Research On Shunt Active Power Filters With Selective Harmonic Compensation Control

Shunt Active Power Filter is harmonic suppression major research trends,this paper analyzed the selective compensation method,the selective application of the compensation method in Hybrid Shunt Active Power Filter in DC side voltage control strategy and key technologies to achieve selective harmonic compensation.This article focuses on the compensation method for the selective analysis,design and application of a selective harmonic compensation method based on current control and controls the sampling points within the grid constant problem for the fundamental cycle of the proposed method requires an optimized PLL,while the low-pass filter design and analysis;design applied a HAPF topology,the parallel combination of an inductor and a single active filter tuned passive filters to reduce the current APF on and selectivity Compensation Method used in this configuration,the flexibility to play compensation performance of the APF;for DC voltage directly affects the size APF power loss and compensation performance problems,the effect of voltage on the DC side APF loss and compensation performance is proposed based APF DC droop side voltage coefficient fuzzy adaptive control strategy,so that the DC voltage network side voltage changes with a corresponding change in the overall balance of the DC voltage APF compensation performance losses and the impact on the issues.Based on the analysis,design the same time,the proposed method is a MATLAB simulation,carried DSP programming,and on the low-power test system prototype hardware platform design experiments to verify the correctness and feasibility of the proposed method.As used herein,the research results of the mentor horizontal issues "Coal power harmonic suppression techniques in real-time online monitoring and research," as well as harmonic clean power has a certain practical value and important research significance.
