A Harmonic Current Algorithm of Single-phase Circuit Based on Compensated Currents
In order to realize accuracy and real-time for harmonic current detection in the active power filters,a harmonic current algorithm of single-phase circuit based on compensated currents is proposed in this paper for the harmonic harm and the harmonic pollution issue in power systems.The algorithm transforms the harmonic current detection problem into the problem of fundamental active current amplitude by the construction function,which is based on the minimum compensated currents.The experiments show that the new algorithm in this paper has the advantage of low computational and good real-time.It is also easy for the engineering implementation.And this kind of APF based on the minimum compensated currents compensates harmonic current effectively of the good dynamic performance.The simulation results illustrate the validity and effectiveness of the presented algorithm
