Macluumaadka aasaasiga ah ee isticmaalayaasha
Shirkada balaastigga ah ayaa inta badan soo saarta tuubooyinka biyaha PE, birta birta ah ee tuubooyinka dareeraha, iwm. Shirkaddu waxay leedahay 4 khadadka wax soo saarka, qayb ka mid ah xoogga wadista waxay isticmaashaa matoorrada cadayga ah ee DC iyo matoorada isdabajoogga ee DC, waxaa jira afar qaybood oo 400KVA ah, mid kasta oo Transformer ah. dhinaca cadaadiska hoose oo lagu qalabeeyay sanduuqa magdhowga awooda.Jaantuska nidaamka sahayda korontadu waa sida soo socota:
Xogta hawlgalka dhabta ah
Matoorka DC ee 400KVA Transformer, awoodda sare ee beddelka waa 360KW, celceliska awoodda awoodda waa PF = 0.7, hadda shaqeyntu waa 780A, sanduuqa magdhowga aan ansax ahayn ee ka hooseeya transformer kasta ayaa badanaa safra, capacitor-ku wuu fidiyaa oo dillaacaa, Xakameeyaha ma xakameyn karo cilladaha aan caadiga ahayn, iwm. Dhacdooyinka, heerka guud waa 0.8 kaliya, ganaaxa aan ansaxeyn waa qiyaastii 15,000 bishii.Intaa waxaa dheer, matoorada iyo bilawga jilicsan ee khadka wax soo saarka ayaa mararka qaarkood waxyeello u geysta, taas oo saameynaysa wax soo saarka.
Falanqaynta Xaaladda Nidaamka Awoodda
Culayska ugu weyn ee matoor aan burushka lahayn ee DC iyo sahayda korontad beddelka waa 6 koronto toosiye hal-pulse ah.Inta lagu jiro hawlgalka qalabka toosiyaha, AC waxa loo rogi karaa DC, samaynta tiro badan oo ah ilo hadda garaaca wadnaha, soo bandhigida qulqulka iswaafajinta ee shabagga korantada, oo saameeya shabkada korantada.impedance sifadu waxay sababtaa danab shaqeeya ee hadda garaaca wadnaha, taasoo keentay in ka baxsan-frame ee danab shaqada iyo hadda, halis geliyey tayada iyo ammaanka hawlgalka sahayda wareejinta, kordhinta khasaaraha line iyo leexashada danab shaqeeya, iyo isagoo saameyn taban oo ku saabsan shabakada korontada iyo qalabka korontada ee warshadda korontada lafteeda.
Isku-xidhka kumbuyuutarka ee barnaamijka kontoroolka (PLC) wuxuu u nugul yahay qalloocinta is-waafajinta ee tamarta shaqada ee sahayda beddelka.Waxaa guud ahaan lagu qeexay in wadarta guud ee garaaca wadnaha hadda shaqeeya ee khasaaraha jireed (THD) uu ka yar yahay 5%, iyo garaaca wadnaha shakhsi ahaaneed ee hadda shaqeeya Haddii heerka jirku uu aad u sarreeyo, qaladka hawlgalka ee nidaamka xakamaynta ayaa laga yaabaa inuu keeno hakad wax soo saarka ama hawlgalka, taasoo keentay shil mas'uuliyad wax-soo-saar oo weyn.
Marka bangiga capacitor magdhowga tamarta falcelinta la geliyo hawlgalka, sababtoo ah impedance sifo garaaca wadnaha hadda ee bangiga capacitor waa yar yahay, xaddi badan oo hadda garaaca wadnaha la soo bandhigay galay Halabuurka capacitor ah, iyo lacagta hadda balaadhi si degdeg ah, si halis ah u saameeyaa nolosha adeeg. .Dhanka kale, marka pulse capacitor-ka hadda jira ee bangiga capacitor uu u dhigmo inductor-ka hadda jira ee software-ka nidaamka, kororka harmonic hadda (2-10 jeer) waxay keeni doontaa in capacitorku uu kululeeyo oo uu burburiyo, iyo pulse current waxay keeni doontaa in inta jeer ee awooda wax soo saarka ay isbedesho.Waveform-ka sinusoidal-ka ayaa ka baxay qaab-dhismeedka, taasoo keentay hir-fiiqan oo qaab-muuqaal ah, oo waxay sababi doontaa dareere qayb ah oo ka yimaada walxaha lakabka dahaadhka ah, markaas oo ay dardargelinayso hufnaanta walxaha lakabka dahaadhka ah, oo waxyeello u geysta capacitor-ka.Sidaa darteed, golaha magdhawga korantada korantada ee kapacitor-ka looma isticmaali karo matoorka aan burushka lahayn ee DC iyo magdhowga korantada rogayaasha, iyo shaandhada leh shaqada xakamaynta garaaca wadnaha ee hadda waa in loo doortaa magdhowga tamarta falcelis yar.
Shaandhayso qorshaha daaweynta magdhowga awooda falcelinta
Yoolalka dowladnimada
Naqshadeynta qalabka magdhawga filtarku waxa uu buuxiyaa shuruudaha xakamaynta iswaafajinta iyo maaraynta awooda falcelinta.
Marka la eego habka 0.4KV ee habka hawlgalka, ka dib marka la geliyo qalabka magdhowga shaandhada, garaaca garaaca wadnaha ayaa la xakameynayaa, celceliska tamarta bishiiba waa 0.92.
Dhawaaqa is-waafajinta ee nidaamka sare leh, kororka dhawaaqa, iyo qulqulka xad dhaafka ah ee ay sababto isku xidhka wareegga laanta magdhowga filter ma dhici doonto.

