摘要：
With the rapid development of new electric load, the power quality of power supply system put forward higher requirements. For the problem of the multi-disturbance complex power quality signal, the paper presents a multi-disturbance complex power quality signal HHT detection method, using Hilbert-Huang transform (HHT) time-frequency analysis on the multi-disturbance complex power quality signal. This paper introduced the basic principle of HHT; put forward to use HHT method to achieve the complex power quality signal detection; analysed of the superiority of HHT in the complex power quality signal detection. The simulation results show that this method can be a real-time accurate detection of disturbance's starting and ending time and disturbance's amplitude, and applicable to the detection and identification system of the multi-disturbance complex power quality signal.
摘要：
In this paper, a data fusion approach based on compressed sensing theory for energy-efficient data transmission in wireless sensor networks is proposed. This approach can effectively reduce the data transmission cost and improve data precision. The simulation results show the feasibility and effectiveness of the proposed approach.
