I-Feedback braking iguqula ugesi ovuselelekayo wemoto ube ugesi we-AC ubuyele kugridi ngefrikhwensi efanayo negridi ngobuchwepheshe obusebenzayo bokubuyisela emuva ukuze kuzuzwe ukutholwa kwamandla. Umongo wayo uthi:
Ukutholwa kwamandla kagesi: kubangela impendulo lapho amandla kagesi ebhasi le-DC edlula izikhathi ezingu-1.2 kunenani elisebenzayo legridi kagesi (njengamasistimu angu-400V afika ku-678V).
Ukulawula okuvumelanayo: Kudingeka ukuthola ngokunembile imvamisa yegridi nesigaba (iphutha elingu-< 1 °) ukuze uqinisekise ukuthi impendulo yamanje ivunyelaniswa negridi.
Umkhawulo Wamanje: Lawula impendulo yamanje ngokushintshashintsha kwe-PWM ukuze ugweme ukungcoliswa kwegridi okubangela ukudlula kwesikhathi (THD <5%).
Ukuhlukaniswa kwezobuchwepheshe kanye nezimo zohlelo lokusebenza
Thayipha Isimo Sohlelo Lokusebenza
I-DC Feedback Reverse Coupling Diode Straightening, Impendulo ku-DC Motherboard DC Motor, Electric Locomotive
I-AC Feedback Full Bridge Inverter + Isihlungi se-LC, Impendulo ku-AC Grid Asynchronous Motor, High Power Frequency Converter
Impendulo exubile ehlanganiswe namadivayisi okugcina amandla (isb. ama-supercapacitor) ukuze kugcinwe ukungasebenzi kahle kwegridi yamandla noma amasistimu angaphandle kwegridi
Izinkomba zokusebenza ezibalulekile
Ukusebenza kahle: impendulo evamile ukusebenza kahle ≥95%, isistimu yamandla aphezulu (> 100kW) ingafinyelela ku-97%.
Isikhathi sokuphendula: Libazisa okungu-<10ms ukusuka ekutholweni kuya ekugawulweni kwe-overvoltage kuya kumpendulo yokuqalisa.
Ukucindezelwa kwe-Harmonic: Hlangana ne-IEC 61000-3-2 ejwayelekile (THD <5%).
Izimo Zokusebenza Ezijwayelekile
Umthwalo omkhulu we-inertial: njengama-centrifuges, izigayo eziginqikayo, amandla avuselelekayo lapho ibhuleki ingafinyelela ku-30% wamandla alinganiselwe enjini.
I-Bit energy load: uma ilifti noma i-crane iwa, amandla adonsela phansi aguqulwa abe amandla kagesi abuyele kugridi.
Ukubhuleka okusheshayo: Isikhathi sokubhuleka sethuluzi lomshini sincishiswa ngaphezu kwama-50%.
Ukukhetha kanye Nokucatshangelwa
Ukuhambisana negridi: Ukushintshashintsha kwamandla kagesi wegridi kufanele kube ≤15%, ngaphandle kwalokho kungase kulimaze idivayisi.
Idizayini yokukhipha ukushisa: Izinga lokushisa lendawo ye-IGBT lidinga u-<125 ℃, ukupholisa komoya okuphoqelekile lapho isivinini somoya ≥2m / s.
Umsebenzi wokuvikela: i-overvoltage / overcurrent protection threshold idinga ukulungiswa (isb. izikhathi ezingu-1.2 zegridi kagesi).
