摘要：
Affected by various factors, a maintenance process of circuit breaker has certain randomness, which cannot be accurately described. The relationship between the single maintenance randomness and the remained faultless time is analyzed and an MTTF(Mean Time To Failure) model considering the influence of maintenance process randomness is established to reflect the reliability of circuit breaker after maintenance. The calculated MTTF of circuit breaker after maintenance is taken as the optimization period for next maintenance and with the minimal sum of preventive maintenance cost, fault maintenance cost and outage cost as its objective function, a maintenance strategy considering both reliability and economy is developed. The system risk induced by the quitting out of circuit breaker for maintenance and the potential system risk by its continuous operating are analyzed and a concept of circuit breaker maintenance urgency is proposed, which is used to determine the maintenance sequence for several circuit breakers to be maintained in same period. A case analysis for IEEE-RBTS verifies the feasibility and effectiveness of the proposed method. © 2016, Electric Power Automation Equipment Press. All right reserved.
