HAPF一种控制策略的工作特性分析

An Operating Characteristics Analysis of One Kind of Control Strategy of Hybrid Active Power Filter

描述了混合型有源电力滤波器的拓扑结构,分析并仿真了一个HAPF系统采用负载谐波电流控制策略时,电网谐波电流分别在负载谐波电流、电源谐波电压、电网阻抗和电网频率这四种因素波动下的受影响程度(即灵敏度),实验表明系统具有良好的工作特性,说明了这个控制策略在该课题中具有可行性,同时为选择合适的控制器参数K提供了重要依据。

This paper describes the hybrid active power filter topology, analyzes and simulates the sensitivity separately when load harmonic current, power source harmonic voltage, electrical network impedance and mains frequency fluctuate. The hybrid active power filter system uses the load harmonic current control strategy. The experiment indicated that the system had the good operational performance, explained that this control strategy had the feasibility in this topic, as well as provided the important basis for the choice appropriate controller parameter.
