Random harmonic current detection based on ipiq principle in three phase four wire system and its realization on the platform of LabVIEW
Abstract:The key problem in APF is to detect the harmonic current accurately in real-time mode. This paper takes ipiq method used in the harmonic detection in the system of three-phase four-wire on the platform of labVIEW. can detect positive, negative and zero phase sequence current component of random harmonic current respectively. Finally the detected positive, negative and zero phase sequence can be summed up to obtain the random harmonic current. The random harmonic detection system is designed and implemented with simple structure, high possessing and precision, which can be well used in practice.
