摘要
为提高系统电能质量,减少谐波污染,对一种新型双谐振注入式混合型有源电力滤波器进行了研究,分析了具有预补偿能力的分频检测算法和空间矢量双滞环电流控制方法在新型有源滤波器的应用。通过分频检测算法可以从实际工况选择待补偿的谐波次数,减少有源滤波器与电网其他补偿设备的耦合,提高系统稳定性,并减少了补偿容量。利用空间矢量双滞环电流控制提高了直流电压利用率,降低了开关频率。仿真和实验分析结果表明了该方法的可行性。
In order to enhance the system power quality and reduce the harmonic pollution,a new dual-resonance injection hybrid active power filter（DIHAPF） has been studied.The paper analyses the application of separate frequency detection algorithm with pre-compensation ability and dual-hysteresis current control method with voltage space vector in new style active power filter.The detection algorithm can selectively detect the pre-compensation harmonic number and lessen the coupling between DIHAPF and other compensation equipments,which is also able to improve the system stability and reduce the compensation capacity of DIHAPF.The current control maximums utilization of the dc bus voltage and reduces in the number of switches.Finally,simulation and experimental results show the feasibility of the proposed method.
