Control Method And Simulation Research Of Active Power Filter

This paper discussed the eliminated technique of the load humorous and power factor. A fund method is install a harmonic compensate equipment. At first this paper introduced the humorous problem in the electricity, and putting forward the nation of studying a harmonic meanings and the present condition. In the aspect of eliminated technique, this paper emphases to investigate the series active power filter and shunt series active power filter, dispart the series active power filter control into two-layer structure, the inner layer face the main loop to track the reference current or voltage. The outer layer computes the reference and keeps the capacitance voltage invariableness. Aim at the complexion of national research focus on the outer layer control, the paper introduce the Space Vector Pulse Width Modulate and deadbeat control into the active power filter's inner layer control, and analyses its' principium and simulate its' controlled method. The result indicate the Space Vector Pulse Width Modulate and deadbeat control not only be prone to realize digital computer control, but also can excel the traditional method in the aspect of performance.In the base of analyses and simulation, discussed the shortcoming of the series active power filter and shunt series active power filter, and give the structure and control method of a integration of series and shunt active power filter, the simulation prove it can make up the shortcoming of the series active power filter and shunt series active power filter.
