Mode inverter frekuensi umum umume kalebu: setelan keyboard operator, setelan sinyal kontak, setelan sinyal analog, setelan sinyal pulsa lan setelan mode komunikasi. Mode frekuensi sing diwenehake duwe kaluwihan lan kekurangan dhewe, mula kudu dipilih lan disetel miturut kabutuhan sejatine. Kangge, mode frekuensi sing diwenehake beda bisa dipilih miturut kabutuhan fungsional kanggo numpuk lan ngoper.
Mode kontrol
Tegangan output konversi frekuensi umum voltase kurang yaiku 380 ~ 650V, tenaga output yaiku 0.75 ~ 400kW, frekuensi kerja yaiku 0 ~ 400Hz, sirkuit utamane nggunakake sirkuit ac-dc - ac. Mode kontrol kasebut ngalami patang generasi ing ngisor iki.
Mode kontrol modulasi lebar puluhan sinusoidal (SPWM)
Karakteristik yaiku struktur sirkuit kontrol sing gampang, biayane murah, kekerasan karakteristik mekanik uga apik, bisa nglegakake panjaluk regulasi kacepetan transmisi umum, wis digunakake ing saben industri. Nanging, kanthi frekuensi sing kurang, amarga voltase output sing kurang, torsi kasebut kena pengaruh banget karo penurunan voltase resistensi stator, sing nyuda torsi output maksimum. Kajaba iku, sifat mekanik, sawise kabeh, ora ana motor langsung, lan kinerja kontrol kecepatan torsi statis lan dinamis ora memuaskan, lan kinerja sistem ora dhuwur, kurva kontrol ganti beban, respon torsi alon , tingkat panggunaan torsi motor ora dhuwur, kacepetan kurang karo resistensi stator lan anane efek wektu mati inverter lan degradasi kinerja, stabilitas sing kurang. Mula, masarakat nggawe regulasi kecepatan frekuensi variabel kontrol vektor.
Mode kontrol vektor ruang voltase (SVPWM)
Ing premis efek generasi sakabehe bentuk gelombang telung tahap, ngasilake bentuk gelombang modulasi telung fase sekaligus lan nyedhaki trek medan magnetik sing muter bunder sing ideal kanggo jurang udara motor kanggo tujuan kasebut, lan poligon pemotong batin nyedhaki bunder . Sawise digunakake ing praktik, luwih apik, yaiku ganti rugi frekuensi kanggo ngilangi kesalahan kontrol kacepetan. Pengaruh resistensi stator kanthi kacepetan sithik diilangi kanthi estimasi umpan balik saka amplasi link flux. Voltase output lan arus minangka loop tertutup kanggo nambah akurasi lan stabilitas dinamis. Nanging, ana akeh link ing sirkuit kontrol lan ora ana regulasi torsi sing dilebokake, mula kinerja sistem kasebut ora bisa didandani kanthi dhasar.
Mode kontrol Vektor (VC)
Kontrol kecepatan frekuensi variabel kontrol Vector, yaiku arus stator motor asinkron ing sistem telung tahap Ia, Ib, Ic, liwat telung fase - transformasi rong fase, padha karo sistem koordinat statis loro fase, lan AC saiki Ia1Ib1 maneh kanthi menet transformasi rotasi berorientasi lapangan rotor, padha karo koordinat puteran sinkronisasi dc saiki Im1, It1 (Im1 padha karo arus eksitasi motor dc; It1 padha karo arus armature sing sebanding karo torsi), lan banjur jumlah kontrol motor dc dipikolehi kanthi niru cara kontrol motor dc. Intine, motor ac padha karo motor dc, lan kacepetan lan medan magnet dikontrol kanthi mandiri. Rong komponen torsi lan medan magnetik dipikolehi kanthi ngontrol hubungan flux rotor lan arus stator bosok. Metode kontrol vektor duwe teges nggawe jaman. Nanging, ing aplikasi praktis, sesambungan fluks rotor angel ditrapake kanthi akurat, karakteristik sistem kena pengaruh banget karo paramèter motor, lan transformasi rotasi vektor sing digunakake ing proses kontrol motor dc padha, dadi kompleks, mula nyata efek kontrol angel entuk asil analisis sing ideal.
