摘　　要：配电系统自动化的可靠性对于整个电力系统的可靠性至关重要。提出了一种在配电系统元件发生故障情况下基于IEC61580标准的配电系统自动化的可靠性评估方法。首先简要介绍了IEC61850规约、配电系统自动化的构架以及主要功能。然后提出利用故障树分析方法来量化该系统的可靠性指标,利用概率模型来估计系统元件故障率、修复时间等可用性指标,从而计算IEC61850系统的可靠性。并分析了在线路故障和母线故障的情况下,基于IEC61850配电自动化系统中故障定位情况以及与配电系统可靠性的关系。最后对所提方法在RBTS上进行了仿真分析,验证了所提方法的正确性。The availability of distribution automation is crucial to the entire power system.In this paper,a reliability assessment method for the distribution automation based on IEC 61850 is proposed.First,the fundamentals of IEC61850 protocol and the structure of the distribution automation as well as its main function are illustrated.Then the fault tree analysis method is used to assess the reliability of the system.The probability model is used to calculate the fault rate and repair time,etc.in order to obtain the entire reliability.Next,taken the line fault and bus fault as examples,the fault location and reliability calculation are analyzed.Finally,the proposed method is tested on the RBTS to demonstrate the effectiveness of the method.
