Imisebenzi eNxulumeneyo yePV Inverter yaziswa

1.Umsebenzi ophezulu wokulandelela indawo yamandla (MPPT).

Ukulandelela indawo yamandla aphezulu (MPPT) yiteknoloji engundoqo ye-photovoltaic inverters. Ekubeni amandla okukhutshwa kwemodyuli ye-photovoltaic etshintsha ngamandla okukhanya kwelanga kunye nokushisa kwemodyuli ngokwayo, kukho indawo efanelekileyo yokusebenza, indawo ephezulu yamandla (MPP). Umsebenzi weMPPT kukwenza ukuba imodyuli ye-photovoltaic ihlale isebenza kufuphi neyona ndawo iphezulu yamandla, ngaloo ndlela ikhulisa ukusebenza kakuhle kokuveliswa kwamandla.

Ukuze ufezekise i-MPPT, i-photovoltaic inverter iya kuhlala ibona utshintsho lwangoku kunye ne-voltage yemodyuli ye-photovoltaic, kwaye ilungelelanise imeko yokusebenza ye-inverter ngokwezi nguqulelo. Ngokuqhelekileyo, i-MPPT iphunyezwa nge-DC / DC yokuguqulwa kwesiphaluka, ngokulungelelanisa umlinganiselo we-PWM we-drive signal duty ye-converter ye-DC / DC, ukwenzela ukuba ukukhutshwa kwemodyuli ye-photovoltaic ihlale igcinwe kufuphi nendawo enkulu yamandla.

2.Umsebenzi wokubeka iliso kwigridi yamandla

Umsebenzi wokubeka iliso kwigridi yamandla wenza ukuba ii-photovoltaic inverter ukujonga imeko yegridi yamandla ngexesha langempela, kubandakanywa i-voltage, i-frequency, isigaba kunye nezinye iiparameters, ukuqinisekisa ukuhambelana kunye nokuzinza kwesikhululo samandla e-photovoltaic kunye negridi yamandla. Ngokubeka iliso kwigridi, i-inverter inokulungelelanisa imveliso yayo ngexesha langempela ukulungelelanisa utshintsho kwigridi kwaye iqinisekise ukuba umgangatho wamandla uhlangabezana neemfuno zegridi. Ukongeza, umsebenzi wokubeka iliso kwigridi yamandla unokunceda abaphathi baqonde imeko yokusebenza kwegridi yamandla, bafumanise kwaye bajongane neengxaki ezinokubakho ngexesha elifanelekileyo, kwaye baqinisekise ukusebenza okuzinzileyo kwegridi yamandla.izityalo zamandla e-photovoltaic.

3.Umsebenzi wokukhusela iimpazamo

I-Photovoltaic inverter inomsebenzi opheleleyo wokukhusela impazamo yokujongana neemeko ezahlukeneyo ezingaqhelekanga ezinokuthi zenzeke kwinkqubo yokusetyenziswa kwangempela, ukukhusela i-inverter ngokwayo kunye namanye amacandelo enkqubo kumonakalo. Ezi mpawu zingaphumeleliyo ziquka:

1. Igalelo elingaphantsi kombane kunye nokhuseleko lokugqithiswa kwamandla ombane:Xa i-voltage yegalelo iphantsi okanye iphezulu kunoluhlu oluthile lombane olinganisiweyo, i-inverter iqalisa indlela yokukhusela ukukhusela umonakalo wesixhobo.
2. Ukhuseleko lwangoku:Xa umbane osebenzayo udlula umlinganiselo othile wombane olinganisiweyo, i-inverter iyayinqumla ngokuzenzekelayo isiphaluka ukuthintela umbane ogqithisileyo ekubangeleni umonakalo kwisixhobo.
3. Imveliso yokhuseleko lwesekethe emfutshane:I-inverter inomsebenzi okhawulezayo wokukhusela isiphaluka esifutshane, esinokunqumla isiphaluka ngexesha elifutshane kakhulu emva kokuba isiphaluka esifutshane senzeke, kwaye sikhusele izixhobo kwimpembelelo yesiphaluka esifutshane.
4. Ukhuseleko lwengeniso umva:Xa igalelo lichanekile kwaye i-electrode engalunganga iguqulwa, i-inverter iya kuqalisa indlela yokukhusela ukukhusela izixhobo ukuba zingonakaliswe yi-voltage reverse.
5. Ukhuseleko lombane:I-inverter inesixhobo sokukhusela umbane esakhelwe ngaphakathi, esinokukhusela izixhobo kumonakalo wombane kwimozulu yombane.
6. Ukhuseleko ngaphezulu kobushushu:I-inverter nayo inomsebenzi wokukhusela ukushisa, xa ukushisa kwangaphakathi kwesixhobo kuphezulu kakhulu, kuya kunciphisa ngokuzenzekelayo amandla okanye ukuyeka ukuthintela izixhobo ukuba zingonakaliswe ngenxa yokushisa.

Le misebenzi yokukhusela impazamo kunye iqinisekisa ukusebenza okuzinzileyo kunye nokhuseleko lweinverter yelanga . Kwisicelo esisebenzayo, umsebenzi wokukhusela impazamo ye-photovoltaic inverter ibaluleke kakhulu ekuphuculeni ukuthembeka kunye nokuzinza kwesikhululo samandla e-photovoltaic.
