Ukugcinwa kwamandla kukufumana ukuthandwa njengento ebalulekileyo kwimithombo yamandla avuselelekayo.Phakathi kweenkqubo zokugcina amandla, ugcino lwamandla orhwebo kunye noshishino kunye nokugcinwa kwamandla okusebenza zimbini izisombululo eziphawulekayo eziye zavela kwiminyaka yakutshanje.Nangona kunjalo, zineemeko ezahlukeneyo zesicelo kunye neempawu zobugcisa.Eli nqaku liza kucacisa umahluko phakathi kwezi ntlobo zimbini zeenkqubo zokugcina amandla ukusuka kwimilinganiselo emininzi.
Application Scenarios
Ukugcinwa kwamandla e-C & I ikakhulu kusetyenziswe kumandla okubonelela ngokuzimeleyo kubasebenzisi bezorhwebo kunye namashishini abandakanya iifektri, izakhiwo, amaziko edatha, njl.
Ugcino lwamandla olusetyenziswayo lusetyenziswa ikakhulu kwicala legridi.Injongo kukulungelelanisa unikezelo lwamandla kunye nemfuno, ukulawula ubuninzi begridi, kunye nokuphumeza ummiselo wencopho yentlambo.Isenokubonelela ngomthamo kunye nezinye iinkonzo zolawulo lwamandla.
Cukukhululeka
Umthamo wogcino lwamandla we-C&I uqhelekile kuluhlu lwamashumi aliqela ukuya kumakhulu ee-kilowatt-iiyure, ikakhulu kuxhomekeke kubungakanani bomthwalo womsebenzisi kunye nemfuno yoluhlu lwamaxabiso.Umthamo weenkqubo ze-C&I zomgangatho omkhulu kakhulu awugqithisi kwi-10,000 kWh.
Umthamo wogcino lwamandla okusebenza ukusuka kwiimegawathi ezininzi ukuya kwiiyure ezingamakhulu aliqela eemegawathi, ungqamanisa isikali segridi kunye neemfuno.Kwiiprojekthi ezinkulu zomgangatho wegridi, umthamo wesiza esinye unokufikelela kumakhulu eemegawathi iiyure.
Amacandelo eNkqubo
·Ibhetri
Ukugcinwa kwamandla e-C&I kufuna ixesha lokuphendula elisezantsi ngokwentelekiso.Ukuqwalasela ngokubanzi iindleko, ubomi bomjikelezo, ixesha lokuphendula kunye nezinye izinto, iibhetri ezinobuninzi bamandla njengoko zisetyenziswa kuqala.Ugcino lwamandla olusetyenziswayo lusebenzisa uxinaniso lwamandla ebhetri egxile kulawulo lwamaza.
Ngapha koko, uninzi logcino lwamandla amakhulu lukwasebenzisa iibhetri ezinoxinano lwamandla njengento ephambili.Kodwa ekubeni bafuna ukubonelela ngeenkonzo ezincedisayo zamandla, iinkqubo zebhetri zezikhululo zamandla zokugcina amandla zineemfuno eziphezulu zobomi bomjikelezo kunye nexesha lokuphendula.Iibhetri ezisetyenziselwa ukulawulwa rhoqo kunye nokugcinwa kwenkxaso kaxakeka kufuneka ukhethe uhlobo lwebhetri.
·Inkqubo yoLawulo lwebhetri (BMS)
Iinkqubo zokugcina amandla ze-C & I ezincinci kunye neziphakathi zinokubonelela ngebhetri ipakethi ngemisebenzi eyahlukeneyo yokukhusela, njengokugqithiswa, ukukhupha, ukugqithisa, ukugqithiswa, ukushisa, ukushisa okuphantsi, i-short-circuit kunye nokunciphisa okwangoku.Inokulinganisa amandla ombane wepakethi yebhetri ngexesha lenkqubo yokutshaja, qwalasela iiparamitha kwaye ubeke iliso kwidatha ngesoftware yangasemva, ukunxibelelana neentlobo ezahlukeneyo zeenkqubo zokuguqula amandla, kwaye uqhube ulawulo olukrelekrele lwenkqubo yonke yokugcina amandla.
