摘要/Abstract

摘要：

目前对于变电站自动化系统的可靠性研究鲜有涉及人为因素的定量影响，而许多电网事故是由人为失误引起的，因此提出了一种计及人因可靠性的变电站自动化系统失效风险评估方法。首先根据工作人员所处场景采用层次分析法-成功似然指数法评估人为失效概率以此修正设备故障概率，其次基于IEC-61850的功能分解对自动化系统各种功能的失效风险进行评估，最终融合为系统失效风险，以此描述当前系统可靠性，为调度部门决策提供指导。算例结果表明，人为因素对于系统失效风险有着较大的影响，计及人因可靠性可更为客观地描述系统风险，为调度操作人员提供风险预警。

Abstract:

Currently, there are few research on the influence of human reliability upon the reliability of integrated substation automation system (ISAS). This paper proposed a risk assessment method of ISAS considering human reliability. First, according to the operators work condition, estimate the human error probability based on analytic hierarchy process-smart substation automation system to correct the failure probability of physical devices. Then, adopt the function decomposition based method to assess the failure risk of functions. Finally, obtain the failure risk of ISAS by mixing the function risks to characterize the reliability of ISAS and offer guidance to dispatching department. The big impact of human reliability on the ISAS risk is demonstrated in case study, which means considering human reliability is more objective than the traditional method.

Key words: substation automation system, smart substation, human reliability
