Isihlungi esisebenzayo sochungechunge lwe-HYAPF

imodeli yomkhiqizo

isicelo esijwayelekile
Njengamanje, imikhiqizo eyinhloko ihlukaniswe yaba izigaba ezimbili: imikhiqizo yokulawula i-harmonic kanye nemikhiqizo yesinxephezelo samandla asebenzayo.Izimboni ezihilelekile: ugwayi, uphethiloli, amandla kagesi, izindwangu, insimbi, insimbi, ezokuthutha ngojantshi, imboni yamakhemikhali epulasitiki, imithi, ukuxhumana, isiteshi sokushaja, imboni ye-photovoltaic, uMasipala, izakhiwo nezinye izimboni, okulandelayo yizimo eziningana ezijwayelekile.
1. Imboni yendwangu: Imithwalo eyinhloko i-UPS yomthamo omkhulu kanye nezinsimbi zekhompyutha.I-UPS ihlinzeka ngomthwalo ngamandla kagesi ekhwalithi ephezulu ngokunemba kokuqina kwamandla kagesi aphezulu kanye nokuhlanekezelwa kwe-waveform ephansi.Kodwa-ke, njengoba i-UPS ingumthwalo ongekho emthethweni, i-rectifier ku-UPS ikhiqiza inani elikhulu lamanje le-harmonic , ukuze izinga lamanje lokuhlanekezela ohlangothini lwegridi liphezulu kakhulu, okungabangeli nje ukungcoliswa kwe-harmonic kugridi, kodwa futhi kuthinte. okokufaka okujwayelekile kwekhabhinethi yamandla asebenzayo, nokulawulwa kwe-harmonic kufanele kwenziwe
2. Embonini yokuhlanza amanzi, injini yepompo yokungena kwamanzi iqhutshwa isiguquli sefrikhwensi yamandla aphezulu.Njengoba isiguquli se-frequency sidinga ukwenza ukulungiswa kwe-diode yamandla aphezulu kanye ne-high-power thyristor inverter, ngenxa yalokho, ama-harmonics amanje aphezulu akhiqizwa kumasekethe okokufaka nokukhiphayo, aphazamisa uhlelo lokunikezwa kwamandla.Umthwalo nezinye izinto zikagesi eziseduze zithinta ukusebenza okungavamile kwethuluzi le-metering, futhi ukulawulwa kwe-harmonic kufanele kwenziwe.
3. Imboni kagwayi: Umthwalo “yintambo yokubhula”.“Isibhulo” siwukuhluza ukungcola emaqabungeni kagwayi ukuze kutholakale amahlamvu kagwayi angenawo ukungcola.Le nqubo yenziwa ngokusebenzisa iziguquli zemvamisa namamotho.Isiguquli semvamisa singumthombo omkhulu kakhulu we-harmonic, ngakho-ke kuletha ukungcola okukhulu kwe-harmonic kanye nokuphazamiseka kwe-harmonic ohlelweni, futhi ukulawulwa kwe-harmonic kufanele kwenziwe.
4. Imboni yomshini wokuxhumana: I-UPS isiphenduke into esetshenziswayo egumbini lekhompyutha, i-UPS ingahlinzeka ngomthwalo
Amandla kagesi ekhwalithi ephezulu nokunemba kokuqina kwamandla kagesi aphezulu, imvamisa ezinzile, nokuhlanekezelwa kwe-waveform ephansi, futhi angafinyelela ukunikezwa kwamandla okungaphazanyiswa lapho ushintsha nge-bypass emile.Kodwa-ke, njengoba i-UPS ingumthwalo ongaqondile, izokhiqiza inani elikhulu lama-harmonics amanje.Nakuba igridi yamandla ibangela ukungcoliswa kwe-harmonic, iphinde ithinte nezinye izinto ezibucayi ekamelweni lekhompyutha, okubangela ukuphazamiseka okukhulu noma ngisho nokulimaza uhlelo lokuxhumana.Ngakho-ke, wonke amakamelo ekhompiyutha okuxhumana kufanele abhekane nenkinga yokulawula i-harmonic.
5. Ukuthutha ngololiwe: Ukuze kusabele obizweni lukazwelonke lokonga amandla kanye nokunciphisa ukusetshenziswa, inkampani yeqembu lesitimela esihamba ngaphansi komhlaba yanquma ukusebenzisa ama-inverters kumzila wesitimela ukuze kuguqulwe ugesi, futhi ngesikhathi esifanayo ilawule i-harmonic kuma-inverter.Ngemva kwesikhathi socwaningo, ukuze kwenziwe kangcono iphrojekthi yokuvuselela ukonga amandla, leli qembu lanquma ukwenza iphrojekthi yokuhlola ku-Rail Transit Line 4. Phakathi kwabo, i-converter ye-frequency ikhethwa emikhiqizweni ye-Schneider Co., Ltd. ., futhi isihlungi samandla esisebenzayo sikhethwa emikhiqizweni ye-Xi'an Xichi Power Technology Co., Ltd.
6. Insimbi ye-Metallurgical: Ngenxa yezidingo zokukhiqiza, okokusebenza okusohlangothini lwesibili lwe-transformer ohlelweni lokusatshalaliswa kwamandla aphansi-voltage ngokuyinhloko kuyinjini, futhi isiguquli semvamisa sishayela injini ukuthi isebenze.Njengoba isakhiwo sangaphakathi sokuguqula imvamisa sisebenzisa inani elikhulu lezingxenye ezingezona eziqondile, inani elikhulu lama-harmonics likhiqizwa ngesikhathi senqubo yokusebenza.Kunomthwalo othile womthelela phakathi nenqubo yokugingqika kwepuleti, futhi inqubo yokukhiqiza ayiqhubeki, okubangela ukuguquguquka nokungaqhubeki ku-voltage/okwamanje, futhi izinguquko kumanje osebenzayo nazo zibangela ukushintshashintsha kwamanje kwe-harmonic.
