Research on the Optimization Method of Power Network Maintenance Plan Based on Equipment Importance

The preparation of maintenance plan of power grid is directly related to the safe and reliable operation of all kinds of equipment in the power grid and the reliable power supply of power users, which is an important work content of power grid dispatching management department. Different importance of different equipment should be considered in making maintenance plan of regional power grid. Aiming at different types of equipment, this study optimizes the equipment maintenance plan and arranges different maintenance time, thus reducing the maintenance cost. This optimization method has strong practical significance in the process of making maintenance plan, and can be widely used in practical projects.
