Abstract

A revised generator random outage model is investigated in this paper which is used in risk-based monthly generator maintenance scheduling. First, the reason why the time-varying unit outage model should be used in monthly maintenance scheduling is presented. Second, the delayed renewal process was proposed to formulate the outage model for unscheduled units. This model can accommodate the impact of maintenance on failure rate. Third, a novel outage model for scheduled units was proposed to accommodate the scenario that force outage happened before maintenance for scheduled unit. Lastly, some numerical tests on risk-based monthly generator maintenance scheduling were given, which demonstrate the proposed outage model reasonable.
