Analysis of DC-side Voltage Control of Shunt Active Power Filter
摘要
Abstract
When a shunt active power filter(APF)is connected to the power grid,some engineering problems exist in the DC-side voltage,such as large starting static difference and large overshoot.Based on the traditional PI control,a P-fuzzy-PI multi-mode control algorithm for input pressure difference square values is adopted on the DC-side voltage, and the switching value of the threshold is determined using a fuzzy-rule multi-mode switching controller.Finally,feasi?bility analysis is performed in simulation software Matlab/Simulink,and it is found that the static difference rate and overshot decrease when the DC-side capacitor voltage increase from zero up to the expected stable value;meanwhile, the pressure difference square reduces the no-load current and accelerates the response speed.Simulation results show that the proposed control algorithm is superior to the traditional PI control,and it has a good prospect for engineering ap?plications.关键词
