Ta yaya inverter mai haɗin grid ke cimma ruwa na yanzu cikin grid?

Inverters suna da matukar mahimmanci a tsarin makamashi na zamani, musamman a cikin tsarin makamashi mai sabuntawa. Babban aiki na inverter shine don canza halin yanzu kai tsaye da aka samar ta hanyar tushen wutar lantarki ta DC kamar panel na photovoltaic, man fetur, ko baturin lithium zuwa madaidaicin halin yanzu wanda ya dace da grid kuma ya haɗa shi zuwa grid.Yadda za a gane halin yanzu a cikin grid ya zama matsala wanda mutane da yawa suna damuwa game da wannan tsari. grid-connected photovoltaic inverters, man fetur cell, ko lithium baturi, kazalika da halin yanzu iyakance aiki na inverter.

1. Ta wace hanya ce inverter mai haɗin grid ke cimma ruwa na yanzu zuwa grid?

A Grid-da alaka inverter ta muhimmanci rawa hada da maida DC cikin AC da kuma tabbatar da cewa fitarwa AC za a iya ciyar smoothly a cikin grid.Voltage matching da mita aiki tare su ne aiki ka'idojin wani inverter.The AC ƙarfin lantarki generated da inverter bukatar ya zama m cikin sharuddan amplitude, mita, da kuma lokaci tare da grid irin ƙarfin lantarki a cikin wutar lantarki a AC. grid, to ba zai iya sassauta kwararar da ke gudana a cikin grid ba kuma yana iya shafar kwanciyar hankali na ƙarshen.

Gudun halin yanzu yana biye da ainihin ka'idar yuwuwar bambance-bambance: kawai lokacin da akwai bambancin ƙarfin lantarki tsakanin maki biyu na iya gudana a halin yanzu daga wurin da ƙarfin lantarki yana da girma zuwa wurin da yanayin yanzu yake low. A takaice dai, don grid-connected inverter, yana nufin fitarwa AC ƙarfin lantarki na inverter yana buƙatar kiyaye wani takamaiman yuwuwar bambanci daga grid voltage.Specifically, lokacin da fitarwa ƙarfin lantarki a cikin grid na yanzu zai gudana daga cikin wutar lantarki fiye da na yanzu. grid; Lokacin da wutar lantarki ta fi ƙarfin ƙarfin wutar lantarki na inverter, na yanzu ba zai gudana a cikin grid ba, kuma inverter yana buƙatar daidaita ƙarfin fitarwa don tabbatar da cewa halin yanzu zai iya shiga cikin grid ba tare da matsala ba.

Bugu da ƙari, dole ne ya bi diddigin mita da lokaci na grid a cikin ainihin lokaci don tabbatar da aiki tare. Halin halin yanzu na grid da fitarwa na yanzu na inverter ya kamata ya kiyaye mita da lokaci guda ɗaya, ta yadda lokacin da halin yanzu ke gudana a cikin grid, ba zai haifar da wani bambanci na lokaci wanda zai haifar da sauye-sauyen grid ba. Saboda haka, inverter yana tabbatar da fitarwa AC na iya gudana akai-akai cikin grid ta hanyar daidaita ƙarfin lantarki, mita, da lokaci.

2.Shin yuwuwar ko yuwuwar bambance-bambancen da ake buƙata don ƙirƙirar kwararar halin yanzu cikin grid?
Haka ne, da gaske ana tafiyar da kwararar wutar lantarki ne ta hanyar yuwuwar bambanci ko bambanci. Bambanci mai yuwuwa shine bambanci tsakanin maɗaukaki biyu, kuma bambancin ƙarfin lantarki yana nufin bambancin ƙarfin lantarki tsakanin maki biyu. A cikin aikace-aikacen inverter mai haɗin grid, bambancin wutar lantarki tsakanin inverter da grid yana ƙayyade alkiblar gudanawar yanzu. Sai kawai lokacin da akwai wani bambanci mai yuwuwa tsakanin ƙarfin fitarwa na inverter da wutar lantarki na grid, halin yanzu zai gudana zuwa grid.Mai canza wutar lantarki yana ba da tabbacin cewa wannan bambancin wutar lantarki yana cikin kewayon da ya dace ta hanyar daidaita ƙarfin wutar lantarki don saduwa da manufarsa na ƙyale halin yanzu zuwa grid.

