Kusuka emaphilini okusebenza kwezihospitali, emaphilini okugcina amadatha wokufinyelela kwemali, kanye nemithombo yokuproducwa yokuqhubeka ngokuzenzakalelayo, iziphumo zokungasebenzi kwemithombo yomthombo siyizinkinga efanayo kumalungelo, isafuthi, nokuphila kokusebenza kwezinhlangano zokusebenza. I-Uninterruptible Power Supply (UPS) iyindlela yokugcina, kodwa lokho kuphela uma kuyisifundo esikhulu, futhi lokho kuyaphendulwa ngokuthi kuyikuphi indlela eyodwa: amandla .
Ukukhetha isilinganisi esingasemthwakathini sibangela ukungafaneleko, ukuvulwa kwezinkampani noma ukungasebenzi kusasa lapho kufika umkhawulo wokugcina amandla. Kwa-WTHD, sizobala izinkampani zokusebenza ngamandla okuphepha kanye nokubhekisa izinkinga lezi ngokushesha. Sizobona indlela okuyisho isilinganisi sokuphepha kusindisa ukusebenza kwemithwakathi yokugcina.
Ukulinganisa Ups Isilinganisi Ngezidingo Zokusebenza Zokwesekelwa
Indlela yokuqala nobuncinane yokuqala kukubeka isilinganisi sokuphepha ngokulingana nesilinganisi sokusebenza. Kunezimfano eziningi ezingabonakali ukuthi "kubhili kubhili kubhili". Umphumela wokuba isilinganisi sokuphepha sikhulu kakhulu kubalulekile ukuthi isilinganisi sokuphepha sisebenza ngapansi kwe-30% yomlinganiselo wakho, okubangela ukungafaneleko kakhulu futhi ukuthatha amandla emithwakathi yokuchitha okungadingeki. Ngakolunye uhlangothi, ukubeka isilinganisi sokuphepha ngapansi kakhulu kubangela ukuthi isilinganisi sokuphepha sisebenze ngapakathi kwezinye zokusebenza zakho, okubangela ukuthi kubheke amandla okuchitha okuhambisana nezinye zokusebenza futhi kubangela ukuthi isilinganisi sokuphepha sisebenze ngapansi kakhulu kwezinye zokusebenza, okubangela ukuthi kubheke amandla okuchitha okuhambisana nezinye zokusebenza futhi kubangela ukuthi isilinganisi sokuphepha sisebenze ngapansi kakhulu kwezinye zokusebenza.
Ngaphambi kokukhetha noma yiphi into, i-WTHD ibiza ukuthi kufanele kwenziwe umlando wokulwela okuphelele. Lokhu kubizwa ngokuthi kuzwakalwe amawati (akavunyelwe amavolt-ampere) wezinkampani zonke ezigcwele ekusebenzeni ngeminyaka yokuqhubeka kwempilo. Kusendlini yezinkampani zokusebenza, lezi zinkampani ziyizinkampani zokusebenza, izinkampani zokugcina, izinkampani zokuhlanganisa nezinkampani zokujonga. Kusukela emazinkampani ezinkampani ezihlukaniswe kuze kumazinkampani amakhulu okusebenza emindeni, isikhombisi sakithi se-UPS sinesikhombisa esifana nesikhombisa esifanele ukuthi sibone kahle ukuthi sibuyele kahle futhi sibe nesikhombisa sokuguqula ngokusha. Isikhombisa esihle sokusebenza kuyisikhombisa esiphakathi kwe-40% kanye ne-80% yekhwalifikhesi yayo, ukuthi kubhekwe ukuthi kuyasebenza ngokuphelele nokuthi kuyasebenza ngokuphelele. Lokhu kubhekwe ukuthi iziboni zingaspende kancane kakhulu kwekhwalifikhesi yabo futhi ukuthi bafanele bakwazi ukubhekwa ngokuphelele kwezinhlelo zabo.
