I-PV exhunywe kugridi ixhunywe kanjani kugridi?

Esimweni soguquko lwanamuhla lwamandla, ukukhiqizwa kwamandla e-photovoltaic, njengendlela yamandla ahlanzekile futhi avuselelekayo, kuyasetshenziswa kabanzi. Ikhabhinethi exhunywe kugridi yesiteshi samandla e-photovoltaic iyisisetshenziswa esibalulekile sokuxhunywa kwesistimu ye-photovoltaic kanye negridi yamandla, futhi ukubaluleka kwayo kuyabonakala.

Okokuqala, isimiso sokusebenza sekhabhinethi exhunywe kugridi yesiteshi samandla e-photovoltaic
Ukuguqulwa kwamandla kagesi kanye nokudluliselwa
Amaphaneli elanga ezitshalweni zamandla e-photovoltaic aguqula amandla elanga abe wamanje oqondile. Ngemuva kokuthi i-DC iqoqwe ngebhokisi lebhasi, ingena ku-inverter. I-inverter iguqulela amandla amanje aqondile abe awamanje ashintshayo, futhi amandla ayo ashintshashintshayo aphumayo anemvamisa nesigaba esifanayo negridi yamandla.
Amandla e-AC aguqulwa yi-inverter angena kukhabhinethi exhunywe kugridi yesiteshi samandla se-photovoltaic. I-circuit breaker kanye ne-isolation switch kukhabhinethi exhunywe kugridi inesibopho sokulawula indlela yokudlulisa amandla kagesi. Uma yonke into ijwayelekile, i-breaker circuit ivaliwe, futhi i-alternating current idluliselwa kugridi ngokusebenzisa ikhabhinethi yegridi.

Ukuqaliswa komsebenzi wokuvikela
Ukuvikelwa okweqile: Uma i-current idlula inani elibekiwe, idivayisi yokuvikela i-overcurrent izothatha isinyathelo ngokushesha ukuze inqamule isekethe. Lokhu kuvame ukudlula i-transformer yamanje ukuze kutholwe usayizi wamanje, lapho i-current idlula i-threshold ebekiwe, okubangela uhambo lwe-circuit breaker.
Ukuvikelwa kwe-overvoltage: Uma i-voltage yegridi yamandla iphezulu kakhulu, idivayisi yokuvikela i-overvoltage izoqala ukuvimbela okokusebenza ukuthi konakaliswe ngenxa yokugcwala ngokweqile. Ukuvikelwa kwe-overvoltage kungathola i-voltage yegridi yamandla nge-voltage transformer, lapho i-voltage idlula inani elibekiwe, icuphe uhambo lwe-circuit breaker noma ithumele isignali ye-alamu.
Ukuvikelwa kwe-Undervoltage: Ngokuphambene nokuvikelwa kwe-overvoltage, lapho i-voltage yegridi iphansi kakhulu, idivayisi yokuvikela i-undervoltage izosebenza ukuze ivikele ukusebenza okuzinzile kwempahla kanye negridi. Ngokufanayo, ukuvikelwa kwe-undervoltage futhi kuthola i-voltage yegridi yamandla nge-voltage transformer, futhi kucuphe isenzo sokuvikela esihambisanayo lapho i-voltage iphansi kunevelu emisiwe.
Ukuvikelwa iDemo-wesifunda: Uma kwenzeka iphutha le-short-circuit kusekethe, idivayisi yokuvikela i-short-circuit izonqamula isekethe ukuvimbela ukwanda kwephutha. Ukuvikela isifunda esifushane ngokuvamile kufinyelelwa ngamafuse asheshayo noma ama-circuit breaker.

Imisebenzi yokuqapha nokulawula
Ikhabhinethi exhunywe kugridi yesiteshi samandla e-photovoltaic ifakwe amathuluzi ahlukahlukene kanye nezinzwa zokuqapha ngesikhathi sangempela se-voltage, yamanje, amandla, imvamisa neminye imingcele. Le mingcele ingaboniswa ku-opharetha ngesikrini sokubonisa noma isistimu yokuxhumana ekude ukuze uqonde ngesikhathi esifanele isimo sokusebenza sesiteshi samandla se-photovoltaic.
Uhlelo lokulawula lungakwazi ukulawula ukude futhi lulungise isiteshi samandla e-photovoltaic ngokuvumelana nemingcele egadiwe. Isibonelo, lapho i-voltage yegridi iphezulu kakhulu, amandla okukhipha esiteshini samandla e-photovoltaic angancishiswa ngesistimu yokulawula; Uma ifrikhwensi yegridi ingazinzile, imvamisa yokukhiphayo ye-inverter ingalungiswa ukuze ihlale ihambisana nefrikhwensi yegridi.
Okwesibili, imodi yokuxhuma yekhabhinethi exhunywe kugridi yesiteshi samandla se-photovoltaic kanye negridi yamandla

