Automatic fault detection method for smart grid energy routing nodes

Under the implementation of current hardware of the grid, faults appear frequently in routing nodes and require effective detection. This paper achieves accurate locating and isolation through the efficient detection of faults. Experiments show that it could not only improves the low detection rate and poor fault location accuracy of the current method, but also isolates faults and has strong reliability. The formulation of future development directions is as follows:(1) In order to further improve the quality of fault detection, the interference of grid can be removed in advance;(2) The repair content of the fault should be added to improve the fault detection process. The grid fault detection method based on the immune mechanism and the grid fault detection method based on the limited PMU have a low accuracy of fault location, especially the grid fault detection method based on the limited PMU, of which the fault location accuracy is far lower than the requirements of fault detection technology.
