Study of control strategy for three-phase four-wire APF based on non-harmonic detection
摘要
Abstract
In view of the problem of three-phase four-wire distribution system with serious harmonics pollution and lar-ger unbalanced neutral harmonic current , this paper presents a three-phase four-wire active power filter ( APF) based on the control strategy of non-harmonic detection .It establishes the mathematical model of three-phase four-wire APF with mid-point capacitor , and gives the design method of main parameters of inductance and capacitance .Control strategy of harmonic detection and non-harmonic detection are analyzed , and non-harmonic detection method is select-ed as the main control strategy finally .Controller of proportional resonant ( PR) is designed to eliminate negative har-monic and the zero sequence current .Simulation of the three-phase four-wire APF is built in Matlab/Simulink envi-ronment to test the result for harmonic compensation and suppression of neutral line current , and it shows the remarka-ble effect of comprehensive improvement .Finally, an experimental platform taking TI TMS320F28377 as the main controller is built to verify the feasibility of the control strategy .关键词
