Macluumaadka aasaasiga ah ee isticmaalayaasha
Warshada petrochemical waxay inta badan soo saartaa alaab gaas ah.Qalabka korontada ee shirkadu isticmaasho ayaa ah darawal jilicsan oo bilawga ah, iyo qalabka qaybinta qaybinta waa 2500 kVA.Jaantuska nidaamka sahayda korontadu waa sida soo socota:
Xogta hawlgalka dhabta ah
Wadarta awoodda beddelka soo noqnoqda ee 2500KVA Transformer waa 1860KVA, celceliska awoodda korontadu waa PF=0.8, hadda shaqeeyana waa 2400-2700A.
Falanqaynta Xaaladda Nidaamka Awoodda
Furaha sahayda korontadu waa culeyska darawalka korantada inverter-ka, kaas oo iska leh culeyska nidaamka kala duwan.Qalabku wuxuu soo saaraa is-waafajin badan inta lagu jiro habka hawlgalka, kaas oo ah isha caadiga ah ee is-waafajinta.Xakamaynta hadda jirta ee lagu soo bandhigay korantada korantada waxay sababi doontaa danab shaqeynaya iswaafajin oo ku saabsan cilladda sifaha korantada, taasoo keentay isbedbeddelka korantada shaqada iyo hadda ee korantada, taasoo khatar gelinaysa tayada iyo badbaadada hawlgalka nidaamka bixinta korantada, kordhinta luminta khadka iyo khaladka danabku shaqaynayo, oo waxyeello weyn u geysta shabkada korontada iyo warshadaynta.Qalabkeeda korantada, gaar ahaan golaha magdhowga tamarta falcelinta ee dhaqameed waxay keeni doontaa saameyn xun, wayna fududahay in la sameeyo gariir iswaafajin ah, taasoo waxyeelo u gaysanaysa qalabka korantada sida armaajooyinka capacitor-ka.Sidaa darteed, shaandhada korantada falceliska hooseeya ee leh shaqada xakamaynta iswaafajinta waa in la doortaa si loo xakameeyo habraaca habraaca, magdhowga culeyska falcelinta, iyo hagaajinta qodobka awoodda.
Shaandhayso qorshaha daaweynta magdhowga awooda falcelinta
Yoolalka dowladnimada
Aaladaha magdhawga shaandhaynta waxaa loogu talagalay inay buuxiyaan shuruudaha sharci ee xakamaynta iswaafajinta iyo awoodda falcelinta.
Marka loo eego qaabka hawlgalka 0.4KV, ka dib marka qalabka magdhowga shaandhada uu ka tago warshadda, xakamaynta iswaafajinta ayaa ka sarreysa 0.92 celceliska tamarta bilaha ah.
Ha keenin resonance is-waafaqsan ama kororka resonance iyo qulqulka xad-dhaafka ah sababtoo ah laanta magdhowga galinta galinta.

Fikradaha naqshadeynta
Marka loo eego xaaladda dhabta ah ee shirkadda, shirkadeena waxay si buuxda u tixgalinaysaa qodobka awoodda culeyska iyo xakamaynta iswaafajinta ee shaandhada magdhowga aan ansax ahayn ee rogaha, waxayna ku rakibtaa shaandhada aaladda magdhowga aan ansax ahayn ee 0.4KV dhinaca korantada hoose ee beddelka ganacsiga, kaas oo wuxuu xakameeyaa harmonics wuxuuna magdhabaa kororka awoodda falcelinta.factor awood.
Inta lagu jiro hawlgalka beddelka soo noqnoqda, waxay dhalin doontaa 5 jeer 250HZ, 7 jeer 350HZ iyo kuwa kale oo amar sare leh.Sidaa darteed, marka la naqshadeynayo shaandhada magdhowga aan waxtarka lahayn ee rookaha, waa in la hubiyaa in wareegga laanta magdhowga filterku uu si wax ku ool ah u xakameyn karo harmonics iyo magdhowga awoodda aan waxtarka lahayn ee isdabajoogga ka sarreeya 250HZ iyo 350HZ si loo hagaajiyo qodobka awoodda.
shaqada naqshadeynta
Awoodda guud ee laynka wax-soo-saarka korantada roga-rogayaasha oo la mid ah koronto-bixiye kasta oo 2500 kVA ah ayaa laga magdhabaa 0.8 illaa 0.92.Qalabka magdhowga qalabka sifaynta waa in lagu rakibaa awood ah 900 kWh.Awoodaha 11 kooxood ee weji-kala qaybinta waxay la mid yihiin dabaylaha dhinaca korantada hoose ee transformer-ka si loogu xidho oo si toos ah loo gooyo.Awoodda hagaajinta kala-saarku waa 45KVAR, kaas oo buuxin kara shuruudaha tamarta kala duwan ee bilowga jilicsan iyo khadadka wax soo saarka.Naqshadaynta noocan oo kale ah waxay si buuxda u dammaanad qaadaysaa in awoodda la hagaajiyay ay ka sarreyso 0.95.
Falanqaynta saamaynta ka dib rakibidda magdhowga filtarka
Bishii Juun 2011, qalabka magdhawga korantada falcelinta shaandhada beddelka ayaa la rakibay oo la hawlgeliyay.Qalabku wuxuu si toos ah ula socdaa isbeddelka culeyska rogaha, isla markiiba wuxuu xakameynayaa heerka sare ee garaaca wadnaha si uu u magdhabo culeyska falcelinta, wuxuuna wanaajiyaa qodobka awoodda.Faahfaahinta sida soo socota:
Kadib marka la isticmaalo aaladda magdhowga shaandhada, qalooca isbeddelka qodobka korantadu wuxuu ku saabsan yahay 0.98 (qaybta kor loo qaaday waxay ku saabsan tahay 0.8 marka qalabka shaandhada la saaro)
Hawlgalka load
Awoodda hadda shaqaynaysa 2500KVA Transformer waa laga dhimay 2700A ilaa 2300A, heerka dhimashaduna waa 15%.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 sannadlaha ah waa 16*20*30*10*0.7*2=134,000 yuan (oo ku salaysan shaqada 20) saacadaha maalintii, 30 maalmood bishii, iyo 10 bilood sannadkii, 0.7 yuan halkii kWh).
xaaladda factor awood
Korontada guud ee shirkadu waxay kor u kacday 0.8 ilaa 0.95 bishan, waxaana awooda korontada lagu hayn doonaa 0.96-0.98 bisha soo socota, abaalmarintana waxaa lagu kordhin doonaa 5000-6000 yuan bisha Janaayo.
Guud ahaan, magdhowga korantada-yar ee awoodda falcelinta ee filtarka jilicsan ayaa leh awood aad u wanaagsan oo lagu xakameynayo garaaca wadnaha hadda iyo magdhowga awoodda falcelinta, xallinta dhibaatada ciqaabta awoodda falcelinta ee shirkadda, kordhinta mugga wax soo saarka ee transformer, iyo in la yareeyo awoodda firfircoon Isticmaalka dheeriga ah ee badeecadu waxay kordhisay wax soo saarka, waxay u keentay faa'iidooyin dhaqaale oo muuqda shirkadda, waxayna dib u soo ceshatay maal-gashiga macaamilka hal sano gudaheed.Sidaa darteed, shaandhada jilicsan ee jilicsan ee magdhowga tamarta falcelinta ee ay soo saartay shirkadu waa mid aad u qanacsan, waxayna soo jiidan doontaa macaamiisha badan mustaqbalka.
