摘要
The invention relates to fault section and location identification in a multi-terminal mixed line, which connects three or more terminals with at least one overhead line and at least one cable. Here, the mixed line has three or more line sections connected at one or more junctions. The method comprises obtaining arrival times of travelling waves detected from measurements at the three or more terminals. Further, at least two values are estimated for the fault location, based on the arrival times, length of two or more line sections, and wave propagation velocity. One of the line sections is determined as having the fault based on a comparison of the at least two values with length of corresponding line sections. The corresponding value is determined as the actual fault location. According to the fault section identification, a trip signal is generated for controlling a switching device connected with the mixed line.
