PV System Automatic Reactive Compensation Controller

Jinneng hluav taws xob photovoltaic PV system tsis siv neeg reactive them nyiaj tswj yog tshwj xeeb tsim los rau kev tswj tsis siv neeg thiab tswj cov hluav taws xob reactive nyob rau hauv 400V daim phiaj- txuas PV systems. Cov maub los no suav nrog cov kev ua kom zoo tshaj plaws los daws cov teeb meem tshwm sim hauv cov qauv kev them nyiaj ib txwm siv, xws li cov khoom siv hluav taws xob tsis raug thiab hloov cov kev ua haujlwm tsis zoo los ntawm kev tswj cov logic tsis meej pem tom qab PV kev koom ua ke. Leveraging peb lub tuam txhab xyoo ntawm kev txawj ntse nyob rau hauv reactive fais fab nyiaj them technology, nws muab tshwj xeeb stability thiab kev cia siab rau, ua rau nws ib tug indispensable mob siab rau maub los rau PV systems.

 

● Txo cov kab poob thiab txhim kho kev siv cov khoom siv hluav taws xob

● Stabilizes kawg- cov neeg siv hluav taws xob thiab txhim kho cov khoom siv hluav taws xob zoo

● HMI nrog loj LCD zaub, Ntau lub tswb teeb tsa ua haujlwm (tso zis relay lossis suab ceeb toom muaj)

● Txhawb tus tswv- qhev configuration (1 tus tswv + 3 qhev) nrog txog 96 qhov tso tawm circuits, Modular expandability

● RS485 interface nrog MODBUS-RTU, Ua kom muaj kev hloov pauv chaw taws teeb, saib xyuas cov xwm txheej, thiab kev hloov pauv tsis ua haujlwm.

Lus Cim rau Active Output Terminals:

Rau cov khoom siv hluav taws xob nquag, tsuav yog tias tag nrho cov khoom tso tawm tam sim no tsis pub dhau tus naj npawb ntawm circuits multiplied los ntawm 8mA, ib qho hluav taws xob hluav taws xob tau tso cai tawm mus txog 20mA.

Piv txwv li, 24-circuit controller tso cai rau tag nrho cov zis tam sim no ntawm 24 × 8=192mA.

Yog tias tsuas yog siv 10 circuits xwb, txhua qhov hluav taws xob tuaj yeem tawm mus txog 192 / 10=19.2mA.

 

 

● Fais fab mov hom:

Thaum lub kaum sab xis yog nyob rau hauv 1st lossis 4th quadrant, lub load rub lub zog siv los ntawm qhov siab -voltage grid. Qhov no yog hu ua Power Supply Mode.

● Lub Hom Phiaj Tsim:

Thaum lub kaum sab xis yog nyob rau hauv 2nd lossis 3rd quadrant, lub load pub lub zog ua haujlwm rov qab rau hauv siab -voltage grid. Qhov no yog hu ua Power Generation Mode.

● Tsis siv neeg ua haujlwm:

Lub davhlau ya nyob twg tswj tau txiav txim siab txog kev khiav hauj lwm hom (siv / tiam) raws li qhov polarity ntawm lub ntsiab txee lub zog. Nws mam li hloov cov txhab nyiaj capacitor kom tswj tau qhov system fais fab hauv qhov teeb tsa.

● Kev khiav hauj lwm phau ntawv:

Tus maub los hloov lub hwj chim capacitor raws li cov neeg siv cov lus txib. Qhov kev ua haujlwm no feem ntau yog siv rau kev kuaj lub Hoobkas ntawm cov khoom them nyiaj.