Isikhululo samandla sogcino lwamandla sinokulawula iibhetri zomntu ngamnye, iipakethi zeebhetri kunye neentlanti zeebhetri ngendlela ecwangcisiweyo.Ngokusekelwe kwiimpawu zabo, iiparitha ezahlukeneyo kunye neemeko zokusebenza kweebhetri zingabalwa kwaye zihlalutye ukufezekisa ukulinganisa, i-alamu kunye nolawulo olusebenzayo.Oku kuvumela iqela ngalinye leebhetri ukuba livelise imveliso efanayo, ukuqinisekisa ukuba inkqubo ifezekisa eyona ndlela yokusebenza kunye nexesha elide lokusebenzisa.Oku kubonelela ngolwazi oluchanekileyo nolusebenzayo lwebhetri.Ngolawulo lokulinganisa ibhetri, ukusetyenziswa kwamandla ebhetri kungaphuculwa kakhulu kunye neempawu zokulayisha.Ngexesha elifanayo, ubomi benkonzo yeebhetri bunokwandiswa ukuze kuqinisekiswe ukuzinza, ukhuseleko kunye nokuthembeka kwenkqubo yokugcina amandla.
·Inkqubo yokulawula amandla(PCS)
Ii-inverters ezisetyenziswa kwi-C&I yogcino lwamandla zinemisebenzi elula, eyona nto iphambili ukuguqulwa kwamandla e-bidirectional, ubungakanani obuncinci, kwaye kulula ukudibanisa neenkqubo zebhetri.Umthamo unokwandiswa ngokuguquguqukayo njengoko kufuneka.Ii-inverters ziyakwazi ukuziqhelanisa noluhlu olubanzi lwe-voltage ye-150-750 volts, ukuhlangabezana nochungechunge kunye neemfuno zoxhumo oluhambelanayo lweebhetri ze-lead-acid, iibhetri ze-lithium, iibhetri zokuhamba kunye nezinye iibhetri, kunye nokufezekisa ukutshaja kunye nokukhupha unidirectional.Bangakwazi kwakhona ukuhambelana neentlobo ezahlukeneyo ze-photovoltaic inverters.
Ii-inverters ezisetyenziswa kwizikhululo zamandla okugcina amandla zineendlela zombane ezibanzi ze-DC, ukuya kuthi ga kwi-1500 volts yokusebenza komthwalo ogcweleyo.Ukongeza kumsebenzi osisiseko wokuguqula amandla, kufuneka kwakhona babe nemisebenzi elungelelanisiweyo yegridi, njengommiselo ophambili wokuphindaphinda, ukuthumela ngokukhawuleza umthombo-igridi-umthwalo, njl.
·INkqubo yoLawulo lwaMandla (EMS)
Uninzi lwe-EMS ye-C&I yenkqubo yokugcina amandla ayidingi ukwamkela ukuthunyelwa kwegridi.Imisebenzi yabo isisiseko, idinga kuphela ukwenza ulawulo lwamandla asekuhlaleni, oko kukuthi ukuxhasa ulawulo lokulinganisa ibhetri, ukuqinisekisa ukhuseleko lokusebenza, ukuxhasa impendulo ekhawulezayo ye-millisecond, kunye nokufezekisa ulawulo oludibeneyo kunye nolawulo oluphakathi lwezixhobo zokugcina amandla eziphantsi kwenkqubo.
Nangona kunjalo, ugcino lwamandla ombane oluncedo olunje ngezikhululo zamandla okugcina amandla ezifuna ukwamkela ukuthunyelwa kwegridi zineemfuno eziphezulu ze-EMS.Ukongeza kwimisebenzi esisiseko yolawulo lwamandla, kufuneka kwakhona babonelele ngonxibelelwano lwegridi yokuthumela kunye nobuchule bolawulo lwamandla kwiinkqubo zegridi ezincinci.Kufuneka baxhase iiprothokholi zonxibelelwano ezininzi, babe nonxibelelwano oluqhelekileyo lokuhambisa amandla, bakwazi ukuqhuba ulawulo lwamandla kunye nokubeka iliso kwiimeko zesicelo ezifana nokugqithiselwa kwamandla, iigridi ezincinci, kunye nolawulo lwamaza ombane, kunye nokuxhasa ukuzalisekiswa kunye nokubeka iliso kwiinkqubo ezininzi ezifana imithombo yamandla, iigridi, imithwalo, kunye nokugcinwa kwamandla.
Isazobe soku-1.Umzobo wesakhiwo senkqubo yorhwebo kunye nokugcinwa kwamandla oshishino
