeka okuphezulu.Esikhathini sesevisi yeminyaka engu-20, amandla okukhiphayo ehla ngokuvamile angekho ngaphezu kuka-20%.Ngokushintsha kwezinga lokushisa, amandla amanje, amandla kagesi kanye namandla ephakethe lebhethri nakho kuzoshintsha, ngakho-ke i-voltage engalungile kanye ne-coefficient yezinga lokushisa kufanele kuthathwe. kucatshangelwe ekwakhiweni kochungechunge lwezingxenye.
