Kev tshuaj xyuas ntawm Internal Structure ntawm Reactive Power Compensation Controllers
Dec 01, 2025| Hauv cov tshuab hluav taws xob niaj hnub no, cov khoom siv hluav taws xob reactive zog, raws li cov cuab yeej tseem ceeb, tau dav siv los txhim kho kev ua tau zoo thiab ruaj khov ntawm lub zog hluav taws xob.
I. Internal Structure of Reactive Power Compensation Controllers
Lub internal qauv ntawmreactive zog them nyiaj controllersfeem ntau suav nrog cov ntsiab lus tseem ceeb hauv qab no:
1. Sensor Module
Lub sensor module yog lub luag haujlwm rau kev saib xyuas lub sijhawm tiag tiag ntawm daim phiaj xwm txheej xws li voltage, tam sim no, thiab lub zog. Cov sensors no xa cov ntaub ntawv mus rau tus maub los lub khoos phis tawj rau kev txheeb xyuas thiab ua tiav tom qab. Qhov raug thiab teb ceev ntawm cov sensors ncaj qha cuam tshuam rau tus tswj kev ua haujlwm.
2. Chav ntsuas
Lub khoos phis tawj ua haujlwm ua lub hlwb ntawm lub zog reactive zog them nyiaj tswj. Nws lub luag haujlwm tseem ceeb yog txhawm rau txheeb xyuas thiab suav cov ntaub ntawv khaws tseg. Nws feem ntau yog tsim los ntawm microprocessor lossis digital signal processor (DSP), muaj peev xwm ua tiav cov ntaub ntawv ntau sai thiab suav cov nyiaj them rov qab uas yuav tsum tau ua raws li kev tswj hwm algorithms. Kev suav lub zog ntawm lub khoos phis tawj thiab qib kev ua kom zoo ntawm cov algorithms txiav txim siab tus tswj cov lus teb ceev thiab tswj qhov tseeb.
3. Tswj Module
Tus tswj module ua haujlwm cov khoom siv hluav taws xob rov ua haujlwm raws li cov lus txib los ntawm lub tshuab xam phaj, xws li hloov cov capacitors lossis kho cov excitation tam sim no ntawm synchronous motors. Tus tswj module yuav tsum muaj cov lus teb sai thiab muaj kev ntseeg siab kom ntseeg tau tias daim phiaj ruaj khov nyob rau hauv cov xwm txheej zoo.
4. Kev sib txuas lus interface
Niaj hnub nimno reactive fais fab kev them nyiaj controllers feem ntau nruab nrog ntau yam kev sib txuas lus interfaces, xws li RS-232, RS-485, thiab Ethernet. Cov interfaces no yog siv rau kev sib pauv ntaub ntawv nrog rau lwm yam khoom siv lossis tshuab. Los ntawm cov kev sib cuam tshuam no, tus neeg siv hluav taws xob them nyiaj rov qab tuaj yeem txuas nrog lub tshuab hluav taws xob substation automation, chaw saib xyuas tej thaj chaw deb, thiab lwm yam, ua kom muaj kev saib xyuas thiab kev ua haujlwm.
5. Tib neeg-Machine Interface
Tib neeg-Machine Interface (HMI) yog lub qhov rais rau cov neeg siv kev sib cuam tshuam nrog tus maub los, feem ntau suav nrog lub vijtsam zaub, nyees khawm, thiab qhov taw qhia teeb. Los ntawm HMI, cov neeg ua haujlwm tau yooj yim saib cov xwm txheej tam sim no, cov ntaub ntawv tswj xyuas kev ua haujlwm, thiab ua kom muaj feem cuam tshuam thiab hloov kho. Ib qhov zoo -HMI tsim tsis tsuas yog txhim kho cov neeg siv kev paub tab sis kuj txhim kho kev ua haujlwm yooj yim.
