Uhlolojikelele lwamayunithi empendulo yamandla
Iyunithi yempendulo yamandla isho idivaysi esetshenziswa kusistimu yokuguqula imvamisa ukuze ibone ukukhiqizwa kwamandla nokuxhumeka kwegridi. Lapho injini isebenza, ngenxa yokuba khona kwe-motor inertia, ngesikhathi lapho amandla ashukumisayo e-motor ezonyamalala, iyunithi yempendulo yamandla ingabuyisela amandla akhiqizwe injini kugridi, ngaleyo ndlela izuze ukubuyiswa kwamandla kanye nokusetshenziswa.
I-Energy Feedback Unit Working Principle
Umgomo wokusebenza kweyunithi yempendulo yamandla usekelwe ku-inertia yokunyakaza kwemoto. Lapho injini isebenza, injini ikhiqiza inani elithile lamandla anamandla kanye ne-kinetic ngenxa yesenzo se-inertia. La mandla adinga ukuchithwa ngaphambi kokuba injini iyeke ukuhamba, kodwa uma la mandla engase atholakale futhi afakwe kugridi, angafinyelelwa ukuze alulame futhi asebenzise amandla kabusha.
Umnyombo weyunithi yempendulo yamandla ukuguqula imvamisa. Lapho injini isebenza, isistimu yokulawula isiguquli sefrikhwensi ingakwazi ukuzwa ngokushesha isimo sokunyakaza kwemoto. Uma i-motor isekupheleni kokunyakaza, amandla angenayo akhiqizwa makhulu, isiguquli semvamisa sizobuyisela ngokuzenzakalelayo ugesi kugridi. Indlela yempendulo ikakhulukazi ihlanganisa: ibhodi lokutholwa kwe-motor-signal-inverter-frequency converter-grid.
Ukusetshenziswa kwe-Energy Feedback Units
Amayunithi empendulo yamandla asetshenziswa kakhulu, ikakhulukazi emikhakheni efana nokuphehla amandla egesi kanye nokuphehla amandla omoya. Ngenxa yokuguquguquka okukhulu kwesivinini sokujikeleza kweyunithi yokuphehla amandla lapho ikhiqiza amandla, amandla amakhulu angenayo abuya kancane azokhiqizwa lapho injini iyeka ukusebenza. Amayunithi empendulo yamandla angasetshenziswa ukubuyisela lawa mandla, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokusetshenziswa kwamandla kwesistimu.
Isifinyezo
Iyunithi yempendulo yamandla iyingxenye ebaluleke kakhulu yesistimu yokuguqula imvamisa. Isebenzisa izici zamandla angenawo ukunyakaza kwemoto ukuze kuzuzwe ukutholwa kwamandla nokusetshenziswa kabusha. Njengoba amandla ancipha kancane kancane, ukusebenza kahle kokusetshenziswa kwamandla kuya ngokuya kubaluleka, futhi amathemba okusetshenziswa kweyunithi yempendulo yamandla azokwanda kakhulu.
