THE INFLUENCE OF OPERATION CONDITIONS OF HYDROELECTRIC POWER PLANTS THE CHOICE OF THE MAIN PARAMETERS OF THE SUCTION PIPES

Abstract

Considered run-of-river hydropower plants (HPP). Notes the importance of technical-economic calculations in the justifi cation of large water-conducting elements of the path these types of HPP. The methodology of economic substantiation of the expediency of increasing the length of the draft tube. Using the technique of the calculations for lowpressure hydroelectric run-of-river type. The results of the analysis of the influence of the operating conditions of the hydroelectric power station on basic geometrical parameters of draft tube.
