Ifotovoltaic inarter engaphandle

Intshayelelo Intshayelelo
I-Inverter engaphandle kwe-PV sisixhobo sokuguqula amandla esipela-khupha i-DC ye-DC kwaye emva koko ixhamle ngamandla angama-220v i-AC i-In Anversi Pidge Rucet Puidges Poidge.
Njengangeembazana eziqhagamshelwe zegridi, i-rid-gerid offir-ardhers ifuna ukusebenza kakuhle, ukuthembeka okuphezulu, kunye noluhlu olubanzi lwe-DC ye-DC. Kwiinkqubo zamandla e-PV eziphakathi kunye nezinkulu, iziphumo ze-inverter kufuneka zibe yi-sinsusidal wave ene-distortion ephantsi.

Intsebenzo kunye neempawu

I-10, igalelo lokubuyela umva koQhagamshelo, igalelo lokukhusela ukuPhakanyiswa kweMpahla, iPensolliction Treature, Iziphumo zokuKhuselwa kwe-OverVoltiment, Iziphumo zokuLawulwa kweMpahla, ukhuseleko lwequbuliso kunye nenye imisebenzi yokhuseleko.

Iiparamitha ezibalulekileyo zobugcisa zegridi engaphandle
Xa ukhetha i-inverter engaphandle kwegridi, ngaphandle kokunikela ingqalelo kwimveliso yemveliso, kukho iiparamitha ezininzi ezobuchwephesha ezibaluleke kakhulu, zingamandla okuphuma, ukuguqula ixesha, ixesha lokutshintsha, njl. Ukukhethwa kwezi paramitha kunefuthe elikhulu kwimfuno yombane yomthwalo.
1) I-Voltage yeNkqubo:
Kungumvuzo wepakethi yebhetri. I-infting voltage ye-inverter engaphandle ye-Grid kunye nevolomu yemveliso yomlawuli iyafana, ke xa uyila kwaye ukhethe imodeli, nikela ingqalelo ukugcina okufanayo nomlawuli.
2) INKONZO YOKUGQIBELA:
Inkcazo yamandla e-Everter Exhumayo ineentlobo ezimbini, iyunithi yi-VA, le yindawo yokubonisa iMark, elona candelo likhutshiweyo linokufuna ukuphindaphinda i-rids , eyona nto iphambili yi-0.8, eyona ndlela isebenzayo yamandla angama-400w, oko kukuthi, unokuqhuba umthwalo we-400w, onjengezikhali zombane, i-SEFFES, njl.; Okwesibini yinkcazo yamandla esebenzayo, iyunithi i-w, njenge-5000w engaphandle kwe-Grid Anger, elona gama lisebenzayo li-5000w.
I-3) Amandla e-Deak:
Kwinkqubo ye-PV engaphandle kwegridi, iimodyuli, iibhetri, imithwalo yenza inkqubo yombane, amandla e-inverter, igqitywe ngumthwalo, iipowuni ezifana ne-pumputer, i Ukuqala kwamandla ngamaxesha angama-3-5 Amandla aqingqiweyo, ke i-Inverter ye-Grid Grid ineemfuno ezizodwa zokulayisha ngaphezulu. Amandla e-Peak ngumthamo wokugcwala i-inverter yegridi.
I-inverter ibonelela ngamandla okuqala kumthwalo, ngokuyinxenye ukusuka kwibhetri okanye kwimodyuli ye-PV, kwaye okugqithisileyo kubonelelwa ngamandla alondolozo lwamandla ngaphakathi kwi-inverter - amachaphaza kunye nabaxhasi. Amandla kunye nabaxhasi bangamalungu omandla ogcino, kodwa umahluko yile yokuba amandla anika amandla agcina amandla ombane ngendlela yentsimi yombane, kunye namandla amakhulu eCapaci, amandla amaninzi anokugcina. Izikhuselo, kwelinye icala, zigcina amandla ngendlela yemagnethi. Owona mkhulu wokuphelelwa kwemagnethi ye-Imprekshini, kokukhona ukuya phambili, kunye namandla amaninzi anokugcinwa.
4) Ukusebenza kwempumelelo:
Ukusebenza kwe-Gridionation ye-Off iquka iinkalo ezimbini, enye isebenza kakuhle kumatshini ngokwayo, kwisekethe i-ingadi ye-ingadi ye-incerid inzima, ukuze iqhubeke iphantsi kwe-inverter-qho edibeneyo kune-interter exhunyiweyo, ngokubanzi Phakathi kwe-80-90%, ngakumbi amandla e-Inverter Matshini, ukuThekwa kwe-frequency ngaphandle kokusebenza ngempumelelo kwe-frequency ephezulu, ukuphakama kwenkqubo Ukusebenza kwevolthi kuyaphezulu. Okwesibini, ukusebenza kakuhle kwebhetri kunye nokukhupha, olu luhlobo lwebhetri lunobudlelwane, xa i-Photovlaic Stylench kunye ne-Photonoltaise Synchronsise, ifotovoltaic inokubonelela ngokungqalileyo umthwalo oza kuwusebenzisa, ngaphandle kwemfuneko yokuguqula ibhetri.
5) Ixesha lokutshintsha:
Inkqubo yegridi engekho mgqomo, kukho i-PV, ibhetri, ukusebenzisa iindlela ezintathu, tshintshela kwimowudi yokusetyenziswa, kukho ixesha lokutshintsha, ixesha lokutshintsha kwe-elektroniki lisebenzisa i-10 milliseconds, Iikhompyuter zedesktop aziyi kuvalwa, ukukhanya akuyi kulunga. Abanye abantu abangamamkeli begridi badluliselwa ngokudlulisela ukutshintshela, ixesha linokuba ngaphezulu kwe-20 milliseconds, kunye nekhompyuter yedesktop inokuvala okanye iqale kwakhona.