Ukuchaza kwe-Factor Yomthelela, Imilayili Yokuphakama Nezidingo Zokuphakama Ngaphezu Kwesikhathi
Ukuplanisha ukhwalifikhesi kuyindlela eyisisekelo. Kunezinto ezintathu ezingenziwe ngokuphakeme okufanele kubhekwa ngokuphakeme : ifaktor yomthelela (PF), imilayili yokuphakama yomthelela kanti ukuphakama ngaphezu kwesikhathi.
Ifakti lephandle kufundwa kakhulu. I-UPS esikwe 100 kVA ekusebenzisa i-power factor ya-0.8 izokhombisa kuphela ama-kW angu-80 amanquma. I-kVA ibonakala ukuthi iyisifano ngokuphelele kumsebenzi uma umsebenzi udinga ama-kW angu-90 kodwa i-UPS izobulawa uma isebenza ngaleso msebenzi. I-efficiency yamadoda asebenzayo kuzo kwe-IT ayiphansi kwe-0.9 kuya kwe-0.95, futhi amandla emithombo yezindawo zokusebenza izodlula ku-0.7. Amasistimu ase-UPS ase-WTHD asinezinkokhelo zokukhombisa i-high PF futhi azinakwenzela ukuthi i-output ibe ne-unity power factor, ngakho-ke uzothola i-wattage enkulu kakhulu kusendaweni yakho.
Amasebenzi okuphakama , njengoko kuyisikhathi sokunquma kwe-air conditioners, i-laser printers, nokuthenga kwezinhlelo zokubona kwemihlaba, kungaba kubili kanye nezintathu kuya kwezintlanu kunezinto zokusebenza zokuphakama. Ukubhekana nesikhathi sokusebenza sokugcina uma usetha i-UPS uzosiza kubulawa kwe-bypass noma/noma ukuvalelwa kwe-battery uma kubeka kwezinye izinto. Sibheka izinkokhelo zokunquma futhi sisho isikhundla sokubeka isikhundla (ngokujwayelekile ngu-125% kuya kwe-150% yomsebenzi wokusebenza) okufanele kubekwe ngokunquma ngaphandle kokuchitha izinto zokugcina.
Ukwenza okusha yilungisele ukuthi yisikhundla sokubhala amaphuzu. I-UPS esiqondile isizwe kancane kakhulu kusukela ekuseni kwezindawo zokugcina idatha nezinkulungwane ezimbili ngonyaka noma indawo yokuproducwa ephatha izihlangu zokusebenza ngokwezinye. Amasistimu we-energi we-WTHD okuqondile nokudibanisa i-UPS okunamandla kuyenza ukuthi amaphuzu asebenzayo ayifakwe ngokushesha ngaphandle kokubuyisela. Lokhu kukhetho lokuthi "ubhale amaphuzu njengoba uyakhula" kuyenza ukuthi ubhale amaphuzu amancane futhi kuyabiza ukuthi ubhale amaphuzu okuhlinzekile okuyakhula ngokufanana nokukhula kwendawo yakho yokusebenza.
Ukubalansisa Ukusebenza Kwesikhundla Sokuhlinzekile, Isikhathi Sokusebenza Nokusebenza Kwesistimu
Izinto ezintathu eziphambili kakhulu zokubalansisa ziyi-: ukusebenza (ukulungisa ivolthi/ifrekhwensi), isikhathi sokusebenza (imizuzwana yokuqiniseka), nokusebenza kwesistimu (izindleko zokusebenza).
Ukusebenza kuyisisekelo sesiqondiso sesiphumo, ngokwesibonelo isine yomlando omhlophe noma kubanzi ukulungiswa kwesivinini (±1%). Ngaphandle kwezinye izithothi zezinkampani zokuphatha i-UPS, izinkampani zokuphatha i-UPS ezinamandla okuhamba ngokugcina amandla e-AC ngokuphathelene ngezinye izimo zemvelo. Lokhu kufikwa ngokuthula kwezimali ngokusebenzisa ukuphatha kwezinhloso zedijithali.
