Hawlgalka ku xiran shabakadda ee danab sareqalabka matoorka naaftada, caqligalka qaybinta korontada falceliska ah waxay si toos ah ula xiriirtaa xasilloonida cutubyada, badbaadada shabakadda korontada iyo cimriga adeegga qalabka. Annagoo ah shirkad diiradda saareysa hawlgalka iyo dayactirka qalabka korontada iyo adeegyada farsamada, waxaan isku darnaa khibrad wax ku ool ah oo goobta ah si aan si buuxda u falanqeyno arrimaha asaasiga ah, cilladaha caadiga ah iyo xalalka qaybinta korontada falceliska ah ee qalabka korontada dhaliya ee danab sare leh (10.5kV/6.3kV) ee ku xiran shabakadda, iyadoo bixinaysa tixraac wax ku ool ah oo loogu talagalay la-hawlgalayaasha warshadaha.
I. Mabaadi'da Aasaasiga ah: Dhismaha Muhiimka ah ee Qaybinta Awoodda Falcelinta
Marka la barbardhigo cutubyada danab-yar, macquulka aasaasiga ah ee qaybinta awoodda falgalka ah ee danab-sare ee ku xiran shabakaddaqalabka matoorka naaftadawaa isku mid, laakiin shuruudaha iswaafajinta xuduudaha iyo ilaalinta dahaarka ayaa aad u adag. Mabaadi'deeda asaasiga ah waxaa lagu soo koobi karaa saddex qodob: AVR Droop oo joogto ah, tixraaca kicinta isku midka ah, iyo xakamaynta hadda socota ee ku jirta meesha. Marka saddexdan mabda' la jebiyo, dhibaatooyinka sida dheelitir la'aanta awoodda falgalka ah, hadda socota ee xad-dhaafka ah, gariirka danabka, iyo xitaa qalabka AVR ama cutubka oo kululaada iyo turunturada ayaa u badan inay dhacaan, taasoo si dhab ah u saamaysa xasilloonida nidaamka isku xiran ee shabakadda.
Marka laga eego mabda'a, awoodda falgalka Q waxaa lagu go'aamiyaa hadda kicinta iyo danabka terminalka, waxayna hirgelisaa xakamaynta la isku xidhay oo leh awood firfircoon (oo uu maamulo guddoomiyaha). Marka hal cutub shaqeynayo, kororka hadda kicinta ayaa kordhin doona danabka terminalka, taas oo iyaduna kordhinaysa awoodda falgalka oo hoos u dhigaysa qodobka awoodda; marka cutubyo badan ay ku xiran yihiin shabag, danabka nidaamku waa mid gaar ah, cutub kastaa wuxuu u baahan yahay inuu qaybiyo awoodda falgalka iyadoo loo eegayo astaamaha hoos u dhaca Q-V (hoos u dhaca). Qaaciddada asaasiga ah waa (halka ay tahay dejinta danabka aan culayska lahayn, waa isku-dhafka hoos u dhaca, waana awoodda falgalka ee cutubka laftiisa).
Saddexda shuruudood ee muhiimka ah si loo hubiyo isku xirka shabakad deggan waa: dhammaan cutubyada waa in lagu dejiyaa hoos u dhac togan (, heerka caadiga ah 2%–5%), iyo hawlgal toos ah oo barbar socda oo aan lahayn hoos u dhac ama hoos u dhac taban waa mamnuuc; isku-dhafka hoos u dhaca ee cutub kasta waa inuu ahaadaa mid isku mid ah (jaangooyo isku mid ah cutubyada leh awood isku mid ah, iyo isku-dheelitirnaan ku habboon awoodda cutubyada leh awoodo kala duwan); danabka aan rarka lahayn waa in si joogto ah loo hagaajiyaa si looga fogaado qulqulka wareegga ee ku dhex jira.
II. Dhibaatooyinka Gaarka ah iyo Talooyinka Khatarta ah ee ku saabsan Isku xirka Shabakadaha Danab-sarreeya
Marka laga soo tago dhibaatooyinka caadiga ah ee cutubyada danab-yar, qaybinta awoodda falgalka ah ee qalabka matoorada naaftada ee danab-yaraha sare leh ee ku xiran shabakadda (10.5kV/6.3kV) waxay leedahay dhibaatooyinka soo socda ee gaarka ah ee u baahan in diiradda la saaro:
1. Shuruudaha Adag ee u Adkeysiga Dahaarka iyo Danabka
Heerka dahaarka ee nidaamyada kicinta danab-sare, aaladaha AVR, PT (Transformers-ka suurtagalka ah), CT (Transformers-ka hadda jira) iyo fiilooyinka isku xira waa inay la jaanqaadaan jawiga danab-sare; haddii kale, dhibaatooyin sida gurguurashada, burburka dahaarka iyo shaqada khaldan ee qalabka ayaa u badan inay dhacaan. Waxaa si gaar ah muhiim u ah in la ogaado in waxyeellada ka dhalata socodka tamarta falcelisa ee dhinaca danab-sare ay aad uga weyn tahay kan dhinaca danab-sare. Korontada xad-dhaafka ah ee wareegaysa waxay kordhin doontaa socodka stator-ka waxayna sababi doontaa kulayl badan oo dahaarka ah, taas oo iyaduna keenta cillado halis ah sida wareegga gaaban ee isku-xidhka iyo gubashada wareegga.
