Yuav Ua Li Cas Nrog Harmonic Amplification Tom Qab Kev Ua Haujlwm ntawm Solar Power Generation Systems

1. Qhov tseem ceeb ntawm Harmonic Amplification nyob rau hauv Solar Power Generation Systems

1) Tsis yog - tawm tawm tawm ntawm inverters

Lub hnub ci hluav taws xob tsim hluav taws xob tso siab rau inverters los hloov DC lub zog rau hauv AC zog. Thaum lub sij hawm siab -kev hloov pauv ceev ntawm inverters, ib qho kev faib ua feem ntawm siab - zaus harmonic Cheebtsam yuav raug tsim. Thaum ntau lub hnub ci hluav taws xob tsim hluav taws xob txuas nrog hauv kev sib xyaw ua ke, cov kev sib haum xeeb tam sim no yuav raug superimposed thiab amplified.

2) Resonance tshwm sim los ntawm qhov system impedance variation

Tom qab daim phiaj sib txuas ntawm lub hnub ci hluav taws xob tsim hluav taws xob, cov qauv hluav taws xob ntawm daim phiaj impedance yuav raug hloov. Yog tias cov khoom siv hluav taws xob rov ua haujlwm lossis cov tsev txhab nyiaj capacitor muaj nyob rau ntawm qhov chaw, cov ntsiab lus tshiab resonant zaus yuav raug tsim, yog li nthuav qhia tshwj xeeb - xaj harmonics.

2. Kev phom sij ntawm Harmonic Amplification nyob rau hauv Solar Power Generation Systems

1) Kev kub siab nce ntawm cov khoom siv hluav taws xob

Harmonic tam sim no yuav ua rau kom cov kab poob thiab ua kom cov cua sov ntawm transformers, cables thiab them capacitors. Ntev- lub sijhawm ua haujlwm ntawm lub hnub ci hluav taws xob tsim hluav taws xob nyob rau hauv siab - ib puag ncig kev sib haum xeeb tuaj yeem ua rau lub neej luv ntawm cov khoom siv.

2) Deterioration ntawm lub zog zoo

Thaum lub harmonic distortion tus nqi siab tshaj tus qauv, malfunctions los yog unstable ua hauj lwm tej zaum yuav tshwm sim nyob rau hauv cov khoom rhiab heev. Txawm hais tias lub hnub ci hluav taws xob tsim hluav taws xob txhim kho kev siv hluav taws xob zoo, kev tswj hwm tsis txaus yuav cuam tshuam rau tag nrho cov khoom siv hluav taws xob zoo.

3. Kev daws teeb meem rau Harmonic Amplification hauv Solar Power Generation Systems

1) Txhim kho cov khoom siv lim dej

Rau cov xwm txheej uas muaj kev sib haum xeeb siab,Active fais fab lim (APF)tuaj yeem ntsia tau rau ntawm daim phiaj sib txuas ntawm lub hnub ci hluav taws xob tsim hluav taws xob. Cov cuab yeej no tuaj yeem txheeb xyuas cov khoom sib haum xeeb hauv lub sijhawm tiag tiag thiab tso tawm cov nyiaj rov qab them nyiaj tam sim no kom txo tau qhov cuam tshuam zoo.

2) Optimization ntawm reactive zog them nyiaj configuration

Yog hais tias lub hauv paus system yog nruab nrog lub tsev txhab nyiaj capacitor, cov nyiaj them poob haujlwm thiab tus nqi reactance yuav tsum rov ua dua - soj ntsuam.Series reactorslos yog kho cov phiaj xwm kev them nyiaj tuaj yeem raug coj los ua kom tsis txhob muaj kev cuam tshuam ntawm lub hnub ci hluav taws xob tsim hluav taws xob thiab cov capacitors.

3) Kev tsom xam ntawm kab hluav taws xob- sib txuas muaj peev xwm thiab teeb tsa

Hauv cov chaw ua si loj lossis cov haujlwm hauv nruab nrab ntawm photovoltaic, daim phiaj - txuas peev xwm thiab nkag mus rau qhov chaw ntawm lub hnub ci hluav taws xob tsim hluav taws xob yuav tsum tau npaj kom tsim nyog. Zam kev nkag mus rau hauv nruab nrab ntawm ntau yam khoom siv rau tib lub node pab txo qhov kev pheej hmoo ntawm kev sib haum xeeb superposition.
