Kwintsimi yamandla amatsha, i-photovoltaic inverters kunye ne-inverters yokugcina amandla zizixhobo ezibalulekileyo, kwaye zidlala indima ebalulekileyo ebomini bethu. Kodwa yintoni kanye kanye umahluko phakathi kwezi zimbini? Siza kuqhuba uhlalutyo olunzulu lwala ma-inverters amabini ukusuka kwimiba yesakhiwo, umsebenzi, iimeko zesicelo, njl.
01 Umahluko kulwakhiwo
Okokuqala, ngokomgaqo, i-inverter sisixhobo esiguqula amandla e-DC kumandla e-AC. Isebenzisa iimpawu zokutshintsha kwezixhobo ze-semiconductor (ezifana ne-transistors ye-field effect okanye i-thyristors, njl.) ukulawula umbane wombane kunye nombane ngokutshintsha ngokukhawuleza, ngaloo ndlela ufezekise ukuguqulwa kwe-DC ukuya kwi-AC.
Umzobo we-Photovoltaic inverter topology
I-inverter yokugcina amandla (i-PCS) yingcamango ebanzi, ebandakanya ukuguqulwa kunye nokulawulwa kwamandla ombane ngokusebenzisa izixhobo zombane zombane ukuphumeza ukuhanjiswa kwamandla, ukuguqulwa kunye nokulawula. I-PCS ikakhulu ibandakanya i-rectifier, i-inverter, ukuguqulwa kwe-DC / DC kunye nezinye iimodyuli zemodyuli, apho imodyuli yokuguqula enye kuphela yamacandelo ayo.

02 Iimpawu
Ngokusebenzayo, i-photovoltaic inverter igxile ikakhulu ekuguquleni amandla eDC aveliswa ziiphaneli zesolar photovoltaic zibe ngamandla e-AC ukuze asetyenziswe kwigridi yamandla okanye kwizixhobo zombane. Ilungiselela amandla okuphuma kwe-solar photovoltaic array ngokusebenzisa iisekethe zangaphakathi kunye neemodyuli zokulawula, yenza uluhlu lweenkqubo kumandla e-DC aveliswa ngamapaneli e-photovoltaic, kwaye ekugqibeleni ivelise amandla e-AC ahlangabezana neemfuno zegridi yamandla.
Abaguquli bokugcina amandla bahlawula ingqwalasela engakumbi ekuguqulweni kweendlela ezimbini kunye nolawulo oluhlakaniphile lwamandla ombane. Ayiguquli kuphela amandla e-DC kumandla e-AC, kodwa ikwaguqula amandla e-AC kumandla e-DC okugcina. Ukongeza ekuqondeni i-DC kwi-AC yokuguqulwa, ikwaxhasa unxibelelwano lwe-BMS/EMS, ulawulo lwenqanaba leqela, ukunyuswa kwentlawulo kunye nomthamo wokukhupha, ulawulo oluzimeleyo lwasekhaya lokuchetywa kwencopho kunye nokuzaliswa kwentlambo, kunye nokucwangciswa okukrelekrele kwentlawulo kunye nokukhupha imisebenzi yokugcina amandla. inkqubo.
03 Iimeko zokusetyenziswa
Ngokweemeko zesicelo, ii-inverters ze-photovoltaic zisetyenziswa kakhulu kwiinkqubo zokuvelisa amandla elanga, njengeenkqubo ze-photovoltaic zasekhaya, iiprojekthi ze-photovoltaic zoshishino kunye nezorhwebo, kunye nezikhululo zamandla zomhlaba ezinkulu. Umsebenzi wayo ophambili kukuguqula amandla eDC enkqubo yokuvelisa amandla elanga abe ngamandla e-AC kwaye adibanise kwigridi.
Umzobo wenkqubo ye-Photovoltaic inverter
Ii-inverters zokugcina amandla zijolise ngakumbi kwizicelo kwiinkqubo zokugcina amandla e-electrochemical, njengezikhululo zamandla okugcina amandla, uhlobo oluphakathi okanye lwentambo, iimeko zoshishino, zorhwebo kunye nekhaya. Kule meko, i-inverters yokugcina amandla ifezekisa ukusetyenziswa ngokufanelekileyo kunye nokugcinwa kwamandla avuselelekayo ngokulawula ngobuchule inkqubo yokutshaja kunye nokukhupha, ukubonelela ngenkxaso yamandla ezinzileyo kunye nethembekileyo kwiimeko ezahlukeneyo zesicelo.

Amanqaku aqhelekileyo kunye neeyantlukwanoNgokubhekiselele kumanqaku aqhelekileyo, zombini izixhobo zombane zombane, ezisetyenziselwa ukuguqulwa kunye nokulawulwa kwamandla ombane ukufezekisa ukusebenza okuzinzile kwenkqubo yamandla. Bonke kufuneka bahlangabezane nemigangatho ethile yokhuseleko lombane ukuqinisekisa ukusebenza ngokukhuselekileyo kwezixhobo. Ukongezelela, ekubeni ii-inverters zokugcina amandla zifuna iinkqubo ezidibeneyo zokulawula ibhetri, iindleko zabo ziphezulu. Umsebenzi we-photovoltaic inverters ulula, ngoko ke ixabiso lihlala liphantsi. Ngexesha elifanayo, ii-inverters zokugcina amandla nazo zineemfuno eziphezulu zokhuseleko. Ukongeza ekuhlangabezaneni nemigangatho esisiseko yokhuseleko lombane, ukhuseleko lwenkqubo yolawulo lwebhetri kunye nemilinganiselo yokukhusela xa kwenzeka ukusilela kwebhetri nako kufuneka kuqwalaselwe.
05 Shwankathela
Ukuqukumbela, kukho ulwahlulo olucacileyo phakathi kwe-photovoltaic inverters kunye ne-inverters yokugcina amandla malunga nemigaqo, iimeko zesicelo, ukuphuma kwamandla, iindleko kunye nokhuseleko. Xa kuziwa kusetyenziso lwehlabathi lokwenyani, kubalulekile ukukhetha izixhobo ezifanelekileyo ngokusekwe kwiimfuno ezithile kunye neemeko. Ukusebenzisana no-AMENSOLAR, njengomvelisi okhokelayo we-solar inverter, uqinisekisa ukufikelela kwizisombululo ezifanelekileyo, ukutsala abasasazi abaninzi ukuba bajoyine inethiwekhi yethu.
