Isihluzi samandla asebenzayo apf luhlobo olutsha lwesixhobo sombane sokuhluza okuguquguqukayo kwamaza eharmonic kunye nembuyekezo yamandla asebenzayo.Inokuqhuba ukuhluzwa kwexesha lokwenyani kunye nembuyekezo kumaza e-harmonic (zombini ubungakanani kunye nokuphindaphinda zitshintshiwe) kunye namandla aguqukayo asebenzayo, kwaye isetyenziselwa ukoyisa ukungalungi kokucinezelwa kwe-harmonic yemveli kunye neendlela zembuyekezo ezisebenzayo zezihluzo zemveli, ngaloo ndlela iqonda umsebenzi wokucoca we-harmonic ocwangcisiweyo kunye. umsebenzi wembuyekezo yamandla asebenzayo.Ukongeza, isetyenziswa ngokubanzi amandla, metallurgy.i-petroleum, izibuko, iikhemikhali kunye nezoshishino kunye namashishini emigodi.
Isihluzi esisebenzayo se-harmonic samkela uyilo oluphambili lweemodyuli.Inkqubo yokucoca esebenzayo inemodyuli enye okanye ezininzi ze-AHF kunye ne-HMI ekhethiweyo yesikrini.Imodyuli nganye ye-AHF yinkqubo yokucoca i-harmonic ezimeleyo, kwaye abasebenzisi banokutshintsha ukucwangciswa kwenkqubo yokucoca i-harmonic ngokongeza okanye ukususa iimodyuli ze-AHF.
I-AHF ifumaneka kwiindlela ezintathu zokunyuka: i-rack ifakwe, ifakwe eludongeni, ifakwe kwikhabhinethi.
1. Uyilo lwemodyuli, nayiphi na imodyuli engaphumeleli ayiyi kuchaphazela ukusebenza okuqhelekileyo kwezinye iimodyuli, ukuphucula kakhulu ukuthembeka kwezixhobo zonke;inokufezekisa ukwandiswa okugudileyo kokusebenza ngokuhambelana ngokuthe ngqo.Imowudi yolawulo lwekhoboka isetyenziswa xa iiyunithi ezininzi zandiswa;xa iimodyuli ezininzi zixhunyiwe ngokufanayo, zonke iimodyuli zingabelana ngesethi yabaguquli bangoku.
2. Iindlela ezingaqhelekanga ze-harmonic currents ze-2 ukuya ku-50 amaxesha okanye ngaphantsi ziyakwazi ukuhluzwa ngexesha elifanayo, kwaye i-harmonics yeentlobo ze-13 zokucoca zingasetwa njengoko kufuneka. hayi ngaphantsi kwama-85%;xa izinga lokuphazamiseka kwangoku lomthwalo <20%, lingekho ngaphantsi kwe-75%;imbuyekezo yamandla asebenzayo inokwenza into yamandla ifikelele kwi-1;ukungalingani kwangoku kwesigaba sesithathu kunokulungiswa ukugqiba ibhalansi;
3. Sebenzisa i-IGBT yesizukulwana sesihlanu se-brand eyaziwayo kumazwe ngamazwe, inokulungelelanisa ngokuzenzekelayo imveliso ngokwe-harmonic current yomthwalo, kunye ne-dynamically filter;
4. Sebenzisa i-American Xilinx yomkhosi we-FPGA yolawulo lwe-chip, enesantya esihamba ngokukhawuleza kunye nokuthembeka okuphezulu;
5. Ngoyilo olucwangcisiweyo, uthuli kunye nemvula aziyi kubambelela kwibhodi yesiphaluka, ukulungelelanisa ukusetyenziswa phantsi kweemeko ezinzima;
6. Ukucoca, ukuhlawulela amandla asebenzayo, ukuhlawulela ukungalingani kwesigaba esithathu kunokukhethwa-nye okanye kukhethwe ngeendlela ezininzi, kwaye kunokubeka phambili imisebenzi ephambili;
7. Sebenzisa i-algorithm yokufumanisa i-DFT ephindaphindiweyo yefestile ye-sliding, isantya sokubala ngokukhawuleza, ixesha lokuphendula elidlulayo lingaphantsi kwe-0.1ms, kwaye ixesha elipheleleyo lokuphendula lembuyekezo yesixhobo lingaphantsi kwe-20ms;
8. Ukucoca okuphumayo kusebenzisa isakhiwo se-LCL ukudibanisa kwigridi, kwaye i-carrier yayo ye-high-frequency carrier ayifuni ukubuyela kwigridi, kwaye akukho ukuphazamiseka kwezinye izixhobo kwinkqubo yokusabalalisa amandla;
9. Gqibezela imisebenzi yokukhusela, kubandakanywa i-over-voltage, over-current, over-heat, short-circuit kunye neminye imisebenzi yokukhusela epheleleyo, kunye nomsebenzi wokuzixilonga;
