The invention discloses a power failure maintenance plan analysis and optimization system based on a kneading algorithm, and the system comprises an optimization system. The optimization system includes: a kneading algorithm model which optimizes the equipment maintenance time deviation period, enabling the workload arrangement to be reasonable, and has small the influence load of power failure maintenance; a plan generation module which classifies and arranges the power transmission and transformation equipment on the basis of intervals, and can complete arrangement of annual and monthly maintenance plans; a modification module which is used for manually maintaining the plan name and arranging time to manage the maintenance plan; a network topology module which is used for determining equipment capable of simultaneously participating in maintenance; a database which is used for storing data; a plan output module; and an intelligent power utilization cloud module. Corresponding manualadjustment can be performed on the scheduling result according to the actual situation, the workload of each department is reasonably arranged to improve the working efficiency, the kneaded maintenance plan is executed at the same time, the power failure frequency and the power failure time are reduced, and the intelligent degree and the management capability of the maintenance plan are improved.
