Umgomo wokonga amandla wamakheshi ukukhulula ugesi olahlwa yimfucuza we-DC onamandla kagesi usuka kusiguquli sefrikhwensi ukuya ku-resistor yokubhuleka ngesikhathi sokusebenza kwekheshi. Ngemva kokutholwa, ukulungiswa, ukuhlanekezelwa, kanye nokuhlungwa yimpahla yokuphendula amandla, yenza impendulo entsha yamandla kagesi evuselelwe futhi ibuyiselwa kugridi yamandla omphakathi yezigaba ezintathu esakhiweni ukuze isetshenziswe. Khona-ke, ugesi ongcolile uphinde usetshenziswe ngokunengqondo ukuze kuzuzwe ukonga amandla nokunciphisa izinga lokushisa legumbi lomshini wekheshi.
Izinzuzo zezomnotho nezemvelo zokufaka imishini yempendulo ye-elevator energy:
Idivayisi yempendulo yamandla inezinga lokuguqulwa elidlula u-97.5% futhi ngeke lingcolise igridi yamandla. Ngokusho kokuhlolwa kwangempela, izinga lokonga amandla lamakheshi e-synchronous lingafinyelela ku-30-48%, kuyilapho ama-asynchronous elevator angafinyelela ku-20-30%. Futhi lapho ijubane liphakeme, amandla amakhulu, umthwalo omkhulu, kanye nomphumela wokonga amandla ongcono. Futhi i-resistor yokuqala yokubhuleka ayisashisi, okwenza izinga lokushisa ekamelweni lomshini lehle, konga izindleko zokuthenga kanye nokusetshenziswa kwamandla kwemishini yokupholisa ekamelweni lomshini.
Ukusetshenziswa kwamandla kwemishini yokupholisa umoya egumbini lekhompyutha kubasebenzisi abajwayelekile cishe ku-4KW. Isebenza izinsuku ezingama-300 ngonyaka ngokwesidingo, ngamahora ayi-12 okusebenza ngosuku, okuholela ekusetshenzisweni kukagesi okuphelele kwe-14400 kWh ngonyaka. Ezindaweni eziningi, izindleko zokuthenga, ukusetshenziswa kukagesi, nokugcina umoya opholile emakamelweni ama-computer kuphela kuyizindleko ezinkulu. Futhi amakheshi emphakathini awaphehli ugesi wonke ngesikhathi esisodwa. Amanye amakheshi aphehla ugesi kuyilapho amanye ewusebenzisa phezulu. Isamba semitha kagesi yendawo ikala ukusetshenziswa kukagesi wegridi yamandla kagesi yangaphandle, okuzonciphisa isamba sesilinganiso semitha futhi ngendlela efanayo yehlise inkokhelo yenkampani kagesi.
2. Amakheshi asephenduke ugesi wesibili ngobukhulu emphakathini wanamuhla, okwesibili ngemuva kwe-air conditioning, ehlanganisa cishe u-20% -30% wokusetshenziswa kukagesi womphakathi. Ekupheleni konyaka wezi-2016, inani lamakheshi e-China lidlule izigidi ezi-4.5, okulenza libe yindawo yamandla ekhemisi yomhlaba wonke enesabelo semakethe esingu-60% emhlabeni jikelele. Ukongiwa kwamandla ekheshi sekube yisigaba esibalulekile sokongiwa kwamandla omphakathi eShayina. Ikheshi elijwayelekile lidla cishe u-30-80 kWh kagesi ngosuku. Ngokusekelwe ekusetshenzisweni kwamandla kwansuku zonke kwama-50 kWh ilifti ngayinye kanye nokusebenza konyaka kwezinsuku ezingama-300, namayunithi ayizigidi ezi-4 asetshenziswa ezweni lonke, ukusetshenziswa kukagesi nsuku zonke kwamakheshi yizigidi ezingama-200 kWh, okungama-kWh ayizigidi eziyizinkulungwane ezingama-60 ngonyaka! Ukusetshenziswa kukagesi kudlula izingxenye ezimbili kwezintathu zokukhiqiza amandla onyaka weMigobho Emithathu, okubonisa ukusetshenziswa kwamandla okukhulu kwamakheshi! Ngakho-ke, kudingekile kakhulu ukulondoloza amandla kuma-elevator ekusebenzeni.
Umthelela wezisetshenziswa zempendulo yamandla kumakheshi:
1. Ngeke kuthinte ukusebenza okuvamile kwekheshi nhlobo.
Idivayisi yempendulo yamandla ngeke iguqule noma yimaphi amasekhethi noma izintambo zesistimu yokulawula yekheshi. Vele uxhume isiphetho sokufaka ngokuhambisana nebhasi le-DC elinevoltage ephezulu yokukhipha isiguquli se-lifti, bese uxhuma isiphetho esiphumayo ngokuhambisana nesishintshi samandla esingu-380V.
