Faulty phase selection of transmission lines based on intrinsic mode energy entropy and SVM

By use of EMD the signals sampled in strong noise background of are decomposed and according to the spectrum characteristics of obtained intrinsic mode components the selective filtering is conducted,then the fundamental component in the filtering results is extracted and combining with sine wave parameter method the dielectric loss angle is calculated.

The author applied FEM to analysis natural model and time course response of the leveling machine housing, which is consisted of upper beam as cast entity and other parts as weld structure.

Through numerical calculation,the natural modes and dynamic response of the system can be acquired.

In this paper,the natural mode of the Humen suspension bridge is field obtained with a continuous real time GPS monitoring system.

According to general relativity and principles of interaction,when a revolving system composed of two or more heavenly bodies, revolves around another far heavier heavenly body,such as a star,the relativistic effect produced between them will cause inherent energy change,and thereby the temperature change, in all the heavenly bodies except the star.

In view of system modal power,the expressions of various sub-mode powers were derived from the eigenfunction of a bladed disk in this paper.
