Journal: Transactions of China Electrotechnical Society

Keyword:  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: 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...
