Macluumaadka aasaasiga ah ee isticmaalayaasha
Warshada sibidhka waxay soo saartaa shubka dhismaha ee kala duwan.Shirkaddu waxay leedahay 3 khadadka wax soo saarka.Korontada wareejinta waxay isticmaashaa matoorrada wadida, 2000KVA2, 630KVA Transformers, transformer kastaa wuxuu ku qalabaysan yahay golaha magdhowga capacitor ee dhinaca cadaadiska hoose.Jaantuska nidaamka sahayda korontadu waa sida soo socota:
Xogta hawlgalka dhabta ah
Awoodda wax soo saarka ee bilowga jilicsan ee 2000KVA Transformer waa 1720KVA, celceliska awoodda awoodda waa PF = 0.83, hadda shaqeeyaa waa 2500A, korantadu waa 530KVA630KVA transformer, celceliska awoodda tamarta waa PF = 0.87, iyo shaqada hadda waa 770A.Golaha magdhawga tamarta falceliska ah ee hoos yimaada transformer kasta ayaa inta badan leh safarro koronto,caafimaadka saliidda,iyo guddiga kontoroolka oo soo bandhiga macluumaadka aan ogolayn hawlo aan caadi ahayn.Sidaa darteed, qodobka awoodda guud waa 0.84 oo keliya, iyo ciqaabta awoodda falcelinta waxay ku saabsan tahay 20,000 Janaayo.Iyo matoorada khadka wax soo saarka iyo kuwa bilawga jilicsan ayaa mararka qaarkood carqaladayn kara wax soo saarka.
Falanqaynta Xaaladda Nidaamka Awoodda
Culayska ugu weyn ee ballast-ka beddelka waa 6 ballasts hal-pulse ah.Qalabka ballast-ku wuxuu soo saaraa xaddi badan oo garaaca wadnaha ah ee shaqada u beddelashada AC ilaa DC.Waa isha caadiga ah ee garaaca wadnaha waxaana la gelinayaa shabkada korantada.Xalalka harmonic waxay sababaan koronto shaqeyneysa garaaca wadnaha si ay u noqoto caabbinta sifada shabkada korantada, taasoo keentay luminta qaab dhismeedka korantada shaqada iyo hadda, khatarta tayada iyo badbaadada hawlgalka ee wareejinta sahayda korantada, kordhinta luminta khadka iyo leexashada korantada shaqada, iyo keenista saameyn taban Shabakadda korontadda iyo dhirta korontadu laftooda ayaa saameyn ku yeesha.
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 magdhowga korantada rogayaasha, iyo shaandhada leh shaqada xakamaynta garaaca wadnaha ee hadda waa in loo doortaa magdhowga tamarta falcelinta yar-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.

fikradda naqshadeynta
Sida laga soo xigtay xaaladda gaarka ah ee shirkadda, factor awoodda iyo cadaadiska garaaca wadnaha hadda waxaa loo arkaa in magdhow filter ee sahayda inverter ah, iyo qalabka magdhow fashilka filtarrada waxaa la dhigay on 0.4kV dhinaca danab hoose ee transformer ah, kaas oo xakamayn kara garaaca garaaca wadnaha iyo magdhow hagaajinta factor awood.
Beddeliyaha, ballast-ku wuxuu soo saaraa 6K-1 qulqulo garaaca wadnaha horumarsan iyadoo loo eegayo socodka hadda socda ee Fourier, ka dibna wuxuu soo saaraa 5 qulqulo garaac oo horumarsan, mid kasta oo ku saabsan 250Hz iyo 7350Hz.Sidaa darteed, marka la naqshadeynayo magdhowga tamarta falcelinta ee foornooyinka soo noqnoqda ee dhexdhexaadka ah, waxaa lagama maarmaan ah in la naqshadeeyo soo noqnoqoshada agagaarka 250Hz iyo 350Hz si loo hubiyo in laanta magdhowga shaandhada ay si wax ku ool ah u xakameyn karto qulqulka garaaca wadnaha, magdhowga culeyska falcelinta isla mar ahaantaana, iyo hagaajinta qodobka awoodda.
