Qhov project Background
Wuzhong Intercity Railway yog ib feem tseem ceeb ntawm "Jinglan Corridor" hauv lub tebchaws "yim ntsug thiab yim kab rov tav" kev tsheb ciav hlau ceev ceev.Qhov project pib los ntawm Wuzhong City nyob rau sab qaum teb thiab khiav raws Beijing-Tibet Expressway nyob rau sab qab teb, hla Guanma Lake, rolling springs, thiab hla lub toj roob hauv pes Niushou.Zhongning East Chaw nres tsheb yuav tsim nyob rau hauv Zhongning County, thiab Zhongwei South Chaw nres tsheb yuav tsum teem rau sab hnub poob raws ntug dej hiav txwv sab qab teb ntawm Xuanhe mus rau Zhongwei City.Tag nrho cov kab muaj Hongsibao North Chaw nres tsheb, Zhongning East Chaw nres tsheb, Zhongwei South Chaw nres tsheb, tseg Guanmahu Chaw nres tsheb thiab Xuanhe South Chaw nres tsheb.Qhov project yog txuas nrog Wuzhong Chaw nres tsheb ntawm Yinxi High-speed Railway nyob rau sab qaum teb, thiab txuas Lingwu, Hedong tshav dav hlau thiab Yinchuan raws Yinxi Kab mus rau sab qaum teb.Nws tuaj yeem ncav cuag Shahu, Shizuishan, thiab Huinong ntawm Baolan Line thiab Baoyin High-speed Railway nyob rau hauv kev tsim kho.Hauv kev tsim kho, Lankezhuan tuaj yeem ncav cuag Baiyin thiab Lanzhou;sab qab teb ntawm Baozhong Kab, nws tuaj yeem mus txog Guyuan City thiab Liupanshan Scenic Area.
Daim ntawv thov
Qhov project no siv peb lub tuam txhab cov khoom siv lim dej series, suav nrog cov lim dej ua haujlwm, thiab lwm yam. Feem ntau yog siv rau kev tswj hwm kev sib raug zoo thiab kev siv hluav taws xob rov ua haujlwm.Ua zoo lim tawm kev sib haum xeeb, ua kom ruaj khov thiab txhim khu kev lag luam ntawm cov khoom siv hluav taws xob, thiab coj mus rau daim phiaj ntsuab ntsuab.
Active lim khoom zoo
1. Harmonic them nyiaj: APF tuaj yeem lim tawm 2 ~ 50 harmonics tib lub sijhawm
2. Reactive fais fab nyiaj them: capacitive rhiab heev (-1 ~ 1) stepless them
3. Cov lus teb ceev heev, kev tswj xyuas tam sim
4. Tsim lub neej yog ntau tshaj 100,000 teev (ntau tshaj kaum xyoo)
Lub HYAPF nquag lim pom cov load tam sim no nyob rau hauv lub sijhawm tiag tiag los ntawm sab nraud tam sim no transformer CT, thiab xam los ntawm lub internal DSP kom rho tawm cov harmonic Cheebtsam ntawm lub load tam sim no, thiab ces xa PWM teeb liab mus rau lub internal IGBT tswj lub inverter los tsim. ib tug harmonic tivthaiv ntawm lub load.Currents nrog sib npaug nthwv dej thiab cov lus qhia rov qab yog txhaj rau hauv daim phiaj hluav taws xob kom them nyiaj rau cov kev sib raug zoo tam sim no kom ua tiav cov lim dej.
