基于时间延迟理论的海上风电机组不定期检修策略
Irregular Maintenance Strategy for Offshore Wind Turbines Based on Time-delay Theory
摘要
Abstract
Due to the special operating environment for offshore wind turbines , it is often to replace parts as a whole when a failure occurs . Implementing condition‐based maintenance and selecting suitable replacement cycles is an effective strategy for reducing operational costs . But the condition monitoring and health diagnosis technology overseas are not reliable . Aiming at the problem , based on operation and maintenance logs , and the time interval between potential fault and functional fault , the time‐delay theory is introduced into the offshore wind turbine maintenance , and the law of development from potential failure to functional failure is modeled . Based on this , an irregular preventive maintenance strategy is proposed , and the parts replacement cycle is optimized . Case analysis shows that the proposed method can determine a set of optimal operational strategies , maintain the parts unit cost expectation at a low level . In the meantime , the results of sensitivity analysis can be used to make operation risk assessment for the optimized strategy .关键词
