Imvelaphi yeProjekthi
I-Wuzhong Intercity Railway yinxalenye ebalulekileyo ye "Jinglan Corridor" kuthungelwano lwesizwe "lwasibhozo oluthe nkqo kunye nesibhozo oluthe tyaba" oluhamba ngesantya esiphezulu.Le projekthi iqala kwisiXeko saseWuzhong emantla kwaye ihamba ecaleni kweBeijing-Tibet Expressway emazantsi, idlula kwiLake laseGuanma, imithombo eqengqelekayo, kwaye inqumla indawo enenduli yeNtaba yeNiushou.Isikhululo saseZhongning East siza kusekwa eZhongning County, kwaye iSikhululo saseZhongwei saseMazantsi siza kusekwa ngasentshona ecaleni komlambo osemazantsi woMlambo oMthubi udlula eXuanhe ukuya kwisiXeko saseZhongwei.Umgca wonke uneSikhululo saseMantla saseHongsibao, iSikhululo saseZhongning East, iSikhululo saseZhongwei esiMazantsi, isiKhululo saseGuanmahu esigciniweyo kunye neSikhululo saseXuanhe saseMzantsi.Le projekthi iqhagamshelwe kwiSikhululo saseWuzhong seYinxi High-speed Railway emantla, kwaye idibanisa iLingwu, iHedong Airport kunye neYinchuan ecaleni kweYinxi Line ukuya emantla.Inokufikelela eShahu, eShizuishan, naseHuinong ngeBaolan Line kunye neBaoyin High-speed Railway esakhiwayo.Ngaphantsi kokwakhiwa, iLankezhuan inokufikelela eBaiyin naseLanzhou;emazantsi ngeBaozhong Line, inokufikelela kwisiXeko saseGuyuan kunye neNdawo yeLiupanshan ebukekayo.
Usetyenziso
Le projekthi ithatha iimveliso zenkampani yethu ezisebenzayo zokucoca, kubandakanywa iimodyuli zokucoca ezisebenzayo, njl. Ezisetyenziswa ikakhulu kulawulo lwe-harmonic kunye nembuyekezo yamandla asebenzayo.Ukucoca ngokufanelekileyo ii-harmonics, qinisekisa ukusebenza okuzinzileyo nokuthembekileyo kwezixhobo zamandla, kunye nokukhapha igridi yamandla aluhlaza.
Iinzuzo zemveliso yokucoca esebenzayo
1. Imbuyekezo ye-Harmonic: I-APF inokucoca i-2 ~ 50 i-harmonics ngexesha elifanayo
2. Imbuyekezo yamandla asebenzayo: ubuntununtunu be-capacitive (-1~ 1) imbuyekezo engenanyathelo
3. Impendulo ekhawulezayo kakhulu, ulawulo olukhawulezileyo
4. Ubomi boyilo bungaphezulu kweeyure ezingama-100,000 (ngaphezu kweminyaka elishumi)
Isihlungi esisebenzayo se-HYAPF sibona umthwalo wangoku ngexesha langempela ngokusebenzisa i-CT ye-transformer yangaphandle, kwaye ibala nge-DSP yangaphakathi ukukhupha amacandelo e-harmonic yomthwalo wangoku, kwaye emva koko ithumela isibonakaliso se-PWM kwi-IGBT yangaphakathi ukulawula i-inverter ukuvelisa. inxalenye ye-harmonic yomthwalo.I-currents enamaza alinganayo kunye nezalathiso ezichaseneyo zifakwe kwigridi yamandla ukuhlawulela i-harmonic currents ukuphumeza ukuhluza.