10. Inesiqalo esithambileyo sokulawula i-loop ukuphepha ukugqithisa ngokugqithisileyo okwangoku ngexesha lokuqalisa, kunye nokunciphisa okwangoku phakathi koluhlu olulinganisiweyo;
11. Sebenzisa ikhonkco elithembekileyo lokulawula umda.Xa umbane oza kuhlawulwa kwisistim umkhulu kunomthamo olinganisiweyo wesixhobo, isixhobo sinokukhawulela ngokuzenzekelayo imveliso ukuya kwi-100% umthamo, ugcine ukusebenza okuqhelekileyo, kwaye akukho ziphoso ezifana nokutshisa okugqithisileyo;
12. Isekethe ephambili isebenzisa i-topology yamanqanaba amathathu, kunye ne-output waveform inomgangatho ophezulu kunye nelahleko ephantsi yokutshintsha;
13. Imodyuli efakwe eludongeni ifika kunye ne-4.3 yesikrini sokuthintela i-parameter setting, ukujonga ipharamitha, ukujonga isimo, ukubonwa kwesiganeko kunye nokunye.Inokuthi iphinde ibekwe esweni kwi-high-definition ye-7-inch touch screen, ekulula ukuyisebenzisa.Isikrini sibonisa inkqubo kunye neeparamitha zokusebenza kwesixhobo ngexesha langempela, kwaye inomsebenzi we-alarm onephutha.
14. Gcina indawo yabasebenzisi, amandla aphezulu e-600mm ebanzi yekhabhinethi yi-300A / 200kvar, kwaye amandla e-800mm ebanzi yekhabhinethi anokufikelela kwi-750A / 500kvar.
Emva kokuba i-breaker circuit ivaliwe, ukwenzela ukukhusela impembelelo esheshayo yegridi kwi-DC capacitors yebhasi ngexesha lombane, i-APF / SVG kuqalalyihlawulisa i-DC bus capacitor ngokusebenzisa i-soft-start resistor.Xa i-voltage yebhasi i-Udc ifikelela kwixabiso elimiselweyo, i-contactor engundoqo ivaliwe. Njengesixhobo sokugcina amandla, i-DC capacitor inika amandla kwimveliso yangaphandle yembuyekezo yangoku nge-IGBT. i-inverter kunye ne-reactor yangaphakathi.I-APF / SVG ithumela isignali yangoku nge-CT yangaphandle kwisekethe yokulungelelanisa umqondiso kwaye emva koko kumlawuli.Umlawuli uchitha isampuli yangoku, ukhupha i-harmonic current, i-reactive current, kunye nesigaba sesithathu esingalinganiyo okwangoku. , kwaye uthelekise icandelo langoku eliqokelelweyo ukuze lihlawulwe kunye nembuyekezo yangoku esele yenziweithunyelwenge-APF/SVG ukufumana umahluko.Isignali yembuyekezo yexesha langempela iphuma kwisiphaluka sokuqhuba, kwaye i-IGBT converter ishukunyiswa ukuba ifake imbuyekezo yangoku kwigridi yamandla ukuze iqonde ulawulo oluvaliweyo kunye nokugqiba umsebenzi wembuyekezo.
Isihluzo esisebenzayo se-harmonic sisebenza kwinqanaba le-3 lendawo engathathi hlangothi ebambelweyo (NPC) topology.Njengoko kubonisiwe apha ngasentla, isakhiwo sesekethe ye-2-level topology circuit iqulethe i-6 IGBTs (izixhobo ze-2 IGBT zamandla kwi-pin yesigaba ngasinye kunye nendlela yangoku), kunye ne-topology yezinga le-3, kukho i-12 IGBTs (kwisigaba ngasinye 4 IGBT izixhobo zamandla kwizikhonkwane kunye neendlela zangoku ).
Isekethe ye-topology enemigangatho emi-3 inokuvelisa amanqanaba ombane amathathu kwimveliso, kubandakanywa amandla ombane we-DC bus positive, i-0 volt kunye ne-DC ye-negative voltage yebhasi.Isekethe ye-topology enamanqanaba amabini inokukhupha kuphela iivoltages ezilungileyo nezingalunganga.Kwangelo xesha, isekethe ye-topology enamanqanaba amathathu ikwaqinisekisa umgangatho ophezulu kunye nomthamo ongcono we-harmonic wokuphuma, ngaloo ndlela kuncitshiswa iimfuno zokucoca imveliso kunye neendleko ezinxulumene noko.
