# 基于瞬时无功功率理论的改进谐波检测APF设计The Design of a Improved Harmonic Detection Method APF Based on Instantaneous Reactive Power Theory

Abstract: Due to the application of a large number of power electronic devices in the grid, the harmonics problem is serious. The first to solve the harmonics problem is detection of harmonic components in power grid. The basic principle of the instantaneous power system of three-phase-three-wire system in reactive power theory is extended to three-phase-four-wire system by examining the practicability for harmonic detection in low voltage distribution network system with zero sequence current. In the process, for solving a tradeoff between maladjustment and the speed of dynamic response in the conventional detection method, the low-pass filter is substituted by current average method. By using the platform of Matlab to prove its applicability and highly active ability, it aims to prove that the improved method can resolve problems between accuracy and response speed and be more efficient detection of current harmonics. Thus we can calculate the referential current to complete the compensation of grid current.
