摘要
从数字化变电站自动化系统功能标准化和自由分布等特点出发,引入GO法,提出了基于GO法的数字化变电站自动化系统可靠性分析方法,即基于IEC61850标准,将系统功能分解为逻辑节点连接图。并以此建立系统功能GO图,计算功能的可靠度以评估系统的可靠性。以间隔联锁功能为例,对功能可靠性建模和定量计算过程等进行了详细的介绍,以T1型变电站为例,对方法的可行性进行了进一步论证。
From the characteristics of standardization and free distribution of function of digital substation automation system, GO method was introduced into the field of digital substation automation system reliability analysis, which meant decomposing the system function into connection diagram of logical nodes based on IEC61850 and building the GO chart of systems function with GO method, then calculating the reliability of function and taking it as the reliability index of system. The interval interlock function was taken as the example to introduce the modeling process and quantitative calculation of method in great detail. The feasibility of method with example of T1 substation was further confirmed.
