Iimpawu zeenkqubo zonikezelo lwamandla zisebenzisa i-Diesel Dynamic Uninterruptible Power Sources (DDIUPS)

Kulo mboniso ulandelayo, umbhali uya kuzama ukuphepha i-clichés yokuthengisa kwaye uya kuxhomekeka ngokukodwa kumava asebenzayo. Ii-DDIBPs ezivela kwi-HITEC Power Protection ziya kuchazwa njengezifundo zovavanyo.

Isixhobo sokufakela i-DDIBP

Isixhobo se-DDIBP, ukusuka kwindawo yokujonga i-electromechanical, sikhangeleka silula kwaye sinokuqikelelwa.
Umthombo oyintloko wamandla yiNjini ye-Diesel (DE), enegunya elaneleyo, ngokuqwalasela ukusebenza kakuhle kofakelo, ukwenzela ixesha elide ukunikezelwa kwamandla okuqhubekayo kumthwalo. Oku, ngokufanelekileyo, kubeka iimfuno ezingqongqo ekuthembekeni kwayo, ukulungela ukuqaliswa kunye nokuzinza komsebenzi. Ke ngoko, kusengqiqweni ngokupheleleyo ukusebenzisa ii-DD zeenqanawa, ezithi umthengisi azipeyintile ukusuka emthubi ukuya kumbala wakhe.

Njengomguquleli oguqulwayo wamandla omatshini kumandla ombane kunye nomva, ukufakela kubandakanya i-motor-generator enamandla angaphezu kwamandla alinganisiweyo ofakelo ukuphucula, okokuqala, iimpawu eziguquguqukayo zomthombo wamandla ngexesha leenkqubo ezidlulayo.

Ekubeni umenzi ubanga unikezelo lwamandla olungenakuphazamiseka, ukufakela kuqulethe into egcina amandla kumthwalo ngexesha lokutshintsha ukusuka kwimodi yokusebenza enye ukuya kwenye. I-accumulator ye-inertial okanye i-induction coupling isebenza kule njongo. Ngumzimba omkhulu ojikelezayo ngesantya esiphezulu kwaye uqokelela amandla omatshini. Umvelisi uchaza isixhobo sakhe njengemoto engatshintshiyo ngaphakathi kwimotor ye-asynchronous. Ezo. Kukho i-stator, i-rotor yangaphandle kunye ne-rotor yangaphakathi. Ngaphezu koko, i-rotor yangaphandle idibaniswe ngokungqongqo kwi-shaft eqhelekileyo yofakelo kwaye ijikeleza ngokuhambelanayo kunye ne-shaft ye-motor-generator. I-rotor yangaphakathi iphinda ijikeleze ngokumalunga neyodwa yangaphandle kwaye ngokwenene sisixhobo sokugcina. Ukubonelela ngamandla kunye nokusebenzisana phakathi kwamalungu ngamanye, iiyunithi zebrashi ezinamakhonkco e-slip zisetyenziswa.

Ukuqinisekisa ukuhanjiswa kwamandla omatshini ukusuka kwimoto ukuya kwiindawo ezisele zofakelo, i-clutch overrunning isetyenziswa.

Inxalenye ebaluleke kakhulu yokufakela yinkqubo yokulawula ngokuzenzekelayo, leyo, ngokuhlalutya iiparitha zokusebenza zamalungu ngamnye, ichaphazela ukulawulwa kofakelo ngokubanzi.
Kwakhona eyona nto ibaluleke kakhulu yofakelo yi-reactor, inqanaba lesithathu lixutywe kunye nempompo ejikelezayo, eyenzelwe ukudibanisa ukufakwa kwinkqubo yonikezelo lwamandla kunye nokuvumela ukutshintshela okukhuselekileyo phakathi kweendlela, ukunciphisa imisinga yokulinganisa.
Kwaye ekugqibeleni, ukuncedisa, kodwa akukho ndlela i-subsystems yesibini - ukungena komoya, ukunikezelwa kwamafutha, ukupholisa kunye nokukhupha igesi.

