  • System, method and computer program product for fault detection and location in power grid
    Patent number: 11150639
    Abstract: A method, system, and computer program product, include recording high-frequency wave data of local arid adjacent fault curves of a power grid to compare the high-frequency wave data with historical fault data to detect an actual fault region in the power grid, the power grid having a plurality of sensors distributed in the power grid, each sensor being upstream of one adjacent sensor and downstream of an other adjacent sensor.
    Type: Grant
    Filed: February 26, 2019
    Date of Patent: October 19, 2021
    Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
    Inventors: Xin Jie Lv, Lingyun Wang, Wei Da Xu, Chao Zhang, Ke Xu Zou

  • System, method and computer program product for fault detection and location in power grid
    Patent number: 10324459
    Abstract: A method, system, and computer program product, include obtaining a dataset related to a power grid collected by a plurality of sensors distributed in the power grid, identifying a region as a candidate fault region based on first data in the dataset, the first data being collected by a first sensor from among the plurality of sensors that is located in the region, and verifying the candidate fault region based on second data in the dataset, the second data being collected by a second sensor from among the plurality of sensors that is adjacent to the first sensor.
