This essay analyzes the halts of the bearing vibration during the process of the impact rotations and speed increments in the cold starts of the steam turbine in the startup debugging of the first IO00MW unit in a power plant. Besides, this essay extracts effective measures from the experiences in its operation to ensure its economical and secure operation as well as providing reference for both prevention and solutions to similar problems in similar units. These measures and solutions turn out right and feasible in practice.