Idivayisi yempendulo yamandla ibamba futhi ibuyisele ugesi wemfucumfucu we-DC onevoltage ephezulu okhishwe isiguquli sefrikhwensi ukuya kusiphikisayo sokubhuleka esinamandla amakhulu phakathi nokusebenza kwekheshi. Ngemva kokulungiswa, ukuguqulwa, nokuhlunga, kwakha impendulo entsha yamandla kagesi avuselelwe futhi isetshenziselwa ukulungisa igridi yamandla omphakathi enezigaba ezintathu esakhiweni. Lokhu kufeza umphumela wokonga amandla wekheshi futhi ngeke kuthinte ukusebenza kwayo okuvamile.
Imishini yokunikeza impendulo yamandla iye yahlelwa kahle kakhulu ngokuya nge-software nehadiwe ukuze kugcinwe ikheshi. Okokufaka okugcwele kokulungiswa kwebhuloho kukhethwa embobeni yokufaka ukuze kuqinisekiswe ukusebenza okuvamile ngisho nalapho ugesi we-DC uhlehliswa. Ukunikezwa kwamandla kwezigaba ezintathu okubuyiselwe kugridi akudingi ukwazi ukulandelana kwesigaba, futhi isofthiwe izobona ngokuzenzakalelayo ukulandelana kwesigaba ngesikhathi sangempela futhi ikulungise ngobuhlakani. Ngakho-ke, mayelana ne-wiring, iqeda ngokuphelele amathuba okusebenza okungavamile kwemishini noma ukusebenza kwe-elevator okubangelwa izintambo ezingaxhunywanga. Futhi ukuphepha kwe-fuse esheshayo kuxhunywe ngokuhlukene ochungechungeni lwezintambo ezixhuma ukuphuma kwe-DC kanye nempendulo yegridi yamandla yezigaba ezintathu zekheshi. Uma kwenzeka okungavamile, ukuphepha kwe-fuse esheshayo kuzonqamula ngokushesha okokusebenza kwempendulo kukheshi, kuqinisekise ukuphepha kwekheshi kanye nempahla yokuphendula.
2. Ingabe ijeneretha izoba nomthelela emshinini wempendulo yamandla ngemva kokunqamuka kukagesi
Awukho umthelela. Ngemva kokucima kukagesi kukheshi, idivayisi yempendulo yamandla izokhomba ngobuhlakani ukuphela kwegridi yamandla futhi imise okukhiphayo ngokushesha. Lapho i-generator ikhiqiza ugesi, ingakwazi ukuhlukanisa imvamisa kanye nesigaba sokunikezwa kwamandla kwemishini yokuphehla amandla, ukunciphisa umthwalo nokukhiqizwa kokushisa kwe-generator, engaphumeleli nje kuphela umphumela wokonga amandla kodwa futhi yandisa impilo yesevisi ye-generator.
3. Ingabe kuzoba khona noma yimuphi umthelela ekutakuleni abantu abavaleleke kanye nokuslayida isilayidi mathupha
Awukho umthelela. Lapho uhlenga umuntu ovaleleke ku-elevator, kuyadingeka ukunqamula amandla. Ngalesi sikhathi, kokubili okokusebenza kanye nekheshi akunawo ugesi futhi kusesimweni esimisiwe. Noma ngabe i-voltage yebhasi ye-DC ikhuphuka, okokusebenza ngeke kusebenze.
4. Ingabe ithinta indawo yokusebenza yekheshi
Inomthelela, ikhwalithi ephezulu!
Idivayisi yempendulo yamandla ithola ngobuhlakani futhi iguqule ugesi olahliwe phakathi nokusebenza kwekheshi ube amandla kagesi amasha ukuze kwakhiwe igridi yamandla ukuze iphinde isetshenziswe. I-resistor ye-braking inciphisa ukushisa, futhi izinga lokushisa layo yonke iKhabhinethi yokulawula ijwayele ukushisa kwekamelo, kunciphisa kakhulu izinga lokushisa lokusebenza kwe-converter frequency, ithuthukise kakhulu indawo yokusebenza yesistimu yokulawula i-elevator, nokwandisa impilo yesevisi yesistimu yokulawula kanye ne-elevator. Igumbi lekhompiyutha alisasebenzisi isimo somoya nezinye izinto zokupholisa, ezingasindisa ukusetshenziswa kwamandla kwemishini yokupholisa umoya neyokupholisa ekamelweni lekhompyutha, yonge amandla nokuvikelwa kwemvelo, futhi yenze lonke uhlelo luwonge kakhudlwana ugesi.
