摘要

This paper proposes a simple, accurate and non-iterative fault location scheme for series and shunt compensated transmission lines. The proposed algorithm utilizes unsynchronized measurements from the two ends of a transmission line and the monitoring system if a fixed series compensation (FSC) device is installed. Data synchronization is carried out using post-fault data samples to increase the accuracy. The proposed algorithm is independent of the reference bus selection and is extensively tested for all major fault types and fault resistance variations. The results prove that the proposed algorithm yields accurate estimate of fault location.
