Ntau tus neeg tsim lub hnub ci tus kheej- kev siv hluav taws xob nug tib lo lus nug: yog tias koj tsis muag hluav taws xob rov qab rau hauv kab hluav taws xob, vim li cas thiaj nruab ib lub zog tiv thaiv rov qab? Raws li lub tuam txhab tsom mus rau kev saib xyuas lub zog zoo, peb xav rhuav tshem qhov no los ntawm peb lub kaum ntse ntse - kev nyab xeeb daim phiaj, kev tiv thaiv cov cuab yeej, thiab kev ua raws cai- yog li cov laj thawj pom tseeb.

Txoj cai tseem ceeb ntawm tus kheej - kev noj haus yog qhov yooj yim: ntawm qhov kev sib tshuam, lub zog yuav tsum tsis txhob ntws rov qab mus rau hauv daim phiaj. Kev tiv thaiv hluav taws xob thim rov qab tswj hwm txoj cai nrog kho vajtse- tswj qib. Tam sim no cov sensors saib xyuas lub rooj vag fais fab hauv lub sijhawm tiag tiag, thiab qhov tam sim no lawv pom qhov sib txawv ntawm qhov rov qab ntws, tus maub los yog curtails lub inverter tso zis los yog disconnects khi nyob rau hauv kaum ntawm milliseconds. Lub kaw lus raug yuam kom tsuas yog kos los ntawm kab sib chaws, tsis txhob xa tawm mus rau nws. Ntxiv qhov kev tiv thaiv no tsis yog tus nqi ntxiv -nws yog txoj hauv kev pheej yig tshaj kom tsis txhob muaj kev pheej hmoo uas yuav luag tshwm sim.

 

Kev nyab xeeb rau tib neeg thiab kab sib chaws yog qhov laj thawj tseem ceeb tshaj plaws. Thaum cov khoom siv hluav taws xob tuag rau kev saib xyuas lossis vim muaj kev ua txhaum, PV system tsis muaj kev tiv thaiv hluav taws xob rov qab tuaj yeem txuas ntxiv tsim thiab txhawb nqa cov de- cov kab hluav taws xob, tsim kom muaj cov kob uas tsis txhob txwm ua. Qhov ntawd tso cov hluav taws xob txaus ntshai rau cov neeg siv hluav taws xob uas cov neeg ua haujlwm kab xav tias yuav tuag - qhov ua yuam kev ua rau tuag taus. Thiab thaum daim phiaj hluav taws xob rov qab los, qhov hluav taws xob theem tsis sib haum xeeb ntawm cov kab ke thiab cov kab sib chaws tuaj yeem ua rau muaj kev cuam tshuam loj heev tam sim no muaj peev xwm ua rau puas tsuaj rau cov transformers, inverter, thiab lwm yam khoom siv ntawm tib lub voj voog. Kev sib txuas cov qauv zoo li IEEE 1547 thiab IEC 62116 kho kev tiv thaiv -Islanding thiab thim rov qab kev tiv thaiv hluav taws xob raws li qhov yuav tsum tau ua. Yog tsis muaj nws, ib qho kev siv tus kheej - tsuas yog yuav tsis dhau kev ua haujlwm.

Lub zog thim rov qab kuj tseem cuam tshuam ncaj qha rau koj cov khoom thauj thiab ua rau lub zog tsis zoo. Thaum lub hnub ci hluav taws xob thawb mus rau hauv kab sib chaws, kab impedance ua rau qhov hluav taws xob ntawm qhov chaw sib txuas nce. Sustained overvoltage accelerates aging nyob rau hauv LED tsav tsheb, lub cev muaj zog windings, thiab hloov - hom fais fab mov - tsis muaj dab tsi zoo li tsis ncaj ncees lawm thaum xub thawj, tab sis lub neej poob qis heev. Txawm hais tias ib qho hluav taws xob qis qis feem ntau ua rau lub inverter rov ua dua qhov kev mus ncig dhau los thiab kev sib txuas, yog li cov khoom tsim tawm tau poob qis dua li nce. Lub zog rov qab relay clamps lub rooj vag fais fab ntawm xoom lossis ib qho zoo me me, suppressing qhov txawv txav ntawm nws qhov chaw.