Isikhathi sokusebenza , kunezinhloko yokubonakaliswa phakathi kwezinhloko zokusebenza nezinhloko zokusebenza. Umkhawulo wokusebenza okukhulu uzosetha amandla angaphezulu emabhathirayi, okuyizokuthintela isikhathi sokusebenza kwesikhathi sokusebenza ngamandla amabili okufanana. Umkhawulo omncane uzosebenza ngasikhathi eside kusetyenziswa kwezinhloko zokusebenza, kodwa kungazange kube yisikhundla sokusebenza kakhulu uma izinhloko zokusebenza zingaphezulu. Abakwenzi abasebenza kumakhasini kufuneka baphindele isikhathi sakho sokuphambuka, okuyisikhathi sekhombele 5 iminithi ukusuka kwezinkundla, iminithi eyishumi nesibhili ukugcina ngokuphelele noma amahora amabili ukugcina ukusebenza. Ngokusebenzisa izinhloko zokusebenza ezinokuguqulwa futhi izinhloko zokusebenza zesiLithium-ion, i-WTHD inokunika umkhawulo we-20 kW ngokusebenza kwe-30 kVA futhi izinhloko zokusebenza eziphansi ukusiza isikhathi sokusebenza esifunekayo.
Ukusebenza kwezinhloko , iWTHD yisisekelo sesikhundla sokusebenza kakhulu. Kuma-UPS amahle, i-6%–8% yomthelela wasebenzisa njengekhanda, ngoba isikhundla sokusebenza kuyi-92%–94%. Siyasebenza ngokukhulu kwe-97% kuma-load amahle nge-Eco‑mode yethu kunye nezindlela zokwenza ezingenakho umthwalo wokubeka izithuthi. Kuma-plant ase-100 kW, le-3%–5% yokuthinteka kuyakubiza imali engaphezu kwezinkulungwane zemalayizini yezimalayizini zokusebenza kanye nezimalayizini zokuchitha ukuphakama kwamandla. Ngaphezu kwalokho, izindawo zethu zokuphatha izibhateri ngokushesha zihlola izinkampani zokufaka amandla ngokulingana nomaqhuba okusebenza nokuthi kuyiphi indawo yokuqala yomthwalo, kusondezela ubude bokusebenza kwezibhateri ngo-30% futhi ziyabeka izibhateri ezimiselwe ngokushesha.
Isiphetho
Ukukhulu kwe-UPS akuyiyo kuphela inombolo, kodwa yisibonelo sokuziphatha esihlanganisa izinqumo zezimalayizini zezimalayizini, ifaktor yamandla, ukuthinteka kwezimalayizini, izilungiselelo zokuthuthukisa, izilungiselelo zokusebenza kanye nezilungiselelo zokusebenza kakhulu. I-UPS engeziwe ngokuphelele iyakubeka umsebenzi wokuthengisa waphansi ngokuthi kuyizilungiselelo zokuhlela, ukubuyisela izibhateri noma ukugcina kwakhe ngokuphelele.
Siyisibhakabhaka sezinsiza zokusebenzisa imithombo yamandla, futhi eWTHD, sisebenzisa konke okuthi kuthi kusenziwe ukuthi sibone isikhundla sakho esihlukile, sibonise inkulumo yamandla yokuqala kuwe. Kusukela kubuyiselo lwemithombo yasezweni kuya kuzikhiqizwa zezindawo zokusebenza ngokwesibonelo (OEM/ODM), indlela yethu yokudesigna kuya kumthwalo wokugcina umphathi wakho wokusebenzisa amandla okubuyisela, ukuthi uhlakele, uhlakele, futhi uhlakele inkulumo yakho yamandla okubuyisela, ukuthi ibe yinkulumo efanele futhi iyisibonelo sokuzimela kwesikhathi esizayo. Ekuthengiseni, igama elilungileyo lomsebenzi liyisibonelo sokuthi ubheke phambili, khetha iWTHD futhi usebenzise amandla okuthengisa ngokuphelele.