Mode kontrol torsi langsung (DTC)
Ing taun 1985, DePenbrock, profesor ing universitas ruhr ing Jerman, pisanan ngusulake teknologi konversi frekuensi DTC. Nganti akeh, teknologi iki ngatasi kekurangan kontrol vektor, lan berkembang kanthi cepet kanthi ide kontrol novel, struktur sistem sing sederhana lan kinerja dinamis lan statis sing apik banget. Teknologi kasebut wis sukses digunakake ing transmisi ac daya tarik daya tarik lokomotif listrik. Kontrol torsi langsung (DTC) langsung nganalisa model matematika motor ac ing sistem koordinat stator lan ngontrol hubungan magnetik lan torsi motor. Ora perlu motor ac padha karo motor dc, mula bisa ngirit akeh petungan rumit ing transformasi rotasi vektor. Sampeyan ora prelu niru kontrol motor dc, uga ora kudu nyederhanakake model matematika motor ac kanggo decoupling.
Persimpangan matriks - kontrol prapatan
Konversi frekuensi VVVF, konversi frekuensi kontrol vektor lan konversi frekuensi kontrol torsi langsung kabeh konversi frekuensi ac - dc - ac. Kekurangane umume yaiku faktor daya input sing kurang, arus harmonik gedhe, sirkuit dc gedhe mbutuhake kapasitor panyimpenan energi sing akeh, lan energi sing bisa dianyari ora bisa dipas maneh menyang jaringan, yaiku ora bisa nindakake operasi papat kuadran. Amarga alasan iki, konversi frekuensi ac - ac matriks ana. Minangka asil konversi frekuensi matrik ac-ac nyimpen tautan dc tengah, mula ngirit volume akeh, kapasitor elektrolitik sing larang. Bisa entuk faktor daya l, arus input sinusoidal lan bisa mlaku ing patang kuadran, kerapatan daya sistem gedhe. Sanajan teknologi kasebut durung diwasa, isih bisa narik akeh sarjana kanggo nyinaoni kanthi jero. Intine dudu arus kontrol ora langsung, padha karo tautan magnetik, nanging torsi langsung minangka jumlah kontrol sing bisa dipikolehi. Cara khusus yaiku:
1. Kontrol tautan fluks stator kanthi ngenalake pengamat fluks stator kanggo mujudake mode tanpa sensor kacepetan;
2. Identifikasi otomatis (ID) identifikasi otomatis paramèter motor adhedhasar modhel matématika motor sing akurat;
3. Ngetung angka nyata sing cocog karo impedansi stator, induktansi bebarengan, faktor saturasi magnetik, inersia, lan liya-liyane. Hitung torsi nyata, tautan fluks stator lan kecepatan rotor kanggo kontrol wektu nyata;
4. Élingake sinyal PWM sing digawe dening kontrol band-band kanthi tautan magnetik lan torsi, lan kontrol kahanan switching inverter.
Kudu ngontrol motor lan inverter dhewe
1) nomer cagak motor. Nomer motor umum ora luwih saka (cocog banget, yen kapasitas inverter bakal ditambah kanthi pas.
2) ciri torsi, torsi kritis lan torsi akselerasi. Ing kasus daya motor sing padha, tinimbang mode torsi kakehan sing akeh, spesifikasi inverter bisa dipilih.
3) kompatibilitas elektromagnetik. Kanggo nyuda gangguan pasokan listrik utama, reaktor bisa ditambahake ing sirkuit menengah utawa sirkuit input saka inverter, utawa trafo pra-isolasi bisa dipasang. Umume, yen jarak antarane motor lan konverter frekuensi luwih saka 50m, kabel proteksi reaktor, filter utawa tameng kudu disambungake ing tengah-tengahe.
Konversi frekuensi ac-ac matrik duwe respon torsi cepet (<2ms), akurasi kecepatan tinggi (± 2%, ora ana umpan balik PG), lan akurasi torsi dhuwur (<+ 3%). Sanalika, uga torsi wiwitan sing dhuwur lan presisi torsi dhuwur, utamane kanthi kacepetan kurang (kalebu 0 kacepetan), bisa ngetokake torsi 150% ~ 200%.
Pilih jinis inverter, miturut jinis mesin produksi, kisaran kacepetan, akurasi kacepetan statis, torsi wiwitan, mutusake milih mode kontrol inverter sing paling cocog. Sing diarani cocog iku gampang digunakake, nanging uga ekonomi, kanggo nyukupi kahanan dhasar lan syarat proses lan produksi.
