During the overhaul period of steam turbine in some plant, the blades’ vibrational security had been analyzed through the stationary frequency on the spot from the blades by using spectrum analyzer of Nanjing trued software engineering co., Ltd. The results of the test showed the turbine’s blades of next to last stages (stage groups) were safe when they were in operation with the working rotating speed.
