I-Voltage Waveform Distortion of Power Generating Sets

I-waveform efanelekile ye-voltage ephumayo yesethi ye-generator kufanele ibe igagasi eline-sine, kodwa i-waveform yalo yangempela ayilona igagasi le-sine langempela.Ayiqukethe kuphela igagasi eliyisisekelo, kodwa futhi nama-harmonics amathathu noma ngaphezulu.I-generator isethi ejatshuliswe yi-harmonic yesithathu ibucayi kakhulu.Iphesenti levelu eyisikwele yempande ye-harmonic ngayinye eguqulelwe enanini elisebenzayo eliyisisekelo libizwa ngokuthi izinga lokuhlanekezelwa kwe-voltage waveform.Ngokuvamile, izinga lokuhlanekezelwa kwe-waveform ye-voltage engalinganiselwe yesethi ye-generator kufanele ibe ngaphansi kuka-10%.Uma izinga lokuhlanekezela le-voltage waveform likhulu kakhulu, i-generator izoshisa kakhulu, izinga lokushisa lizokhuphuka, futhi ukufakwa kwe-generator kuzolimala, kuthinte ukusebenza okuvamile kwesethi ye-generator.

Ukulungiswa kobubanzi be-voltage engalayishiwe ye amandla & amasethi okukhiqiza : lapho iyunithi isebenza ngokuzinzile, i-voltage yayo engalayishiwe izokwazi ukulungiswa phakathi kwebanga elithile, okubangelwa ukwehla okuthile kwe-voltage yekhebula phakathi kweyunithi nezinto zikagesi.Iyunithi izoqinisekisa ukuthi isiphetho sekhebuli ephumayo sisenayo i-voltage evamile yokusebenza ngaphansi komthwalo othile.Ngokuvamile, uhla lokulungisa i-voltage engekho umthwalo ungama-95% ~ 105% we-voltage elinganisiwe.Isibonelo, uma i-voltage elinganiselwe yeyunithi ingu-400V, ububanzi bokulungiswa kwe-voltage engekho umthwalo ngu-380 ~ 420v.

I-Voltage thermal offset: lapho izinga lokushisa le-ambient kanye nezinga lokushisa le-generator likhuphuka likhuphuka, ukufinyeleleka kwe-generator core kuncipha, ukumelana kwe-DC kokuma kokuphenduka kuyanda, kanye namapharamitha we-circuit element azoshintsha, okuholela ekushintsheni kwamandla kagesi okukhiphayo. isethi ye-generator.Lesi simo sibizwa ngokuthi i-voltage thermal offset.Ngokuvamile, i-voltage thermal offset yeyunithi ivezwa njengephesenti lokushintsha kwamandla kagesi weyunithi okubangelwa ukunyuka kwezinga lokushisa ku-voltage elinganiselwe, ngokuvamile engavunyelwe ukuba yeqe u-2%

Izinga lokuhlanekezela kwe-voltage waveform: I-waveform efanelekile ye-voltage ephumayo yesethi ye-generator kufanele ibe i-sine wave, kodwa i-waveform yayo yangempela ayilona igagasi le-sine langempela.Ayiqukethe kuphela igagasi eliyisisekelo, kodwa futhi i-harmonics yesithathu nangaphezulu, kanye nenjabulo yesithathu ye-harmonic Isethi ye-generator ibaluleke kakhulu.Amaphesenti omsuka wenani eliyisikwele yenani elisebenzayo le-harmonic ngayinye enanini elisebenzayo legagasi eliyisisekelo libizwa ngokuthi izinga lokuhlanekezela kwe-voltage waveform.Ngokuvamile, izinga lokuhlanekezela le-waveform ye-voltage engalinganiselwe yesethi ye-generator kufanele ibe ngaphansi kuka-10%.Uma izinga lokuhlanekezelwa kwe-voltage waveform likhulu kakhulu, ijeneretha izokhiqiza ukushisa okukhulu, futhi izinga lokushisa lizolimaza ukufakwa kwe-generator, okuzothinta ukusebenza okuvamile kwesethi ye-generator.

Izinga lokulawulwa kwamandla kagesi ezinzile: Izinga lokulawulwa kwamandla kagesi ezinzile lisho izinga lokuchezuka kukagesi ozinzile weyunithi ngemva kokushintshwa komthwalo osuka ku-voltage olinganiselwe weyunithi lapho ungalayishi, ovezwa ngamaphesenti.Okusho ukuthi, iphesenti lesilinganiso somehluko phakathi kwe-voltage ephumayo yeyunithi kanye ne-voltage elinganiselwe ku-voltage elinganiselwe.Isimo esizinzile ukulawulwa kwamandla kagesi isilinganiso siyinkomba ebalulekile yokukala ukuqina kwamandla kagesi wesethi yejeneretha.Uma izinga lokulawulwa kwamandla kagesi liba lincane, kuba mncane umthelela wokushintsha komthwalo ku-voltage yokugcina yeyunithi, futhi kuba phezulu ukuzinza kwe-terminal voltage yesethi yejeneretha.

Izinga lokulawulwa kwamandla kagesi elizinzile lihlukile ngaphansi kwemithwalo ehlukene.Ngaphansi komthwalo we-inductive, i-voltage ezinzile ngemva kokushintshwa komthwalo iphansi kune-voltage engalinganiselwe.Ngaphansi komthwalo we-capacitive, i-voltage ezinzile ngemva kokushintshwa komthwalo iphezulu kune-voltage engalinganiselwe.Ukuchezuka ku-voltage engalinganisiwe yomthwalo kuncike kumthamo wokulawula wesilawuli esivusa amadlingozi.Uma amandla okulawula aqina, inani lokuchezuka liba lincane, izinga lokulawulwa kwamandla kagesi liba lincane, futhi izinga lokushisa lomthamo weyunithi lizinzile.

I-Guangxi Dingbo Power Equipment Manufacturing Co., Ltd iyimboni yamajeneretha kagesi, okuhlanganisa ijeneretha yohlobo oluvulekile, ijeneretha ethule, i-canopy ggenerator, i-container generator kanye ne-trailer generator njll. Uma unohlelo lokuthenga muva nje, wamukelekile ukusithinta nge-imeyili dingbo@dieselgeneratortech .com, sizokuphendula noma kunini.
