Cov txheej txheem ua tiav ntawm siab -voltage reactive fais fab nyiaj them cov cuab yeej yog cov cuab yeej tseem ceeb siv hauv 6kV ~ 35kV lub zog hluav taws xob. Nws ua tiav dynamic reactive fais fab nyiaj them los ntawm parallel capacitor banks thiab ntse tswj systems. Nws lub luag haujlwm tseem ceeb suav nrog:
Kev txhim kho lub zog muaj zog: Kev them nyiaj rau lub zog reactive thov ntawm inductive loads kom ruaj khov lub zog tshaj 0.95
Voltage stability: suppress voltage fluctuations thiab tswj lub fluctuation amplitude nyob rau hauv ± 2%
Harmonic tswj: Los ntawm kev siv cov reactors series (reactance tus nqi ntawm 4% ~ 12%) los suppress 5-7 harmonics, qhov harmonic distortion tus nqi yuav raug txo kom qis dua 3.5%.
Main circuit Cheebtsam
High voltage parallel capacitor bank: txais tag nrho cov zaj duab xis los yog zaj duab xis daim ntawv sib xyaw qauv, nrog hloov tau yooj yim pab pawg (muaj peev xwm sib npaug / tsis muaj peev xwm)
Series reactor: H-qib tooj liab hlau winding, suppresses kaw inrush tam sim no (limiting yam tsawg dua los yog sib npaug rau 2)
Lub tshuab nqus tsev contactor/circuit breaker: tsis muaj kev hloov pauv, nrog lub neej ntev txog 100000 zaug
.
Tswj qhov system
Voltage thiab reactive power integrated controller: txhawb RS485 kev sib txuas lus thiab paub txog "plaub qhov chaw taws teeb" muaj nuj nqi
Kev tiv thaiv chav tsev: nruab nrog ntau yam kev tiv thaiv xws li PT disconnection, overvoltage, thiab capacitor overcurrent
Daim ntawv thov scenarios
Tshiab zog noj: smoothing cua/photovoltaic zog hloov
Kev lag luam hnyav: daws qhov teeb meem ntawm peb -theem imbalance nyob rau hauv hluav taws xob arc furnaces (txo tsis zoo raws li tam sim no los ntawm 15% mus rau 3%)
Substation: Txo cov kab poob los ntawm kev hloov pauv, nrog lub zog ib txwm muaj -txuag tus nqi ntawm 8% ~ 15%
