摘要：Power equipment usually goes through multiple states during the transition from normal state to the failure state. In order to consider equipment multistate property, an opportunistic maintenance optimization model based on multistate Markov process is proposed considering economic dependence within the transmission bay. This model describe equipment state transition process using the multistate Markov process. And then, opportunistic maintenance strategy between dependent power equipment in a transmission bay is studied. The transmission bay availability is derived considering opportunistic maintenance and scheduled maintenance. Finally, system operation cost is quantified. System operation cost is minimized to optimize equipment maintenance strategies. Numerical studies demonstrate validity of the proposed model.
