68 4.5. Elektr jixozlarni loyixlashda hisoblash Ko‘pincha kondensator qurilmalari parametrlari loyihalash bosqichida hisoblanadi. Ana’naviy usulda hisoblash (elektr energiyani o‘lchagichlarga asosan) imkoni yo‘q. Bo‘nday xollarda kondensator batareyalar tarkibiy tizimlari, uning quvvati taxminan pasaytiruvchi transformatorning (YuK/PK) mos keladigan nominal quvvatining 25% ni tashkil qiladiganini ulash tavisiya qilinadi. Misol. Transformator 1000 kVA => Q kondensatorlar = 250 kVAr. Eslatma. Bunday o‘zaro nisbatlari quyidagi shartlarga to’g‘ri keladi: - transformator quvvati 1000 kVA - transformator ning amaldagi yuklanishi = 75% - amaldagi yuklamalar cosφ = 0,80} (K - qiymatini 5.2 –jadvaldan qarang, K= 0,421) - talab qilinadigan cosφ = 0,95} Agar iste’molchining quvvati kVt da, berilgan bo‘lsa, u holda kondensatorlarning quvvatini hisoblash uchun 5.2- jadvaldan K ning kerakli qiymatini topish mumkin. Bundan tashqari, jadvalda cosφ ning qiymatlari va ularga mos tgφ qiymati keltirilgan.
