Isihlungi samandla asebenzayo siwuhlobo olusha lwedivayisi ye-elekthronikhi yokuhlunga okuguquguqukayo kwegagasi elivumelanayo kanye nesinxephezelo samandla asebenzayo.Ingakwazi ukwenza ukuhlunga kwesikhathi sangempela kanye nesinxephezelo kumagagasi e-harmonic (kokubili usayizi kanye nemvamisa kuyashintshwa) kanye namandla ashukumisayo asebenzayo, futhi isetshenziselwa ukunqoba ukungalungi kokucindezelwa kwe-harmonic yendabuko kanye nezindlela zesinxephezelo esisebenzayo sezihlungi zendabuko, ngaleyo ndlela ibone umsebenzi wokuhlunga we-harmonic ohlelekile futhi umsebenzi wesinxephezelo samandla asebenzayo.Ngaphezu kwalokho, isetshenziswa kabanzi amandla, metallurgy.amabhizinisi e-petroleum, amachweba, amakhemikhali nezimboni kanye nezimayini.

Ikhabhinethi yesihlungi samandla esebenzayo iqukethe imojuli ye-AHF eyodwa noma amaningana kanye ne-HMI yesikrini esithintwayo ozikhethela sona.Imojula ngayinye ye-AHF iwuhlelo oluzimele lokuhlunga lwe-harmonic, futhi abasebenzisi bangashintsha ukucushwa kwesistimu yokuhlunga ye-harmonic ngokungeza noma ngokukhipha amamojula we-AHF.

1. Idizayini ye-Modular, noma yikuphi ukwehluleka kwemojula ngeke kuthinte ukusebenza okuvamile kwamanye amamojula, kuthuthukisa kakhulu ukuthembeka kwayo yonke imishini;ingafinyelela ukwandiswa okushelelayo kokusebenza okuningi okuhambisanayo okuqondile.Imodi yokulawula isigqila isetshenziswa lapho amayunithi amaningi enwetshwa;lapho amamojula amaningi exhunywe ngokufana, wonke amamojula angabelana ngesethi yama-transformer amanje.
2. Imisinga ye-harmonic ye-oda eliyinqaba yezikhathi ezi-2 kuya kwezingu-50 noma ngaphansi ingahlungwa ngesikhathi esifanayo, futhi ukuvumelana kwezinhlobo ezingu-13 zokuhlunga kungasethwa njengoba kudingekile.Lapho izinga lokulayisha lamanje lokuhlanekezela li>20%, hhayi ngaphansi kwama-85%;lapho izinga lokuhlanekezela lamanje lomthwalo lingu-<20%, hhayi ngaphansi kuka-75%;isinxephezelo samandla asebenzayo singenza isici samandla sifinyelele ku-1;ukungalingani kwamanje kwezigaba ezintathu kungalungiswa ukuze kugcwalise ibhalansi;
3. Sebenzisa i-IGBT yesizukulwane sesihlanu yomkhiqizo owaziwayo wamazwe ngamazwe ongenisiwe, ingakwazi ukulungisa ngokuzenzakalelayo okukhiphayo ngokuya nge-harmonic yamanje yomthwalo, futhi isihlungi ngokuguqukayo;
4. Sebenzisa i-chip yokulawula ye-FPGA ye-American Xilinx yezinga lezempi, enejubane elisheshayo nokuthembeka okuphezulu;
5. Ngomklamo owenziwe ngezingqimba, uthuli nemvula ngeke kuhambisane nebhodi lesifunda, livumelane nokusetshenziswa ngaphansi kwezimo ezinzima;
6. Ukuhlunga, ukunxephezela amandla asebenzayo, ukunxephezela ukungalingani kwezigaba ezintathu kungakhethwa kanye noma kukhethwe kaningi, futhi kungasetha ukubaluleka kwemisebenzi;
7. Sebenzisa i-algorithm yokuthola i-DFT ephindaphindwayo yewindi elislayidayo, isivinini sokubala siyashesha, isikhathi sokuphendula esidlulayo singaphansi kuka-0.1ms, futhi isikhathi sokuphendula esigcwele sesinxephezelo sedivayisi singaphansi kuka-20ms;

