摘要
在深入分析有源电力滤波器(APF)和静止无功发生器(SVG)工作原理的基础上,提出一种基于I_p-I_q检测技术的自适应谐波与无功治理方法。检测三相负载电流并计算相应的补偿电流,对比装置的最大输出补偿电流与待补偿电流的大小关系,给出相应的补偿策略,裁决优先补偿谐波或优先补偿无功及谐波与无功共补。电网存在扰动致使装置输出最大补偿电流小于待补偿电流时,可保护功率开关器件。通过仿真和实验,验证了自适应谐波与无功治理方法的有效性。
On the basis of analyzing the working principle of active power filter (APF)and static var generator (SVG),an adaptive harmonic and reactive power control method based on Ip-Iq detection technology is proposed.Three phase load current is detected and the corresponding compensation current is calculated.The relationship between the maximum output compensation current of the device and the current to be compensated is compared.The corresponding compensation strategy is given,and the priority compensation harmonic or priority compensation reactive power and harmonic and reactive power compensation is awarded.At the same time,there is disturbance in the power grid,which can protect the power switch device when the maximum compensation current of the device is less than the current to be compensated.The effectiveness of the proposed control method is verified by simulation and experiment.
