3.Ukutshintsha isimo
Xa umguquli unikwe amandla ukuya kwi-shutdown yokuqala, inkqubo yokulawula iya kugqiba ukuzijonga ukuze kuqinisekiswe ukunyaniseka kolawulo kunye neenkqubo zenzwa.Isikrini sokuchukumisa kunye ne-DSP ziqala ngokuqhelekileyo kwaye umguquleli ungena kwimeko yokuvala.Ngexesha lokuvala, umguquleli wokugcina amandla uvimba iipulses ze-IGBT kwaye unqamule abafowunelwa be-AC / DC.Xa ukwimo yokulinda, isiguquli sogcino lwamandla sivala iipulses ze-IGBT kodwa sivale ii-AC/DC zoqhagamshelwano kunye nesiguquli sikwimo yokulinda eshushu.
● Cima
Isiguquli sogcino lwamandla sikwimowudi yokuvala xa kungekho miyalelo yokusebenza okanye ucwangciso lufunyenweyo.
Kwimodi yokuvala, umguquleli ufumana umyalelo wokusebenza kwisikrini sokuchukumisa okanye kwikhompyutheni ephezulu kwaye idluliselwe kwimodi yokuvala ukuya kwimodi yokusebenza xa iimeko zokusebenza zidibene.Kwimo yokusebenza, isiguquli sisuka kwimowudi yokusebenza siye kwimowudi yokuvala ukuba kufunyenwe umyalelo wokuvala.
● Ukulinda
Kwimo yokulinda okanye yokusebenza, isiguquli sifumana umyalelo wokulinda ovela kwiscreen sokucofa okanye kwikhompyuter ephezulu kwaye singena kwimowudi yokulinda.Kwimowudi yokulinda, umnxibelelanisi we-AC kunye ne-DC we-converter uhlala uvaliwe, umguquleli ungena kwimodi yokusebenza ukuba umyalelo wokusebenza okanye ukucwangciswa kufunyenwe.
● Ukubaleka
Iindlela zokusebenza zinokwahlulwa zibe ziindlela zokusebenza ezimbini: (1) imowudi yokusebenza ngaphandle kwegridi kunye (2) nemowudi yokusebenza eqhagamshelwe kwigridi.Imowudi eqhagamshelwe kwigridi ingasetyenziselwa ukwenza ukutshaja kunye nokukhupha.Kwimowudi eqhagamshelwe kwigridi, umguquli unakho ukwenza ummiselo womgangatho wamandla kunye nolawulo lwamandla olusebenzayo.Kwimowudi ye-off-grid, umguquli unokubonelela nge-voltage ezinzileyo kunye nokukhutshwa kwe-frequency kumthwalo.
● Impazamo
Xa umatshini ungasebenzi kakuhle okanye iimeko zangaphandle azikho kumatshini ovumelekileyo wokusebenza, umguquleli uya kuyeka ukusebenza;qhawula abafowunelwa be-AC kunye ne-DC ngokukhawuleza ukwenzela ukuba isiphaluka esiyintloko somatshini sinqanyulwe kwibhetri, igridi okanye umthwalo, apho ingena kwimeko ephosakeleyo.Umatshini ungena kwimeko ephosakeleyo xa amandla esusiwe kwaye impazamo isusiwe.
3.Imo yokusebenza
Iindlela zokusebenza zesiguquli zinokwahlulwa zibe ziindlela ezimbini zokusebenza: (1) imowudi yokusebenza ngaphandle kwegridi kunye (2) nemowudi yokusebenza eqhagamshelwe kwigridi.
• Imowudi eqhagamshelwe kwigridi
Kwimowudi edityanisiweyo yegridi, umguquli unokwenza imisebenzi yokutshaja kunye nokukhupha.
Ukutshaja kubandakanya ukutshaja ngokuqhubekayo (DC), ukutshaja kombane rhoqo (DC), ukutshaja umbane rhoqo (DC), ukutshaja umbane rhoqo (AC), njl.

• Imowudi engekho kwigridi
Kwimowudi ye-off-grid, iibhetri zikhutshwa ukuze zinikeze i-voltage eqhubekayo kunye ne-frequency AC unikezelo lwamandla olulinganiswe kwi-250kVA kumthwalo.Kwiinkqubo ze-microgrid, iibhetri zinokuhlawuliswa ukuba umbane owenziwe ngujeneretha wangaphandle mkhulu kumandla asetyenziswe ngumthwalo.
• Ukutshintsha imo
Kwimowudi edibeneyo yegridi, ukutshintshwa phakathi kokutshaja kunye nokukhutshwa kwesiguquli sokugcina amandla kunokuqhutywa ngokuthe ngqo, ngaphandle kwesidingo sokungena kwimeko yokulinda.
Ukutshintsha phakathi kokutshaja kunye nokukhupha imowudi kunye nemodi ye-inverter ezimeleyo ayinakwenzeka phambi kwegridi.Qaphela: Ngaphandle kwemowudi yokutshintsha engenamthungo.
Akufuneki kubekho ubukho begridi ukuze i-inverter ezimeleyo isebenze.Qaphela: Ngaphandle kokusebenza okufanayo.
4.Umsebenzi wokukhusela osisiseko
Umguquli okrelekrele unomsebenzi wokukhusela ophucukileyo, xa i-voltage yegalelo okanye ngaphandle kwegridi isenzeka, inokusebenza ngokufanelekileyo ukukhusela ukusebenza okukhuselekileyo komguquli okrelekrele kude kube kusonjululwe ngaphandle kwaye emva koko uqhubeke nokuvelisa umbane.Izinto zokukhusela zibandakanya.