Iindlela zokusebenza zofakelo lwe-DDIBP

Ndicinga ukuba kuya kuba luncedo ukuchaza iimeko ezahlukeneyo zofakelo lwe-DDIBP:

• imo yokusebenza IVALIWE

Inxalenye yomatshini wofakelo ayishukumi. Amandla anikezelwa kwinkqubo yokulawula, inkqubo yokufudumeza kwangaphambili yemoto, inkqubo yentlawulo edadayo yeebhetri eziqalayo, kunye neyunithi yokungenisa umoya kwakhona. Emva kokufudumala, ukufakela kukulungele ukuqala.

• imo yokusebenza START

Xa umyalelo START unikezelwa, i-DD iqala, ejikeleza i-rotor yangaphandle ye-drive kunye ne-motor-generator ngokusebenzisa i-clutch overrunning. Njengoko i-injini ifudumala, inkqubo yayo yokupholisa iyasebenza. Emva kokufikelela kwisantya sokusebenza, i-rotor yangaphakathi ye-drive iqala ukujikeleza (intlawulo). Inkqubo yokutshaja isixhobo sokugcina igwetywe ngokungathanga ngqo ngoku kusetyenziswayo. Le nkqubo ithatha imizuzu emi-5-7.

Ukuba amandla angaphandle akhoyo, kuthatha ixesha elithile ukulungelelaniswa kokugqibela kunye nenethiwekhi yangaphandle kwaye, xa iqondo elaneleyo lenqanaba liphunyeziwe, ukufakela kuxhunyiwe kuyo.

I-DD inciphisa isantya sokujikeleza kwaye iya kumjikelezo wokupholisa, othatha malunga nemizuzu eyi-10, ilandelwa kukuyeka. I-clutch egqithisiweyo ikhupha kunye nokujikeleza okuqhubekayo kofakelo kuxhaswa yi-motor-generator ngelixa ihlawula ilahleko kwi-accumulator. Ufakelo lulungele ukunika amandla umthwalo kunye nokutshintshela kwimodi ye-UPS.

Ukungabikho kokunikezelwa kwamandla angaphandle, ukufakela kukulungele ukunika amandla umthwalo kunye neemfuno zayo kwi-motor-generator kwaye iyaqhubeka isebenza kwimodi ye-DIESEL.

• indlela yokusebenza DESEL

Kule modi, umthombo wamandla yiDD. I-motor-generator ejikeleziswa yiyo inika amandla umthwalo. I-motor-jeneretha njengomthombo we-voltage ineempendulo ze-frequency echazwe kwaye ine-inertia ephawulekayo, iphendule ngokulibaziseka kwiinguqu zequbuliso kubukhulu bomthwalo. Ngokuba Umenzi ugqiba ukufakwa kunye nokusebenza kwe-DD yolwandle kule modi kunqunyelwe kuphela ngamaziko okugcina amafutha kunye nokukwazi ukugcina iimeko zokushisa zokufakelwa. Kule ndlela yokusebenza, inqanaba loxinzelelo lwesandi kufuphi nokufakela lidlula i-105 dBA.

• Indlela yokusebenza ye-UPS

Kule modi, umthombo wamandla yinethiwekhi yangaphandle. I-motor-generator, exhunywe nge-reactor kwinethiwekhi yangaphandle kunye nomthwalo, isebenza kwimodi ye-synchronous compensator, ihlawulela ngaphakathi kwemida ethile icandelo elisebenzayo lamandla omthwalo. Ngokubanzi, ufakelo lwe-DDIBP oluqhagamshelwe kuthotho kunye nomnatha wangaphandle, ngokwenkcazo, luwohloka iimpawu zalo njengomthombo wombane, onyusa i-impedance yangaphakathi elinganayo. Kule ndlela yokusebenza, inqanaba loxinzelelo lwesandi kufuphi nokufakela malunga ne-100 dBA.

