摘要
Abstract
By analyzing the single-phase series active power filter (SAPF) of the structure, a single-phase SAPF system harmonic detection method is proposed. Meanwhile, based on the principle of single-phase SVPWM technique, the control accuracy of system waveform is improved by applying the Optimal Switching Pattern SVPWM technique to a single-phase SAPF system. Finally, the simulation model of a single-phase SAPF system, which takes advantage of the harmonic detection and system waveform control techniques mentioned above, is established using Matlab software. And this model is used to simulate the dynamic compensation of the failure state of dynamic voltage, such as system voltage drop and flicker. The simulation results indicate that the SAPF filtering system presented in this paper has good filtering performance. Furthermore, this new technique can protect load from the influence of system voltage failure, and has a good prospect of engineering application in the future.关键词
