摘　　要：利用跟踪微分器,对谐波补偿信号进行相位超前校正,进而补偿谐波提取算法以及系统引起的谐波信号相位滞后,实现有源滤波器的零相位差滤波,最终提高其谐波滤除性能。通过比较普通微分器与跟踪微分器,选择合适的参数使跟踪微分器满足有源滤波器谐波信号超前校正的需求。在原理分析的基础上,利用原始数据对有源滤波器谐波信号提取以及相位超前校正进行了仿真研究。最后设计并实现了基于跟踪微分器的独立电网有源滤波器控制系统,和原有的系统进行比较,验证了跟踪微分器在提高有源滤波器谐波滤除性能方面的作用。The tracking differentiator is adopted to pre-adjust the phase of harmonic compensation signal for removing the phase delay caused by system and harmonic detection algorithm and improving the performance of active filter.The normal differentiator and tracking differentiator designed for active filter used in islanded power system are compared and proper parameters of tracking differentiator are chosen.Simulative study with original data is carried out based on the theoretical analysis for harmonic detection and phase pre-adjustment.The active filter control system based on tracking differentiator is designed and developed for islanded power system and its comparison with the original system shows the effect of tracking differentiator on the performance improvement of active filter.
