在北美范围内，2012年保护系统误操作与自动输电中断严重程度的正相关性最大，且具有统计学意义。平均而言，有误操作的传输事件比没有误操作的传输事件更具影响力。总的来说，它们也是造成输电中断事件严重程度的最大因素。减少误操作将大大提高大电网的可靠性。此外，本文提出的概念框架和统计方法，确定可靠性的顶级风险。
On a North American-wide basis, protection system misoperations had the largest positive and statistically significant correlation with automatic transmission outage severity in 2012. On average, transmission events with misoperations were more impactful than transmission events without misoperations. They were also, in aggregate, the largest contributor to transmission outage event severity. A reduction of misoperations would lead to a great improvement in bulk power system reliability. Further, this paper presents the conceptual framework and statistical method that identify the top risks to reliability.
