| 摘要: |
| 集中式站域保护作为一种新型保护系统，其构建模式与传统保护系统存在较大差异。根据集中式站域保护的结构和运行特点，综合考虑各组件的失效和修复过程以及站域保护系统的容错功能，建立集中式站域保护可靠性分析模型和间隔等效可靠性模型。利用故障树和蒙特卡罗仿真相结合的方法，计算集中式站域保护系统可靠性指标，并与传统保护系统的可靠性指标进行了对比分析。 |

| Abstract: |
| The centralized substation protection is a new type of protection system and its construction mode is quite different from that of traditional protection system. According to its structural and operational characteristics，a reliability evaluation model of centralized substation protection and an equivalent bay reliability model are built，which consider the failure／recovery process of different components and the fault-tolerant function of substation protection system. The fault tree method and Monte Carlo simulation are applied to calculate the reliability indexes of centralized substation protection system and they are then compared with those of traditional protection system. |
