Abstract

In master's qualification thesis the electric part of hydroelectric power plant with a power of 9 MW is designed. The feasibility study on design of hydroelectric power plant is executed. In electrotechnical part schedules of electric loadings are calculated, the power and service equipment is chosen, the choice of the block diagram of station, the scheme open distribution device of 10 kV and the scheme of own needs is carried out; the switching equipment, a busbar, measuring transformers, means of restriction of retension, the battery, and also calculation of lightning protection and the grounding device for distribution device 10 kV is executed. The influence of the dispersed generation on operation of electricity distribution networks. In the feasibility part of the master's thesis the prime cost of electricity generated in accordance with the current method of calculation is defined. In the section of labor protection the analysis of potentially dangerous and harmful production factors at power plant and safety in emergency conditions is carried out.
