Grid-yakabatana PV yakabatana sei kune grid?

Mumamiriro ezvinhu ekuchinja kwemazuva ano, photovoltaic simba rekugadzira, sechimiro chakachena uye chinovandudzwa chesimba, chiri kushandiswa zvakanyanya uye zvakanyanya. Iyo grid-yakabatana cabinet ye photovoltaic power station ndiyo yakakosha midziyo yekubatanidza photovoltaic system uye magetsi grid, uye kukosha kwayo kunozviratidza.

Kutanga, iyo nheyo yekushanda yegridhi-yakabatana cabinet ye photovoltaic power station
Kushandura simba remagetsi uye kutumira
Solar panels mu photovoltaic power plant inoshandura simba rezuva kuita rakananga ikozvino. Mushure mekunge DC inounganidzwa kuburikidza nebhokisi rebhazi, inopinda inverter. Iyo inverter inoshandura yakananga ikozvino kune alternating ikozvino, uye yayo inobuda inochinjisa ikozvino ine yakafanana frequency uye chikamu segedhi remagetsi.
Iyo AC simba inoshandurwa neinverter inopinda grid-yakabatana cabinet ye photovoltaic power station. Iyo yedunhu breaker uye yekuzviparadzanisa switch mune grid-yakabatana kabati vane basa rekudzora nzira yekufambisa yesimba remagetsi. Kana zvinhu zvose zvakajairika, muvharidzi wedunhu akavharwa, uye ikozvino inoshandura inotumirwa kune grid kuburikidza negridhi cabinet.

Kuita basa rekudzivirira
Kudzivirirwa kwakanyanya: Kana iyo yazvino ichipfuura kukosha kwakatarwa, iyo overcurrent kudzivirira mudziyo inokurumidza kuita kuti icheke dunhu. Izvi zvinowanzoitika kuburikidza neshanduro yemazuva ano kuti ione ukuru hwemazuva ano, apo ikozvino inodarika chikumbaridzo chakaiswa, ichikonzera rwendo rwekutenderera.
Overvoltage protection: Kana iyo magetsi grid voltage yakawandisa, iyo overvoltage yekudzivirira mudziyo ichatanga kudzivirira iyo midziyo kubva mukukuvadzwa nekuda kwekuwedzeredza. Overvoltage dziviriro inogona kuona iyo magetsi grid voltage kuburikidza nevoltage transformer, kana voltage ichipfuura kukosha kweseti, kukonzeresa rwendo rwekutyora kwedunhu kana kutumira chiratidzo chealarm.
Undervoltage protection: Kusiyana nekudzivirira kwepamusoro, kana grid voltage yanyanya kuderera, iyo undervoltage yekudzivirira mudziyo ichashanda kuchengetedza yakagadzikana kushanda kwemidziyo uye grid. Saizvozvo, undervoltage dziviriro zvakare inoona iyo magetsi grid voltage kuburikidza nevoltage transformer, uye inokonzeresa inopindirana yekudzivirira chiitiko kana voltage yakadzikira pane yakatarwa kukosha.
Kudzivirirwa kwenguva pfupi: Kana kukanganisa-pfupi kunoitika munharaunda, chidziviriro chepfupi chekudzivirira chinobva chacheka dunhu kuitira kudzivirira kuwedzera kwekukanganisa. Kudzivirirwa kwedunhu pfupi kunowanzo kuwanikwa nemafusi anokurumidza kana mavhiriki edunhu.

Monitoring uye kutonga mabasa
Iyo grid-yakabatana cabinet ye photovoltaic power station yakashongedzerwa nezviridzwa zvakasiyana-siyana uye masensa echokwadi-nguva yekutarisa voltage, ikozvino, simba, frequency uye mamwe ma paramita. Aya ma paramita anogona kuratidzwa kune anoshanda kuburikidza nechiratidziro chiratidziro kana kure kure yekutaurirana system kuitira kuti unzwisise panguva yakakodzera mamiriro ekushanda eiyo photovoltaic power station.
Iyo yekudzora sisitimu inogona kudzora kure uye kugadzirisa iyo photovoltaic magetsi chiteshi zvinoenderana neinotariswa ma paramita. Semuenzaniso, kana iyo grid voltage yakanyanyisa, simba rinobuda re photovoltaic power station rinogona kuderedzwa kuburikidza nehurongwa hwekutonga; Kana iyo grid frequency isina kugadzikana, iyo inobuda frequency ye inverter inogona kugadziridzwa kuti irambe inoenderana neiyo grid frequency.
Chechipiri, nzira yekubatanidza yegridhi-yakabatana cabinet ye photovoltaic power station uye girasi remagetsi

