The Calibration Algorithm of Energy Detection and Site Meter

This chapter proposes a kind of caLibration algorithm to capture the number of pulses which aims to the caLibration of the meter field so as to achieve the accurate detection of power. In order to avoid the leakage of spectrum, it samples three-phase AC synchronously with the technology of digital phase-locked frequency multipLication. It describes the method of power correction in detail and decrease the power measurement error caused by additional phase. Results illustrate that the proposed algorithm is correct and effect.
