中文摘要:
      针对不平衡电网下并联混合有源电力滤波器(Active power filter,APF)和无功补偿装置体积过大和系统损耗的问题,提出一种在不平衡电网下的静止无功发生器(Static var generator,SVG)和APF并直流母线联合运行系统。其中,SVG主要用来快速补偿无功和电网不平衡,APF滤出电网和SVG的特定次谐波。该联合系统通过并直流母线减小了电容的体积,使系统总体积减小;降低SVG的开关频率使系统损耗减少。对系统环流抑制策略进行了分析,并确定了在从模块上加入环流进行抑制环节,解决了并联系统中出现的环流问题。最后通过MATLAB/SIMULINK仿真验证了该联合系统的可行性。
英文摘要:
      Aiming at the problem of excessive volume and system loss of parallel hybrid active power filter (APF) and reactive power compensation device under unbalanced grid, A static var generator (SVG) and an APF and DC bus joint operation system under an unbalanced power grid are proposed. Among them, SVG is mainly used to quickly compensate reactive power and power grid imbalance, and APF filter out the specific harmonics of power grid and SVG. The combined system reduces the volume of the capacitor through the and DC bus and reduces the total volume of the system; Reducing the switching frequency of the SVG reduces the system loss. The circulation suppression strategy of the system is analyzed, and the circulation of the module is added to the suppression link, and the circulation problem in the parallel system is solved. Finally, the feasibility of the joint system is verified by MATLAB/SIMULINK simulation.
