Електрична частина гідроелектростанції потужністю 12,8 мВт з агрегатами типу ВГС 325/64-18 з дослідженням питань обслуговування електричних машин

Abstract

In the master's qualification work the electric part of the hydroelectric power plant (HPP) with the capacity of 12,8 MW is designed. The feasibility study for the design of the hydroelectric power station has been completed. In the electrical part the calculation of electric load schedules was made, power and auxiliary equipment were selected, made a choice block diagram of the station scheme open distribution device (ODD) 10 kV circuits and their needs; switchgear, stub, instrument transformers, surge limitation means, battery, and has been calculated and lightning grounding device ODD 10 kV. The issue of servicing electrical machines has been investigated. In the section of the labor protection, an analysis of the working conditions during the work related to the maintenance of generators of the hydroelectric power station was carried out, the parameters of the earthing device of the ODD 10 kV were proposed, and the main measures of fire protection of hydroelectric power stations were described.
