Qhov project Background
Liunan Second Expressway tseem hu ua Liuzhou Jingheshan rau Nanning Expressway.Txoj kab tseem ceeb ntawm txoj haujlwm no pib los ntawm thaj tsam ntawm Luoman Town, Liuzhou City, txuas Liuzhou Expressway los ntawm Sanjiang, thiab thaum kawg tuaj txog ntawm Wutang Town, Nanning City, thiab Liuzhou South Expressway.Txoj kev loj yog ib txoj kev loj uas muaj tsheb loj tshaj plaws hauv Guangxi nyob rau xyoo tas los no.Txoj kev thib ob hauv Liunan City muaj tag nrho ntev li ntawm 199 km thiab tsim ceev ntawm 120 km ib teev.Nws siv ob txoj kab plaub txoj kab thiab tsim 8 kab sib txuas tib lub sijhawm.Tag nrho cov peev nyiaj kwv yees yog 20.749 billion yuan.Muaj 13 tus choj, 4 qhov chaw pabcuam, 3 Tom qab txoj haujlwm qhib rau kev tsheb, lub sijhawm tsav tsheb los ntawm Shanglin mus rau Nanning yuav luv luv mus rau 1 teev, txo cov tsheb khiav ceev ntawm thawj Liunan Expressway, tshwj xeeb tshaj yog los ntawm Liujing mus rau San'an.
Daim ntawv thov
Qhov project no siv peb lub tuam txhab reactive fais fab nyiaj them nyiaj series cov khoom, nrog rau static var generators, ntse ua ke anti-harmonic them nyiaj pab kiag li lawm, thiab lwm yam. Feem ntau yog siv rau reactive zog them.Txhim kho lub zog zoo, txo qhov poob, thiab ua kom ruaj khov thiab txhim khu kev lag luam ntawm cov khoom siv fais fab.
Qhov zoo ntawm static var generator khoom
1. Capacitive inductive load -1 ~ 1 nyiaj them.
2. Peb-theem unbalance them nyiaj.
3. Kev ua haujlwm hloov zaus yog 10K, thiab cov nyiaj them poob haujlwm yog cov lus teb ceev heev.
Lub HYSVG static var generator pom cov load tam sim no nyob rau hauv lub sij hawm ntawm lub sab nraud tam sim no transformer (CT), soj ntsuam cov reactive zog cov ntsiab lus ntawm lub load tam sim no los ntawm lub internal DSP xam, thiab ces tswj lub PWM teeb liab generator xa ib tug tswj teeb liab mus rau lub sab hauv IGBT raws li tus nqi teev.Ua kom lub inverter tsim reactive zog them tam sim no uas ua tau raws li qhov yuav tsum tau, thiab thaum kawg paub lub hom phiaj ntawm dynamic reactive fais fab nyiaj them.
HY series ntse ua ke ua ke los tiv thaiv kev sib raug zoo nrog cov khoom siv hluav taws xob tsawg-voltage capacitor them nyiaj yog lub cim tshiab ntawm cov khoom siv hluav taws xob siv hluav taws xob siv hauv 0.4KV qis-voltage tis network rau kev ua haujlwm siab, txuag hluav taws xob, kev sib haum xeeb thiab kev txhim kho lub zog.Nws hloov cov kev tswj ib txwm siv los ntawm kev txawj ntse reactive zog them nyiaj.Nws yog cov khoom siv hluav taws xob reactive uas muaj cov khoom siv xws li hluav taws xob hluav taws xob, fuses, hloov hloov pauv, lim reactors thiab lub hwj chim capacitors.
Anti-harmonic smart power capacitors yog tsim los rau cov ntaub ntawv uas cov ntsiab lus sib haum xeeb ntawm lub zog hluav taws xob muaj siab thiab cov pa ntse ntse capacitors tsis tuaj yeem ua haujlwm ib txwm.cuam tshuam thiab txhim kho qhov zoo ntawm kev siv hluav taws xob.
