摘要(Abstract)：
针对传统谐波电流检测方法受低通滤波器影响动态响应慢的问题,提出采用基于周期信号滤波器和低通滤波器的组合型滤波器,在不影响电流检测精度的前提下,大幅度提升了动态性能。通过MATLAB/Simulink仿真对所提方法进行验证,动态响应时间仅为传统方法的1/3,充分验证了所提方法的正确性和有效性。
Aiming at the slow dynamic response of traditional harmonic current detection method affected by the low-pass filter, the paper proposes a combined filter based on periodic signal filter and low-pass filter,which greatly improves the dynamic performance without affecting the accuracy of current detection. The proposed method is verified by MATLAB/Simulink simulation. The dynamic response speed is only one-third of the traditional method, which fully verifies the correctness and effectiveness of the proposed method.
