Mitundu yodziwika bwino ya ma inverter imaphatikizapo: kuyika kwa kiyibodi ya opareta, kuyika ma siginecha olumikizirana, kuyika ma siginecha a analogi, kuyika kwa ma siginecha ndi kuyika kwamachitidwe olankhulirana. Mitundu yoperekedwa pafupipafupiyi imakhala ndi zabwino ndi zovuta zake, chifukwa chake iyenera kusankhidwa ndikukhazikitsidwa malinga ndi zosowa zenizeni. Pakadali pano, mitundu yosiyanasiyana yoperekedwa pafupipafupi imatha kusankhidwa molingana ndi zofunikira zogwirira ntchito ndikusinthira.
Kuwongolera mode
The linanena bungwe voteji otsika voteji ambiri pafupipafupi kutembenuka ndi 380 ~ 650V, mphamvu linanena bungwe ndi 0.75 ~ 400kW, pafupipafupi ntchito ndi 0 ~ 400Hz, dera lake lalikulu utenga ac-dc - ac dera. Kuwongolera kwake kwadutsa mibadwo inayi yotsatira.
Sinusoidal pulse width modulation (SPWM) control mode
Makhalidwe ake ndi dongosolo kulamulira dera ndi losavuta, mtengo ndi otsika, makina khalidwe kuuma ndi zabwino, akhoza kukwaniritsa ambiri kufala yosalala liwiro malamulo pempho, wakhala ankagwiritsa ntchito m'munda uliwonse wa makampani. Komabe, pafupipafupi, chifukwa cha kutsika kwamagetsi, torque imakhudzidwa kwambiri ndi kutsika kwamagetsi kwa stator kukana, komwe kumachepetsa torque yayikulu kwambiri. Kuphatikiza apo, mawonekedwe ake amakina, pambuyo pa zonse, palibe mota yachindunji, ndipo kuwongolera kwamphamvu komanso kosunthika kwa torque sikukhutiritsa, komanso magwiridwe antchito amtunduwu siwokwera, mawonekedwe owongolera amasintha pakulemetsa, kuyankha kwa torque kumachepera. , kugwiritsa ntchito torque yamagalimoto sikukwera, kuthamanga kotsika ndi kukana kwa stator komanso kukhalapo kwa inverter kufa kwanthawi yayitali komanso kuwonongeka kwa magwiridwe antchito, kusakhazikika bwino. Chifukwa chake, anthu adapanga malamulo owongolera ma vector control frequency frequency.
Voltage space vector (SVPWM) control mode
Potengera momwe m'badwo wonse umakhalira wa mawonekedwe a magawo atatu, umapanga mawonekedwe osinthika a magawo atatu nthawi imodzi ndikuyerekeza njira yozungulira yozungulira yozungulira ya mpweya wamagetsi pacholinga chake, ndipo poligoni yodulira mkati imayandikira bwalo. . Pambuyo pogwiritsidwa ntchito pochita, zimasinthidwa, ndiko kuti, kubweza pafupipafupi kumayambitsidwa kuti athetse vuto la kuwongolera liwiro. Chikoka cha kukana kwa stator pa liwiro lotsika chimathetsedwa ndi kuyerekezera kwamawu amplitude yolumikizana ndi flux. Magetsi otulutsa ndi apano amatsekedwa kuti apititse patsogolo kulondola kwamphamvu komanso kukhazikika. Komabe, pali maulalo ambiri mumayendedwe owongolera ndipo palibe kuwongolera kwa torque komwe kumayambitsidwa, chifukwa chake magwiridwe antchito samayenda bwino.
Vector control (VC) mode
Vector control variable frequency speed regulation, ndi stator panopa wa asynchronous motor mu magawo atatu dongosolo Ia, Ib, Ic, kupyolera mu gawo atatu - magawo awiri kusintha, ofanana ndi awiri gawo static coordinates system, ac panopa Ia1Ib1 kachiwiri mwa kukanikiza kusintha kozungulira kozungulira kozungulira, komwe kumafanana ndi ma dc apano a Im1, It1 (Im1 ndi ofanana ndi kusangalatsa kwamagetsi a dc motor; I1 ndiyofanana ndi mphamvu yamagetsi yomwe imagwirizana ndi torque), ndiyeno kuwongolera kuchuluka kwa mota ya dc kumapezeka potengera njira yowongolera ya mota ya dc. Kwenikweni, ac motor ndi yofanana ndi dc motor, ndipo liwiro ndi maginito amayendetsedwa paokha. Zigawo ziwiri za torque ndi maginito zimapezedwa ndikuwongolera kulumikizana kwa rotor flux ndikuwola kwa stator pano. Njira yowongolera vekitala ndiyofunikira kwambiri. Komabe, pakugwiritsa ntchito, kulumikizana kwa rotor flux kumakhala kovuta kuwonedwa molondola, mawonekedwe amachitidwe amakhudzidwa kwambiri ndi magawo amagalimoto, ndipo kusintha kwa vekitala komwe kumagwiritsidwa ntchito pakuwongolera injini yofananira ya dc ndizovuta, kotero zenizeni. kuwongolera zotsatira ndizovuta kukwaniritsa zotsatira zabwino zowunikira.
