Active power filter apf imhando nyowani yemagetsi mudziyo wekusefa zvine simba kweharmonic wave uye reactive simba muripo.Inogona kuitisa chaiyo-nguva kusefa uye muripo kune harmonic wave (ese saizi uye frequency inoshandurwa) uye ine simba reactive simba, uye inoshandiswa kukurira zvipingamupinyi zvechinyakare harmonic kudzvinyirirwa uye reactive muripo nzira dzechinyakare mafirita, nokudaro kuona yakarongeka harmonic kusefa basa uye reactive simba muripo webasa.Mukuwedzera, inoshandiswa zvakanyanya musimba, metallurgy.petroleum, port, makemikari uye maindasitiri uye mabhizinesi emigodhi.
Active harmonic sefa inotora yepamusoro modular dhizaini.Iyo inoshanda sefa system ine imwe kana akati wandei AHF module uye sarudzo yekubata screen HMI.Imwe neimwe AHF module ndeye yakazvimirira harmonic kusefa system, uye vashandisi vanogona kushandura kumisikidzwa kweiyo harmonic kusefa system nekuwedzera kana kubvisa AHF module.
Iyo AHF inowanikwa mumatatu ekumisikidza modes: rack yakaiswa, madziro akaiswa, kabati akaiswa.
1. Modular dhizaini, chero kutadza kwemodule hakuzokanganisa kushanda kwakajairika kwemamwe ma module, zvakanyanya kuvandudza kuvimbika kwemidziyo yese;inogona kuzadzisa kuwedzera kwakatsetseka kweakawanda akananga parallel operation.The master-slave control mode inoshandiswa kana zvikwata zvakawanda zvichiwedzerwa;apo akawanda mamodule akabatanidzwa mukufanana, ese mamodule anogona kugovera seti yezvino shanduri.
2. Izvo zvisinganzwisisike-zvakarongeka harmonic currents ye2 kusvika ku50 nguva kana zvishoma zvinogona kusefa panguva imwe chete, uye harmonics yemhando gumi nenhatu yekusefa inogona kuiswa sezvinodiwa.Kana mutoro wezvino kukanganisa kukanganisa> 20%, kwete pasi pe85%;apo mutoro wezvino kukanganisa chiyero chiri <20%, kwete pasi pe75%;reactive simba muripo anogona kuita kuti simba factor isvike 1;iyo mitatu-chikamu ikozvino kusaenzana kunogona kugadziriswa kuti ipedze kuenzanisa;
3. Shandisa chizvarwa chechishanu IGBT yemhando yepasi rose inozivikanwa, inogona kugadzirisa otomatiki kuburitsa zvinoenderana neharmonic ikozvino yemutoro, uye dynamically sefa;
4. Shandisa American Xilinx mauto-giredhi FPGA control chip, ine kukurumidza kumhanya kumhanya uye yakakwirira kuvimbika;
5. Nekugadzirwa kwemavara, guruva nemvura hazvizonamatira kubhodhi redunhu, kugadzirisa kushandiswa pasi pemamiriro ezvinhu akaoma;
6. Kusefa, kubhadhara simba rinoshanda, kubhadhara kune-nhatu-phase unbalance inogona kuva imwe-yakasarudzwa kana yakawanda-yakasarudzwa, uye inogona kuisa kukosha kwemabasa;
7. Shandisa iyo iterative DFT yekuona algorithm yewindo rinotsvedza, kukurumidza kuverenga kunokurumidza, nguva yekupindura kwenguva pfupi iri pasi pe 0.1ms, uye nguva yakazara yekupindura kwechigadzirwa chekugadzirisa iri pasi pe20ms;
8. Kubuda kwesefa kunoshandisa LCL chimiro chekubatanidza kune gridhi, uye iyo yega-yepamusoro-frequency carrier haidyi shure kune gridhi, uye hapana kupindira kune mamwe maturusi mumagetsi ekugovera simba;
9. Kuzadza mabasa ekudzivirira, kusanganisira over-voltage, over-current, over-heat, short-circuit uye mamwe mabasa ekudzivirira akazara, pamwe chete nehurongwa hwekuzviongorora basa;
