Annotatsiya. Kirish. Respublikamizda iqtisodiy tarmoqlarning rivojlanishi, aholi turmush darajasining o‘sishi va sonining ko‘payishi natijasida energiyaga bo‘lgan talab ortib bormoqda. Bu holat ijtimoiy va iqtisodiy sohaning rivojlanishiga, jumladan, mamlakatning qishloq xo‘jaligi sektorini elektr energiyasi bilan ta’minlash darajasiga katta ta’sir ko‘rsatmoqda. Ushbu ta’sirlarni bartaraf etishning asosiy yechimlaridan biri sifatida, qayta tiklanadigan energiya manbalari asosida ishlaydigan energiya qurilmalarini, xususan, kichik quvvatli gidroelektr stansiyalarini rivojlantirish va samaradorligini oshirish yetakchi o‘rinlardan birini egallaydi.

Usul va materiallar. Maqola qishloq xo‘jaligida ishlatiladigan nasos agregatlaridan chiqqan suv oqimlariga moslashtirilgan 3 kVt quvvatga ega ikki rotorli gidroenergiya qurilmasini Matlab/Simulink dasturiy paketidan foydalanib modellashtirilgan.

Natijalar. Nazariy va eksperimental tadqiqotlar natijasiga ko‘ra, yo‘naltiruvchi apparatning geometrik o‘lchamlari quyidagicha aniqlangan: tashqi diametri 1 m, ichki diametri 0,5 m, yo‘naltiruvchi pichoqlar soni 16, yo‘naltiruvchi qanotlarning o‘rnatish burchagi β= -17,50, pichoqlarning diametri 0,5 m, vtulka diametri 0,2 m, pichoqlar soni 6, pichoqlarning optimal o‘rnatish burchagi 202,50 va suv sarfining maksimal qiymati 0,24 m³/s. Mikro gidroelektr stansiyasining nominal quvvati 3 kVt ekanligi aniqlangan.

Xulosa. Qurilmaning texnik va iqtisodiy ko‘rsatkichlari tahliliga ko‘ra, ishlab chiqilgan 3 kVt quvvatga ega vertikal o‘qli mikro gidroelektr stansiyasining amaliy qo‘llanilishi natijasida bir yilda o‘rtacha 19500 kVt·soat elektr energiyasi ishlab chiqarish, 14,53 tonna shartli yoqilg‘i tejash va 28,5 tonnadan ortiq karbonat angidrid (CO₂) chiqindilarining atmosferaga chiqishining oldini olish mumkin. Ushbu mikro-gidroelektr stansiyasining iqtisodiy samaradorligi “Sof joriy qiymat” (SJQ) usuli yordamida baholangan bo‘lib, unda sof joriy qiymat 5500 AQSh dollariga teng, statik qaytarish davri 1,56 yil va dinamik qaytarish davri 2,78 yilni tashkil qiladi.