8. Ukuhlunga okukhiphayo kusebenzisa ukwakheka kwe-LCL ukuze kuxhumeke kugridi, futhi inkampani yayo yenethiwekhi enemvamisa ephezulu ayiphakeli emuva kugridi, futhi akukho ukuphazamiseka kwamanye amadivayisi ohlelweni lokusabalalisa amandla;
9. Qedela imisebenzi yokuvikela, ehlanganisa amandla kagesi angaphezulu, ukwanda kwamanje, ukushisa ngokweqile, i-short-circuit kanye neminye imisebenzi yokuvikela ephelele, kanye nomsebenzi wokuzihlolela isistimu;
10. Ine-loop yokulawula isiqalo esithambile ukuze ugweme ukungena ngokweqile ngesikhathi iqala, futhi ikhawulela igagasi phakathi kobubanzi obulinganiselwe;
11. Sebenzisa isixhumanisi esinokwethenjelwa sokulawula ukukhawula samanje.Uma okwamanje okuzonxeshezelwa ohlelweni kungaphezu komthamo olinganiselwe wedivayisi, idivayisi ingakhawulela ngokuzenzakalela okukhiphayo kumthamo ongu-100%, igcine ukusebenza okuvamile, futhi awekho amaphutha njengokushiswa kokulayishwa ngokweqile;
12. Isifunda esiyinhloko sisebenzisa i-topology yamazinga amathathu, futhi i-waveform ephumayo inekhwalithi ephezulu nokulahlekelwa kokushintsha okuphansi;
13. I-module efakwe odongeni ifika nesikrini sokuthinta esingu-4.3 sokusetha ipharamitha, ukubuka ipharamitha, ukubuka isimo, ukubukwa kwemicimbi nokunye.Ingabuye igadwe maphakathi ne-high-definition 7-inch touch screen, okulula ukuyisebenzisa.Isikrini sibonisa isistimu nemingcele yokusebenza kwedivayisi ngesikhathi sangempela, futhi sinomsebenzi we-alamu onephutha.
14. Yonga isikhala kubasebenzisi, amandla amakhulu ekhabhinethi engu-600mm ububanzi ngu-300A/200kvar, futhi amandla ekhabhinethi engu-800mm ububanzi angafinyelela ku-750A/500kvar.

Ngemuva kokuthi i-breaker yesifunda ivaliwe, ukuze kuvinjelwe umthelela osheshayo wegridi kuma-capacitor webhasi le-DC ngesikhathi sokukhanyisa, i-APF/SVG kuqalalyishaja i-DC bus capacitor nge-soft-start resistor.Lapho i-voltage yebhasi i-Udc ifinyelela inani elinqunywe kusengaphambili, i-contactor eyinhloko ivaliwe.Njengedivayisi yokugcina amandla, i-DC capacitor inikeza amandla ekuphumeni kwangaphandle kwesinxephezelo samanje nge-IGBT. i-inverter kanye ne-reactor yangaphakathi.I-APF/SVG ithumela isignali yamanje nge-CT yangaphandle kwisekethe yesimo sesignali bese isiya kusilawuli.Isilawuli sichitha isampula yamanje, sikhipha i-harmonic current, i-reactive current, kanye nesigaba sesithathu esingalingani. , futhi iqhathanise ingxenye yamanje eqoqiwe ukuze inxeshezelwe nesikhathi sesinxephezelo esikhonaithunyelwenge-APF/SVG ukuze uthole umehluko.Isignali yesinxephezelo sesikhathi sangempela iphuma kumjikelezo wokushayela, futhi isiguquli se-IGBT siqaliswa ukujova isinxephezelo samanje kugridi yamandla ukuze kutholakale ukulawula kweluphu evaliwe futhi kuqedelwe umsebenzi wesinxephezelo.

Isihlungi se-harmonic esisebenzayo sisebenza ku-topology yezinga eli-3 elingathathi hlangothi elicishiwe(NPC).Njengoba kukhonjisiwe kulokhu okungenhla, ukwakheka kwesekethe yezinga eliphezulu ye-topology engokwesiko iqukethe ama-IGBT ayi-6 (imishini engu-2 IGBT yamandla kuphini ngalinye lesigaba nendlela yamanje), futhi ku-topology yamazinga angu-3, kukhona ama-IGBT angu-12( esigabeni ngasinye 4 IGBT. amadivayisi amandla kumaphini nasezindleleni zamanje ).

Isekhethi ye-topology enamazinga ama-3 ingakhiqiza amazinga kagesi amathathu kokuphumayo, okuhlanganisa ivolthi yebhasi ye-DC eyakhayo, i-voltage enguziro kanye nevolthi ye-DC yebhasi ye-DC.Isekhethi ye-topology enamazinga amabili ingakhipha kuphela ama-voltages avumayo noma angalungile.Ngasikhathi sinye, isekethe ye-topology enamazinga amathathu iphinde iqinisekise ikhwalithi ephezulu kanye ne-harmonic ephumayo kagesi engcono, ngaleyo ndlela yehlise izidingo zokuhlunga okukhiphayo nezindleko ezihambisanayo.
