Abstract

Due to the defects of existing fault location methods for multi-terminal transmission lines, such as the fault branches judgement algorithms are too complex to implement, a new fault location method based on phase comparison is presented. In this method, transmission lines are classified into branch and artery section, and the fault intervals and fault phases are determined by comparing the phase between two measurements which installed in the lines using Kaiser self-convolution windows FFT. Based on double-terminal traveling wave theory, the final fault distance can be achieved. Extensive PSCAD/EMTDC simulations are performed to verify the high precision of this method.
