Small Hydro Power (SHP) development is being increasingly undertaken all over the world, especially in the developing countries, because of their various merits, varied application, and flexibility of utilization. Handling of large hydropower-generating units and keeping the size of the turbine generator sets are economically beneficial, which require higher running speeds and results in greater pressure differences between the two sides of the vanes of a turbine runner. These forces also cause vibrations of the stator, which are transmitted through the frame to any adjoining structure and causes damage to the bearing, stator, and rotor winding as well as reduces the lifetime of the entire machine. Furthermore, cavitations due to discharge cause the major vibration effects in most of the hydroelectric power plants. With modified Concrete support in the stay column, a smooth operation of the turbine generator sets can be achieved. |
