摘    要:在分析注入式混合型有源电力滤波器基本工作原理的基础上,建立其数学模型,并以此为基础分析了逆变器基波环流的产生及危害.为消除逆变器输出中的基波成分,确保系统的安全稳定运行,提出了一种注入式HAPF的注入电流和逆变器输出电流双闭环控制策略.注入电流控制外环实现注入电流完全跟踪负载谐波电流,保证系统的精度;逆变器输出电流控制内环对输出电流进行限制,抑制系统的谐振,加入阻尼,保证逆变器的安全可靠运行.仿真及实验结果验证了本文所述控制策略在谐波控制精度及系统安全可靠性方面的优势.

关 键 词:谐波抑制  无功补偿  基波环流  注入式混合型有源电力滤波器

Abstract:Based on the analysis of hybrid active power filter(HAPF) with injection circuit, the control model of the proposed HAPF is established. And then the origin and harm of fundamental current circumfluence are discussed. To eliminate fundamental component of the inverter output current, the paper proposes a novel control strategy composed of injection circuit outer control loop and output current of inverter inner control loop. The outer control loop based on the detection of injection current is used to carry out high precision, while the inner control loop based on the detection of APF output current is used to ensure the system security. Simulation and experimental results show the proposed control methods can meet the requirement of HAPF controller and have high precision, good security and stability.
Keywords:Harmonic suppression  reactive power compensation  fundamental current circumfluence  hybrid active power filter with injection circuit