Kwimeko yeengxaki ngenethiwekhi yangaphandle, iyunithi inqanyuliwe kuyo, umyalelo unikezelwa ukuqala injini ye-diesel kwaye iyunithi itshintshela kwimodi ye-DIESEL. Kufuneka kuqatshelwe ukuba ukuqaliswa kwemoto evuthayo rhoqo kwenzeka ngaphandle komthwalo de kube isantya sokujikeleza kwe-motor shaft sidlula iindawo eziseleyo zofakelo kunye nokuvalwa kwe-clutch overrunning. Ixesha eliqhelekileyo lokuqalisa kunye nokufikelela kwisantya sokusebenza seDD yimizuzwana emi-3-5.

• Imo yokusebenza ye-BYPASS

Ukuba kuyimfuneko, umzekelo, ngexesha lokugcinwa, amandla omthwalo angadluliselwa kumgca wokudlula ngokuthe ngqo kwinethiwekhi yangaphandle. Ukutshintshela kumgca we-bypass kunye nomva kwenzeka ngokugqithwa ngexesha lokuphendula kwezixhobo zokutshintsha, okukuvumela ukuba ugweme ukulahlekelwa kwexesha elifutshane kumthwalo ngenxa yokuba. Inkqubo yokulawula izama ukugcina kwinqanaba phakathi kwe-voltage ephumayo yofakelo lwe-DDIBP kunye nenethiwekhi yangaphandle. Kule meko, indlela yokusebenza yofakelo ngokwayo ayitshintshi, i.e. ukuba i-DD yayisebenza, ngoko iya kuqhubeka isebenza, okanye ukufakela ngokwalo kwakunikwe amandla kumnatha wangaphandle, ngoko kuya kuqhubeka.

• indlela yokusebenza YIMA

Xa umyalelo we-STOP unikezelwa, amandla omthwalo atshintshelwa kumgca wokudlula, kwaye ukunikezelwa kwamandla kwi-motor-generator kunye nesixhobo sokugcina siphazamisekile. Ufakelo luyaqhubeka nokujikeleza nge-inertia ixesha elithile kwaye emva kokuyeka ukuya kwimodi ye-OFF.

DDIBP imizobo yoqhagamshelwano kunye neempawu zabo

Ufakelo olulodwa

Olu lolona khetho lulula lokusebenzisa i-DDIBP ezimeleyo. Ufakelo lunokuba neziphumo ezimbini - i-NB (akukho khefu, amandla angenakuphazamiseka) ngaphandle kokuphazamisa ukunikezelwa kwamandla kunye ne-SB (ikhefu elifutshane, amandla aqinisekisiweyo) kunye nokuphazamiseka kwexesha elifutshane lamandla. Isiphumo ngasinye sinokuba ne-bypass yayo (jonga umfanekiso 1.).

Umzobo 1

Ukukhutshwa kwe-NB ngokuqhelekileyo kuxhunywe kumthwalo onzima (i-IT, iipompo zokujikeleza kwefriji, i-air conditioners echanekileyo), kunye ne-SB output ngumthwalo apho ukuphazamiseka kwexesha elifutshane lokunikezelwa kwamandla akubalulekanga (i-refrigeration chillers). Ukuze ugweme ilahleko epheleleyo yonikezelo lwamandla kumthwalo obalulekileyo, ukutshintshwa kwemveliso yofakelo kunye nesekethe ye-bypass yenziwa kunye nexesha elidlulayo, kwaye imisinga yesekethe iyancitshiswa ibe kumaxabiso akhuselekileyo ngenxa yokuchasana okuntsonkothileyo kwenxalenye. Ukujija kwereactor.

Ingqwalasela ngokukodwa kufuneka ihlawulwe kumbane ovela kwi-DDIBP ukuya kumthwalo ongeyena umgca, okt. umthwalo, obonakaliswe kubukho bexabiso elibonakalayo le-harmonics ekubunjweni kwe-spectral yombane osetyenzisiweyo. Ngenxa yezinto ezingaqhelekanga zokusebenza kwejenereyitha ehambelanayo kunye nomzobo woqhagamshelo, oku kukhokelela ekugqwethekeni kwefomati yombane kwimveliso yofakelo, kunye nobukho bezinto ezihambelanayo zangoku ezisetyenzisiweyo xa ufakelo luqhutywa ukusuka. uthungelwano lwamandla ombane olutshintshanayo lwangaphandle.