Direct torque control (DTC) mode
Mu 1985, DePenbrock, pulofesa ku yunivesite ya ruhr ku Germany, adapereka lingaliro loyamba laukadaulo wosintha ma frequency a DTC. Pamlingo waukulu, ukadaulo uwu umathetsa kusowa kwa kuwongolera vekitala, ndipo umakula mwachangu ndi lingaliro lowongolera, dongosolo losavuta komanso magwiridwe antchito abwino kwambiri komanso osasunthika. Ukadaulo wagwiritsidwa ntchito bwino pakutumiza kwamphamvu kwamagetsi amagetsi amagetsi. Direct torque control (DTC) imasanthula mwachindunji masamu ac motor mu stator coordinate system ndikuwongolera kulumikizana kwa maginito ndi torque ya mota. Sichifunikira kuti mota ya ac ikhale yofanana ndi mota ya dc, chifukwa chake imapulumutsa mawerengedwe ovuta kwambiri pakusintha kwa vector. Sichiyenera kutsanzira kuwongolera kwa dc motor, komanso sikuyenera kufewetsa masamu a ac motor kuti adutse.
Mphambano wa Matrix - control intersection
Kutembenuka kwafupipafupi kwa VVVF, kutembenuka kwa mafupipafupi a vekitala ndi kutembenuka kwafupipafupi kwa torque zonse ndi ac - dc - ac frequency kutembenuka. zolakwa zake wamba ndi otsika athandizira mphamvu chinthu, lalikulu harmonic panopa, lalikulu dc dera amafuna lalikulu mphamvu yosungirako capacitor, ndi mphamvu zongowonjezwdwa sangathe kudyetsedwa mmbuyo ku gululi, ndiko kuti, sangathe kugwira ntchito zinayi quadrant. Pachifukwa ichi, kutembenuka kwa matrix ac-ac frequency kunayamba. Chifukwa cha kutembenuka kwa matrix ac-ac frequency kumasunga ulalo wapakati wa dc, motero amapulumutsa voliyumu yayikulu, yokwera mtengo ya electrolytic capacitor. Ikhoza kukwaniritsa mphamvu ya l, sinusoidal athandizira panopa ndipo akhoza kuthamanga mu quadrants anayi, mphamvu kachulukidwe dongosolo ndi lalikulu. Ngakhale kuti lusoli silinakhwime, limakopabe akatswiri ambiri kuti aphunzire mozama. Chofunikira chake sichiri chowongolera pakali pano, chofanana ndi maginito, koma torque ndiyomwe imayendetsedwa kuti ikwaniritse. Njira yeniyeni ndi:
1. Yang'anirani kulumikizana kwa stator flux poyambitsa stator flux monitorer kuti muzindikire kuthamanga kwa sensorless;
2. Chizindikiritso chodziwikiratu (ID) chizindikiritso chodziwikiratu cha magawo agalimoto kutengera mtundu wolondola wamasamu wagalimoto;
3. Mawerengeredwe enieni ogwirizana ndi stator impedance, mutual inductance, magnetic saturation factor, inertia, ndi zina zotero. Kuwerengera torque yeniyeni, stator flux linkage ndi liwiro la rotor kuti muwongolere nthawi yeniyeni;
4. Zindikirani chizindikiro cha PWM chopangidwa ndi kayendetsedwe ka band-band ndi kugwirizanitsa maginito ndi torque, ndikuwongolera kusintha kwa inverter.
Muyenera kuwongolera mota ndi inverter yokha
1) chiwerengero cha mitengo ya injini. Nambala yagalimoto yanthawi zonse siyoposa (yoyenera kwambiri, apo ayi mphamvu ya inverter idzawonjezeka moyenerera.
2) mawonekedwe a torque, torque yovuta komanso ma torque othamanga. Pankhani ya mphamvu yamagalimoto yomweyo, yokhudzana ndi kuchuluka kwa torque yayikulu, mawonekedwe a inverter amatha kusankhidwa.
3) Kugwirizana kwamagetsi. Pofuna kuchepetsa kusokonezeka kwa magetsi akuluakulu, riyakitala ikhoza kuwonjezeredwa mu dera lapakati kapena gawo lothandizira la inverter, kapena thiransifoma yodzipatula ikhoza kukhazikitsidwa. Nthawi zambiri, mtunda wapakati pa mota ndi chosinthira pafupipafupi ukupitilira 50m, cholumikizira, fyuluta kapena chingwe choteteza chishango chiyenera kulumikizidwa pakati pawo.
Matrix ac-ac frequency conversion ali ndi kuyankha kwa torque mwachangu (<2ms), kulondola kwambiri (± 2%, palibe mayankho a PG), komanso kulondola kwa torque (<+3%). Nthawi yomweyo, ilinso ndi torque yayikulu komanso yolondola kwambiri, makamaka pa liwiro lotsika (kuphatikiza liwiro la 0), imatha kutulutsa 150% ~ 200% torque.
Sankhani mtundu wa inverter, malinga ndi mtundu wa makina opanga, liwiro la liwiro, kulondola kwa liwiro lokhazikika, kuyambira makokedwe, adaganiza zosankha njira yoyenera kwambiri yoyendetsera inverter. Zomwe zimatchedwa zoyenera ndizosavuta kugwiritsa ntchito, komanso zachuma, kuti zikwaniritse zofunikira ndi zofunikira za ndondomeko ndi kupanga.
