Research on Control Algorithm Based on a New Hybrid Active Power Filter With Injection Circuit

非线性负载在电网中的大量使用导致了电能质量的恶化,因此需对谐波污染进行治理。基于一种新型35 kV注入式混合有源电力滤波器(IHAPF),在传统递推积分PI控制及滞环控制理论基础上改进了二者的缺点,提出了一种复合控制方法,可快速无差地跟踪指令信号。仿真及实验验证了所提方法的有效性及正确性。

The wide use of nonlinear load in power grid causes significant deteriorating of power quality.Thus it is imperative to handle the problem of harmonic pollution.A compound control scheme based on a new type of 35 kV hybrid active power filter with injection circuit（IHAPF） is proposed.This stratedy combines traditional recursive integral PI control and hysteresis control theories and improves them,thus realizes tracking the instruction signals quickly with no differences.Experimental results and engineering practices are provided to verify the analysis and design.
