| 摘 要： | 基于瞬时功率理论的谐波检测方法由于锁相环和低通滤波器的存在,给检测环节带来了一定的延时,使得谐波电流的检测存在一定的误差。本文通过增加预测补偿角来消除该环节带来的延迟时间,从而能够更加准确、有效地得到谐波补偿指令信号。最后利用MATLAB搭建了仿真模型,仿真结果表明了该方法的有效性。

| Abstract: | Because of delay of detecting links of the phase-locked loop and the lower-pass filter,the method of harmonic detection based on instantaneous power theory have some aberration.Through adding forecasting compensation angle for delay time,the method can effectively get more accurate harmonic compensation instruction signals.Finally,this paper had built simulation model by using MATLAB.The simulation results show the effectiveness of the method. |
