Kana varidzi vesolar asset vakafunga kuvimbika kwezvidyarwa zvavo zvesimba rezuva, vanogona kufunga nezveyekutanga-kirasi solar modules dzavanotenga kana kuita module quality assurance.Nekudaro, ma inverters efekitori ndiwo musimboti wekushanda kwesolar projekiti uye yakakosha pakuona nguva.Izvo zvinofanirwa kucherechedzwa kuti 5% mutengo wemidziyo mune photovoltaic simba chirimwa inogona kukonzera 90% yesimba rekudyara nguva.Zvekureva, zvinoenderana ne2018 Sandia National Laboratory report, inverters ndiyo inokonzeresa inosvika 91% yekutadza mumapurojekiti makuru ekushandisa.
Kana imwe kana kupfuura inverters ikakundikana, akawanda photovoltaic arrays achabviswa kubva kune grid, izvo zvichanyanya kuderedza purofiti yeprojekti.Semuenzaniso, funga nezve 250 megawatt (MW) chirongwa chezuva.Kutadza kweimwe 4 MW yepakati inverter kunogona kukonzera kurasikirwa kunosvika makumi maviri neshanu MWh / zuva, kana chibvumirano chekutenga magetsi (PPA) chiyero chemadhora makumi mashanu / zuva, Kurasikirwa kwe1,250 MWh pazuva.Kana iyo yose 5MW photovoltaic array yakavharwa kwemwedzi mumwe panguva yekugadzirisa inverter kana kuchinjwa, kurasikirwa kwemari yemwedzi iwoyo kuchava US $ 37,500, kana 30% yepakutanga kutenga mutengo we inverter.Zvinotonyanya kukosha, kurasikirwa kwemari chiratidzo chinoparadza pachiyero chevaridzi veasset uye mureza mutsvuku wevachaisa mari.
Kudzikisa njodzi yekutadza inverter kunopfuura kungotenga kubva kune yevamiriri runyorwa rwekubhadhara tier imwe inverter vagadziri uye kusarudza mutengo wakaderera.
Neanopfuura makore gumi eruzivo mukugadzira uye kutonga inverters emhando dzakasiyana siyana dzevagadziri vakuru, ndinogona kukuvimbisa kuti inverters hazvisi zvinhu.Mutengesi wega wega ane seti yakasiyana yemagadzirirwo evaridzi, dhizaini zviyero, zvikamu uye software, pamwe neakajairwa kunze-pasherufu zvikamu izvo zvingave neazvo emhando uye nyaya dzekutengesa.
Kunyange kana iwe uchivimba nemuenzaniso wakaratidzwa usina kumbokundikana mukushanda kwakakodzera nekugadzirisa, iwe unogona kunge uchiri pangozi.Sezvo inverter makambani anga ari pasi pekumanikidzwa kudzikisa mutengo wekugadzira, kunyangwe iwo ma inverters emhando imwechete akafananidzwa, dhizaini icharamba ichivandudzwa.Naizvozvo, iyo yakasarudzika inverter modhi yaive yakavimbika mwedzi mitanhatu yapfuura inogona kunge iine akasiyana makiyi zvikamu uye firmware kana yaiswa mupurojekiti yako yazvino.
Kuti uderedze njodzi yekutadza inverter, zvakakosha kuti unzwisise kuti inverter inotadza sei uye ndeapi matanho anogona kutorwa kuderedza njodzi idzi.
#1 Dhizaini: Kutadza kwedhizaini kune chekuita nekuchembera kusati kwasvika kwezvinhu zvakakosha zvemagetsi, senge insulated gedhi bipolar transistors (IGBT), capacitor, mabhodhi ekudzora uye mabhodhi ekutaurirana.Izvi zvikamu zvakagadzirirwa mamwe maapplication uye mamiriro, senge tembiricha uye magetsi / mechaniki kushushikana.
Muenzaniso: Kana iyo inverter inogadzira iyo IGBT yesimba rayo stack kuti ionekwe pane yakanyanya ambient tembiricha ye35 ° C, asi inverter inomhanya nesimba rakazara pa45 ° C, inverter rating yakagadzirwa nemugadziri haina kururama IGBT.Naizvozvo, iyi IGBT inogona kuchembera nekutadza nguva isati yakwana.
Dzimwe nguva, vanogadzira inverter vanogadzira inverters ine mashoma IGBTs kuitira kuderedza mutengo, izvo zvinogona zvakare kutungamira kune yakakwira avhareji tembiricha yekushanda / kushushikana uye kuchembera nguva isati yakwana.Hazvina mhosva kuti hazvina musoro sei, iyi ichiri tsika inoenderera yandakaona muindasitiri yezuva kwe10-15 makore.
