Maqolada o‘zgaruvchan suv talabi va gidravlik sharoitda nasos agregatlarini tanlash qarorlarini avtomatik sarf rostlash bilan muvofiqlashtirish usuli taklif etiladi. Parallel nasoslar guruhi uchun suv balansi, sarf va napor tavsifi hamda elektr quvvati modeli shakllantiriladi. Yuqori boshqarish darajasida agregatlar tarkibi energiya sarfi, sarf topshirig‘i va texnik cheklovlar asosida tanlanadi; quyi darajada texnik jihatdan mos chastotali yuritma PI rostlagich orqali boshqariladi. Modelni yangilash o‘lchov sifati, parametrlarning aniqlanuvchanligi va fizik chegaralar bilan bog‘lanadi. Birinchi tartibli lokal model uchun yopiq kontur barqarorlik shartlari chiqariladi va rostlagich parametrlarini yangilashda boshqaruv signalini uzluksiz saqlash ifodasi keltiriladi. Metodik natija boshqarish darajalari o‘rtasidagi signallar, yangilash shartlari va qiyosiy baholash mezonlarini bir tizimda belgilashdan iborat. Energiya samaradorligini tasdiqlash uchun bir xil suv hajmi va bosim talablaridagi hisoblash hamda laboratoriya sinovlari metodikasi beriladi. Tadqiqot nazariy va metodik xususiyatga ega