2. Saxnaanta iyo Fiilooyinka PT/CT Lama Iska indho tiri karo
Khaladaadka ku jira saamiga isbeddelka, kala-goynta iyo taxanaha wejiga ee PT iyo CT waxay horseedi doonaan qalloocinta muunadda AVR, taas oo iyaduna keenta khalkhal ku yimaada habaynta kicinta, ugu dambayntiina waxay keentaa dheelitir la'aan daran oo ah qaybinta awoodda falgalka ah iyo gariirka danabka. Isla mar ahaantaana, wareegga labaad ee CT ee dhinaca danabka sare waa mamnuuc in la furo, haddii kale waxay dhalin doontaa kumanaan volts oo xad-dhaaf ah, taasoo si toos ah u dhaawacaysa qalabka wareegga AVR iyo kantaroolka.
3. Is-waafajinta AVR Droop waa Khatar Qarsoon oo Caadi ah
Is-waafajinta isku-dhafka AVR ee hoos u dhaca waa sababta ugu badan ee keenta qaybinta awoodda aan sinnayn ee isku-xirka shabagga danab-sare: haddii farqiga isku-dhafka hoos u dhaca ee u dhexeeya cutubyada awoodda isku midka ah uu ka badan yahay 0.5%, qaladka qaybinta awoodda falgalka ah wuxuu ka badnaan doonaa 10%; haddii cutubyada awoodda kala duwan aysan u dejin isku-dhafka hoos u dhaca saamiga rogidda awoodda, cutubka weyn wuxuu noqon doonaa mid aad u badan oo cutubka yarna waxaa lagu buuxin doonaa awood falgal ah. Sababtoo ah qulqulka kicinta weyn ee cutubyada danab-sare, dhibaatooyinka kululaynta hadda socota iyo qalabka ee ay keento is-waafajinta hoos u dhaca ayaa aad u muuqan doona.
4. Kala duwanaanshaha Nidaamka Kicinta iyo Khataraha Isku xirka Shabakadaha ee Awoodda Dowladda Hoose
Haddii kicinta aan burushka lahayn iyo kicinta cadayga, kicinta isku-dhafka wejiga iyo kicinta la xakameyn karo lagu qaso cutubyada ku xiran shabagga, waxay horseedi doontaa astaamo dibadeed oo aan iswaafaqsanayn oo cutubyada ah, taasoo keenta kala-guurka qaybinta awoodda falgalka ah iyo xasillooni la'aanta danabka; kala duwanaanshaha is-hortaagga ee wareegyada kicinta ee cutubyada danabka sare waxay sidoo kale sababi doontaa hadda kicinta aan sinnayn, taas oo iyaduna horseedda dheelitir la'aanta awoodda falgalka ah. Intaa waxaa dheer, marka shabagga uu ku xiran yahay awoodda degmada (shabagga awoodda weyn, astaamaha aan hoos u dhicin),matoorka naaftadawaa in lagu dejiyaa hoos u dhac togan oo ah 3%–5%, haddii kale waxaa "ka soo bixi doona dheelitirka" shabakadda korontada, taasoo keenta dhibaatooyin sida dib-u-kicinta awoodda falgalka ah, dheregga AVR iyo turunturada cutubka; saxnaanta isku-dubaridka oo aan ku filnayn ee danabka, soo noqnoqoshada iyo wejiga ka hor isku xirka shabakadda ayaa sidoo kale sababi doonta khalkhal nidaamka kicinta, taasoo horseedaysa dheelitir la'aanta qaybinta awoodda falgalka ah.
