2、han Kahraman, Halit Lt Ycel, Yahya Tagin Abstract Turbine faults in hydroelectric power plants not only reduce the operation time of the plant, but also cause a serious loss of income. One of the most important turbine faults is the turbine wheel wear caused by the cavitation and accordingly the oth
3、er machine equipment faults which cause excessive vibration. In this study, cavitation intensity that the turbines have been exposed in operating conditions has been investigated. As a result of the calculations, optimum working conditions of the units have been determined with graphs obtained in va
4、rious operating condi- tions. The obtained data can be easily applied to all hydroelectric power plants exposed to ca- vitation, and safe operating conditions can be determined. Keywords: Cavitation; Hydroelectric power plant ;Turbine wheel 1. Introduction Hydroelectric power plants are the most imp
5、ortant renewable energy source of the worlds electricity supply, due to low environmental impacts and low operating and maintenance costs. Hydraulic power has many potentials that have not been used yet. Hydroelectricity is one of the most sustainable sources of clean energy that is best suited to e
6、nvironmental legislation such as Kyoto Protocol. Hydroelectric power plants do not produce greenhouse gas emissions because they do not use fuel and pollute the air. They contribute prevention actions against global warming About 16% of the worlds electricity production is provided by hydroelectric power 1. Hydroelectric power plants do not pollute the environment as much as thermal power plants. But as the dam site is ooded, changes in the surrounding area can take place. In
