1, Ukuqhathaniswa kwezimiso zokusebenza zezinhlobo ezimbili zamayunithi
1. Umgomo wokusebenza weyunithi yempendulo yamandla
Iyunithi yempendulo yamandla iyidivayisi yokubhuleka esetshenziswa kumasistimu okulawula isivinini esishintshashintshayo, futhi umsebenzi wayo oyinhloko ukunikeza impendulo amandla kagesi avuselelwe akhiqizwe ukuncipha kwemoto kugridi yamandla ngobuchwepheshe bokumodulation be-PWM. Lapho injini isesimweni sokukhiqiza (njengomthwalo wamandla ongase ube khona noma ukwehla okukhulu komthwalo we-inertia), futhi isivinini se-rotor sidlula isivinini esivumelanayo, amandla kagesi akhiqiziwe azogcinwa ku-DC bus filter capacitor yesiguquli sefrikhwensi. Iyunithi yempendulo yamandla ithola ngokuzenzakalelayo i-voltage yebhasi ye-DC, iguqule amandla e-DC kumandla we-AC wefrikhwensi efanayo nesigaba njengegridi, futhi iyixhume kugridi ngemva kwezihlungi zomsindo eziningi. Ukusebenza kahle kwempendulo kungafinyelela ngaphezu kwama-97%.
2. Isimiso sokusebenza seyunithi yokubhuleka
Iyunithi yokubhuleka (iyunithi yokubhuleka edla amandla) idla amandla kagesi avuselelwayo ngesinqanda ukubhuleka sangaphandle. Lapho i-voltage yebhasi ye-DC idlula umkhawulo obekiwe, iyunithi yokubhuleka iyaqhuba ukuze ivumele igagasi ukuthi ligeleze ku-resistor yokubhuleka, iguqule amandla kagesi abe amandla ashisayo ukuze alahle. Lo mklamo ulula futhi unokwethenjelwa, kodwa uchitha amandla ngokuphelele futhi ukhiqize ukushisa okukhulu, okudinga izinyathelo ezengeziwe zokushisa ukushisa.
3, Ukuba nokwenzeka kanye Nezinselele Zobuchwephesha obuhlukile
Ukuhlaziywa Kokwenzeka
Ukuba nokwenzeka kwezomnotho: Izimo zangempela zibonise ukuthi ezimweni zokubhuleka njalo (njengama-elevator nama-centrifuges), isikhathi senkokhelo yotshalo-mali samayunithi wempendulo yamandla ngokuvamile asidluli iminyaka emi-2. Isibonelo, ngemva kokusetshenziswa ibhizinisi elithile lokukhiqiza i-VC, isisetshenziswa esisodwa singonga ugesi ongaphezu kuka-9000kWh ngonyaka.
Ukuba nokwenzeka kobuchwepheshe: Amayunithi empendulo yamandla esimanje azuze ukusebenza okuzenzakalelayo ngokugcwele ngaphandle kwezilungiselelo zepharamitha. Ukufakwa kudinga kuphela ukuxhuma ibhasi le-DC ohlangothini lwegridi, okwenza ukulungisa iphutha kube lula.
Izinkinga ezinkulu zobuchwepheshe
Ukuhambisana kwegridi: Kuyadingeka ukuqinisekisa ukuthi amandla empendulo avunyelaniswa negridi futhi ugweme ukugeleza emuva kwamanje
Ukucindezelwa kwe-Harmonic: I-THD<5% kumele ilawulwe ukuze ihlangabezane nezinga le-IEC61000-3-2
Impendulo enamandla: Idinga ukulandelela ngokushesha izinguquko ku-voltage yebhasi (impendulo yeleveli ye-ms)
Ukuvikelwa kwesistimu: Isidingo sokuthuthukisa izindlela zokuvikela i-overvoltage, overcurrent, kanye nezinga lokushisa elingaphezulu
4. Amacala okusebenza ajwayelekile kanye nezinzuzo
Imboni yezikheshi: Indawo yokuhlala e-Suzhou izuze izinga eliphelele lokonga amandla elingu-30.1% ngemva kokufakwa, ngenkathi yehlisa izinga lokushisa legumbi lomshini ngo-3-5 ℃ futhi yehlisa ukusetshenziswa kwamandla kwesimo somoya ngo-15%.
I-centrifuge Yezemithi: Ngemva kokufaka iyunithi yokubhuleka yemishini engu-22kW ngomshini wokuphendula, inkampani yase-Shenzhen yafushanisa isikhathi sokunciphisa isivinini sisuka kumaminithi angu-10 saya kumaminithi angu-3, yonga u-9000kWh kagesi minyaka yonke futhi yabuyisela utshalomali phakathi neminyaka emibili.
I-Industrial hoist: Ngemva kokulungiswa kwesistimu yokuphakamisa i-shaft ethambekele emayini ethile, izinga lokuvuselela amandla okuvuselela lifinyelele ku-95%, futhi ukukhiqizwa kokushisa kwesistimu kwehliswe ngo-70%.
5. Ezinye Iziphakamiso Zesinqumo
Ezinye izimo ezinconyiwe:
Izimo zokubhuleka njalo (njengama-elevator nama-cranes)
Imishini yenqubo yokusebenzisa amandla aphezulu (njengama-centrifuges, izigayo eziginqikayo)
Imvelo ezwela ukushisa ekamelweni lekhompyutha
Izindawo ezinezindleko zikagesi eziphezulu
Gcina isimo seyunithi yokubhuleka:
Isicelo esilula esinemvamisa yokubhuleka ephansi kakhulu
Amaphrojekthi anotshalomali olulinganiselwe lokuqala
Izindawo ezikude ezinekhwalithi ephansi yegridi yamandla
Indlela yokusebenzisa:
