Fast and accurate location of faults on long transmission lines is essential for modern grid. In this paper, a double-ended traveling wave fault location system based on FPGA and DSP is designed as a plugin to be integrated into the protection relays. Traveling wave signal is captured from the existing sampling circuit of the protection relays and fault location is achieved using wavelet transformation. Simulation data generated by RTDS simulator is used to verify the performance of the system. The results show that the system can locate the fault accurately.
