Idityaniswe njani i-PV yegridi kwigridi?

Kwimeko yenguqu yamandla yanamhlanje, ukuveliswa kwamandla e-photovoltaic, njengendlela ecocekileyo kunye nokuhlaziywa kwamandla, isetyenziswa ngokubanzi. Ikhabhinethi edibeneyo yegridi yesikhululo samandla e-photovoltaic sisixhobo esiphambili sokudibanisa inkqubo ye-photovoltaic kunye negridi yamandla, kwaye ukubaluleka kwayo kuyabonakala.

Okokuqala, umgaqo osebenzayo wekhabhinethi edibeneyo yegridi yesikhululo samandla e-photovoltaic
Ukuguqulwa kwamandla ombane kunye nokuhanjiswa
Iipaneli zelanga kwizityalo zamandla e-photovoltaic ziguqula amandla elanga abe ngumbane othe ngqo. Emva kokuba i-DC iqokelelwe ngebhokisi yebhasi, ingena kwi-inverter. I-inverter iguqula i-current ngqo kwi-alternating current, kwaye i-output yayo yokutshintsha i-current ine-frequency kunye nesigaba esifanayo njengegridi yamandla.
Amandla e-AC aguqulwa yi-inverter angena kwikhabhinethi edibeneyo yegridi yesikhululo samandla se-photovoltaic. Umqhekezi wesiphaluka kunye nokutshintsha okukodwa kwikhabhinethi edibeneyo yegridi inoxanduva lokulawula indlela yokuhambisa amandla ombane. Xa yonke into iyinto eqhelekileyo, i-breaker circuit ivaliwe, kwaye i-alternating current idluliselwa kwigridi ngekhabhinethi yegridi.

Ukuphunyezwa komsebenzi wokukhusela
Ukukhusela ngaphezulu: Xa i-current idlula ixabiso elimiselweyo, ifowuni yokukhusela i-overcurrent iya kwenza ngokukhawuleza ukunqumla isiphaluka. Oku kudla ngokusetyenziswa kwe-transformer yangoku ukufumanisa ubungakanani bangoku, xa i-current idlula i-threshold ebekiweyo, ibangela uhambo lwe-circuit breaker.
Ukhuseleko lokugqithiswa kombane: Xa i-voltage yegridi yamandla iphezulu kakhulu, isixhobo sokukhusela i-overvoltage siya kuqalisa ukukhusela izixhobo ukuba zingonakaliswe ngenxa yokugqithisa. Ukukhuselwa kwe-overvoltage kunokubona i-voltage yegridi yamandla ngokusebenzisa i-voltage ye-voltage, xa i-voltage idlula ixabiso elimiselweyo, qalisa uhambo lwe-breaker circuit okanye uthumele i-alarm signal.
Ukukhuselwa ngaphantsi kwamandla: Ngokuchasene nokukhuselwa kwe-overvoltage, xa i-voltage yegridi iphantsi kakhulu, isixhobo sokukhusela i-undervoltage siya kusebenza ukukhusela ukusebenza okuzinzile kwezixhobo kunye negridi. Ngokufanayo, ukukhuselwa kwe-undervoltage kwakhona kufumanisa i-voltage yegridi yamandla ngokusebenzisa i-voltage transformer, kwaye ibangela isenzo sokukhusela esihambelanayo xa i-voltage iphantsi kunexabiso elimiselweyo.
Ukhuseleko lwendlela emfutshane: Xa i-short-circuit iphutha lenzeka kwisiphaluka, isixhobo sokukhusela i-short-circuit siya kunqumla ngokukhawuleza isiphaluka ukuthintela ukwandiswa kwesiphoso. Ukukhuselwa kweesekethe ezimfutshane ngokuqhelekileyo kufezekiswa ngeefuse ezikhawulezayo okanye i-breakers circuit.

