Abstract:In the previous work on three-phase circuit instantaneous reactive power theory, harmonic detection method has difficulty coordinating with precision and response speed. The performance of digital harmonic detection strongly depends on low-pass-filter (LPF) capability. The adaptive filter has the characteristics of fast response and low detected precision, while moving-average filter (MA-FIR) with high detection precision and slow response. This paper aims to improve LPF with the two filters performance, capable of quick response and high steady precision. We also verified the strategy by simulations and practical experiment.
