| 摘 要： | 针对电网用户端谐波源的某次或若干次超标的谐波电流进行补偿具有重要的实用意义。该文提出一种改进的离散傅立叶变换(HDFT)和离散傅立叶反变换(IHDFT)算法，在基于数字信号处理器(TMS320C32)的并联型有源电力滤波器中，对电网用户端的谐波电流信号进行离散化分频，并依据分频结果获取补偿指定次或指定若干次谐波的指令信号。最后，本文还对该算法建立仿真模型，判断谐波的补偿效果，并通过实验予以验证。

| Abstract: | The compensation of the given order or given several orders harmonics of the users in the network is very important for application.An algorithm of advanced HDFT and IHDFT is proposed in this paper.In a shunt-active filter depending on digital signal processor (TMS320C32),the fractional frequency of the harmonics current signal of network users is discretized with the result that the current compensation command signal of the given order or the given several orders of harmonics is obtained.thereby,the simulating model is built up in this paper,the compensating result is judged and proved by experiment. |