Ngezantsi imifanekiso yesimo (jonga umfanekiso we-2) kunye nohlalutyo lwe-harmonic lwe-voltage ephumayo (jonga umfanekiso we-3) xa unikwe amandla kwinethiwekhi yangaphandle. I-harmonic i-distortion coefficient idlule i-10% kunye nomthwalo othobekileyo ongeyena umgca ngendlela yokuguqula i-frequency. Ngelo xesha, ukufakela akuzange kutshintshele kwimodi ye-diesel, eqinisekisa ukuba inkqubo yokulawula ayifaki iliso kwiparameter ebalulekileyo njenge-coefficient yokuphazamiseka kwe-harmonic ye-voltage ephumayo. Ngokoqwalaselo, inqanaba lokugqwethwa kwe-harmonic alixhomekanga kumandla omthwalo, kodwa kumlinganiselo wamandla omthwalo ongekho mgca kunye nomgca, kwaye xa uvavanywa kumthwalo ococekileyo osebenzayo, oshushu, imilo yombane ekuphumeni kwesixhobo. ukufakela kusondele ngokwenene kwi-sinusoidal. Kodwa le meko ikude kakhulu kwinyani, ngakumbi xa kufikwa kumandla ezixhobo zobunjineli ezibandakanya abaguquli bamaxesha amaninzi, kunye nemithwalo ye-IT enezinto zombane ezitshintshayo ezingasoloko zixhotyiswe ngolungiso lwamandla (PFC).

Umzobo 3

Kule mizobo kunye nelandelayo, iimeko ezintathu zibalulekile:

• Uxhulumaniso lwe-galvanic phakathi kwegalelo kunye nemveliso yofakelo.
• Ukungalingani komthwalo wesigaba ukusuka kwisiphumo sifikelela kwigalelo.
• Isidingo semilinganiselo eyongezelelweyo yokunciphisa i-harmonics yangoku yomthwalo.
• Amacandelo e-Harmonic yomthwalo wangoku kunye nokuphazamiseka okubangelwa ukuhamba kwee-transients ukusuka kwimveliso ukuya kwigalelo.

Ukujikeleza okufanayo

Ukuze kuphuculwe inkqubo yonikezelo lwamandla, iiyunithi ze-DDIBP zinokudityaniswa ngokuhambelanayo, ukudibanisa igalelo kunye neesekethe eziphumayo zeeyunithi zomntu ngamnye. Kwangaxeshanye, kuyimfuneko ukuqonda ukuba ukufakela kuphulukana nokuzimela kwaye kuba yinxalenye yenkqubo xa iimeko ze-synchronism kunye ne-in-phase zidibene; kwi-physics oku kubhekiselwa kuyo ngegama elinye - ukuhambelana. Ukususela kumbono osebenzayo, oku kuthetha ukuba zonke iifakelo ezibandakanyiweyo kwinkqubo kufuneka zisebenze kwimodi efanayo, oko kukuthi, umzekelo, ukhetho olunomsebenzi olula kwi-DD, kunye nokusebenza okuyingxenye kwinethiwekhi yangaphandle ayamkelekanga. Kule meko, umgca wokudlula udalwe uqhelekileyo kwinkqubo yonke (jonga umfanekiso 4).

Ngesikimu soqhagamshelwano, kukho iindlela ezimbini ezinokuba yingozi:

• Ukudibanisa ukufakwa kwesibini kunye nokulandelayo kwibhasi yokuphuma kwenkqubo ngelixa ugcina iimeko zokuhambelana.
• Ukuqhawula ukufakela okukodwa kwibhasi yokuphuma ngelixa ugcina iimeko zokuhambelana kude kube ukutshintshwa kwemveliso kuvuliwe.