Uxhumano lwegridi eqondile
Ukuxhumeka kwegridi eqondile kuwuhlobo oluvame kakhulu lokuxhuma. Kule modi yokuxhuma, ikhabhinethi exhunywe kugridi yesiteshi samandla e-photovoltaic ixhunywe ngokuqondile emgqeni we-voltage ophakathi noma ophansi wegridi yamandla ngokusebenzisa i-breaker circuit, i-isolation switch kanye nezinye izinto zokusebenza.
Izinzuzo zokuxhuma kwegridi eqondile yisakhiwo esilula, izindleko eziphansi nokusebenza kahle okuphezulu. Kodwa-ke, le modi yokuxhuma inezidingo eziphezulu zekhwalithi yamandla okukhipha eziteshini zamandla e-photovoltaic, futhi kufanele ihlangabezane nokucaciswa kobuchwepheshe kanye nezidingo zegridi. Ngesikhathi esifanayo, ukuxhumana kwegridi eqondile nakho kudinga ukucabangela ukuzinza nokuthembeka kwegridi yamandla ukuze kugwenywe imiphumela emibi kugridi yamandla.

Ixhunywe kugridi nge-transformer
Ukuxhumana kwe-transformer ukuxhuma i-transformer phakathi kwesiteshi samandla se-photovoltaic kanye negridi yamandla. Ama-Transformer angakhuphula noma ehlise i-voltage ephumayo yesiteshi samandla e-photovoltaic aye ezingeni le-voltage elifana negridi.
Inzuzo yokuxhuma igridi nge-transformer yukuthi ingathuthukisa i-voltage yokuphuma kwesiteshi samandla se-photovoltaic, inciphise ukulahlekelwa komugqa, futhi idlale indima yokuzihlukanisa nokuvikela. Kodwa-ke, le ndlela yokuxhuma iyabiza, ithatha indawo enkulu, futhi ukulahlekelwa kwe-transformer kuzophinde kunciphise ukusebenza kahle okuphelele kwesiteshi samandla se-photovoltaic.

Ukuxhumeka kwe-Microgrid
I-Microgrid iwuhlelo lwamandla oluncane olwakhiwe ukunikezwa kwamandla asakazwayo, idivayisi yokugcina amandla kanye nomthwalo. Isiteshi samandla e-photovoltaic singaxhunywa ku-microgrid ngekhabhinethi exhunywe kugridi futhi sibe yingxenye yegridi encane.
Indlela yokuxhuma i-microgrid ingathuthukisa ukwethembeka nokuzinza kweziteshi zamandla e-photovoltaic, kodwa futhi ingafinyelela ukusetshenziswa okuphumelelayo nokuphathwa kwamandla. Kuma-microgrid, izitshalo ze-photovoltaic zingasebenza ngekhonsathi neminye imithombo yamandla esabalalisiwe ukuze ihlangabezane nezidingo zemithwalo yendawo. Uma i-microgrid ixhunywe kugridi eyinhloko, ukugeleza kwamandla okuqondiswa kabili kungase kubonakale ukuze kuthuthukiswe ukusebenza kahle kokusetshenziswa kwamandla.

Ukufakwa nokugcinwa kwekhabhinethi exhunywe kugridi yesiteshi samandla se-photovoltaic
Izidingo zokufaka
Ukufakwa kwamakhabhinethi axhunywe kugridi eziteshi zamandla e-photovoltaic kuzohambisana namakhodi nezindinganiso zokuphepha zikagesi ezifanele. Indawo yokufaka kufanele ibe sendaweni eyomile, engenawo umoya futhi kulula ukuyisebenzisa nokuyinakekela.
Ikhabhinethi exhunywe ngegridi kufanele ifakwe ngokuvikelekile futhi isekelwe kahle. Amakhebuli kufanele axhunywe ngendlela efanele ukuze agweme amaphutha njengokujikeleza okufushane kanye nokubeka phansi.
Phakathi nenqubo yokufaka, kufanele kuqashelwe ukuvikela izinto zokusebenza namamitha kukhabhinethi exhunywe kugridi ukuze kugwenywe umonakalo. Ngesikhathi esifanayo, ukuhlolwa okuqinile kukagesi kanye nokulungisa iphutha kufanele futhi kwenziwe ukuze kuqinisekiswe ukuthi imisebenzi yekhabhinethi exhunywe kugridi ijwayelekile.
ukugcinwa
Hlola futhi ulondoloze ikhabhinethi exhunywe kugridi yesiteshi samandla e-photovoltaic njalo, okuhlanganisa okokusebenza kokuhlanza, ukuhlola uxhumo lwekhebula, izisetshenziswa zokuvikela zokuhlola, njll.
Qaphela ukusebenza kwekhabhinethi exhunywe kugridi. Uma kutholakala noma yisiphi isimo esingajwayelekile, siphathe kusenesikhathi. Isibonelo, uma i-circuit breaker ikhubeka, isibonisi sensimbi asijwayelekile, njll., kufanele sihlolwe futhi silungiswe ngokushesha.
Amathuluzi namathuluzi kukhabhinethi exhunywe kugridi kuyalinganiswa futhi kuhlolwe njalo ukuze kuqinisekiswe ukunemba nokwethembeka kwazo.
Qinisa ukulawulwa kokuphepha kwamakhabethe axhunywe kugridi ukuze kuvinjelwe abangewona ochwepheshe ekusebenziseni kabi noma ukulimaza imishini.
