摘要
供电是石化企业自备热电厂的主要用途之一,对其可靠性要求非常高。介绍故障树分析法的基本原理,结合对重要负荷供电的四种运行方式,利用故障树分析法给出了每种运行方式下重要负荷供电中断的概率,并得出了四种运行方式下对重要负荷供电的可靠性排序,为选择合适的主接线运行方式提供了理论参考。
Power supply is one of the leading purposes for a SINOPEC enterprise owned thermal power plant（TPP） and the requirement of its reliability is very high. In the paper, the basic concept of fault tree analysis （FTA） is introduced. Based on the FTA method, probability of failure of power supply to important loads in each operating mode is gained in accordance with the characteristics of four operating modes. Reliability rank of supplying power to important loads in four operating modes, which provided the theoretical reference for selecting appropriate bus frame, is also presented.
