The usage of synchrophasor for optimised fault localization method

Popis výsledku v původním jazyce

Common methods for fault localization require for proper function a lot of specialized instruments. These special instruments should be permanently installed or moved to required distribution area. New fault location method needs only a few synchronouslymeasured voltage and current phasors in the fault time for its proper function. The OHL parameters are used for more accurate calculation. The fault is located very quickly using relatively small amount of explained input data and a very special methods. This method can be performed on-line without the line to be switched off. The solving algorithm is based on matrix multiplication with discrete optimization. This is due to the fact that each line segment can be described as the matrix with OHL parameters. During the calculation the immediate fault rate is traced. The evaluation time strongly depends on the computer calculation capabilities and required accuracy.
