Harmonic yam ntxwv ntawm lub zog faib system hauv chaw nres nkoj thiab wharf kev lag luam

Txhawm rau ua kom tau raws li cov kev xav tau ntawm cov nkoj loj thiab nruab nrab thiab kev lag luam thoob ntiaj teb kev sib koom ua ke, nrog rau cov kev txwv ntawm kev lag luam thiab kev sib raug zoo ntawm cov peev txheej thiab ib puag ncig thiab kev loj hlob ntawm ecological civilization nyob rau hauv ntug hiav txwv ports, kev txhim kho thiab tsim cov dej tob. txoj kev thiab chaw nres tsheb, thiab tsim cov chaw nres nkoj tsheb thauj mus los machinery Loj-scale thiab high-efficiency, cov ntaub ntawv thiab kev tswj kev koom ua ke nyob rau hauv lub chaw nres nkoj kev tswj, systematic kev loj hlob raws li cov yam ntxwv ntawm ntau yam khoom, loj-scale, ntse thiab ecological systems yog cov Qhov tseem ceeb ntawm kev hloov pauv chaw nres nkoj yav tom ntej thiab kev tsim kho tshiab.

Vim tias qhov kev xav tau ntawm kev faib khoom, muaj ntau ntau ntawm aviation crane loads nyob rau hauv kev lag luam thauj khoom xws li cov chaw nres nkoj, thiab cov inverters tau nruab rau ntawm ntau qhov kev thauj khoom.Ib tug loj tus naj npawb ntawm zaus converters zoo heev ua rau kom cov harmonic cov ntsiab lus nyob rau hauv lub hwj chim faib system ntawm qhov chaw nres nkoj kev lag luam.Tam sim no, cov txheej txheem rectification ntawm feem ntau inverters siv rau-pulse rectification los hloov AC lub zog rau hauv DC lub zog, yog li cov harmonics generated feem ntau yog thib tsib, xya, thiab kaum ib harmonics.Kev puas tsuaj ntawm kev sib haum xeeb hauv petrochemical system software tshwj xeeb yog tshwm sim hauv kev puas tsuaj rau hluav taws xob engineering thiab qhov ua yuam kev ntawm kev ntsuas raug.Cov kev tshawb fawb tau pom tias cov kev sib raug zoo tam sim no yuav ua rau poob ntxiv hauv lub transformer, uas yuav ua rau overheating, ua kom cov laus ntawm cov nruab nrab insulating, thiab ua rau cov rwb thaiv tsev puas.Lub hav zoov ntawm harmonics ua rau kom pom tseeb lub zog thiab muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm lub transformer.Tsis tas li ntawd, cov mem tes tam sim no muaj qhov cuam tshuam ncaj qha rau cov capacitors, disconnectors thiab cov khoom siv tiv thaiv relay hauv cov khoom siv hluav taws xob.Rau ntau cov cuab yeej ntsuas, lub hauv paus tiag tiag txhais tau tias square tus nqi ntsuas tsis tuaj yeem ntsuas, tab sis qhov nruab nrab tus nqi ntsuas tau, thiab tom qab ntawd qhov kev xav waveform yog sib npaug los ntawm qhov ntsuas qhov zoo kom tau txais tus nqi nyeem ntawv.Thaum cov kev sib haum xeeb loj heev, cov kev nyeem ntawv no yuav muaj qhov sib txawv loj, ua rau kev ntsuas qhov sib txawv.

Tej zaum koj yuav ntsib teeb meem?
1. Pib teeb meem ntawm ntau yam aviation cranes thiab twj tso kua mis
2. Lub zaus converter tsim muaj ntau yam kev sib haum xeeb, uas cuam tshuam rau kev nyab xeeb ntawm cov khoom siv hluav taws xob ntawm qhov system.
3. Reactive fais fab raug nplua los ntawm kev siv hluav taws xob tsawg (raws li lub zog hluav taws xob cov dej thiab hluav taws xob hloov kho txoj kev tsim los ntawm Ministry of Water Resources thiab Hluav Taws Xob ntawm peb lub tuam txhab thiab Lub Tuam Txhab Nqe ntawm peb lub tuam txhab);

Peb qhov kev daws teeb meem:
1. Txhim kho HD high-voltage reactive fais fab tsis siv neeg them nyiaj rau ntawm 6kV, 10kV lossis 35kV sab ntawm lub kaw lus kom them rov qab lub zog ntawm lub cev, txhim kho lub zog, tsim kom muaj txiaj ntsig zoo, thiab ib nrab tswj cov mem tes tam sim no. ntawm qhov system;
2. Lub siab-voltage sab ntawm lub kaw lus siv lub zog zoo dynamic rov qab system kom dynamically compensate reactive loads nyob rau hauv lub sij hawm thiab tswj kev ntseeg tau ntawm lub hwj chim zoo ntawm lub system;
3. Lub tshuab lim dej Hongyan APF tsis siv neeg tswj qhov ntsuas pulse tam sim no tau teeb tsa rau hauv qab voltage 0.4kV sab, thiab cov ntaub ntawv zoo li qub kev ruaj ntseg them nyiaj cov cuab yeej Hongyan TSF them nyiaj system software reactive load raug xaiv los txhim kho lub zog zoo.