Fikradaha naqshadeynta
Marka loo eego xaaladda gaarka ah ee shirkadda, shirkadeena waxay nashqadaysay matoor DC ah oo faahfaahsan iyo nidaamka shaandhada tamarta falcelinta ee jilicsan.Si buuxda uga fiirso qodobka awoodda culayska iyo xakamaynta iswaafajinta, oo ku rakib filtarrada dhinaca korantada hoose ee 0.4KV ee beddelka shirkadda ee magdhowga korantada falcelinta yar ee korantada si loo xakameeyo iswaafajinta, magdhowga tamarta falcelinta, iyo hagaajinta qodobka awoodda.Inta lagu jiro hawlgalka matoorka DC iyo rogaha, qalabka hagaajintu wuxuu soo saaraa 6K+1 harmonics sare.Ka dib marka hadda la gooyo oo la beddelo taxanaha Fourier, 5 jeer ee 250HZ iyo 7 jeer ee harmonics ka sarreeya 350HZ ayaa la soo saaray.Sidaa darteed, in design of inta jeer ee dhexdhexaadka ah foornada korontada shaandhada magdhow falcelinta falcelinta, waxaa lagama maarmaan ah in la naqshadeeyo soo noqnoqoshada 250HZ, 350HZ iyo wixii ka sareeya si loo hubiyo in laanta magdhow filter si wax ku ool ah u xakameeyo harmonics halka magdhow awoodda falcelinta iyo hagaajinta factor awoodda.
shaqada naqshadeynta
Awoodda dhammaystiran ee mashiinka DC-ga iyo khadka wax-soo-saarka soo-celinta soo noqnoqda ee u dhiganta 400KVA Transformer waxaa laga magdhabaa 0.7 ilaa in ka badan 0.95.Magdhowga filtarku wuxuu u baahan yahay in lagu dhejiyo awood 380kvar ah, kaas oo loo qaybiyay 4 kooxood oo awood ah oo si toos ah u gooyay si uu u magdhabo qalooca dhinaca hoose ee korantada ee isbeddelka siday u kala horreeyaan.Awoodda hagaajinta ee la kala soocay waa 45kvar, kaas oo la qabsan kara shuruudaha kala duwan ee tamarta khadka wax soo saarka, sidaas darteed naqshadeynta ayaa si buuxda u hubinaysa in awoodda la hagaajiyay ay ka sarreyso 0.9.
Falanqaynta saamaynta ka dib rakibidda magdhowga filtarka
Bishii Luulyo 2010, qalabka magdhawga korantada falcelinta shaandhada ee matoorada DC-ga iyo beddelayaasha soo noqnoqda ayaa la rakibay oo la hawlgeliyey.Qalabku wuxuu si toos ah ula socdaa isbeddelada culayska ee matoorada DC-ga iyo beddelayaasha soo noqnoqda, waxa uu xakameeyaa isku-habboonka-sarreeya wakhtiga dhabta ah, waxa uu magdhabaa awoodda fal-celinta, oo waxa uu wanaajiyaa qodobka awoodda.Faahfaahinta sida soo socota:
Ka dib marka la geliyo aaladda magdhowga shaandhada, qalooca qodobka awoodda ayaa isbeddelaya ka dib markii qalabka magdhowga shaandhada la geliyo qiyaastii 0.99 (qaybta kor loo qaaday waxay ku saabsan tahay 0.7 marka qalabka magdhowga filter laga saaro)
Hawlgalka load
Hadda uu isticmaalo 400KVA transformer-ka ayaa laga dhimay 770A ilaa 520A, hoos u dhac ah 33%.Magdhaw ka dib, qiimaha dhimista korantadu waa WT=△Pd*(S1/S2)2*τ*[1-(cosφ1/cosφ2)2]=5×{(0.7×400)400}2×0.4≈2.8( kw· h) Qaabka loo yaqaan 'Transformer', Pd waa lumitaanka muddada-gaaban ee Transformer-ka, kaas oo ah 5KW, kaydinta kharashaadka korontadu waa 2.8*20*30*10*0.7=11,700 yuan (oo ku salaysan shaqada 20 saacadood a maalin, 30 maalmood bishii, 10 bilood sannadkii, koronto kasta 0.7 yuan).
xaaladda factor awood
Xuquuqda guud ee shirkadda ayaa kor u kacday min 0.7 ilaa 0.95, qodobka xuquuqaha bilaha ahi waxa uu ku hadhay 0.96-0.98, ganaaxuna waxa uu ka kordhay 15,000 yuan bishii ilaa 3,000-5,000 yuan bishii.
Matoorka BLDC iyo shaandhada bilawga jilicsan
Qalabka magdhowga tamarta falcelinta ayaa awood u leh inuu xakameeyo garaaca wadnaha ee hadda jira oo uu magdhabo culeyska tamarta falcelinta, xalinta dhibaatada ciqaabta tamarta falcelinta, kordhinta mugga wax-soo-saarka transformer-ka, yareynta isticmaalka tamarta firfircoon, iyo kordhinta wax soo saarka, taasoo keenaysa faa'iidooyin dhaqaale oo muuqda. shirkadda iyo soo celinta maalgashiga mashruuca macaamiisha sanad ka hor.Sidaa darteed, shirkaddu waxay aad ugu qanacsan tahay magdhowga tamarta falcelinta ee matoorada DC-ga aan burushka lahayn iyo filtarrada rogayaasha, waxayna soo bandhigi doontaa macaamiisha qaarkood mustaqbalka.
