Abstract :
The purpose of this work is to analyze the problem related to the determination of the network harmonic impedances based on field measurements under steady-state conditions at the "point of common coupling" (PCC). No induced disturbances are utilized. For this purpose, a nonlinear method, a phasor method and correlation analysis are developed, investigated and compared. All of them use different operating points by changing the load. Numerical and practical difficulties are identified. Simulation and practical results are presented.