3.Ko inverter mai haɗin grid na photovoltaic zai iya haɗawa da tantanin mai ko baturin lithium da aka ɗauka a ƙasa don gane ƙarfin grid:
Za'a iya haɗa masu inverters masu haɗawa da grid na hoto ba kawai zuwa tsarin panel na photovoltaic ba har ma da wasu nau'o'in wutar lantarki na DC, kamar man fetur ko baturan lithium, don samar da wutar lantarki da aka haɗa da grid.Ainihin ka'idar aiki iri ɗaya ce: kai tsaye na yanzu yana canzawa zuwa sauyawa na yanzu wanda ya dace da grid ta hanyar inverter.

Halayen fitarwa na ƙwayoyin man fetur da baturan lithium suna kama da na sel na photovoltaic: duka biyu suna ba da wutar lantarki na DC, amma wutar lantarki da fitarwa na yanzu na iya zama daban-daban. A al'ada, ƙarfin wutar lantarki na man fetur yana da tasiri sosai ta hanyar canjin nauyin, kuma ƙarfin baturi na lithium na iya canzawa tare da yanayin caji da yanayin lafiyar baturi. Sabili da haka, lokacin da waɗannan tsarin makamashi ke mu'amala da grid, mai inverter yana buƙatar isasshen sassauci wajen daidaita wutar lantarki da fitarwa na yanzu don ya iya daidai da ƙarfin lantarki, mita, da lokacin grid.

Gabaɗaya magana, ana iya haɗa masu inverters masu haɗin grid na hotovoltaic zuwa grid tare da tsarin batir mai man fetur da tsarin batirin lithium, muddin mai inverter zai iya juyar da halin yanzu kai tsaye daga maballin wuta daban-daban zuwa madaidaicin halin yanzu wanda ya dace da grid kuma yana iya jure ƙalubalen sauyin baturi ko fitarwar tantanin mai.

4.Lokacin da grid-connected ikon samar da aka gane, iya inverter iyakance halin yanzu?
Ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun lokaci shine muhimmin aiki na inverter mai haɗin grid, musamman a cikin tsarin samar da wutar lantarki.Inverter zai iya kula da halin yanzu da ƙarfin wutar lantarki na grid kuma ya cimma iyakar halin yanzu ta hanyar daidaita wutar lantarki.Lokacin da baturi ya yi caji sosai ko kuma ƙarfin wutar lantarki yana da girma, mai juyawa ta atomatik yana daidaita fitarwa don kauce wa lalacewa da yawa na na'ura na wutar lantarki.

Ayyukan iyakance na halin yanzu, wanda aka bayar a cikin inverter, yana sarrafa shi a ciki tare da algorithm ta hanyar da fitarwa na yanzu ba zai wuce iyakar da grid ya ba da izini ba.Misali, lokacin da canjin wutar lantarki ko canje-canjen kaya ya faru a cikin grid, mai canzawa ta atomatik yana rage ikon fitarwa don kauce wa sauye-sauyen da ba dole ba a halin yanzu da kuma kula da kwanciyar hankali na grid.

A wasu kalmomi, aikin iyakance na yanzu na inverter yana tabbatar da cewa ana kiyaye aminci da kwanciyar hankali a cikin grid ɗin wutar lantarki kuma yana hana wuce gona da iri na grid ɗin wuta ko lalacewar kayan aiki wanda zai iya haifar da wuce kima na halin yanzu na inverter.

The grid-connected inverter yana aiki ta hanyar daidaita ƙarfin fitarwa, mita, da lokaci don tabbatar da an daidaita shi tare da wutar lantarki na grid, saboda haka yana ba da damar kwararar halin yanzu a cikin grid.Ya dogara da yuwuwar bambanci ko bambancin ƙarfin lantarki, kuma shine lokacin da na yanzu zai gudana cikin kwanciyar hankali a cikin grid. ba kawai za a haɗa zuwa grid tare da photovoltaic panel amma kuma DC ikon kafofin kamar man fetur Kwayoyin da lithium baturi.Saboda haka, da inverter ya zama adaptable isa don magance hawa da sauka daga daban-daban ikon kafofin. A karshe, da halin yanzu iyakance aiki na inverter iya yadda ya kamata hana grid load daga zama ma girma, da kuma tabbatar da aminci da kwanciyar hankali na grid samar.
