Study on Centrifugal Force on the Long Last Stage Blade of the Large Steam Turbine 300 MW

The aim of this paper is to present the capabilities of the centrifugal force acting on the long blade of the last stage of the large steam turbine 300 MW. Now-a-days, in the thermal power plants in Viet Nam, the turbine'soperation depends on the manufacturing documents, but not enough for all operational situations. The blade is one of the important parts of turbine that its endurance influences directly the operation and safety of turbine, but blade's incidents on operation are entirely possible however happening, the ability replacing these blades by vietnamese manufacturer iscompletelyunforeseen. Therefore, the simulation of the effect of force on the blade in the operating modes corresponding to the forces acting on the blades is very necessary. The process of simulation is presented in detail for  15% the nominal operation for references
