Kev sib koom tes ntawm cov tswv yim tswj:
Hauv lub zog hluav taws xob, muaj kev sib txuas sib txuas ntawm lub zog ua haujlwm thiab lub zog reactive, thiab kev ua haujlwm sib cais ntawm AGC thiab AVC yuav cuam tshuam rau ib leeg kev tswj hwm. Yog li ntawd, ib qho kev tswj xyuas kev tswj hwm ntawm AGC thiab AVC txuas nrog ntawm qhov ntsuas feeb thiab zaum thib ob tau npaj tseg.
Nyob rau theem feeb, tus qauv zoo tshaj plaws ntawm lub zog ntws tau tsim los uas txuas lub zog ua haujlwm thiab lub zog rov ua haujlwm ua ke, thiab kev sib koom ua kom zoo tshaj plaws ntawm AGC thiab AVC tau thov.
Nyob rau theem thib ob, cov tswv yim tswj hwm ntawm AGC thiab AVC tau raug txhim kho, thiab kev sib koom ua ke kev tswj hwm kev tswj hwm rau AGC thiab AVC tau raug npaj.
Kev saib xyuas lub sijhawm tiag tiag thiab teb sai:
Lub AVC system yuav tsis tu ncua saib xyuas qhov voltage ntawm txhua qhov ntawm daim phiaj hluav taws xob thiab muab cov lus qhia ceev nrooj los kho qhov excitation system ntawm lub tshuab hluav taws xob tau teeb tsa thaum qhov hluav taws xob sib txawv ntawm qhov teeb tsa tau pom, txhawm rau kho qhov hluav taws xob mus rau qhov qub.
AGC system tau hloov kho lub tshuab hluav taws xob tso zis raws li lub zog hluav taws xob zaus ntsuas los ntawm cov sensors, tswj xyuas qhov zaus ntawm lub zog hluav taws xob nyob rau hauv qhov tsim nyog.
Kev sau cov ntaub ntawv thiab kev qhia ua haujlwm:
Lub photovoltaic AGC / AVC pab pawg tswj thiab hloov kho lub davhlau ya nyob twg txhawb cov chaw taws teeb hloov ua haujlwm, uas tau txais cov lus qhia hloov chaw nres tsheb loj thiab decomposes lawv rau kev tua rau txhua lub inverter. Paub qhov upload ntawm cov ntaub ntawv xws li tag nrho cov nquag nquag thiab reactive zog, siab tshaj plaws adjustable ntau yam, thiab tus naj npawb ntawm inverters; Txhawb kev txheeb xyuas cov lus qhia los ntawm DMS; Raws li kev ua haujlwm ntawm qhov chaw inverters, decompose lub hom phiaj qhov tseem ceeb rau hauv qhov kev hloov pauv ntawm txhua lub inverter raws li cov cai; Thiab kho txhua lub inverter raws li cov lus qhia decomposed.
Los ntawm txoj kev sib koom tes no, AGC thiab AVC systems ua ke tswj kev ruaj ntseg ntawm lub zog. AGC tswj qhov "rhythm" ntawm zaus, thaum AVC ua kom lub suab nrov ntawm voltage. Ob qho tib si ntxiv rau ib leeg thiab yog qhov tseem ceeb.
Photovoltaic inverters ua lub luag haujlwm tseem ceeb hauv AGC (Automatic Generation Control) thiab AVC (Automatic Voltage Control) systems, raws li hauv qab no:
Kev tswj fais fab:
Nyob rau hauv AGC system, lub photovoltaic inverter yog lub luag hauj lwm rau kev tswj cov zis fais fab ntawm lub photovoltaic array kom muaj nuj nqis nrog rau daim phiaj xav tau. Vim muaj kev hloov pauv hauv hnub ci hluav taws xob thiab huab cua, cov zis hluav taws xob ntawm photovoltaic fais fab tuag yuav hloov pauv. AGC system tswj hwm lub zog hluav taws xob photovoltaic los ntawm kev tswj cov zis hluav taws xob ntawm lub inverter kom muaj kev ruaj ntseg ntawm daim phiaj hluav taws xob.
Reactive zog tswj:
Nyob rau hauv AVC system, photovoltaic inverters yog siv los tswj cov qib voltage ntawm daim phiaj hluav taws xob, kom ntseeg tau qhov zoo ntawm cov khoom siv hluav taws xob thiab kev ua haujlwm zoo ntawm cov khoom siv. Kev sib koom ua ke ntawm cov tshuab hluav taws xob photovoltaic yuav muaj kev cuam tshuam rau qhov hluav taws xob ntawm daim phiaj hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas muaj kev hloov loj hauv cov teeb pom kev zoo. AVC system kho cov kab hluav taws xob hluav taws xob los ntawm kev tswj cov hluav taws xob reactive tawm ntawm lub inverter.
Maximum Power Point Tracking (MPPT):
Photovoltaic inverters muaj qhov siab tshaj plaws lub zog taw tes nrhiav kev ua haujlwm, uas tuaj yeem ua tiav lub zog siab tshaj plaws ntawm cov hnub ci vaj huam sib luag los ntawm kev hloov cov load impedance, yog li txhim kho lub zog tsim efficiency ntawm photovoltaic systems.
Daim phiaj tiv thaiv muaj nuj nqi:
Photovoltaic inverters kuj muaj ntau yam kev tiv thaiv kev ua haujlwm, xws li kev tiv thaiv kev tiv thaiv, kev tiv thaiv overload, kev tiv thaiv hauv av, thiab lwm yam., kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm photovoltaic fais fab nroj tsuag.
Teb rau AGC cov lus qhia:
Thaum AGC tus tswv tsev tau txais qhov tsis sib haum xeeb ntawm tus nqi tam sim no lub hwj chim phiaj xwm thiab cov zis tam sim no ntawm lub chaw nres tsheb photovoltaic, nws yuav muab cov lus qhia rau lub inverter, thiab lub inverter yuav kho cov zis hluav taws xob raws li cov lus qhia no kom ua tiav qhov kev hloov pauv ntawm lub zog. zog.
Reactive zog tswj muaj peev xwm:
Nyob rau hauv cov xwm txheej tsis tu ncua ntawm daim phiaj hluav taws xob, AVC tus tswv yuav siv tag nrho cov kev tswj xyuas hluav taws xob muaj peev xwm ntawm lub inverter los tswj qhov voltage. Thaum lub reactive hwj chim tswj muaj peev xwm ntawm lub inverter yog tsis txaus, lub reactive hwj chim tswj ntawm lub SVC / SVG ntaus ntawv yuav raug txiav txim.
Kev sib koom tes thiab kev tswj hwm:
Nyob rau hauv qhov kev tshwm sim ntawm lub hwj chim tsis ua hauj lwm, tus tswv tsev AVC sai kho lub reactive hwj chim ntawm lub SVC / SVG ntaus ntawv los kho qhov voltage mus rau ib txwm theem. Tom qab daim phiaj hluav taws xob rov qab los ntawm qhov txhaum, AVC tus tswv tuaj yeem hloov lub zog reactive uas twb tau muab tso rau hauv kev ua haujlwm los ntawm kev kho cov hluav taws xob reactive tawm ntawm lub inverter, tso cai rau nws los khaws cov khoom tsim nyog dynamic reactive zog cia.
