Vamwe vanhu vanoti iyo photovoltaic inverter mutengo wakakwirira zvikuru kupfuura module, kana isingashandisi zvakakwana simba guru, inokonzera kuparara kwezvinhu.Nokudaro, anofunga kuti simba rose rekugadzirwa kwemuti rinogona kuwedzerwa nekuwedzera photovoltaic modules zvichienderana nepamusoro pesimba rekuisa simba re inverter.Asi ndizvo chaizvo here?

Kutaura zvazviri, izvi handizvo zvakataurwa neshamwari yacho.Photovoltaic inverter uye photovoltaic module ratio ndeyechokwadi chikamu chesainzi.Kungogadziriswa kunonzwisisika chete, kuiswa kwesayenzi kunogona kupa zvakakwana kutamba kwekuita kwechikamu chimwe nechimwe, kuti uwane hutano hwakakwana hwekugadzira simba.Mazhinji mamiriro ezvinhu anofanirwa kufungwa pakati pe photovoltaic inverter uye photovoltaic module, yakadai sechiedza chekukwirira kwechiedza, nzira yekuisa, site factor, module uye inverter pachayo uye zvichingodaro.

Chekutanga, light elevation factor

Solar simba resource nzvimbo dzinogona kukamurwa kuita makirasi mashanu, yekutanga, yechipiri uye yechitatu marudzi enzvimbo iyo chiedza chitubu chakapfuma, yakawanda yenyika yedu ndeyemakirasi aya, saka yakakodzera kwazvo kuisirwa photovoltaic simba rekugadzira hurongwa.Nekudaro, iyo radiation intensity inosiyana zvakanyanya munzvimbo dzakasiyana.Kazhinji kutaura, kukura kwakaita solar altitude Angle, kusimba kwemwaranzi yezuva, uye nekukwirira kwepamusoro, kusimba kwemwaranzi yezuva.Munzvimbo dzine simba rezuva rakakwirira, kupisa kwekushisa kwe photovoltaic inverter zvakare kwakashata, saka inverter inofanira kuderedzwa kuti iite, uye chikamu chezvikamu chichave chakaderera.

Zviviri, kuisa zvinhu

Iyo inverter uye chikamu chiyero che photovoltaic magetsi chiteshi chinosiyana nenzvimbo yekuisa uye nzira.

1.Dc side system kunyatsoshanda

Nemhaka yokuti kureba pakati pe inverter uye module ipfupi kwazvo, tambo yeDC ipfupi kwazvo, uye kurasikirwa kuduku, kushanda kweDDC side system kunogona kusvika 98%.Centralised pasi-based power stations hazvinyanyi kufadza nekuenzanisa.Nekuda kwekuti tambo yeDC yakareba, simba rinobva pamwaranzi yezuva kuenda kune photovoltaic module rinoda kupfuura nepakati peDC tambo, bhokisi rekubatanidza, DC yekugovera kabhineti nemimwe michina, uye kushanda zvakanaka kweDC side system kunowanzo kuve pasi pe90% .

2. Simba grid voltage kuchinja

Iyo yakatemerwa yakanyanya kuburitsa simba reiyo inverter haisi nguva dzose.Kana iyo grid-yakabatana grid inodonha, ipapo inverter haigone kusvika kune yayo yakatarwa.Ngatitii tinotora 33kW inverter, iyo yakanyanya kubuda ikozvino 48A uye yakatemerwa inobuda voltage i400V.Zvinoenderana nematatu-chikamu simba kuverenga formula, iyo inobuda simba ndeye 1.732 * 48 * 400 = 33kW.Kana iyo grid voltage inodonha kusvika ku360, simba rekubuda richava 1.732 * 48 * 360 = 30kW, risingakwanisi kusvika kune simba rakarongwa.Kuita kuti kugadzirwa kwemagetsi kusashande.

3.inverter kupisa kupisa

Kupisa kweiyo inverter kunokanganisawo simba rekubuda reiyo inverter.Kana iyo inverter heat dissipation effect isina kunaka, ipapo simba rekubuda richaderera.Nokudaro, inverter inofanira kuiswa pasina chiedza chezuva, mamiriro akanaka emhepo.Kana iyo yekuisa nharaunda isina kunaka zvakakwana, saka kwakakodzera derating kunofanirwa kutariswa kudzivirira iyo inverter kubva pakupisa.

Tatu.Zvikamu pachazvo

Photovoltaic modules kazhinji ane hupenyu hwesevhisi ye25-30 makore.Kuti ive nechokwadi chekuti module inogona kuramba ichigona kupfuura 80% kushanda zvakanaka mushure mehupenyu hwesevhisi, general module fekitori ine muganho wakakwana we0-5% mukugadzira.Mukuwedzera, isu tinowanzo tenda kuti iyo yakajairwa mamiriro ekushandisa eiyo module ndeye 25 °, uye iyo photovoltaic module tembiricha inoderera, iyo module simba ichawedzera.

Ina, inverter pachayo zvinhu

1.inverter kushanda zvakanaka uye hupenyu

Kana tikaita kuti inverter ishande nesimba guru kwenguva yakareba, hupenyu hwe inverter huchaderedzwa.Tsvakurudzo inoratidza kuti hupenyu hwe inverter inoshanda pa80% ~ 100% simba inoderedzwa ne20% pane iyo pa40% ~ 60% kwenguva yakareba.Nekuti iyo system ichapisa zvakanyanya kana ichishanda nesimba rakakura kwenguva yakareba, tembiricha yekushandisa system yakanyanya, iyo inokanganisa hupenyu hwebasa.

2,yakanakisa kushanda voltage renji ye inverter

Inverter inoshanda voltage payakayerwa voltage, yakanyanya kushanda zvakanaka, single-phase 220V inverter, inverter input yakayerwa voltage 360V, matatu-phase 380V inverter, input rated voltage 650V.Zvakadai se3 kw photovoltaic inverter, ine simba re260W, kushanda kwemagetsi e30.5V 12 blocks ndiyo inonyanya kukodzera;Uye 30 kW inverter, kugovera simba kwe260W zvikamu 126 zvidimbu, uye ipapo nzira imwe neimwe 21 tambo ndiyo inonyanya kukodzera.

3. Kuwanda kwehuwandu hwe inverter

Ma inverters akanaka anowanzo kuve nekuremedza, uye mamwe mabhizinesi haana kuwandisa.Iyo inverter ine simba rakawanda rekuremedza inogona kuremedza iyo yakanyanya kuburitsa simba 1.1 ~ 1.2 nguva, inogona kuve ne 20% zvimwe zvikamu kupfuura iyo inverter isina kuwandisa simba.

Photovoltaic inverter uye module haina kurongeka uye, kuti ive inonzwisisika collocation, kuitira kudzivirira kurasikirwa.Pakuisa photovoltaic magetsi zviteshi, isu tinofanirwa kufunga zvakasiyana zvinhu zvizere, uye sarudza photovoltaic mabhizinesi ane yakanakisa dhizaini yekuisa.