III. Cilladaha Caadiga ah iyo Tilmaamaha Xallinta Dhibaatooyinka Degdegga ah
Hawlgalka goobta, dhacdooyinka cilladaha soo socda ayaa loo isticmaali karaa in si dhakhso ah loo helo dhibaatooyinka qaybinta awoodda ee falcelinta leh iyo in la hagaajiyo hufnaanta xallinta dhibaatooyinka:
- Ifafaalaha 1aad: Hal cutub wuxuu leeyahay awood falgal oo weyn iyo awood yar (tusaale ahaan, 0.7), halka cutubka kalena uu leeyahay awood falgal oo yar iyo awood sare (tusaale ahaan, 0.95) — Sababta ugu muhiimsan: Jiidashada AVR ee aan iswaafaqsanayn iyo dejinta danab aan culays lahayn.
- Ifafaalaha 2aad: Wareegga danabka ee xilliyeedka iyo hoos u dhaca awoodda falgalka ah ee dib-u-soo-noqoshada ka dib isku xirka shabagga — Sababta ugu muhiimsan: Isku-dhafka hoos u dhaca oo u dhow eber (aan hoos u dhac lahayn), hoos u dhac taban, ama nidaamka kicinta aan degganayn.
- Ifafaalaha 3aad: Ku-laabashada joogtada ah ee badhanka danab-sare, heerkulka stator-ka oo xad-dhaaf ah, iyo digniinta kulaylka badan ee AVR — Sababta ugu muhiimsan: Korontada wareegga awoodda oo xad-dhaaf ah, culayska korontada ee hal cutub, ama cilladda PT/CT.
- Ifafaalaha 4aad: Ka dib marka shabaqyada lala xiriiriyo korontada degmada, awoodda falgalka ee qalabka matoorka naaftada waa taban (nuugaya awoodda falgalka) iyo qodobka korontada ayaa hogaaminaya — Sababta ugu muhiimsan: Dejinta danabka ee qalabka matoorka naaftada ayaa ka hooseysa danabka shabaqyada, hoos u dhaca aad ayuu u yar yahay, ama kicinta ayaa ku filnayn.
IV. Xalalka Waxtarka leh ee Goobta
Iyadoo la hiigsanayo dhibaatada qaybinta awoodda falgalka ah ee qalabka matoorada naaftada ee danab sare leh ee ku xiran shabakadda, oo ay weheliso waayo-aragnimo wax ku ool ah oo goobta ah, waxaan ka bilaabi karnaa saddex cabbir: hagaajinta isku xirka shabakadda ka hor, hagaajinta isku xirka shabakadda ka dib, iyo maamulka danab sare leh ee gaarka ah si loo hubiyo qaybinta awoodda falgalka macquulka ah iyo hawlgalka nidaamka deggan.
1. Xidhiidhka Kahor Shabaqa: Qabashada Habaynta Joogtada ah ee Cabbirka
Habaynta cabbiraadda ka hor isku xirka shabagga ayaa ah aasaaska looga fogaanayo dhibaatooyinka qaybinta awoodda falcelinta leh. Saddex qodob oo muhiim ah ayaa loo baahan yahay in diiradda la saaro: marka hore, dejinta hoos u dhaca AVR. Isugeynta hoos u dhaca ee cutubyada leh awood isku mid ah waxaa lagu xakameeyaa 2%–5% (4%) caadiga ah, dhammaan cutubyaduna waa kuwo gebi ahaanba isku mid ah; cutubyada leh awoodo kala duwan, isku-dhafka hoos u dhaca waxaa loo dejiyay saamiga rogaal celinta ee awoodda (). Tusaale ahaan, cutub 1000kVA ah ayaa loo dejiyay 4%, cutub 500kVA ahna waxaa loo dejiyay 8%. Marka labaad, habaynta danab aan rarka lahayn. Danabka labaad ee PT ee dhinaca danabka sare waa midaysan yahay (tusaale ahaan, 100V), leexashada danabka aan rarka lahayn ee AVR waxaa lagu xakameeyaa gudaha ±0.5%. Saddexaad, kormeerka PT/CT. Hubi in saamiga isbeddelka, polarity-ga iyo taxanaha wejiga ay sax yihiin, hubi in saldhig la isku halleyn karo oo wareegga labaad ah, oo si adag u mamnuuc furitaanka wareegga labaad ee CT.
