Pamene eni ake amtundu wa dzuwa akuwona kudalirika kwa magetsi awo a dzuwa, angaganize za ma modules amtundu woyamba omwe amagula kapena akhoza kuchita ma modules otsimikizika.Komabe, ma inverter a fakitale ndiye maziko a ntchito za solar ndipo ndizofunikira kuti zitsimikizire kuti nthawi yayitali.Dziwani kuti mtengo wa 5% wa zida mumagetsi opangira magetsi atha kupangitsa 90% ya nthawi yopumira.Mwachidziwitso, malinga ndi lipoti la 2018 la Sandia National Laboratory, ma inverters ndi omwe amachititsa kuti 91% yalephereke pama projekiti akuluakulu.
Pamene inverters imodzi kapena zingapo zikulephera, maulendo angapo a photovoltaic adzachotsedwa ku gridi, zomwe zidzachepetsa kwambiri phindu la polojekitiyi.Mwachitsanzo, taganizirani ntchito yoyendera dzuwa ya 250 megawati (MW).Kulephera kwa inverter imodzi yapakati ya 4 MW kungayambitse kutaya kwa 25 MWh / tsiku, kapena pa mgwirizano wogula mphamvu (PPA) mlingo wa $ 50 / tsiku, Kutayika kwa 1,250 MWh patsiku.Ngati gulu lonse la 5MW photovoltaic latsekedwa kwa mwezi umodzi panthawi yokonzanso inverter kapena kusinthidwa, kutayika kwa ndalama za mwezi umenewo kudzakhala US $ 37,500, kapena 30% ya mtengo wogula woyambirira wa inverter.Chofunika kwambiri, kutayika kwa ndalama ndi chizindikiro chowononga pamapepala a eni ake a katundu ndi mbendera yofiira kwa osunga ndalama amtsogolo.
Kuchepetsa chiwopsezo cha kulephera kwa ma inverter ndikoposa kungogula kuchokera pamndandanda wa omwe amapereka ndalama zopangira ma inverter imodzi ndikusankha mtengo wotsika kwambiri.
Ndili ndi zaka zoposa khumi pakupanga ndi kuyang'anira ma inverters amitundu yosiyanasiyana kwa opanga akuluakulu, ndikukutsimikizirani kuti ma inverters sizinthu.Wopereka aliyense ali ndi makonzedwe osiyana a eni ake, miyeso ya mapangidwe, magawo ndi mapulogalamu, komanso zigawo zomwe zili pashelefu zomwe zingakhale ndi khalidwe lawo komanso nkhani zogulitsira.
Ngakhale mutadalira chitsanzo chotsimikiziridwa chomwe sichinayambe chalephera kugwira ntchito ndi kukonza bwino, mungakhalebe pangozi.Popeza makampani opanga ma inverter akhala akukakamizidwa kuti achepetse ndalama zopangira, ngakhale ma inverters amtundu womwewo afananizidwa, mapangidwewo apitiliza kusinthidwa.Chifukwa chake, mtundu wa inverter womwe umakonda womwe unali wodalirika miyezi isanu ndi umodzi yapitayo ukhoza kukhala ndi zigawo zingapo zazikulu ndi fimuweya ikayikidwa mu polojekiti yanu yaposachedwa.
Kuti muchepetse chiopsezo cha kulephera kwa inverter, ndikofunikira kumvetsetsa momwe inverter imalephera komanso zomwe mungachite kuti muchepetse zoopsazi.
#1 Kupanga: Kulephera kwa mapangidwe kumakhudzana ndi kukalamba msanga kwa zida zazikulu zamagetsi, monga insulated gate bipolar transistors (IGBT), ma capacitor, board board ndi ma board olumikizirana.Izi zidapangidwa kuti zizigwiritsidwa ntchito ndi zinthu zina, monga kutentha ndi kupsinjika kwamagetsi / makina.
Chitsanzo: Ngati wopanga inverter apanga IGBT ya stack yake yamagetsi kuti iwonetsedwe pa kutentha kwakukulu kwa 35 ° C, koma inverter imayenda ndi mphamvu zonse pa 45 ° C, inverter rating yopangidwa ndi wopangayo ndi IGBT yolakwika.Chifukwa chake, IGBT iyi imatha kukalamba ndikulephera msanga.
Nthawi zina, opanga ma inverter amapanga ma inverter okhala ndi ma IGBT ochepa kuti achepetse ndalama, zomwe zingayambitsenso kutentha kwapakati / kupanikizika komanso kukalamba msanga.Ziribe kanthu kuti ndizosamveka bwanji, izi ndizochitika zomwe ndakhala ndikuziwona m'makampani a dzuwa kwa zaka 10-15.
