Background:
Zvinoenderana nemitemo yazvino ine chekuita negedhi renyika, nzvimbo imwe chete-yakabatana magetsi emagetsi kazhinji haipfuure 8 kilowatts, kana matatu-chikamu-akabatana network anodiwa. Pamusoro pezvo, dzimwe nzvimbo dzekumaruwa muChina hadzina magetsi echikamu chetatu, uye dzinongokwanisa kuisa chikamu chimwe chete kana vabvumidza chirongwa ichi (kana vachida kushandisa simba rezvikamu zvitatu, vanofanira kubhadhara makumi ezviuru zveyuan mukuvaka. mari). Vanoisa uye vashandisi vekupedzisira vanofanirwa kufunga nezve mutengo wekudyara. Kukosheswa kuchapihwa zvakare kuisa single-phase masisitimu.
Muna 2018 uye zvichienda mberi, Hurumende ichajekesa kushandiswa kwekubatsira kwe photovoltaic power generation subsidies. Ndichiri kuona huwandu hwekudyara kwezvidyarwa zvemagetsi uye pundutso yevatengi, kuti uwedzere huwandu hwakaiswa, 8KW single-phase masisitimu ichava sarudzo yakanakisa kumakambani makuru ekuisa.
Parizvino, iyo yakanyanya simba ye-single-phase inverters yakaunzwa nevakuru vanogadzira inverter muChina i6-7KW. Pakuisa 8KW magetsi emagetsi, mugadziri wega wega anokurudzira kushandiswa kwemainverters maviri e5KW + 3KW kana 4KW + 4KW. Chirongwa. Urongwa hwakadaro huchaunza dambudziko rakawanda kumugadziri maererano nemari yekuvaka, kutarisa, uye gare gare kushanda nekugadzirisa. Iyo itsva 8KW single-phase inverter NCA8K-DS yeNaton Energy, simba rekubuda rinogona kusvika 8KW, rinogona kugadzirisa zvakanangana nemushandisi akati wandei marwadzo.
Iyo inotevera Xiaobian kune yakajairwa 8KW magetsi chirimwa semuenzaniso, tora munhu wese kuti anzwisise iyi 8KW single-phase inverter mukana. Makumi matatu nematanhatu polycrystalline 265Wp yakakwirira-inoshanda zvikamu zvinosarudzirwa vatengi. Iyo tekinoroji parameter yezvikamu ndeiyi inotevera:
Zvinoenderana neyakajairwa 5KW + 3KW modhi, ma inverters maviri anodiwa, ayo machina 3KW akabatanidzwa kune yakazara gumi module, 5KW michina yakabatana netambo mbiri, uye imwe neimwe module yakabatana negumi modules.
Tarisa uone magetsi paramita eNathon Energy's 8KW imwe-kamera NAC8K-DS (sezvinoratidzwa patafura inotevera). 30 zvikamu zvakakamurwa kuita tambo nhatu kuti uwane iyo inverter:
MPPT1: 10 tambo, 2 tambo yekuwana
MPPT2: tambo gumi, 1 tambo yekuwana
Natong 8KW single-phase inverter NAC8K-DS yekutanga magetsi dhayagiramu:
Nekuenzanisa, zvakaonekwa kuti kushandisa Nato Energy NAC8K-DS inverter kune zvakanakira.
1. Mutengo wekushandisa kuvaka:
Seti ye8KW system kana kushandiswa kwe5KW +3KW kana 4KW +4KW modhi inverter mutengo ichave yakatenderedza 5000 +, nepo kushandiswa kweNatomic NAC8K-DS single-phase inverter, mutengo uri kutenderera mazana mana +. Yakabatanidzwa neAC tambo, tambo yeDC, bhokisi rekubatanidza uye mitengo yekuisa yevashandi, 8KW sisitimu inoshandisa Natto simba NAC8K-DC 8KW inverter, seti yemasisitimu inogona kuchengetedza ingangoita chiuru nemazana mashanu yuan mumutengo.
2. Kutarisisa uye mushure mekutengesa zvakanakira:
Uchishandisa ma inverters maviri, vashandisi vazhinji vasiri nyanzvi havazive kugadzira iyo data yekugadzira simba, uye havazive chaizvo kuti ingani simba rinogadzirwa, uye maviri inverter data inokonzeresa kunetsa kuti muisi averenge chizvarwa chemagetsi. Iine Natco NAC8K-DS inverter, iyo data yekugadzira magetsi yakajeka uye iri nyore kunzwisisa.
Natong Energy 8KW single-phase smart PV inverter yakashongedzerwawo ine simba rekutarisa system. Mushure mekunge mushandisi anyoresa, iyo smart hosting inogona kuitika. Vashandisi havafanire kutarisa mamiriro eiyo inverter vega. Mushure mekunge inverter yataura kukanganisa, mutengi anogona kugashira otomatiki kukurumidza pane nharembozha terminal. Panguva imwecheteyo, vashandi veNatong mushure mekutengesa-basa vanogamuchirawo kekutanga. Kune ruzivo rwekukundikana, tora danho rekubata mutengi kugadzirisa dambudziko, kugadzirisa dambudziko uye kuchengetedza purofiti yemutengi.
3. Zvakanakira kugadzirwa kwemagetsi kushanda zvakanaka:
1) .The voltage uye frequency yemaruwa asina simba grids haana kugadzikana. Parallel yekubatanidza yeakawanda inverters inogona kukonzera nyore resonance, kukwira kwevoltage, uye mamwe mamiriro akaomarara. Iyo yakafanana resonance yemichina yakawanda pasi pemamiriro asina simba etiweki ichaita kuti kubuda kweiyo inverter kuite oscillate, uye ruzha rusina kujairika rweinductor ruchachinja; iyo inobuda maitiro ichave yakashata, uye inverter ichave yakanyanyisa uye yakanyanyisa kubva kunetiweki, izvo zvichaita kuti inverter imire uye inokanganisa purofiti yemutengi. Mushure meiyo 8KW sisitimu yatora Natto NAC8K-DS, aya mamiriro anozonyatso kuvandudzwa.
2) .Kuenzaniswa nemhando dze5KW + 3KW kana 4KW + 4KW, KW system inoshandisa chete AC cable yeNAC8K-DS inverter, iyo inoderedza kurasikirwa uye inowedzera kugadzirwa kwemagetsi.
8KW system simba rekugadzira fungidziro (muJinan, Shandong Province semuenzaniso):
Makumi matatu nenhanhatu 265Wp yakakwirira-inoshanda zvikamu yakaiswa, ine yakazara yakaiswa inokwana 7.95 KW. Kushanda kweSystem = 85%. Chiedza che data chinobva kuNASA chinoratidzwa mutafura inotevera. Avhareji yenguva yezuva nezuva muJinan i4.28*365=1562.2 maawa.
Chikamu chinodzikira ne2.5% mugore rekutanga uyezve chinodzikira ne0.6% gore rega rega. Iyo 8KW sisitimu inogona kuverengerwa uchishandisa 8KW single-motor inverter, NAC8K-DC, ine cumulative chizvarwa chemagetsi chinosvika mazana maviri nemakumi mana ezviuru kWh mumakore makumi maviri nemashanu.
kupedzisa:
Pakuisa 8KW system, kushandiswa kwe8KW single-phase inverter kana ichienzaniswa neyechinyakare nzira ye5KW + 3KW kana 4KW + 4KW modhi ine mabhenefiti makuru mumutengo wekutanga wekuvaka, mushure mekutengesa kutarisa mushure mekutengesa, uye goho rekugadzira magetsi. .
