Active Fais Fab Lim rau 2nd-50th Harmonic Mitigation hauv Photovoltaic Fais Fab Chaw
Nov 24, 2025| Thaum lub sij hawm daim phiaj- txuas lub zog tsim hluav taws xob, cov chaw siv hluav taws xob photovoltaic feem ntau ua rau muaj kev sib raug zoo ntawm 2nd mus rau 50th vim kev siv tshuab inverter, ua rau muaj teeb meem tsis zoo. Yog li ntawd, APF (Active Power Filters) tau dhau los ua cov khoom siv zoo tshaj plaws rau ntau lub chaw nres tsheb photovoltaic.
1. Cov teeb meem kev sib haum xeeb hauv cov chaw nres tsheb fais fab photovoltaic
Kev ua haujlwm niaj hnub ntawm photovoltaic fais fab chaw nres tsheb tso siab ntau rau photovoltaic inverters. Txawm li cas los xij, kev siv ntau ntawm cov inverters no tsim 2nd rau 50th harmonics. Cov kev sib raug zoo no tsis yog tsuas yog ua rau cov kab sib chaws thiab cuam tshuam rau lub hwj chim zoo xwb tab sis kuj tuaj yeem ua rau cov khoom siv kub dhau, ua haujlwm tsis zoo, thiab kev puas tsuaj.
2. Txoj Cai Ua Haujlwm ntawm Cov Cuab Yeej Siv Hluav Taws Xob
APF Active Power Filters siv siab - zaus hloov circuits los tsim cov tam sim no nrog tib zaus tab sis cov theem sib txawv raws li cov kev sib haum xeeb, yog li tshem tawm cov khoom sib haum xeeb. Lawv tuaj yeem tsom rau kev sib haum xeeb ntawm qee zaus (xws li 2nd, 5th, thiab 7th) tsim nyob rau hauv photovoltaic fais fab chaw nres tsheb thaum tib lub sijhawm hais txog siab dua -txoj kev sib haum xeeb, xws li 11th, 13th, thiab 17th. Qhov no yog qhov tseem ceeb heev rau daim phiaj{10}}kev sib txuas ntawm cov chaw nres tsheb fais fab photovoltaic.
3. Daim ntawv thov cuam tshuam ntawm Active Fais Fab Lim hauv Photovoltaic Fais Fab Chaw
3.1 Txo ntawm Harmonic Currents
Tom qab txhim kho lub zog lim dej, cov dej sib haum xeeb hauv daim phiaj raug txo qis, tshwj xeeb tshaj yog 2nd mus rau 50th harmonic Cheebtsam, uas yog zoo suppressed. Qhov no tsis tsuas yog daws qhov teeb meem muaj kuab paug nyob hauv cov chaw siv hluav taws xob photovoltaic nkaus xwb tab sis kuj txhim kho daim phiaj kev ruaj ntseg.
3.2 Kev txo qis ntawm daim phiaj hluav taws xob hloov pauv
Nrog rau kev txo qis ntawm kev sib raug zoo ntawm cov pa phem, qhov hloov pauv ntawm qhov hluav taws xob hauv kab sib chaws tau tswj tau zoo, cov khoom siv tsis ua haujlwm raug txo, thiab qhov chaw ua haujlwm rau cov khoom siv hluav taws xob tau txhim kho.
3.3 Kev Txhim Kho ntawm Lub Zog Muaj Zog
Cov lim fais fab tseem tuaj yeem them rov qab rau lub zog reactive, txhim kho lub zog ntawm photovoltaic fais fab chaw nres tsheb. Qhov no txo qis lub nra ntawm lub zog reactive ntawm daim phiaj thiab ntxiv txhim kho daim phiaj kev ua haujlwm zoo.
