Sab nraum zoov High Voltage Reactive Power Compensation Txee

Jinneng hluav taws xob Sab nraum zoov high voltage reactive fais fab nyiaj them txee yog ib tug sab nraum zoov ncej-mounted reactive fais fab nyiaj them system tsim rau 6-10kV kis tau tus mob kab. Nws cia li kho lub hwj chim capacitive los txhim kho lub zog zoo thiab txo cov kab poob, stabilizes voltage fluctuations.

● Lub txhab nyiaj capacitor, reactor, hloov cov cuab yeej thiab cov cuab yeej tiv thaiv tau muab tso ua ke, nrog rau qhov me me uas yooj yim rau kev teeb tsa.

● Chaw nyob ibteeb meem nyiaj txiag(zog pov tseg thiab nplua) los ntawmtechnical txhais tau tias(supply reactive zog).

● Xa cov txiaj ntsig ntxiv hauvsystem kev ua tau zoo(voltage stability, muaj peev xwm nce) thiabkhoom siv kev nyab xeeb(kev txo qis, txias).

● Kev Nyab Xeeb Capacitor:

Ua tau -hauv fuse + tso tawm resistor (tus kheej- tawm mus<50V within 3 minutes).

Saj zawg zog configuration: Sab hauv / sab nraud capacitors nrog 1: 2 muaj peev xwm piv rau 3-kauj ruam hloov.

● Hloov Logic:

Tsis siv neeg tswj los ntawm voltage, PF, los yog reactive tam sim no.

Txhawb phau ntawv rau kev debugging.

● Kev tiv thaiv:

Tshaj / nyob rau hauv voltage, overcurrent, theem poob, thiab harmonic overload (THD xyuas).

● Nqus Contactor:

Kev tu-dawb, siab- zaus hloov pauv (300k+ cycles).

● Tiag -Tsev Sijhawm Saib Xyuas

Qhia tawm qhov hluav taws xob, tam sim no, active / reactive zog, PF, THD%, thiab harmonics.

● Cov ntaub ntawv kaw lus

Khaws 200+ hnub ntawm cov ntaub ntawv ua haujlwm (txuas ntxiv mus rau 800 hnub).

● Chaw taws teeb tswj

"Four Remote" ua haujlwm: telemetry, tswj, hloov kho, thiab ceeb toom ceeb toom.

● Kev sib txuas lus

Txhawb xaim (RS485) thiab luv-ntau wireless (30–50m rau cov khoom siv tes).

 

 

Reactive Power Compensation Capacity Calculation thiab Configuration Guide

1. Muaj peev xwm xam cov qauv

Hloov pauv:

PLub cev muaj zog (kW)

cos⁡ϕ1 ​​: Lub zog tseem ceeb

cos⁡ϕ2: Lub hom phiaj fais fab (feem ntau yog 0.95)

Txoj Cai Xaiv:

YogP = tsis tu ncua load, xaiv ntau dua cos⁡ϕ2​​(piv txwv li, 0.98)

YogP = ncov load, xaiv qis cos⁡ϕ2​​(piv txwv li, 0.92)

 

2. Lub tswv yim them nyiaj

Kev teeb tsa	Daim ntawv thov Scenario	Capacity Ratio
Kev them nyiaj tas li	- Lub hauv paus reactive thov - Tsawg dua lossis sib npaug li 10% ntawm transformer tsis muaj -Load peev	5-10% ntawm tag nrho kVar
1 Auto-Switched Group	Kev hloov pauv nruab nrab ntawm kev thauj khoom (tsawg dua lossis sib npaug li 30% qhov sib txawv ntawm qhov siab tshaj / tsis tu ncua)	1: 1 (piv txwv li, 100kVar)
2 Auto-Hloov pab pawg	Large load fluctuation (>30% sib txawv)	1:2 (eg, 100+200kVar)

Tus nqi -Txuag Tswv Yim: Txhim kho cov nyiaj them poob haujlwm nyob ze ntawm cov chaw thauj khoom kom tsis txhob overvoltage thaum tsis muaj -load tej yam kev mob.

 

3. Cov cai tswj qhov chaw

Tswj txoj kev	Txoj hauj lwm	Kev xav tau
Reactive Current Control	Kab taub hau	>70% ntawm load tam sim no yuav tsum dhau los ntawm kev kuaj CT
Kev tswj hluav taws xob	Kab kawg (tsawg-voltage nodes)	Overcompensation yuav siv tau; tsis xav tau CT
Txoj Cai	2/3-3/4 ntawm kab ntev	Qhov ze rau qhov chaw thauj khoom minimizes reactive fais fab kis tau los

 

4. Cov lus qhia ua tau

Fixed Compensation Unit:

Xws li: Tso fuse + ntes + capacitor bank

Installation: Downstream ntawm load center

Kev tswj hluav taws xob:

Siv thaum kab -kawg voltage yog<90% of nominal

Overcompensation ib ntus nce voltage (saib xyuas kom tsis txhob ua PF)

 

5. Piv txwv Configuration

Rau 10kV kab nrog:

Tsis tu ncua loadP = 500kW, cos⁡ϕ1​=0.8 → cos⁡ϕ2​=0.95

Kev suav:

Qc=500×(0.75−0.33)=210 kvar

Kev siv:

Tsau: 20kvar (10% ntawm tag nrho)

Pib-Hloov: 100kvar + 90kvar (1:0.9 piv)
