Development of a Parallel Hybrid Power Filter with Respective Harmonic Compensation Method

分次补偿方式的并联型混合电力滤波器研制

Closed-loop system transfer function of inner current loop has the right half plane zero and close from the imaginary axis, so that the control system Q value is larger and the setting time is longer. It lags the system harmonic compensation time.

系统电流内环闭环传递函数中存在右半平面零点且距虚轴较近，这样造成控制系统Q值较大、调节时间加长、系统谐波补偿滞后。

This algorithm can overcome the infection of the digital controller's delay time to harmonic compensation and realize the real time compensation.

该算法能够克服数字式控制器所产生的延迟时间对于谐波补偿的影响，可实现谐波的实时补偿。
