Indlela yokukhetha unxibelelwano lwesikhululo samandla e-photovoltaic?

Xa kwakhiwa inkqubo yeplanti ye-photovoltaic yorhwebo, ukukhethwa kwee-inverters akuchaphazeli nje ukusebenza kokuveliswa kwamandla kodwa kuchaphazela ngokuthe ngqo ukusebenza okuzinzileyo kunye nolawulo oluhlakaniphile lwalo lonke umbane wamandla. Njengoko izixhobo eziphambili ezidibanisa iimodyuli ze-photovoltaic, iinkqubo zokugcina amandla, kunye negridi, i-inverters yenza imisebenzi emininzi, kubandakanywa ukuguqulwa kwamandla, ukuhanjiswa kwedatha kunye nokulawula unxibelelwano. Isisombululo esifanelekileyo sonxibelelwano sihlala sinquma ukukhululeka kunye nesantya sokuphendula emva kokwakhiwa kunye nokugcinwa kwezityalo zamandla e-photovoltaic. Okwangoku, iindlela zonxibelelwano ze-inverter eziqhelekileyo ziquka i-4G / 5G, i-WiFi, i-RS485, kunye ne-PLC, nganye ineempawu zayo, ifuna ukhetho olusekelwe kwiimfuno ezikhethekileyo zeprojekthi.

Isisombululo sonxibelelwano lwe-4G/5G, kunye ne "plug-and-play, akukho wiring efunekayo" inzuzo, yamkelwa ngokubanzi kwiiprojekthi ze-photovoltaic ezincinci kunye neziphakathi, ezifanelekileyo ngokukhethekileyo kwiindawo zasezidolophini ezinophawu oluhle. Nangona kunjalo, ukusilela kwabo kukwabonakala, njengokuthembela kuthungelwano lwabaqhubi kunye nesidingo sokuhlaziya izicwangciso zedatha emva kweminyaka emihlanu, nto leyo ethintela ukuphumelela kweendleko kwiiprojekthi ezithile zexesha elide.

Unxibelelwano lwe-WiFi lufaneleke ngakumbi kwiindawo zokuhlala kunye nezincinci zorhwebo kunye nezoshishino. Ngokuxhobisa ii-inverters ngeemodyuli ze-WiFi, imisebenzi yokubeka iliso inokuqhutywa ngenethiwekhi ekhoyo yomsebenzisi. Inzuzo kukuba akukho ntlawulo yedatha eyongezelelweyo eyenziwayo, kodwa i-disadvantage kukuba ifuna iimpawu zenethiwekhi eziphezulu kwaye iyakwazi ukuphazamiseka kwizinto ezifana nemozulu kunye nezakhiwo zokwakha.

Ngokwahlukileyo, unxibelelwano lwe-RS-485 lusebenzisa indlela ye-wiring ye-"daisy-chain" ukuphumeza ukulayishwa kwedatha edibeneyo evela kwii-inverters ezininzi, enikezela uzinzo oluphezulu kakhulu kunye nokuchasana nokuphazamiseka, okwenza ukuba ilungele iiprojekthi zezorhwebo kunye nezoshishino.

Unxibelelwano lwe-PLC luhambisa idatha ngokusebenzisa iintambo zamandla ezikhoyo ngaphandle kokufuna i-wiring eyongezelelweyo, ngaloo ndlela igcina izinto eziphathekayo kunye neendleko zokwakha ngelixa ivumela ukuhanjiswa ngokufanelekileyo kwedatha enkulu yedatha, okwenza ukuba ifaneleke kwizityalo zamandla ze-photovoltaic ezisemgangathweni ezinkulu kunye ne-step-up grid-connected systems. Nangona kunjalo, unxibelelwano lwe-PLC lukwanayo nemida ethile, njengobuntununtunu kuphazamiseko lwe-transformer kunye neemfuno eziphezulu zommandla wamandla.

Ngokuqinisekileyo, izisombululo zonxibelelwano ziyinxalenye yemilinganiselo yokukhetha i-inverter. Ubuchwephesha boyilo lwe-inverter, ukuhambelana konxibelelwano, kunye nobuchule bokudibanisa inkqubo zizinto eziphambili kwiikhrayitheriya zovavanyo. Uthotho lweqela leHuijue lwe iimveliso ze-inverter yenzelwe imigangatho yomgangatho wemizi-mveliso, exhasa ulungelelwaniso lweemeko zorhwebo kunye nezoshishino, kunye nokugcinwa kwendawo ekude nge-app kunye nokubeka iliso okuphakathi ngojongano lwewebhu. Iimveliso ziphinda zidibanise abalawuli beMPPT, iiyunithi zokufumana idatha ezihlakaniphile, kunye neqonga lokulawula elikude, ukufezekisa ukuhlanganiswa kwenkqubo epheleleyo ukusuka ekuqokeleleni amandla ukuya ekuhanjisweni kwedatha. Ngokukodwa kwiiprojekthi ezinkulu, ukuhlanganiswa okunzulu kwee-inverters ze-Huijue kunye neenkqubo zokugcina amandla zenza abasebenzisi bafezekise ngakumbi ukuguquguquka kwe-photovoltaic-storage integration schedulation, ngaloo ndlela kuphuculwe ukusebenza kakuhle kwamandla kuzo zombini isizukulwana kunye namacala okusebenzisa.

Izityalo zamandla e-Photovoltaic akufuneki zilandele ukusebenza kakuhle kokuveliswa kwamandla kodwa zibeke phambili ukulawulwa kunye nokhuseleko lokusebenza kwexesha elide. Ukukhetha inkqubo ye-inverter exhasa iindlela ezininzi zonxibelelwano, inamandla okudibanisa obukrelekrele, kunye nokuqinisekisa umgangatho wemveliso othembekileyo kuya kuphucula kakhulu ulawulo olusebenzayo kunye nokusebenza komzi-mveliso wamandla.

Iqela le-Huijue, kunye neminyaka yalo yobuchwephesha kunye nokuqokelela kobugcisa kwiinkqubo zokugcina amandla e-photovoltaic kunye nokwakhiwa kwendawo yesikhululo sesiseko, iye yaba liqabane elikhethiweyo kumashishini amaninzi, iipaki zemizi-mveliso, kunye neeprojekthi zamandla. Ukuze ufumane iinkcukacha ezithe vetshe, nceda uzive ukhululekile ukuqhagamshelana nathi ngolwazi oluthe vetshe!
