串联混合型有源电力滤波器的优化分析-optimization analysis of series hybrid active power filter

华中科技大华中科技大学硕士学位论文IIIIAbstractIt has been a more and more important research project to suppress the power systems harmonics. And the applying of Active Power Filter(APF) will be the main solution. To provide the theoretical feasibility of harmonic suppression in high voltage level, Series Hybrid Active Power Filter based on Fundamental Magnetic Flux Compensation is presented. In order to ensure series hybrid active power filter (SHAPF) to operate normally in a better filtering effect, and to reduce the disturbance variable between the inverters, a single-phase SHAPF is presented in this paper. It separates the three-phase inverter which is connected to the secondary of the transformers into three sets of single-phase bridge inverters. So the currents are completely decoupled. And the next, detailed introduction of the principle of control strategy and the simulation research is given. Based on above, a prototype is constructed. The contrast tests show that it has a better filtering effect. Otherwise, as the series transformers are under harmonic voltage which causes distortion in the output of inverters, so the filtering effect will be affected somehow. It has been introduced in this paper to raise the DC voltage of the inverters to induce the proportion of the harmonic voltage. And test shows that it is feasible. In the last, a SVPWM control strategy is presented. This strategy has advantage of higher voltage utilization, less harmonic content and fewer switching loss. Therefore, the control strategy of SVPWM with seven segments is introduced. And a program is built in S-Function to realize it. This module is applied to the simulation of the SHAPF. As the simulation results show, it has a good filtering effect and stability.Keywords: Fundamental Magnetic Flux Compensation; Series Hybrid Active Power Filter; Three phase-three wire system; Single-phase bridge inverter; Space Vector Pulse Width Modulation PAGE IV PAGE IV目录摘要 (I)Abstract (II)1 引言1.1 谐波的基
