Uch fazali asinxron motorlarning nosimmetrik ish rejimlarida faoliyat yuritishi ularning texnik holati, energiya
samaradorligi va ekspluatatsion ishonchliligiga sezilarli ta’sir ko‘rsatuvchi muhim omillardan biri hisoblanadi. Elektr ta’minoti
tizimlarida fazalararo kuchlanish nosimmetriyasi hamda yuklamalarning notekis taqsimlanishi kuzatiladigan sharoitlarda
motorlarning barqaror va samarali ishlashini ta’minlash dolzarb ilmiy-amaliy vazifalardan biridir. Mazkur tadqiqotning
maqsadi nosimmetrik ish rejimlarida asinxron motorlarni nazorat qilish va boshqarish tizimlari eksperimentlarini amalga
oshirish uchun zamonaviy eksperimental metodikani ishlab chiqishdan iborat.
Tadqiqot doirasida uch fazali asinxron motor asosida laboratoriya eksperimental stendi shakllantirilib, faza kuchlanishlari,
toklar, aylanish tezligi, harorat hamda energiya ko‘rsatkichlarini real vaqt rejimida monitoring qilish yondashuvi ishlab
chiqildi. Nosimmetriya darajasini baholashda simmetrik tashkil etuvchilar usuli va kuchlanish nosimmetriyasi koeffitsiyenti
asosida kompleks tahlil amalga oshirildi. Shuningdek, aniqlangan nosimmetriya darajasiga mos ravishda ogohlantirish
hamda himoya boshqaruv qarorlarini shakllantirishga xizmat qiluvchi algoritmik yondashuv taklif etildi.
Ishlab chiqilgan eksperimental metodika nosimmetrik rejimlarning asinxron motorlarning samaradorligi, qizish jarayonlari
va energiya ko‘rsatkichlariga ta’sirini aniq baholash imkonini beradi. Natijalar sanoat elektr yuritmalarida monitoring, diagnostika
va himoya tizimlarini yanada takomillashtirish, ularning ishonchliligi va energiya samaradorligini oshirish uchun
amaliy asos bo‘lib xizmat qilishi mumkin.
