| 摘 要： | 有源电力滤波器(APF)是电能质量治理中用于抑制电网谐波电流的主要装置。APF系统中,谐波电流检测的快速性、准确性决定了系统补偿谐波电流的性能。采用基于瞬时无功功率理论的谐波电流检测方法来解决谐波电流的检测问题。通过在EMTDC/PSCAD搭建模型进行仿真计算,验证了理论的正确性。通过制作样机进行测试实验,验证了基于瞬时无功功率理论的APF具有响应速度快、检测准确的优点。

| Abstract: | Active power filter （APF） is the main electronics device used to restraining harmonics and compensating reactive power. In the system of APF, the ability is up to the real timing and accuracy of detecting harmonics. In this thesis, it offers a harmonic current detection method is based on instantaneous reactive power referencing traditional arithmetic. In this thesis, EMTDC/PSCAD used to simulate detection method and a model machine used to empirical test. Experiments have shown that, the harmonic current detection method based on instantaneous reactive power have better response rates and accuracy. APF model machine can meet the harmonic compensation requirement. |