shaqada naqshadeynta
Awoodda guud ee laynka korantada ee isku xidhan ee 2000kV AC Transformer waxa laga magdhabaa 0.8 ilaa 0.95.Qalabka magdhowga shaandhada waa in lagu qalabeeyaa mug dhan 760kV, oo si toos ah loogu beddelaa 8 qaybood oo mugga, iyo hal set ayaa la shaqeeya magdhowga dabaysha ee dhinaca korantada hoose ee beddelka.Culayska shaqada ee hagaajinta fasalka waa 45KVAR, kaas oo buuxin kara shuruudaha tamarta kala duwan ee khadka wax soo saarka.Awoodda guud ee 630kV khadka beddelka isku xidhka ah waa la magdhabay, qiyaasta magdhowgu waa 0.8 ilaa 0.95.Qalabka magdhowga shaandhada waa in lagu qalabeeyaa mugga 310kV, kaas oo si toos ah loogu beddelayo afar qaybood oo mugga, iyo hal set ayaa la shaqeeya iska caabiyaha dabaysha ee dhinaca korantada hoose ee beddelka magdhowga.Culayska shaqada ee hagaajinta fasalka waa 26KVAR, kaas oo buuxin kara shuruudaha tamarta kala duwan ee khadka wax soo saarka.Naqshadeynta nidaamku waxay si buuxda u dammaanad qaadaysaa in qodobka korantadu uu dhaafo 0.95.
Falanqaynta saamaynta ka dib rakibidda magdhowga filtarka
Bishii Luulyo 2010, shaandhaynta inverter-ka qalabka magdhawga tamarta falcelinta ayaa la rakibay oo la hawlgeliyay.Qalabku wuxuu si toos ah ula socdaa isbeddelka culeyska rogaha, wuxuu xakameyaa is-waafajinta nidaamka sare ee waqtiga dhabta ah, wuxuu magdhabaa awoodda falcelinta, wuxuuna wanaajiyaa qodobka awoodda.Faahfaahinta sida soo socota:
Ka dib marka la isticmaalo aaladda magdhowga shaandhada, qalooca qodobka awoodda ayaa isbeddelaya ka dib markii qalabka magdhowga shaandhada la geliyo qiyaastii 0.97 (qaybta kor loo qaaday waxay ku saabsan tahay 0.8 marka qalabka shaandhada la saaro)
Hawlgalka load
Hadda ay isticmaalaan 2000KVA Transformers waxaa laga dhimay 2500A ilaa 2120A, hoos u dhac 15% ah;hadda ay isticmaalaan 630KVA Transformers waxaa laga dhigay 770A ilaa 620A, hoos u dhac ah 19%.Ka dib magdhowga, dhimista tamarta-yarida ValueisWT=△Pd*(S1/S2)2*τ*[1-(cosφ1/cosφ2)2]=50×{(0.85×4500)/4500}2×0.4≈34(kw h) formula, Pd waa lumitaanka gaaban ee transformerka, kaas oo ah 50KW, iyo kaydinta kharashka koronto sanadlaha ah 34*20*30*10*0.7=142,800 yuan (oo ku salaysan shaqada 20 saacadood maalintii, 30 maalmood bishii. , 10 bilood sannadkii, 0.7 yuan halkii kWh).
xaaladda factor awood
Tilmaanta injineernimada tamarta guud ee shirkadda ayaa kor u kacday min 0.8 ilaa 0.95, iyo tusmada injineernimada tamarta bishiiba waxa ay joogtay 0.96-0.98, taas oo ka soo kacday in ka badan 20,000 yuan bishii ilaa in ka badan 6,000-10,000 yuan bishii.
Magdhawga awoodda falcelinta yar ee korantada ee filtarka beddelka soo noqnoqda ayaa awood u leh inuu xakameeyo garaaca wadnaha hadda oo uu magdhabo culeyska falcelinta, xallinta dhibaatada ciqaabta tamarta falcelinta, kordhinta awoodda wax soo saarka ee beddelka, hoos u dhigida luminta magdhowga awoodda firfircoon, kordhinta wax soo saarka, oo faa'iido u leh shirkadda Faa'iidooyin dhaqaale oo muuqda ayaa la soo saaray, maal-gelinta mashruuca macmiilku waa wax ka yar hal sano oo uu helay maalgelinta mashruuca.Sidaa darteed, shirkaddu aad ayay ugu qanacsan tahay magdhowga tamarta falcelinta ee shaandhada beddelka, waxayna soo bandhigi doontaa macaamiisha qaarkood mustaqbalka.
