Abstract

This chapter describes technology that ensures reliable pumping of drainage and sewage water during electromechanical and hydro-mechanical transients from blocks of the hydroelectric power stations and pumping stations. As an alternative source of energy, it is proposed to use the energy of the liquid column of the pressure penstock of the stations, and as an auxiliary, to use jet pumps. Transmission of energy to the suction stream is carried out without direct usage of electrical and mechanical energy. During total shutdown of electric power, reliable evacuation of drainage and seepage water and reduction the influence of electromechanical and hydro-mechanical transients on power equipment and pipelines can be ensured with the use of self-regulating jet pumps over a period of several days; this cannot be accomplished by any other pump. The scientific results of the research are recommended to allow efficient use of water and energy resources and to ensure reliable operation of the power equipment of stations, especially in the events of sudden power outages.
