KONCHILIK KORXONALARINING 0,4 KV KUCHLANISHLI TARMOQLARIDA ELEKTR ENERGIYASINING SIFAT KO‘RSATKICHLARI VA ISROFLARINI EKSPERIMENTAL TADQIQ QILISH
Referat
Maqolada 0,4 kV kuchlanishli konchilik korxonalarining elektr tarmoqlarida elektr energiyasi sifat ko‘rsatkichlari va energiya isroflarini eksperimental tadqiq qilish masalasi o‘rganilgan. Respublikada ishlab chiqarish korxonalari va sexlar sonining ko‘payishi natijasida tarmoqlarda bir yoki uch fazali iste’molchilarning nosimmetrik taqsimlanishi kuzatilmoqda, natijada fazalar nomutanosibligi va yuklama toklarining nosimmetrikligi hisobidan energiya isroflarini 21% gacha oshishiga olib kelmoqda. Tadqiqot jarayonida 0,4 kV kuchlanishli konchilik korxonalari tarmog’ining boshlang‘ich parametrlari, bir chiziqli elektr ta’minoti sxemasi va liniya yuklama toklari aniqlandi. Elektr energiyasi sifatini baholash va isroflar darajasini aniqlash masalasi AR6-analizatori yordamida amalga oshirildi. Eksperiment natijalari kunlik iste’mol, iste’molchi-lar xususiyatlari va elektr energiyasi sifat ko‘rsatkichlari bo‘yicha raqamli ma’lumotlar bazasini shakllantirish imkonini berdi. Energiya isrofiga asosiy ta’sir etuvchi omillar sifatida transformator va elektr iste’molchilar quvvat-larining nomutanosibligi, fazalarning nosimmetrik yuklanishi va o‘zgartiruvchi qurilmalarning yuqori garmonikalarni hosil qilinishi tarmoq sifatiga ta’siri aniqlangan. Shu asosda 0,4 kV kuchlanishli konchilik sanoati tarmoqlarida energiya isroflarini kamaytirish va elektr energiyasi sifatini yaxshilash bo‘yicha chora-tadbirlar ishlab chiqish imkoniyatlari ko‘rib chiqilmogan.
