Macluumaadka aasaasiga ah ee isticmaalayaasha
Shirkadda tuurista waalka gate waxay inta badan soo saartaa alaabada waalka.Qalabka khadka wax soo saarka ee shirkadda waxaa ka mid ah foorno soo noqnoqosho dhexdhexaad ah oo hal-ton ah, taas oo adeegsata 2000 kVA (10KV / 0.75 kVA) nidaamka qalabka korontada ee xirfadlayaasha farsamada, waxaana lagu qalabeeyaa laba armaajo magdhow capacitor ah oo leh mug dhan 600 kVA, a Hal tan oo foorno dhexdhexaadin ah oo dhexdhexaad ah, 800 kVA (10KV/0.4 kVA) nidaamka koronto-bixinta xirfadlayaasha farsamada, golaha magdhowga capacitor oo leh mugga 300 kVA.Jaantuska nidaamka sahayda korontadu waa sida soo socota:
Awoodda muuqata ee foornada soo noqnoqda soo noqnoqda ee dhexdhexaadka ah ee ku qalabaysan 2000KVA Transformer waa 700KVA-2100KVA, awoodda firfircooni waa P=280KW-1930KW, culeyska falcelinta waa Q=687KAR-830KAR, awoodda korontada waa PF=0.4-0.92, iyo hadda shaqeeyaⅰ = 538 A-1660 A, awoodda muuqata ee foornada induction soo noqnoqda dhexdhexaadka ah oo ku qalabaysan 800KVA transformer waa 200KVA-836KVA.Awoodda firfircooni waa P = 60KW-750KW, culeyska falcelinta waa Q=190KAR-360KAR, awoodda korontadu waa PF=0.3-0.9, iyo hadda shaqeeya i=288 A-1200 A. Sababtoo ah golaha magdhowga capacitor lama gelin karo Hawlgalka ( magdhow otomaatig ah ayaa ku guuldareysta, marka capacitor gacanta lagu geliyo, sanqadha capacitor waa mid aan caadi ahayn, wareegtada safraan, capacitor waa la baakadeeyey, saliid daadin, dildilaac, oo aan la isticmaali karin), awoodda bilaha ah ee dhamaystiran Qodobku waa PF=0.78, iyo heerka dulsaarka amaahda guryaha bishiiba waxaa lagu hagaajiyay in ka badan 32,000 yuan.
Falanqaynta Xaaladda Nidaamka Awoodda
Culayska muhiimka ah ee sahayda korantada ee la hagaajiyay ee foornada induction soo noqnoqda ee inta jeer ee dhexdhexaadka ah waa lix ballastada garaaca wadnaha ah.Qalabka hagaajintu waxa uu soo saaraa is-waafajin badan marka uu u beddelo AC hadda una beddelo DC, taas oo ah isha caadiga ah ee harmonics.Xakamaynta hadda jirta ee lagu soo bandhigay korantada korantada waxay sababi doontaa danab shaqeynaya iswaafajin oo ku saabsan is-hortaagga dabeecadda korantada, taasoo keentay luminta korantada shaqada iyo hadda ee korontadu, khatar gelinaysa tayada iyo badbaadada hawlgalka nidaamka bixinta korantada, kordhinta luminta khadka iyo leexashada korantada shaqaynaysa, iyo dhaawac u geysta shabkada korantada iyo habaynta Qalabka korontada ee warshadu leedahay waxay keeni doontaa khataro aan wanaagsanayn.Marka bangiga capacitor ee magdhowga tamarta falcelinta la geliyo shaqada, sababtoo ah is-hortaagga sifada harmonic ee bangiga capacitor waa yar yahay, tiro badan oo harmonics ah ayaa lagu soo bandhigaa bangiga capacitor, iyo awoodda hadda jirta ayaa si degdeg ah u kordheysa, si dhab ah u saameeya nolosha adeegga.Dhanka kale, marka falcelinta capacitive harmonic ee bangiga capacitor ay la mid tahay falcelinta inductive inductive ee u dhiganta ee nidaamka iyo resonance taxane ah ayaa dhacaya, hadda harmonic ayaa si weyn u weynaaday (2-10 jeer), taasoo keentay in kulayl iyo dhaawac capacitor-ka.Intaa waxaa dheer, harmonics-ku waxay keeni doontaa in mawjada sinusoidal DC ay isbeddelaan, taas oo keenta mowjadda ugu sarreysa ee sawtooth, taas oo ay fududahay in ay keento dheecaan qayb ah walxaha dahaarka.Dheecaan qayb ka mid ah muddada-dheer wuxuu sidoo kale soo dadajin doonaa gabowga walxaha dahaarka oo si fudud u sababi doona dhaawaca capacitor.Sidaa darteed, golaha magdhowga tamarta falcelinta capacitor looma isticmaali karo magdhowga foornada induction soo noqnoqda ee dhexdhexaadka ah, waxaana la doortaa qalab magdhow koronto falgal ah filtar leh oo leh shaqada xakamaynta garaaca wadnaha hadda.
Qorshaha daawaynta magdhowga awooda falcelinta
Yoolalka dowladnimada
Aaladaha magdhawga shaandhaynta waxaa loogu talagalay inay buuxiyaan shuruudaha sharci ee xakamaynta iswaafajinta iyo awoodda falcelinta.
Qaabka hawlgalka ee nidaamyada 0.75KV iyo 0.4KV, ka dib markii qalabka magdhowga shaandhada uu ka tago warshadda, harmonics-dalab sare ayaa lagu xakameynayaa celceliska awoodda bilaha ah ee 0.95 ama ka badan.
Gelitaanka wareegga magdhowga shaandhada ma keenayso garaaca garaaca hadda jira ama kor u kaca dhawaaqa iyo qulqulka.

