Annotatsiya
Maqolada uch fazali elektr tarmoqlarida kuchlanish nosimmetrikligini monitoring qilish uchun mo‘ljallangan ochiq kodli ikki avlodli K2U-Node qurilmasini ishlab chiqish va validatsiya qilish metodikasi bayon etilgan. Kuchlanish nosimmetrikligining teskari ketma-ketlik koeffitsiyentini (K₂U) faqat faza kuchlanishlarining ta’sir etuvchi qiymatlari asosida aniqlashdagi nazariy cheklovlar tahlil qilingan. ESP32 va uchta PZEM-004T v3.0 moduli asosidagi Gen-1 qurilmasi kuchlanish nosimmetrikligini dastlabki skrining va taqsimlangan monitoring qilish uchun taklif etilgan. ATM90E32AS mikrosxemasiga asoslangan Gen-2 qurilmasida esa faza kuchlanishlarining amplitudasi va faza burchaklarini o‘lchash orqali simmetrik tashkil etuvchilar hamda K₂U koeffitsiyentini kompleks shaklda hisoblash imkoniyati yaratilgan. Hisoblash misollari faza kuchlanishlari amplitudalari teng bo‘lgan holatlarda ham burchak nosimmetrikligi sezilarli K₂U qiymatini yuzaga keltirishi mumkinligini ko‘rsatdi. Uch bosqichli kalibrlash va validatsiya metodikasi ishlab chiqilgan, shuningdek, GOST 32144-2013 va IEC 61000-4-30 talablariga muvofiq 10 daqiqalik agregatsiya tamoyillari amalga oshirilgan. Taklif etilgan yechim ko‘p nuqtali elektr energiyasi sifatini monitoring qilish, nosimmetriklik manbalarini aniqlash va taqsimlangan energetika obyektlarining texnik holatini baholash uchun istiqbolli hisoblanadi.
