A power grid fault diagnosis and transmission line parameter identification system

Abstract

The invention discloses a power grid fault diagnosis and transmission line parameter identification system, comprising a fault characteristic analysis module, a fault intelligent diagnosis module, a power grid fault deduction module, a line parameter identification module, a FIS application of a protection information management master station, and a visualized man-machine interface; The input terminals of the fault characteristic analysis module, fault intelligent diagnosis module, power grid fault deduction module and line parameter identification module are all connected to the FIS application of the protection information management master station, and the output terminals are all connected to the visual human-machine interface. The power grid fault diagnosis and transmission line parameter identification system provided by the embodiment of the present invention provides auxiliary tools and convenient means for professional grid management and operation personnel to quickly locate grid fault problems and check transmission line parameters.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of a power system protection information management master station, and in particular to a power grid fault diagnosis and transmission line parameter identification system. Background technique [0002] At present, the power grid will generate a large amount of fault recording data every year, but the application of fault recording data is limited to relay protection for fault diagnosis and troubleshooting. The application range of fault recording data is small and the application depth is shallow, which cannot adapt to the operation of smart grid. requirements. There are mainly the following problems: [0003] (1) When complex faults or abnormal protection actions occur in the power grid, professional management and operation personnel cannot quickly and accurately judge the nature of the fault based on numerous discrete fault information such as protection action events, fault re...
