Research of the Demodulation for TWACS Based on the Industrial Power Lu Wenbing, Sun Fengjie, Luo Yingli, Yan ying , Liu Zhijun, Bi Xiaowei, Li Pengfei, ChenYongquan The College of Electric and Electronic Engineering, North of China Electric Power University, Beijing in China jiaoshijie@vip.sina.com Keywords: TWACS;industrial power;time-frequency analysis;Wigner-Ville Distribution;short-time Fourier transform;cross-correlation technique.
The noise of the interference of industrial power grid is much stronger than of the civil power grid, SNR is low while demodulating signals in industrial power ,so the voltage zero-crossing time difference have more influence than in civilian power grid. 4 Conclusion The experiments and simulations proved that this communication performance can adapt to channel conditions of industrial distribution,meanwhile can automatically adapt to all kinds of connections of the distribution transformer.