Yakananga grid yekubatanidza
Yakananga grid yekubatanidza ndiyo yakajairika mhando yekubatanidza. Mune iyi nzira yekubatanidza, grid-yakabatana kabati ye photovoltaic power station yakabatana zvakananga kune yepakati kana yakaderera voltage mutsara wemagetsi grid kuburikidza ne circuit breaker, isolation switch uye zvimwe zvigadzirwa.
Zvakanakira yakananga grid yekubatanidza chimiro chakareruka, mutengo wakaderera uye kushanda kwakanyanya. Nekudaro, iyi yekubatanidza modhi ine zvakakwirira zvinodikanwa zvekubuda kwesimba remhando yephotovoltaic magetsi zviteshi, uye inofanirwa kusangana nehunyanzvi hwekuita uye zvinodiwa zvegridi. Panguva imwecheteyo, yakananga grid yekubatanidza inodawo kufunga kugadzikana uye kuvimbika kwegidhi remagetsi kudzivirira mhedzisiro yakaipa pane gidhi remagetsi.

Yakabatanidzwa kune grid ne transformer
The transformer yekubatanidza ndeyekubatanidza transformer pakati pe photovoltaic power station uye grid yemagetsi. Transformers inogona kusimudza kana kudzikisa simba rekubuda kwe photovoltaic power station kusvika pazinga revoltage rinoenderana negridi.
Kubatsira kwekubatanidza gidhi kuburikidza neshanduko ndeyekuti inogona kuvandudza yakabuda voltage ye photovoltaic power station, kuderedza kurasikirwa kwemutsara, uye zvakare kutamba basa rekuzviparadzanisa nekudzivirira. Zvisinei, iyi nzira yekubatanidza inodhura, inotora nzvimbo yakakura, uye kurasikirwa kweshanduko kuchaderedzawo kushanda kwese kwe photovoltaic power station.

Microgrid connection
Microgrid idiki simba sisitimu inoumbwa neakagoverwa magetsi emagetsi, simba rekuchengetedza mudziyo uye mutoro. Iyo photovoltaic power station inogona kubatanidzwa kune microgrid kuburikidza negridhi-yakabatana cabinet uye kuva chikamu che microgrid.
Iyo microgrid yekubatanidza nzira inogona kuvandudza kuvimbika uye kugadzikana kwe photovoltaic magetsi zviteshi, asi zvakare inogona kuwana kushandiswa kwakanaka uye kutonga kwesimba. Mune microgrids, photovoltaic plant inogona kushanda pamwe chete nemamwe magetsi akaparadzirwa kuti asangane nemitoro yemunharaunda. Kana iyo microgrid yakabatana kune iyo huru grid, iyo bidirectional kuyerera kwesimba inogonawo kuitika kuvandudza kushanda kwesimba rekushandisa.

Kuiswa uye kugadzirisa kwegridi-yakabatana kabati ye photovoltaic power station
Kuiswa zvinodiwa
Kuiswa kwegridi-yakabatana makabati emagetsi emagetsi ephotovoltaic anoenderana neakakodzera magetsi ekuchengetedza makodhi uye zviyero. Nzvimbo yekuisa inofanira kunge iri munzvimbo yakaoma, ine mhepo inofefetera iri nyore kushanda nekuchengetedza.
Iyo grid-yakabatana cabinet inofanira kuiswa yakachengeteka uye yakanyatsogadziriswa. Cables dzinofanirwa kubatanidzwa nemazvo kudzivirira kukanganisa kwakadai seshort circuit uye grounding.
Panguva yekuisa, kutarisisa kunofanirwa kubhadharwa kuchengetedza michina nemamita mune grid-yakabatana cabinet kudzivirira kukuvara. Panguva imwecheteyo, kuongororwa kwakasimba kwemagetsi uye kugadzirisa kunofanirwawo kuitwa kuti ive nechokwadi chekuti mabasa eiyo grid-yakabatana kabhineti yakajairika.
maintenance
Tarisa uye chengetedza iyo grid-yakabatana kabati yeiyo photovoltaic magetsi chiteshi nguva dzose, kusanganisira yekuchenesa michina, kutarisa tambo dzekubatanidza, kuyedza kudzivirira zvishandiso, nezvimwe.
Tarisa mamiriro ekushanda kwe grid-yakabatana cabinet. Kana chero mamiriro ezvinhu asina kunaka akawanikwa, zvibate nenguva. Semuenzaniso, kana muparadzi wedunhu akagumburwa, chiratidziro chechiridzwa chisina kujairika, nezvimwewo, chinofanira kuongororwa uye kugadziriswa nekukurumidza.
Midziyo uye zviridzwa zviri mugedhi-yakabatana kabati inoyerwa uye inoedzwa nguva nenguva kuti ive nechokwadi chechokwadi uye kuvimbika kwavo.
Simbisa kuchengetedzwa kwekuchengetedza kwegridhi-yakabatana makabati kudzivirira vasiri nyanzvi kubva kune misoperating kana kukuvadza michina.
