摘要
简要介绍瞬时无功功率理论,分析讨论了基于该理论的pq检测算法及其改进而形成的ip iq法,明确提出一种新的谐波检测方法。该算法不但可以检测出电流谐波,还可以检测出电压谐波。该检测方法计算更加简单,可进一步提高检测精度,且具体实现时可节省部分硬件电路。仿真与实验结果验证了该文所提出算法的有效性。
The instantaneous reactive power method has been introduced briefly in the thesis. After analysing the pq detect algorithm and ip-iq algorithm, a novel method for detecting harmonics was proposed, which is able to detect current harmonic and voltage harmonic. In additional, this method can improve the detect accuracy, and also reduce the hardware circuits efficiently in the implemention. Finally, the detailed simulation and experimental results verified the validity of this method.
