Analysis and compensation of active power measurement error caused by non-integer period sampling
International Journal of Smart Grid and Clean Energy
A software compensation method is proposed in this paper to reduce the active power measurement error which is caused by non-integer period sampling in the electrical energy measurement process. In the process of electrical energy measurement, the sampling frequency is fixed, and it is an integer multiple of the standard frequency. When the grid frequency fluctuates, the real-time frequency deviates from the standard frequency, therefore, the sampling rate is not strictly the integer multipledoi:10.12720/sgce.4.1.65-71 fatcat:wfwdpox77zet7o3lh6yyzgegtm
