Withkukurumidza kukura kwekugovera photovoltaic, matenga akawanda uye akawanda "akapfekedzwa photovoltaic" uye anova chigadziro chakasvibirira chekugadzira magetsi.Kugadzirwa kwemagetsi kwePV system kwakabatana zvakananga nemari yekudyara yehurongwa, maitiro ekuvandudza sisitimu yekugadzira magetsi ndiyo inotarisa indasitiri yese.
1. Musiyano mukugadzira simba rematenga ane maitiro akasiyana
Sezvatinoziva tose, kutarisa kwakasiyana kwe photovoltaic modules kunogamuchira kupenya kwezuva kuchave kwakasiyana, saka simba rekugadzira photovoltaic systems uye photovoltaic module orientation ine hukama hwepedyo.Maererano nedheta, munzvimbo iri pakati pe35 ~ 40 ° N latitude, somuenzaniso, irradiance inogamuchirwa nematenga ane maitiro akasiyana-siyana uye azimuths yakasiyana: tichifunga kuti simba rekugadzira denga rakatarisana nekumaodzanyemba ndiro 100, simba rekugadzira magetsi. matenga akatarisana nekumabvazuva nekumavirira anenge makumi masere, uye mutsauko wekugadzira simba unogona kunge uri makumi maviri muzana.Sezvo kona inochinja kubva kumaodzanyemba kuenda kumabvazuva nekumadokero, kugadzirwa kwemagetsi kunenge kuri kudzikira.
Kazhinji kutaura, simba repamusoro rekugadzira simba regadziriro rinowanikwa kuchamhembe kwehemisphere ine yakafanira maodzanyemba yakatarisa uye yakanakisa kona yekurerekera.Zvisinei, mukuita, kunyanya mukuparadzirwa kwe photovoltaic, nemamiriro ekugadzirisa chivako uye zvipingamupinyi zvepanzvimbo, photovoltaic modules kazhinji haigoni kuiswa mune yakanakisa kutaridzika uye yakanakisa tilt angle, chikamu multi-orientation chave chimwe chekugovera denga photovoltaic system. simba rekugadzira marwadzo mapoinzi, saka nzira yekudzivirira kurasikirwa kwesimba remagetsi rinounzwa ne-multi-orientation, rave rimwe dambudziko mukusimudzira indasitiri.
2. Iyo "short board effect" mumatenga akawanda-directional
Mune yechinyakare tambo inverter system, mamodule akabatanidzwa munhevedzano, uye kugona kwavo kwekugadzira simba kunodzikiswa ne "short board effect."Kana tambo yemamodule ichigoverwa mumativi akawanda edenga, iyo yakaderedzwa kugadzirwa kwesimba kweimwe yemamodule ichakanganisa kugadzirwa kwesimba kwese tambo yemamodules, nokudaro kukanganisa simba rekugadzira simba remaitiro akawanda edenga.
Micro inverter inotora yakazara parallel yedunhu dhizaini, ine yakazvimiririra yakanyanya simba point tracking (MPPT) basa, rinogona kubvisa zvachose "short board athari" uye ive nechokwadi chekuti module yega yega inoshanda yakazvimirira uye kugadzirwa kwemagetsi hakukanganise mumwe nemumwe, zvichienzaniswa netambo yechinyakare. inverter system, pasi pemamiriro akafanana, inogona kuburitsa 5% ~ 25% yakawanda simba uye kugadzirisa mari yekudyara.
Kunyange kana ma modules akaiswa pamatenga ane maitiro akasiyana-siyana, kubudiswa kwemodule imwe neimwe kunogona kugadziriswa pedyo nepamusoro pesimba, kuitira kuti mamwe matenga anogona "kupfekedzwa muPV" uye awedzere kukosha.
3. Micro-inverter mune yakawanda-directional padenga application
Micro inverters, neayo akasarudzika ehunyanzvi mabhenefiti, akanyanya kukodzera kune akawanda-directional padenga PV application, uye akashandira anopfuura zana nyika nematunhu, achipa MLPE module-level tekinoroji mhinduro kune akawanda-directional padenga remba PV.
4. PV Project yemhuri
Munguva pfupi yapfuura, chirongwa che 22.62kW system yePV chakavakwa muBrazil.Pakutanga kwekugadzirwa kweprojekti, muridzi aitarisira Mushure mekugadzirwa kweprojekti, maPV modules akazoiswa pamatenga manomwe emhando dzakasiyana-siyana, uye nekushandiswa kwezvigadzirwa zve micro-inverter, matenga akashandiswa zvizere.Mukushanda chaiko kwesimba remagetsi, rinobatwa nemaitiro akawanda, kuwanda kwezuva rinogamuchirwa nemamodules padenga rakasiyana rinosiyana, uye simba ravo rekugadzira simba rinosiyana zvakanyanya.Tora ma modules akakomberedzwa mumufananidzo uri pasi apa semuenzaniso, matenga maviri akatarisana akatenderedzwa mutsvuku uye bhuruu anoenderana nechekumadokero uye kumabvazuva kumativi.
5. Zvirongwa zveCommerce PV
Pamusoro pemapurojekiti ekugara, ma micro inverters ari kushandiswawo mune zvekutengesa uye maindasitiri maapplication akatarisana nedenga.Gore rapera, chirongwa chePV chekutengeserana uye cheindasitiri chakaiswa padenga rechitoro chikuru muGoits, Brazil, chine simba re48,6 kW.Pakutanga kwekugadzirwa kweprojekti uye kusarudzwa, nzvimbo yacho yakatenderedzwa mumufananidzo uri pasi apa.Zvichienderana nemamiriro ezvinhu aya, purojekiti yakasarudza zvese zvigadzirwa zve-micro-inverter, kuitira kuti kugadzirwa kwemagetsi ega ega moduru yedenga kusingabatanidze mumwe nemumwe, kuve nechokwadi chekuti simba rekugadzira simba rehurongwa.
Maonero akawanda akave chimwe chinhu chakakosha chekuparadzirwa kwedenga reimba PV nhasi, uye ma micro inverters ane chikamu-chikamu MPPT basa pasina mubvunzo isarudzo yakakodzera kutarisana nekurasikirwa kwemagetsi kunokonzerwa neakasiyana maitiro.Unganidza chiedza chezuva kuti chivhenekere mativi ose enyika.
