mankhwala chitsanzo

ntchito yeniyeni
Pakadali pano, zinthu zazikuluzikulu zimagawidwa m'magulu awiri: zinthu zowongolera za harmonic ndi zowongolera zamagetsi.Mafakitale omwe amakhudzidwa: fodya, mafuta, magetsi, nsalu, zitsulo, zitsulo, zoyendera njanji, mafakitale apulasitiki, mankhwala, kulumikizana, malo opangira ma photovoltaic, Municipal, nyumba ndi mafakitale ena, zotsatirazi ndizochitika zingapo.
1. Makampani opanga nsalu: Zinthu zazikuluzikulu ndi UPS zazikulu komanso zida zamakompyuta.UPS imapereka katunduyo ndi mphamvu yamagetsi yapamwamba kwambiri yokhala ndi kukhazikika kwamphamvu kwamagetsi komanso kupotoza kwa mawonekedwe otsika.Komabe, popeza UPS ndi katundu wosagwirizana, wokonzanso mu UPS amapanga kuchuluka kwa ma harmonic current , kotero kuti kusokonezeka kwaposachedwa pamagulu a gululi ndipamwamba kwambiri, zomwe sizimangoyambitsa kuwonongeka kwa gridi, komanso kumakhudza kwambiri. kulowetsedwa kwabwino kwa kabati yogwira ntchito, ndikuwongolera kwa harmonic kuyenera kuchitika
2. M'makampani opangira madzi, injini ya mpope yolowera madzi imayendetsedwa ndi otembenuza ma frequency amphamvu kwambiri.Popeza osinthira pafupipafupi amafunikira kukonzanso ma diode amphamvu kwambiri komanso inverter yamphamvu kwambiri ya thyristor, chifukwa chake, ma harmonics amakono amapangidwa m'magawo olowera ndi otulutsa, omwe amasokoneza dongosolo lamagetsi.Katundu ndi zida zina zamagetsi zoyandikana nazo zimakhudza magwiridwe antchito amtundu wa metering, ndipo kuwongolera kwa harmonic kuyenera kuchitika.
3. Makampani a fodya: Katundu wake ndi “chingwe chopunthira”.“Chingwe chopunthira” ndiko kusefa zonyansa za masamba a fodya kuti tipeze masamba a fodya opanda zodetsa.Izi zimachitika kudzera mu converter pafupipafupi ndi ma motors.The frequency converter ndi gwero lalikulu kwambiri la harmonic, chifukwa chake limabweretsa kuyipitsa kwakukulu komanso kusokoneza kwa ma harmonic ku dongosolo, ndipo kuwongolera kwa harmonic kuyenera kuchitika.
4. Makampani opanga makina olankhulana: UPS yakhala chida chofunikira kwambiri m'chipinda cha makompyuta, UPS imatha kupereka katundu
Mphamvu yamagetsi yapamwamba kwambiri yokhazikika yokhazikika, ma frequency okhazikika, ndi kupotoza kwa mawonekedwe otsika, ndipo imatha kupeza mphamvu yosasokoneza mukasintha ndi static bypass.Komabe, popeza UPS ndi katundu wopanda mzere, ipanga kuchuluka kwa ma harmonics apano.Ngakhale gridi yamagetsi imayambitsa kuipitsa kwa harmonic, imakhudzanso zida zina zapakompyuta, zomwe zimapangitsa kusokoneza kwakukulu kapena kuvulaza njira yolumikizirana.Chifukwa chake, zipinda zonse zamakompyuta zolumikizirana ziyenera kukumana ndi vuto la kuwongolera kwa ma harmonic.
5. Sitima yapamtunda: Pofuna kuyankha kuyitanidwa kwa dziko kuti apulumutse mphamvu ndi kuchepetsa kugwiritsira ntchito mphamvu, kampani yapansi panthaka inaganiza zogwiritsa ntchito ma inverters mumayendedwe a njanji kuti asinthe mphamvu zopulumutsa mphamvu, ndipo panthawi imodzimodziyo azichita ulamuliro wa harmonic pa ma inverters.Pambuyo pa nthawi ya kafukufuku, kuti akwaniritse bwino ntchito yokonzanso mphamvu yopulumutsa mphamvu, gululo linaganiza zoyendetsa polojekiti ya Rail Transit Line 4. Pakati pawo, wosinthira pafupipafupi amasankhidwa kuchokera kuzinthu za Schneider Co., Ltd. ., ndipo fyuluta yamagetsi yogwira ntchito imasankhidwa kuchokera ku Xi'an Xichi Power Technology Co., Ltd.
6. Chitsulo chachitsulo: Chifukwa cha zofunikira zopanga, zida zomwe zili kumbali yachiwiri ya thiransifoma mu njira yogawa mphamvu yamagetsi otsika kwambiri ndi injini, ndipo makina osinthira pafupipafupi amayendetsa galimoto kuti agwire ntchito.Popeza mawonekedwe amkati a otembenuza pafupipafupi amagwiritsa ntchito zigawo zambiri zopanda malire, ma harmonics ambiri amapangidwa panthawi yogwira ntchito.Pali zina zimakhudza katundu pa akugubuduza ndondomeko mbale, ndi kupanga ndondomeko si mosalekeza, zomwe zimayambitsa kusinthasintha ndi discontinuities mu ntchito voteji / panopa, ndi kusintha pa ntchito panopa komanso kuchititsa harmonic panopa kusinthasintha.

