Embodiment Construction

[0029] The present invention will be further described below in conjunction with embodiment.

[0030] An automatic identification method of power grid fault level based on multi-source data fusion, such as figure 1 , 2 As shown, it includes power dispatching system, information interaction bus system and power grid fault level automatic identification function module. The power dispatching system serves as a supporting platform for the automatic identification of fault levels in the power grid; the information interaction bus system is responsible for integrating data between transmission systems, sharing the data with the power dispatching system, and providing basic data for the identification of fault levels in the power grid; including multi-source data The integrated power grid fault level automatic identification function module realizes the power grid fault level automatic identification function.

[0031] The present invention provides an automatic identification met...
