Kev tivthaiv-qib ceev kaw plc tswj lub thawv yog ib qho kev koom tes nrog kev sib koom ua ke Qhov kev cai lij choj tshwj xeeb yuav tsum tau hais tias lub photovoltaic ntawm txhua lub tsev, thiab lub puab tsaig dhau ntawm 1 lub tsev (305 hli) los ntawm 30 vib nas this tom qab kev kaw sai sai; Lub Circuit Court nyob rau hauv 1 ko taw (305 hli) los ntawm PV module array yuav tsum poob qis dua 80v hauv 30 vib nas this tom qab kaw ceev. Lub Circuit Court nyob rau hauv 1 ko taw (305 hli) los ntawm PV module array yuav tsum poob qis dua 80v hauv 30 vib nas this tom qab kaw sai sai pib.
Cheebtsam tivthaiv-qib hluav taws kub kaw hluav taws xob tsis siv neeg lub zog thiab cov haujlwm rov ua haujlwm. Ntawm lub hauv paus ntawm lub rooj sib tham cov haujlwm kaw sai Thaum lub zog tseem ceeb yog ib txwm thiab tsis muaj xwm txheej tsis muaj xwm txheej Plc tswj lub thawv ceev los txuas rau txhua tus photovoltaic; Thaum lub zog loj tau txiav tawm lossis qhov chaw tiv thaiv thaum muaj xwm ceev, txheej txheem-qib sai sai los ntawm lub bhotovoltaic lub zog kom disconnect txhua tus photuavoltaic.

Ib qho kev tivthaiv-qib kev kaw nrawm plc yog ib qho cuab yeej siv hauv photovoltaic (PV) kom yooj yim kaw cov haujlwm ntawm qib tiv thaiv. Kev kaw nrawm yog qhov yuav tsum muaj kev nyab xeeb rau kev txo qis kev pheej hmoo ntawm cov xwm txheej hluav taws xob thaum muaj xwm txheej ceev lossis txij nkawm.

Nov yog qee cov ntsiab lus tseem ceeb txog kev sib koom ua ke-qib kev kaw nrawm plc tswj lub thawv:

Lub Hom Phiaj: Lub hom phiaj tseem ceeb ntawm kev sib koom ua ke-qib kaw plc tswj Plc tswj lub thawv yog kom ua haujlwm sai sai hauv PV system. Kev kaw nrawm nrawm yog hais txog kev muaj peev xwm sai sai DC cov voj voog ntawm PV system, txo qhov hluav taws xob rau cov neeg muaj kev nyab xeeb thaum muaj kev nyab xeeb.

Plc (programmable logic maub los): A PLC yog lub computer digital siv los tswj thiab siv ntau yam txheej txheem. Nyob rau hauv cov ntsiab lus ntawm lub thawv kaw nrawm, A plc tau ua haujlwm los saib xyuas thiab tswj lub zog kom ceev ntawm PV system. Nws tau txais cov cim los ntawm cov cuab yeej sab nraud thiab pib cov txheej txheem kaw.

Tswj lub npov: lub npov tswj muaj cov khoom siv hluav taws xob tsim nyog, thiab cuam tshuam rau kev siv cov haujlwm kom ceev ceev. Nws feem ntau suav nrog kev txais cov cim los ntawm cov khoom siv sab nraud lossis cov kev kaw sai sai, thiab tawm kom tswj tau cov kev kaw ntawm PV system.

Cov txheej txheem-qib kaw: ib qho kev sib koom ua ke-qib kaw hluav taws xob cuam tshuam nrog kev kaw ntawm PV system, ntau dua li kaw tag nrho cov kab ke. Qhov no tso cai rau cov neeg ua haujlwm thaum muaj xwm ceev los ua haujlwm kom muaj kev nyab xeeb ntawm cov cheeb tsam tshwj xeeb yam tsis muaj kev nthuav dav dav dav.

Kev ua raws li cov cim thiab cov qauv: kaw nrawm tau teev nyob rau hauv cov hluav taws xob cov lej thiab cov qauv, xws li lub teb hluav taws xob hauv tebchaws Asmeskas. Ib feem tivthaiv-qib kev kaw nrawm dua Plc tswj hwm cov cai no kom ntseeg tau tias yuav tsum muaj kev nyab xeeb rau kev nyab xeeb.

Kev sib xyaw: kev tivthaiv-qib kev kaw nrawm plc tswj hwm rau hauv tag nrho PV system tswj thiab tshuaj xyuas cov cuab yeej. Nws sib txuas lus nrog lwm cov txheej txheem system, xws li inverters lossis tshuaj xyuas lub tshuab, los tswj cov txheej txheem kaw sai.

Nws yog ib qho tseem ceeb uas yuav tau sab laj nrog tus tsim nyog siv hluav taws xob tsim nyog lossis PV txheej txheem xaiv, kev sib xyaw ua ke ntawm ib qho kev kawm-qib saiht shc tswj lub thawv. Ua raws li cov cim hluav taws xob hauv zos thiab cov cai yuav tsum tau ua raws li kev nyab xeeb thiab kev ntseeg tau ntawm PV system.