Fikradaha naqshadeynta
Marka loo eego xaalada gaarka ah ee shirkadu, shirkadeena waxay nashqadaysay nidaam tafatiran oo tafatiran oo soo noqnoqonaya foornada soo noqnoqda ee nidaamka shaandhada korontada.Si buuxda uga fiirso qodobka awoodda culayska iyo xakamaynta iswaafajinta, oo ku rakib shaandhada magdhawga korantada yar ee korantada hoose ee dhinaca korantada ee shirkadda 0.75KV iyo 0.4KVInta lagu jiro hawlgalka foornada soo noqnoqda ee dhexdhexaadka ah, qalabka hagaajinta wuxuu soo saaraa 6K + 1 harmonics, iyo taxanaha Fourier waxaa loo isticmaalaa in lagu jajabiyo oo loo beddelo hadda si loo dhaliyo 5 harmonics ee 250HZ iyo 7 harmonics ka sarreeya 350HZ.Sidaa darteed, qaabaynta soo noqnoqoshada soo noqnoqoshada foornada foornada dhexdhexaadinta magdhowga falcelinta falcelinta, inta jeer ee 250HZ, 350HZ iyo agagaarka waa in loo qaabeeyaa si loo hubiyo in wareegga magdhowga shaandhada uu si macquul ah u xakameyn karo garaaca garaaca wadnaha halka magdhowga culeyska falcelinta iyo hagaajinta qodobka awoodda.
shaqada naqshadeynta
Awoodda guud ee 2-tan foornada induction soo noqnoqda ee dhexdhexaadka ah oo la mid ah 2000 kVA transformer ayaa magdhow laga bilaabo 0.78 ilaa 0.95.Qalabka magdhowga shaandhada wuxuu u baahan yahay in lagu qalabeeyo awood dhan 820 kVA, wuxuuna si toos ah ugu beddelaa 6 kooxood oo awood ah, kuwaas oo mid kastaa uu ku habboon yahay dabaysha dhinaca korantada hoose ee beddelka magdhowga.Awoodda kala-soocidda kala-soocidda waa 60KVAR, kaas oo buuxin kara shuruudaha awoodda kala duwan ee foornada soo-celinta soo noqnoqda ee dhexdhexaadka ah.Awoodda guud ee 1 tan foornada soo noqnoqoshada soo noqnoqda ee dhexdhexaadka ah oo la mid ah koronto-bixiyaha 800 kVA ayaa laga magdhabaa 0.78 illaa 0.95.Qalabka magdhowga shaandhada wuxuu u baahan yahay in lagu qalabeeyo awoodda 360 kVA, kaas oo si toos ah loogu beddeli karo 6 kooxood oo awood ah, awoodda hagaajinta ee darajadu waa 50 kVA, taas oo buuxin karta shuruudaha tamarta kala duwan ee foornada soo noqnoqda ee dhexdhexaadka ah.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
Bilowgii Juun 2010, shaandhada foornada inta jeer ee dhexdhexaadka ah ayaa la rakibay oo la hawlgeliyey.Qalabku wuxuu si toos ah ula socdaa isbeddelka culeyska foornada soo noqnoqda ee soo noqnoqoshada dhexdhexaadka ah, gaar ahaan magdhowga culeyska falceliska ah, wuxuuna wanaajiyaa qodobka awoodda.Faahfaahinta sida soo socota:
Ka dib marka la shido qalabka magdhowga shaandhada, qalooca isbeddelka qodobka korantadu wuxuu ku saabsan yahay 0.97
Hawlgalka load
Xilliga hadda jira ee 2000KVA waa laga dhimay 1530A ilaa 1210A, hoos u dhac 21% ah;hadda 800KVA Transformer waxaa laga dhigay 1140A ilaa 920A, hoos u dhac ah 19.3%, taasoo la mid ah hoos u dhac 20% ee Transformer, taas oo ah, 560KVA, iyo waxyeelada soo saarka korontada ka dib markii magdhow la dhimay 21%.;Burburka beddelka waxaa hoos u dhigay WT=?Pd1S2) 2**[1-(1-1/cos2)2]=24{(0.78?2800)/280}20.415(kwh).Khasaaruhu waa 24 yuan, khasaaruhuna bishii waa 15KW=150d;Qiimaha kaydinta bishii waa 1580d=230d*30d(2307){0.782800}20d.
xaaladda factor awood
Bishan, saamiga guud ee shirkadda ayaa kor u kacay min 0.78 ilaa 0.97, heerka falcelinta bilaha ah iyo biilasha tamarta ayaa lagu hagaajiyay 0, waxaana loo bedelay ganaaxa 4,680 yuan.Tan iyo markaas, qodobka awoodda bilaha ah wuxuu ku haray 0.97-0.98, abaal-marintii bishiina waxay ahayd inta u dhaxaysa 3,000-5,000 yuan.
Guud ahaan, sheygani waxa uu leeyahay awood aad u fiican si uu u xakameeyo garaaca wadnaha ee hadda iyo magdhow awoodda falcelinta, xalliyo dhibaatada muddada dheer ee shirkadda ee dulsaarka dulsaarka dulsaarka iyo ganaaxa khidmadda utility, wanaajiso awoodda wax soo saarka ee Transformers, iyo in faa'iidooyin dhaqaale oo cad u keeno shirkadda . Maalgelinta macmiilka in ka yar hal sano.Sidaa darteed, magdhowga tamarta falcelinta ee foornada soo noqnoqda ee dhexdhexaadka ah ee ay soo saartay shirkadu waa mid aad u qanacsan, waxayna soo jiidan doontaa macaamiil badan mustaqbalka.
