摘要:
本文通过对风力发电机电控系统中的机舱柜、机塔柜和轮毂柜故障进行分类，故障按照一般故障与严重故障进行分级处理，对风力发电机组系统可靠性进行评估，通过对电控系统可靠性运用故障树理论进行分析，得出最高故障率可达20%，最低为0.2%的结论。实际中应及时采取有效针对性强的措施对风机进行日常定检维护与故障处理，可以很大程度上提高风机的正常运行时间。利用故障树分析方法对风力发电机组运行维护给予指导，提高可靠性。
In this paper, it classifies all faults into general and serious failure in nacelle and hob control system. First, it evaluates the reliability of a system of wind turbine. Then, it assesses the reliability of electric control system by fault tree analysis, the conclusion is the highest failure rate of up to 20%, the lowest to 0.2%. In fact, in order to avoid accident and increase uptime, we should take Long-term and effective measures to periodical daily examination and maintenance. It gives guidance to operation and maintenance of wind turbines by fault tree analysis in order to improve reliability.
