I-inverter esanda kwenziwa yinkampani

I-inverter, eyaziwa nangokuthi isilawuli samandla, isilawuli samandla, siyingxenye ebalulekile yesistimu ye-photovoltaic.Umsebenzi obaluleke kakhulu we-photovoltaic inverter ukuguqula amandla e-DC akhiqizwa iphaneli yelanga ibe amandla e-AC asetshenziswa izinto zasendlini.Wonke ugesi okhiqizwe iphaneli yelanga ungathunyelwa ngokwelashwa kwe-inverter.ngokusebenzisa isekethe yebhuloho eligcwele, ngokuvamile ithatha iphrosesa ye-SPWM ngokushintshashintsha, ukuhlunga, ukukhushulwa kwamandla kagesi, njll., ukuze uthole uhlelo lwe-AC lwe-sinusoidal oluhambisana nokukhanyisa. imvamisa yokulayisha, i-voltage elinganiselwe yabasebenzisi bokugcina.Nge-inverter, ibhethri le-DC lingasetshenziswa ukunikeza amandla e-AC omshinini.

Uhlelo lokuphehla amandla eSolar AC luqukethe amaphaneli elanga, isilawuli sokushaja, i-inverter nebhethri;Isistimu yokukhiqiza amandla elanga ye-DC ayifaki i-inverter.Inqubo yokuguqula amandla kagesi e-AC abe amandla kagesi e-DC ibizwa ngokuthi ukulungiswa, isekethe eqeda umsebenzi wokulungisa ibizwa ngokuthi i-rectifier circuit, kanti idivayisi eqaphela inqubo yokulungisa eyaziwa ngokuthi idivayisi yokulungisa kabusha noma isilungisi. Ngokuhambisanayo, inqubo yokuguqula amandla kagesi e-DC abe amandla kagesi e-AC ibizwa ngokuthi i-inverter, isekethe eqeda umsebenzi wokuguqula ibizwa ngokuthi i-inverter circuit, kanye nedivayisi eqaphela inqubo yokuguqula. ibizwa ngokuthi i-inverter noma i-inverter.
Umnyombo we-inverter idivayisi iyisekhethi ye-inverter switch, umane nje uyi-inverter circuit.Isekhethi iqedela umsebenzi we-inverter ngokusebenzisa i-inverter yamandla kagesi. kulawulwa ngokushintsha isignali ye-voltage.Amasekhethi akhiqiza futhi alawule ama-pulses ajwayele ukubizwa ngokuthi i-control circuit noma i-control circuit.Isakhiwo esiyisisekelo sedivayisi ye-inverter, ngaphezu kwe-inverter circuit eshiwo ngenhla kanye ne-control circuit, nayo ine- isifunda sokuvikela, isifunda esikhiphayo, isifunda esikhiphayo, isifunda esikhiphayo nokunye.

I-inverter ephakathi nendawo ngokuvamile isetshenziswa kumasistimu aneziteshi ezinkulu zamandla e-photovoltaic (> 10kW).Amaqoqo amaningi e-photovoltaic ahambisanayo axhunywe kokokufaka kwe-DC kwe-inverter efanayo emaphakathi.Ngokuvamile, amandla amakhulu asebenzisa i-module yamandla ye-IGBT yesigaba ezintathu, amandla amancane asebenzisa ama-transistors womphumela wensimu, futhi asebenzise isilawuli sokuguqulwa kwe-DSP ukuze kuthuthukiswe ikhwalithi yamandla okukhipha ugesi, okwenza kube seduze kakhulu ne-sinusoidal wave current.Isici esikhulu kunazo zonke esiphezulu esiphezulu amandla kanye nezindleko eziphansi.Nokho, ngenxa yokufanisa uchungechunge lweqembu le-photovoltaic kanye ne-shading eyingxenye, kuholela ekusebenzeni kahle namandla okusebenza kwesistimu yonke ye-photovoltaic.Ngasikhathi sinye, ukuthembeka kokukhiqizwa kwamandla kwesistimu yonke ye-photovoltaic okuthintekayo esimweni esingesihle sokusebenza seqembu elithile leyunithi ye-photovoltaic.Isiqondiso sakamuva socwaningo ukulawulwa kokushintshashintsha kwama-vectors wendawo, kanye nokuthuthukiswa kokuxhumeka kwe-topological of inverters entsha ukuze kutholwe ukusebenza kahle okuphezulu emacaleni okulayisha ingxenye.Ku-SolarMax ( I-SowMac) i-inverter emaphakathi, ibhokisi lesixhumi esibonakalayo le-photovoltaic array lingangezwa ukuze kuqashwe uchungechunge ngalunye lochungechunge lwamaphaneli e-photovoltaic.Uma isethi yazo ingasebenzi kahle, isistimu izodlulisela ulwazi kusilawuli esikude, futhi ingamisa uchungechunge ngokusebenzisa isilawuli kude, ukuze ingabangeli ukwehluleka ukunciphisa futhi kuthinte ukukhishwa komsebenzi namandla awo wonke. isistimu ye-photovoltaic.