Magawo aukadaulo

Mawonekedwe
● Kupanga zinthu modula, kuchepetsedwa kwambiri kwa voliyumu, kapangidwe kachipangizo, kusankha, kukhazikitsa ndi kugwiritsa ntchito;

Pulatifomu yamphamvu yapakati patatu: Ma DSP awiri oyandama a 32-bit ochokera ku TI ndi FPGA imodzi yochokera ku ALTERA imapanga dongosolo lamphamvu lapakati patatu, lophatikizidwa ndi algorithm yanzeru ya TTA yozindikira ma harmonic ndi kuwerengera kwanthawi zonse. 51, ndi pafupipafupi ntchito akhoza kukhala mkulu monga 150M, amene amaonetsetsa mkulu liwiro ndi zolondola mawerengedwe harmonic kulekana;
● Dongosolo la zitsanzo zakunja zothamanga kwambiri zamakina ambiri: Zophatikizidwa ndi zida zitatu zapawiri-zolowera zothamanga kwambiri za analogi-to-analogi zamitundu 12 (ADS8558) za American TI Company, mpaka ± 10V kuyika kwa analogi, 1.25us sampling cycle , luso lachitsanzo lamphamvu limapangitsa chipangizocho kukhala cholondola, chokhazikika komanso chodalirika cha ntchito;
● Yoyamba kunja mphamvu gawo: Choyambirira kunja EasyPAC-IGBT gawo, utenga m'badwo wachinayi IGB luso, atatu mlingo topology, ali m'munsi inductance kapangidwe ndi m'munsi kusintha kusintha, kusintha pafupipafupi akhoza kufika 30kHZ, ndi voliyumu ndi yaying'ono, The mphamvu kachulukidwe. imawirikiza kawiri, yomwe ndi mwala wapangodya wa hardware kuti akwaniritse APF modular;
● Kuwongolera kwabwino kwa kutentha: kuyang'anira nthawi yeniyeni ya kutentha kwa zipangizo zamagetsi za magawo atatu, kutentha kukadutsa mtengo wa 1, kumangowonjezera kutulutsa, ndipo kutentha kukadutsa mtengo wa 2, kumapereka ndalama zambiri. - Alamu ya kutentha, yodzimitsa yokha ndikuyimitsa chipukuta misozi;
● Algorithm yamphamvu yowongolera: Hongyan Power's modular APF itengera kuwongolera kwathunthu kwa digito, ndipo ma aligorivimu ozindikira omwe amalumikizana ndi ma harmonic amatengera njira yodziwikiratu yodziwika bwino yotengera kusintha kwa domain (pansi-pansi Algorithm), yomwe imatha kulekanitsa mwachangu komanso molondola nthawi yomweyo. mtengo, nthawi yoyankha chipukuta misozi imakhala yabwino kwambiri, ndipo yankho lenileni la 10ms limakwaniritsidwa.Gawo loyang'anira panopa limagwiritsa ntchito ndondomeko yamakono yamakono (PR) yomwe ikuwongolera panopa, yomwe ingatsimikizire kuti nthawi yeniyeni ndi yolondola pakutsata kwamakono;
●Kulumikizana kwabwino kwa makompyuta a anthu: APF ya Hongyan Power ya APF imagwiritsa ntchito skrini ya 5-inch LCD liquid crystal display touch screen.Makina angapo akalumikizidwa mofanana, chitseko cha nduna chimatengera chophimba cha 10-inch.Magawo amtundu wamagetsi monga voteji yamakina, apano, THD, PF amawonekera pang'onopang'ono, ndikuthandizira pa intaneti Kusintha magawo ogwiritsira ntchito, chitetezo cholemera ndi ntchito zowunikira, zosinthidwa bwino ndi malo osiyanasiyana ogwiritsira ntchito;
● Dongosolo lodalirika la kuziziritsa mpweya: Imatengera mtundu wa DC fan, yomwe imakhala yochepa kwambiri yolephera kugwira ntchito mosalekeza, ndipo imakhala ndi ntchito yozindikira zolakwika komanso kuwongolera mwanzeru kuchuluka kwa mpweya, kutengera malo ogwirira ntchito movutirapo, ndikuperekeza kutentha. kuwonongeka kwa chipangizo cha APF!
● Ntchito yoyambira ndi kugona mwanzeru: Pamene ma modules angapo akuyenda mofanana mu kabati, ma modules amadzutsidwa okha kapena ogona molingana ndi kuchuluka kwa katundu.Pamene gawo lokha la ma modules likugwiritsidwa ntchito, dongosololi lidzalamulira ma modules nthawi zonse malinga ndi nthawi yomwe yakhazikitsidwa.Kulowetsa mozungulira, kugona mozungulira.Onetsetsani kuti gawo lililonse likugwira ntchito bwino, sinthani moyo wautumiki ndi mawonekedwe a kutentha kwa zida zonse;
● Yosavuta komanso yofulumira yowunikira ntchito yoyang'anira kutali: Gawo la Hongyan APF litha kukhala ndi ntchito yolumikizirana yakutali, kuti chipangizo chonsecho chizigwiritsidwa ntchito patali kudzera pamafoni am'manja, kusintha magawo ogwiritsira ntchito, kufunsira ntchito, ndi zina. Tumizani zolakwika kuti muthandizire kukonza zida. ndi kasamalidwe, malinga ngati malo a chipangizocho ali ndi chizindikiro cha foni yam'manja, mosasamala kanthu komwe woyang'anira ali, chipangizocho chikhoza kuyang'aniridwa, kusungidwa ndi kuyendetsedwa;
