Intelligent regulation and control system and method for power failure and recovery of power grid

The invention discloses an intelligent regulation and control system and method for power failure and recovery of a power grid. The intelligent regulation and control system comprises a power grid monitoring module, the lower end of the power grid monitoring module is connected with a power grid fault recognition module, and the lower end of the power grid fault recognition module is connected with a power supply path screening and evaluating module. The lower end of the power supply path screening and evaluating module is connected with the graphical display module, the lower end of the graphical display module is connected with the control module, and the power grid monitoring module automatically identifies power grid faults through power grid steady state data, monitoring alarm information and protection action information in combination with a Petri network. The intelligent control system is effectively improved, the power grid fault can be accurately judged, and the range influenced by the fault can be
