Hybrid maintenance strategy analysis based on critical equipment reliability and outage events

Based on the equipment reliability theory, this paper establishes a hybrid maintenance model based on the reliability of key equipment and power failure events, considering the impact of power failure events on system operation based on the reliability theory and the actual operation of the power grid. The effectiveness of the proposed model and method is verified by simulation analysis, which can effectively reduce the maintenance cost and improve the reliability of power system operation and power supply, which is of great significance for realizing the safe, reliable and economic operation of power grid.
