Abstract

Penstock is a closed conduit waterway which conveys water from intake to power house. The optimum diameter of penstock is determined through the optimization between the cost associated with friction head loss and the material & installation cost of penstock. Head loss cost itself depends on power purchase cost, project life and average hours of operation of the power plant and other parameters. This paper first reviews the existing empirical and analytical methods to determine the economical diameter of penstock. Then a simplified arrangement is developed in Ms Excel where the material cost, the cost associated with the head loss in penstock and other parameters which may influence these costs can be analyzed. These costs are plotted in graph and the optimum diameter is calculated graphically. Finally the major parameters affecting the optimum diameter of penstock are identified. It was found that the tariff and material, installation and maintenance cost of penstock are the vital parameters which play the major role during optimization of penstock.
