Izimiso zobuchwepheshe kanye nezinzuzo ezibalulekile
Ubuchwepheshe be-Feedback braking buvumela ukusetshenziswa ngendlela eyonga ugesi ngokubuyisela ugesi okhiqizwa isimo senjini sokukhiqiza amandla kabusha kugridi noma idivayisi yokugcina amandla. Izinzuzo zayo eziyinhloko zihlanganisa:
Ukonga amandla: Uma kuqhathaniswa nokubhuleka okudla amandla (ugesi uguqulwa ube yimfucuza yokushisa), ibhuleki lempendulo lingabuyisa u-15% -30% wamandla okubhuleka.
Ukuvikelwa kwesistimu: ukugwema ukulimala kwamandla kagesi webhasi le-DC ngenxa yokunqwabelana kwamandla avuselelekayo, kunwebe impilo yezinto zokusebenza.
Ukusabela okunamandla: kulawulwa ngokuhambisana nesiguquli sefrikhwensi ukuze kubhuleki ngokushesha (isb. izinhlelo zokusebenza zewintshi ezimayini zinganciphisa ukuguga kwesango).
Okwesibili, isimo samanje sezicelo zemboni
Imboni:
Ama-frequency converter asetshenziswa kakhulu kumadrayivu emoto asynchronous, kanti ngo-2025 usayizi wemakethe yokuguqula imvamisa yaseChina kulindeleke ukuthi udlule ama-yuan ayizigidi eziyizinkulungwane ezingama-60, kanti iziguquli ze-high-voltage frequency zibalwa ku-35%.
Emakheni amamayini, amaphampu enjini yomoya kanye nezinye izimo zomthwalo, ukubhuleka impendulo kunganciphisa izindleko zokulungisa ngaphezulu kwama-40%.
Izimoto zamandla amasha:
Izimoto zikagesi zithuthukisa amakhilomitha ngokubhuleka impendulo, ukuvuthwa kwezobuchwepheshe kuphezulu, kodwa kuyadingeka ukuxazulula inkinga yokuphazanyiswa kwe-harmonic yegridi.
Izitayela zesikhathi esizayo
Ukuhlanganiswa Kwezobuchwepheshe:
Ihlanganiswe nama-algorithms ahlakaniphile, ifinyelela ukwabiwa kwetorque yokubhuleka okunembayo (njengokusebenza kahle kwesilawuli segiya kazibuthe esingafika ku-98%).
Isidingo sama-high-voltage frequency converters ezimbonini zamandla ne-metallurgy siyakhula, futhi usayizi wemakethe ungase udabule ama-yuan ayizigidi eziyizinkulungwane eziyi-16 ngo-2025.
Iqhutshwa Inqubomgomo:
I-Motor Energy Efficiency Improvement Plan yase-China idinga ukuthi izinjini ezonga ugesi zibe ngaphezu kwama-70% ngo-2025 ukuze kuthuthukiswe ukuthandwa kobuchwepheshe be-feedback braking.
Izimakethe Ezisafufusa:
Isifunda sase-Asia-Pacific (ikakhulukazi i-China) sizoba injini yokukhula, kanti imakethe yezimoto zokuguqula imvamisa kulindeleke ukuthi ifinyelele kuma-yuan ayizigidi eziyizinkulungwane eziyi-150 ngo-2025.
Izinselele kanye nentuthuko
Ukusebenzisana kwegridi: Amasu okulawula isiguquli kudingeka athuthukiswe ukuze kuncishiswe umthelela wezimpendulo kugridi.
Ukulawulwa kwezindleko: Izinga lasekhaya lama-inverter anamandla amakhulu likhuphuke lafinyelela ku-58%, kodwa imakethe esezingeni eliphezulu isabuswa ama-giants international afana ne-Siemens.