10. Iine yakapfava yekutanga yekudzora loop kudzivirira yakawandisa inrush ikozvino panguva yekutanga, uye inoganhura ikozvino pakati peyakayerwa mitsara;
11. Shandisa yakavimbika yazvino yekumisikidza control link.Kana iyo yazvino yekubhadharwa muhurongwa yakakura kupfuura yakayerwa kugona kwechishandiso, mudziyo unogona kudzikamisa kuburitsa kusvika ku100% huwandu, chengetedza kushanda kwakajairika, uye pasina zvikanganiso sekupisa zvakanyanya;
12. Dunhu guru rinoshandisa matatu-level topology, uye yakabuda waveform ine yemhando yepamusoro uye yakaderera switching kurasikirwa;
13. The wall mounted module inouya ne 4.3 touch screen for parameter setting, parameter viewing, status viewing, chiitiko chekuona uye nezvimwe.Inogonawo kutariswa nechepakati nepamusoro-definition 7-inch touch screen, iyo iri nyore kushanda.Iyo skrini inoratidza sisitimu uye mudziyo unoshanda paramita munguva chaiyo, uye ine kukanganisa alarm basa.
14. Chengetedza nzvimbo yevashandisi, simba guru re 600mm yakafara kabati ndeye 300A/200kvar, uye simba re 800mm yakafara cabinet inogona kusvika 750A/500kvar.
Mushure mekuvhara kwedunhu kuvharwa, kuitira kudzivirira iko pakarepo kukanganiswa kwegidhi paDC bhazi capacitors panguva yemagetsi-on, iyo APF/SVG yekutanga.lyinochaja iyo DC bhazi capacitor kuburikidza neyakapfava-kutanga resistor.Kana bhazi voltage Udc inosvika kukosha kwakafanotemerwa, iyo huru contactor yakavharwa.Sesimba rekuchengetedza simba, iyo DC capacitor inopa simba kune yekunze kubuda kweiyo muripo wezvino kuburikidza neIGBT. inverter uye yemukati reactor.Iyo APF / SVG inotumira chiratidzo chemazuva ano kuburikidza nekunze CT kune chiratidzo chekugadzirisa dunhu uye ipapo kune mutongi.Mutongi anoparadza sampling ikozvino, anobvisa imwe neimwe harmonic ikozvino, reactive current, uye matatu-phase unbalanced current. , uye inoenzanisa chikamu chezvino chakaunganidzwa kuti chibhadharwe pamwe nemuripo wezvino waitwasentneAPF/SVG kuti uwane mutsauko.Iyo chaiyo-nguva yekubhadhara chiratidzo inobuda kune yekutyaira dunhu, uye iyo IGBT inoshandura inokonzereswa kupinza muripo wezvino mugedhi remagetsi kuti uone yakavharwa-loop control uye kupedzisa basa remuripo.
Iyo inoshanda harmonic sefa inoshanda pane 3-level isina kwayakarerekera point yakasungirirwa(NPC) topology.Sezvinoratidzwa pamusoro, iyo yechinyakare 2-level topology yedunhu dhizaini ine 6 IGBTs ( 2 IGBT magetsi emagetsi papini yega yega yepini uye yazvino nzira ), uye mune 3-level topology, kune gumi nemaviri IGBTs ( muchikamu chimwe nechimwe 4 IGBT. zvishandiso zvemagetsi pamapini uye nzira dzazvino ).
Iyo 3-level topology wedunhu inogona kuburitsa matatu voltage mazinga pane inobuda, kusanganisira DC bhazi positive voltage, zero voltage uye DC bhazi negative voltage.Maviri-level topology wedunhu anogona chete kuburitsa zvakanaka uye zvisina kunaka voltages.Panguva imwecheteyo, iyo matatu-level topology wedunhu zvakare inova nechokwadi chemhando yepamusoro uye zvirinani harmonic inobuda magetsi, nekudaro ichidzikisa inobuda mafirita zvinodiwa uye mari yakabatana.
