Marxaladan, qalabka qaybinta korantada iyo nidaamka qaybinta tamarta iyo qaybinta warshadaha petrochemical guud ahaan waxay isticmaalaan awooda AC ee nidaamka sahayda tamarta UPS.Ka dib markii laamo badan ay gacanta ku hayaan oo ay farsameeyaan kuwa korontada ku shaqeeya ee hooseeya, waxay soo saaraan 24V DC iyo 110V AC iyada oo loo marayo beddelayaasha AC/DC ama Transformers iyo qalab kale si ay u bixiyaan culeyska korantada ee muraayadaha u dhigma.
Sanduuqa wareejinta (sanduuqa) ee lagu rakibay warshadaha petrochemical waa in lagu rakibaa gudaha gudaha oo leh xaalado deegaan oo wanaagsan.Haddii loo baahdo rakibidda dibadda, meelaha leh jawi adag waa in laga fogaadaa, iyo sanduuqyada qaybinta (sanduuqyada) ee ku habboon heerarka deegaanka dabiiciga ah ee goobta rakibidda waa in la doortaa.
Baahida wax soo saarka awgeed, waxaa jira bambooyin badan oo bamka ah oo ku jira warshadaha petrochemical, iyo culeysyo badan oo bamka ah ayaa lagu qalabeeyaa bilawga jilicsan.Isticmaalka bilawga jilicsan ayaa sii kordhinaya nuxurka garaaca wadnaha ee nidaamka qalabka qaybinta tamarta ee warshadaha petrochemical.Waqtigan xaadirka ah, badi kuwa jilicsan ee bilawga ah waxay isticmaalaan 6 toosiye hal garaac ah si ay AC hadda ugu beddelaan DC, iyo is-waafajinta ka dhasha inta badan waa 5th, 7th iyo 11th harmonics.Waxyeellada harmonics ee nidaamka petrochemical software ayaa si gaar ah loogu muujiyey waxyeelada injineernimada tamarta iyo khaladka cabbirka saxda ah.Cilmi-baadhis cilmiyeed ayaa muujisay in qulqulka is-waafajinta ay sababi doonto khasaare dheeraad ah oo ku yimaada transformers, taas oo laga yaabo inay keento kulayl badan, dedejiso gabowga walxaha dahaadhka ah waxayna u horseedi kartaa waxyeelo.Joogitaanka hadda garaaca garaaca wadnaha ayaa kordhin doona awoodda muuqata waxayna saameyn xun ku yeelan doontaa waxtarka isbeddelka.Isla mar ahaantaana, harmonics waxay si toos ah u saameyn xun u leedahay capacitors, wareegyada wareegga, iyo qalabka ilaalinta gudbinta ee nidaamka korontada.Qalab badan oo tijaabo ah, xididka dhabta ah macnaheedu waa qiimaha labajibbaaran lama qiyaasi karo, laakiin celceliska qiimaha waa la qiyaasi karaa, ka dibna qaabka male-awaalka ah waxaa lagu dhuftaa tusaha togan si loo helo qiimaha akhriska.Marka harmonics-ku ay yihiin kuwo halis ah, akhrinta noocan oo kale ah waxay yeelan doontaa weecsanaan weyn, taasoo keenta weecsanaanta cabbirka.
Dhibaatooyin aad la kulmi karto?
1. Dhibaatooyinka bilawga ah ee fufiyeyaasha kala duwan iyo bambooyin
2. Beddelaha soo noqnoqda wuxuu abuuraa tiro badan oo harmonics ah, kaas oo saameeya hawlgalka badbaadada leh ee qalabka korantada ee nidaamka
3. Ganaax aan ansax ahayn oo ay sababto koronto yar (sida ku cad "Cabbirada Kharashka Kharashka Korontada ee Cunsurka Korontada" oo ay diyaariyeen Wasaaradda Khayraadka Biyaha iyo Korontada ee shirkadeena iyo Xafiiska Qiimaha ee shirkadeena).
4. Warshadaha petrochemical waa shirkad tamar badan cunta.Isbadalada ku yimid siyaasadaha isticmaalka korontada ee shirkadeena iyo qawaaniinta awgeed, waxaa laga yaabaa inay saamayso kala duwanaanshaha kharashka korontada.
Xalkayaga:
1. Ku rakib nooca hy-nooca sare ee tamarta falcelinta tooska ah qalabka magdhowga 6kV, 10kV ama 35kV ee nidaamka si loo magdhabo awoodda falcelinta nidaamka, hagaajinta factor awood, design heerka falcelinta wax ku ool ah, iyo qayb si toos ah u xakameeyo nidaamka garaaca wadnaha hadda;
2. Dhinaca korantada sare ee nidaamku waxay isticmaashaa nidaamka soo kabashada firfircoon ee tayada tayada leh si ay si firfircoon u magdhowdo culeyska falcelinta wakhtiga dhabta ah iyo ilaalinta kalsoonida tayada awoodda nidaamka;
3. Shaandheeyaha firfircoon ee Hongyan APF waxaa lagu rakibay dhinaca hoose ee 0.4kV si loo maareeyo nidaamka nidaamka, iyo qalabka magdhawga badbaadada badbaadada waxaa loo isticmaalaa in lagu magdhabo awoodda falcelinta ee nidaamka si loo hagaajiyo qodobka awoodda.