Umzobo 4

Ukuvalwa okungxamisekileyo kofakelo olulodwa kunokukhokelela kwimeko apho iqala ukucotha, kodwa isixhobo sokutshintsha isiphumo asikavulwa. Kule meko, ngexesha elifutshane, umehluko wesigaba phakathi kofakelo kunye nenkqubo yonke inokufikelela kumaxabiso angxamisekileyo, okubangela isiphaluka esifutshane.

Kufuneka kwakhona unikele ingqalelo kumthwalo wokulinganisa phakathi kokufakela komntu ngamnye. Kwizixhobo ezicatshangelwayo apha, ukulinganisa kuqhutyelwa ngenxa yophawu lomthwalo owelayo we-generator. Ngenxa yokunganyaniseki kwayo kunye neempawu ezingafaniyo zeziganeko zofakelo phakathi kofakelo, usasazo alufani. Ukongeza, xa usondela kumaxabiso aphezulu omthwalo, ukuhanjiswa kuqala ukuphenjelelwa zizinto ezibonakala zingabalulekanga njengobude bemigca eqhagamshelweyo, iingongoma zokuqhagamshelana kwinethiwekhi yokusasazwa kofakelo kunye nemithwalo, kunye nomgangatho (ukumelana notshintsho. ) yodibaniso ngokwalo.

Kufuneka sihlale sikhumbula ukuba i-DDIBPs kunye nezixhobo zokutshintsha zizixhobo ze-electromechanical kunye nomzuzu obalulekileyo we-inertia kunye namaxesha okulibaziseka okubonakalayo ekuphenduleni izenzo zokulawula ezivela kwinkqubo yokulawula ngokuzenzekelayo.

Isekethe enxuseneyo kunye noqhagamshelo lwamandla ombane "ophakathi".

Kule meko, i-generator ixhunyiwe kwi-reactor ngokusebenzisa i-transformer kunye nomlinganiselo ofanelekileyo wokuguqulwa. Ngaloo ndlela, i-reactor kunye nokutshintsha oomatshini basebenza kumgangatho we-voltage "umyinge", kwaye i-generator isebenza kwinqanaba le-0.4 kV (jonga umfanekiso 5).

Umzobo 5

Ngalo mbandela wokusetyenziswa, kufuneka ubeke ingqalelo kwimeko yomthwalo wokugqibela kunye nomzobo wokudibanisa. Ezo. ukuba umthwalo wokugqibela uqhagamshelwe nge-step-down transformers, kufuneka kukhunjulwe ukuba ukudibanisa i-transformer kuthungelwano lonikezelo kunokwenzeka kakhulu kukhatshwa yinkqubo yokubuyisela umbane we-core, ethi ibangele ukuqhutyelwa kokusetyenziswa kwangoku kwaye, ngenxa yoko, idiphu yombane (jonga umfanekiso 6).

Izixhobo ezibuthathaka zisenokungasebenzi ngokuchanekileyo kule meko.

Ubuncinci ukukhanya kwe-inertia ephantsi kuyadanyaza kunye neziguquli zemotor frequency frequency ziqalwa kwakhona.

Umzobo 6

Isekethe enebhasi ephumayo "yokwahlula".

Ukuze kwandiswe inani lofakelo kwinkqubo yonikezelo lwamandla, umenzi ucebisa ukusebenzisa iskimu ngebhasi ephumayo "yokwahlula", apho ukufakelwa kuhambelana zombini kwigalelo kunye nemveliso, kunye nofakelo ngalunye oludityaniswe ngaphezulu kwesinye. ibhasi yemveliso. Kule meko, inani lemigca ye-bypass kufuneka lilingane nenani leebhasi eziphumayo (jonga umfanekiso 7).

Kufuneka kuqondwe ukuba iibhasi eziphumayo azizimele kwaye zixhunywe kwi-galvanically omnye komnye ngokusebenzisa izixhobo zokutshintsha zofakelo ngalunye.

Ngaloo ndlela, nangona iziqinisekiso zomenzi, le ngqungquthela imele ukunikezelwa kwamandla omnye kunye nokuphindaphinda kwangaphakathi, kwimeko yesekethe ehambelanayo, eneziphumo ezininzi ezidibeneyo ze-galvanically.

