ANALYSIS OF PARAMETERS OF MICRO-HEDP HYDROPOWER
Abstract. In this article, recommendations for the development and research of devices selected for the power of microwaves are given.
Keywords. Micro hydro, power, water flow, energy parameters, nominal power, efficiency, energy consumption.
Zamonaviy sharoitda birinchi navbatdagi vazifalardan bin RES (qayta tiklanadigan energiya manbalari) negizida elektr stansiyalarining raqobatbardoshligini umuman oshirishga qaratilgan chora-tadbirlar majmuasini amalga oshirish, shuningdek, MikroGES va ularning kombinatsiyalaridan foydalanishning ilg'or texnologiyalarini aniqlashdan iborat. ulardan muayyan hududda foydalanish iqtisodiy, texnik va ijtimoiy jihatdan asoslanadi.
Shu bilan birga, qayta tiklanadigan energiya manbalaridan foydalanish hududning muhandislik infratuzilmasini rivojlantirish yo'nalishlarini belgilab beruvchi va belgilangan vazifalarni hal etish yo'llarini ko'rsatuvchi hududni barqaror rivojlantirish dasturining organik va zarur elementi sifatida qaraladi. muammolar.

Shunday qilib, energetika muammosi va uni hal etish uchun muqobil energiya manbalarini jalb etish zarurligi O'zbekiston Respublikasi Prezidentining "Muqobil energiya manbalarini yanada rivojlantirish chora-tadbirlari to'g'risida"gi qarorida qayd etilgan. Olingan ifoda har qanday shakldagi energiya ekstensivlik va intensivlik omillari mahsulotiga mutanosib bo'lgan ma'lum fizik tamoyillarga mos keladi. Bunda H bosimi suyuqlikning intensivlik koeffitsienti yoki energiya intensivligining ko'rsatkichi, suv hajmi W kenglik omili yoki energiya iste'molining miqdoriy ko'rsatkichidir.
Suv oqimining energiya quvvati zichligi Ew Ew = pw*Qw*Vw2 /(2*S) = pw*Vw3 /2, kW/m2 pw - suvning zichligi; Qw - suv iste'moli (Qw = S * Vw); Vw - suv tezligi;
S - suv oqimining ko'ndalang kesimi maydoni. Suv energiya oqimining kuchi Nw ga teng NW = Ew*S = S* pw*Vw3 /2 (2.59) GESlarning energiya parametrlari
Mikro GESning chiqish quvvati (iste'molchiga o'tkaziladigan quvvat) teng ЯМГЭС = ОТ*лП = NW*^T*^n(2.60) bu erda NT - turbina quvvati;
^P- samaradorlik energiyani turbinadan iste'molchiga o'tkazish (generatordagi mexanik yo'qotishlar va yo'qotishlar hisobga olinadi)

Biroq, agar qayta tiklanadigan energiya manbalarini etkazib berish rejimlari va yuklanish jadvallari sezilarli darajada mos kelmasa, o'rta quvvatli Gidroelektrostansiyasi talab qilinishi mumkin va shunga mos ravishda ushbu qayta tiklanadigan energiyaga asoslangan elektr stantsiyasining nominal quvvati uchun katta zaxira bo'lishi kerak. energiya manbai. Shu munosabat bilan, qayta tiklanadigan energiya manbalarining har bir turi uchun alohida elektr stansiyalaridan tashkil topgan bir nechta qayta tiklanadigan energiya manbalariga
asoslangan MikroGES qurilmalar taklif etiladi. Ma'lumki, elektr stantsiyalarining parametrlarini tanlashning asosiy mezonlari energiya va ishlab chiqarilgan energiyaning narxidir. Xuddi shu mezonlar, pirovardida, belgilangan yuk sharoitlari ta'minlangan holda, MikroGES elektr stantsiyalari, shu jumladan kombinatsiyalanganlar uchun asosiy hisoblanadi
