针对电网电压扰动的Vienna整流器复合控制方法
Research on new hybrid control method for Vienna rectifier under disturbed power grid voltage
摘要
Abstract
In this paper, an improved current tracking method is established which is used in the three-phase-four-wire Vienna rectifier.It aims at solving the back-ground harmonic and collapse voltage problems brought by the power grid.Meanwhile, considering the perish current tracking performance and precision in the conventional PI control strategy,a novel control strategy combined PI control strategy with the repetitive control strategy is put forward.In this paper,it makes qualitative analysis on the novel current tracking method,and it also does enough analysis and com-parison about repetitive controller design.The superiority of the novel control method can be shown through contrast of two methods on harmonic suppression characteristics, and finally, an experimental prototype of 3 kW is built.The simulation and experimental results have proved the feasibility and effectiveness of the novel strategy.It has high tracking precision and it can also improve the wave quality of the input current effectively.When the distortion rate of grid current is reduced,the fluctuation of the output voltage is also slighter.So it can maintain perfect output charac-teristics.关键词
