Line Impedance Estimation

IEEE Transactions on Instrumentation and Measurement, 2021
Line impedance estimation provides crucial information for power-line communication (PLC), power quality estimation, and grid-connected power electronics applications. Online techniques are particularly useful as the line impedance is time-dependent. This work uses a phase-controlled switch to generate a turn-on transient, which provides information ...

Estimation of PP‐ wave ray impedance from elastic impedance

SEG Technical Program Expanded Abstracts 2011, 2011
Theoretical evaluation of elastic impedance (EI) and ray impedance (RI) reveals that RI has a more reliable dimension and is less sensitive to errors than EI. In this paper, a new measurement (R I) is proposed to estimate ray impedance from the elastic impedance derived by existing techniques.

Robust Magnetotelluric Impedance Estimation

AIP Conference Proceedings, 2010
Robust magnetotelluric (MT) response function estimators are now in standard use by the induction community. Properly devised and applied, these have ability to reduce the influence of unusual data (outliers). The estimators always yield impedance estimates which are better than the conventional least square (LS) estimation because the ‘real’ MT data ...

Estimating Cole-Impedance Parameters from Limited Frequency-Band Impedance Measurements

2021 IEEE 12th Latin America Symposium on Circuits and System (LASCAS), 2021
Particle-swarm optimization is applied to estimate the parameters of 4 different Cole-impedance models using impedance measurements limited to frequencies within 1 kHz to 1 MHz, representative of typical ranges for bioimpedance applications. The accuracy of extracted parameters are compared for cases with $N$ = 201, 25, and 5 datapoints collected ...
