Automatic Identification of Shaft Orbits of Generator Sets Based on Improved Moment Invariant
Ni Chuan · Electric Power Science and Engineering · 2004
Axis orbit is an important characteristic to be used to diagnose the condition of the generator sets. Moment invariant of Hu is one of the important tools in graphic recognition. In this paper the limit of moment invariant in disperse state is analyzed and the method is improved. Simulation experiment of automatic identification for some typical axis orbits are operated, which proves that the method is effective, brief and feasible.
