Abstract

Associated with the sequence analysis of voltage measurement at one end of a transmission line, least square regression (LSR) is applied to determine the fault locations of this line under unbalanced faults in a non-radial wind power integrated electrical grid. Under this approach, the data-driven models illustrating fault characteristics are built in MATLAB/Simulink, so the fault locations can be accurately estimated for the facilitation of relevant protection schemes in real time. The effectiveness of LSR estimating fault locations is validated through a stochastic Monte Carlo simulation (MCS) with the involvement of noise.
