Iwo ane chekuita nePV Inverter Anounzwa

1.Maximum power point tracking (MPPT) basa

Maximum power point tracking (MPPT) ndiyo yakakosha tekinoroji yephotovoltaic inverters. Sezvo simba rekubuda re photovoltaic module richichinja nekusimba kwemwaranzi yezuva uye tembiricha yemodule pachayo, pane yakakwana yekushandisa poindi, iyo yakanyanya simba poindi (MPP). Basa reMPPT nderekuita kuti photovoltaic module nguva dzose ishande pedyo nepamusoro pesimba remagetsi, nokudaro kuwedzera simba rekugadzira simba.

Kuti uwane MPPT, iyo photovoltaic inverter icharamba ichiona ikozvino uye kuchinja kwemhepo ye photovoltaic module, uye kugadzirisa kushanda kweiyo inverter maererano nekuchinja uku. Kazhinji, MPPT inowanikwa kuburikidza neDC / DC yekushandura dunhu, nekugadzirisa PWM drive signal duty ratio ye DC / DC converter, kuitira kuti kubudiswa kwe photovoltaic module nguva dzose kunochengetwa pedyo nepamusoro pesimba guru.

2.Power grid monitoring function

Iyo magetsi grid yekutarisa basa inogonesa iyophotovoltaic inverter kutarisa mamiriro emagetsi emagetsi munguva chaiyo, kusanganisira voltage, frequency, phase uye mamwe ma paramita, kuve nechokwadi chekuenderana uye kugadzikana kweiyo photovoltaic magetsi chiteshi uye gidhi remagetsi. Kuburikidza neiyo grid yekutarisa, iyo inverter inogona kugadzirisa yayo kuburitsa munguva chaiyo kuti ienderane kune shanduko mugedhi uye kuve nechokwadi chekuti simba remagetsi rinosangana nezvinodiwa zvegidhi. Uye zvakare, iyo gidhi remagetsi rekutarisa basa rinogonawo kubatsira mamaneja kunzwisisa mamiriro ekushanda kwegidhi remagetsi, kuwana uye kugadzirisa matambudziko angangoitika panguva yakakodzera, uye kuve nechokwadi chekushanda kwakagadzikana kwegedhi remagetsi.photovoltaic simba zvinomera.

3.Fault kuchengetedza basa

Photovoltaic inverter ine basa rakakwana rekudzivirira kukanganisa kutarisana nemamiriro akasiyana-siyana asina kunaka anogona kuitika mumashandisirwo chaiwo ekushandisa, kuchengetedza inverter pachayo uye zvimwe zvikamu zvegadziriro kubva mukukuvadza. Aya maficha akakundikana anosanganisira:

1. Input undervoltage uye overvoltage dziviriro:Kana iyo voltage yekupinda yadzikira kupfuura kana yakakwira pane imwe chiyero cheyakayerwa voltage, inverter inotanga nzira yekudzivirira kudzivirira kukuvara kwechishandiso.
2. Overcurrent protection:Kana iyo inoshanda ikozvino inodarika imwe chikamu cheiyo yakayerwa ikozvino, iyo inverter inocheka yega reketi kudzivirira yakawandisa ikozvino kubva mukukuvadza kune mudziyo.
3. Kubuda kwedziviriro yedunhu pfupi:Iyo inverter ine kukurumidza kupindura kupfupi wedunhu kudzivirira basa, iyo inogona kugura dunhu munguva pfupi pfupi mushure menguva pfupi yakaitika, uye kudzivirira midziyo kubva pakukanganisa kwepfupi wedunhu ikozvino.
4. Input reverse protection:Kana iyo yekuisa yakaringana uye iyo yakaipa electrode yakadzoserwa kumashure, iyo inverter ichatanga nzira yekudzivirira kudzivirira michina kubva pakukuvadzwa nereverse voltage.
5. Kudzivirira mheni:Iyo inverter ine yakavakirwa-mukati yekudzivirira mheni mudziyo, iyo inogona kuchengetedza midziyo kubva mukukuvadzwa kwemheni mumheni mamiriro ekunze.
6. Pamusoro pekudzivirira tembiricha:Iyo inverter zvakare ine pamusoro pekudzivirira tembiricha basa, kana tembiricha yemukati yemidziyo yakanyanya kukwira, inozodzikisa otomatiki simba kana kumira kudzivirira michina kuti isakuvadzwe nekuda kwekupisa.

Aya ekudzivirira kukanganisa anoshanda pamwechete anovimbisa kushanda kwakagadzikana uye kuchengetedzeka kweiyosolar inverter . Muchishandiso chinoshanda, basa rekudzivirira kukanganisa kwe photovoltaic inverter rine kukosha kukuru kuvandudza kuvimbika uye kugadzikana kwe photovoltaic power station.
