Abstract


With the widespread use of power electronic devices, grid harmonic pollution become more and more serious, but high power quality has become increasingly demanding for users.Therefore, harmonic wave management has become a major research field and a urgent problem. Active power filter (APF) with its superior compensation performance is the most effective and promising in the comprehensive management of "grid pollution", in which shunt active power filter (APF) is the most widely used.This Paper first introduces the basic principle of active power filter, current research situation and development trends, and describes the classification of active power filters, the emphasis is to analyze the main circuit topology and its mathematical model established of the three-wire three-wire shunt APF.Then,this paper has a detailed analysis of p-q computational detection method based on the instantaneous reactive power theory and improved ip-iq computational detection of harmonic detection method, and studies the two methods comparatively,and low-pass filter design and system delay compensation has been studied.Through the simulation study for the Improved computing detection method, it verifies that the method is feasible and correct.to detect the harmonic current in different situations.For their own advantages and disadvantages of self-adaptive fuzzy recursive integral PI control and hysteretic current control in harmonic compensation,this paper raises a combined control method that includes a fuzzy self-adaptive recursive integral PI control and hysteresis current control, in which hysteretic current control is used to improve the dynamic response speed of system and the self-adaptive fuzzy recursive PI control is used to ensure that the static accuracy. In order to ensure the stability of DC voltage in active power filter, we use the PI controller to control the DC voltage, and through the simulation of matlab,it verifies that the combined control algorithm has fast response time with no steady-state error characteristics,realizing no-error control. Finally, this paper designs the active power filter control systembased on the TMS320F2812 digital signal processor,and its hardware and software design are discussed in detail.
