Macluumaadka aasaasiga ah ee isticmaalayaasha
Daawaynta bullaacadaha gudaha ee muhiimka ah ee shirkadda nadiifinta biyaha wasakhda ah, qayb ka mid ah sahayda tamarta beddelka ee khadka daawaynta biyaha wasakhda ayaa adeegsata matoorrada waditaanka soo noqnoqda ee DC, oo leh 1000KVA2, 630KVA transformers.Jaantuska nidaamka sahayda korontadu waa sida soo socota:
Xogta hawlgalka dhabta ah
Awooda wax soo saarka ee 1000KVA transformer jilcan waa 860KVA, celceliska awooda awooda waa PF=0.83, hada shaqaynaysa waa 1250A, hadda shaqaynaysa waa 630KVA, qodobka korantadu waa PF=0.87, wakhtiga xaadirka ahi waa 770A.Markaa wadarta guud ee tamarta waxay noqon kartaa kaliya 0.84.
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.Sidaa darteed, filtarka korantada falceliska hooseeya ee leh shaqada cadaadiska garaaca wadnaha hadda waa in loo adeegsadaa si loo xakameeyo garaaca wadnaha hadda ee nidaamka, magdhowga culeyska falcelinta, iyo hagaajinta qodobka awooda.
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
Sida laga soo xigtay xaaladda gaarka ah ee shirkadda, set oo ah qorshaha magdhow awoodda falcelinta ee shaandhada awoodda inverter ah in si buuxda u tixgalinaya factor awoodda culayska iyo cadaadiska garaaca hadda waxaa loo qaabeeyey, iyo set oo ah filter danab hoose ayaa lagu rakibay 0.4kV danab hoose. dhinaca Transformer-ka shirkadda Magdhowga korantada falcelinta si loo xakameeyo garaaca wadnaha hadda jira, magdhaba culayska falcelinta, iyo hagaajinta qodobka awoodda.
Ballastadu waxay soo saartaa 6K-1 garaaca garaaca wadnaha inta lagu jiro hawlgalka beddelaha, waxayna isticmaashaa isku xigxiga code caleen agagaarka 5250Hz iyo 7350Hz si loo fuliyo beddelka kala dirida.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 khadka wax soo saarka 1000KVA ayaa laga magdhabaa 0.8 ilaa 0.95.Qalabka magdhowga shaandhada wuxuu u baahan yahay in lagu rakibo mugga 380KVar, kaas oo loo qaybiyay afar kooxood, mid kasta oo ka mid ah si toos ah ayaa loo xirayaa oo go'ay, magdhowga caabbinta dabaysha ee dhinaca korantada hoose ee transformer-ka, oo leh mugga hagaajinta tallaabo ee 45KVAR, kaas oo lagu dhex dari karo shuruudaha awoodda wax soo saarka ee khadka wax soo saarka.Cunsurka awoodda dhamaystiran waxa laga magdhabaa 0.8 ilaa 0.95.Qalabka magdhowga shaandhada wuxuu u baahan yahay in lagu rakibo mugga 310KVar, afar kooxood ayaa si toos ah uga go'a si ay u magdhowaan dabaylaha dhinaca hoose ee transformer-ka, muggana waxaa lagu hagaajiyaa 26KVAR si loo buuxiyo shuruudaha tamarta shaqada ee khadka wax soo saarka.
Falanqaynta saamaynta ka dib rakibidda magdhowga filtarka
Bishii Agoosto 2010, shaandhaynta inverter-ka qalabka magdhowga 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 la isticmaalo 1000KVA Transformer waa laga dhimay 1250A ilaa 1060A, hoos u dhac 15% ah;hadda la isticmaalo 630KVA Transformer waxaa laga dhigay 770A ilaa 620A, hoos u dhac ah 19%.Magdhaw ka dib, qiimaha dhimista korantadu waa WT=△Pd*(S1/S2)2*τ*[1-(cosφ1/cosφ2)2]=24×{(0.85×2000)/2000}2×0.4≈16 (kw h) Qaaciddada, Pd waa luminta wareegga-gaaban ee transformer-ka, kaas oo ah 24KW, kaydinta kharashyada korantada ee sannadlaha ah waa 16*20*30*10*0.7=67,000 yuan (ku salaysan shaqada 20 saacadood a maalin, 30 maalmood bishii, 10 bilood sannadkii, 0.7 yuan halkii kWh).
