摘要
运用统一n+2状态马尔可夫模型,选择三峡机组投产至2006年(三峡工程二期结束及三期初期)这一典型阶段为主要研究内容,对三峡左岸电站在不同运行方式和负荷水平下进行供电连续性、充裕性的计算分析,并对各个元件可靠性参数进行敏感度分析,分析发现:改变发电机和断路器的故障率对整个电站的可靠性有显著影响,由此提出改善当前电站机组及系统可靠性的指导性建议。
Based on the generalized n＋2 state Markov model, this paper chooses the period between the beginning that the generators are brought into service and 2006 （the end of the second-phase of the Three Gorges Project） as the research content, and presents the continuity, adequacy and security calculation of the Three Gorges left bank power station. Also the reliability indices of different operating philosophies and load standards are compared and analyzed. The sensitivity indices of reliability of the Three Gorges power station with respect to equipment parameters and the reason why the reliability indices is low are analyzed, the results show that the influence on changing the failure rate of generators and breakers is obvious, and suggestions to improve the reliability are finally proposed.
