Hydraulic model studies of a hydroelectric unit under operating conditions at hydroelectric/state area hydroelectric plants
Conclusions The trend toward convergence of optimal efficiency zones with respect to reduced rotational speed with decreasing$$n_{s_p } $$ is confirmed.Reverse flows in the zone between the impeller and guide apparatus and prior to the impeller determine the low level of efficiency and significant instability during the operation of a turbine with a PLG 15/984 impeller in the pump mode.The effect of eddy formation and air entrapment from the surface of the tailrace on the power curve of a horizontal capsule unit in the pump mode is manifested when the depth of the impeller axis is less than 1.$ 2D_{1} $.