2. Xidhiidhka Kadib-shabakadda: Qaybinta Awoodda Falcelinta oo Si Sax ah u Hagaaji
Ka dib marka la xidho shabagga, mabda'a ah "dejinta awoodda firfircoon marka hore, ka dibna hagaajinta awoodda falgalka" waa in la raaco si tartiib tartiib ah loogu wanaajiyo qaybinta awoodda falgalka: marka hore, fiiri mitirka awoodda falgalka, mitirka awoodda iyo xogta mitirka danabka ee cutub kasta; haddii cutubku leeyahay awood falgal sare (qodob awood hoose), kicinta cutubka waa la dhimi karaa (qiimaha AVR ee hooseeya); haddii awoodda falgalku ay hooseyso (qodob awood sare leh), kicinta cutubka waa la kordhin karaa. Hadafka ugu dambeeya waa in la xaqiijiyo qaybinta awoodda falgalka iyadoo la eegayo awoodda, iyadoo qaladka qaybinta lagu xakameynayo gudaha ±10% (iyadoo la raacayo heerka GB/T 2820), leexashada danabka ≤±5%, iyo qodobka awoodda lagu hayo 0.8–0.9 oo dib u dhacaya. Haddii xaaladuhu oggolaadaan, shaqada qaybinta culeyska otomaatiga ah ee AVR (magdhawga khadka siman/wareegga hadda socda) ayaa la shidi karaa. Cutubyada danabka sare leh, khadadka siman ee DC (oo ah isla qaabka) ama xakamaynta hoos u dhaca awoodda falgalka ayaa la door bidaa si loo hagaajiyo saxnaanta hagaajinta.
3. Maamulka danab-sare ee gaarka ah: Xoojinta Ilaalinta iyo Dahaarka
Sida ku xusan astaamaha cutubyada danab-sare, tallaabooyin dheeraad ah oo loogu talagalay xakamaynta hadda socota iyo kor u qaadista dahaarka ayaa loo baahan yahay: rakib qalab kormeer iyo ilaalin hadda socota oo danab-sare leh, kaas oo xaqiijin doona digniin dib u dhac ah ama turunturooyin marka hadda socotadu ay ka sarreyso heerka (ka badan 5% ee hadda la qiimeeyay) si looga fogaado dhaawaca qalabka; wareegyada kicinta danab-sare leh, aaladaha AVR iyo fiilooyinka isku xira waxay qaataan heerka dahaarka F ama ka sareeya, tijaabooyinka u adkeysiga danab-korontada ayaa si joogto ah loo sameeyaa si loo hubiyo khataraha qarsoon ee dahaarka; qalabka matoorka naaftada-korontada sare leh ee isla goobta waa inay isku dayaan inay qaataan isla qaabka kicinta iyo qaabka AVR si looga fogaado astaamaha dibadda ee aan iswaafaqsanayn ee ka dhasha isku darka.
V. Xadka Caadiga ah iyo Talooyinka Ganacsiga
Sida ku cad heerka qaranka ee GB/T 2820, qaybinta awoodda falgalka ah ee qalabka matoorka naaftada ee danab sare leh ee ku xiran shabakadda waa inay buuxisaa xadka soo socda: qaladka qaybinta awoodda falgalka ah, ≤±10% cutubyada leh awood isku mid ah, ≤±10% cutubyada waaweyn iyo ≤±20% cutubyada yaryar ee leh awoodo kala duwan; heerka xakamaynta danabyada (hoos u dhaca) waxaa lagu xakameeyaa 2%–5% (hoos u dhaca togan), hawlgal toos ah oo is barbar socda oo aan lahayn hoos u dhac ama hoos u dhac taban waa mamnuuc; hadda wareegaya ≤5% ee hadda la qiimeeyay, kaas oo si adag loogu xakameynayo cutubyada danab sare leh.
Marka lagu daro sannado badan oo waayo-aragnimo warshadeed ah, waxaan soo jeedinaynaa in shirkaduhu si adag u raacaan mabaadi'da "hagaajinta isku xirka ka hor shabakadda, la socodka isku xirka ka dib shabakadda iyo dayactirka joogtada ah" marka qalabka matoorka naaftada ee danab sare leh uu ku jiro hawlgalka isku xirka shabakadda: diiradda saar hagaajinta isku-dhafka hoos u dhaca, danab aan culays lahayn iyo xuduudaha PT/CT ka hor isku xirka shabakadda; la socodka qaybinta awoodda falgalka waqtiga-dhabta ah, heerkulka wareegga hadda iyo qalabka ka dib isku xirka shabakadda; si joogto ah u ogaada oo u ilaali nidaamka kicinta iyo waxqabadka dahaarka si looga fogaado cilladaha la xiriira qaybinta awoodda falgalka ee ka imanaya isha iyo hubinta hawlgalka xasilloon ee cutubka iyo shabakadda korontada.
Haddii aad la kulanto dhibaatooyin gaar ah oo ku saabsan qaybinta korontada ee falceliska ah ee qalabka matoorada naaftada ee danab sare leh ee ku xiran shabakadda, waxaad la xiriiri kartaa kooxdayada farsamada, waxaanan ku siin doonnaa hagitaan iyo xalal toos ah goobta.
