Research on Active Power Test for AC Power Based on Correlation Analysis

XIAO Ji-xue,YANG Yu,WANG Kai,LI Shi-xi (School of Mechanical Engineering and Automation,Xihua University,Chengdu 610039 China)  
For AC power smart sensor,the active power test method based on correlation analysis is proposed.It is analyzed and compared with traditional parameterized-definition test approach.The results indicate that the correlation analysis method can effectively reduce the impact of interference in the power signal on test precision,and the system simplification,cost reduction and improvement of test performance such as real-time are resulted in the absence of any additional overhead in hardware and computing time.Experiments results show that compared to the traditional parameterized-definition test means,the correlation-based method can reduce the number of the sample data for power analysis by about 70% and the noise amplitude can be permitted from 3% to about 12% of signal amplitude.
