Emkhakheni wamandla amasha, ama-inverters e-photovoltaic kanye nama-inverters okugcina amandla ayimishini ebalulekile, futhi adlala indima ebalulekile ekuphileni kwethu. Kodwa uyini ngempela umehluko phakathi kwalokhu okubili? Sizokwenza ukuhlaziya okujulile kwalawa ma-inverters amabili kusuka ezicini zesakhiwo, umsebenzi, izimo zohlelo lokusebenza, njll.
01 Umehluko wesakhiwo
Okokuqala, empeleni, i-inverter iyithuluzi eliguqula amandla e-DC abe amandla e-AC. Isebenzisa izici zokushintsha zamadivayisi we-semiconductor (njengama-transistors womphumela wenkundla noma ama-thyristors, njll.) ukulawula amandla kagesi kanye namanje ngokushintsha okusheshayo, ngaleyo ndlela kuzuzwe ukuguqulwa kusuka ku-DC kuya ku-AC.
Umdwebo we-Photovoltaic inverter topology
I-inverter yokugcina amandla (i-PCS) ingumqondo obanzi, obandakanya ukuguqulwa nokulawulwa kwamandla kagesi ngamadivaysi kagesi kagesi ukuze kuzuzwe ukudluliswa kwamandla, ukuguqulwa nokulawula. I-PCS ikakhulukazi ihlanganisa i-rectifier, inverter, ukuguqulwa kwe-DC/DC nezinye izingxenye zemojula, lapho imojula yokuguqula iyingxenye eyodwa kuphela yezingxenye zayo.

02 Izici
Ngokusebenza, isiguquli se-photovoltaic sigxile kakhulu ekuguquleni amandla e-DC akhiqizwe amaphaneli e-solar photovoltaic abe amandla e-AC ukuze asetshenziswe kugridi yamandla noma izinto zikagesi. Ithuthukisa amandla okukhiphayo we-solar photovoltaic array ngokusebenzisa amasekhethi angaphakathi namamojula okulawula, yenza uchungechunge lwezinqubo kumandla e-DC akhiqizwe amaphaneli e-photovoltaic, futhi ekugcineni ikhiphe amandla e-AC ahlangabezana nezimfuneko zegridi yamandla.
Ama-inverters okugcina amandla anaka kakhulu ukuguqulwa kwezindlela ezimbili kanye nokuphathwa okuhlakaniphile kwamandla kagesi. Ayiguquli kuphela amandla e-DC abe amandla e-AC, kodwa futhi iguqula amandla e-AC abe amandla e-DC ukuze agcinwe. Ngaphezu kokuqaphela ukuguqulwa kwe-DC kuya ku-AC, iphinde isekele ukuxhumana kwe-BMS/EMS, ukuphathwa kwezinga le-cluster, ukushaja okukhushuliwe kanye nomthamo wokukhipha, ukuphathwa okuzimele kwendawo yokushefa okuphezulu nokugcwaliswa kwesigodi, kanye nokuhlela okuhlakaniphile kokushaja kanye nokukhipha amandla okugcinwa kwamandla. uhlelo.
03 Izimo zohlelo lokusebenza
Ngokwezimo zohlelo lokusebenza, ama-photovoltaic inverters asetshenziswa ikakhulukazi ezinhlelweni zokuphehla amandla elanga, njengezinhlelo ze-photovoltaic zasendlini, amaphrojekthi we-photovoltaic ezimbonini nezohwebo, kanye neziteshi ezinkulu zamandla aphansi. Umsebenzi wayo oyinhloko ukuguqula amandla e-DC wesistimu yokuphehla amandla elanga abe amandla e-AC futhi awahlanganise kugridi.
Umdwebo wesistimu ye-Photovoltaic inverter
Ama-inverter okugcina amandla agxile kakhulu ezinhlelweni zokugcina amandla kagesi kagesi, njengeziteshi zamandla okugcina amandla, uhlobo oluphakathi nendawo noma lwezintambo, izimo zezimboni, ezentengiselwano nezasekhaya. Kulezi zimo, ama-inverters okugcina amandla afinyelela ukusetshenziswa okuphumelelayo nokugcinwa kwamandla avuselelekayo ngokuphatha ngobuhlakani inqubo yokushaja nokukhipha, ehlinzeka ngokusekelwa kwamandla okuzinzile nokuthembekile ezimeni ezihlukahlukene zohlelo lokusebenza.
04 Umdwebo wesistimu ye-inverter yokugcina amandla
Amaphuzu avamile kanye nokwehlukaNgokuqondene namaphuzu avamile, kokubili kungamadivayisi kagesi kagesi, asetshenziselwa ukuguqulwa nokulawulwa kwamandla kagesi ukuze kuzuzwe ukusebenza okuzinzile kwesistimu yamandla. Bonke badinga ukuhlangabezana nezindinganiso ezithile zokuphepha zikagesi ukuze kuqinisekiswe ukusebenza okuphephile kwemishini. Ngaphezu kwalokho, njengoba ama-inverters okugcina amandla adinga izinhlelo ezididiyelwe zokuphatha ibhethri, izindleko zabo ziphakeme kakhulu. Umsebenzi wama-inverters we-photovoltaic ulula, ngakho-ke izindleko ngokuvamile ziphansi. Ngesikhathi esifanayo, ama-inverters okugcina amandla nawo anezidingo eziphakeme zokuphepha. Ukwengeza ekuhlangabezaneni nezindinganiso eziyisisekelo zokuphepha zikagesi, ukuphepha kwesistimu yokuphatha ibhethri nezinyathelo zokuvikela uma kwenzeka ibhethri lihluleka nakho kufanele kucatshangelwe.
05 Fingqa
Sengiphetha, kunomehluko osobala phakathi kwama-inverters e-photovoltaic nama-inverters okugcina amandla ngokuphathelene nezimiso, izimo zohlelo lokusebenza, ukuphuma kwamandla, izindleko, nokuphepha. Uma kukhulunywa ngezinhlelo zokusebenza zomhlaba wangempela, kubalulekile ukukhetha okokusebenza okufanele ngokusekelwe ezidingweni ezithile nezimo. Ukubambisana ne-AMENSOLAR, njengomkhiqizi oholayo we-solar inverter, kuqinisekisa ukufinyelela ezisombululweni ezifanele, ukuheha abasabalalisi abaningi ukujoyina inethiwekhi yethu.
