Ungawengeza kanjani amabhethri kusistimu yelanga eboshwe ngegridi—AC Coupling

Ukwengeza amabhethri kusistimu sonozungezilanga eboshwe ngegridi ekhona kuyindlela enhle yokwandisa ukuzimela futhi okungenzeka wonge ezindlekweni zamandla. Nawu umhlahlandlela ojwayelekile wokuthi ungangeza kanjani amabhethri ekusetheni kwakho kusetshenziswa imizuliswano yelanga:
Indlela #1: Ukuhlanganisa i-AC
Ukuze ama-inverter aboshwe ngegridi asebenze, athembele kugridi yamandla, eqapha ngokuqhubekayo i-voltage yegridi kanye nemvamisa. Uma ichezuka ngaphezu kwamapharamitha asethiwe, ama-inverters ayavalwa njengesinyathelo sokuphepha.
Kusistimu ehlanganisiwe ye-AC, i-inverter eboshwe ngegridi ixhunywe ne-off-grid inverter kanye nebhange lebhethri. I-inverter ye-off-grid isebenza njengomthombo wamandla wesibili, empeleni ikhohlisa i-inverter eboshwe ngegridi ukuze iqhubeke isebenza. Lokhu kusetha kuvumela ukushajwa kwebhethri kanye nokusebenza kwempahla ebalulekile ngisho nalapho ugesi ucisha.
Inketho engcono kakhulu yokuhlanganisa i-AC i-Deye, i-Megarevo, i-Grwatt noma i-Alicosolar.
I-AC Coupling inikeza izinzuzo ezimbalwa:

Ukuqina Okuthuthukisiwe: Ukuhlanganisa i-AC kuthuthukisa ukuqina kwesistimu ngokuvumela ukusebenza kwempahla ebalulekile kanye nokushajwa kwebhethri ngesikhathi sokunqamuka kukagesi, kuqinisekisa ukutholakala kwamandla okungaphazamiseki.
Ukuvumelana Nezimo Okunyukile: Inikeza ukuguquguquka ekwakhiweni kwesistimu ngokunika amandla ukuhlanganiswa kwezingxenye ezingaphandle kwegridi namasistimu aboshwe ngegridi, enikeza izinketho ezengeziwe zokuphathwa kwamandla nokusetshenziswa.
Ukuphathwa Kwezamandla Okuthuthukisiwe: Ngokuhlanganisa umthombo wamandla wesibili kanye nebhange lebhethri, ukuhlanganisa i-AC kuvumela ukuphathwa kwamandla okuthuthukisiwe, ukwandisa ukuzisebenzisela wena kanye nokunciphisa ukuthembela kugridi.
Ukuzimela Kwezamandla Okuthuthukisiwe: Abasebenzisi banganciphisa ukuncika kugridi futhi bazuze ukuzimela okukhulu kwamandla ngokusebenzisa amandla agciniwe asuka kumabhethri ngezikhathi zokutholakala kwegridi ephansi noma isidingo esikhulu samandla.
Ukusetshenziswa Okuphumelelayo Kwegridi: Ukuhlanganisa i-AC kuvumela ukusetshenziswa kahle kwama-inverter aboshwe ngegridi ngokuqinisekisa ukuthi ahlala esebenza ngisho nangesikhathi sokuphazamiseka kwegridi, ngaleyo ndlela kuthuthukisa ukutshalwa kwezimali kungqalasizinda eboshelwe igridi.
Sekukonke, ukuhlanganisa i-AC kuthuthukisa ukwethembeka kwesistimu, ukuguquguquka, nokuphathwa kwamandla, kunikeza abasebenzisi amandla amakhulu okunikezwa kwamandla abo kanye nokunciphisa ukuthembela emithonjeni yangaphandle ngesikhathi sokucima noma izikhathi zokufunwa kakhulu.

Ngenkathi ukuhlanganiswa kwe-AC kunikeza izinzuzo ezahlukahlukene, futhi kuveza ezinye izithiyo:

Ubunkimbinkimbi: Ukuhlanganisa i-AC kubandakanya ukuhlanganisa izingxenye eziboshwe ngegridi nezingekho kugridi, ezingakhuphula ubunkimbinkimbi besistimu. Ukufaka nokunakekela kungase kudinge ulwazi olukhethekile nobungcweti, okungase kuholele ezindlekweni eziphakeme.
Izindleko: Ukwengezwa kwezingxenye ezingaphandle kwegridi njengama-inverter namabhange ebhethri kungakhuphula kakhulu izindleko zangaphambili zohlelo. Lokhu kungenza ukuhlangana kwe-AC kungabi lula ngokwezimali kwabanye abasebenzisi, ikakhulukazi uma kuqhathaniswa nokusetha okulula okuboshwe ngegridi.
Ukulahleka Kokusebenza: Ukuhlanganisa i-AC kungethula ukulahlekelwa kokusebenza kahle uma kuqhathaniswa nokuhlanganisa okuqondile kwe-DC noma ukusethwa kwegridi evamile. Izinqubo zokuguqulwa kwamandla phakathi kwe-AC ne-DC, kanye nokushajwa nokushajwa kwebhethri, kungaholela ekulahlekeni kwamandla athile ngokuhamba kwesikhathi.
Okukhiphayo Okulinganiselwe Amandla: Iziguquli ze-off-grid namabhange ebhethri ngokuvamile anamandla alinganiselwe uma kuqhathaniswa nama-inverter aboshwe ngegridi. Lo mkhawulo ungase ukhawulele inani lamandla esistimu, kuthinte amandla ayo okusekela izinhlelo zokusebenza ezidingeka kakhulu noma imithwalo emikhulu.
Izinkinga Zokuhambisana: Ukuqinisekisa ukuhambisana phakathi kwezingxenye eziboshwe ngegridi nezingekho kugridi kungaba inselele. Ukungahambelani noma ukungezwani ku-voltage, imvamisa, noma izimiso zokuxhumana kungaholela ekungasebenzini kahle kwesistimu noma ekuhlulekeni.
Izithiyo Zokulawula Nezimvume: Amasistimu wokuhlanganisa we-AC angase abhekane nezidingo ezengeziwe zokulawula nezimvume uma kuqhathaniswa nokusetha okujwayelekile okuboshwe ngegridi. Ukuthobela amakhodi endawo kanye nemithethonqubo elawula ukufakwa ngaphandle kwegridi kungengeza inkimbinkimbi nesikhathi kuphrojekthi.
Naphezu kwalezi zinselele, ukuhlanganisa i-AC kusengaba inketho esebenzayo kubasebenzisi abafuna ukuqina okuthuthukisiwe, ukuzimela kwamandla, nokuguquguquka kumasistimu abo wamandla. Ukuhlela ngokucophelela, ukufakwa okufanele, nokunakekelwa okuqhubekayo kubalulekile ukuze kuncishiswe izihibe ezingaba khona futhi kwandiswe izinzuzo zokuhlanganisa i-AC.
