Menene photovoltaic, menene ajiyar makamashi, menene mai canzawa, menene inverter, menene PCS da sauran kalmomin shiga.
01, Ma'ajiyar makamashi da photovoltaic masana'antu biyu ne
Dangantakar da ke tsakanin su ita ce, tsarin hoto yana canza makamashin hasken rana zuwa makamashin lantarki, kuma tsarin ajiyar makamashi yana adana makamashin lantarki da aka samar da kayan aikin hoto. Lokacin da ake buƙatar wannan ɓangaren makamashin lantarki, ana jujjuya shi zuwa madaidaicin halin yanzu ta hanyar na'urar ajiyar makamashi don ɗaukar nauyi ko amfani da grid.
02, Bayanin mahimman kalmomi
Kamar yadda Baidu ya yi bayani: a rayuwa wasu lokatai suna buƙatar canza wutar AC zuwa wutar DC, wanda shine da'irar gyarawa, kuma a wasu lokuta, ya zama dole a canza wutar DC zuwa wutar AC. Wannan tsarin juzu'i mai dacewa da gyara ana bayyana shi azaman inverter circuit. Ƙarƙashin wasu sharuɗɗa, ana iya amfani da saitin da'irori na thyristor azaman da'ira mai gyarawa da da'irar inverter. Ana kiran wannan na'ura mai canzawa, wanda ya haɗa da masu gyara, inverters, masu canza AC, da masu canza DC.
Mu sake fahimta:
Turancin mai canzawa shine mai canzawa, wanda gabaɗaya ana gane shi ta hanyar kayan lantarki na lantarki, kuma aikinsa shine fahimtar watsa wutar lantarki. Bisa ga nau'ikan nau'ikan ƙarfin lantarki kafin da kuma bayan juyawa, an kasu kashi kamar haka:
DC/DC Converter, gaba da baya su ne DC, irin ƙarfin lantarki ne daban-daban, da aikin DC transformer
AC/DC Converter, AC zuwa DC, rawar da mai gyara
DC/AC Converter, DC zuwa AC, rawar da inverter
Mai canza AC/AC, mitoci na gaba da na baya sun bambanta, rawar mai sauya mitar
Baya ga babban da'irar (bi da bi, rectifier circuit, inverter circuit, AC convert circuit and DC convert circuit), mai musanya kuma yana buƙatar samun da'irar faɗakarwa (ko da'irar kewayawa) don sarrafa kunna kashe na'urar sauya wutar lantarki da zuwa gane da ka'idar makamashin lantarki, kula da kewaye.
Sunan Ingilishi na mai canza makamashin makamashi shine Tsarin Canjin Wuta, wanda ake kira PCS, wanda ke sarrafa tsarin caji da cajin baturi kuma yana yin canjin AC-DC. Ya ƙunshi mai jujjuya bidi'a na DC/AC da naúrar sarrafawa.
03, PCS gabaɗaya rarrabuwa
Ana iya raba shi daga masana'antu daban-daban guda biyu, photovoltaic da ajiyar makamashi, saboda ayyukan da suka dace sun bambanta:
A cikin masana'antar photovoltaic, akwai: nau'in tsakiya, nau'in kirtani, micro inverter
Inverter-DC zuwa AC: Babban aikin shine juyar da halin yanzu kai tsaye wanda aka canza ta hanyar hasken rana zuwa madaidaicin halin yanzu ta hanyar kayan aikin hoto, wanda za'a iya amfani dashi ta kaya ko haɗawa cikin grid ko adanawa.
Karkasa: ikon yin amfani da shi shine manyan tashoshin wutar lantarki na ƙasa, rarraba kayan aikin masana'antu da kasuwanci, kuma ƙarfin fitarwa gabaɗaya ya fi 250KW
Nau'in igiya: iyakokin aikace-aikacen manyan tashoshin wutar lantarki ne na ƙasa, rarraba hoto na masana'antu da kasuwanci (nau'in fitarwa gabaɗaya ƙasa da 250KW, kashi uku), photovoltaics na gida (ƙarar fitarwa ta ƙasa da ko daidai da 10KW, lokaci-lokaci ɗaya) ,
Micro-inverter: Ana rarraba iyakokin aikace-aikacen photovoltaic (ikon fitarwa na gabaɗaya bai wuce ko daidai da 5KW, mataki uku ba), photovoltaic na gida (ikon fitarwa gabaɗaya ya fi ko daidai da 2KW, lokaci-lokaci ɗaya)
Tsarin ajiyar makamashi sun haɗa da: babban ajiya, masana'antu da ajiyar kasuwanci,ajiyar gida, kuma za'a iya raba shi zuwa masu canza ma'ajin makamashi (ma'ajin ajiyar makamashi na al'ada, Hybrid) da injuna masu haɗaka
Canjin AC-DC: Babban aikin shine sarrafa caji da fitar da baturi. Wutar wutar lantarki ta DC da aka samar ta hanyar samar da wutar lantarki ta photovoltaic an canza zuwa ikon AC ta hanyar inverter. Ana canza canjin halin yanzu zuwa halin yanzu kai tsaye don caji. Lokacin da ake buƙatar wannan ɓangaren makamashin lantarki, ƙarfin wutar lantarki kai tsaye a cikin baturi yana buƙatar a canza shi zuwa madaidaicin halin yanzu (gaba ɗaya 220V, 50HZ) ta wurin mai canza makamashi don amfani da kaya ko haɗawa da grid. Wannan fitarwa ne. tsari.
Babban ajiya: tashar wutar lantarki ta ƙasa, tashar wutar lantarki mai zaman kanta, ƙarfin fitarwa gabaɗaya ya fi 250KW
Ma'ajiyar masana'antu da kasuwanci: ƙarfin fitarwa gabaɗaya bai kai ko daidai da 250KW ba
Ma'ajiyar gida: ƙarfin fitarwa gabaɗaya bai kai ko daidai da 10KW ba
Ma'ajin ajiyar makamashi na gargajiya: galibi suna amfani da tsarin haɗin gwiwar AC, kuma yanayin aikace-aikacen galibi manyan ajiya ne.
Hybrid inverter: galibi yana ɗaukar tsarin haɗin kai na DC, kuma yanayin aikace-aikacen shine galibin ajiyar gida
Duk-in-daya inverter: mai canza wutar lantarki + fakitin baturi, samfuran sun fi Tesla da Ephase
