Harmonic Assessment Based Adjusted Current Total Harmonic Distortion [PDF]

open access: yesThe Journal of Engineering, 2016
Power systems suffer from harmonic distortion and extra ohmic losses associated with them. Moreover, all harmonic frequencies are mostly assumed to have the same effect on the system losses. However, the frequency‐dependency of the resistances should be taken into account, so that the apparent power and the power factor have to ...
