Condition based Maintenance Optimization for the Hydro Generating Unit with Dynamic Economic Dependence

Xinbo Qian, Yonggang Wu
2014 International Journal of Control and Automation  
This paper considers a condition-based maintenance (i.e. CBM) model for the hydro generating unit in the deregulated power system.  ...  The reason for the cost-saving of the proposed DED&PHM based CBM policy is that, the preventive maintenance is inclined to be performed during the periods of low downtime costs.  ...  In this paper, we propose a Dynamic-Economic-Dependence and Proportional hazard model based CBM (DED&PHM based CBM) policy for the generating unit as a multi-component system.  ...
