Piav Qhia luv luv Lub luag haujlwm ntawm Photovoltaic Inverters hauv Hnub Ci Photovoltaic Fais Fab Tsim Tshuab
May 23, 2024
Lub photovoltaic (PV) inverter plays lub luag haujlwm tseem ceeb hauv lub hnub ci photovoltaic lub zog tsim hluav taws xob los ntawm kev hloov hluav taws xob ncaj qha (DC) rau hauv hluav taws xob tam sim no (AC) hluav taws xob. Thaum lub hnub ci vaj huam sib luag tsim hluav taws xob DC nyob rau hauv tshav ntuj, thiab cov roj teeb khaws DC lub zog, ntau yam khoom siv hauv tsev xws li teeb fluorescent, TV, tub yees, thiab kiv cua xav tau AC fais fab. Yog li, txhawm rau ua kom muaj kev siv dav dav ntawm lub hnub ci zog hauv lub neej niaj hnub, inverters uas tuaj yeem hloov DC rau AC lub zog yog qhov tseem ceeb.
Raws li qhov tseem ceeb ntawm PV systems, PV inverter lub luag haujlwm tseem ceeb yog hloov DC hluav taws xob tsim los ntawm hnub ci vaj huam sib luag rau hauv AC hluav taws xob. Ntxiv rau DC-AC hloov dua siab tshiab, inverters kuj ua kom lub hnub ci vaj huam sib luag ua tau zoo thiab muaj kev tiv thaiv kev ua txhaum. Hauv qab no, peb luv luv qhia txog kev ua haujlwm tsis siv neeg thiab kaw cov yam ntxwv ntawm PV inverters, nrog rau lawv qhov siab tshaj plaws lub zog taw tes nrhiav (MPPT) tswj kev ua haujlwm.
1. Qhov siab tshaj plaws Power Point Tracking (MPPT) Tswj Kev Ua Haujlwm:
Cov zis ntawm lub hnub ci vaj huam sib luag sib txawv nrog lub hnub ci siv thiab lub vaj huam sib luag kub. Tsis tas li ntawd, cov hnub ci vaj huam sib luag nthuav tawm qhov hluav taws xob poob raws li qhov tam sim no nce, ua rau qhov chaw ua haujlwm zoo tshaj plaws rau kev tsim hluav taws xob ntau tshaj plaws. Raws li hnub ci hluav taws xob hloov pauv, qhov pom kev ua haujlwm zoo hloov pauv. MPPT tswj xyuas kom ntseeg tau tias lub hnub ci vaj huam sib luag ua haujlwm ntawm lawv qhov chaw siab tshaj plaws, tso cai rau lub kaw lus txuas ntxiv kom tshem tawm cov hluav taws xob ntau tshaj plaws los ntawm lub hnub ci vaj huam sib luag. Qhov no feature yog ib tug yam ntxwv tseem ceeb ntawm inverters siv nyob rau hauv lub hnub ci zog systems.
2. Tsis siv neeg ua haujlwm thiab kaw haujlwm:
Tom qab hnub tuaj, raws li hnub ci hluav taws xob intensifies, cov zis ntawm solar panels nce. Thaum cov zis nce mus txog qib siab zog rau lub inverter ua haujlwm, nws pib ua haujlwm. Thaum ua haujlwm, lub inverter tas li saib xyuas cov zis ntawm cov hnub ci vaj huam sib luag. Ntev npaum li lub hnub ci vaj huam sib luag tso tawm ntau tshaj qhov xav tau lub zog, lub inverter tseem ua haujlwm, txawm tias nyob rau hnub overcast. Thaum lub hnub ci vaj huam sib luag tso zis txo qis thiab zero, lub inverter nkag mus rau hom standby.
Ntxiv rau cov haujlwm uas tau hais los saum no, PV inverters kuj tseem muaj kev tiv thaiv cov Islands tuaj (rau kab sib chaws khi), kev tswj tsis siv neeg hluav taws xob (rau kab sib chaws khi), DC nrhiav pom (rau kab sib chaws khi), thiab DC hauv av nrhiav pom (rau kab sib chaws. - sib txuas systems). Nyob rau hauv lub hnub ci zog systems, qhov ua tau zoo ntawm lub inverter yog ib qho tseem ceeb hauv kev txiav txim siab lub peev xwm ntawm lub hnub ci vaj huam sib luag thiab roj teeb.