Iyo yemukati yekushanda tembiricha uye tembiricha yechikamu cheiyo inverter ndiyo yakakosha yekufunga nezve inverter dhizaini uye kuvimbika.Uku kutadza kusati kwasvika kunogona kuderedzwa nekugadzirwa kuri nani kwemafuta, kupisa kwenzvimbo, kutumirwa kwemainverters munzvimbo dzakaderera dzetembiricha, uye kusarudzwa kwekuchengetedza kwakawanda kwekudzivirira.
#2 Kuvimbika bvunzo.Wese mugadziri ane akagadziridza uye evaridzi bvunzo mapuroteni kuti aongorore uye kuyedza inverters yeakasiyana masimba masimba.Uye zvakare, iyo yakapfupikiswa dhizaini yehupenyu kutenderera ingangoda kusvetuka yakakosha yekuyedza chikamu cheakakwidziridzwa inverter modhi.
#3 dzakatevedzana dzehurema.Kunyangwe kana mugadziri akasarudza iyo chaiyo chikamu cheiyo chaiyo application, iyo chikamu pachayo inogona kunge iine hurema mune inverter kana chero application.Kunyangwe iri IGBTs, capacitors kana zvimwe zvakakosha zvemagetsi zvikamu, kuvimbika kweiyo inverter yese kunoenderana neiyo isina kusimba chinongedzo muhutano hwekugovera kwayo keteni.Tekinoroji tekinoroji uye vimbiso yemhando inofanirwa kuitiswa kudzikisa njodzi yezvinhu zvakakanganisika pakupedzisira kupinda mune yako solar array.
#4 Consumables.Vagadziri veInverter vanonyatso tsanangura nezvezvirongwa zvavo zvekugadzirisa, kusanganisira kutsiva kwezvinhu zvinoshandiswa senge mafeni, fuse, mabreak breaker uye switchgear.Nokudaro, inverter inogona kukundikana nekuda kwekusafanira kana kusagadzirisa.Nekudaro, zvakafanana, ivo vanogona zvakare kutadza nekuda kwekugadzira kana kugadzira kukanganisa kwechitatu-bato inverters kana OEM zvinodyiwa.
#5 Kugadzira: Chekupedzisira, kunyangwe iyo yakanyatso dhizaini inverter ine yakanakisa yekugovera cheni inogona kunge iine isina kunaka mutsara wegungano.Aya matambudziko emutsetse wekusangana anogona kuitika mune ese maficha ekugadzira maitiro.Mimwe mienzaniso:
Zvekare, kuitira kuchengetedza uptime uye kwenguva pfupi uye kwenguva refu purofiti, zvakakosha kuisa yakaratidza uye yakavimbika inverter.Sekambani yechitatu-bato rekusimbisa mhando, China Eastern Airlines haina hanya nevagadziri, modhi kana kusarura chero mhando.Ichokwadi ndechekuti vese vanogadzira inverter uye macheni avo ekupa vanozove nematambudziko emhando nguva nenguva, uye mamwe matambudziko anowedzera kupfuura mamwe.Nokudaro, kuitira kuti uderedze njodzi yekukundikana kwe inverter, mhinduro chete yakavimbika ndeyekutendeseka kunoenderana uye kuvimbiswa kwehutano (QA) chirongwa.
Kune vazhinji vatengi vemapurojekiti makuru ekushandisa ane njodzi huru yemari, chirongwa chekuvimbisa chemhando chinofanira kutanga chasarudza yakanakisa inverter inowanikwa zvichienderana nedhizaini yayo, dhizaini, kuita kwesaiti, uye sarudzo-yakanangana neprojekiti, iyo inozofunga nezvemamiriro ekunze pane Saiti Mamiriro. , grid zvinodiwa, uptime zvinodiwa uye zvimwe zvinhu zvemari.
Ongororo yekondirakiti uye ongororo yewaranti icharatidza chero mutauro unogona kuisa muridzi weasset panjodzi yepamutemo mune chero ramangwana rewaranti zvichemo.
Kunyanya kukosha, chirongwa cheQA chehungwaru chinofanirwa kusanganisira kuongororwa kwefekitori, kutarisisa kugadzirwa uye kugamuchirwa kwefekitori kuyedzwa (FAT), kusanganisira kutariswa kwenzvimbo uye kuyedzwa kwemhando yemainverters anogadzirwa emagetsi ezuva.
Zvinhu zvidiki zvinoumba mufananidzo wakazara weyakabudirira solar project.Izvo zvakakosha kuti urege kuregeredza mhando kana uchisarudza uye nekuisa ma inverters mune yako solar purojekiti.
