Umphakeli wemishini esekela i-frequency converter ukukhumbuza ukuthi ekukhiqizweni kwezimboni, kucatshangelwa ubunjalo bezimo zokusebenza, uma kwenzeka iphutha elithile ohlelweni, okubangela ukuthi umthwalo wamandla ongase ube khona othwalwa yinjini ukusheshisa ngokukhululeka nokuwa, injini izoba sesimweni sokusebenza sokukhiqiza amandla. Amandla akhiqizwe kabusha azobuyiselwa kusekethe ye-DC ngama-diode ayisithupha ahamba ngamasondo, okubangele ukwanda ku-∆ d nokubeka ngokushesha isiguquli sefrikhwensi esimweni sokushaja. Ngalesi sikhathi, umsinga uzoba phezulu kakhulu. Ngakho-ke i-diameter ye-reactor ekhethiwe kufanele ibe nkulu ngokwanele ukudlula okwamanje ngalesi sikhathi.
I-Dynamic Braking Unit isetshenziswa kakhulu ezimeni lapho isiguquli sefrikhwensi sidinga ukwehla ngokushesha, ukuma, kanye nokubhuleka. Uma isiguquli sefrikhwensi sibhuleka, ngenxa ye-inertia enkulu yomthwalo, sizoguqula amandla e-kinetic abe amandla kagesi, okubangele ukuthi i-voltage yebhasi ye-DC yesiguquli sefrikhwensi inyuke. Ukuze ungathinti ukusebenza okujwayelekile kwesiguquli semvamisa, kuyadingeka ukusebenzisa iyunithi yokubhuleka ukuze kudle amandla kagesi avuselelwe, ngaphandle kwalokho isiguquli semvamisa sizokweqa ukuvikelwa kwe-voltage futhi sithinte ukusebenza kwayo okuvamile.
Umsebenzi wedivayisi yempendulo yamandla ukubuyisela ngempumelelo amandla kagesi avuselelwe enjini kugridi yamandla e-AC ukuze isetshenziswe ezinye izisetshenziswa zikagesi ezizungezile. Umphumela wokonga amandla usobala kakhulu, futhi izinga elijwayelekile lokonga amandla lingafinyelela ku-20% kuya ku-50%. Ngaphezu kwalokho, ngenxa yokungabikho kwezakhi zokushisa eziphikisanayo, izinga lokushisa ekamelweni lekhompyutha liyehla, elingasindisa ukusetshenziswa kwamandla kwe-air conditioning ekamelweni lekhompyutha. Ezimweni eziningi, ukonga ukusetshenziswa kwamandla kwesimo somoya ngokuvamile kuholela emiphumeleni engcono yokonga amandla.
Ukuze usebenzise isistimu yokulawula isivinini esishintshashintshayo esimweni sempendulo yamandla, lezi zimo ezilandelayo kufanele kuhlangatshezwane nazo:
(1) Uhlangothi lwegridi ludinga ukusetshenziswa kwama-inverter alawulekayo. Lapho i-motor isebenza esimweni sempendulo yamandla, ukuze kuzuzwe impendulo yamandla kugridi, i-inverter ye-grid side kufanele isebenze ku-inversion state, futhi ama-inverters angalawuleki awakwazi ukuzuza ukuguqulwa.
(2) I-voltage yebhasi ye-DC kufanele ibe phezulu kunomkhawulo wempendulo. Isiguquli sefrikhwensi sidinga ukuphendula amandla kugridi, futhi inani levolthemu yebhasi le-DC kufanele libe phezulu kunomkhawulo wempendulo ukuze kukhishwe okwamanje kugridi. Ngokuqondene nokulungiselelwa kombundu, kuya nge-voltage yegridi nokusebenza kokumelana nomthamo we-converter frequency.
(3) I-voltage yempendulo kufanele ifane nefrikhwensi yegridi kagesi. Phakathi nenqubo yempendulo, kuyadingeka ukulawula ngokuqinile imvamisa ye-voltage ephumayo ukuze ifane nefrikhwensi ye-voltage yegridi ukuze kugwenywe umthelela wokwanda.
Ukuguqula amandla okusebenza (amandla okungenzeka, amandla e-kinetic) emthwalweni ngesikhathi sokunyakaza abe amandla kagesi (amandla kagesi avuselelwe) ngokusebenzisa idivayisi yempendulo yamandla futhi iwabuyisela kugridi yamandla kagesi ye-AC ukuze isetshenziswe ezinye izisetshenziswa zikagesi eziseduze, ukuze uhlelo lokushayela imoto lukwazi ukunciphisa ukusetshenziswa kwamandla kagesi wegridi ngesikhathi seyunithi, ngaleyo ndlela kufinyelele umgomo wokonga amandla.