 

Tom qab ntawd muaj qhov cuam tshuam rau tag nrho lub zog zoo thiab daim phiaj sib raug zoo. Uncontrolled reverse flows tsim voltage fluctuations, flicker, thiab phem harmonic pa phem. Thaum ntau tus kheej -siv tshuab sib koom ua ke sib faib transformer, sib cuam tshuam rov qab fais fab stacking tau yooj yim thawb tag nrho cov kev sib haum xeeb voltage distortion yav dhau los 8%, deb tshaj li 5% txwv tau pom zoo los ntawm IEEE 519. High- txiav txim harmonics kuj ua rau cov nruab nrab tam sim no ntau dhau, tsis zoo transformer cua sov, thiab ceev rwb thaiv tsev aging. Peb tau ua sab -los ntawm- sab teb kev ntsuas nrog cov khoom siv hluav taws xob zoo ntsuas hluav taws xob ntawm tib qhov kev sib txuas: nrog kev tiv thaiv hluav taws xob rov qab koom nrog, flicker thiab harmonic qib poob los ntawm qhov kev txiav txim loj. Tsuas yog kev tswj fais fab rov qab zoo xwb, ua ke nrog lub nrawm- teb inverter, tuaj yeem kaw lub zog zoo ntawm daim phiaj sib txuas hauv qhov tso cai. Rau cov chaw uas muaj ntau yam khoom siv rhiab heev, peb mus ntxiv thiab pom zoo kom muaj lub zog hluav taws xob zoo hauv online uas txuas txuas txuas lub rooj vag fais fab. Yog tias pom qhov rov qab pub mis, nws ua rau muaj kev tiv thaiv tam sim, kaw lub voj tswj lub sijhawm.

Metering thiab tswj kev pheej hmoo yuav tsis raug ignored ib yam. Feem ntau cov kev siv hluav taws xob nruj me ntsis txwv tsis pub rov qab pub mis. Ib tug qub electromechanical meter yuav tig rov qab; lub ntsuas hluav taws xob ntse yuav tsim qhov yuam kev rov qab - cov nqi hluav taws xob. Hloov chaw kom tau txais qhab nia, tus neeg siv tuaj yeem ntsib kev nplua lossis txawm tias kev pabcuam cuam tshuam. Nrog kev tiv thaiv hluav taws xob rov qab rau hauv qhov chaw, lub qhov rooj ntsuas qhov ntsuas yuav nyob twj ywm huv thiab unidirectional -txhua lub zog ntws tawm tuaj, thiab cov kev tsis sib haum xeeb tsuas tsis tshwm sim.

 

Ib qho ntxiv yuav tsum tau qhia meej: qhov kev tiv thaiv -Islanding feature ua rau hauv lub inverter tsuas yog teb rau cov kab hluav taws xob ua tiav. Nws tsis tuaj yeem tuav lub zog thim rov qab los ntawm kev hloov pauv sai thaum lub phiaj xwm tseem muaj zog. Kev ua tiav qhov tseeb xoom xa tawm yog nyob ntawm qhov siab - qhov tseeb lub zog ntsuas hluav taws xob thiab tus tswj ceev ceev. Peb lub zog ntsuas hluav taws xob zoo sib xyaw ua ke nrog kev tswj fais fab rov qab los siv millisecond -theem fais fab kev taw qhia logic, nquag ntes cov nthwv dej thiab lub sijhawm ntawm cov xwm txheej thim rov qab. Qhov ntawd muab cov ntaub ntawv nyuaj rau installers los ua pov thawj tias lub kaw lus ua tau raws li cov qauv kev sib txuas.

Hauv luv luv, kev tiv thaiv hluav taws xob thim rov qab hauv lub hnub ci tus kheej- kev siv hluav taws xob tsis yog xaiv tau- nws yog qhov yuav tsum tau cawm txoj sia los ntawm daim phiaj, thiab tag nrho - spectrum tiv thaiv rau cov neeg ua haujlwm kev nyab xeeb, cov cuab yeej siv tau ntev, lub zog zoo, thiab kev ua raws li kev them nqi. Tsuas yog thaum qhov kev tiv thaiv no ua tau zoo tuaj yeem ua rau PV system ua haujlwm nyab xeeb, ua tau zoo, thiab tsis saib rov qab.
