Procedure Selecting Pumps Running as Turbines in Micro Hydro Plants

Cavitation Inception in Crossflow Hydro Turbines

Cavitation is a common flow phenomena in most hydraulic turbines and has the potential to cause vibration, blade surface damage and performance loss. Despite the fact that crossflow turbines have been used in small-scale hydropower systems for a long time, cavitation has not been studied in these turbines. In this paper, we present the findings of a computational study on cavitation inception i...

Optimal design of axial hydro turbine for micro hydropower plants

In our country we have enormous low head potation flows in agricultures and aquacultures with almost fix flow rates that can be used as micro hydro power plants for producing energy. But the main problem is the high capital price per kW. Therefore there is needed to design a simple machine with a good runner for covering the various potential flows. In this paper an axial hydro turbine has desi...

Modeling Hydro Power Plants and Tuning Hydro Governors as an Educational Guideline

Appropriate modeling of components and related controllers are very significant in studying dynamic performance of power systems. In this paper, an educational procedure for modeling, simulation, and governor tuning of hydro power plants is presented. Different existing dynamic models of hydro plant components are reviewed. The procedure for calculating the required parameters from real plant d...
