Iyo inverter isimba rekugadzirisa simba rinoumbwa semiconductor zvishandiso, izvo zvinonyanya kushandiswa kushandura DC simba kuita AC simba.Iyo inowanzo umbwa neyekusimudzira wedunhu uye inverter bhiriji wedunhu.Iyo inosimudzira dunhu inowedzera iyo DC voltage yesolar cell kune iyo DC voltage inodiwa kune inverter yekubuda kutonga;iyo inverter bhiriji reketi inoshandura yakawedzera DC voltage kuita AC voltage ine yakajairika frequency zvakaenzana.
Inverter, inozivikanwawo semagetsi regulator, inogona kukamurwa kuita yakazvimirira magetsi uye grid-yakabatana kushandiswa maererano nekushandiswa kwe inverter mune photovoltaic simba rekugadzira system.Zvinoenderana neiyo waveform modulation nzira, inogona kukamurwa kuita square wave inverter, nhanho wave inverter, sine wave inverter, uye yakasanganiswa matatu-chikamu inverter.Kune ma inverters anoshandiswa mugridi-akabatana masisitimu, anogona kukamurwa kuita transformer-mhando inverters uye transformer-shoma inverters zvichienderana nekuti pane transformer.Iwo makuru tekinoroji ma parameter e solar photovoltaic inverter ndeaya:
1. Rated output voltage
Iyo photovoltaic inverter inofanirwa kukwanisa kuburitsa iyo yakatemerwa voltage kukosha mukati meinotenderwa kushanduka kweiyo yakataurwa inopinza DC voltage.Kazhinji, kana iyo yakatemerwa kubuda voltage iri imwe-chikamu 220v uye matatu-chikamu 380v, iyo voltage fluctuation kutsauka kunotsanangurwa sezvizvi.
(1) Kana uchimhanya wakadzikama, zvinowanzodiwa kuti voltage fluctuation deviation isapfuure ± 5% yemutengo wakayerwa.
(2) Kana mutoro ukangoerekana wachinjwa, kutsauka kwemagetsi hakupfuuri ± 10% yehuwandu hwehuwandu.
(3) Pasi pemamiriro ekushanda, kusaenzana kwematatu-phase voltage inobuda ne inverter haifaniri kudarika 8%.
(4) Kukanganiswa kweiyo voltage waveform (sine wave) yekubuda kwechikamu-nhatu inowanzodikanwa kuti isapfuure 5%, uye chikamu chimwe chete chinobuda hachifanire kudarika 10%.
(5) Kutsauka kweiyo frequency ye inverter inobuda AC voltage inofanira kunge iri mukati me1% pasi pemamiriro ekushanda.Iyo inobuda voltage frequency inotsanangurwa muyero yenyika Gb/t 19064-2003 inofanira kuva pakati pe49 ne51hz.
2. Mutoro simba chinhu
Saizi yemutoro simba chinhu inoratidza kugona kweiyo inverter kutakura inductive mutoro kana capacitive mutoro.Pasi pemamiriro eiyo sine wave, iyo mutoro simba chinhu 0.7 kusvika 0.9, uye yakayerwa kukosha ndeye 0.9.Muchiitiko cheimwe simba rekutakura, kana simba re inverter rakaderera, iyo inodiwa simba ye inverter ichawedzera, zvichiita kuti kuwedzerwa kwemari.Panguva imwecheteyo, simba rinoratidzika re AC redunhu re photovoltaic system rinowedzera, uye dunhu rinowedzera.Kana yakakura, kurasikirwa kuchawedzera, uye kushanda kwehurongwa kuchadererawo.
3. Yakatemerwa kubuda ikozvino uye yakatemerwa kubuda kwehuwandu
Yakatemerwa yakabuda ikozvino inoreva iyo yakatemerwa kubuda ikozvino kweiyo inverter mukati meyakatarwa mutoro simba factor renji, iyo unit ndeye;rated inobuda simba inoreva chigadzirwa cheyakayerwa yakabuda voltage uye yakayerwa yakabuda ikozvino ye inverter kana yakabuda simba chinhu chiri 1 (kureva pure resistive load), unit is kva kana kw.
