Warshad duubitaan (qabow duuban) kiis

Macluumaadka aasaasiga ah ee isticmaalayaasha
Shirkadda birta duubta ayaa soo saarta silsilado bir ah oo dhumucdiisu tahay 0.5mm.Shirkaddu waxay leedahay 4 khadadka wax soo saarka, oo ay ku jiraan 1 loogu talagalay 650 birta ah iyo 3 loogu talagalay 450 mashiinnada birta ah.Awooda wadista qayb ahaan waxaa wata matoorada aan burushka lahayn ee DC, iyo 3 qaybood oo ah 1250KVA transformers iyo 630KVA ..Jaantuska nidaamka sahayda korontadu waa sida soo socota:

kiis-7-1

 

Xogta hawlgalka dhabta ah
Celceliska awooda korontadu waa 1250KVA Transformer waa PF=0.62, hadda shaqaynaysa 1960A iyo 630KVA Transformer waa 700KVA waa 5 jeer, saamiga isbeddelka mugga hadda waa 18.5%.

Falanqaynta Xaaladda Nidaamka Awoodda
Culayska ugu weyn ee mashiinka baabuurka burushka aan burushka lahayn ee DC waa 6 ballasts hal-pulse ah.Qalabka ballast-ku wuxuu abuuraa xaddi badan oo garaaca wadnaha hadda jira ee AC, AC, iyo hawlgallada DC.Waa isha caadiga ah ee garaaca wadnaha hadda.Marka la soo geliyo shabkada korantada, hadda is-waafajinta Wadnaha hadda shaqeeya ayaa sabab u ah cilladda sifaha shabakadda korantada, taasoo keentay in uu ka baxo korantada shaqada iyo hadda, taas oo khatar gelinaysa tayada iyo badbaadada hawlgalka Korontada wareejinta, waxay kordhisaa luminta khadka iyo leexashada tamarta shaqada, waxayna saameyn xun ku leedahay shabakadda korontada iyo qalabka korontada laftiisa.Sidaa darteed, magdhowga matoorka DC-ga aan burushka lahayn waa in uu isticmaalo magdhowga awoodda falcelinta ee korantada yar ee shaandhada xakamaynta garaaca wadnaha si loo magdhabo culeyska fal-celiska ah, loo hagaajiyo qodobka awoodda, oo aan lagu ciqaabi doonin awoodda falcelinta si loo kordhiyo wax soo saarka beddelka .

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, qorshe loogu talagalay magdhowga awoodda fal-celinta ee shaandhada shaandhada DC-ka waxaa loo qaabeeyey iyadoo la tixgelinayo awoodda culeyska iyo cadaadiska garaaca wadnaha ee hadda jira, iyo qayb ka mid ah shaandhada hoose ee magdhowga tamarta falcelinta ayaa lagu rakibay 0.4kV hoose. dhinaca danab ee Transformer , si loo xakameeyo hadda garaaca wadnaha, iyo mag load falcelinta, iyo hagaajinta factor awood.Ballastadu waxay soo saartaa 6K-1 garaaca garaaca wadnaha ee habka mashiinka DC bilaa burushka ah, waxayna isticmaashaa hadda cascaded si ay u milaan hadda, iyo hadda kala diri waa ilaa 5250Hz iyo 7350Hz.Sidaa darteed, naqshadeynta magdhowga awoodda falcelinta ee shaandhada foornada foornada soo noqnoqda ee dhexdhexaadka ah waa inay qaataan 250Hz, 350Hz iyo naqshadeynta inta jeer ee bartilmaameedka, si loo hubiyo in laanta magdhowga ee shaandhada ay si wax ku ool ah u xakameyn karto magdhowga garaaca wadnaha hadda, iyo isla wakhtigu waxa uu xakameeyaa culayska fal-celiska ah oo wanaajiya Cunsurka Korontada.

shaqada naqshadeynta
Awoodda guud ee 12500KVA DC ee khadka wax soo saarka buraashka ayaa laga magdhabaa 0.62 ilaa 0.95.Qalabka magdhowga shaandhada waa in lagu rakibaa mugga 1100KVar, kaas oo loo qaybiyay 10 kooxood oo magdhow beddelaad toos ah si loo magdhabo dabaylaha dhinaca korantada hoose ee beddelka.45KVAR wuxuu si tartiib tartiib ah u hagaajiyaa mugga si uu u buuxiyo shuruudaha awoodda wax soo saarka ee khadka wax soo saarka.630KVA Transformer DC khadka soo saarista mootada aan burushka lahayn Qodobka korantada dhamaystiran waxa laga magdhabaa 0.62 ilaa 0.95.Qalabka magdhowga shaandhada waa in lagu rakibaa mug dhan 600KVar, oo si toos ah u gooyaa dabaysha dhinaca hoose ee transformer-ka, iyo mugga si tartiib tartiib ah loo hagaajiyay ee 45KVAR, iyadoo la tixgelinayo shuruudaha korantada ee khadka wax soo saarka.

Falanqaynta saamaynta ka dib rakibidda magdhowga filtarka
Bishii Abriil 2010, shaandhaynta mootada DC ee qalabka magdhowga tamarta falcelinta ayaa la rakibay oo la hawlgeliyay.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:

kiis-7-3

 

Ka dib marka la isticmaalo aaladda magdhowga shaandhada, qalooca isbeddelka qodobka korantadu wuxuu ku saabsan yahay 0.99 (qaybta kor loo qaaday waxay ku saabsan tahay 0.6 marka qalabka shaandhada la saaro)

Hawlgalka load
Hadda la isticmaalo 1250KVA Transformer waa laga dhimay 1960A ilaa 1210A, hoos u dhac ah 38%.Hadda uu isticmaalo 1630KVA Transformer waxaa laga soo dhimay 1050A ilaa 657A, hoos u dhac ah 37.5%.Magdhaw ka dib, qiimaha dhimista korantadu waa WT=△Pd*(S1/S2)2*τ*[1-(cosφ1/cosφ2)2]=32×{(0.62×3000)3000}2×0.4≈15.8( kw· h) Qaabka loo yaqaan 'Transformer', waa 32KW, kaydinta kharashka korontadu waa 15.8*10*30*10*0.7=33,000 yuan (oo ku salaysan shaqada 20 saacadood maalin, 10 maalmood bishii, iyo 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 bishii waxa uu ku hadhay 0.96-0.98, mushaharka bishiina waa 3,000-4,000 yuan.
Matoorka DC-gu wuxuu awood u leeyahay inuu xakameeyo garaaca wadnaha ee hadda jira oo uu kabo culeyska tamarta falcelinta, xallinta dhibaatada ciqaabta tamarta falcelinta, kordhinta awoodda wax-soo-saarka ee qalabka wax-soo-saarka, hoos u dhigista luminta magdhowga awoodda firfircoon, kordhinta wax-soo-saarka iyo in la siiyo Shirkaddu waxay soo saartay faa'iidooyin dhaqaale oo muhiim ah, macmiilkuna wuxuu helay maalgelinta mashruuca in ka yar hal sano.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.
