- Khoom Taw qhia
Photovoltaic tied Grid Txee (PV Grid-Txuas Txuas Txawb) yog cov khoom siv hluav taws xob tseem ceeb hauv photovoltaic (PV) lub zog tsim hluav taws xob. Nws muaj kev nyab xeeb thiab txhim khu kev qha txuas PV inverters rau hauv daim phiaj, ua kom cov khoom noj - hauv hluav taws xob.
Lub Photovoltaic tied Grid txee ua raws li "choj" ntawm PV chaw nres tsheb fais fab thiab daim phiaj, nrog rau cov haujlwm tseem ceeb hauv qab no:
● Grid Connection Control: Tswj kev sib txuas thiab kev sib txuas ntawm PV system thiab daim phiaj.
● Kev Tiv Thaiv Kev Ua Haujlwm: Tiv thaiv overvoltage, undervoltage, overfrequency, underfrequency, Islanding, thiab lwm yam txawv txav.
● Kev ntsuas hluav taws xob (xaiv tau): Cov ntaub ntawv PV tsim hluav taws xob, daim phiaj pub-hauv, thiab cov neeg siv khoom noj.
● Kev saib xyuas tej thaj chaw deb (Yeem): Txhawb nqa cov ntaub ntawv sau, ceeb toom tsis raug, thiab kev tswj chaw taws teeb.
Nws yog qhov tsim nyog rau thaj chaw faib PV systems, kev lag luam & kev lag luam PV systems, thiab loj - nplai av - mounted fais fab nroj tsuag.
Cheebtsam
Lub Photovoltaic khi Grid Txee feem ntau muaj cov khoom hauv qab no:
