Harmonic distortion monitoring for nonlinear loads using neural-network-method

► A neural-network-method applied to measurement systems is presented. ► Analytical and experimental analysis of a nonlinear power system is presented. ► Harmonics and total harmonic distortion measurement of load current are carried out. ► The method can be applied to online metering systems for smart grid and power quality purposes. ► The method requires less computational efforts than traditional FFT analysis.