Umzobo 7

Apha, njengakwimeko yangaphambili, kuyimfuneko ukunikela ingqalelo kungekuphela nje ukulinganisa ukulayisha phakathi kofakelo, kodwa phakathi kweebhasi eziphumayo.

Kwakhona, abanye abathengi bachasa ngokuthe ngqo ukunikezelwa kokutya "okungcolileyo", okt. usebenzisa i-bypass kumthwalo kuyo nayiphi na indlela yokusebenza. Ngale ndlela, umzekelo kumaziko edatha, ingxaki (ukulayisha ngaphezulu) kwenye yee-spokes kukhokelela ekuphazamisekeni kwenkqubo kunye nokuvalwa okupheleleyo komthwalo wokuhlawula.

Umjikelo wobomi be-DDIBP kunye neempembelelo zayo kwinkqubo yonikezelo lwamandla xa iyonke

Asimele silibale ukuba ufakelo lwe-DDIBP zizixhobo ze-electromechanical ezifuna ingqalelo, ukutsho oko, isimo sengqondo esinentlonipho kunye nokugcinwa rhoqo.

Ishedyuli yolondolozo ibandakanya ukuphelisa ugunyaziso, ukuvalwa, ukucocwa, ukuthambisa (kanye kwiinyanga ezintandathu), kunye nokulayisha ijenereyitha kumthwalo wovavanyo (kanye ngonyaka). Ngokuqhelekileyo kuthatha iintsuku ezimbini zokusebenza ukwenza inkonzo yofakelo olunye. Kwaye ukungabikho kwesekethe eyenzelwe ngokukodwa ukudibanisa i-generator kumthwalo wokuvavanya kukhokelela kwisidingo sokunciphisa amandla okuhlawula.

Umzekelo, makhe sithathe inkqubo engafunekiyo ye-15 parallel yokusebenza DDIUPS eqhagamshelwe kwi-voltage "yomndilili" kwibhasi "yokwahlula" kabini ngokungabikho kwesekethe ezinikeleyo yokudibanisa umthwalo wovavanyo.

Ngedatha enjalo yokuqala, ukwenza inkonzo ye-30 (!) yeentsuku zekhalenda kuyo yonke enye indlela yosuku, kuya kuba yimfuneko ukukhupha amandla enye yeebhasi zokukhupha ukudibanisa umthwalo wovavanyo. Ngaloo ndlela, ukufumaneka kokunikezelwa kwamandla kumthwalo wokuhlawula enye yeebhasi eziphumayo - 0,959, kwaye ngokwenene kunye ne-0,92.

Ukongeza, ukubuyela kwisekethe yonikezelo lwamandla ombane ohlawulwayo osemgangathweni kuya kufuna ukujika inani elifunekayo leenguqu ezisezantsi, eziya kuthi, zona, zibangele udiphu ombane obuninzi kuyo yonke (!) inkqubo ehambelana nokubuyela umva kwemagneti kweziguquli.

Iingcebiso zokusebenzisa i-DDIBP

Ukusuka apha ngasentla, isiphelo esingathuthuzeliyo sizibonakalisa - ekuphumeni kwenkqubo yokubonelela ngombane usebenzisa i-DDIBP, umgangatho ophezulu (!) I-voltage engaphazamisekiyo ikhona xa zonke ezi meko zilandelayo zidibene:

• Unikezelo lwamandla lwangaphandle alunangxaki ebalulekileyo;
• Umthwalo wenkqubo uhlala uhleli ngokuhamba kwexesha, usebenzayo kunye nomgca wendalo (iimpawu ezimbini zokugqibela azisebenzi kwisixhobo seziko ledatha);
• Akukho ziphazamiso kwinkqubo ebangelwa kukutshintsha izinto ezisebenzayo.

Ukushwankathela, ezi ngcebiso zilandelayo zinokuqulunqwa:

• Ukwahlula iinkqubo zobonelelo lwamandla zobunjineli kunye nezixhobo ze-IT, kwaye zahlule ezi zincinci zibe ziinkqubo ezisezantsi zokunciphisa impembelelo efanayo.
