Abstract:
This study presents the conceptual design of a hydroelectric
power plant, as a part of a large scale rehabilitation project for an
existing power plant in Antalya, Turkey. The aim of the
rehabilitation project is to increase the power and efficiency of
the plant and its scope includes CFD aided turbine design, model
production and tests, the design, production and implementation
of the turbine, generator and the SCADA system. This study is
the first attempt, as a preliminary study, to handle the problem
and perform a conceptual design of the hydroelectric power
plant. The existing plant is modeled to estimate the head and flow
rate characteristics at various sections of the system. The net
head and flow rate of the turbine are estimated. Transient
analyses of the system are also performed to evaluate water
hammer characteristics. The results of the transient analyses
provide the inputs for the design of by-pass pipeline and pressure
relief valve. The estimated net head and flow rate from the
simulations are used as inputs for the preliminary design. The
dimensions of the spiral case, the diameter of the stay vanes and
guide vanes, wicket gate heights, runner diameter and rotational
speed, runaway characteristics and preliminary output power are
determined. The best efficiency point and the design point of the
turbine are also obtained as the net head versus the flow rate.
These results provide an idea on the feasibility of the increase in
power.
