Chii chinonzi MPPT uye MPPT hybrid solar inverter?

Mukushanda kwemagetsi emagetsi e photovoltaic, tagara tichitarisira kuwedzera kushandurwa kwesimba rechiedza kuva simba remagetsi kuitira kuchengetedza kushanda zvakanaka. Saka, tinogona sei kuwedzera simba rekugadzira simba remagetsi e photovoltaic?

Nhasi, ngatitaure nezve chinhu chakakosha chinokanganisa kushanda kwemagetsi emagetsi emagetsi ephotovoltaic - yakanyanya simba yekutevera tekinoroji, inova ndiyo yatinowanzo kudaidza.MPPT.

Iyo Maximum Power Point Tracking (MPPT) system igadziriro yemagetsi inoita kuti photovoltaic panel ibudise simba rakawanda remagetsi nekugadzirisa kushanda kwemodule yemagetsi. Inogona kunyatso kuchengetedza yakananga ikozvino inogadzirwa nepaneti yezuva mubhatiri, uye inogona kunyatsogadzirisa kushandiswa kwemagetsi epamba uye maindasitiri munzvimbo dziri kure uye nzvimbo dzevashanyi dzisingagoni kuvharwa nemagetsi emagetsi emagetsi, pasina kukonzera kusvibiswa kwezvakatipoteredza.

Iyo MPPT controller inogona kuona iyo inogadzirwa voltage ye solar panel munguva chaiyo uye inoteedzera yakakwira voltage uye ikozvino kukosha (VI) kuitira kuti sisitimu ikwanise kuchaja bhatiri neiyo yakanyanya simba kubuda. Inoshandiswa mune solar photovoltaic systems, kurongedza basa remagetsi ezuva, mabhatiri, uye mitoro ndiyo uropi hwe photovoltaic system.

Basa reMPPT

Basa reMPPT rinogona kuratidzwa mumutsara mumwe chete: simba rinobuda re photovoltaic cell rinobatana nekushanda kwekushanda kwemutungamiri weMPPT. Chete kana ichinge ichishanda pamhepo yakanyatsokodzera simba rayo rekubuda rinogona kuve neyakasiyana yakakosha kukosha.

Nekuti maseru ezuva anokanganiswa nekunze zvinhu zvakaita sechiedza chakasimba uye nharaunda, simba rawo rekubuda rinoshanduka, uye kusimba kwechiedza kunogadzira mamwe magetsi. Iyo inverter ine MPPT yakanyanya simba yekutevera ndeyekushandisa zvizere maseru ezuva uye inoita kuti imhanye pane yakanyanya simba poindi. Izvi zvinoreva kuti, pasi pemamiriro ekugara kwezuva, simba rinobuda mushure meMPPT richave rakakwirira kudarika iro pamberi peMPPT.

MPPT kutonga kunowanzo itwa kuburikidza neDC/DC shanduko yedunhu, iyo photovoltaic cell array yakabatana nemutoro kuburikidza neDC/DC dunhu, uye iyo yakanyanya simba yekutevera mudziyo inogara.

Tarisa ikozvino uye voltage shanduko ye photovoltaic array, uye gadzirisa basa kutenderera kwePWM yekutyaira chiratidzo cheDC / DC inoshandura zvichienderana nekuchinja.

Kune mitsara yemasekete, kana kupikisa kwemutoro kwakaenzana nekupikisa kwemukati kwemagetsi, magetsi ane simba guru rinobuda. Kunyangwe ese ese ari maviri photovoltaic maseru uye DC/DC kushandura maseketi akasimba asina mutsara, anogona kutariswa mutsara maseketi munguva pfupi pfupi. Nokudaro, chero bedzi kupikisa kwakaenzana kweDC-DC kutendeuka kwedunhu kunogadziriswa kuitira kuti nguva dzose ienzane nekudzivirira kwemukati kwe photovoltaic cell, iyo yakawanda inobuda ye photovoltaic cell inogona kuwanikwa, uye MPPT ye photovoltaic cell. zvinogonawo kuitwa.

Linear, zvisinei kwenguva pfupi, inogona kutorwa semutsara wedunhu. Nokudaro, chero bedzi kupikisa kwakaenzana kweDC-DC kutendeuka kwedunhu kunogadziriswa kuitira kuti igare yakaenzana ne photovoltaic.

Kupikiswa kwemukati kwebhatiri kunogona kuona kuburitsa kwakanyanya kweiyo photovoltaic cell uye zvakare kuona iyo MPPT yephotovoltaic cell.

Kushandiswa kweMPPT

Nezve chinzvimbo cheMPPT, vanhu vazhinji vanozove nemibvunzo: Sezvo MPPT yakakosha, nei isu tisingaione zvakananga?

Chaizvoizvo, MPPT inosanganiswa mune inverter. Kutora iyo microinverter semuenzaniso, iyo module-level MPPT controller inoteedzera yakanyanya simba poindi yePV module yega yega. Izvi zvinoreva kuti kunyange kana photovoltaic module isingashandisi, haizokanganisa simba rekugadzira simba remamwe ma modules. Semuenzaniso, mune yese photovoltaic system, kana imwe module yakavharwa ne50% yechiedza chezuva, iyo yakanyanya simba point tracking controllers yemamwe ma modules icharamba ichichengetedza iwo emhando yepamusoro yekugadzira.

Kana uchifariraMPPT yakasanganiswa solar inverter, kugamuchirwa kuti ubate photovoltaic mugadziri Radiance kuverenga zvimwe.