Ukubeka iliso kunye nokulawula imisebenzi
Ikhabhinethi edibeneyo yegridi yesikhululo samandla e-photovoltaic ixhotyiswe ngezixhobo ezahlukeneyo kunye neenzwa zokujonga ixesha langempela lombane, okwangoku, amandla, ukuphindaphinda kunye nezinye iiparitha. Ezi parameters zinokuboniswa kumqhubi ngokusebenzisa isikrini sokubonisa okanye inkqubo yokunxibelelana ekude ukuze uqonde ngexesha elifanelekileyo imeko yokusebenza yesikhululo samandla e-photovoltaic.
Inkqubo yokulawula inokulawula kude kwaye ilungise isikhululo samandla e-photovoltaic ngokweeparamitha ezibekwe esweni. Ngokomzekelo, xa i-voltage yegridi iphezulu kakhulu, amandla okukhutshwa kwesikhululo samandla e-photovoltaic anokunciphisa ngokusebenzisa inkqubo yokulawula; Xa i-frequency yegridi ingazinzanga, i-frequency ye-output ye-inverter inokulungiswa ukuze igcinwe ihambelana ne-frequency yegridi.
Okwesibini, imodi yokudibanisa yekhabhinethi edibeneyo yegridi yesikhululo samandla e-photovoltaic kunye negridi yamandla

Uqhagamshelwano lwegridi ethe ngqo
Uqhagamshelwano lwegridi oluthe ngqo lolona hlobo luxhaphakileyo loqhagamshelwano. Kule ndlela yokudibanisa, ikhabhinethi edibeneyo yegridi yesikhululo samandla e-photovoltaic ixhunywe ngokuthe ngqo kumgca we-voltage ophakathi okanye ophantsi wegridi yamandla ngokusebenzisa i-breaker circuit, i-switch switch kunye nezinye izixhobo.
Iingenelo zokuxhunyelelwa kwegridi ngokuthe ngqo zisakhiwo esilula, ixabiso eliphantsi kunye nokusebenza okuphezulu. Nangona kunjalo, le ndlela yokudibanisa ineemfuno eziphezulu zomgangatho wamandla ophumayo wezikhululo zamandla e-photovoltaic, kwaye kufuneka zihlangabezane neenkcukacha zobugcisa kunye neemfuno zegridi. Ngexesha elifanayo, uxhulumaniso lwegridi oluthe ngqo lufuna ukuqwalasela ukuzinza kunye nokuthembeka kwegridi yamandla ukuphepha imiphumo emibi kwigridi yamandla.

Idityaniswe kwigridi nge-transformer
Uqhagamshelwano lwe-transformer kukudibanisa i-transformer phakathi kwesikhululo samandla e-photovoltaic kunye negridi yamandla. Abaguquli banokunyusa okanye banciphise i-voltage ephumayo yesikhululo samandla e-photovoltaic ukuya kwinqanaba lombane elihambelana negridi.
Inzuzo yokudibanisa igridi ngokusebenzisa i-transformer kukuba inokuphucula i-voltage ephumayo yesikhululo samandla se-photovoltaic, ukunciphisa ukulahleka komgca, kwaye iphinde idlale indima yokuzimela kunye nokukhusela. Nangona kunjalo, le ndlela yokudibanisa iyabiza, ithatha indawo enkulu, kwaye ukulahlekelwa kwe-transformer kuya kunciphisa kwakhona ukusebenza kakuhle kwesikhululo samandla e-photovoltaic.

Uqhagamshelwano lweMicrogrid
I-Microgrid yinkqubo encinci yamandla eyenziwe ngumbane osasazwayo, isixhobo sokugcina amandla kunye nomthwalo. Isikhululo samandla e-photovoltaic sinokudibaniswa kwi-microgrid ngekhabhinethi edibeneyo yegridi kwaye ibe yinxalenye ye-microgrid.
Indlela yokudibanisa i-microgrid inokuphucula ukuthembeka kunye nokuzinza kwezikhululo zamandla e-photovoltaic, kodwa nazo zinokufezekisa ukusetyenziswa ngokufanelekileyo kunye nokulawulwa kwamandla. Kwii-microgrids, izityalo ze-photovoltaic zinokusebenza ngokubambisana kunye neminye imithombo yamandla esasazwayo ukuhlangabezana neemfuno zemithwalo yendawo. Xa i-microgrid iqhagamshelwe kwigridi ephambili, ukuhamba kwe-bidirectional yamandla nako kunokuphunyezwa ukuphucula ukusebenza kakuhle kokusetyenziswa kwamandla.

Ukufakwa kunye nokugcinwa kwekhabhinethi edibeneyo yegridi yesikhululo samandla e-photovoltaic
Iimfuno zofakelo
Ukufakwa kweekhabhinethi eziqhagamshelwe kwigridi yezikhululo zamandla e-photovoltaic ziya kuhambelana neekhowudi ezifanelekileyo zombane kunye nemigangatho. Indawo yokufakela kufuneka ibe kwindawo eyomileyo, engenamoya ekulula ukuyisebenzisa nokugcina.
