Електрична частина гідроелектростанції потужністю 60 МВт з агрегатами ВГС 850/110-64 з дослідженням питань експлуатації високовольтних вимикачів

Abstract

In the master's qualification work the electric part of the hydroelectric power plant (HPP) with the capacity of 60 MW is designed. The feasibility study for the design of the HPP has been completed. The calculation of electric load schedules was carried out, the main and auxiliary equipment was selected. Made a choice of the structural scheme of the station, the circuit of an open distribution device (ODD) of 110 kV and the schemes of own needs; switching equipment, bus controllers, measuring transformers, surge suppressors, battery storage. The calculation of the lightning protection of the ODD-110 kV was performed. The main requirements for high voltage switches of electric power stations, and issues of operation and maintenance of high voltage switches are considered. In the section of labor protection the analysis of potentially hazardous and harmful production factors at the power plant has been carried out and the measures of safety of life of personnel in emergency situations have been proposed.
