In order to overcome the problems of multi-depart-ment coordination, multi-task combination, and repeated power outages in the traditional power outage management and control mode,an overall design scheme for a multi-dimensional power outage plan intelligent management and control system is proposed. Firstly, the concept of multi-dimensional blackout plan data pool is proposed, and the blackout plan management and control rule base is established. Based on this, intelligent optimization of multi-cycle blackout plans is automatically carried out by constructing a plan optimization algorithm model that meets the actual needs, including annual blackout plans intelligent optimization and rolling revision of the monthly power outage plan, and through the closed-loop management of the power outage plan to ensure the rigidity of the power outage plan. On this basis, the basic architecture and functional plan of the multi-dimensional power outage plan intelligent management and control system are proposed, and the design plan is implemented. The calculation example shows that the designed scheme is effective and feasible.