Kutentha kwamkati kwa ntchito ndi kutentha kwa gawo la inverter ndizofunikira kwambiri pakupanga ma inverter ndi kudalirika.Kulephera koyambirira kumeneku kumatha kuchepetsedwa ndi kapangidwe kabwino ka kutentha, kutulutsa kutentha komweko, kuyika ma inverters m'malo otentha otsika, komanso kuyika njira zodzitetezera.
#2 Mayeso odalirika.Wopanga aliyense ali ndi ma protocol oyesa makonda ndi eni ake kuti ayese ndikuyesa ma inverters amitundu yosiyanasiyana yamagetsi.Kuphatikiza apo, kufupikitsidwa kwa moyo wamapangidwe kungafune kudumpha gawo loyesa lamitundu ina yokwezeka ya inverter.
#3 mndandanda wa zolakwika.Ngakhale wopanga asankha gawo loyenera kuti agwiritse ntchito moyenera, gawolo likhoza kukhala ndi zolakwika mu inverter kapena kugwiritsa ntchito kulikonse.Kaya ndi ma IGBT, ma capacitors kapena zida zina zazikulu zamagetsi, kudalirika kwa inverter yonse kumadalira ulalo wofooka kwambiri pamtundu wake woperekera.Ukadaulo wokhazikika komanso chitsimikizo chaubwino ziyenera kuchitidwa kuti muchepetse chiwopsezo cha zinthu zolakwika zomwe pamapeto pake zimalowa mumtundu wanu wa solar.
#4 Consumables.Opanga ma inverter amakhala achindunji kwambiri pamakonzedwe awo okonza, kuphatikiza kusinthira zinthu monga mafani, ma fuse, ophwanya ma circuit ndi switchgear.Chifukwa chake, inverter imatha kulephera chifukwa chosayenera kapena kusamalidwa.Komabe, mofananamo, atha kulepheranso chifukwa cha mapangidwe kapena zolakwika za ma inverters a chipani chachitatu kapena zogwiritsira ntchito OEM.
#5 Kupanga: Pomaliza, ngakhale chosinthira chopangidwa bwino kwambiri chokhala ndi unyolo wabwino kwambiri chikhoza kukhala ndi mzere wosokonekera.Mavuto amzere awa amatha kuchitika m'mbali zonse zakupanga.Zitsanzo zina:
Apanso, kuti musunge nthawi komanso phindu lalifupi komanso lalitali, ndikofunikira kukhazikitsa inverter yotsimikiziridwa ndi yodalirika.Monga kampani yotsimikizira zamtundu wachitatu, China Eastern Airlines sakonda opanga, zitsanzo kapena tsankho lamtundu uliwonse.Chowonadi ndi chakuti onse opanga ma inverter ndi maunyolo awo operekera amakhala ndi zovuta nthawi ndi nthawi, ndipo mavuto ena amakhala pafupipafupi kuposa ena.Choncho, pofuna kuchepetsa chiopsezo cha kulephera kwa inverter, njira yokhayo yodalirika ndiyo ndondomeko yodalirika yodalirika komanso yodalirika (QA).
Kwa makasitomala ambiri omwe ali ndi chiwopsezo chachikulu chazachuma, dongosolo lotsimikizira mtundu liyenera kusankha chosinthira chabwino kwambiri chomwe chilipo potengera kapangidwe kake, kapangidwe kake, magwiridwe antchito, komanso zosankha zamtundu wa projekiti, zomwe zingaganizire zanyengo pamalowa. , zofunikira za gridi, zofunikira za nthawi yowonjezera ndi zina zachuma.
Kuwunikiridwa kwa makontrakitala ndi kuwunikiranso kwa chitsimikizo kudzawonetsa chilankhulo chilichonse chomwe chingaike eni ake katundu pachiwopsezo pazamalamulo pazolinga zilizonse zamtsogolo.
Chofunika koposa, dongosolo lanzeru la QA liyenera kuphatikizapo kuwunika kwa fakitale, kuyang'anira kupanga ndi kuyesa kuvomereza ku fakitale (FAT), kuphatikizira kuyang'ana malo ndi kuyezetsa mtundu wa ma inverter apadera opangira magetsi adzuwa.
Zinthu zing'onozing'ono zimapanga chithunzi chonse cha polojekiti yopambana ya dzuwa.Ndikofunika kuti musanyalanyaze khalidweli posankha ndikuyika ma inverters mu polojekiti yanu ya dzuwa.
