Network parameters error may seriously affect the accuracy of fault location results, even making them unacceptable in extreme cases. This paper proposes a new method which incorporates these errors in wide area fault location problem using phasor measurement units(PMU) to estimate inaccurate network parameters employing robust state estimation. Our proposed method is composed of two stages. The first stage or the primary stage provides an initial point for the second stage which is the main contribution of this paper. Additionally, the set of measurements contaminated with bad data could be obtained from the first stage and its intersection with leverage measurements are then eliminated from the measurement set before feeding it into the second stage. Finally, fault point and faulted line parameters are estimated by the main(second) stage of the method. The proposed method has been applied to two test systems, namely Institute of Electrical and Electronics Engineers (IEEE) 14-Bus and IEEE 57-Bus systems to evaluate its accuracy. Simulation results indicate high accuracy and consistency of the proposed method.
