故障树分析（FTA）作为全球公认的系统风险分析和可靠性评估的有力工具，普遍用于系统的设计，开发和运营。主要运用FTA 对电力系统的可靠性及该技术的应用进行讨论。采用的方法是生成电力系统各负荷点的故障树，使故障树各个中断的能量传递从相关发电机到特定的负载点。运用最小割集的布尔方程组方法，定量分析故障树方法对电力传送的可靠性评估。电力系统可靠性评估和影响电力系统可靠性的主要因素是确定的，可以通过定性和定量分析得到。

Fault tree analysis (FTA),a globally recognized useful tool for evaluating system risk analysis and reliability evaluation,is widely used for system design,development and operation.This paper uses FTA to discuss the reliability of the electrical power system as well as application of the technology.Fault trees are generated for each load point of the electrical power system so that disrupted energy of the fault tree may be transmitted from the related generator to the specific load point.The Boolean equation of the minimum cutest is applied to make a quantitative analysis on the reliability evaluation of the power transmission by the fault tree method. Reliability evaluation of the power system and main factors affecting the reliability of the power system are determined and can be obtained through the qualitative and quantitative analysis.
